Overview for ADU conversions
Converting part of your property to an ADU lets you create a separate living space with its own entrance, kitchen, and bathroom. These pages show you the steps to get permits for an ADU conversion. For information on building a new, separate structure, see our page on new, detached ADUs.
Here's an overview of what you'll need to convert all or part of an existing structure to an ADU.
