🐻 California Rent Increase Laws
Complete Guide to AB 1482, Rent Caps & Local Ordinances
✅ Updated for • California Civil Code § 1947.12Last reviewed: January
The Tenant Protection Act of 2019 (AB 1482) caps annual rent increases at 5% + local CPI, maximum 10%. Many cities impose even stricter local limits (1–5%). Landlords must comply with both state and local law — always following whichever is more restrictive. This guide covers all requirements.
📑 What’s In This Guide
⚖️ California’s Tenant Protection Act (AB 1482)
The California Tenant Protection Act (AB 1482), signed October 8, 2019 and effective January 1, 2020, established the first statewide rent cap in California’s history. The law is set to expire January 1, 2030 (subject to legislative extension) and covers an estimated 8 million rental units statewide.
AB 1482 operates alongside the Costa-Hawkins Rental Housing Act (1995). Costa-Hawkins limits what local governments can do — it prevents cities from applying rent control to single-family homes, condos, and newer buildings, and guarantees vacancy decontrol. AB 1482 creates a baseline statewide protection that applies regardless of whether a city has local rent control.
📜 Key Provisions of AB 1482
- Rent Cap: Annual increases limited to 5% + local CPI, maximum 10%
- Just Cause Eviction: Required after 12 months of occupancy
- Disclosure: Landlords must notify tenants in writing whether property is subject to AB 1482
- Relocation Assistance: One month’s rent required for no-fault evictions
- Building Age: Applies to residential properties 15+ years old (rolling exemption)
- Frequency Limit: No more than two rent increases per 12-month period
- No Banking: Unused rent increases cannot be banked and applied in future years
- Sunset Date: Law expires January 1, 2030 unless extended
Costa-Hawkins (1995): Limits what LOCAL governments can do — prevents cities from applying rent control to single-family homes, condos, and newer buildings; guarantees vacancy decontrol.
AB 1482 (2019): Creates STATEWIDE protections — applies its own rent cap and just cause rules. Has its own separate exemptions.
When both state and local law apply, always follow the more restrictive rule.
📊 Rent Increase Limits & Caps
California’s rent cap formula: 5% + regional CPI, maximum 10% per year. The California Department of Finance publishes regional CPI data each April, which applies to rent increases effective August 1 through July 31 of the following year.
| Scenario | Base Rate | Regional CPI | Calculated Cap | Actual Cap Applied |
|---|---|---|---|---|
| Low Inflation Year | 5% | 2.0% | 7.0% | 7.0% |
| Moderate Inflation | 5% | 3.5% | 8.5% | 8.5% |
| Higher Inflation | 5% | 4.8% | 9.8% | 9.8% |
| High Inflation Year | 5% | 7.0% | 12.0% | 10.0% (capped) |
| Very High Inflation | 5% | 9.0% | 14.0% | 10.0% (capped) |
📅 California Allowable Rent Increases by Year
| Effective Period | LA Area | SF Bay Area | San Diego | Sacramento | Inland Empire |
|---|---|---|---|---|---|
| Aug 2025 – Jul 2026 | 8.0% | 7.8% | 8.2% | 8.0% | 8.5% |
| Aug 2024 – Jul 2025 | 8.9% | 8.6% | 8.8% | 8.6% | 9.0% |
| Aug 2023 – Jul 2024 | 10.0% | 10.0% | 10.0% | 10.0% | 10.0% |
| Aug 2022 – Jul 2023 | 10.0% | 10.0% | 10.0% | 10.0% | 10.0% |
| Aug 2021 – Jul 2022 | 9.1% | 8.9% | 9.0% | 8.8% | 9.2% |
Unused rent increases cannot be banked from one year to the next under AB 1482. However, some local ordinances (San Francisco, Oakland) DO allow banking — check your local rules. Always verify current CPI at dof.ca.gov before implementing any increase.

📬 Notice Requirements
California Civil Code § 827 requires written notice before any rent increase. The required notice period depends on the total increase over the previous 12 months, not just the current increase.
✅ Personal delivery to tenant (notice period begins immediately)
✅ Substituted service to resident adult + mailing
✅ Certified mail, return receipt requested (add 5 calendar days)
✅ Posting + mailing if personal service fails (add 5 calendar days)
Text messages, emails (unless tenant agreed in writing), verbal conversations, voicemail, notice mentioned only in lease renewal offer, bulletin board posting without mailing, or notice slipped under door without mailing follow-up.
🏠 Exemptions from AB 1482
Not all California rental properties are subject to AB 1482 rent caps. Each exemption has specific requirements — failure to comply with disclosure requirements can cost you an exemption you would otherwise qualify for.
🏗️ New Construction: Buildings < 15 years old
🏡 Qualifying SFH: Not owned by corp/REIT/LLC with corporate member + proper notice given
👤 Owner-Occupied Duplexes: Owner lives in one unit
📜 Stricter Local Rent Control: Units covered by more protective local ordinances
🏢 Affordable Housing: Units with deed-restricted affordability
🎓 Student/Care Facilities: Institution-operated housing
🏢 Apartment Buildings: Any multi-family 15+ years old
🏠 Corporate-Owned SFH: SFH owned by corporations or REITs
🏠 LLC-Owned SFH: LLCs where any member is a corporation
🏘️ Non-Owner Condos: Condos rented by non-resident owners (15+ years)
📝 No-Disclosure Properties: Otherwise-exempt properties where landlord failed to provide required written notice
Many landlords assume their SFH is automatically exempt — it is NOT. ALL conditions must be met: (1) Owner is NOT a REIT, corporation, or LLC with a corporate member, (2) Owner provides required written exemption notice using specific statutory language from Civil Code § 1947.12, (3) For existing tenants as of Jan 1, 2020, notice was provided by July 1, 2020. Failure to provide notice means the property is treated as covered by AB 1482.
The new construction exemption is a rolling 15-year window from certificate of occupancy date — recalculate annually. A building completed in 2015 becomes subject to AB 1482 in 2030. Mark your calendar for the year your building turns 15.
🏙️ Local Rent Control Ordinances
Many California cities have local rent control ordinances that predate AB 1482 and impose stricter limits. When local law provides greater tenant protection, it supersedes state law. Always follow whichever is more restrictive.
1. Is your property in a city with local rent control? → Check city housing department website.
2. Does your property meet local coverage criteria (building age, unit count)? → If yes, follow local (stricter) limits.
3. Not covered locally, but building is 15+ years old? → AB 1482 applies.
4. Exempt from both? → Raise to market rate with standard 30/90-day notice.
When in doubt: contact your local housing department or a California real estate attorney.
🛡️ Just Cause Eviction Requirements
AB 1482 requires landlords to have a valid “just cause” reason before evicting tenants who have occupied the property for 12 months or more (or if any tenant has occupied for 24+ months). Just cause reasons are divided into at-fault and no-fault categories.
💰 Nonpayment of rent after notice
📋 Material lease violation after notice to cure
🚨 Criminal activity or nuisance on premises
📝 Refusal to sign new lease with materially similar terms
🏚️ Unauthorized subletting
❌ Refusing lawful landlord access after proper notice
👤 Owner or immediate family moving in
🏗️ Substantial renovation requiring vacancy
🔒 Ellis Act withdrawal from rental market
📜 Government order requiring vacancy
🏢 Demolition of unit
💵 Must pay one month’s rent OR waive final month’s rent
For no-fault evictions under AB 1482, pay one month’s rent within 15 calendar days of serving the eviction notice, OR waive the tenant’s obligation to pay the final month’s rent. Local ordinances may require much higher amounts — San Francisco can require $7,000+ per tenant.
✅ Step-by-Step Compliance Guide
Verify Your Property’s Legal Status
Determine whether your property is subject to AB 1482, local rent control, both, or neither. Check certificate of occupancy date (15-year rule), ownership structure (SFH exemptions), and local rent control coverage. Document your findings.
Calculate Your Maximum Allowable Increase
For AB 1482 properties: 5% + regional CPI (maximum 10%). For local rent control: check your rent board’s published annual adjustment. Verify current CPI at dof.ca.gov. Consider whether you’ve already raised rent in the past 12 months — combined increases cannot exceed the annual cap.
Determine Required Notice Period
Calculate total rent increase over past 12 months. 10% or less total = 30 days notice. Over 10% total = 90 days notice. Add 5 days if serving by mail. Verify local ordinance requirements — some cities have different or additional notice rules.
Prepare and Serve Written Notice
Draft a notice including: current rent, new rent, dollar and percentage increase, effective date, and your signature. Include reference to applicable law. Personally deliver or serve by approved method. Add 5 days for mailed notices. Keep proof of service.
Document Everything & Update Records
Maintain a complete file: copy of notice, proof of service, CPI data and calculations, tenant communications. Keep records for at least 4 years. Update rent roll and accounting systems on the effective date.
📖 Real-World Scenarios
📊 Scenario 1: Standard AB 1482 Rent Increase
Situation: Maria owns a 25-year-old apartment in Sacramento (no local rent control). Current rent is $1,800/month. Regional CPI is 3%.
Calculation: 5% + 3% = 8% maximum. $1,800 × 8% = $144. New rent: $1,944/month.
Notice Required: 30 days (8% is under 10%).
⛔ Scenario 2: Exceeding the Rent Cap
Situation: John owns a covered duplex in LA. Tenant pays $2,000/month and hasn’t had an increase in 3 years. John wants to raise rent 30% to catch up with market rates.
Problem: Maximum allowable is 8% ($160). John cannot “bank” unused increases from prior years.
🏠 Scenario 3: Single-Family Home Without Disclosure
Situation: Susan owns a SFH in her personal name. She rented it in 2022 but never provided the AB 1482 exemption notice to her tenant.
Issue: Although Susan’s property would otherwise be exempt, failure to provide the required written notice means the property is treated as covered by AB 1482.
🏙️ Scenario 4: Local Rent Control vs. AB 1482
Situation: David owns a 1975 apartment in San Francisco. SF Rent Board allows 1.4% this year. AB 1482 would allow 8%.
Rule: When local rent control is more restrictive, local law controls.
🔄 Scenario 5: Vacancy Decontrol
Situation: Linda’s tenant in a rent-controlled Oakland apartment voluntarily moves out. The tenant paid $1,500/month. Market rent is $2,400.
Rule: Under Costa-Hawkins, landlords can reset rent to market rate when a unit becomes vacant.
⚠️ Penalties for Violations
💰 Rent Refund with Interest: Tenants can recover all excess rent paid above the legal limit
⚖️ Actual Damages: Courts may award additional damages for harm caused
📋 Attorney Fees: Prevailing tenants typically recover attorney fees from the landlord
⚡ Punitive Damages: In willful violation cases, courts may award punitive damages
🛡️ Defense to Eviction: Improper rent increase is an absolute defense to nonpayment eviction
🏛️ Local Administrative Penalties: Many cities impose fines of $1,000–$10,000+ per violation
🔍 Start With Quality Tenants
