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. Ask your designer and community for recommendations of good local professionals and make a list of candidates. It’s great if they have ADU experience, but it’s not necessary.
First, you’ll solicit bids. You will want to get at least three bids for comparison. When you have bids, you can begin selecting your contractor.
Before you hire a contractor, make sure to check their license and insurance and when they present you with a contract, review everything carefully.
