How to use the Rent Increase Letter Generator
- Choose month-to-month or lease renewal. Renewal letters add the current lease end date and the new term.
- Enter the current rent and the increase as a new amount, a percentage or a dollar figure.
- Set the notice period your state, city and lease require, plus extra days if you will mail the letter, then pick the effective date.
- Add the landlord, tenant and property details and any reason or other changes you want to mention.
- Download or print the PDF, sign it, deliver it in a way you can prove, and keep a copy.
How the numbers in the letter are calculated
- New rent = current rent + increase. With a percentage: new rent = current rent x (1 + percent / 100). 4% on $1,650 gives $1,716.
- Percentage change = (new rent - current rent) / current rent x 100. Going from $1,650 to $1,750 is a 6.06% increase.
- Yearly impact = monthly change x 12. A $66 monthly increase costs the tenant $792 more per year.
- Earliest effective date = date of the letter + notice days + mailing days. A letter dated March 3 with 60 days' notice can take effect May 2, so the first full month at the new rent would begin June 1.
Rent increase notice rules in some states (as of 2025)
These examples show how much the rules vary. They are a starting point, not legal advice: cities can add rent control or longer notice, subsidized housing has its own rules, and laws change, so confirm the current requirement for your property.
| State | Notice for a month-to-month increase | Statewide cap |
|---|---|---|
| California | 30 days if the increase is 10% or less in 12 months; 90 days if more than 10% | 5% + local inflation, max 10% a year, for many units over 15 years old |
| Oregon | 90 days; no increase in the first year of a tenancy | Yearly cap set by the state (7% + inflation, max 10%) for buildings over 15 years old |
| Washington | 90 days | Statewide cap enacted in 2025 (7% + inflation, max 10%), with exemptions |
| New York | 30, 60 or 90 days for increases of 5% or more, depending on length of tenancy (under 1 year, 1-2 years, 2+ years) | None statewide for unregulated units; rent-stabilized units follow board orders |
| Illinois, Texas, Florida | Typically 30 days for a month-to-month tenancy, or what the lease requires | None statewide |
Tips for a smooth rent increase
- Give more notice than the minimum. Extra time helps tenants budget and lowers move-out risk.
- Check the market. Compare similar rentals nearby and use the rent increase calculator to test different percentages.
- Explain briefly. One sentence about higher taxes, insurance or improvements is usually enough.
- Stay consistent. Apply the same approach to similar units; never raise rent in retaliation for a complaint or repair request, which most states prohibit.
- Keep records. Save a signed copy and proof of delivery with the lease.
Frequently asked questions
How much notice is required for a rent increase?
It depends on the state, sometimes the city, and the lease. Thirty days is common for month-to-month tenancies, but several states require more: California requires 90 days for increases of more than 10% in a year, New York requires 30, 60 or 90 days for increases of 5% or more depending on how long the tenant has lived there, and Oregon requires 90 days. Check the current rule where the property is located.
Can a landlord raise rent during a fixed-term lease?
Generally no, unless the lease itself allows it. A fixed-term lease locks in the rent until it ends, so increases normally take effect at renewal. That is why the lease renewal option ties the new rent to the end of the current lease.
How is the earliest effective date calculated?
The tool adds the notice period and any extra days for mailing to the date of the letter. Many landlords then start the new rent on the first day of the next rental month after that date, which the 'Use earliest 1st of month' button sets for you.
Is there a limit on how much rent can be increased?
In most of the US there is no cap for market-rate housing, but there are exceptions. California and Oregon have statewide annual caps tied to inflation for many older properties, Washington enacted a statewide cap in 2025, and many cities have rent control or stabilization rules. Subsidized housing has its own rules.
What should a rent increase letter include?
The date, the tenant names and address, the current rent, the new rent, the date the new rent starts, the notice being given, and contact details. A short reason, a statement that other terms are unchanged and a tenant acknowledgment line are optional but help avoid disputes.
How should I deliver the letter?
Use a method your state allows for notices, such as personal delivery or first-class or certified mail, and keep proof. If you mail it, some states add extra days to the notice period, which is why the tool has an 'extra days if mailed' setting.
