The short version: three numbers decide whether a first-time buyer in California gets help: the program’s own cap, HUD’s income limit for the metro, and the FHA loan limit for the county. This page puts all three beside what a two-to-four-unit home costs in each California metro, because a duplex you live in is the one purchase where the rent from the other unit counts toward qualifying.
The statewide program in California
The full 83-metro survey, with the programs that failed the two-to-four-unit test, is on the down payment assistance page.
Income limits for assistance in California, by metro
Why the limit moves: HUD sets a median family income for every metro each year and most programs cap eligibility at 80% of it. The published 80% figure is adjusted, so it is not always exactly 80% of the median. The same salary can qualify in one California metro and miss in the next.
| Metro | Area median income (4 people) | HUD 80% limit (4 people) | HUD 80% limit (1 person) |
|---|---|---|---|
| Bakersfield, CA | $81,900 | $77,700 | $54,400 |
| Fresno, CA | $91,300 | $77,700 | $54,400 |
| Los Angeles, CA | $108,100 | $133,250 | $93,300 |
| Oxnard, CA | $135,600 | $125,600 | $87,950 |
| Riverside-San Bernardino, CA | $106,500 | $98,400 | $68,900 |
| Sacramento, CA | $124,000 | $105,100 | $73,600 |
| San Diego, CA | $130,900 | $139,900 | $97,950 |
| San Francisco, CA | $200,800 | $168,100 | $117,700 |
| San Jose, CA | $205,500 | $162,400 | $113,700 |
What a duplex costs in California, and the income it takes
The part most buyers miss: in every California metro surveyed the income needed for the typical duplex sits above the four-person 80% limit, so the program reaches cheaper buildings than the median one. The income figure is FHA’s 31% front-end guideline on the typical duplex at 6.71% with 3.5% down, before the 75% rent credit a lender applies to the second unit.
| Metro | Duplex entry price | Typical duplex | Income needed (31%) | Versus the 80% limit (4 people) |
|---|---|---|---|---|
| Bakersfield, CA | $370,000 | $450,000 | $153,343 | over |
| Fresno, CA | $399,000 | $544,900 | $180,142 | over |
| Los Angeles, CA | $790,000 | $975,000 | $315,918 | over |
| Oxnard, CA | $829,000 | $999,000 | $315,277 | over |
| Riverside-San Bernardino, CA | $559,990 | $629,888 | $194,641 | over |
| Sacramento, CA | $545,000 | $688,000 | $224,271 | over |

| San Jose, CA | $1,250,000 | $1,425,000 | $461,904 | over |
FHA loan limits in California for 2026
An FHA loan, the 3.5%-down loan most first-time buyers use, caps the loan by county and by unit count. The two-, three- and four-unit limits are higher than the single-family limit, which is why a duplex can be financed with the same small down payment at a higher price.
| Metro | 1 unit | 2 units | 3 units | 4 units |
|---|---|---|---|---|
| Bakersfield, CA | $541,287 | $693,050 | $837,700 | $1,041,125 |
| Fresno, CA | $541,287 | $693,050 | $837,700 | $1,041,125 |
| Los Angeles, CA | $1,249,125 | $1,599,375 | $1,933,200 | $2,402,625 |
| Oxnard, CA | $1,035,000 | $1,325,000 | $1,601,600 | $1,990,450 |
| Riverside-San Bernardino, CA | $690,000 | $883,300 | $1,067,750 | $1,326,950 |

Questions people ask about buying a first home in California
Does GSFA Platinum allow a duplex?
GSFA Platinum was usable on a two-to-four-unit home when checked in July 2026: it offers up to 5.5% of the first mortgage loan amount to eligible owner-occupant buyers, and the building has to be one you live in. Program terms change, so confirm on the program page before you write an offer.

The income limit most California assistance programs use is HUD’s 80% area median income figure for the metro, which for a four-person household is $77,700 in Bakersfield and $168,100 in San Francisco for FY2026. Smaller households get a lower figure; $54,400 for one person in Bakersfield.
