A rent increase notice is the written notice a landlord gives a tenant before raising rent, stating the new amount and the date it takes effect. Notice periods range from 30 days in California for most increases to 90 days in Oregon and Washington and 180 days in Seattle, and fixed-term leases usually stay locked until renewal.
Legal note
This guide explains general rules as of October 1, 2026. It isn't legal advice. Rent and notice laws change often, and cities can add their own requirements on top of state law. Check your current state statute and local ordinance, or talk to a landlord-tenant attorney, before you serve a notice.
Raising the rent is one of the most routine jobs in property management, and also one of the easiest to get wrong. Hand the notice over a week late, miss a sentence your state requires, and the law may no longer recognize it, and the new rent may not start when you planned. In a few places the tenant keeps paying the old amount until a corrected notice runs its full course.
The amount of notice you owe and the language required depend on your state’s rules, how to deliver it, and the state rules worth knowing heading into 2027. That includes the new caps Oregon and Washington just published, which apply to most increases you'd be noticing right now.
When a Landlord Needs to Give a Rent Increase Notice
You need one any time you change the rent on a tenancy without a fixed end date, and any time you offer a renewal at a higher rate. How that works in practice depends on the agreement you signed.
Month-to-month tenancies
This is where notice rules matter most. Because the agreement rolls over every month, you can change the rent, but only after the written notice your state requires. In California, for instance, Civil Code §827 sets the notice period by the size of the increase over the past 12 months.
Fixed-term leases
A one-year lease generally locks the rent for the full term unless the lease itself includes an escalation clause. Most owners raise rent at renewal instead, so the notice has to reach the tenant early enough before the current term ends. If you want that flexibility written in from day one, our guide to rental agreements and lease terms explains how escalation clauses work.
Renewal offers
Some states treat a renewal at a higher rent the same way they treat a notice of rent increase. New York's Real Property Law §226-c is the clearest example: if you offer a renewal with an increase of 5% or more, you owe the tenant written notice, and how much depends on how long they've lived in the unit.
How Much Notice Is Required for a Rent Increase?
Thirty days is the most common minimum for month-to-month tenancies, sometimes through a rent-specific statute and sometimes through the general rule for changing or ending a tenancy. A growing group of states and cities now require much more. Here's where several major rental markets stand as of October 2026.
Minimum written notice before a rent increase takes effect, in jurisdictions with a notice statute. Texas and Florida have none.
Oregon and Washington: the 2027 caps are already out
Oregon's Department of Administrative Services published its 2027 cap on September 28, 2026: 10%, up from 9.5% in 2026. The 2026 figure comes from the department's own 2026 rent stabilization notice, and the formula itself sits in ORS 90.324. Washington's Department of Commerce had already set its 2027 limit at 10%, up from 9.683% this year.
Pay close attention to which year’s notice requirements apply.
Both states require 90 days' notice, so an increase you serve in October 2026 won't take effect until 2027. The cap that applies is the one for the year the new rent starts. Using this year's percentage on a January increase is an easy mistake, and in this case it would actually shortchange you, since both 2027 caps are higher.
California: two notice periods and a statewide cap
California splits the notice by size. An increase of 10% or less over the prior 12 months needs 30 days; anything above that needs 90. Most units older than 15 years also fall under AB 1482's cap, and many cities layer stricter local rent control on top. Because the rules get detailed fast, we keep the full breakdown in our California landlord tenant law guide.
New York: notice scales with tenancy length
Under RPL §226-c, the notice for an increase of 5% or more runs 30 days for a tenant who has lived there under a year, 60 days for one to two years, and 90 days for two years or longer. The notice also has to state whether the unit is covered by the state's good cause eviction law. If you're late, the tenancy simply continues on its existing terms until a proper notice period has passed.
Rent-stabilized apartments in New York City follow a separate track. The Rent Guidelines Board set 0% for both one- and two-year leases that start between October 1, 2026 and September 30, 2027.
Texas and Florida: the lease does the work
Neither state has a statute telling you how far ahead to announce a rent increase. In practice, owners on month-to-month agreements give at least as much notice as it takes to end the tenancy, because a tenant who won't accept the new rent needs time to leave. That's one month in Texas under Property Code §91.001 and 30 days before the end of a monthly period in Florida under §83.57. If your lease sets a longer period, you're bound by it.

How Much Can a Landlord Raise Rent?
In most of the country, there's no legal ceiling. The market sets the number and the law only controls notice. The picture changes in places with a cap:
• California: 5% plus regional CPI, never more than 10% in 12 months, for units covered by AB 1482.
• Oregon: 9.5% for increases taking effect in 2026 and 10% in 2027, with one increase allowed per 12 months.
• Washington: 9.683% in 2026 and 10% in 2027 for most residential tenancies.
• Local rent control or stabilization: cities such as New York set their own limits, which can be far lower than any state cap.
A quick way to sanity-check a number: divide the dollar increase by the current rent. Raising $2,000 rent by $300 is a 15% increase. That's fine in Texas with proper notice, but it's above the cap in all three capped states, and in California it would also trigger the 90-day notice rule if the unit weren't covered.
Even where there's no cap, think about what the tenant will do next. A long vacancy can cost more than the extra rent would have brought in, which is why many owners keep renewal increases close to local market rents rather than at the legal maximum.
What to Include in a Rent Increase Notice
A clear notice heads off most disputes before they start. At a minimum, include:
• The date of the notice and the tenant's full name
• The rental address, including the unit number
• The current rent and the new rent, plus the dollar and percentage change
• The exact date the new rent takes effect, ideally the first day of a rental period
• A line confirming that the rest of the agreement stays the same
• Any wording your state or city requires, such as New York's good cause eviction statement or Seattle's tenant-rights contact information
• How and when you delivered the notice, and your signature and contact details
Required wording matters more than most owners expect. Seattle, for example, says a notice that doesn't follow the state format and include the city's renter-rights language can't be enforced.
Rent Increase Notice Template and Sample Letter
Here's a sample rent increase letter you can adapt. Use this template as a starting point and adapt it to your state’s legal requirements: swap in your state's notice period and add any required statements before you use this rent increase letter template.
[Date]
[Tenant full name(s)]
[Rental property address, unit number]
NOTICE OF RENT INCREASE
Dear [Tenant name],
This letter is formal notice that the monthly rent for [property address] will increase from $[current rent] to $[new rent], a change of $[dollar amount] ([percent]%). The new rent takes effect on [effective date], which is at least [required number] days after the date this notice is delivered.
All other terms of your [rental agreement or lease] stay the same. Please pay the new amount starting with the rent due on [effective date], using [payment method].
[Insert any statement your state or city requires, for example Washington's statutory notice language, Seattle's renter-rights contact information, or New York's good cause eviction disclosure.]
If you have questions, you can reach me at [phone] or [email].
Sincerely,
[Landlord or manager name]
[Mailing address]
Delivered on [date] by [personal delivery, first-class mail, or another method your state allows].
How to Deliver a Rent Increase Notice
A notice can still be invalid if it isn’t delivered according to the required procedure. The rule of thumb: use a method your state's law names, and keep proof that you did.
• Personal delivery is accepted almost everywhere and starts the clock right away. Note the date, time and who received it.
• Mail is allowed in many states but can add days to the count. California's §827, for one, makes mailed notices subject to the state's rules for service by mail.
• Posting plus mailing is an option in some places. Seattle accepts personal delivery, or posting on the property combined with first-class mail.
• Email or a tenant portal only works if your state allows it and, ideally, your lease says so. When in doubt, send a paper copy too.
Keep a copy of the notice and your proof of delivery in the tenant's file. If anyone questions the increase later, that record is what settles it.
Common Rent Increase Mistakes That Can Cost You
Common mistakes include using the wrong notice period, leaving out required language, or failing to follow delivery rules.
• Raising rent mid-lease. Without an escalation clause, a fixed-term lease usually holds the rent until it ends.
• Counting days wrong. Count from the day the tenant actually receives the notice, and add any extra time your state requires for mail.
• Using last year's cap. In Oregon and Washington, the year the new rent starts decides which percentage applies.
• Leaving out required language. A missing statement can make an otherwise correct notice unenforceable.
• Raising rent unequally for the wrong reasons. The federal Fair Housing Act bars discrimination based on race, color, religion, sex, national origin, familial status or disability. An increase timed right after a repair complaint can also raise retaliation questions under state law.
• Forgetting the FCRA. If a tenant screening or credit report played any part in a decision to raise someone's rent, the FTC says you must give that tenant an adverse action notice. Our tenant screening guide walks through what that notice must include.
Rent increase notices are only one of the notices owners send. If a tenant falls behind after an increase, our guide on what to do when a tenant stops paying rent covers pay-or-quit notices, which follow very different rules.
Timing a Rent Increase Around Lease Renewal
The easiest way to stay compliant is to work backward from the date you want the new rent to start. Say a Washington lease ends January 31, 2027, and you want the new rent on February 1. Ninety days before February 1 is November 3, 2026, so the notice has to be in the tenant's hands by then. If you're mailing it, build in more time.
A simple habit helps: flag every lease about 120 days before it ends. That gives you a few weeks to check market rents, decide on the number and get the notice out, even in a 90-day state. It also gives tenants time to plan, which tends to make renewals smoother.
How ManageCasa helps with renewals
ManageCasa's leasing tools let owners send lease documents and addendums for eSignature, track whether each one has been signed, and store the completed copy in the tenant's record. For a rent increase, that keeps the signed renewal or rent addendum, and the date it went out, in one place if a question comes up later.
Frequently Asked Questions
Can a landlord raise rent by $300 at once?
In most states, yes, because there's no dollar limit on a rent increase, only rules about notice. Capped markets are the exception. A $300 increase on $2,000 rent is 15%, which is above the statewide caps in California, Oregon and Washington for covered units. Everywhere, the increase still needs proper written notice first.
How much notice is needed for a rent increase?
It depends on the state, but 30 days is the most common minimum for month-to-month tenancies. Oregon and Washington require 90 days, Seattle requires 180, and California and New York scale the notice to the size of the increase or the length of the tenancy. Check city rules too, since some set longer periods.
Can a landlord increase rent every year?
Yes. In most states a landlord can raise rent once a year, or even more often, as long as each increase gets the notice the law requires. Oregon allows only one increase in any 12-month period and none in the first year. Washington also bars any increase during the first 12 months of a tenancy.
How much can a landlord raise rent in NYC?
For rent-stabilized apartments with a lease starting between October 1, 2026 and September 30, 2027, the allowed increase is zero: the Rent Guidelines Board set 0% for one- and two-year renewals. Market-rate apartments have no cap, but an increase of 5% or more needs 30 to 90 days' written notice.
What happens if a landlord doesn't give proper notice of a rent increase?
Usually the increase can't take effect until proper notice is given and the full notice period has run. In New York, the tenancy continues on its existing terms until a timely notice period expires. If the notice is defective, correcting the issue early can prevent a larger dispute later, most landlords serve a corrected one and move the effective date back.
