Frequently Asked Questions
Can I build an ADU on any residential lot in Tucson?
It depends on your lot size, zoning, and setback requirements. We'll look at your property specifically before giving you a scope, since this varies parcel to parcel.
How is an ADU different from a garage addition?
An ADU is built as independent living space, with its own plumbing and electrical for a kitchen or bathroom if needed. A garage addition is built for vehicle or storage use, not full-time living.
Do you handle the permitting?
We coordinate the permitting process as part of the build. Requirements vary by jurisdiction, so this gets confirmed once we know your specific lot and plans.
