Free Maine Rent Increase Notice
Maine has no statewide rent cap on how much you can raise the rent, but state law sets a firm notice rule: under 14 M.R.S. 6015 you must give at least 45 days’ written notice before the new rent takes effect – and at least 75 days’ notice when the increase is 10% or more. The increase also cannot be retaliatory. Generate a clean notice below.
This Maine Rent Increase Notice raises the rent on a residential tenancy. Maine sets no statewide cap on the amount, but 14 M.R.S. 6015 requires at least 45 days’ written notice before the increase takes effect – and at least 75 days’ when the increase is 10% or more (including increases that add up to 10% or more within a 12-month period). A waiver of that notice is void, and the increase may not be retaliatory under 14 M.R.S. 6001(3). Our how to raise rent guide covers the timing, and the tenant screening laws by state hub helps you place reliable tenants in the first place.

Maine rent-increase rules at a glance
Maine does not cap the amount of rent, but 14 M.R.S. 6015 fixes the notice. A landlord may raise the rent on a residential estate only after at least 45 days’ written notice before the new rent takes effect – and at least 75 days’ notice when the increase is 10% or more, including increases that cumulatively reach 10% or more in a 12-month period. A waiver of the notice is against public policy and void. The increase may not be retaliatory (14 M.R.S. 6001(3)). The 45/75-day rent-increase notice is separate from the 30-day notice to end a tenancy at will under 14 M.R.S. 6002. There is no statewide rent cap, though Portland’s local ordinance caps annual increases for units in that city.
How to Serve the Maine Rent Increase Notice
Determine the required notice period
Confirm the tenancy and the lease. On a written fixed-term lease the rent is locked unless the lease has an escalation clause, and any increase applies at renewal; a tenancy at will (month-to-month) can be raised prospectively with the proper written notice under 14 M.R.S. 6015.
Calculate the increase
Calculate the increase and pick the right notice period. Under 14 M.R.S. 6015, give at least 45 days’ written notice for an increase under 10%, and at least 75 days’ written notice when the increase is 10% or more – including when separate increases add up to 10% or more within a 12-month period.
Prepare the written notice
Put the increase in writing – the current rent, the new rent, and the effective date. A written or oral waiver of the 6015 notice is void, so the notice itself must give the tenant the full 45 or 75 days before the new rent takes effect; do not try to shorten it by agreement.
Serve the notice
Make sure the timing is not retaliatory. Under 14 M.R.S. 6001(3), a rebuttable presumption of retaliation arises if you raise the rent within six months after the tenant complained in good faith about a code or health-and-safety condition, requested repairs in writing, asserted a right under 6015, or filed a fair-housing complaint. A retaliatory increase is void.
Document and follow up
Serve the notice in writing by a method you can prove and keep a signed, dated copy with proof of delivery. Maine sets no required service method for a rent-increase notice, but 6015 requires the notice to be written – a verbal notice does not satisfy it. If the rental is in Portland, also confirm the increase is within the city’s annual CPI cap.
Generate the Maine Notice
Complete the fields below to generate a Maine rent increase notice. The new rent and effective date must give the tenant the full statutory notice period. Service should comply with applicable Maine law; retain proof of service.
Set the effective date correctly
Count the full notice period from when the tenant receives the notice – at least 45 days under 14 M.R.S. 6015, or at least 75 days when the increase is 10% or more – and set the effective date after it runs. An effective date that arrives before the 45 or 75 days close makes the increase unenforceable for that period. Allow added days for receipt when you mail, and remember the notice cannot be waived.

About This Maine Notice
A Maine rent increase notice is the written notice a landlord gives to raise the rent on a residential tenancy. Maine is a market-rate state: there is no statewide rent control and no statutory cap on how much the rent can go up. What state law regulates instead is how much notice the tenant must get and why the increase is being made. The governing statute is 14 M.R.S. 6015, titled “Notice of rent or mandatory recurring fee increase,” and it sets a two-tier notice rule that a Maine landlord has to get right before the new rent can take effect.
Under the first tier, a landlord may increase the rent – or a mandatory recurring fee – charged for a residential estate only after giving the tenant at least 45 days’ written notice. Under the second tier, if the increase is 10% or more, the landlord must give at least 75 days’ written notice. The 75-day rule is not limited to a single jump: if a landlord raises the rent more than once within a 12-month period and the increases add up to a total of 10% or more, the 75-day notice applies to any increase that brings the running total to 10% or more. That aggregation rule is easy to miss – two seemingly small increases a few months apart can cross the 10% line and require the longer notice. The notice runs before the increase takes effect, so the landlord counts the 45 or 75 days from when the tenant receives the notice and sets the effective date after that period closes.
The notice cannot be bargained away. Section 6015 states that a written or oral waiver of the notice requirement is against public policy and void, so a landlord cannot have a tenant agree to a shorter notice, even in the lease. A landlord who violates the section is liable to the tenant for the return of any sums unlawfully obtained, with interest, plus reasonable attorney’s fees and costs – which makes a short or skipped notice an expensive mistake. The 75-day tier does not apply to housing that already carries affordability restrictions or is governed by a subsidy program, where separate program rules set the terms of an increase.
Even with proper notice, an increase can be unlawful because of its motive. 14 M.R.S. 6001(3) creates a rebuttable presumption of retaliation when a landlord raises the rent, terminates, or refuses to renew within six months after the tenant has asserted a right – for example, complaining in good faith to a code-enforcement or health authority about a condition affecting health or safety, requesting repairs in writing, asserting a right under section 6015, filing a fair-housing complaint, or reporting being a victim of domestic violence, sexual assault, or sexual harassment. If the presumption is not rebutted, the increase is treated as retaliatory and cannot stand. Federal and Maine fair housing law independently bar an increase aimed at a tenant because of a protected characteristic.
Two points often get tangled and should be kept separate. First, the 45/75-day rent-increase notice under section 6015 is not the same as the notice to end a tenancy. Under 14 M.R.S. 6002, either the landlord or the tenant can terminate a tenancy at will on at least 30 days’ written notice – that 30-day notice ends the tenancy; it does not authorize a rent increase, and it does not shorten the 6015 notice. Second, the “no statewide cap” rule does not mean there is never a cap. Maine permits local rent control, and Portland’s voter-enacted ordinance caps annual increases for units in that city at 100% of the change in the Consumer Price Index – about 2.2% for 2026 – with a property-tax pass-through and just-cause and relocation protections, administered by the Portland Housing Safety Office. For a Portland rental, the landlord has to satisfy both the state notice rule and the city’s allowed-increase cap. Outside a city with its own ordinance, there is no cap on the amount.
Because Maine sets no required method to serve a rent-increase notice, the practical standard is provable written delivery within the notice period. Personal delivery to the tenant, service left at the premises with a mailed copy, certified mail with a return receipt, or first-class mail all work; email or a tenant portal is fine only when the lease or tenant authorizes electronic notice and you document it. Whatever the method, the notice should state the current rent, the new rent, and the effective date, and the landlord should keep a signed, dated copy with proof of delivery. Our how to raise rent guide walks through the timing, and screening applicants with verified reports keeps tenancies stable so the increases you serve actually stick.
Put together, a clean Maine increase is simple but exact: choose the right notice from the percentage – 45 days under 10%, 75 days at 10% or more, watching the 12-month aggregation – never ask the tenant to waive it, keep no mid-term change on a written lease, stay outside the six-month retaliation bar of section 6001(3), satisfy any local cap such as Portland’s, deliver the written notice with proof, and set the effective date only after the full period runs. None of this replaces the screening you do at move-in – a tenant chosen for steady income and a clean payment history is the one most likely to absorb a lawful increase without a dispute.
Maine Statutory Requirements
- No statewide cap on the amount of a rent increase, and no statewide rent control; local rent control (e.g. Portland) is permitted.
- At least 45 days’ written notice before the new rent takes effect — 14 M.R.S. 6015(1).
- At least 75 days’ written notice when the increase is 10% or more, including separate increases that add up to 10% or more in a 12-month period — 14 M.R.S. 6015(2).
- The notice cannot be waived — a written or oral waiver is against public policy and void; a violator owes the sums unlawfully collected with interest plus fees.
- No mid-term increase on a written fixed-term lease unless the lease expressly allows it; the increase applies at renewal.
- No retaliatory increase — 14 M.R.S. 6001(3) presumes retaliation if the increase follows a protected tenant action within six months.
- No discriminatory increase based on a protected class (federal Fair Housing Act and the Maine Human Rights Act).
Service Methods Permitted
- Maine sets no required method to serve a rent-increase notice, but 14 M.R.S. 6015 requires the notice to be written — a verbal notice does not satisfy it.
- Personal delivery to the tenant, or service left at the rental premises with a mailed copy.
- Certified mail with a return receipt, or U.S. first-class mail, gives a dated paper trail; allow added days for receipt when you mail.
- Email or a tenant portal works only if the lease or tenant authorizes electronic notice and you document it; keep the send record either way.
Common Mistakes
- Giving less than 45 days’ written notice, or less than 75 days when the increase is 10% or more (14 M.R.S. 6015).
- Forgetting that separate increases adding up to 10% or more in a 12-month period trigger the 75-day notice.
- Trying to shorten the notice by agreement — a waiver of the 6015 notice is void.
- Raising the rent mid-term on a written fixed-term lease that does not allow it.
- Raising the rent right after a tenant’s habitability complaint or repair request — 14 M.R.S. 6001(3) presumes retaliation.
- Confusing the 45/75-day rent-increase notice with the 30-day notice to end a tenancy at will (14 M.R.S. 6002).
- For a Portland rental, exceeding the city’s annual CPI cap.
Best Practices
- Pick the notice period from the percentage first: 45 days under 10%, 75 days at 10% or more — and add days for mailing.
- State the current rent, the new rent, and the effective date plainly, and set the effective date after the notice period runs.
- Never ask the tenant to waive the notice — the waiver is void and exposes you to the return of sums collected.
- Keep the timing outside the six-month retaliation window, and deliver by a method you can prove.
- If the unit is in Portland, check the current year’s CPI cap before setting the new rent.
Bottom line
In Maine there is no statewide rent cap, but a lawful increase turns on notice and motive: at least 45 days’ written notice under 14 M.R.S. 6015, 75 days’ when the increase is 10% or more (including increases that cumulatively reach 10% in a 12-month period), a notice that cannot be waived, no mid-term change on a written lease, and nothing inside the six-month retaliation bar of 14 M.R.S. 6001(3). Portland adds a local CPI cap on top.
Frequently Asked Questions
How much notice is required for a Maine rent increase?
Under 14 M.R.S. 6015, a Maine landlord must give at least 45 days’ written notice before a rent increase takes effect, and at least 75 days’ written notice when the increase is 10% or more. The 75-day notice also applies when separate increases add up to 10% or more within a 12-month period. The notice must be in writing – a verbal notice does not satisfy the statute – and it cannot be waived.
Is there a cap on rent increases in Maine?
No, there is no statewide cap. Maine has no statewide rent control and no statute that limits the amount of an increase; the real limits are the 45/75-day written-notice rule under 14 M.R.S. 6015 and the retaliation bar. Local rent control is permitted, though – Portland’s ordinance caps annual increases for units in that city at the local CPI change (about 2.2% for 2026), so a Portland rental has a cap even though the state does not.
How must the notice be served?
Maine sets no required service method, but 14 M.R.S. 6015 requires the notice to be written. Use a method you can prove: personal delivery, service left at the premises with a mailed copy, certified mail with a return receipt, or first-class mail. Email or a tenant portal works only if the lease or tenant authorizes electronic notice. Keep the proof either way, and allow added days for receipt when you mail.
What happens if the tenant doesn’t pay the new rent?
If the increase was served with the proper 45 or 75 days’ written notice and is not retaliatory, the tenant either pays the new rent or, on a tenancy at will, gives at least 30 days’ written notice and moves out under 14 M.R.S. 6002. If the tenant stays and pays only the old amount after a valid increase, the shortfall is unpaid rent the landlord can address through Maine’s eviction process.
Can a rent increase be illegal in Maine?
Yes. Under 14 M.R.S. 6001(3), a rebuttable presumption of retaliation arises if the increase follows a protected tenant action within six months – such as a good-faith complaint about a code or health-and-safety condition, a written repair request, asserting a right under 6015, or filing a fair-housing complaint. If the presumption is not rebutted, the increase is retaliatory and cannot stand. An increase that gives too little notice, or that a tenant was made to ‘waive,’ is also unenforceable.
What are common mistakes that invalidate the notice?
The usual errors are giving less than 45 days’ notice (or less than 75 days when the increase is 10% or more), missing the 12-month aggregation that pushes a series of increases to the 75-day tier, asking the tenant to waive the notice (the waiver is void), raising rent mid-term on a written lease that does not allow it, timing the increase as retaliation under 6001(3), and – for Portland units – exceeding the city’s CPI cap. Any one of these can make the increase unenforceable.
Can a landlord raise rent during a fixed-term Maine lease?
Not during the fixed term. On a written fixed-term lease the rent is locked unless the lease has an escalation clause, and any increase takes effect at renewal. A tenancy at will (month-to-month) can be increased prospectively with at least 45 days’ written notice under 14 M.R.S. 6015 – or 75 days when the increase is 10% or more.
