How to Handle a Lease Renewal the Right Way in California (2026)

The notice requirements, rent increase rules, AB 1482 caps, and operational steps that keep Central Valley landlords compliant and their tenants renewing.

Lease renewal season is where landlords either run a professional operation or discover they've been running a risky one. The difference is usually not malicious — it's that California's renewal rules are more specific than most landlords realize, and the consequences of getting them wrong range from an invalid rent increase to genuine legal exposure.

This guide walks through the renewal process the right way: what the law requires, what landlords most commonly get wrong, and what good operational practice looks like at renewal time.

First: Understand What Happens When a Lease Expires

Before getting into the mechanics, it's worth clarifying what California law actually says about a lease that reaches its end date — because a common landlord assumption here is wrong.

When a fixed-term lease expires and the landlord accepts rent from the tenant, California Civil Code §1945 treats the tenancy as automatically converted to a month-to-month arrangement on the same terms as the original lease. The tenant doesn't have to sign anything for this to happen. The moment you cash or deposit that first rent payment after the lease end date, a new month-to-month tenancy exists.

This matters for several reasons. First, the notice requirements are different for month-to-month tenancies than for fixed-term leases. Second, once a tenancy converts to month-to-month and meets the AB 1482 residency threshold, just-cause protections apply in a different way than they do during the fixed term. Third, it means there's no automatic deadline that forces the tenant out — a lease "expiring" in California doesn't terminate the tenancy if you keep accepting rent.

The practical implication: don't assume a lease expiration date is a natural end point. Plan your renewal conversation well before the end date so you're managing the process deliberately rather than reacting to it.

The Renewal Timeline That Actually Works

The landlords who handle renewals well aren't doing anything complicated. They're starting the conversation at the right time.

90 days before lease expiration: This is when a professional landlord begins the renewal outreach. A 90-day window gives you time to assess whether you want to renew (and on what terms), give the tenant time to make a decision, and if you're increasing rent, serve proper notice well before the effective date. Starting at 90 days also gives you flexibility: if the tenant decides not to renew, you have time to market the property, screen applicants, and execute a new lease without a vacancy gap.

60 days before expiration: If you haven't heard back from the tenant or haven't reached agreement on renewal terms, this is the escalation point. For tenants who have lived in the property 12 months or longer, California law requires 60 days written notice to change tenancy terms or terminate — so this is your deadline if you need to give formal notice.

30 days before expiration: For tenants with less than 12 months of residency, 30 days written notice is required. This is also the standard notice period for rent increases of 10% or less (more on that below).

The single most common operational failure in lease renewals is starting too late. A landlord who reaches out 30 days before expiration with a rent increase, a new lease document, and an expectation that the tenant will sign and continue is often too late to be legally compliant — and is definitely too late to preserve a good tenant relationship.

Rent Increases at Renewal: The Rules That Matter

If you're increasing rent at renewal time, California law is specific about how you do it — and there are two distinct frameworks depending on whether your property is covered by AB 1482.

The Notice Period Rules (All Properties)

California Civil Code §827 sets the baseline notice requirements for rent increases:

• 30 days written notice for increases of 10% or less of the lowest rent charged in the prior 12 months.
• 90 days written notice for increases exceeding 10%.

Two points that landlords frequently get wrong here:

First, the 10% threshold is calculated against the lowest rent charged in the prior 12 months — not the current rent. If you gave a discount at any point in the year, the baseline for the threshold calculation is that lower number.

Second, if you've given any other rent increase within the same 12-month period, the two increases are added together for purposes of the threshold calculation. Two increases of 6% each don't each get their own 30-day notice — combined, they're 12%, which requires 90 days.

The effective date of the increase must be at least 30 (or 90) days after the notice is served — not 30 days after you mailed it, and not 30 days after the lease expiration date. Count backward from the effective date you want, not forward from when you decide to act.

AB 1482 Properties: The Cap That Applies

For properties covered under California's Tenant Protection Act (AB 1482), rent increases are capped annually at the lower of:

• 5% plus the local CPI, or
• 10% flat

For the Sacramento/Central Valley CPI region, the allowable cap as of August 1, 2026 is 8.8% — up from the 6.3% cap that applied through July 31. This is the ceiling, not a target. In a market where rents are flat to slightly declining, a full 8.8% increase on a stable long-term tenant carries meaningful turnover risk. The strategic question is what increase retains the tenant and improves your net operating income — not what the law allows.

Which Properties Are Covered Under AB 1482

AB 1482 covers most residential rentals in California but has several important exemptions. Single-family homes and condos may be exempt — but only if the owner has provided the required written exemption notice to the tenant, as specified in Civil Code §1946.2(e)(8)(B)(i). If that language isn't in the lease, the property may be treated as covered even if it would otherwise qualify for exemption.

Properties built within the last 15 years are exempt from AB 1482 regardless. Owner-occupied duplexes are also exempt.

If you're unsure whether your property is covered, confirm before your next renewal cycle — not after you've already served a rent increase notice that may exceed the cap.

The New Requirement Landlords Are Missing: AB 1414

Starting January 1, 2026, if your lease includes bundled internet service as part of the rent, California law now requires that tenants have the right to opt out of that bundled service. If the lease doesn't include that opt-out right, tenants may deduct the cost of their own separately-obtained internet service from rent.

For most Central Valley landlords, this doesn't apply — bundled internet in a lease is more common in larger multifamily buildings. But if you've included internet access in your lease terms, this is a compliance update you need to address at renewal.

The Renewal Document: Addendum vs. New Lease

When renewing an existing tenancy, most landlords are better served by a lease renewal addendum than a full new lease document. The addendum references the original lease, updates the term and rent, and incorporates any changed terms — without requiring you to reproduce the entire original document.

The practical benefits: it's faster, it's cleaner, and it clearly identifies what's changing versus what carries forward from the original agreement.

If you do execute a new lease, make sure all original disclosures carry forward. AB 1482 notices, single-family exemption language where applicable, lead paint disclosures for pre-1978 properties, and any other required disclosures from the original lease need to appear in or be incorporated into the new document.

The Notice Itself: Service Requirements

A rent increase notice or lease change notice must be delivered in writing and served properly. California law accepts three methods:

Personal delivery to the tenant directly.

Substituted service — leaving the notice with someone of suitable age at the residence and mailing a copy to the address. The notice period begins running when the mailing is complete, not when it's left with the other person.

Certified mail with return receipt. The notice period begins running when the notice is deposited with the postal service.

Verbal notice, text message, and email do not satisfy the statutory requirement unless the tenant has separately agreed in writing to accept notices electronically. Don't skip the paper.

Common Mistakes That Void Notices or Create Liability

A short list of errors that landlords make more often than they should:

Serving the rent increase notice simultaneously with the new lease. These are separate legal events on separate timelines. The increase notice must precede the effective date by the required period. If you hand a tenant a new lease and a rent increase notice on the same day, the notice period may not be satisfied.

Using the lease expiration date as the notice clock. The 30- or 60-day notice period runs from when the notice is served, counted forward to the effective date of the change — not backward from the lease end date.

Assuming lease expiration terminates the tenancy. As noted above, accepting rent after a lease expires creates a month-to-month tenancy. If you want the tenancy to end at lease expiration, you need to give proper notice and not accept any post-expiration rent.

Missing the AB 1482 exemption notice. Landlords with single-family rentals that qualify for the AB 1482 exemption but didn't include the required language in their original lease are operating under the cap whether they realize it or not.

Increasing rent above the cap on a covered property. An increase that exceeds the AB 1482 limit is not just an error — it exposes the landlord to tenant claims and potential liability. Know your cap before you serve any notice.

The Retention Conversation Most Landlords Skip

Beyond the legal mechanics, there's an operational practice that distinguishes the landlords who build stable, low-turnover portfolios from the ones who are perpetually filling vacancies.

The renewal conversation — not the notice, the conversation — should happen at 90 days. It doesn't have to be complicated. A simple outreach that says: here's the lease end date, here's what we're thinking for the renewal term and rent, we value you as a tenant and want to make this easy — that communication sets a different tone than a formal notice arriving 30 days before expiration with a rent increase the tenant wasn't expecting.

Tenants who feel respected stay longer. Tenants who feel managed leave at the first opportunity. In a market where a vacancy event costs one to two months of lost rent plus make-ready costs, the landlord who starts renewal conversations early and communicates transparently about any increase is almost always ahead financially compared to the one who maximizes rent on paper and absorbs the turnover.

The Renewal Checklist

Before every lease renewal cycle, run through these:

Know your property's AB 1482 status — covered, exempt with proper notice, or newly built and outside coverage.

Verify the current allowable cap for the Sacramento/Central Valley CPI region (8.8% as of August 1, 2026).

Check whether the single-family exemption notice is in the original lease if applicable.

Set calendar reminders at 90 and 60 days before lease expiration — not 30.

Decide on the renewal term and any rent adjustment before reaching out to the tenant.

Serve any rent increase notice as a standalone document, separately from the renewal lease or addendum.

Count the effective date of the increase backward from the notice service date — 30 days minimum for increases at or under 10%, 90 days for increases over 10%.

Document proof of service for every notice you deliver.

Handled well, lease renewal is the moment a landlord reinforces why a good tenant should stay. Handled poorly, it's the moment you lose them.
