Arizona law allows up to two ADUs per single-family lot, giving Phoenix homeowners flexibility in how they house extended family. A detached casita sits privately in your backyard, close enough for peace of mind yet separate enough to preserve dignity and independence. This is aging-in-place done right. On your property, surrounded by family.

AzADU casitas aren't modular boxes dropped in a backyard. They're stick-framed on a permanent slab-on-grade concrete foundation, built to the same structural standard as a primary residence. Dimensional architectural shingles with UV-resistant properties cap the roof, while gutters manage Arizona's intense monsoon runoff. Every unit is a real investment and it's protected like one.

The magic of a detached structure is the psychological and acoustic separation it creates. When you walk across your backyard and step through that door, you're leaving the noise of the household behind. That mental shift is real, and it makes every session more intentional.

Imagine a detached guest casita positioned right off the pool deck, large sliding glass doors that blur the line between indoor cool and outdoor fun. Step in, dry off, mix a drink, and step back out without ever cutting through the main house. No wet footprints on your hardwood floors. No guests wandering through the kitchen throughout the night.

Some families are navigating aging parents who need proximity but cherish their privacy. Others are watching adult children struggle with housing costs and want to offer a soft landing without turning the family home into a crowded dormitory. An accessory dwelling unit — a fully independent living space on your existing property — addresses both with grace.

Most Phoenix homeowners assume building a backyard casita means years of waiting, stacks of paperwork, and an endless loop of city back-and-forth. The reality — when you have the right partner and the right plan — is a structured, eight-month journey from first site visit to handing over the keys. Here's exactly how AzADU makes that timeline achievable.
