Building ADUs for Phoenix Homes

Here at Phoenix ADU Solutions, Inc., we build Accessory Dwelling Units for homeowners across the Valley. Our process starts with a full site analysis. We look closely at Phoenix's soil conditions, especially the expansive clays. This often means we plan for deeper footings or engineered slabs to stop settlement problems later on.

We also plan for the strong Arizona sun. We put in passive cooling strategies and choose good quality, Low-Emissivity (Low-E) windows from companies like Milgard or Andersen. These windows help to keep the heat out. Every ADU we build meets or goes beyond the Phoenix building codes. This makes sure the ADU is strong and energy efficient.

FAQ

Frequently Asked Questions

Building an ADU project in Phoenix, Arizona, usually takes between 8 to 12 months from when we start designing to when the final inspection is done. This timeline includes 2 to 4 months for getting the architectural design ready and getting permits from the City of Phoenix. After that, the construction itself typically takes 6 to 8 months to complete. There are a few things that can change this ADU timeline in Phoenix. The complexity of the ADU design is one factor. How easy it is to get to the building site also matters for the ADU construction. The speed of city departments in Phoenix when they review plans and issue permits can also affect the overall ADU project schedule. Phoenix ADU Solutions, Inc. manages each phase of the ADU project proactively to help keep things on track. For Phoenix homes, Phoenix ADU Solutions, Inc. is here for all your ADU needs.
In Phoenix, ADUs are allowed in residential zones like R-1, R-2, and R-3. This is true as long as the ADU meets the specific rules in the Phoenix Zoning Ordinance, Chapter 6. These rules usually cover things like the minimum size your lot needs to be for an ADU. They also include setback requirements, which means how far the ADU must be from your property lines. For example, it might need to be 5 feet from the side and rear property lines. There are also maximum ADU size limits in Phoenix. These limits are often based on the size of your main house or a set square footage, like 750 to 1000 square feet. Phoenix ADU Solutions, Inc. checks all the current zoning regulations for your specific property during our first assessment. These rules are important because they affect the design and if an ADU can even be built on your lot in Phoenix.
For ADUs in Phoenix, a Post-Tension Slab-on-Grade foundation is often the best choice. This is because of the expansive clay soils we have here in the Phoenix area. This type of foundation uses strong steel cables to keep the concrete compressed. This means the concrete resists cracking and movement. The soil in Phoenix can expand and contract, and a Post-Tension Slab-on-Grade foundation handles this better than a regular slab. Phoenix ADU Solutions, Inc. also looks at Drilled Pier foundations for sites that have big changes in grade or very problematic soils. This helps make sure the ADU has long-term structural stability in Phoenix.
ADUs in Phoenix are built with specific strategies to deal with the extreme summer heat. We start with good insulation. Phoenix ADU Solutions, Inc. typically uses R-21 wall insulation. This R-21 wall insulation is often batt insulation or blown-in cellulose insulation. We also use R-38 attic insulation, which can be blown-in fiberglass insulation or blown-in cellulose insulation, to make a solid thermal envelope. High-efficiency HVAC systems are standard for our ADUs in Phoenix. These HVAC systems have SEER ratings of 16 or higher. We also put in features like radiant barriers in the attic. Light-colored roofing materials are used for ADUs in Phoenix. We also use strategically placed overhangs to shade windows. These things together help to lower the cooling loads a lot. Phoenix ADU Solutions, Inc. provides ADU construction services for homes in Phoenix, AZ.
An ADU can increase your property value in Phoenix, AZ. This often gives a strong return on investment for homeowners in Phoenix. An ADU adds usable square footage to a property in Phoenix, and it also increases rental income potential. An ADU offers flexible living arrangements for Phoenix homeowners. These things are all very valued in the current real estate market in Phoenix, AZ. Appraisals will often reflect the added value of a separate, fully functional living unit. This is especially true in desirable Phoenix neighborhoods where space is at a premium. Phoenix ADU Solutions, Inc. knows how to build an ADU that adds value to your Phoenix home.
