How do I find a contractor/builder?

If you are not using a design/build firm, you will need to find a builder or contractor to take over for the construction phase of your ADU.

First, you’ll solicit bids. See our Guidebook for more details on what you want to see in a bid, what other documentation to collect from potential builders, and what to look for in your bidding candidates. Builders with ADU experience can be a plus, but shouldn’t be an absolute requirement since building an ADU is often similar to other small residential construction. You will want to get at least three bids for comparison.

When you have bids, you can begin selecting your builder. See our Guidebook for more details on how to compare bids and choose the best option for you.

Before you hire a builder, make sure to check their license and insurance. You can verify their license by calling the Contractors’ State License Board at (800) 321-2752 or check online at www.cslb.ca.gov.  You can verify insurance by requesting a certification of insurance or by calling their insurance agent. Make sure workers’ compensation, property damage, and liability are included.

When your contractor presents you with a contract, review everything carefully. See our Guidebook for more details on what the contract should specify, including payment plan details. Do not sign the contract until you fully understand and agree with all the terms.
