Check the ceiling before the figure
Most states impose no statewide limit, so look to the city or county. Where a local cap exists it commonly allows 3-10% over 12 months, and CPI-indexed caps change from year to year.
How much can rent rise?
In most of the United States no statewide law caps a rent increase, so the real ceiling is set by the city or county — where caps exist they commonly allow 3-10% over 12 months, often indexed to CPI. The increase must also be announced in writing ahead of time: 30 days is the common baseline, 60-90 days for larger raises, and California splits the requirement at a 10% increase. This page walks through the cap check, the day count, and the fee and deposit limits that sit around the rent.
Start with the figures
Scroll the strip sideways — 6 cards.
Most states impose no statewide limit, so look to the city or county. Where a local cap exists it commonly allows 3-10% over 12 months, and CPI-indexed caps change from year to year.
Thirty days' written notice is the baseline for month-to-month tenancies. Larger increases and longer tenures push the requirement to 60-90 days, and California demands 90 above a 10% raise.
An increase takes effect on the first day of a rental period, not mid-month. A notice served late does not accelerate the increase — it slides it to the next cycle.
A grace period of about five days is customary but binds only if the lease states it. Where the fee is regulated, it commonly caps at 5-10% of the monthly rent or must track actual damages.
Deposit caps commonly run one to two months' rent where they exist. At move-out, deductions must be itemized in a statement typically due within 14-30 days.
Before a notice to quit can be served, most jurisdictions require a written rent demand giving 3-14 days to pay. Filing without it is the defect that dismisses cases.
No dated events belong on this chart; the standing periods — 30-90 days of notice, 3-5 days of grace, 14-30 days to itemize — are the only timeline the rules set.
| What is limited | Typical figure | Where it applies |
|---|---|---|
| Rent increase over 12 months | 3-10%, often CPI-indexed | Cities and counties that cap rent; most states have no statewide limit |
| Notice, increase of 10% or less | 30 days, written | California (Civil Code section 827); common baseline elsewhere |
| Notice, increase above 10% | 90 days, written | California (Civil Code section 827) |
| Notice, month-to-month under one year | 30 days, effective next rent cycle | Common baseline across jurisdictions |
| Late-fee grace period | 3-5 days | Customary; binding only if the lease states it |
| Late fee | 5-10% of monthly rent | Where the state regulates the fee; otherwise actual damages |
| Security deposit | 1-2 months' rent | Where a state sets a cap; several fix one month, others set none |
| Itemized deduction statement | Due within 14-30 days of move-out | Typical statutory window |
Most states set no statewide limit, so the binding cap — if any — is local.
The majority of US states have no statewide rent control, which means a landlord renewing a lease there can propose any new figure the market will bear. The exceptions are local: cities and counties that do cap increases commonly allow between 3% and 10% over a 12-month period.
Many local caps are indexed to the consumer price index, so the permitted percentage moves year to year. A cap that allowed 7% last year may allow less this year, which is why the current local figure must be re-checked before any notice is served — these rates change frequently.
Size can also trigger procedure even where no cap exists. In California an increase of 10% or less within 12 months needs 30 days' written notice, while anything above 10% needs 90 days under Civil Code section 827 — the bigger the raise, the longer the runway the law requires.
Thirty days in writing is the baseline; larger increases and longer tenures push it to 60-90.
For a month-to-month tenancy shorter than one year, 30 days' written notice effective on the next rent cycle is the common baseline across jurisdictions. The notice must arrive before the rental period in which the new rent would first be charged.
Many jurisdictions stretch the requirement to 60 or 90 days when the increase is large or the tenant has been in place longer. California's split is the clearest example: 30 days for an increase of 10% or less, 90 days for anything above 10%.
Whatever the period, the notice has to be written. A verbal mention or a text message does not start the clock, and an increase announced late simply slides to the following rent cycle rather than taking effect mid-period.
Every figure on this page is drawn from a published statute — such as California Civil Code section 827 — or from a baseline used across many jurisdictions, and each is labelled as fixed or changing. Where a rate is set locally or indexed to CPI, the page says to re-check the current figure rather than trust a memorized one. No figure here comes from a lease template, a brokerage, or a private source.
Where these figures come from
The list behind these numbers is short on purpose: state statutes such as California Civil Code section 827, plus the common jurisdictional baselines described on this page, with local ordinances re-checked at the time of use.
