About California ADU Pros

California ADU Pros is a directory built specifically for accessory dwelling unit (ADU) projects across California. California's ADU laws have made backyard rentals and multi-generational housing far more accessible than they used to be, but finding a contractor who knows local permitting inside and out is still the hardest part of the process.

We list contractors whose California contractor's license is active and in good standing, verified against the California Contractors State License Board's (CSLB) public data. We don't accept payment in exchange for hiding license issues, and we never fabricate reviews or ratings — every fact shown about a contractor on this site comes directly from public CSLB records.

Homeowners use California ADU Pros to compare contractors by city and request free quotes. Contractors interested in being listed can reach out via List Your Business.
