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.

Multi-generational living is making a serious comeback in Phoenix and for very good reasons. Whether it's aging parents who want independence without isolation, adult kids stretching a tight housing budget, or grandparents who've basically become the best free childcare in the neighborhood, the logic is hard to argue with. But the key word is independence.

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.
