California ADU Grant Program
California ADU Grant Program: how to apply (when it's funded).
CalHFA's ADU Grant Program offers up to $40,000 to reimburse pre-development and non-recurring closing costs for qualifying California homeowners building an ADU. The grant is administered through CalHFA-approved lenders and covers soft costs like architectural plans, permits, soil tests, surveys, and energy reports. Below is how it works — and an honest read on current funding status.
How it works
A non-repayable grant from the California Housing Finance Agency (CalHFA) that reimburses pre-development costs associated with ADU construction. The grant is income-restricted (historically tied to 80% Area Median Income) and is administered through CalHFA-approved lenders, not directly by the agency.
- Rate range
- N/A — grant, not a loan
- Loan amount
- Up to $40,000 reimbursement

- Best for
- Low- and moderate-income California homeowners planning an ADU. Particularly valuable for homeowners whose budget is otherwise tight around the soft costs.

- 03Identify a CalHFA-approved lender — these are listed on CalHFA's ADU Lender page
- 04Submit application through the lender along with income docs, property docs, ADU plans, and contractor info
- 05Lender disburses approved funds to reimburse pre-development costs against receipts (architectural plans, permits, soil tests, surveys, energy reports)

- Income limits exclude many homeowners
- Reimbursement-based — you pay first, get reimbursed against receipts

FAQ
- Is the California ADU Grant Program currently funded?
- As of May 2026, no. Per CalHFA's official ADU page, the latest round of funding was fully allocated on December 28, 2023. CalHFA has not announced a new funded round since. Treat the grant as paused until and unless the agency publishes a new round.
- How much does the California ADU Grant cover?
- Up to $40,000 in pre-development costs: architectural designs, permits, soil tests, impact fees, property surveys, and energy reports. The grant doesn't cover hard construction costs (framing, MEP, finishes); that's funded through your construction loan, HELOC, or other product.
- What income limits apply?
- CalHFA's income limits are county-specific and updated periodically. Historically the program has been tied to 80% Area Median Income. Check the current limits at calhfa.ca.gov/homeownership/limits/income/limits-adu.pdf when the program is funded.
- Can I apply for the grant directly with CalHFA?
- No — CalHFA administers the grant through approved lender partners. You apply through a CalHFA-approved lender, who then processes the grant alongside your loan. Anyone claiming they can 'apply on your behalf' for a fee is operating a scam pattern that CalHFA has explicitly warned about.
