Rent Increase Laws in Maine

•Rent Control
Does Maine Have Rent Control?
Yes. Portland enacted rent control in 2020 limiting increases. No statewide rent control, but state law allows municipalities to adopt rent stabilization.
Maine does not have a statewide rent-increase cap.
•Notice Requirements
How Much Notice Must Your Landlord Give?
Maine law requires written notice before a rent increase, and the period varies — notice period depends on the size of the increase: 45 days for an increase under 10% (single or cumulative over 12 months), 75 days for an increase of 10% or more (single or cumulative over 12 months) — under Me. Rev. Stat. tit. 14 § 6015.
- 45 days — an increase under 10% (single or cumulative over 12 months)
- 75 days — an increase of 10% or more (single or cumulative over 12 months)
The notice must be in writing. A verbal mention in passing does not count. If your landlord failed to give proper written notice, you do not owe the increased amount until the notice period has fully elapsed.
•Local Ordinances
Cities in Maine With Their Own Rent Control
These cities have local rent control ordinances that may be stricter than state law. If you live in one of these cities, the local rules apply to your unit — check directly with your city's rent board.
| City | Cap | Details |
|---|---|---|
| Portland | Varies | Fair Rent Portland (voter-enacted 2020): annual CPI-based cap set by the Rent Board — about 2.2% for 2026. One increase per 12 months; 90 days' notice required. |
| South Portland | 10% | Council-enacted 2023: 10% annual cap for buildings of 16 or more commonly-owned units. Sunsets 2030. |

•Take Action
What to Do If Your Rent Increase Seems Illegal
- Check the math. If Maine has a cap, calculate whether the increase exceeds it. If there is no cap, check whether the notice period was met (the notice period that applies to your tenancy (see above) under Me. Rev. Stat. tit. 14 § 6015).
- Check the timing. Mid-lease increases are generally unenforceable unless your lease explicitly allows them. Pull your lease and read it.
- Check for retaliation. Did you file a complaint, request repairs, or join a tenant organization in the last 6 months? A rent increase right after any of those is legally suspect.
- Negotiate. Even in states without rent control, landlords prefer keeping reliable tenants. Counter with a smaller increase, a longer lease term, or a delayed effective date. Get it in writing.
- Escalate if needed. File a complaint with your local rent board or housing authority. You do not need a lawyer to do this.
•Market Data
How to Check If Your Rent Is Fair
Even if your landlord's increase is technically legal, that does not mean it reflects reality. Use these tools to check whether you're being asked to pay more than the market supports:
- HUD Fair Market Rent (FMR) data — huduser.gov. The federal government publishes annual FMR estimates by county. If your new rent is significantly above the FMR for your area, you have a negotiation data point.
- Zillow / Apartments.com — search comparable units in your building or neighborhood. Screenshot the listings — this is evidence if you negotiate.
- Local tenant organizations — many maintain rent surveys and can tell you what others in your area are paying.
When you negotiate, lead with data, not emotion. “Comparable units in this ZIP code are renting for $X, and HUD's FMR for this county is $Y” is more effective than “this increase is unfair.”

How much notice does my Maine landlord have to give before raising rent?
Maine law requires written notice before a rent increase, and the period varies — notice period depends on the size of the increase: 45 days for an increase under 10% (single or cumulative over 12 months), 75 days for an increase of 10% or more (single or cumulative over 12 months) — under Me. Rev. Stat. tit. 14 § 6015. If your landlord gave you less notice than that, the increase may not be enforceable.
Can my landlord raise my rent during a lease in Maine?
Generally, no. If you have a fixed-term lease, your landlord cannot raise rent until the lease expires — unless the lease itself contains a clause allowing mid-term increases. Month-to-month tenants can receive increases with the notice period that applies to your tenancy (see above) under Me. Rev. Stat. tit. 14 § 6015.
What can I do if my rent increase seems unfair in Maine?
If your increase exceeds the legal cap, you can file a complaint with your local rent board or housing authority. Document the increase amount, the date you received notice, and the applicable statute. You are not required to pay the illegal portion while the dispute is pending.
