Renewal season creates several different decisions: whether to continue the tenancy, whether to offer a new fixed term, whether the existing lease converts to month-to-month, and whether any rent, service, occupant, insurance, or operational term should change. Those decisions should not be collapsed into one form.
The right next step depends on the current lease, tenancy type, occupancy history, property ownership, location, and the term the owner wants to change.
The short answer
A fixed-term lease generally is not amended unilaterally during its term unless the lease or a specific law permits the change. The parties can sign a written amendment or replacement lease.
For a periodic tenancy, Civil Code section 827 provides a written-notice mechanism for changing terms. A month-to-month change under section 827 generally takes effect on not less than 30 days’ notice, but rent increases have separate 30- or 90-day statewide timing rules and may be limited or require longer notice under other law.
Allowing a fixed term to expire is not always enough to recover possession. State and local just-cause rules can apply to a nonrenewal or termination.
Start with five questions
- Is the tenancy fixed-term, month-to-month, week-to-week, or unclear?
- What does the current lease say about expiration, renewal, and holdover?
- Is the property covered by state or local rent and just-cause rules?
- Is the proposed change a rent increase, decrease in housing service, fee, occupancy rule, or other material term?
- Does the owner want continuation, a negotiated new term, or possession?
The answer determines whether the owner needs an amendment, renewal agreement, section 827 notice, rent-increase notice, termination analysis, or a combination.
Fixed-term lease changes
During a fixed term, the clearest method is a written agreement signed by the parties. An amendment should:
- Identify the original lease and property.
- State the exact clause being changed.
- Give an effective date.
- Address any one-time payment, deposit, credit, or prorating.
- Confirm which provisions remain unchanged.
- Be signed by every owner-side party and every tenant whose obligations change.
- Include any required disclosure or translated copy.
Do not use a periodic-tenancy change notice as a shortcut to rewrite a fixed lease. Also avoid informal side agreements that conflict with the lease, especially about rent, occupants, pets, access, repairs, parking, or early termination.
Renewing or extending a fixed term
A renewal should be treated as a new compliance event. Review:
- Current required disclosures and statutory notices.
- Rent-cap and local rent-increase rules.
- Just-cause coverage and exemption language.
- Changes in ownership entity or authorized manager.
- Occupants, pets, parking, storage, utilities, and services.
- Security-deposit records and any proposed additional security.
- Repair history and unresolved accommodation requests.
- Required translation under Civil Code section 1632 when applicable.
Do not simply change the dates on an old form. A clause that was lawful when first signed may be incomplete or inconsistent with current law.
California’s Tenant Protection Act treats a covered tenant’s refusal, after a written request or demand, to sign a renewal for a similar duration with similar lawful terms as a potential at-fault just cause. That is a specific rule, not permission to use a materially harsher “renewal” to force a tenant out.
What happens when the fixed term expires
Civil Code section 1945 creates a presumption that when a tenant remains after the term and the landlord accepts rent, the hiring is renewed on the same terms, subject to statutory duration limits. With monthly rent, the presumed renewal does not exceed one month.
The lease may also contain a holdover or automatic-renewal clause. Civil Code section 1945.5 imposes conspicuous-type requirements on specified automatic renewal or extension provisions and makes noncompliant provisions voidable by the party who did not prepare the lease.
Before accepting post-expiration rent, decide deliberately:
- Whether the owner is offering a new fixed term.
- Whether the owner accepts a periodic tenancy.
- Whether an exemption or statutory notice must be updated.
- Whether possession is sought and just cause is required.
- Whether local law restricts nonrenewal or requires filings, relocation, or notices.
Acceptance of rent can affect the tenancy and enforcement posture. Do not let accounting automation make that decision silently.
Changing a month-to-month agreement
Section 827 allows a landlord to change terms of a periodic tenancy by a compliant written notice. The notice itself establishes the new terms if the tenant remains after it becomes effective, but that mechanism remains subject to other law.
A change notice should be reviewed for:
- Correct service method.
- Effective date and full notice period.
- Clear identification of the old and new terms.
- Consistency with the existing agreement.
- Rent-cap, fee, fair-housing, habitability, and anti-retaliation limits.
- Local registration, filing, translation, or notice requirements.
Rent increases require separate analysis. Under section 827, an increase of 10 percent or less, measured using the statute’s 12-month lookback, generally requires at least 30 days’ notice; an increase greater than 10 percent generally requires at least 90 days. Civil Code section 1947.12, local rent control, emergency price restrictions, regulatory agreements, and contracts may limit the amount or require a longer period.
A change in a required fee or a reduction in a housing service may be treated as rent under governing state or local law. Labeling the change “not rent” does not determine its legal effect.
Nonrenewal is a termination decision
For an owner ending a periodic residential tenancy, Civil Code section 1946.1 generally uses 60 days’ notice, with a 30-day route when the tenant and every resident have lived there less than one year and a narrow sale-related 30-day route when all statutory conditions are met.
That timing rule does not answer whether the owner has a lawful ground. Civil Code section 1946.2 requires just cause for covered tenancies after its occupancy thresholds are met and imposes detailed requirements for at-fault and no-fault terminations. More protective local ordinances may govern instead.
Accordingly:
- “The lease expired” may not be sufficient.
- “Month-to-month” does not mean terminable for any reason.
- A property-level exemption may depend on ownership and delivery of precise exemption language.
- Local rules may require relocation, agency filing, registration, or different grounds.
Use the month-to-month termination and just-cause guide before delivering a nonrenewal or termination notice.
Local overlay check
The property’s exact address can change the analysis. Cities and unincorporated counties may regulate:
- Annual rent increases and banking.
- Fees and reductions in services.
- Renewal offers and nonrenewal.
- Just-cause grounds and occupancy thresholds.
- Relocation payments.
- Notice language, copies, filings, and service.
- Rental registration or fee status as a condition of enforcement.
- Tenant buyout procedures.
Check city boundaries rather than relying only on the postal city. The Local Landlord Law Center provides the research path for Orange, Los Angeles, and San Diego County properties.
Decision paths
Continue on the same month-to-month terms
Document that choice, verify current notices, and calendar a later compliance review. Do not unintentionally create inconsistent terms through email or rent-ledger labels.
Offer a new fixed term
Prepare a current agreement, explain material changes, give reasonable review time, and preserve delivery and signature records. Verify that the proposal does not conflict with just-cause, rent, or local renewal rules.
Change one periodic term
Use a section 827 analysis and a focused written notice. Do not replace the whole agreement unless a full replacement is intended and lawful.
Change rent
Calculate the 12-month history, statewide cap coverage, local cap, emergency restrictions, and service method. Review the dedicated rent-increase guide.
Seek possession at expiration
Pause before sending “nonrenewal.” Determine coverage, cause, notice period, relocation, filings, and the owner’s evidence.
Common mistakes
- Assuming every fixed term ends automatically for possession purposes.
- Accepting rent after expiration without deciding the holdover status.
- Using 30 days for every periodic change.
- Treating a rent increase as an ordinary term change.
- Adding fees or removing services without rent-control analysis.
- Reusing a stale lease or exemption notice.
- Offering “similar” renewal terms that are materially different.
- Using a renewal decision to mask discrimination or retaliation.
- Ignoring local registration or filing prerequisites.

Questions property owners often ask
Can an owner change a fixed-term lease before it expires?
Usually through a signed amendment or another authority in the lease or law. A unilateral periodic-tenancy notice ordinarily should not be used to rewrite a fixed term.
How much notice is required to change a month-to-month term?
Section 827 generally uses at least 30 days for a month-to-month term change. Rent increases, longer contractual or statutory periods, and local law can require different treatment.
Does a fixed lease automatically become month-to-month?
It can, depending on the lease and conduct after expiration. Section 1945 presumes a renewal when the tenant remains and the landlord accepts rent, with a monthly duration limit when rent is monthly.
May an owner refuse to renew without stating a reason?
Not safely without a coverage analysis. State or local just-cause law may require a permitted ground, precise notice, relocation, or filings even when a fixed term ends.
Can a renewal increase rent and change other terms?
Potentially, but each change must be lawful. Rent caps, notice rules, service reductions, security-deposit limits, fair-housing obligations, and local rules can affect the package.
What if the tenant will not sign the renewal?
The response depends on just-cause coverage and whether the offered term is of similar duration with similar lawful provisions. Preserve the offer and communications and obtain review before serving a termination notice.
Does accepting one rent payment after expiration matter?
It can. Acceptance may support a presumption that the tenancy renewed. Review the lease, payment, communications, and intended status promptly.
