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.

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.
