California Rent Increase Notice

California Rent Increase Law – Complete Guide

AB 1482 – California Tenant Protection Act

California’s statewide rent control law (Assembly Bill 1482, effective January 2020) limits rent increases statewide. However, many cities have STRICTER local rent control.

Properties Covered by AB 1482:

• Buildings 15+ years old (from certificate of occupancy date)
• After tenant has resided for 12+ months
• All residential properties UNLESS exempted

Properties EXEMPT from AB 1482:

• Single-family homes (IF landlord provides written exemption notice to tenant)
• Condominiums (IF owner provides written exemption notice to tenant)
• Housing built within last 15 years
• Properties already subject to local rent control ordinances (local rules apply instead)

Maximum Rent Increase Under AB 1482

Annual Rent Cap: 10% Maximum (or less)

The allowed increase is the LOWER of:

• 5% + local Consumer Price Index (CPI), OR
• 10%

2024-2025 CPI Rates:

• Most California regions: ~4-5% CPI
• Therefore: 5% + 4% = 9% (this is less than 10%, so 9% is the max)
• Practical maximum: Usually around 9-10% depending on your area’s CPI

Safe Assumption: Never exceed 10% increase in any 12-month period. Most regions will have 9-10% as the actual maximum.

Notice Period Requirements

California requires different notice periods based on the AMOUNT of increase:

30-Day Notice (Increase Under 10%):

• If rent increase is less than 10% of current rent
• Must provide at least 30 days advance written notice
• Notice delivered on March 1 → Effective April 1 (or later)

90-Day Notice (Increase 10% or More):

• If rent increase is 10% or more of current rent
• Must provide at least 90 days advance written notice
• Notice delivered on March 1 → Effective June 1 (or later)

12-Month Rule

You can only raise rent once every 12 months under AB 1482:

• Count from the date the LAST increase went into effect (not when notice was given)
• Must wait full 12 months before next increase
• Example: Last increase effective July 1, 2024 → Cannot raise again until July 1, 2025

When Rent Increase Takes Effect

The increase takes effect on the tenant’s regular rent due date AFTER the notice period expires:

For Month-to-Month Tenancies:

• 30-day notice: Effective on rent due date 30+ days after notice
• 90-day notice: Effective on rent due date 90+ days after notice

Example (30-day notice, rent due 1st of month):

• Notice mailed/delivered: March 5
• 30 days later: April 5
• Next rent due date: May 1
• Increase effective: May 1

Example (90-day notice, rent due 15th of month):

• Notice mailed/delivered: January 10
• 90 days later: April 10
• Next rent due date after April 10: April 15
• Increase effective: April 15

How to Properly Deliver Notice

California requires WRITTEN notice. Acceptable methods:

Personal Delivery:

• Hand notice directly to tenant
• Most reliable method
• Get tenant signature acknowledging receipt (optional but recommended)

Mail (First-Class):

• Send via USPS first-class mail
• Certified mail with return receipt recommended (proof of delivery)
• Notice period starts when mailed (but add 5 days for mailing time)

Substitute Service:

• Leave with another adult at residence
• PLUS mail a copy

Fixed-Term Leases vs. Month-to-Month

Fixed-Term Leases:

• CANNOT raise rent during the lease term (unless lease specifically allows it)
• Can only raise rent when lease renews or converts to month-to-month
• Notice period applies to renewal increases

Month-to-Month Tenancies:

• Can raise rent with proper notice (30 or 90 days)
• Must comply with AB 1482 10% cap and 12-month rule
• Tenant can reject increase by giving 30-day move-out notice

Common Mistakes to Avoid

• ❌ Raising rent more than 10% in 12 months (AB 1482 violation)
• ❌ Raising rent twice within 12 months (AB 1482 violation)
• ❌ Giving only 30 days notice for 10%+ increase (requires 90 days)
• ❌ Not checking local rent control ordinances first
• ❌ Calculating notice period from when notice is received instead of delivered
• ❌ Raising rent during fixed-term lease without authorization
• ❌ Verbal or email notice instead of written notice
• ❌ Forgetting to align effective date with rent due date

Sample Rent Increase Calculations

Example 1: Safe Increase

• Current rent: $2,000/month
• Proposed new rent: $2,180/month
• Dollar increase: $180
• Percentage: 9% (under 10% cap ✅)
• Notice required: 30 days ✅
• Result: LEGAL under AB 1482

Example 2: Violation (Too High)

• Current rent: $1,500/month
• Proposed new rent: $1,800/month
• Dollar increase: $300
• Percentage: 20% (exceeds 10% cap ❌)
• Result: ILLEGAL under AB 1482
• Maximum allowed: $1,650 (10% = $150 increase)

Example 3: Need 90-Day Notice

• Current rent: $3,000/month
• Proposed new rent: $3,300/month
• Percentage: 10% (exactly at cap)
• Notice required: 90 days (not 30) ⚠️
• Result: Legal IF 90-day notice given

What If Tenant Refuses to Pay New Rent?

If you properly noticed a legal rent increase:

• Tenant must pay new amount starting on effective date
• If tenant pays only old amount, they are now in arrears
• You can serve 3-Day Pay or Quit notice for the difference
• If tenant still refuses, you can file eviction for nonpayment

Tenant Options:

• Pay the new rent (accept the increase)
• Give 30-day notice to vacate (reject by leaving)
• Challenge the increase (if illegal) by refusing to pay and defending eviction
