If you are hunting for a one-bedroom apartment in the Bay Area, the gap between the cheapest and priciest cities is now nearly $3,000 a month, according to the October 2026 San Francisco Bay Area metro report from the rental site Zumper.
The least expensive cities
Vallejo came in as the most affordable city in the report, with a median one-bedroom asking rent of $1,560. Antioch was second at $1,690, and Concord was third at $1,860. All three are in the outer East Bay or North Bay, well away from the job centers of San Francisco and Silicon Valley.
The most expensive
San Francisco topped the list at a median $4,400 for a one-bedroom. Mountain View followed at $3,630 and Palo Alto at $3,490, both close to big tech employers on the Peninsula.
Where rents climbed fastest
San Francisco also posted the biggest year-over-year increase in the report, 25.4%. Emeryville was next at 22.7%, and Campbell rose 17.9%. Over a single month, San Mateo saw the largest jump, at 6%.
What the numbers mean
Zumper's figures are median asking rents drawn from its listings, so they reflect what landlords are advertising for open units rather than what current tenants pay. Renters already in a unit covered by local rent control may see much smaller increases. Still, the report shows how sharply the cost of moving has diverged across the region. A renter leaving a typical San Francisco one-bedroom for one in Concord would be looking at about $2,540 less in monthly asking rent.
Concord renters looking for help can reach the city's housing division at (925) 671-3152 for tenant counseling and affordable housing waitlist information, according to the Concord Chronicle.
