Everything you need to build an Accessory Dwelling Unit in California. Check your property to learn your zoning requirements, estimate costs, and design your ADU. Then, apply for permits and meet local professionals who can help from start to finish on the ADU Marketplace.
Planning to convert your garage or use your backyard to add an in-law unit? The State of California has passed new legislation (SB 1069 and AB 2299) which gives homeowners the right to build Accessory Dwelling Units (ADUs) on most single family properties, effectively doubling the housing potential of these residences.
Building a new ADU or converting existing space can be a smart investment for many homeowners in California. Adding living space, appreciating property value, generating rental income and helping solve the housing crunch, one unit at a time are just a few reasons that building an ADU can be an excellent move.

Transform an existing secondary structure. Building on top of a garage is an option in certain areas too.
