What Is a Rent Increase Notice?
A rent increase notice is written notification to a tenant that their rent is changing and when. To write one: check the notice period your state and city require, state the property address, the current rent, the new rent and the effective date, and say how much notice you are giving. Adding the increase as a percentage is good practice. Sign it, deliver it the way the lease requires, and keep proof. The generator above does the arithmetic and the wording.
Two numbers decide whether the notice is valid: the days of notice, and the percentage. The tool shows both as you type, because those are the figures a tenant — or a housing authority — will check first.
How Much Can You Raise the Rent?
In much of the United States there is no statutory cap on an increase at renewal or on a month-to-month tenancy, and the market sets the ceiling. That has been changing. Several states now cap annual increases, and many cities operate rent stabilization with considerably tighter limits, sometimes tied to an index published each year.
Whether a cap applies to you can depend on the state, the city, the age of the building and whether the unit has been substantially renovated. It is worth ten minutes of checking before you send anything, because an increase above a cap is generally unenforceable and can carry penalties.
Mid-lease increases.A fixed-term lease fixes the rent for its term. You can normally only change it mid-term if the lease provides for it or the tenant agrees in writing. Month-to-month tenancies are different, because each period is effectively a fresh agreement — which is exactly why several jurisdictions require longer notice for them.
How Much Notice to Give
Thirty days is the common minimum, and it is what most landlords assume. Several states require 60. A number require 60 or even 90 days once the increase passes a threshold — often 10% — which is precisely why the percentage the tool calculates is worth knowing before you choose a date.
Practical advice beyond the legal minimum: send it 60 to 90 days ahead and align it to a renewal date where you can. A tenant given time to plan tends to renew; a tenant given the bare minimum tends to price out alternatives. Turnover is usually more expensive than the increase is worth — a vacant month, cleaning, advertising and screening will often exceed a year of the extra rent.
Mistakes to Avoid
Raising rent after a complaint.The most serious error on this page. An increase that follows a repair request, a code complaint or a tenants association contact can be treated as retaliation, and several states presume it if the timing is close. If an ordinary business increase happens to fall soon after a complaint, document the reason before you send it.
Raising rent mid-lease.Unless the lease allows it, the rent is fixed for the term. Sending a notice anyway undermines your position on everything else in the agreement.
Informal delivery. A text message is not notice. Follow the lease, and keep the receipt.
Hiding the percentage.Stating only the new figure reads as evasive, and the tenant will calculate it in seconds anyway. Being straightforward about the number is both better practice and better relations.
If the Tenant Pushes Back
Most increases are accepted without much discussion, but some are not, and the response is worth thinking about before you send rather than after. A tenant who asks for a smaller increase, more time, or improvements in exchange is negotiating rather than refusing — and negotiating is usually the cheaper outcome for you.
Run the arithmetic on turnover before you hold firm. A vacant month, cleaning, advertising and screening will often exceed a full year of the extra rent you were asking for. A landlord who splits the difference to keep a reliable tenant is frequently better off than one who wins the point and then re-lets the unit.
Where a tenant tells you the increase exceeds a local cap, take it seriously and check rather than reasserting the figure. Rent stabilization rules change, they apply to more buildings than most landlords expect, and an increase above a cap is generally unenforceable — sometimes with penalties attached.

Rent Increase Letter Example
The standard version. Note that it states the increase as a percentage as well as a dollar figure — your tenant will calculate it regardless, and several states cap the percentage.

Simple Rent Increase Notice Example
No reason given and no renewal invitation. Where no reason is legally required, giving one is optional — though a short explanation tends to land better than silence.

Rent Increase FAQ
How do I write a rent increase letter?
State the property address, the current rent, the new rent, and the date it takes effect. Say how much notice the letter gives. Adding the increase as a percentage is good practice — your tenant will work it out anyway, and in some states the percentage determines whether the increase is lawful. Sign and date it, and keep a copy.
How much notice do I have to give for a rent increase?
Thirty days is the common minimum for a month-to-month tenancy, but it is far from universal. Several states require 60 days, and some require 60 or 90 once the increase passes a threshold such as 10%. Local rules can be stricter still. Check your state and city before defaulting to a month.
How much can a landlord raise the rent?
In much of the US there is no statutory cap on a fixed-term renewal or a month-to-month increase, and the market sets the ceiling. That is changing: several states now cap annual increases, and many cities have rent stabilization with much tighter limits. Whether a cap applies to you depends on your state, your city, and sometimes the age of the building.
Can a landlord raise rent during a lease?
Generally no. A fixed-term lease fixes the rent for its term, and it can only change mid-term if the lease itself provides for it or the tenant agrees in writing. For month-to-month tenancies the rent can be changed with proper notice, because each period is effectively a new agreement.
Do I have to give a reason for a rent increase?
In most places, no. A brief neutral reason — market rates, rising costs, a new lease term — tends to land better than silence, and it costs nothing. In rent-stabilized and just-cause jurisdictions the position is different, and the permitted reasons and amounts may both be prescribed.
What is a reasonable rent increase?
There is no legal definition, but in ordinary markets annual increases have typically run in the low single digits to around 5%. What matters more than the benchmark is turnover: a vacancy usually costs more in lost rent, cleaning and advertising than a modest increase gains, which is worth weighing before pushing to the market ceiling.
How should a rent increase notice be delivered?
Follow whatever the lease specifies — some require certified mail or personal delivery, and notice given another way can be invalid. Where the lease is silent, certified mail with return receipt gives you dated proof. Keep a copy of the notice and the receipt together.
Can a tenant refuse a rent increase?
A tenant cannot require you to keep the old rent, but they can decline to continue at the new one and move out instead. On a month-to-month tenancy that usually means giving their own notice before the increase takes effect. In practice most increase letters are the start of a conversation rather than the end of one.
What should a rent increase notice include?
The tenant name, the full property address including unit, the date of the letter, the current rent, the new rent, the effective date, and the notice period given. Optionally the increase as a percentage, a brief reason, and an invitation to renew. Confirm that the rest of the lease is unchanged.
Is there a limit on rent increases for month-to-month tenants?
Only where state or local law sets one. Month-to-month arrangements are the easiest to change, which is exactly why several jurisdictions regulate them more tightly and require longer notice for larger increases. Check your local rules rather than assuming month-to-month means unrestricted.
When should I send a rent increase letter?
Send it far enough ahead to cover the required notice period with room to spare, and ideally aligned to a lease renewal date. Sixty to ninety days before the effective date is comfortable for most tenancies and gives the tenant time to decide rather than react.
Can a rent increase be retaliatory?
No, and this is one of the clearest rules in landlord-tenant law. Raising rent because a tenant complained, requested repairs, contacted a housing authority or joined a tenants association is unlawful in every state, and several presume retaliation if the increase follows soon after. Document the ordinary business reason for any increase that follows a complaint.
