Homeowners across California are asking the same question: is the $40,000 incentive from the CalHFA ADU Grant Program still available in 2026? The short answer is no. ADUs have grown from roughly 1,300 annual permits statewide in 2016 to over 30,000 in 2024, now accounting for more than a quarter of all new homes permitted in California. This guide explains what happened to the grant program behind that growth, what it originally covered, and the financing options that now fill the gap it left behind.
Is the CalHFA ADU Grant Program Still Available in 2026?
No. The CalHFA ADU Grant Program’s most recent funding round was fully allocated on December 28, 2023. As of 2026, the program is not accepting new applications, and the California Housing Finance Agency has not announced a relaunch date.
Homeowners should treat any claim of guaranteed access to this grant with caution. CalHFA has publicly stated that no new funding round is currently open, and the safest way to confirm current status is directly through CalHFA’s ADU program page, not a third party.
To verify current status yourself, check two official sources directly: CalHFA’s ADU program page and the California Department of Housing and Community Development’s ADU funding page. Both are updated when a new round opens, and CalHFA also offers an email signup for program status changes. Relying on a contractor’s marketing page or an older blog post to confirm eligibility is a common mistake, since that content is not always kept current.
Why Official Sources Seem to Disagree
Part of the confusion comes from HCD’s own website, which still describes the CalHFA ADU Grant Program in present tense, as if it were an open, available source of up to $40,000. HCD’s own updated ADU Handbook, published in March 2026, states plainly that the funds had been exhausted at the time of writing, and reporting has quoted a CalHFA spokesperson confirming no new money was allocated for 2026.
The safest way to read this is that HCD’s funding page works more like a directory of funding pathways than a real-time availability tracker, and the same pattern shows up in several local program listings on that page. This is exactly why homeowners should verify a specific program’s status directly with that program, rather than trusting any single funding directory at face value.
What the CalHFA ADU Grant Program Covered
When it was active, the program reimbursed eligible homeowners up to $40,000 for pre-development costs tied to building an ADU. These pre-development costs included architectural design and permits, soils testing and site surveys, and other non-recurring closing costs required before construction could begin. The grant never covered actual construction costs.
Eligibility depended on property ownership requirements and income limits and AMI, since the program specifically targeted moderate-income households. In most cases, the home also had to serve as a primary residence ADU project, not a second home or a purely investment property.
One nuance is easy to miss. The former grant required an owner-occupied single-family home on the lot, but that was a program-specific rule, not general California ADU law. Under current state law, local agencies generally cannot impose their own owner-occupancy requirements on ADUs, except in limited cases involving ADUs sold separately from the primary home.
Why the CalHFA ADU Grant Program Paused
The program launched in 2021 with grants of up to $25,000 per household, and demand exhausted that initial funding quickly. A second phase followed in 2023, raising the grant amount to $40,000 and adding roughly $100 million in new funding statewide. That phase also filled fast, reaching full allocation by December 28, 2023.
Unlike a permanent fee exemption, this program depends on a specific legislative or budget allocation each time it runs. No new allocation has been approved as of 2026, which is why the program remains closed rather than simply slow to process applications. State-level rules like the impact fee exemption still apply everywhere in California, whether you work with an ADU builder Los Angeles homeowners recommend or an ADU builder Sacramento residents use.
How Much Does an ADU Cost Without Grant Assistance?
Understanding overall project cost helps put financing choices into perspective. A basic ADU conversion, such as a garage converted into a studio, often costs $75,000 to $150,000 in the Los Angeles area. Detached, ground-up ADUs with a full kitchen and bathroom typically run higher, often $150,000 to $250,000 or more, depending on size and finish level.
Pre-construction soft costs, including architectural design and permits and soils testing and site surveys, typically represent 10 to 15 percent of total project cost. That is roughly the same range the CalHFA grant used to cover directly. Without that assistance, homeowners now fold these costs into whichever financing option they choose, whether that is a HELOC, a cash-out refinance, or a construction loan.
Alternative Financing Without a Grant: Your ADU Financing Options
Alternative financing without grant funding is now the standard path for most homeowners. Each option below fits a different financial situation, so comparing more than one lender is worth the time before committing.
Home Equity Financing (HELOC)
A home equity line of credit, often called a HELOC, lets homeowners borrow against the equity already built up in their primary home. This option works well for homeowners who have owned their property for several years and have significant equity available. Interest rates on a HELOC are usually variable, so payments can shift over time.
Cash-Out Refinance for ADU
A cash-out refinance replaces your existing mortgage with a new, larger one, and you receive the difference in cash to fund construction. This route can make sense when current mortgage rates are competitive, though it resets your loan term and may increase your monthly payment. One important note: FHA rental income from an ADU cannot be used to help qualify for a cash-out refinance transaction, even though it can be used for other loan types.
Construction Loans
Construction loans are built specifically for ADU construction, releasing funds in stages as work is completed rather than all at once. These loans typically convert into a standard mortgage once construction finishes. They tend to require more documentation upfront, including detailed plans and contractor estimates, but they align payments with actual project progress.
Interest Rate Buydowns
Some lenders offer interest rate buydowns, where the borrower pays an upfront fee to secure a lower rate for a set period, or sometimes for the life of the loan. This can lower monthly payments significantly during construction and the early years of the loan. Ask your lender whether a temporary or permanent buydown fits your specific ADU project better.
Which Financing Option Fits Your Situation?
Homeowners with significant equity and a lower risk tolerance often start with a HELOC, since it does not touch their existing mortgage rate. Cash-out refinancing becomes more attractive when current rates are close to or better than your existing mortgage rate, since the whole loan gets restructured anyway.
A construction loan tends to suit larger, more complex ADU projects, since funds release in stages tied to inspections. Interest rate buydowns pair well with any of these three options when a homeowner wants predictable payments during the first few years of a new loan.
Using Rental Income to Qualify: FHA Rental Income Qualification
FHA Mortgagee Letter 2023-17 changed the rules for many California homeowners. Under this policy, lenders can count a portion of actual or projected long-term rental income from an ADU toward a borrower’s qualifying income on an FHA-insured mortgage, for purchases, renovations, and new construction that includes one.
Rental income is generally capped at a percentage of total qualifying income, and lenders typically use half of the projected market rent if there is no rental history yet. This rule does not apply to cash-out refinance transactions, so confirm which loan type your lender is discussing. Lenders also want a signed lease or an appraiser’s market rent estimate, so keeping that documentation ready speeds up underwriting.
One distinction worth knowing: California law allows local agencies to require ADUs to be rented for terms longer than 30 days, and Junior ADUs cannot be used as short-term rentals at all. An ADU can be a genuine long-term rental income strategy, but state law does not treat it as a vacation-rental play.
ADU Permit Fees and the Impact Fee Exemption
ADU permit fees are a separate cost from local development impact fees, and the two are easy to confuse. Permit fees cover plan check and inspection services, and those still apply regardless of ADU size.
Impact fees are different. Under California Gov Code Section 66329, ADUs of 750 square feet or less are exempt from local development impact fees entirely. Larger ADUs are only charged impact fees proportional to their size relative to the primary home, never the full amount a new single-family home would owe. This exemption applies automatically under state law, with no application and no income limit attached.
City plan-check and permit processing fees are separate from this exemption and still apply regardless of ADU size. When budgeting, it helps to itemize these two categories separately from the start, since conflating them tends to produce an inaccurate early budget.
Local ADU Programs in Los Angeles and Beyond
Local ADU programs Los Angeles residents can access are fragmented rather than a single statewide source, and that is true across California in 2026, not just locally. Several counties and cities currently run their own financing or technical-assistance programs, though details and open status shift often enough that each should be verified directly before you rely on it.
- San Diego’s Housing Commission runs an ADU Finance Program offering construction loans up to $250,000 plus no-cost technical assistance, with a requirement that rents stay affordable for seven years
- Santa Cruz County’s ADU Incentives Program, run with Hello Housing, provides free project-management and feasibility support rather than direct cash
- San Mateo County’s One Stop Shop offers no-cost design, permitting, and project-management support for homeowners in specific participating cities
- Self-Help Enterprises coordinates ADU financing across several Central Valley counties using a mix of state funding streams
Not every listed program is currently open. Habitat for Humanity’s Monterey Bay ADU financing option, for example, is not accepting applications right now, even though it still appears on some funding directories.
A word of caution on other state-level funding names you may come across, like CalHome, the Local Housing Trust Fund program, REAP, or CDBG. These generally flow to local public agencies and nonprofits, not directly to individual homeowners through a simple application.
Los Angeles does not currently have a direct-cash homeowner grant comparable to San Diego’s program, but state law requires every California city to offer preapproved ADU plans and to approve or deny certain applications using those plans within 30 days. It is worth asking a Los Angeles-area contractor whether your city currently offers this.
Pre-Construction Soft Costs to Budget For
Even without grant funding, homeowners should budget for pre-construction soft costs early in the planning process. Architectural design and permits, soils testing and site surveys, structural engineering, and energy compliance documentation typically fall into this category.
These soft costs commonly run several thousand dollars before construction ever begins, and they are the exact category the CalHFA grant used to cover. Since that funding is currently unavailable, building these costs into your overall construction loan or HELOC draw from the start helps avoid a funding gap partway through design.
A detailed pre-construction budget also makes it easier to compare quotes from different contractors. Two bids that look similar on the surface can differ significantly once soft costs are itemized separately from actual construction labor and materials.
