Redwood City Rental Highlights
Redwood City keeps attracting renters on the strength of its central Peninsula location, revitalized downtown and proximity to major technology employers. Zillow reports rents up roughly
$800 against the prior year while classifying demand as warm. The pockets that lease fastest are Downtown Redwood City, Redwood Shores, Woodside Plaza, and the neighborhoods close to Caltrain and the 101 corridor, which appeal to professionals optimizing for commute time rather than square footage.
San Mateo Rental Highlights
San Mateo's market is similarly competitive, with average rents up roughly
$730 year over year. Transportation access plus a deep retail and dining base keep demand steady. Zillow currently reads San Mateo as cooler than Redwood City, but "cooler" here is relative: pricing still ranks among the highest in California, and available inventory is thinner in absolute terms (about 116 listings versus 168).
Why Are Peninsula Rents Still Rising?
Four forces continue to support rent growth, and none of them is on a short timeline.
- Strong employment centers. The Peninsula remains one of the most economically productive regions in the country. Even with hybrid work settled in, many professionals still pay a premium for proximity to offices, transit and urban amenities.
- Limited housing supply. Inventory stays constrained across much of San Mateo County. Development continues, but zoning requirements, land constraints, construction costs and long entitlement timelines keep new supply behind demand.
- High homeownership costs. Zillow reports median home values in Redwood City approaching
$1.9 million, which keeps would-be buyers renting for years longer than they planned.
- Quality of life. Downtown districts, dining, parks, schools and transportation infrastructure sustain demand from professionals, families and long-term residents alike.
For investors weighing this against cheaper entry points inland, our comparison of
East Bay versus Peninsula rental investment works through the yield tradeoff rather than the rent headline.
How Does Redwood City's Tenant Protection Ordinance Affect Landlords?
This is the most consequential change in the Peninsula market this year. Redwood City's
Tenant Protection Ordinance (TPO) took effect
January 1, 2026, with the stated purpose of promoting housing stability and reducing displacement.
What the Ordinance Covers
- Minimum lease terms. Landlords must offer prospective tenants the option of a one-year lease.
- Just-cause eviction protections. Protections attach when all tenants have occupied the unit for 12 months or more, or when one or more tenants have continuously occupied it for 24 months or more. The ordinance recognizes both at-fault causes (nonpayment, lease breach, nuisance, waste, criminal activity) and no-fault causes.
- Relocation assistance. No-fault terminations trigger mandatory relocation payments—typically calculated starting at four times HUD fair market rent or $12,000 (whichever is greater), with higher statutory adjustments or additional amounts required for lower-income, senior, or disabled tenant households.
- Right to return. Tenants displaced by a substantial remodel that requires them to vacate get the first opportunity to return once work is complete, at the same rent plus any increase state law allows.
Why This Matters Operationally
Three things change for owners. First,
relocation exposure is now a budget line, not a contingency: a no-fault termination in Redwood City starts at a five-figure payment in most cases. Second,
the right to return reshapes remodel economics, because you cannot assume a substantial remodel resets the unit to market rent with a new tenant. Third,
lease paperwork has to change, since the one-year offer requirement and the just-cause triggers both run off documented dates.
Review whether each property is covered, then align lease templates, notice procedures and recordkeeping with the ordinance before you need them. Our guide to
just-cause eviction in California covers how local overlays like this one interact with the statewide categories.
What Statewide Rent Rules Apply in Redwood City and San Mateo?
Neither city runs a traditional rent board, but local ordinances do not displace state law. Many landlords remain subject to California's
Tenant Protection Act (AB 1482).
- The rent cap. For covered properties, annual increases are limited to
5% plus the local Consumer Price Index, or 10%, whichever is lower, during any 12-month period. For increases taking effect
August 1, 2026 through July 31, 2027, that works out to
8.8% in San Mateo County.
- Exempt properties. Housing placed into service within the previous 15 years, certain owner-occupied properties, and some single-family homes meeting the exemption requirements may fall outside the statewide cap. The 15-year test is rolling, so verify it against the current year before implementing an increase.
Where the local ordinance is stricter than state law, the local standard governs. Our breakdown of
Bay Area rent increase limits shows how the calculation shifts across neighboring jurisdictions.
Which Rental Property Types Perform Best on the Peninsula?
- Single-family homes. Still the strongest draw for families who want space, a yard and access to well-regarded school districts. Longer tenancies reduce turnover cost and vacancy risk, which matters more than headline rent in a high-cost market.
- Condominiums and townhomes. Attract working professionals who want modern amenities and transit access, with a manageable maintenance profile.
- Multifamily. Provides income diversification and operating efficiency, and well-run buildings tend to hold occupancy because demand is deep.
- Accessory dwelling units. An increasingly common way for Peninsula homeowners to add rental income while the region works through its housing shortfall.

How Can Landlords Maximize Rental Income in 2026?
- Price to the current market, not last year's. Overpricing extends vacancy, which costs more than the premium you were chasing; underpricing leaves revenue on the table for the full lease term.
- Prioritize retention. Keeping a good tenant is materially cheaper than replacing one, and in Redwood City the relocation and right-to-return rules make turnover costlier still. Prompt maintenance, clear communication and fair renewals do most of the work. Our playbook on
reducing turnover and vacancy quantifies the tradeoff.
- Upgrade selectively. Updated kitchens and baths, in-unit laundry, energy-efficient appliances, smart home features and reliable connectivity are the features that support higher rents in this market.
- Stay compliant. Monitor both local and state housing regulation and update operating practice when it moves, rather than after a dispute surfaces.
