Cities in San Mateo County

Local housing costs

HUD’s fair market rent for San Mateo County sets what a housing voucher covers here. It is a useful floor for what local housing costs, not a price for care.

One-bedroom fair market rent (FY2026)
$2,977per month
Two-bedroom fair market rent (FY2026)
$3,604per month
Income limit, one person (FY2026)
$73,550per year
Income limit, four people (FY2026)
$105,050per year

The income limits are HUD’s very low income threshold, about 50 percent of area median income. They are the line most Section 8 and income-restricted senior housing programs use. HUD publishes a one-person and a four-person figure, so households of two or three fall between the two numbers above.
