Is California ADU Network a licensed contractor?
No. California ADU Network is a homeowner referral and lead-routing service. We connect you with independent, licensed local ADU contractors in our vetted network. We do not perform construction, design, or permitting work ourselves.
Is there a cost to use California ADU Network?
Requesting a match is free for homeowners. You only pay the contractor you choose to hire, based on the bid and contract you agree to directly with them.
Are the contractors in your network licensed?
Every contractor in our network is required to hold an active, appropriate California contractor license for the work they take on. We verify licensing status before a contractor joins the network.
How much does an ADU cost to build in California?
Cost varies widely by region, size, site conditions, and finish level, so we do not publish a single flat number. Our ADU cost factors guide breaks down what actually drives your price, and a matched contractor can give you a real estimate for your specific property.
Do I need a permit to build an ADU in California?
Yes. ADU construction requires local building permits, even though California's statewide law (Government Code §65852.2) limits how restrictive local agencies can be. See our ADU permit process guide for the general steps.
What is the difference between a detached and attached ADU?
A detached ADU is a standalone structure separate from the main house. An attached ADU shares a wall with the primary residence. Our detached vs. attached ADU comparison covers the tradeoffs of each.
Can I convert my garage into an ADU instead of building new?
Yes, garage conversions are one of the most common and often most cost-effective ADU paths in California, since the structure and foundation already exist. See our ADU vs. garage conversion guide.
What areas does your contractor network cover?
We route requests statewide, with the deepest contractor coverage currently in the Bay Area, San Diego, Sacramento, and Los Angeles. Visit Areas We Cover for details, or request a match and we will confirm coverage for your specific location.
How long does it take to get matched with a contractor?
Most homeowners hear from a matched contractor within a few business days of submitting a request, though timing can vary depending on current contractor availability in your area.
What if I am not sure whether I even want an ADU yet?
That is a normal place to start. Our ADU basics guide and the rest of our Research Center are built for homeowners who are still exploring options before talking to a contractor.
