Frequently Asked Questions

What is an ADU and can I build one on my property?

Do you handle ADU permits and plans?

Yes. We manage design, permitting, and construction, and coordinate with local building departments across Marin, Sonoma, and the Bay Area.

How much does it cost to build an ADU in the Bay Area?

ADU costs vary with size, type (attached, detached, or garage conversion), and finishes. We provide a detailed estimate covering materials, labor, and timeline before work starts.

Does an ADU add value to my home?

An ADU can increase property value and provide rental income or space for family. It is one of the most effective ways to add usable square footage in the Bay Area.
