ADU Grant Program

The ADU Grant provides up to $40,000 to reimburse pre-development and non-reoccurring closing costs associated with the construction of the ADU. Prevelopment costs include site prep, architectural designs, permits, soil tests, impact fees, property survey, and energy reports.

What is an ADU?

Accessory Dwelling Units (ADUs) have been known by many names: granny flats, in-law units, backyard cottages, secondary units and more. No matter what you call them, ADUs are an innovative, affordable, effective option for adding much-needed housing in California.
