Building an ADU is one of the most expensive projects most homeowners take on, and the information is scattered and marketing-heavy. In February 2026 I built ADU Builder Hub, a directory of Los Angeles ADU builders with a consistent listing format, a taxonomy for services, location, and scope, and a referral model for architects, designers, and sponsored planning guides. Other California cities are being added.
