"Ernesto and his crew built our ADU from the ground up. They handled every permit, kept us posted the whole time, and finished on schedule. We're renting it for $1,400/month now. Best investment we've made."

Questions & Answers

Common questions
about ADUs & remodels.

For full cost breakdowns and the permit process, see our cost and permit guides.

An ADU (Accessory Dwelling Unit) is a secondary housing unit on a single-family lot — detached or attached. A "guest home" or "casita" is typically a smaller detached unit for guests or family. Both require permits, meet zoning requirements, and add significant property value.
ADU costs in the Tucson area typically range from $120 to $250 per square foot depending on size, finish level, and site conditions. A 600–800 sq ft unit generally runs $90K–$200K. We'll give you a detailed estimate after your free site consultation.
From signed contract to move-in, plan for 4–8 months: 1–2 months for design and permitting, 3–6 months for construction depending on scope. We give you a clear timeline upfront and communicate any changes in real time.
