Garage renovations, explained

Everything to know before you talk to a contractor.

What counts as a garage renovation?

A basic conversion finishes the space into a bedroom, office, gym, or entertainment room — no plumbing involved, roughly $6,000–$33,000.

A full legal ADU conversion adds a kitchenette and bathroom so the space can be rented as a separate unit — a much bigger project, often $150,000+ in the Phoenix market once permitting and full ADU-grade construction are factored in.

Why Phoenix homeowners are doing this now

Rising housing costs, multigenerational living, and rental-income potential are all driving demand.

A 2024 Arizona law (HB 2720) set statewide minimum ADU approval standards, easing what used to be a heavier permitting process — though each city still layers its own rules on top.

What to ask any contractor

  • How do they handle permits?
  • What's the realistic timeline?
  • Are garage door/parking requirements preserved? (Some cities require it.)
  • How is HVAC handled given Phoenix summers?

What it typically costs

  • Basic conversion (bedroom, office, gym, entertainment room): roughly $6,000–$33,000
  • Full legal ADU (kitchen + bathroom added): often $150,000+ in the Phoenix market
