1. Overview of Rent Control in Westminster

Westminster sits in the heart of northwestern Orange County, bordered by Garden Grove, Huntington Beach, and Seal Beach. The city is home to roughly 91,000 residents and is nationally recognized as the hub of Little Saigon, the largest Vietnamese-American commercial district in the United States. A significant share of Westminster households rent rather than own, and many of those renters occupy older apartment complexes built during the city's mid-20th-century suburban expansion — units that are now squarely within the coverage window of California's statewide AB 1482 protections.

Westminster has never enacted a local rent control ordinance, and state law — specifically the Costa-Hawkins Rental Housing Act — sharply limits what any California city can do on that front. The result is that renters here rely entirely on AB 1482, the Tenant Protection Act of 2019, for rent increase limits and just-cause eviction protections. AB 1482 caps annual rent increases at 5% plus the local Consumer Price Index (maximum 10%) and requires landlords to demonstrate a legally recognized reason before evicting a tenant who has lived in the unit for at least 12 months.

This article explains exactly which Westminster rentals AB 1482 covers, how the rent cap is calculated using the Los Angeles metro CPI, what qualifies as just cause for eviction, and where Westminster renters can turn for free legal help.

2. Who Is Covered by Rent Control in Westminster?

AB 1482 covers a residential rental unit in Westminster if its certificate of occupancy was issued at least 15 years ago. Because the rule is rolling, units that were covered in prior years can lose coverage as new buildings age in — but as of 2026, the practical cutoff is units built before approximately 2011. The unit must also be used as a primary residence, and the tenant must have lived there for at least 12 months before the rent cap or just-cause eviction protections kick in.

Many Westminster apartments — especially the dense garden-style complexes along Bolsa Avenue, Westminster Boulevard, and Magnolia Street — fall squarely within AB 1482 coverage. However, several common rental types are exempt:

• Single-family homes and condominiums — excluded statewide by the Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535), regardless of how old they are, unless the owner has provided the legally required AB 1482 exemption notice
• Units built within the last 15 years — any unit with a certificate of occupancy issued after approximately 2011 is exempt until it ages into the 15-year window
• Owner-occupied duplexes — if the landlord lives in the other unit of a two-unit building, both units are exempt
• Corporate-owned single-family homes with proper exemption notice — REITs and corporations owning SFHs may still be exempt if they have correctly notified tenants
• Government-subsidized affordable housing — units with their own stricter rent restrictions (such as Section 8 project-based housing) operate under those rules instead
• Transient and hotel accommodations — short-term rentals and hotels are not covered
• Dormitories — housing owned and operated by educational institutions is excluded

If you are unsure whether your Westminster unit qualifies, use the RentCheckMe address lookup at rentcheckme.com or contact a local legal aid organization.

3. Maximum Allowable Rent Increases

For covered Westminster rentals, AB 1482 limits annual rent increases to 5% plus the percentage change in the regional Consumer Price Index, with a hard ceiling of 10%. Westminster falls within the Los Angeles–Long Beach–Anaheim metropolitan area CPI region, published by the U.S. Bureau of Labor Statistics. For 2025, that regional CPI figure is approximately 3.8%, making the effective maximum increase for most covered Westminster units roughly 8.8% (5% + 3.8%). Landlords should always verify the current CPI figure directly with the California Department of Housing and Community Development before issuing a notice of rent increase.

Key rules governing how and when increases can be applied:

• 12-month waiting period: A landlord cannot impose any AB 1482 rent increase until the tenant has occupied the unit for at least 12 months. After that threshold, a landlord may raise rent no more than twice in any 12-month period, as long as the combined total does not exceed the annual cap.
• No banking of unused increases: If a landlord skips a year or raises rent by less than the cap, the unused portion cannot be carried forward and added to a future year's increase.
• Proper notice required: Rent 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 under California law.
• No local rent board: Because Westminster has no rent board, there is no agency tracking or approving increases. Tenants must self-monitor and, if an increase exceeds the cap, seek help through legal aid or Housing Is Key.

4. Just Cause Eviction Protections

Once a Westminster tenant covered by AB 1482 has lived in their unit for 12 or more months, the landlord must have a legally recognized just cause reason to terminate the tenancy. Absent that reason, a landlord cannot issue a valid eviction notice — even at the end of a lease term.

At-fault just cause reasons (tenant has done something wrong):

• Nonpayment of rent
• Material breach of the lease after written notice and failure to cure
• Nuisance, waste, or unlawful use of the unit
• Criminal activity on or near the premises
• Refusal to sign a substantially similar lease renewal
• Subletting in violation of the lease
• Refusing lawful entry by the landlord after proper notice
• Using the unit for an unauthorized purpose

No-fault just cause reasons (tenant has done nothing wrong):

• Owner or qualified family member move-in — landlord or a close family member intends to occupy the unit as a primary residence
• Withdrawal from the rental market (Ellis Act) — landlord is permanently removing all units in the building from the rental market
• Substantial remodel — work requiring permits and at least 30 days of displacement that cannot reasonably be done with the tenant in place
• Demolition — landlord has obtained a demolition permit

Relocation assistance for no-fault evictions: When a landlord uses a no-fault just cause reason, AB 1482 requires the landlord to pay the tenant one month's rent as relocation assistance, or alternatively to waive the final month's rent. This payment must be made at the time the notice is served, not at move-out. Failure to pay relocation assistance renders the notice of termination void.

5. Local Rules and Special Protections

Westminster has no local rent control ordinance and no city rent board. The city has not enacted any municipal tenant protection laws that supplement or modify AB 1482. This means Westminster renters have no local administrative agency to file complaints with, no local mediation program for rent disputes, and no additional caps or protections beyond what state law provides.

Why no local ordinance? The Costa-Hawkins Rental Housing Act (California Civil Code §§ 1954.50–1954.535) prohibits California cities from imposing rent control on single-family homes, condominiums, and any units built after February 1, 1995. Given that a large portion of Westminster's rental inventory consists of single-family homes or post-1995 construction, a local ordinance would cover a relatively narrow slice of the market — and the political will to pass one has not materialized on the Westminster City Council.

In practical terms, this means:

• There is no local agency to call if your landlord raises your rent above the AB 1482 cap — you must either negotiate directly with your landlord or seek help from a legal aid organization.
• Westminster's city housing department (westminster-ca.gov/housing) primarily administers federal housing assistance programs (such as Section 8 vouchers through the Orange County Housing Authority) rather than enforcing tenant protections.
• If your unit is exempt from AB 1482 — for example, a single-family home or a newer apartment — your landlord faces no statutory cap on rent increases, though they must still provide proper advance notice under California Civil Code § 827.

The Orange County Housing Authority (ochousing.org) and Community Action Partnership of Orange County (capoc.org) offer housing counseling, emergency rental assistance referrals, and other programs that may benefit Westminster renters in financial distress.
