How do I find a contractor?

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

First, you’ll solicit bids. See our Workbook for more details on what you want to see in a bid, what other documentation to collect from potential contractors, and what to look for in your bidding candidates. You will want to get at least three bids for comparison. Typical construction costs for new, detached ADUs are between $400-$700 per square-foot as of July 2024.

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

See our Vendor Registry.

Before you hire a contractor, make sure to check their license and insurance and when they present you with a contract, review everything carefully. See our Workbook for more details.
