What a voucher pays here
The voucher doesn't pay the FMR itself. It pays the payment standard. Housing authorities set it anywhere from 90% to 110% of FMR, which puts a two-bedroom standard in Contra Costa somewhere between $2,525 and $3,086. The tenant pays roughly 30% of their income, the voucher covers the rest up to the standard, and the PHA won't approve a rent above what comparable unassisted units get.
$2,805 a month is affordable, by HUD's 30% rule, on an income of roughly $112,200 a year. Put another way, $54 an hour full time.
Worked example for a two-bedroom renting at the payment standard. The tenant pays 30% of monthly income and the voucher covers the rest.

About this rate
Fair Market Rent is HUD's estimate of what a modest, decent unit rents for in an area, utilities included. It's set once a year and runs October to September. For FY 2027 that's October 1, 2026 through September 30, 2027. In Contra Costa, that runs from $2,088 for a studio up to $4,250 for four bedrooms, all five rates in the table above.
This is a metro rate. The county doesn't get one of its own. HUD lumps Contra Costa in with one other county in the Oakland-Fremont metro, Alameda County among them, and every one of them gets $2,805 for a two-bedroom. Where you are inside the metro doesn't change the county number. It does change the ZIP number, covered below.
Among California's 58 counties, Contra Costa ranks 14th for two-bedroom FMR. That's about 63% above the state median of $1,725 and about 164% above the national median county at $1,063. About 1,165,012 people live here, 9th in the state.
Rates by ZIP code
Zoom in and the picture changes. HUD's Small Area FMRs put a two-bedroom at $2,630 in 94509 (Antioch) and $3,650 in 94549 (Lafayette), with the 49 ZIP codes in between. Housing authorities in HUD-designated metros use those ZIP rates instead of the county rate. Everywhere else the ZIP numbers show where rents actually sit, and the county rate stays the official standard.
