This directory lists 1,865 active, license-verified contractors with an office of record in the county — general builders (A and B) plus the licensed trades ADU projects use (C-10 electrical, C-36 plumbing, C-5 framing) — across 20 cities and communities.
Coastal-zone and hillside rules shape many South Coast projects, and each city — plus the county, for unincorporated areas — applies its own ADU standards under state law. Verify the license at CSLB, then check your jurisdiction's current ADU rules before you commit to a design.
