About ADU Builder Match
A directory and homeowner resource for finding, comparing, and learning about ADU builders, contractors, and permit professionals in San Diego.
Why this resource exists
Finding an ADU builder in San Diego is harder than it should be. Pricing ranges are wide and often unclear. Permitting rules vary by city and change frequently. Search results mix general contractors, real estate agents, and companies that built one ADU years ago with no information about what they actually specialize in today.
There is no straightforward way to compare what different companies do, which areas they serve, whether they handle permits, or what a project similar to yours would cost. Homeowners often spend weeks making calls before they have a clear picture of their options.
ADU Builder Match is built to address that. It is a directory focused on San Diego, organized around the information homeowners actually need: project types, service areas, company descriptions, and practical guides on cost and permitting. The goal is to make the comparison process faster and more informed, before you make any commitments.
Our mission
To make the ADU planning process more transparent and easier to navigate for homeowners, starting with San Diego and expanding across California.
That means publishing accurate, well-organized builder information, explaining costs and permitting in plain terms, and connecting homeowners with companies that match their project type and location.
