What is NAOS? The Arizona Homeowner’s Guide to Natural Area Open Space

Natural Area Open Space (NAOS) is a protected part of a property in Arizona that is permanently designated to remain in its native desert state. While a homeowner owns the land, it is subject to an easement that restricts any building, landscaping, or clearing, making it a critical consideration for anyone buying, selling, or renovating a home in the region.

Understanding the Importance of NAOS

If you’re a homeowner or prospective buyer in Arizona, particularly in a city like Scottsdale, understanding NAOS (Natural Area Open Space) is essential. It’s a key component of the state’s efforts to preserve the Sonoran Desert. Simply put, NAOS is a deed-restricted area on a property that must be left in its natural condition, completely undisturbed by human activity.

The easement means that within the designated NAOS, you cannot:

• Build new structures like pools, sheds, or additions.
• Grade, fill, or excavate the land.
• Clear, prune, or rake existing native vegetation.

The purpose of NAOS is to protect native vegetation, wildlife habitats, and natural drainage patterns. This not only preserves the beauty of the desert but also helps with flood control and maintains the area’s unique ecosystem.

Know Where Natural Area Open Space is Located on Your Property

Before you plan any home improvement project, it’s crucial to know if and where a NAOS easement exists on your property. This information is typically recorded with the county and can be found on a title report or the subdivision plat. Knowing the exact location is the first step in avoiding costly violations.

We often encounter situations where homeowners are surprised by NAOS restrictions. For example, we worked with a client who wanted to add a beautiful new patio and retaining wall to their backyard. Upon reviewing their property documents, we discovered a significant portion of their yard was in Natural Area Open Space . By understanding the easement early on, we were able to redesign the project to fit within the buildable area of the property, avoiding potential fines and the expensive process of seeking a variance.

This is where expert structural guidance is invaluable. A NAOS violation can be a major hurdle, but with the right planning, it doesn’t have to stop your project. Schembri Engineers specializes in navigating these complexities. We work with homeowners and builders to ensure that structural designs are not only safe and robust but also fully compliant with local regulations, including NAOS easements.
