Santa Rosa, the largest city in Sonoma County and the North Bay's economic hub, has no local rent control ordinance — California's AB 1482 is the primary protection for eligible renters.·Updated May 2026

Key Takeaways
Most rentals with a certificate of occupancy issued 15+ years ago (generally pre-2011); single-family homes and condos are exempt under Costa-Hawkins
5% + Bay Area CPI (max 10% per year); approximately 8.8% for 2025
After 12 months of tenancy, landlords must cite a legally recognized at-fault or no-fault reason to evict
Santa Rosa sits at the heart of Sonoma County, roughly 55 miles north of San Francisco in the North Bay. With a population of about 178,000, it is the largest city in the Wine Country region and serves as a regional center for healthcare, retail, and government employment. Renters make up roughly half of Santa Rosa households — a share shaped by a tight housing market that was further squeezed after the 2017 Tubbs Fire destroyed thousands of homes and dramatically accelerated rent increases across the city.
Unlike San Francisco, Oakland, or Los Angeles, Santa Rosa has never enacted a local rent control ordinance. California's statewide Tenant Protection Act of 2019 — commonly called AB 1482 — is therefore the primary rent-increase and eviction protection available to most Santa Rosa renters. AB 1482 caps annual rent increases and requires landlords to cite a legally valid reason before terminating a tenancy, but it does not cover every unit and it is self-enforced, meaning no local rent board oversees compliance.
This guide explains which Santa Rosa rentals fall under AB 1482, how the rent cap is calculated using Bay Area CPI data, what just-cause eviction protections apply, and where to find free legal help if your landlord is not following the law.
2. Who Is Covered by Rent Control in Santa Rosa?
AB 1482 applies to a Santa Rosa rental unit if the building received its certificate of occupancy 15 or more years before the date of the rent increase or eviction notice. Because this is a rolling threshold, units built before approximately 2011 are generally covered as of 2026. The tenant must also have lived in the unit for at least 12 months before the protections fully apply.
Many Santa Rosa rentals are exempt from AB 1482. Units that are exempt include:
Single-family homes and condominiums — excluded under the Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535), provided the landlord has given proper written notice of the exemption
Buildings constructed within the last 15 years — any unit with a certificate of occupancy issued in 2011 or later is exempt as of 2026 (this cutoff moves forward each year)
Owner-occupied duplexes — where the owner lives in the other unit at the start of the tenancy
Single-family homes owned by corporations or real estate investment trusts (REITs) — these do NOT qualify for the SFH exemption and remain covered by AB 1482
Deed-restricted affordable housing — units subject to a government affordability covenant with their own rent restrictions
Transient and hotel occupancy — stays of fewer than 30 consecutive days
Dormitories — student housing owned by educational institutions

3. Maximum Allowable Rent Increases
For covered units in Santa Rosa, AB 1482 limits annual rent increases to 5% plus the local Consumer Price Index (CPI) percentage, with a hard ceiling of 10%. Santa Rosa falls within the San Francisco–Oakland–Hayward Metropolitan Statistical Area for CPI purposes, so the Bay Area CPI is the relevant figure.
For rent increases taking effect in 2025, the Bay Area CPI change was approximately 3.8%, making the allowable cap roughly 8.8% (5% + 3.8%). Landlords may choose whichever is lower between the formula result and 10%. The official CPI figures are published by the California Department of Housing & Community Development (HCD) and updated annually.
Key rules governing rent increases under AB 1482:
12-month waiting period: A landlord cannot raise rent under AB 1482 until a tenant has lived in the unit for at least 12 months.
No more than two increases per 12 months: Landlords may raise rent up to twice in any 12-month period, but the combined total cannot exceed the allowable cap.
No banking of unused increases: If a landlord skips a year's increase, those unused percentage points cannot be carried forward and added to a future year's cap.
Written notice required: Increases of 10% or less require 30 days' written notice; any increase over 10% (which AB 1482 prohibits for covered units) would require 90 days' notice.
If your landlord raises the rent above the AB 1482 cap without a valid exemption, the excess increase is void. You can withhold the excess portion without risking eviction for nonpayment — but document everything and seek legal advice before doing so.
4. Just Cause Eviction Protections
Once a tenant has lived in a Santa Rosa unit covered by AB 1482 for 12 months (or 24 months if there are multiple adults on the lease and at least one has been there 12 months), the landlord must cite a legally recognized just-cause reason to terminate the tenancy. Handing a tenant a no-cause 30- or 60-day notice is not lawful for covered units.
At-Fault Just Cause Reasons
These are grounds based on the tenant's conduct. No relocation assistance is owed.
Nonpayment of rent
Material breach of a lease term after written notice to cure
Maintaining a nuisance or causing substantial damage to the property
Criminal activity on or near the premises that affects the safety of other residents
Refusing the landlord lawful entry after proper notice
Using the unit for an unlawful purpose (e.g., illegal subletting)
Failure to vacate after a valid lease has expired and the landlord has declined to renew for a lawful reason
No-Fault Just Cause Reasons
These are grounds unrelated to tenant conduct. The landlord must pay the tenant one month's rent as relocation assistance (or waive the final month's rent).
Owner or qualified family member move-in: The landlord or a close family member intends to occupy the unit as a primary residence
Withdrawal under the Ellis Act: The landlord is permanently removing all units in the building from the rental market
Substantial remodel: Permitted work requiring the unit to be vacant for at least 30 days (permits must be obtained before issuing notice)
Demolition: The unit is being demolished pursuant to a local permit
The relocation assistance payment must be made within 15 calendar days of serving the eviction notice. If the landlord fails to pay, the eviction notice is defective and unenforceable. Always request proof of the permit or the family member's intent in writing.
5. Local Rules and Special Protections
Santa Rosa does not have a local rent stabilization or rent control ordinance. The City Council has not enacted one, and under the Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535), any local ordinance would be barred from covering single-family homes, condominiums, or units built after February 1, 1995 — which limits the practical scope of any future local law significantly.
In practical terms, this means there is no Santa Rosa Rent Board, no local registration requirement for landlords, no rent registry that tracks increases, and no local hearing process for rent disputes. Tenants must self-enforce their AB 1482 rights, which typically means sending a written demand letter, filing a complaint with the California Department of Consumer Affairs, or pursuing a civil claim in Sonoma County Superior Court.
Santa Rosa does operate a Housing Division through its Community Development Department that administers affordable housing programs, fair housing referrals, and rental assistance initiatives. The City's housing page at srcity.org/housing lists current programs. Separately, the Sonoma County Housing Authority administers Section 8 vouchers and other rental subsidy programs countywide at sonoma-county.org/housing.
The Community Action Partnership of Sonoma County (CAP Sonoma) at capsonoma.org provides emergency rental assistance and can connect tenants with housing counselors. These programs do not adjudicate landlord-tenant disputes but can offer critical financial stabilization while a tenant pursues their legal rights.

Check Your Address
Find out if your home is covered by rent control or tenant protections.
No. Santa Rosa has never enacted a local rent control or rent stabilization ordinance. The Costa-Hawkins Rental Housing Act limits what any California city can regulate locally, and the Santa Rosa City Council has not pursued even the partial protections that law permits. California's statewide AB 1482 (Tenant Protection Act of 2019) is the only rent-increase protection available to eligible Santa Rosa renters.
How much can my landlord raise my rent in Santa Rosa?
If your unit is covered by AB 1482, your landlord may raise the rent by no more than 5% plus the Bay Area CPI, up to a maximum of 10% per year. For 2025, that cap works out to approximately 8.8% (5% + 3.8% Bay Area CPI). The first increase cannot occur until you have lived in the unit for at least 12 months, and unused annual allowances cannot be banked for future years.
Does AB 1482 apply to my rental in Santa Rosa?
AB 1482 covers most Santa Rosa rentals in buildings that received a certificate of occupancy 15 or more years ago — generally pre-2011 construction as of 2026. Single-family homes and condos where the landlord has provided the required exemption notice are excluded under Costa-Hawkins, as are units in buildings constructed within the last 15 years and owner-occupied duplexes. Use RentCheckMe's address lookup at rentcheckme.com or call Legal Aid of Sonoma County to confirm your unit's status.
Can my landlord evict me without cause in Santa Rosa?
Not if your unit is covered by AB 1482 and you have lived there for at least 12 months. After that threshold, your landlord must cite a legally recognized at-fault reason (such as nonpayment of rent or a lease violation) or a no-fault reason (such as owner move-in or Ellis Act withdrawal). No-fault evictions require the landlord to pay you one month's rent as relocation assistance within 15 days of serving the notice. If no valid cause is stated, the eviction notice is likely unenforceable.
Where can I get help with a rent dispute in Santa Rosa?
Legal Aid of Sonoma County (legalaidsc.org) provides free legal help to income-eligible tenants and is the first call for most Santa Rosa renters facing an illegal rent increase or eviction. Bay Area Legal Aid (baylegal.org) and Tenants Together (tenantstogether.org) also serve the North Bay.
