The San Francisco Bay Area need for additional housing is no secret. The region’s high cost of living and lack of available housing inventory have made it difficult for many people to find a place to call home.

One solution that has gained popularity in recent years is the construction of accessory dwelling units (ADU). ADU are small, standalone units that can be built on a property with an existing dwelling. They are often used as rental units, in-law units, or home offices.

The construction of ADU is not a simple process, and it is important to hire a reputable and experienced builder to ensure the project is completed successfully. This guide will provide you with some tips on how to hire an ADU builder in the San Francisco Bay Area.

Research ADU Builders

Start by researching ADU builders in the San Francisco Bay Area. Check out online directories such as ADU Contractors, Houzz, and Yelp. Look for builders who specialize in ADU and have experience in building similar projects. Check their reviews and ratings to see what their past clients have to say about their work.

Check their Credentials and Licenses

It is important to ensure that the builder you hire has the necessary licenses and credentials to work on your ADU project. Check if they have a valid contractor’s license in California and insurance coverage. You can also ask for references from past clients to check their work quality.

Understand the Timeline

Ask the builder to provide a timeline for the completion of the project. It is important to have a clear understanding of how long the project will take and when it will be completed.

Schedule a Consultation

Contact the builders you have shortlisted and schedule a consultation. During the consultation, discuss your ADU project and what you are looking for in terms of design and functionality. A good builder should listen to your needs and provide insightful ideas on how to make the most of your space and resources.

Compare Quotes

Compare the quotes from different builders and evaluate them on key factors such as price, timeline, quality of materials, and experience. Make sure to choose a builder who is transparent and provides a clear understanding of the work they will be doing.

Sign a Contract

Once you have chosen a builder, review the contract carefully, and make sure that it covers all the terms you discussed. Ensure that the contract includes details such as start and completion dates, payment schedule, warranties, and any other relevant details.


By following these tips, you can hire an experienced and reputable ADU builder in the San Francisco Bay Area to construct your new unit. This can help alleviate the housing shortage and provide you with a valuable addition to your property.
