Free rent increase letter generator

How much notice do you need to raise rent?

For a month-to-month tenancy, the baseline in most states is 30 days' written notice before the new rent takes effect. The notice period runs from the day you serve the notice to the effective date — so if your state requires 30 days and you serve on June 1, the earliest the new rent can start is July 1 (and many landlords align increases to the first of a month anyway).

Several states require more than 30 days, and a few have rules that depend on the size of the increase or the length of the tenancy. The generator above pre-fills the common default when you select a state and warns you if your effective date is sooner than that period allows.

State notice periods at a glance (month-to-month, general defaults)

• 30 days — the default in most states.
• 45 days — Maine, Hawaii.
• 60 days — Washington, Nevada, Delaware, Vermont; Maryland (and more in some counties).
• 90 days — Oregon (plus a statewide cap and no increase in year one).
• Size-based: California requires 30 days for increases up to 10% in 12 months, but 90 days if the increase exceeds 10% — and AB 1482 caps many increases at 5% + CPI (10% max).
• Tenure-based: New York scales the requirement — 30 days under one year, 60 days for one to two years, and 90 days after two years.

These are starting points, not guarantees. Rent-controlled and rent-stabilized cities (much of California and New Jersey, New York City, parts of Maryland, and others) layer on their own caps and notice rules that can exceed the state floor. When in doubt, check your city.

What to put in a rent increase letter

• Date of the notice — the notice period counts from here.
• Tenant name(s) and property address — match the lease.
• Current rent and new rent — and the dollar/percent change, so there's no ambiguity.
• Effective date — the first day the new rent is due. Give at least the required notice.
• A statement that other lease terms are unchanged — unless you're changing them, which usually needs its own notice.
• Your signature — as landlord or authorized agent.
• Optional: a brief reason — not required, but a sentence about rising taxes/insurance or a market adjustment softens the message.

Common mistakes that make a rent increase unenforceable

Not enough notice

The most common error: setting an effective date that's sooner than your state requires. If you owe 60 days and give 30, the increase simply isn't valid until enough time has passed — the tenant can keep paying the old rent until then. The tool flags this for you.

Raising rent mid-lease

A fixed-term lease locks the rent for the term. You generally can only increase at renewal or once it goes month-to-month, unless the lease has an explicit escalation clause.

Ignoring a local cap

A perfectly-formatted notice for a 15% increase is worthless if your city caps increases at 5%. Check rent-control status before you pick the number, not after the tenant pushes back.

Verbal or texted increases

Put it in writing. A text might be fine as a courtesy heads-up, but most states require a written notice delivered by an approved method to make the increase enforceable.

A note on tone

A rent increase is a business decision, but it lands as a personal one. A clear, professional letter with a one-line reason and a reasonable effective date keeps a good tenant from feeling blindsided — and a good tenant who renews is almost always cheaper than turning the unit over. Give more notice than the minimum when you can.
