California FHA Loan Limits by County: The Math That Decides Whether You Can Buy in San Francisco vs Fresno

Which California County Sets Your Actual FHA Ceiling?

California’s 58 counties split into three FHA loan limit tiers for 2026, and which one applies depends entirely on where you’re buying, not what you earn. Fresno County sits at the $524,225 national floor. San Francisco County sits at the $1,209,750 national ceiling. Everything in between falls into a mid tier set county by county against local median home prices, per HUD’s county loan limit lookup tool.

Why California FHA Buyers Almost Always Need Down Payment Assistance Layered On Top?

Most California FHA buyers cannot self-fund even the reduced 3.5% down payment once the county tier pushes the loan amount into six figures, which is why assistance programs that can pair with FHA get used far more often than in lower-cost states. Assistance is a deferred, no-monthly-payment second mortgage of up to 3.5% of the purchase price, due when the home sells, refinances, or is paid off. Assistance works the same way structurally but caps at 3% and is written only against conventional first mortgages, not FHA, so it is not the layer FHA buyers reach for.

In Alameda County, sitting inside the $1,209,750 high-cost tier, a $950,000 purchase needs $33,250 down at FHA’s 3.5% minimum. Assistance’s 3.5% ceiling on the same purchase price contributes exactly that amount as a deferred second, effectively covering the entire minimum down payment with no cash due at closing beyond the buyer’s own closing-cost reserve. In Riverside County, sitting in the mid tier around $573,500, a $480,000 purchase needs $16,800 down, and assistance’s 3.5% ceiling again covers it in full, just at a smaller dollar figure because the county tier is lower.

The tradeoff is income limits, which swing hard by county. For 2026, Los Angeles County’s income limit sits at $174,700, while Fresno County’s sits at $103,900.A high-earning Bay Area tech household can price itself out of state and local down payment assistance programs entirely even while sitting well inside the FHA loan limit for their county.

How Do FHA Rules Handle California-Specific Property Types (ADUs, Condos, TIC)?

California’s housing stock includes several property types that create real friction with FHA underwriting, and buyers who don’t plan around them lose contracts. FHA condo approval is the biggest bottleneck: only about 2,300 condo projects statewide currently carry FHA approval, against a far larger inventory of HOA buildings, which means dense condo markets in San Francisco and Los Angeles routinely produce contracts on unapproved buildings that cannot close FHA at all.

Accessory dwelling units work in the buyer’s favor since a 2024 HUD rule change: FHA now counts a portion of documented or projected ADU rental income toward qualifying income, which matters in a state where ADU-friendly zoning laws have made backyard units common in Los Angeles, Sacramento, and the East Bay. Tenancy-in-common ownership, the fractional undivided-interest structure used as a condo alternative in dense San Francisco neighborhoods, is not financeable with FHA at all; TIC buyers need a specialized conventional or portfolio TIC loan instead.

Mello-Roos special tax assessments, common on newer subdivisions built under California’s 1982 Community Facilities District law, get folded into the property tax line of the FHA debt-to-income calculation, which can shrink the loan amount a buyer qualifies for compared to an older neighborhood without one.
