Maine Lease Extension Addendum

This Lease Extension Addendum is built with Maine as the governing state. These are the Maine landlord-tenant rules that most often bear on it, with the statute for each.

Rent, fees & rent increases

Maine regulates late fees, application fees, recurring fees, and rent-increase notices more tightly than most states — and several of these rules were added in 2023.

  • Late fees — Rent is “late” only if unpaid 15 days after it’s due. The penalty can’t exceed 4% of one month’s rent, and it can only be charged if the tenant was told in writing at signing that a late fee of up to 4% may apply (§6028).
  • Rent-increase notice — Rent or mandatory recurring fees can be raised only after at least 45 days’ written notice. If an increase — or several within 12 months — adds up to 10% or more, 75 days’ notice is required. These notice rights can’t be waived (§6015).
  • No increase while unfit — Rent can’t be raised while the unit violates the warranty of habitability, unless the tenant caused the problem (§6016).
  • Application fees — A landlord may not charge an application fee, except the actual cost of one background check, credit check, or other screening — and only after telling the applicant they’ll receive a complete copy of the results. Only one such fee is allowed per 12 months (§6030-H).
  • Recurring fees — Optional recurring fees (e.g. parking or storage) require written notice that the tenant can opt out at any time without penalty (§6030-I).
  • Rent control — Maine has no statewide rent control, but Portland runs its own rent-stabilization ordinance for covered units.
