Key Takeaways
Most multi-unit rentals built before 2011 (15-year rolling rule); single-family homes and condos are exempt under Costa-Hawkins
5% + Bay Area CPI, capped at 10% per year; 2025 cap is approximately 8.8% for most Bay Area units
After 12 months of tenancy, landlords must have a valid at-fault or no-fault just cause reason to evict
Sunnyvale sits at the geographic center of Silicon Valley in Santa Clara County, bordered by Mountain View, Cupertino, and Santa Clara. With a population of roughly 155,000 and one of the highest concentrations of tech-sector workers in the country, Sunnyvale's rental market is among the most expensive in California. Median rents for a two-bedroom apartment routinely exceed $3,000 per month, and the city's vacancy rate is persistently low, giving landlords significant pricing power in a competitive market.
Sunnyvale has never enacted a local rent stabilization or just-cause eviction ordinance. The city council has not moved to establish a rent board or tenant protection program beyond what state law mandates. As a result, the primary legal protection available to Sunnyvale renters is California's AB 1482 Tenant Protection Act of 2019, which imposes a statewide annual rent cap and requires just-cause justification for evictions in eligible units. Because AB 1482 is a state law rather than a local ordinance, there is no city rent board to file complaints with — tenants must self-enforce their rights or seek outside legal help.
This article explains which Sunnyvale rentals AB 1482 covers, how the rent cap is calculated using Bay Area CPI data, what qualifies as just cause for eviction under state law, and where Sunnyvale renters can turn for legal assistance.
2. Who Is Covered by Rent Control in Sunnyvale?
AB 1482 covers residential rental units in Sunnyvale that received their certificate of occupancy at least 15 years before the current date. Because the rule rolls forward each year, units that were newly constructed as recently as 2010 are now generally covered as of 2026. This includes most older apartment buildings, duplexes where the owner does not reside in the other unit, and multi-unit buildings throughout Sunnyvale's denser neighborhoods near downtown and El Camino Real.
To receive AB 1482 protections, a tenant must also have lived in the unit for at least 12 months. The protections do not kick in during the first year of tenancy.
The following types of Sunnyvale rentals are exempt from AB 1482:
Single-family homes and condominiums — excluded by the Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535), unless the owner is a real estate investment trust (REIT), a corporation, or an LLC where one member is a corporation
Units built within the last 15 years — any unit with a certificate of occupancy issued after approximately 2011 (as of 2026) is exempt; this covers a significant portion of Sunnyvale's newer apartment stock near the Lawrence Expressway and Mathilda Avenue corridors
Owner-occupied duplexes — where the landlord lives in one of the two units
Corporate-owned single-family homes — conversely, SFHs owned by a REIT, corporation, or LLC with a corporate member are not exempt and may be covered
Government-subsidized affordable housing — units already subject to stricter affordability restrictions through HUD programs, tax-credit agreements, or other government contracts
Transient and hotel occupancy — short-term rentals and hotels are not covered
Commercial properties — AB 1482 applies only to residential tenancies

3. Maximum Allowable Rent Increases
For covered Sunnyvale rentals, AB 1482 limits annual rent increases to 5% plus the local Consumer Price Index (CPI) percentage, with an absolute maximum of 10% per year. Sunnyvale falls within the San Francisco-Oakland-Hayward Metropolitan Area CPI region, published by the U.S. Bureau of Labor Statistics. Landlords must use the April-to-April CPI change for the prior year when calculating the allowable increase.
For rent increases taking effect in 2025, the Bay Area CPI increase was approximately 3.8%, making the allowable cap roughly 8.8% (5% + 3.8%) for most covered Sunnyvale units — well below the 10% ceiling. The exact figure can shift year to year depending on regional inflation, so tenants should verify the current CPI figure before accepting any increase notice.
Additional rules that govern rent increases under AB 1482:
12-month waiting period: A landlord cannot impose an AB 1482-regulated increase until a tenant has resided in the unit for at least 12 months.
No banking of unused increases: If a landlord skips an annual increase or raises rent by less than the cap, the unused percentage cannot be carried forward and stacked onto a future year's increase.
Maximum of two increases per year: Landlords may raise rent up to twice in any 12-month period, but the combined total of those increases cannot exceed the annual cap.
Written notice required: A rent increase of 10% or less requires 30 days' written notice; any increase above 10% (which would not be permissible under AB 1482 for covered units) requires 90 days' notice under Civil Code § 827.
Sunnyvale tenants who receive a rent increase notice should calculate the maximum allowable amount using the current Bay Area CPI figure and compare it against what their landlord is demanding. If the proposed increase exceeds the cap, the excess portion is unenforceable, and the tenant can challenge it.
4. Just Cause Eviction Protections
Once a Sunnyvale tenant has lived in a covered unit for 12 months (or if any member of the household has lived there for 24 months), the landlord must have a legally valid just-cause reason to terminate the tenancy under AB 1482. Without a qualifying reason, a termination notice is legally defective and unenforceable.
At-Fault Just Cause
At-fault evictions are based on the tenant's conduct. The landlord is not required to pay relocation assistance for at-fault evictions. Qualifying reasons include:
Nonpayment of rent
Material breach of the lease that remains uncured after written notice
Maintaining, committing, or permitting a nuisance on the property
Committing waste (significant damage) to the unit
Refusal to execute a new lease with materially similar terms after the prior lease expires
Criminal activity on the premises or against other residents or the landlord
Subletting the unit in violation of the lease
Refusal to allow the landlord lawful entry after proper notice
Using the unit for an unlawful purpose
No-Fault Just Cause
No-fault evictions occur for reasons unrelated to tenant behavior. For these, AB 1482 requires the landlord to pay the tenant one month's rent as relocation assistance (or waive the final month's rent). Qualifying no-fault reasons include:
Owner move-in: The landlord or a qualifying family member intends to occupy the unit as their primary residence
Ellis Act withdrawal: The landlord is removing all units in the building from the rental market entirely
Substantial remodel: Renovation work requiring a permit and more than 30 days to complete, requiring the unit to be vacated (landlords cannot use cosmetic upgrades to trigger this)
Demolition: The landlord has obtained all required permits to demolish the building
In Sunnyvale, where tech-industry landlords and institutional investors own a significant share of apartment stock, owner move-in and remodel evictions are the most commonly cited no-fault grounds. Tenants who receive a no-fault termination notice should verify that the stated reason is genuine and that the relocation payment has been properly tendered before vacating.
5. Local Rules and Special Protections
Sunnyvale has no local rent control ordinance, no rent stabilization program, and no municipal rent board. The city council has not adopted any local tenant protection measures beyond the baseline requirements of state law. This means Sunnyvale renters have fewer procedural protections than tenants in nearby cities like Mountain View or San Jose, both of which maintain local rent boards that accept complaints and mediate disputes.
The absence of a local ordinance is partly structural: California's Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535) prohibits cities from applying rent control to single-family homes, condominiums, or units built after February 1, 1995. Because a substantial share of Sunnyvale's rental housing stock is newer construction built during the tech boom of the 1990s and 2000s, Costa-Hawkins would limit the practical reach of any local ordinance even if the city were to enact one.
Without a local rent board, Sunnyvale tenants who believe AB 1482 has been violated have two main options: (1) send a written demand to the landlord citing the applicable Civil Code section, or (2) file a lawsuit in Santa Clara County Superior Court for unlawful rent increases or wrongful eviction. The California Department of Consumer Affairs and the California Attorney General's office do not have a dedicated intake process for individual AB 1482 complaints.
The City of Sunnyvale's Housing Division (sunnyvale.ca.gov/housing) administers affordable housing programs and can provide referrals to assistance programs, but it does not adjudicate landlord-tenant disputes. The Santa Clara County Housing Authority (hacsc.org) administers Section 8 vouchers and can assist income-eligible tenants, but similarly does not handle rent control enforcement.

Check Your Address
Find out if your home is covered by rent control or tenant protections.
No. Sunnyvale has never enacted a local rent stabilization ordinance or established a city rent board. Renters in Sunnyvale are protected only by California's statewide AB 1482 Tenant Protection Act of 2019, which caps rent increases and requires just-cause evictions for eligible units. Because there is no local board, tenants must enforce their AB 1482 rights on their own or through legal aid.
How much can my landlord raise my rent in Sunnyvale?
If your unit is covered by AB 1482, your landlord can raise rent by no more than 5% plus the Bay Area CPI percentage, capped at 10% per year. For 2025, the Bay Area CPI increase was approximately 3.8%, making the allowable cap roughly 8.8% for most covered Sunnyvale units. If your unit is exempt — for example, a newer building or a single-family home — AB 1482's cap does not apply and there is no legal limit on rent increases beyond the notice requirements in your lease.
Does AB 1482 apply to my rental in Sunnyvale?
AB 1482 applies if your unit received its certificate of occupancy at least 15 years ago (generally pre-2011 as of 2026) and you have lived there for at least 12 months. Single-family homes, condominiums, owner-occupied duplexes, and units in buildings constructed within the last 15 years are exempt. Use the free address lookup at RentCheckMe.com to check your specific unit, or contact Bay Area Legal Aid for a personalized assessment.
Can my landlord evict me without cause in Sunnyvale?
If your tenancy is covered by AB 1482 and you have lived in the unit for at least 12 months, your landlord must provide a legally valid just-cause reason to terminate your tenancy. At-fault causes include nonpayment of rent and lease violations; no-fault causes include owner move-in and Ellis Act withdrawal. For no-fault evictions, the landlord must pay you one month's rent as relocation assistance. Tenants in exempt units — such as newer construction or single-family homes — do not have AB 1482 just-cause protection.
Where can I get help with a rent dispute in Sunnyvale?
