When you look at a new building, you see its beautiful facade, its functional layout, and its modern finishes. But beneath the surface lies its structural integrity. The stability and longevity of any building, from a custom home to a commercial complex, depend entirely on the principles of structural design and analysis.

At Schembri Engineers, we’ve been the trusted partner for countless builders and property owners across Arizona since 1985. We understand that our work is more than just drawing plans; it’s about creating a safe, durable, and reliable foundation for the future.

What is Structural Design?

Structural design is the art and science of shaping a building’s skeleton. It’s the process where engineers determine the most effective materials, sizes, and configurations for a structure’s components—like beams, columns, and foundations. The goal is to ensure the building can safely support all the loads it will face throughout its lifespan.

This includes:

• Static loads: The weight of the building itself and its contents.
• Dynamic loads: Forces from wind, seismic activity (earthquakes), and even heavy rainfall.
• Environmental factors: The specific challenges of Arizona’s climate, such as intense heat and shifting desert soils.

What is Structural Analysis?

If structural design is the plan, structural analysis is the critical quality check. This is the scientific, data-driven process of evaluating a proposed design. Using advanced mathematical models and software, our engineers simulate how a structure will perform under various conditions.

We analyze key factors to ensure the design is sound, including:

• Stress and Strain: Measuring how forces will affect the building’s materials.
• Load Distribution: Confirming that loads are correctly transferred through the structure to the ground.
• Deflection and Vibration: Ensuring the building won’t experience excessive movement that could compromise its integrity or comfort.

Through rigorous analysis, we can identify and correct potential weak points before construction even begins, saving time, money, and most importantly, ensuring safety.

The desert landscape of Arizona is beautiful, but it can also present unique challenges for residential properties. From shifting soils to the intense heat and monsoon moisture, your home’s structure is constantly under stress. Knowing the early warning signs of a potential problem can save you thousands of dollars and give you invaluable peace of mind.

At Schembri Engineers, we’ve been helping homeowners throughout Phoenix, Scottsdale, and the surrounding areas since 1985. Here are the top 10 signs that it may be time to call a professional structural engineer for an expert evaluation.

1. Cracks in Your Foundation, Walls, or Stucco

While hairline cracks can sometimes be cosmetic, larger or jagged cracks are a significant red flag. They can indicate soil settlement, foundation movement, or other serious structural issues that need a professional eye.

2. Doors or Windows that Stick or Won’t Close

If a door or window suddenly becomes difficult to open or close, it may be a sign of a misaligned frame caused by structural movement. Don’t just ignore it; this could be an early symptom of a shifting foundation.

3. Sagging Floors or Ceilings

A floor or ceiling that has a noticeable dip or “sag” often points to weakened or compromised support beams, joists, or trusses. This is a critical issue that requires an immediate inspection to prevent further damage.

4. Bowed or Leaning Walls

Exterior or interior walls that appear to be bowing inward or leaning outward are a clear indication of a structural problem. This can be caused by excessive pressure from the soil, a weakened foundation, or improper load-bearing support.

5. Water Intrusion or Persistent Moisture

While a plumber handles the pipes, a structural engineer can help if water is getting into your basement or crawl space. Persistent moisture can weaken a home’s foundation and lead to long-term structural damage.

6. Signs of Termite or Pest Damage

Termites and other pests can wreak havoc on wood framing, beams, and joists. After a pest control company has treated the problem, a structural engineer can assess the extent of the damage and design the necessary repairs.

7. Post-Fire or Natural Disaster Damage

If your home has experienced a fire, flood, or other disaster, a structural engineer is essential to evaluate the integrity of the remaining structure. Our forensic engineers can determine the safety of the building and design a plan for a safe rebuild.

8. Before a Major Renovation

Planning to remove a load-bearing wall, add a second story, or create an open-concept space? Before you start knocking down walls, you need a structural design from a professional to ensure your home remains safe and sound.

9. As Part of a Pre-Purchase Inspection

Before you buy a new home, a specialized structural inspection can give you complete peace of mind. Our team, which includes a Board Certified Building Inspection Engineer, can identify hidden problems that a standard home inspection might miss.

10. You’re Building a New Custom Home

A structural engineer is a crucial partner in the design phase of a new build. At Schembri Engineers, our design and engineering services ensure your custom home is built to the highest standards of safety and durability from the very beginning.

ASTM E2018 – 08 Standard Guide for Property Condition Assessments: Baseline Property Condition Assessment Process
Significance and Use

Use—This guide is intended for use on a voluntary basis by parties who desire to obtain a baseline PCA of commercial real estate. This guide also recognizes that there are varying levels of property condition assessment and due diligence that can be exercised that are both more and less comprehensive than this guide, and that may be appropriate to meet the objectives of the user. Users should consider their requirements, the purpose that the PCA is to serve, and their risk tolerance level before selecting the consultant and the level of due diligence to be exercised by the consultant. The user should also review or establish the qualifications, or both, of the proposed field observer and PCR reviewer prior to engagement. A PCR should identify any deviations or exceptions to this guide. Furthermore, no implication is intended that use of this guide be required in order to have conducted a property condition assessment in a commercially prudent and reasonable manner. Nevertheless, this guide is intended to reflect a reasonable approach for the preparation of a baseline PCA.

Clarification of Use:

Specific Point in Time—A user should only rely on the PCR for the point in time at which the consultant’s observations and research were conducted.

Site-Specific—The PCA performed in accordance with this guide is site-specific in that it relates to the physical condition of real property improvements on a specific parcel of commercial real estate. Consequently, this guide does not address many additional issues in real estate transactions such as economic obsolescence, the purchase of business entities, or physical deficiencies relating to off-site conditions.

Who May Conduct—The walk-through survey portion of a PCA should be conducted by a field observer, and the PCR should be reviewed by a PCR reviewer; both qualified as suggested in X1.1.1.1 and X1.1.1.2, respectively.

Principles—The following principles are an integral part of this guide. They are intended to be referred to in resolving ambiguity, or in exercising discretion accorded the user or consultant in conducting a PCA, or in judging whether a user or consultant has conducted appropriate inquiry or has otherwise conducted an adequate PCA.

Uncertainty Not Eliminated—No PCA can wholly eliminate the uncertainty regarding the presence of physical deficiencies and the performance of a subject property’s building systems. Preparation of a PCR in accordance with this guide is intended to reduce, but not eliminate, the uncertainty regarding the potential for component or system failure and to reduce the potential that such component or system may not be initially observed. This guide also recognizes the inherent subjective nature of a consultant’s opinions as to such issues as workmanship, quality of original installation, and estimating the RUL of any given component or system. The guide recognizes a consultant’s suggested remedy may be determined under time constraints, formed without the aid of engineering calculations, testing, exploratory probing, the removal or relocation of materials, design, or other technically exhaustive means. Furthermore, there may be other alternative or more appropriate schemes or methods to remedy a physical deficiency. The consultant’s opinions generally are formed without detailed knowledge from those familiar with the component’s or system’s performance.

Not Technically Exhaustive—Appropriate due diligence according to this guide is not to be construed as technically exhaustive. There is a point at which the cost of information obtained or the time required to conduct the PCA and prepare the PCR may outweigh the usefulness of the information and, in fact, may be a material detriment to the orderly and timely completion of a commercial real estate transaction. It is the intent of this guide to attempt to identify a balance between limiting the costs and time demands inherent in performing a PCA and reducing the uncertainty about unknown physical deficiencies resulting from completing additional inquiry.

Representative Observations—The purpose of conducting representative observations is to convey to the user the expected magnitude of commonly encountered or anticipated conditions. Recommended representative observation quantities for various asset types are provided in Annex A1; however, if in the field observer’s opinion such representative observations as presented in Annex A1 are unwarranted as a result of homogeneity of the asset or other reasons deemed appropriate by the field observer, the field observer may survey sufficient units, areas, systems, buildings, etc. so as to comment with reasonable confidence as to the representative present condition of such repetitive or similar areas, systems, buildings, etc. To the extent there is more than one building on the subject property, and they are homogeneous with respect to approximate age, use, basic design, materials, and systems, it is not a requirement of this guide for the field observer to conduct a walk-through survey of each individual building’s systems to describe or comment on their condition within the PCR. The descriptions and observations provided in the PCR are to be construed as representative of all similar improvements.

User-Mandated Representative Observations—A user may mandate the representative observations required for a given property or a particular building system. Such representative observations may be more or less than this guide’s recommended representative observations as provided in Annex A1.

Extrapolation of Findings—Consultant may reasonably extrapolate representative observations and findings to all typical areas or systems of the subject property for the purposes of describing such conditions within the PCR and preparing the opinions of probable costs for suggested remedy of material physical deficiencies.

Level of Due Diligence is Variable—Not every property will warrant the same level of property condition assessment. Consistent with good commercial and customary practice, the appropriate level of property condition assessment generally is guided by the purpose the PCA is to serve; type of property; age of the improvements; expertise and risk tolerance level of the user; and time available for preparing the PCR and reviewing the opinions to be contained in the PCR.

Prior PCR Usage—This guide recognizes that PCRs performed in accordance with this guide may include information that subsequent users and consultants may want to use to avoid duplication and to reduce cost. therefore, this guide includes procedures to assist users and consultants in determining the appropriateness of using such information. In addition to the specific procedures contained elsewhere in this guide, the following should be considered:

Use of Prior PCR Information—Information contained in prior property condition reports may be used by the consultant if, in the consultant’s opinion, it is relevant; however, users and consultants are cautioned that information from prior property condition reports should only be used if such information was generated or obtained through procedures or methods that met or exceeded those contained in this guide. Such information should serve only as an aid to a consultant in fulfilling the requirements of this guide and to assist the field observer in the walk-through survey, research, and the field observer’s understanding of the subject property. Furthermore, the PCR should identify the previously prepared property condition report if information from the prior report was used by the consultant in preparing the PCR.

Comparison with a Previously Prepared PCR—It should not be concluded or assumed that a previous PCR was deficient because the previous PCA did not discover a certain or particular physical deficiency, or because opinions of probable costs in the previous PCR are different. A PCR contains a representative indication of the property condition at the time of the walk-through survey and is dependent on the information available to the consultant at that time. Therefore, a PCR should be evaluated on the reasonableness of judgments made at the time and under the circumstances in which they are made. Experience of the field observer, the requirements of the previous PCR’s client or the purpose of the previous PCR, time available to the consultant to complete the PCR, hindsight, new or additional information, enhanced visibility as a result of improved weather or site conditions, equipment visibility as a result of improved weather or site conditions, equipment not in a shutdown mode, and other factors influence the PCA and the opinions contained in the PCR.

Conducting Current Walk-Through Surveys—Except as provided in 3.5.1, prior property condition reports should not be used without verification. At a minimum, for a PCR to be consistent with this guide, a new walk-through survey, interviews, and solicitation and review of building and fire department records for recorded material violations should be performed.

Actual Knowledge Exception—If the user or consultant conducting a PCA has actual knowledge that the information from a prior property condition report is not accurate, or if it is obvious to the field observer that the information is not accurate, such information from a prior property condition report should not be used.

Contractual Issues—This guide recognizes that contractual and legal obligations may exist between prior and subsequent users of property condition reports, or between clients and consultants who prepared prior property condition reports, or both. Consideration of such contractual obligations is beyond the scope of this guide. Furthermore, a subsequent user of a prior PCR should be apprised that it may have been prepared for purposes other than the current desired purpose of the PCR and should determine the contractual purpose and scope of the prior PCR.

Rules of Engagement—The contractual and legal obligations between a consultant and a user (and other parties, if any) are outside the scope of this guide. No specific legal relationship between the consultant and the user was considered during the preparation of this guide.

1. Scope

1.1 Purpose—The purpose of this guide is to define good commercial and customary practice in the United States of America for conducting a baseline property condition assessment (PCA) of the improvements located on a parcel of commercial real estate by performing a walk-through survey and conducting research as outlined within this guide.

1.1.1 Physical Deficiencies—In defining good commercial and customary practice for conducting a baseline PCA, the goal is to identify and communicate physical deficiencies to a user. The term physical deficiencies means the presence of conspicuous defects or material deferred maintenance of a subject property’s material systems, components, or equipment as observed during the field observer’s walk-through survey. This definition specifically excludes deficiencies that may be remedied with routine maintenance, miscellaneous minor repairs, normal operating maintenance, etc., and excludes de minimis conditions that generally do not present material physical deficiencies of the subject property.

1.1.2 Walk-Through Survey—This guide outlines procedures for conducting a walk-through survey to identify the subject property’s physical deficiencies, and recommends various systems, components, and equipment that should be observed by the field observer and reported in the property condition report (PCR).

1.1.3 Document Reviews and Interviews—The scope of this guide includes document reviews, research, and interviews to augment the walk-through survey so as to assist the consultant’s understanding of the subject property and identification of physical deficiencies.

1.1.4 Property Condition Report—The work product resulting from completing a PCA in accordance with this guide is a Property Condition Report (PCR). The PCR incorporates the information obtained during the Walk-Through Survey, the Document Review and Interviews sections of this guide, and includes Opinions of Probable Costs for suggested remedies of the physical deficiencies identified.

1.2 Objectives—Objectives in the development of this guide are to: (1) define good commercial and customary practice for the PCA of primary commercial real estate improvements; (2) facilitate consistent and pertinent content in PCRs; (3) develop pragmatic and reasonable recommendations and expectations for site observations, document reviews and research associated with conducting PCAs and preparing PCRs; (4) establish reasonable expectations for PCRs; (5) assist in developing an industry baseline standard of care for appropriate observations and research; and (6) recommend protocols for consultants for communicating observations, opinions, and recommendations in a manner meaningful to the user.

1.3 Considerations Beyond Scope—The use of this guide is strictly limited to the scope set forth in this section. Section 11 and Appendix X1 of this guide identify, for informational purposes, certain physical conditions that may exist on the subject property, and certain activities or procedures (not an all inclusive list) that are beyond the scope of this guide but may warrant consideration by parties to a commercial real estate transaction to enhance the PCA.

1.4 Organization of This Guide—This guide consists of several sections, an Annex and two (2) Appendixes. Section 1 is the Scope. Section 2 on Terminology contains definitions of terms both unique to this guide and not unique to this guide, and acronyms. Section 3 sets out the Significance and Use of this guide, and Section 4 describes the User’s Responsibilities. Sections 5 through 10 provide guidelines for the main body of the PCR, including the scope of the Walk-Through Survey, preparation of the Opinions of Probable Costs to Remedy Physical Deficiencies, and preparation of the PCR. Section 11 provides additional information regarding out of scope considerations (see 1.3). Annex A1 provides requirements relating to specific asset types, and where applicable, such requirements are to be considered as if integral to this guide. Appendix X1 provides the user with additional PCA scope considerations, whereby a user may increase this guide’s scope of due diligence to be exercised by the consultant beyond this guide’s baseline level. Appendix X2 outlines the ADA Accessibility Survey.

1.5 Multiple Buildings—Should the subject property consist of multiple buildings, it is the intent of this guide that only a single PCR be produced by the consultant to report on all of the primary commercial real estate improvements.

1.6 Safety Concerns—This guide does not purport to address all of the safety concerns, if any, associated with the walk-through survey. It is the responsibility of the consultant using this guide to establish appropriate safety and health practices when conducting a PCA.

That’s a question that we never want to ask and a GFCI can help protect our kids.

What is a GFCI? 

A GFCI, or Ground Fault Circuit Interrupter, is an automatic device that offers personal protection against electrical shock. They are installed in areas where known electrical shock hazards exist… outdoor outlets and fixtures, swimming pools, saunas and hot tubs, outlets in kitchens, basements, bathrooms, and garages.  Wherever there is the potential for contact between a person and an electrical appliance in or near moisture, water, or water piping, a GFCI should be protecting the circuit… and you!

How Does a GFCI Work?

Inside of a GFCI is a sensor that detects changes in current to the appliance by comparing the current flowing to the appliance and the current flowing from the appliance.  A drop off in the current equivalent to about 5 milli-amperes turns off all power by tripping a relay within the GFCI within a few hundredths of a second. You might hardly even feel the shock, it happens so quickly!

However, there is still a danger since 5 mille-amperes can cause a “jerk reflex” or spasm in the muscles.  This is not too bad if you are standing on the ground but potentially dangerous if you are on a ladder or roof!

GFCI’s can be reset to restore power to the affected circuit.  If the problem still exists, though, the GFCI will not reset.

Types of GFCIs.

The three basic types used in homes are the GFCI outlet, the GFCI circuit breaker and the portable GFCI. All perform the same function each has different applications and limitations.

The GFCI outlet (shown above) is intended as a replacement for a standard electrical outlet. It protects any appliance plugged into it, and can also be wired to protect other outlets that are connected to it.

IMPORTANT:  A GFCI outlet is not difficult to install, but the instructions for installation and testing must be followed precisely to insure the GFCI works properly!!

The GFCI circuit breaker controls an entire circuit, and is installed as a replacement for a circuit breaker on your home’s main circuit board. Some homes are wired so that all bathrooms or all outdoor fixtures are on the same circuit. Rather than install multiple GFCI outlets, one GFCI circuit breaker can protect the entire circuit.

If you decide that the GFCI circuit breaker is your best option, you must purchase one that is a match for your main electrical panel. If you have an older panel that utilizes fuses, you cannot use a GFCI circuit breaker and must use GFCI outlets instead.

Resetting a GFCI circuit breaker is a little different than resetting an outlet-type GFCI.  There is no “reset” switch.  Instead, the GFCI breaker is reset by first switching the breaker to the full “off” position, then to the full “on” position to restore power.

There is also a portable GFCI that is often used by contractors as shown below:
They can work as well as the ones installed in your house. In fact, some appliances such as hair dryers are now coming from the factory with GFCIs built into the power cords.  Portable GFCI’s are frequently used by contractors on worksites.

Portable GFCIs do not need a ground to function, since they are designed the same as stationary ones. So if the GFCI is operating properly, it will protect you even in ungrounded situations.  However, if the tool or appliance you are using has a grounded three prong plug, you should never defeat it with an adapter unless you ground the adapter.  The GFCI will offer no protection from the type of shock that can result from improper grounding of the tool!!

Always perform a safety test on your portable GFCI each time before using it. Push the TEST button, which should kill power to the outlets.  Then, press the reset button to restore power to the GFCI outlets.

IMPORTANT NOTE: Do not use portable GFCIs in place of permanent ones in your home! They are intended to be used in situations where you must bring power from an unprotected outlet into a hazardous situation. For example, if you ran an extension cord from a living room outlet (probably unprotected) to the front yard to cut lumber on the lawn!

Testing a GFCI

All GFCIs, whether local or central, have two testing-related buttons on them.  One button is appropriately labeled TEST, and one is labeled RESET.  Turn on an appliance or light fixture connected to the GFCI.  Press the TEST button, and the appliance should immediately turn off.  If it does not, either the GFCI is miswired, there is a problem with other wiring in the same circuit, or the GFCI has malfunctioned and should be replaced.  Pressing the RESET button will restore power to the appliance or circuit.

Conversely, if you have a GFCI that has tripped and will not reset, you may have a wiring short in the circuit, a defective appliance on the circuit, or the GFCI itself has become defective.

The easiest way to troubleshoot a GFCI is to obtain a GFCI tester, available at most hardware stores. It plugs into the GFCI outlet, and will supply you with a “snapshot” of your connections, indicating wiring problems and/or the condition of the GFCI. Another way to troubleshoot is to simply purchase a new GFCI and install it.

The GFCI in my kitchen seems to trip more often. Do GFCIs wear out?

Yes, they sure do! Over time, a GFCI will become more sensitive to minor variations in current that are caused by certain types of appliances. Hair dryers and space heaters are notorious for stressing and tripping GFCIs.  Replacing the GFCI will help solve this problem, though it may recur eventually as the new GFCI ages.

Does a GFCI need to be grounded to work properly? I would like to install a GFCI in my bathroom but the outlet is the old, 2-pronged type.

According to the NEC, it is allowable to install GFCI’s in ungrounded situations. This makes sense, since the GFCI is not dependent of the ground to function. Remember, it does not measure shorts to the ground, it measures the current difference between the hot and neutral wires. A sudden difference, indicating that there is another path for the electricity to flow through… you, for example, causes the GFCI to open the circuit and save you from permanently curly hair.

Of course, most safety-conscious electricians prefer not to install a grounded-type “three prong” outlet in an ungrounded situation.  Think about it… once the outlet is installed, there is no way for anyone to know if the outlet is really grounded or not without testing it.  Thus, there is a hidden shock hazard should an appliance or tool that needs grounding… has three-prong plug…  is plugged into this outlet.

However, the NEC allows GFCI’s to be installed in ungrounded situations PROVIDED THAT the outlet is labeled “ungrounded”.  Though not “officially” approved in the NEC, the grounding hole in the GFCI can be permanently defeated by using an epoxy or other adhesive to seal the hole.

Though a GFCI will activate if a grounded appliance develops an electrical short circuit to ground… such as when YOU touch a metal saw and become the path to ground… you will experience a momentary electrical shock.  This could be a minor tingle or could be more catastrophic, especially if you are on a ladder or roof.  This excerpt is from an OSHA (Occupational Safety and Health Administration) article on wiring in nursing homes and the dangers to employees working with ungrounded outlets…

“The ground-fault circuit interrupter, on the other hand, is a fast-acting device which senses small current leakage to ground and, in a fraction of a second, shuts off the electricity and interrupts its faulty flow to ground. The rapid response of the GFCI is fast enough to prevent electrocution and this protection is independent of the condition of the grounding conductor.

A GFCI can prevent an electrocution; however, it cannot by itself prevent an initial electric shock to an employee before it interrupts the circuit. This initial shock could lead to injuries of an indirect or secondary nature in which involuntary muscular reaction could cause bruises, bone fractures, and even death resulting from collisions or falls. Therefore, GFCIs are in addition to, and not in lieu of, equipment grounding conductor requirements.”

Here’s a link to the complete article:  http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=FEDERAL_REGISTER&p_id=13346 )

Are there any situations in which a GFCI will not provide the shock protection for which it as designed?

GFCI’s are not effective in certain circumstances.  As mentioned earlier, they work by measuring the difference between the electrical current going INTO an appliance and the current going OUT of the appliance.  This assumes that the person being shocked is grounded.   If you were ungrounded and touched the hot and neutral wires at the same time, there would be no drop in current detected, so the GFCI would not activate.  Then, you would be at the mercy of the fuses or circuit breakers, which may or may not stop the current before it’s too late!

A second situation where a GFCI will not protect you is when a second, unprotected circuit is involved in an accident.  This can happen when a wire is accidentally drilled into or a metal screw penetrates a wire hidden in the wall.  Unless this second circuit is also protected, you are at full risk of electrocution, even if the tool itself is on a protected circuit!

Arc Faults

Problems in home wiring, like arcing and sparking, are associated with more than 40,000 home fires each year. These fires claim over 350 lives and injure 1,400 victims annually.

A new electrical safety device for homes, called an arc fault circuit interrupter or AFCI, is expected to provide enhanced protection from fires resulting from these unsafe home wiring conditions.

Typical household fuses and circuit breakers do not respond to early arcing and sparking conditions in home wiring. By the time a fuse or circuit breaker opens a circuit to defuse these conditions, a fire may already have begun.

Several years ago, a CPSC study identified arc fault detection as a promising new technology. Since then, CPSC electrical engineers have tested the new AFCIs on the market and found these products to be effective.

Requiring AFCIs

AFCIs are already recognized for their effectiveness in preventing fires. The most recent edition of the National Electrical Code, the widely-adopted model code for electrical wiring, will require AFCIs for bedroom circuits in new residential construction, effective January 2002.

Future editions of the code, which is updated every three years, could expand coverage.

AFCIs vs. GFCIs

AFCIs should not be confused with ground fault circuit interrupters or GFCIs. The popular GFCI devices are designed to provide protection from the serious consequences of electric shock.

While both AFCIs and GFCIs are important safety devices, they have different functions. AFCIs are intended to address fire hazards; GFCIs address shock hazards. Combination devices that include both AFCI and GFCI protection in one unit will become available soon.

AFCIs can be installed in any 15 or 20-ampere branch circuit in homes today and are currently available as circuit breakers with built-in AFCI features. In the near future, other types of devices with AFCI protection will be available.

Should You Install AFCIs?

You may want to consider adding AFCI protection for both new and existing homes. Older homes with ordinary circuit breakers especially may benefit from the added protection against the arcing faults that can occur in aging wiring systems.

For more information about AFCIs, contact an electrical supply store, an electrician, or the manufacturer of the circuit breakers already installed in your home. Sometimes these components can be replaced with AFCIs in the existing electrical panel box.

Be sure to have a qualified electrician install AFCIs; do not attempt this work yourself. The installation involves working within electrical panel boxes that are usually electrically live, even with the main circuit breakers turned off.

If you have any doubts about the need to replace your poly pipes, take a look at the pictures of a home that suffered from a single leak. These homeowners were away on vacation when a leak developed in the upstairs bathroom. More than 27,000 gallons of water ran through their home.
When they returned, there was four feet of water in the basement and $138,000 worth of damage to their furniture, carpets, wallpaper, wallboard, ceilings and priceless family heirlooms.

“Cascading water ruptured the ceiling in several places on the main level and poured down onto [Milton and Rhonda Schultz’s] kitchen cabinets, newly decorated walls and oak floor. From there, it spilled into the living room and family room, destroying carpeting in its wake, and sloshed downstairs to the basement.” —-Kenneth Lelen, Washington Post, May 16, 1998

A form of real estate ownership of a multifamily residential dwelling. Each occupant has 100% ownership of his own apartment and partial ownership of common elements such as hallways, elevators, plumbing, etc.  Also see cooperative.
This article refers to a form of housing. For information on the international law describing a territory in which two sovereign powers have equal rights, please see condominium (international law).

A condominium, or condo for short, is a form of housing tenure.  It is the legal term used in the United States and in most provinces of Canada for a type of joint ownership of real property in which portions of the property are commonly owned and other portions are individually owned.  In Australia and the Canadian province of British Columbia, the legal term for this is strata title.  In Quebec, it is known as syndicates of co-ownership. In England and Wales the equivalent is common hold, but this form of ownership was only introduced in 2004 and so far is hardly used. Colloquially, the term “condo” is often used to refer to the apartment unit itself in place of the term “apartment”. This clearly signifies ownership of the property.

Discussion

Often, a condominium consists of units in a multi-unit dwelling (i.e., an apartment or a development) where each unit is individually owned and the common areas such as hallways and recreational facilities are jointly owned (usually as “tenants in common”) by all the unit owners in the building. It is possible, however, for condominiums to consist of single family dwellings: so-called “detached condominiums” where homeowners do not maintain the exteriors of the dwellings, yards, etc. or “site condominiums” where the owner has more control and possible ownership (as in a “whole lot” or “lot line” condominium) over the exterior appearance. These structures are preferred by some planned neighborhoods and gated communities.

A homeowners association, consisting of all the members, manages the common areas usually through a board of directors elected by the members. The same concept exists under different names depending on the jurisdiction, such as “unit title”, “sectional title”, “common hold,” “strata council,” or “tenant-owner’s association”, “body corporate”, “Owners Corporation”, “condominium corporation” or “condominium association.” Another variation of this concept is the “time share” although not all time shares are condominiums, and not all time shares involve actual ownership of (i.e., deeded title to) real property. Condominiums may be found in both civil law and common law legal systems as it is purely a creation of statute.

The rules for condominium government or management are established in a document commonly called a declaration of condominium. The owners and occupiers of condominiums are subject to rules in the declaration of condominium or created by the condominium association, such as paying required monthly fees for maintaining the property’s common areas. Condominiums are commonly owned in fee simple title, but can be owned in ways other real estate can be owned, such as title held in trust. In some jurisdictions, such as Ontario, Canada, there are also “leasehold condominiums” where the development is built on leased land.

In general, condominium unit owners can typically rent their condominiums to other people to occupy as tenants, similar to renting out other real estate, although such leasing rights may be subject to conditions or restrictions set out in the condominium declaration or otherwise as permitted by law applicable in the jurisdiction.

Non-residential condominiums

Condominium ownership is also used, albeit less frequently, for non-residential land uses like offices, hotel rooms, retail shops, and group housing facilities like retirement homes or dormitories. The legal structure is the same, and many of the benefits are similar; for instance, a nonprofit corporation may face a lower tax liability in an office condominium than in an office rented from a taxable, for-profit company. However, the frequent turnover of commercial land uses in particular can make the inflexibility of condominium arrangements problematic.

An alternative form of ownership, popular in the United States but found also in other common law jurisdictions, is the “cooperative” corporation, also known as “company share” or “co-op”, in which the building has an associated legal company and ownership of shares gives the right to a lease for residence of a unit. Another form is leasehold or ground rent in which a single landlord retains ownership of the land on which the building is constructed in which the lease renews in perpetuity or over a very long term such as in a civil law emphyteutic lease. Another form of civil law joint property ownership is undivided co-ownership where the owners own a percentage of the entire property but have exclusive possession of a specific part of the property and joint possession of other parts of the property; distinguished from joint tenancy with right of survivorship or a tenancy in common of common law.

The first condominium law passed in the United States was passed by the Commonwealth of Puerto Rico in 1958. Common law tradition holds that real property ownership must involve land, whereas the French civil law tradition recognized condominium ownership as early as the 1804 Napoleonic Code; thus, it is notable that condominiums evolved in the United States via a Caribbean government with a hybrid common-civil legal system. In 1960, the first condominium in the Continental United States was built in Salt Lake City, Utah. Initially designed as a housing cooperative (Co-op), the Utah Condominium Act of 1960 made it possible for “Graystone Manor” (2730 S 1200 East) to be built as a condominium. The legal counsel for the project, Keith B. Romney is also credited with authoring the Utah Condominium act of 1960. Romney also played an advisory role in the creation of condominium legislation with every other legislature in the U.S. Business Week hailed Romney as the “Father of Condominiums”. He soon after formed a partnership with Don W. Phil called “Keith Romney Associates”, which was widely recognized throughout the 1970’s as America’s preeminent condominium consulting firm. ^[1] Although often mistakenly credited with coining the term “Condominium“, Romney has always been quick to point out that the term hails back to Roman times, and that he merely borrowed it.

Section 234 of the 1961 National Housing Act allowed the Federal Housing Administration to insure mortgages on condominiums, which led to a vast increase in the capital available for condominiums and to condominium laws in every state by 1969. Americans’ first taste of condominium life came not from its largest cities but from south Florida, where developers had first imported the condominium concept from Puerto Rico and used it to sell thousands of inexpensive apartments to retirees arriving with equity earned from the urban North.

Canada – Ontario

In Ontario, condominiums are governed by the Condominium Act, 1998 with each development establishing a corporation to deal with day-to-day functions (maintenance, repairs, etc…). A board of directors is elected by the owners of units (or, in the case of a common elements condominium corporation, the owners of the common interest in the common elements) in the development on at least a yearly basis. A general meeting is held annually to deal with board elections and the appointment of an auditor (or waiving of audit). Other matters can also be dealt with at the Annual General Meeting, but special meetings of the owners can be called by the board and, in some cases, by the owners themselves, at any time.

In recent years the condo industry has been booming in Canada, with dozens of new condo towers being erected each year. Toronto is the epicenter of this boom, with 17,000 new units being sold in 2005, more than double second place Miami’s 7,500 units [1]. For several years now that city’s sky line has had a forest of cranes erecting new towers. Outside of Toronto, the most common forms of condominium have been townhomes rather than high-rises, although that trend may be altered as limitations are placed on “Greenfields” (see Greenfield land) developments in those areas (in turn, forcing developers to expand upward rather than outward and to consider more condominium conversions instead of new housing). Particular growth areas are in Kitchener Waterloo and London. In fact, after Toronto, the Institute is one of that organization’s most thriving chapters.

The Ontario Condominium Act, 1998 provides an effectively wide range of development options, including Standard, Phased, Vacant Land, Common Element and Leasehold condominiums. Certain existing condominiums can amalgamate, and existing properties can be converted to condominium (provided municipal requirements for the same are met). Accordingly, the expanded and expanding use of the condominium concept is permitting developers and municipalities to consider newer and more interesting forms of development to meet social needs.

On this issue, Ontario condominium lawyer Michael Clifton writes, “Condominium development has steadily increased in Ontario for several years. While condominiums typically represent attractive lifestyle and home-ownership alternatives for buyers, they also, importantly, introduce a new approach to community planning for home builders and municipal approval authorities in Ontario. …[There are] opportunities for developers to be both creative and profitable in building, and municipalities more flexible and imaginative in planning and approving, developments that will become sustainable communities.” (In, A Comment about Condominiums, Community Planning and Sustainability, Forum Magazine, Dec 06/Jan 07, p. 28.)

In architecture, a deck is a flat surface capable of supporting weight, similar to a floor, but typically constructed outdoors, often elevated from the ground, and usually connected to a building. The term is a generalization of decks as found on ships.

Wood or timber “decking” can be used in a number of ways – as part of garden landscaping, to extend living areas of houses, and as an alternative to stone based features such as patios. Decks are made from treated lumber, composite material, Aluminum, Western red cedar, teak, mahogany, ipê and other hardwoods and recycled planks made from high-density polyethylene (HDPE), polystyrene (PS) and PET plastic as well as mixed plastics and wood fiber (often called “composite” lumber).

Historically, the softwoods used for decking were logged from old growth forests. These include Atlantic white cedar, redwood and Western red cedar (red cedar). Atlantic City built the first coastal boardwalk in the United States, originally constructed of Atlantic white cedar. However, it was not long before the commercial logging of this tree and clearing of cedar swamps in New Jersey caused a decline in the availability of decking. Atlantic City and New York City both switched to Western red cedar. By the 1960s, Western red cedar from the US was declining due to over-logging. More expensive Western red cedar was available from western Canada (British Columbia) but by then, pressure treated pine had become available.

But even with chemical treatments (such as chromated copper arsenate or CCA), pine decking is not as durable as cedars in an outdoor environment. Thus, many municipalities and homeowners are turning to hardwoods.

Generally, hardwoods used for decking come from tropical forests. Much of the logging taking place to produce these woods, especially teak, mahogany and ipê, is occurring illegally, as outlined in numerous reports by environmental organizations such as Greenpeace, Friends of the Earth and Rainforest Relief. US tropical wood imports are rising, partly due to the demand for decking.

The deck of a house is generally a wooden platform built above the ground and connected to the main building. It is generally enclosed by a railing for safety. Access may be from the house through doors and from the ground via a stairway. Residential decks can be constructed over steep areas or rough ground that is otherwise unusable. Decks can also be covered by a canopy or pergola to control sunlight.

Larger buildings may also have decks on the upper floors of the building which may be open to the public as observation decks.

A deck is also the surface used to construct a boardwalk over sand on barrier islands.

Deck Yearly Checklist:

• Inspect the joint between the house and the deck.
• From underneath the deck, observe the condition of the top of the deck joists.
• The guardrail should be checked for secure attachment to the deck surface.
• Check the decks foundations/support points.
• Determine if paint, stain or preservative needs to be applied to all exposed surfaces. The hot Arizona sun is brutal on these surfaces. Remove all splinters from the deck surface.
• Check with your local building code enforcement official to determine if the guardrails and railings are constructed per local code requirements.

Patios

A patio (from the Spanish: patio meaning ‘back garden’ or ‘backyard) is an outdoor space generally used for dining or recreation that often adjoins a residence and is typically paved. It may refer to a roofless inner courtyard of the sort found in Spanish-style dwellings or a paved area between a residence and the garden.

Patios are typically made of concrete or stone slabs laid over a firm base. This base is often formed of a layer of compacted hardcore (stone chips), a layer of sharp sand, and a layer of cement mortar. The firmness and stability of the base is essential to the robustness of the top layer of slabs – an infirm base will typically result in cracked slabs. Patios that hold a lot of weight, such as driveways, require stronger foundations than those that are designed for light use. Patios are more common in Arizona than decks. Most homes in Arizona have concrete slab-on-grade patios installed at the rear of the home and covered. Very often the rear patio will adjoin the pool patio area.

Deck Yearly Checklist:

• It is important that the concrete patios be sloped at a 5% grade away from the house. This will keep water from draining towards the foundation which can lead to slab movement and foundation problems.
• Clean the deck with a commercially available concrete cleaner. Dirty patios can become slippery when wet.
• Check for cracks and seal with a high quality epoxy based crack filler material. Any cracks that have vertically displaced more than ¼ inch need to be ground down to eliminate any tripping hazard.

What is Polybutlylene?

Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995. Due to the low cost of the material and ease of installation, polybutylene piping systems were viewed as “the pipe of the future” and were used as a substitute for traditional copper piping. It is most commonly found in the “Sun Belt” where residential construction was heavy through the 1980’s and early-to-mid 90’s, but it is also very common in the Mid Atlantic and Northwest Pacific states.

These are typically gray or white in color with a dull finish. Most are shown with pipe attached. Figure (4) is a new fitting.

The piping systems were used for underground water mains and as interior water distribution piping. Industry experts believe it was installed in at least 6 million homes, and some experts indicate it may have been used in as many as 10 million homes. Most probably, the piping was installed in about one in every four or five homes built during the years in which the pipe was manufactured.

How to Tell If You Have Poly Exterior – Polybutylene underground water mains are usually blue, but may be gray or black (do not confuse black poly with polyethelene pipe). It is usually 1/2″ or 1″ in diameter, and it may be found entering your home through the basement wall or floor, concrete slab or coming up through your crawlspace; frequently it enters the home near the water heater. Your main shutoff valve is attached to the end of the water main. Also, you should check at the water meter that is located at the street, near the city water main. It is wise to check at both ends of the pipe because we have found cases where copper pipe enters the home, and poly pipe is at the water meter. Obviously, both pipes were used and connected somewhere underground.

Interior – Polybutylene used inside your home can be found near the water heater, running across the ceiling in unfinished basements, and coming out of the walls to feed sinks and toilets. Warning: In some regions of the country plumbers used copper “stub outs” where the pipe exits a wall to feed a fixture, so seeing copper here does not mean that you do not have poly.

Will the Pipes Fail? While scientific evidence is scarce, it is believed that oxidants in the public water supplies, such as chlorine, react with the polybutylene piping and acetal fittings causing them to scale and flake and become brittle. Micro-fractures result, and the basic structural integrity of the system is reduced. Thus, the system becomes weak and may fail without warning causing damage to the building structure and personal property. It is believed that other factors may also contribute to the failure of polybutylene systems, such as improper installation, but it is virtually impossible to detect installation problems throughout an entire system.

Throughout the 1980’s lawsuits were filed complaining of allegedly defective manufacturing and defective installation causing hundreds of millions of dollars in damages. Although the manufacturers have never admitted that poly is defective, they have agreed to fund the Class Action settlement with an initial and minimum amount of $950 million. You’ll have to contact the appropriate settlement claim company to find out if you qualify under this settlement.

“A series of reports have suggested that increased use of chloramines accelerates corrosion and degradation of some metals and elastomers common to distribution plumbing and appurtenances. With regard to elastomers, the study showed that with few exceptions, solutions of chloramines (either monochloramine or dichloramine) produced greater material swelling, deeper and more dense surface cracking, a more rapid loss of elasticity, and greater loss of tensile strength than equivalent concentrations of free chlorine.” —-Steven Reiber, HDR Engineering, American Water Works Association Research Foundation

 How Do I Get Rid of Polybutylene? There are two types of poly replacement, Interior and Exterior. Exterior poly runs from the main street lines serviced by the city to your house. You are responsible for the portion from your home to the city hook up. And many of these underground lines were installed using poly. Interior poly lines run inside your home, behind your walls and under your floors. Following is information pertaining to how to replace both, Interior and Exterior poly. 

EXTERIOR: There are several factors that determine the process of replacing your underground water main. First, you must consider the depth underground. In the “Sun Belt” where the frost line is shallow, a trencher is used for excavation because it is economical for clients, and it causes very little damage to the landscaping. When a trencher is used, the entire job takes about six hours, and your yard will show very few signs of all the work that went into installing the water main. “Last Sunday my exterior polybutylene pipe broke. It caused a huge sink hole in the front yard and flooded my basement with about five inches of water.” —-Sabrina Greer, Germantown, Maryland In parts of the country where the frost line is deep, a device is pulled through the old line that splits it while simultaneously pulling new copper piping through the old, expanded line. For deep installations, this process is very economical and requires very little disturbance to your yard or interior. In a few instances, however, pulling the pipe is not feasible, a trench must be excavated. When this process is used, the excavated dirt is piled onto plastic sheeting to protect the landscaping, and demolition of interior concrete is usually limited to a small area which is draped-off with plastic to control dust. With either process, the yard and interior concrete is restored as necessary, and the work is completed in about six to twelve hours.

INTERIOR: The process begins by mapping out the existing plumbing system and then selectively cutting a limited number of holes in the walls.  Technicians strategically decide on where to make the least number of cuts to do the job right. If someone tells you they need to start ripping apart entire walls, escort them out of your home. And if someone tells you they can’t do the drywall themselves, you know you’re in trouble. Our experts provide you with a turnkey operation from plumbing to drywall to final restoration and computerized matching of your paint. In an average-sized home, 20-30 discreetly placed cuts are made. From these entry points brand-new copper plumbing is installed.
