Is That Rent Increase Legal in Your State?

In most states, by any amount, as long as the tenancy is periodic (or up for renewal), proper written notice is given, and the increase is not retaliatory or discriminatory. Only California (5% plus regional CPI, capped at 10%, Civ. Code 1947.12), Oregon (7% plus CPI or 10%, whichever is lower, ORS 90.324; 9.5% published for 2026), Washington (7% plus CPI or 10%, whichever is lower, RCW 59.18.700, since May 2025), and the District of Columbia (rent-stabilized units) cap increases statewide, each with significant exemptions. Local ordinances in New York City, New Jersey cities, St. Paul, and parts of California and Maryland add their own caps where state law allows.

It depends on the state. Common periods for a month-to-month tenancy run from 10 days in Louisiana to 90 days in Oregon and Washington (and 120 days for month-to-month tenants age 62 or older in Rhode Island), with 30 days the most common. Several states scale notice to the size of the increase: California requires 90 days when the increase tops 10% (30 days otherwise), Maine requires 75 days at 10% or more (45 otherwise), and New York requires 30, 60, or 90 days for increases of 5% or more depending on how long you have lived there. The calculator above shows your state's period with the statute cite.

Generally no. A fixed-term lease locks the rent for the term unless the lease itself contains an escalation clause the tenant already agreed to. The landlord's opportunity to raise rent comes at renewal, or on the schedule the statute sets for month-to-month tenancies. If a mid-term increase notice arrives without a supporting lease clause, the existing lease price stays enforceable until the term ends.

Statewide caps exist in California, Oregon, and Washington, plus the District of Columbia's rent stabilization program for covered buildings. No other state caps increases statewide, and more than twenty states affirmatively prohibit their own cities from adopting rent control. The states that allow local rent control account for most of the rest of the map: New York (NYC rent stabilization and the 2024 Good Cause Eviction standard), New Jersey (over one hundred municipal ordinances), Maryland (several counties), Maine (Portland), and Minnesota (St. Paul, by voter approval).

For units covered by AB 1482, the most is 5% plus the regional CPI change, or 10%, whichever is lower, measured over any 12-month period and in no more than two steps (Civ. Code 1947.12). The CPI component is the April-over-April change for your region, so the exact ceiling varies by county and year. Important exemptions: housing first occupied within the last 15 years, and single-family homes or condos owned by individuals (not corporate entities) where the tenant received the written exemption notice. Cities with stricter local rent control, such as Los Angeles and San Francisco, apply their own lower caps to covered buildings.

Subtract the current rent from the new rent, divide by the current rent, and multiply by 100. Example: rent moving from $1,500 to $1,650 is (1,650 - 1,500) / 1,500 x 100 = a 10% increase, which costs the tenant $1,800 more per year. The calculator above does the math and then checks the percentage against your state's cap and notice rules.

You can refuse it, but on a month-to-month tenancy refusal usually ends the tenancy rather than freezing the rent: in most states a properly noticed increase you decline becomes grounds for the landlord to terminate, and in New Hampshire the statute says so expressly (RSA 540:2). Your real options are to negotiate before the effective date, check the increase for defects (short notice, mid-lease timing, an amount over a cap that applies, retaliation), invoke local protections such as a New Jersey rent-leveling board or a Connecticut fair rent commission, or give your own notice and move. In good-cause jurisdictions like New York City, an increase above the local standard can also be challenged in the eviction case itself.

The common defects: short or missing written notice (each state sets the period); a mid-lease increase with no lease clause allowing it; an amount above a statewide or local cap that covers the unit; retaliation for a repair complaint, code report, or tenant-organizing activity (barred in most states); discrimination tied to a protected class under the Fair Housing Act; and in Maine, any increase while the unit violates the warranty of habitability (14 M.R.S. 6016). New Jersey adds a general bar on unconscionable increases. An increase with one of these defects is typically unenforceable until cured, but the rent already agreed to remains owed.

Most states do not limit frequency, only notice, so a landlord could raise rent repeatedly on a month-to-month tenancy if each increase carries proper notice. The exceptions with hard frequency limits: Colorado allows only one increase in any 12-month period regardless of lease type (C.R.S. 38-12-702), Oregon allows one per 12 months and none in the first year (ORS 90.323), Washington caps the total in any 12-month period and bars increases in the first year (RCW 59.18.700), and California allows at most two steps within its 12-month cap (Civ. Code 1947.12).

In nearly every state that regulates the subject, yes: the statutes cited in the table above almost all require written notice, and several (Washington, New Hampshire, Oregon) prescribe what the writing must contain, such as the amount, the effective date, or a statutory form. Even where a statute is silent, a written notice is the only version that survives a dispute, which is why we provide a free rent increase notice template. Oral notice of an increase is a common and usually fatal defect in later eviction cases.

Market practice in most years runs roughly with inflation, and the statutory caps that exist cluster around the same idea: CPI plus a cushion, with a ceiling near 10% (California, Oregon, Washington, and New York's good-cause standard all land there). A landlord pricing a renewal should compare the new rent to nearby listings, not just apply a percentage; a tenant judging an increase should do the same. An increase far above local comparables invites vacancy for the landlord and, in unconscionability states like New Jersey or fair-rent-commission towns in Connecticut, gives the tenant a concrete challenge route.
