How to Raise Rent in California: AB 1482 Rules & Step-by-Step Guide (2026)

Quick Summary: California's AB 1482 (the Tenant Protection Act) caps annual rent increases at 5% plus local CPI, with a maximum of 10%, for most residential properties built more than 15 years ago. To raise rent legally, you must calculate the correct amount, serve written notice at least 30 days in advance (90 days for increases over 10%), and ensure your property isn't subject to stricter local rent control. This guide walks through every step.

Raising rent is one of the most important—and legally sensitive—things a California landlord does. Get it wrong and you risk violating state law, triggering tenant complaints, or having to rescind the increase entirely. Get it right and you maintain cash flow that keeps pace with rising operating costs.

Since AB 1482 took effect in 2020, the rules have been clear but frequently misunderstood. Many landlords either leave money on the table by not raising rent when they legally can, or they inadvertently violate the law by raising it too much or without proper notice. This guide eliminates the guesswork.

Does AB 1482 Apply to Your Property?

Before calculating any rent increase, confirm whether AB 1482 governs your property. The law does not apply to all residential rentals in California—significant categories are exempt.

Properties Exempt from AB 1482

• Single-family homes and condos where the owner has provided proper written notice of the exemption to the tenant (using the specific language required by Civil Code § 1946.2(e)(8))
• Properties built within the last 15 years — rolling exemption based on Certificate of Occupancy date
• Owner-occupied duplexes where the landlord lives in one unit
• Properties owned by non-profit housing corporations
• Student housing owned by educational institutions
• Single-family homes subject to deed restrictions limiting affordability

The 15-year rolling exemption is commonly misunderstood. A property built in 2008 was not exempt in 2023 but became exempt in 2024 when it reached 15 years. A property built in 2010 becomes exempt in 2025. Track your property's build date carefully.

Single-Family Home and Condo Exemption: The Notice Requirement

Many Placer County landlords own single-family homes that are technically exempt from AB 1482—but only if they provided the required statutory notice. California Civil Code § 1946.2(e)(8) specifies exact language that must appear in the lease or be delivered to the tenant:

"This property is not subject to the rent limits imposed by Section 1947.12 of the Civil Code and is not subject to the just cause requirements of Section 1946.2 of the Civil Code. This does not mean that the owner may not seek to evict you for reasons not provided in Section 1946.2; however, any such eviction must comply with applicable state and local law."

If this notice was not included in your lease or delivered separately, your single-family home may be subject to AB 1482 protections even though it would otherwise qualify for the exemption. Consult a landlord-tenant attorney if you're uncertain about your property's status.

Properties Covered by AB 1482

If none of the exemptions apply, AB 1482 governs your rent increases. This includes most apartment complexes, multi-family buildings built before the 15-year rolling window, and single-family homes without proper exemption notices.

How to Calculate the Allowable Rent Increase

AB 1482 limits annual rent increases to 5% plus local CPI, with a maximum of 10%. Calculating the correct amount requires three pieces of information: current rent, local CPI, and the timing of your last increase.

Step 1: Find the Applicable CPI

California uses regional CPI figures published by the California Department of Industrial Relations. For Placer and Sacramento County landlords, the relevant CPI is typically the San Francisco-Oakland-Hayward metro area CPI or the Riverside-San Bernardino-Ontario metro area, depending on the calculation period.

The California Department of Industrial Relations publishes an annual rent increase calculator at www.dir.ca.gov that automatically applies the correct regional CPI. Use this official tool to confirm your calculation.

For 2025-2026, the allowable increase for most Northern California counties has been in the range of 8-10%, reflecting elevated CPI figures. Check the official calculator for the precise figure applicable to your property's location and the date your notice takes effect.

Step 2: Apply the Formula

The formula is straightforward:

• Maximum increase = 5% + local CPI (capped at 10%)
• Example: If local CPI is 4.2%, the maximum increase is 5% + 4.2% = 9.2%
• Example: If local CPI is 6.5%, the formula gives 11.5% but the cap limits you to 10%

Apply this percentage to the current monthly rent:

• Current rent: $2,400/month
• Allowable increase at 8.5%: $2,400 × 0.085 = $204
• New rent: $2,604/month

Step 3: Check the 12-Month Rule

AB 1482 limits landlords to two rent increases per year, but the total of all increases within any 12-month period cannot exceed the maximum allowed percentage. If you raised rent 4% six months ago, you can only raise it by an additional amount that keeps the total within the annual cap.

Track all rent increases by date and amount to avoid inadvertently exceeding the cap through multiple smaller increases.

Rent Increase Notice Requirements

Even if your rent increase calculation is correct, a procedurally defective notice can invalidate the increase entirely.

Notice Period Requirements

• Increases of 10% or less: Minimum 30 days written notice before the increase takes effect
• Increases over 10% (in jurisdictions where this is possible): Minimum 90 days written notice

AB 1482 caps increases at 10%, so landlords following state law will always use the 30-day notice period. However, some local ordinances allow increases above 10% in limited circumstances, requiring 90 days.

What the Notice Must Include

California law doesn't specify a particular form, but a valid rent increase notice should include:

• Property address
• Tenant name(s)
• Current monthly rent amount
• New monthly rent amount
• Effective date of the increase (must be at least 30 days after service)
• Date the notice was prepared/served
• Landlord or property manager signature

Keep a copy of every notice you serve. If a dispute arises later, you'll need to prove what you sent and when.

Timing Relative to Lease Terms

For month-to-month tenancies, a properly served 30-day notice takes effect at the end of the next rental period that begins at least 30 days after service. For fixed-term leases, you generally cannot raise rent during the lease term unless the lease explicitly allows it. Plan rent increases to coincide with lease renewals or the transition to month-to-month.

How to Properly Serve a Rent Increase Notice

California law specifies acceptable methods for serving tenant notices. Using the wrong method can invalidate your notice even if the content is correct.

Acceptable Service Methods

• Personal delivery: Hand the notice directly to the tenant. Most reliable method—use when possible. Document with date and signature if the tenant will accept one.
• Substituted service: Leave with another adult at the residence AND mail a copy the same day
• Posting and mailing: Affix notice to main entry door AND mail a copy — adds 5 days to the notice period
• Certified mail: Generally acceptable but adds time; confirm tenant actually receives it

Document Your Service

Create a proof of service document for each notice, recording:

• Date and time of service
• Method of service used
• Name of person served (or description of posting location)
• Address where notice was served
• Your name and signature

This documentation protects you in any dispute about whether proper notice was given.

Local Rent Control Ordinances

AB 1482 sets a statewide floor of tenant protections. Cities and counties can—and many do—impose stricter rent control ordinances with lower caps or additional requirements.

Sacramento Area Local Rent Control

The City of Sacramento has its own rent stabilization ordinance that applies to certain multi-family units. Sacramento's local ordinance may cap increases below AB 1482's statewide formula for covered units. If you own property in the City of Sacramento, verify whether your unit falls under the local ordinance before serving any rent increase notice.

Placer County

As of 2026, Placer County cities including Roseville, Rocklin, Lincoln, and Auburn do not have local rent control ordinances more restrictive than AB 1482. Landlords in these areas follow the statewide formula. However, local laws can change—always verify current requirements before serving a rent increase notice.

What This Means in Practice

If your property is in a jurisdiction with local rent control, you must follow whichever rule is more protective of the tenant. This means if local ordinance limits increases to 3% but AB 1482 would allow 8%, you can only increase by 3%. Local rent control ordinances are separate from just cause eviction protections and may have their own notice requirements.

When Should You Raise Rent?

Having the legal right to raise rent and knowing when to do so strategically are different questions. Timing rent increases well preserves tenant relationships while maximizing your investment returns.

At Lease Renewal

The most natural time to raise rent is at lease renewal. Send the new lease agreement with the increased rent amount 60-90 days before expiration. This gives tenants time to decide and gives you time to find replacement tenants if they choose not to renew. For guidance on the full renewal process, see our Placer County Tenant Placement Guide.

Market Conditions Matter

Just because you can raise rent doesn't mean you should raise it to the maximum. Consider:

• Current vacancy rates: A tight market (under 4% vacancy) supports aggressive increases; a soft market makes increases riskier
• Tenant quality: Long-term, responsible tenants who pay on time and care for the property are valuable. A 10% increase that causes a great tenant to leave may cost more in turnover than the raise generated
• Your property's condition: A rent increase is easier to justify after making upgrades or improvements
• Comparable rents: If similar properties rent for significantly more than you're charging, an increase is clearly warranted

Our Placer and Sacramento Rental Pricing Guide provides current market benchmarks to help you determine whether your rent is at, above, or below market.

Annual vs. Strategic Increases

Some landlords raise rent automatically every year up to the legal maximum. Others raise rent less frequently but in larger increments. Both approaches can work, but consider the tenant relationship. Annual increases—even modest ones—can feel relentless to tenants. A larger, less frequent increase, or a clear communication about why the rent is going up, often lands better than silent incremental raises.

How Tenants May Respond

Understanding how tenants typically respond to rent increases helps you manage the process more effectively.

Acceptance

Most tenants who receive a reasonable, legally proper rent increase simply accept it, particularly if they've been happy in the property. The cost and disruption of moving often outweighs a moderate rent increase. Tenants who have been in a property for several years and are below market often accept increases even approaching the maximum.

Negotiation

Some tenants will negotiate, particularly if they've been good tenants for many years or if they have concerns about market alternatives. This is often a healthy conversation. You might agree to a smaller increase in exchange for a longer lease term, or consider phasing a larger increase over two years. Good tenants are worth modest concessions.

Notice to Vacate

Some tenants will respond to rent increases by giving notice to vacate, especially if the market has moved against them or they were already considering leaving. This isn't necessarily bad news—it may open an opportunity to lease at current market rates. Have your turnover process ready. See our guides on California Tenant Screening and Rental Property Inspection for move-out best practices.

Dispute or Challenge

Occasionally tenants will challenge a rent increase, claiming it violates AB 1482 or local rent control. Having documentation of your calculation, proper notice, and service method is your best protection. If a tenant refuses to pay the increased rent and you're confident in your legal position, consult a landlord-tenant attorney before taking further action.

Common Rent Increase Mistakes

Even experienced landlords make errors in the rent increase process. Avoid these common pitfalls.

Increasing Rent Without Checking Exemption Status

Some landlords with technically exempt properties apply AB 1482 limits unnecessarily. Others believe they're exempt when they're not—particularly those who missed the required statutory notice for single-family homes. Verify your property's status before every increase cycle.

Miscalculating the CPI Component

Using the wrong CPI index, an outdated figure, or applying it incorrectly produces an invalid increase. Always use the California DIR's official calculator and document the CPI figure you used and when you retrieved it.

Insufficient Notice Period

Serving a 30-day notice but making it effective only 28 days later—because you forgot to count the mailing period—invalidates the increase. When in doubt, give yourself extra buffer on the notice period.

Raising Rent During a Fixed-Term Lease

Unless the lease explicitly allows mid-term increases, raising rent during a fixed-term lease violates the contract. Wait for the lease to expire or convert to month-to-month before implementing increases.

Exceeding the Annual Cap Across Multiple Increases

If you implement two increases in one year, they must together stay within the AB 1482 cap for that 12-month period. Many landlords raise rent once at lease renewal without this being an issue—but those who raise rent mid-tenancy need to track the rolling 12-month total carefully.

Not Keeping Records

If a tenant disputes the increase or files a complaint with a local rent board, you'll need documentation of your calculation, the notice, and proof of service. Keep these records for at least three years after the tenancy ends.

Sample Rent Increase Notice Language

While you don't need to use a specific form, here's language you can adapt for a compliant California rent increase notice:

---

NOTICE OF RENT INCREASE

Date: [Date]

To: [Tenant Name(s)]
Property Address: [Full Address]

This notice is to inform you that effective [Effective Date—at least 30 days from service], your monthly rent will increase from $[Current Amount] to $[New Amount] per month.

This represents an increase of [X]%, calculated in accordance with California Civil Code § 1947.12 (AB 1482). The applicable CPI for [your region] for this period is [X]%, resulting in a maximum allowable increase of [X]%.

All other terms and conditions of your rental agreement remain in effect.

If you have any questions, please contact [Landlord/Property Manager Name] at [Phone/Email].

Sincerely,
[Landlord/Property Manager Name]
[Contact Information]

---

Adapt this template to your specific circumstances. Have a landlord-tenant attorney review your notice process if you have questions about compliance.

Raising Rent the Right Way Protects Your Investment

California's rent increase rules exist to balance landlord property rights with tenant stability. Working within these rules—rather than around them—produces better outcomes for everyone. Tenants who feel fairly treated are more likely to renew, take care of the property, and communicate proactively about maintenance issues.

For most Placer County landlords, the rent increase process is straightforward: calculate the allowable amount using the DIR tool, serve written notice at least 30 days in advance, document everything, and keep the increase reasonable relative to what the market supports.
