One request, matched to contractors who actually work in your area
Building an accessory dwelling unit (ADU) in California means navigating permits, contractor licensing, cost estimates, and a construction trade you may only deal with once. California ADU Network exists to shorten that first step: tell us about your project once, and we route your request to licensed ADU contractors in our vetted network who serve your part of California.
Matched, not searched
Skip the endless directory scrolling. Submit your project details once and we route them to contractors who actually build ADUs in your region.
Licensed contractors only
Every contractor in our network holds an active California contractor license for the work they perform. We verify licensing before a contractor joins the network.
Learn before you commit
Our Research Center breaks down permits, cost factors, and ADU types in plain language, so you walk into your first contractor conversation prepared.
Connecting homeowners across California
Our contractor network has the deepest coverage in four regions where ADU demand is highest: the Bay Area, San Diego, Sacramento, and Los Angeles. We route requests statewide, but these are the regions where our vetted network currently has the most active, licensed ADU builders.
Popular ADU project types
Homeowners come to us comparing detached vs. attached ADUs, exploring a garage conversion, or pricing out a prefab ADU. Whatever stage you're at, our network can route your request to a contractor who has built that exact type of unit.
What to have ready
Before you request a match, it helps to know your lot size, whether you want a detached or attached unit, and your rough budget range. Not sure yet? Start with our ADU basics guide and our cost factors breakdown.
