CA ADU Grant Program

CalHFA ADU Grant Program

A shortage of land, available homes for sale and rising housing costs can be a challenge for many homeowners who need extra space to meet the needs of their growing families or who could really use the extra rental income.

Accessory Dwelling Units (ADUs) – also referred to as granny flats, mother in-law units, multigenerational housing, backyard cottages, secondary units and more, are popular for a reason. ADUs provide an affordable option that can help meet the demands of much-needed housing in areas with limited land, often within the State of California. To make it easier for residents of California to invest in an ADU, the California Housing Finance Agency (CalHFA) has introduced an ADU grant program called the CalHFA ADU Grant Program.

The CalHFA ADU Grant Program seeks to provide more housing options in California by offering a grant to reimburse homeowners for the pre-development costs involved with the construction of the ADU.

The ADU Grant provides up to $40,000 towards pre-development and non-recurring closing costs/rate buy-downs associated with the construction and financing of the ADU. Predevelopment costs include site preparation, architectural designs, permits, soil tests, impact fees, property survey, utility trenching, land clearing and energy reports.
