ADUs in Anaheim

Anaheim has one of the fastest ADU paths in Orange County: choose a pre-approved design, and a qualified home can complete review in a few days.

What applies to your lot

Building an ADU in Anaheim

Who approves your ADU

City of Anaheim: Planning and Building review ADUs, with a standard path and the ADU Express path. State law applies everywhere: a decision within 60 days of a complete application, no public hearing, and at least 800 sq ft with 4 ft side and rear setbacks.

ADU Express

With a pre-approved detached ADU from the city catalog, qualified single-family properties can complete the ADU review in 1 to 3 days, according to the city.

A pre-approved catalog

Each plan set in the catalog lists the extra reports or documents needed for a full submittal, so nothing is a surprise.

Standard path when needed

If your lot does not qualify for ADU Express, or you want a custom design, the standard review still applies, within the state 60-day limit.
