Short answer
A fixed-term lease locks in the tenant, the rent and the end date, which suits owners who want steady income. Month-to-month gives both sides flexibility, but you need 60 days' notice to end it once everyone has lived there a year. After 12 months, a home covered by the Tenant Protection Act needs a just cause to end the tenancy under either option, so the lease end date alone is not a reason.
The question usually shows up at the first renewal
Your tenant's first year in your Rocklin home is almost up. They pay on time and want to stay, but they ask about going month to month because their job might move. Or you are the one unsure, because you might sell next year or move back after a work assignment.
Both choices are legal and common. They differ in who is locked in, how the rent can change and how the tenancy ends. California law treats them differently in a few places that matter a great deal, and it treats them the same in one big place: just cause after 12 months.
How each option works
A fixed-term lease runs for a set period, such as six months or a year, and the tenant is bound until it expires. The state's landlord-tenant guide notes that during the term the landlord cannot raise the rent unless the lease expressly allows increases, and a tenant who leaves early could owe rent until the term ends or the home is re-rented (DRE guide). Civil Code 1951.2 limits that claim to rent the tenant cannot show you could reasonably have avoided, so you are expected to try to re-rent.
A month-to-month tenancy renews itself each month until someone gives proper written notice. The tenant can leave with 30 days' notice. Your notice depends on how long the tenant has been there (Civil Code 1946.1):
- 60 days once every tenant or resident has lived in the home for a year or more.
- 30 days if any tenant or resident has lived there less than a year.
- 30 days in a narrow sale case: an opened escrow, a buyer who is a natural person and intends to live there at least a year, notice within 120 days of escrow opening, and the other conditions in 1946.1(d).
- In every case, a covered tenancy past 12 months also needs a just cause stated in the notice, and you may not charge the tenant a fee for serving it.
What happens on the last day of a lease
If the tenant stays after the lease expires and you accept rent, Civil Code 1945 presumes the lease renewed on the same terms, for no longer than one month at a time when rent is paid monthly. In practice, an expired lease with rent still coming in often becomes a month-to-month tenancy. Read your lease, because many leases also say in writing what happens at the end.
What the end date does not do is end the tenancy by itself in a covered home. Once the tenant has lived there 12 months, the owner may end the tenancy only for a just cause listed in Civil Code 1946.2, and an expiring lease is not on that list. If an adult is added to the household before any tenant reaches 24 months, protection starts when all tenants have 12 months or one tenant has 24.
| If this is you | What usually fits | What to check first |
|---|---|---|
| You want steady rent and plan to keep the home for years | A fixed term, renewed with a new term each year | A rent figure you can live with for the whole term |
| You might move back into the home | Either option, with an owner move-in clause in the lease | Move-in within 90 days of the tenant leaving and 12 months' occupancy |
| You may sell within a year | Either option; a sale alone is not a just cause | Whether the 1946.1(d) sale exception could apply to your buyer |
| Your tenant's job may relocate them | Month-to-month, with the tenant's 30-day notice | Your own 60-day notice period once they pass a year |
| Your home is exempt and the notice is in the lease | Either option, with more flexibility at the end | The exact statutory exemption wording, word for word |
Just cause makes the two options closer than they look
Many owners pick month-to-month expecting to get the house back on 60 days' notice. For a home covered by the Tenant Protection Act, that works only with a just cause. The at-fault causes include nonpayment, a material lease breach, nuisance and refusing lawful entry. The no-fault causes are owner or close-family move-in, withdrawing the home from the rental market, a government order and a substantial remodel, and each no-fault ending requires one month's rent as relocation help or a written waiver of the final month's rent.
Two details tie directly to your lease choice. First, a tenant's refusal to sign a written extension or renewal of similar length and terms, at your request, is an at-fault cause, so offering a fair new fixed term has legal weight. Second, for leases signed on or after July 1, 2020, owner move-in works only if the tenant agrees in writing or the lease contains a clause allowing it. If you might move back, that clause belongs in the lease now.
Some single-family homes and condos are exempt when the owner is not a corporation, a REIT or an LLC with a corporate member and the exact statutory notice is in the lease. The rent increase guide covers that notice. Even an exempt home still follows the 1946.1 notice periods.
How rent changes under each option
Under a fixed-term lease, the rent usually stays put until the term ends unless the lease allows an increase. At renewal you can set the new rent within any limits that apply. Under month-to-month, you can raise rent with written notice under Civil Code 827: at least 30 days if the increase, combined with others in the prior 12 months, is 10 percent or less of the rent, and at least 90 days if it is more.
For a covered home, the state rent cap applies under both options, and the rent can be raised in no more than two increments in a 12-month period. One 2026 change applies only to month-to-month tenants: under Civil Code 1942.8, they may opt out of paying for a landlord-arranged third-party internet subscription. If your rent includes a bundled internet plan, factor that in before moving a tenant to month-to-month.
Choosing, and planning the renewal
A fixed term tends to fit owners who want predictable income, plan to hold the home for years and like a scheduled moment to review rent and terms. Month-to-month tends to fit a tenant whose plans are uncertain, or an owner who values flexibility and understands that just cause still limits how the tenancy ends.
Either way, start the renewal conversation well before the end date, so you have time to send a 60-day notice if a lawful reason applies, or to offer a new lease the tenant can review. Check the lease for an owner move-in clause, the Tenant Protection Act notice or exemption language, and the rent figures listed separately from any discount. SPMG's lease renewals page describes market analysis, new lease agreements and paperwork at renewal, and the rental leasing page covers lease preparation for a new tenant. When a tenancy does end, the move-out and deposit checklist walks through the steps that follow.
Common questions
Does a lease automatically turn into month-to-month in California?
Often, yes. If the tenant stays after the lease expires and you accept rent, Civil Code 1945 presumes the lease renewed on the same terms for no more than one month at a time when rent is monthly. Your lease may also say what happens at the end. Either way, the tenant's just cause protection under the Tenant Protection Act carries over if the home is covered.
Can I end a month-to-month tenancy with 30 days' notice?
Only if a tenant or resident has lived there less than a year, or in the narrow sale situation in Civil Code 1946.1(d). Otherwise the owner's notice is at least 60 days. If the home is covered by the Tenant Protection Act and the tenant has passed 12 months, the notice must also state a just cause, and no-fault causes require relocation help or a final-month rent waiver.
Can I raise the rent in the middle of a one-year lease?
Generally not, unless the lease expressly allows increases during the term. The state's landlord-tenant guide makes the same point. Plan rent changes for the renewal date instead. When you do raise rent, a covered home stays within the state cap and the limit of two increases in 12 months, and a month-to-month increase needs 30 or 90 days' written notice under Civil Code 827.
What if my tenant refuses to sign a new lease?
In a covered home, a tenant's refusal to sign a written extension or renewal of similar length and terms, after you ask, is listed as an at-fault just cause in Civil Code 1946.2. The new lease cannot add terms that break the law, and the termination notice still has to follow the statute. Many owners simply let the tenancy continue month to month instead.
