Step-by-Step Compliance Guide
How to legally raise rent in Maine
Review Your Lease Terms
Check your current lease agreement for any rent increase provisions. Fixed-term leases typically lock in rent until the lease ends. Month-to-month tenancies allow increases with proper notice.
Calculate Your Maximum Allowable Increase
Use the applicable rent cap formula to calculate the maximum increase allowed by law. Verify your property is covered and use current CPI data if required.
Prepare Written Notice
Draft a clear rent increase notice including: current rent, new rent, dollar and percentage increase, effective date, and your signature. Keep a copy for your records.
Deliver Notice Properly
Serve the notice at least 45 days before the effective date using a valid delivery method. Personal delivery is best; if mailing, add extra days to account for delivery time.
Document Everything
Maintain records of the notice, proof of delivery, your calculations (if applicable), and any tenant communications. Keep these records for at least 3-4 years.
Update Rent Collection
After the notice period expires, update your rent roll, accounting systems, and payment portals. Begin collecting the new rent amount on the effective date.
Tenant Protections in Maine
Rules that apply even without rent control
While Maine has rent regulations, additional tenant protections apply to all rent increases. Landlords must comply with these rules regardless of the amount of the increase.
✅ Landlords CAN
- Raise rent up to the legal cap
- Raise rent at lease renewal
- Set different rents for different units
- Increase rent for improvements
- Adjust rent annually
❌ Landlords CANNOT
- Raise rent during a fixed-term lease
- Raise rent in retaliation for complaints
- Discriminate based on protected classes
- Raise rent without proper notice
- Exceed the legal rent cap
⚠️ Anti-Retaliation Protections
Maine law prohibits landlords from raising rent in retaliation against tenants who:
- File complaints about habitability or code violations
- Exercise their legal rights under the lease
- Join or organize tenant associations
- Report the landlord to government agencies
A rent increase within a certain period after such protected activity may be presumed retaliatory, shifting the burden to the landlord to prove legitimate reasons.

Improper rent increases can lead to tenant disputes, legal challenges, and potential liability. Start with thorough tenant screening to find responsible renters.
