Understanding Rent Increase Notice Periods Throughout Maine

Rent increase notices in Maine are not one-size-fits-all. While Maine has statewide rules that apply to most residential rentals, several municipalities have adopted longer notice periods or additional rent control requirements. For landlords and property owners, understanding these rules is essential for compliance.

Quick takeaway: Most Maine rentals require 45 days’ notice. If the increase is 10% or more, 75 days is required. Some cities require longer.

Statewide Maine Rent Increase Notice Requirements

Under Maine law, landlords must provide written notice before increasing rent. The governing statute is Maine Revised Statutes Title 14 §6015 .

This law requires:

At least 45 days’ notice for most rent increases
At least 75 days’ notice if the increase is 10% or more within a 12-month period

Maine Rent Increase Notice Periods by Location

Location	Notice Period	Source
Statewide (Most Rentals)	45 days / 75 days (10%+)	Maine Statute §6015
Portland	90 days	Portland Rent Control & Tenant Protections
South Portland	90 days	South Portland Rental Housing Program
Bangor	60 days	Bangor Tenant Protections Ordinance
Manufactured Housing Communities	90 days	Maine Statute Title 10 §9097

Why Local Rules Matter

Local ordinances can override state minimums by requiring longer notice periods or additional disclosures. This is particularly important in Portland and South Portland, where rent control rules may also limit how often and how much rent can be increased.
