Key Takeaways
Most multi-unit rentals with certificates of occupancy issued before 2011 (rolling 15-year rule); single-family homes and condos are exempt
5% + LA Metro CPI (max 10%/year); approximately 8.8% cap for 2025
AB 1482 requires just cause for eviction after 12 months of tenancy
Rancho Cucamonga sits in the western Inland Empire, straddling the San Bernardino County foothills roughly 37 miles east of downtown Los Angeles. The city has grown into one of the Inland Empire's most populous communities — home to around 180,000 residents — and its relatively affordable rents compared to coastal LA County have drawn a steady stream of renters priced out of Los Angeles and Orange County. That demand has pushed rents upward and made tenant protections increasingly relevant.
Unlike cities such as Los Angeles, Long Beach, or San Francisco, Rancho Cucamonga has never enacted a local rent stabilization or just-cause eviction ordinance. California's statewide Tenant Protection Act of 2019 — commonly called AB 1482 — fills part of that gap by capping annual rent increases and requiring landlords to show just cause before evicting long-term tenants. However, AB 1482 leaves out a significant portion of the rental stock, including single-family homes, condominiums, and newly built apartments.
This guide explains which Rancho Cucamonga rentals AB 1482 covers, how the rent cap is calculated using the Los Angeles metro Consumer Price Index, what eviction protections apply, and where to find local legal help if your landlord oversteps.
2. Who Is Covered by Rent Control in Rancho Cucamonga?
AB 1482 applies to residential rental units in Rancho Cucamonga that meet the following criteria: the building must have received its certificate of occupancy at least 15 years ago (a rolling date — as of 2026, that means units built before 2011 are generally covered), and the tenant must have lived in the unit for at least 12 months. Most traditional apartment complexes in older Rancho Cucamonga neighborhoods qualify.
The following types of rentals are exempt from AB 1482 and receive no rent cap or just-cause eviction protections under state law:
Single-family homes and condominiums — protected from local rent control by the Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535), and also exempt from AB 1482 unless the owner has given proper written notice that the law does not apply
Buildings constructed within the last 15 years — units that received a certificate of occupancy in 2011 or later (as of 2026) are exempt; this cutoff advances each year
Owner-occupied duplexes — where the landlord lives in one of the two units
Corporate-owned single-family homes where the owner is a real estate investment trust (REIT), a corporation, or an LLC in which at least one member is a corporation
Transient and hotel occupancies — short-term rentals, motels, and similar accommodations
Government-subsidized affordable housing — units subject to deed restrictions or regulatory agreements that impose their own rent limits (e.g., Section 8 project-based housing)
Dormitories operated by schools, colleges, or universities
If you are unsure whether your unit is covered, check your lease for any AB 1482 exemption notice — landlords of exempt single-family homes and condos are required to provide written disclosure — and use the RentCheckMe address lookup to verify coverage.
3. Maximum Allowable Rent Increases
For covered units in Rancho Cucamonga, AB 1482 caps annual rent increases at 5% plus the local Consumer Price Index (CPI), with a hard maximum of 10% per year. Rancho Cucamonga falls within the Los Angeles–Long Beach–Anaheim metropolitan area CPI region, published by the U.S. Bureau of Labor Statistics. For 2025, the applicable CPI figure is approximately 3.8%, making the effective cap roughly 8.8% for most covered tenants in the city. This figure shifts each year as CPI is recalculated.
Key rules tenants should know:
12-month waiting period: A landlord cannot impose any AB 1482-covered increase until a tenant has lived in the unit for at least 12 months, and cannot raise rent more than twice in any 12-month period.
No banking of unused increases: If a landlord skips an increase in a given year, they cannot carry that unused percentage forward and combine it with a future year's cap.
Proper notice required: A rent increase of 10% or less requires at least 30 days' written notice; an increase of more than 10% (which would violate AB 1482 for covered units) would require 90 days' notice under Civil Code § 827.
Base rent calculation: The cap applies to the rent in effect on March 15, 2019, or the lowest rent charged in the 12 months before the increase, whichever is lower, for increases going back to the law's effective date.
If your landlord raises the rent above the allowable cap without a valid exemption, the increase is void and unenforceable. You are not obligated to pay the excess amount, and you may have grounds to recover it if you already paid it.
4. Just Cause Eviction Protections
Once you have lived in a covered Rancho Cucamonga rental for 12 months (or if any tenant in the household has lived there for 24 months), your landlord must have a legally recognized just cause to terminate your tenancy or refuse to renew your lease.
At-fault just cause reasons — where the tenant has done something wrong:
Nonpayment of rent
Material breach of the lease after written notice and a reasonable opportunity to cure
Maintaining a nuisance or causing substantial damage to the property
Illegal use of the rental unit
Refusal to allow the landlord lawful entry after proper notice
Using the unit for an unauthorized sublease or assignment after written notice
Criminal activity on the premises that threatens the safety of others
Failure to vacate after a lawful lease expiration where the tenant was properly notified the tenancy would not be renewed
No-fault just cause reasons — where the tenant has done nothing wrong:
Owner move-in: The landlord (or a qualified family member) intends to occupy the unit as their primary residence
Ellis Act withdrawal: The landlord is permanently removing all units in the building from the rental market
Substantial remodel: Work requiring permits that cannot safely be performed with a tenant in place, and that will take at least 30 days
Demolition: The landlord has obtained all necessary permits to demolish the building
Relocation assistance: For any no-fault eviction, the landlord must either waive the final month's rent or pay the tenant a relocation assistance payment equal to one month's rent. This payment is due at the time the notice to vacate is served, not at move-out. Failure to provide it renders the notice defective.
These protections do not apply during the first 12 months of tenancy, during which a landlord may terminate with proper notice and no stated reason — another reason why signing a longer lease or verifying your unit's coverage is important.
5. Local Rules and Special Protections
Rancho Cucamonga has no local rent stabilization ordinance, no rent board, and no city-level just-cause eviction law. The City Council has not enacted any renter protection measures beyond what California state law requires. This means there is no local agency to file a complaint with if your landlord raises the rent illegally — enforcement of AB 1482 is self-directed, meaning tenants must assert their own rights or seek outside legal help.
The absence of a local ordinance is partly structural: the Costa-Hawkins Rental Housing Act (Civil Code §§ 1954.50–1954.535) prohibits California cities from imposing rent control on units built after February 1, 1995, single-family homes, and condominiums. Given that a large share of Rancho Cucamonga's rental stock consists of newer construction and single-family homes — the city expanded rapidly through master-planned developments in the 1980s and 1990s — Costa-Hawkins significantly limits the practical reach any local ordinance could have even if the City Council chose to pass one.
For housing code violations, habitability complaints, and property maintenance issues, tenants can contact the City of Rancho Cucamonga's Community Improvement Division at cityofrc.us/housing, which enforces municipal codes related to property conditions. The city does not mediate rent disputes. Renters seeking help with illegal rent increases or unlawful evictions should contact Inland Counties Legal Services or the San Bernardino County Bar Association's lawyer referral service directly.

Find out if your home is covered by rent control or tenant protections.
No. Rancho Cucamonga has no local rent stabilization ordinance or rent board. California's statewide AB 1482 (Tenant Protection Act of 2019) is the only rent increase protection available to eligible renters in the city. Because much of Rancho Cucamonga's housing stock consists of newer construction and single-family homes — both exempt under Costa-Hawkins — a significant share of local renters fall outside any rent cap altogether.
How much can my landlord raise my rent in Rancho Cucamonga?
For units covered by AB 1482, your landlord may raise rent by no more than 5% plus the Los Angeles metro CPI, with a hard ceiling of 10% per year. For 2025, the effective cap is approximately 8.8%. The cap only applies after you have lived in the unit for 12 months, and the landlord cannot raise rent more than twice in any 12-month period or bank unused increases from prior years.
Does AB 1482 apply to my rental in Rancho Cucamonga?
AB 1482 covers most multi-unit apartment buildings in Rancho Cucamonga that received a certificate of occupancy before 2011 (the rolling 15-year cutoff as of 2026). It does not cover single-family homes, condominiums, owner-occupied duplexes, or buildings constructed within the past 15 years. Check your lease for any AB 1482 exemption notice — landlords of exempt single-family homes and condos are legally required to disclose this — or use the RentCheckMe address lookup at rentcheckme.com to verify.
Can my landlord evict me without cause in Rancho Cucamonga?
If your unit is covered by AB 1482 and you have lived there for at least 12 months, your landlord must provide a legally valid just-cause reason to evict you — either an at-fault reason (such as nonpayment of rent or lease violation) or a no-fault reason (such as owner move-in or Ellis Act withdrawal). For no-fault evictions, you are entitled to relocation assistance equal to one month's rent. During the first 12 months of tenancy, AB 1482 just-cause protections do not yet apply.
Where can I get help with a rent dispute in Rancho Cucamonga?
Because Rancho Cucamonga has no local rent board, tenants must seek outside help. Inland Counties Legal Services (inlandlegal.org) provides free legal aid to low-income San Bernardino County residents and is the primary resource for local renters facing illegal rent increases or eviction. The San Bernardino County Bar Association (sbcba.org) offers a lawyer referral service for paid consultations.
