Adu permit — Phoenix, AZ
Last updated: September 24, 2026
What affects the price
Building an ADU involves several moving parts that shape your total budget. The biggest factor is whether you choose a prefabricated unit or a custom build on-site. Site preparation is also significant; if your land requires extensive grading, utility trenching, or foundation work, costs will climb. Your choice of finishes—like kitchen cabinetry, flooring, and siding materials—also shifts the bottom line. We help you navigate these variables to find a setup that fits your property. Exact pricing confirmed free on the call.
About this service
Obtaining an ADU permit is the legal process of getting approval from your local planning department to build or convert a secondary living space. You need this to ensure your project complies with safety codes, setbacks, and neighborhood density regulations. Skipping this step can lead to significant legal issues or problems when you try to sell your home later. Permit fees are influenced by your city’s requirements and project size. Exact pricing confirmed free on the call.
