Rent Increase Notice in California
How many days of advance notice a landlord must give before a rent increase takes effect in California, how a fixed-term lease is treated, and what to check, cited to the statute.
The notice periods in California
How much warning is required before a higher rent can take effect, and how a fixed lease is treated.
| When | Notice in California | What it means |
|---|---|---|
| Increase of 10% or less | 30 days | At least 30 days written notice if the increase, added to any other increases in the past 12 months, is 10% or less of the rent charged during that period. |
| Increase of more than 10% | 90 days | At least 90 days written notice if the increase, cumulative over the past 12 months, is more than 10%. |
| Fixed-term lease | None mid-term | During a fixed-term lease the rent is locked at the agreed amount. A landlord can raise it only when the term ends and the tenancy renews or converts to month-to-month. |
| If mailed | Add days | If the notice is mailed rather than handed over, California adds extra days under Code of Civil Procedure §1013 (commonly 5 days for in-state mail), so a mailed notice must be sent that much earlier. |
| Limit on the amount | Separate rule | California also limits how much rent can rise each year for many units, under the Tenant Protection Act of 2019. That amount limit is a separate rule that moves with inflation, so this notice page does not state a figure for it. |
| If notice is skipped | Not effective | A rent increase is not effective until proper notice has run. If a landlord raises the rent without the correct 30 or 90-day notice, the tenant still owes only the old rent until a valid notice takes effect. |
| Statute | Cal. Civ. Code §827(b) | The controlling statute for this notice period. Read the full text through the source link below. |
The 30-day and 90-day notice periods have been stable, but the separate Tenant Protection Act cap on the amount is recalculated each year, which is why this page tracks only the notice days.
Next steps if your rent is going up
Concrete, neutral steps to check a rent increase in California. This is legal information, not legal advice.
- Check the notice period against the size of the increase
Add up any rent increases over the past 12 months. If the total is 10% or less, the landlord needs at least 30 days notice; if it is more than 10%, at least 90 days. Count from the date the notice was properly served.
- Add mailing time if it came by post
If the notice arrived by mail, California adds extra days on top of the 30 or 90. That can push the earliest lawful effective date later than the date printed on the notice.
- Confirm you are not in a fixed lease
If you are still inside a fixed-term lease, the rent cannot go up until the term ends, unless your lease specifically allows a mid-term increase. Read your lease before paying a higher amount.
- Get California rent-increase help
The California Courts self-help center explains rent-increase notice and the separate Tenant Protection Act limits. A local tenant-rights group or rent board can check whether your increase is both properly noticed and within any cap.
If your rent is going up, you can check whether the notice was proper and whether any limit applies. This resource explains your rights.

What California renters get wrong
California is one of the few states with a dedicated rent-increase notice rule, and the number of days depends on the size of the increase. Under Civil Code §827(b), a landlord raising the rent on a month-to-month tenancy must give at least 30 days written notice when the increase is 10% or less of the rent charged over the previous 12 months, and at least 90 days when it is more than 10%. The 10% figure is easy to misread: it does not cap the rent, it only decides which notice period applies. Two details trip renters up. If the notice is mailed instead of handed over, California adds extra days under Code of Civil Procedure §1013, so the real effective date is later than the one on the paper. And inside a fixed-term lease the rent is simply locked until renewal. California also limits how much rent can rise for many units under the Tenant Protection Act, but that cap is a separate, inflation-linked rule, so this page sticks to the one thing that stays stable: the notice you are owed.
Common questions
How much notice for a rent increase in California?
On a month-to-month tenancy, at least 30 days written notice if the increase is 10% or less of the rent charged over the past 12 months, and at least 90 days if it is more than 10% (Civil Code §827(b)). If the notice is mailed, extra days are added.
What does the 10% rule mean for California rent increases?
The 10% figure decides which notice period applies, not how much the rent can go up. An increase of 10% or less over the trailing 12 months needs 30 days notice; a larger increase needs 90 days. A separate law, the Tenant Protection Act, limits the amount for many units.
Can my landlord raise rent during a lease in California?
No, not during a fixed-term lease, unless the lease itself allows a mid-term increase. The agreed rent is locked until the term ends. Rent-increase notice rules apply to month-to-month tenancies and at renewal, not to the middle of a fixed term.
Does a mailed rent-increase notice give me more time in California?
Yes. If the landlord mails the notice rather than delivering it in person, California adds extra days under Code of Civil Procedure §1013, commonly 5 days for in-state mail. So a mailed 30-day notice effectively runs longer, and the increase cannot start until that full period passes.
Is there a limit on how much rent can go up in California?
For many units, yes, under the Tenant Protection Act of 2019, but that is a separate rule from the notice requirement and its figure changes with inflation each year. This page covers only the notice days, which are stable. Check your local rent board or a tenant-rights group for the current amount limit.
