Maine Security Deposit Rules (2026)

Maine caps a residential security deposit at two months’ rent. The return deadline depends on the tenancy: a written rental agreement may specify a period up to 30 days, while a tenancy at will uses 21 days after the later of termination or surrender and acceptance of the premises.

What to preserve

  • Written lease or proof the tenancy was at will.
  • Termination date.
  • Surrender/acceptance date.
  • Security-deposit amount and receipt.
  • Written itemization and refund.
  • Move-in/move-out condition evidence.

Maine does not have one universal deadline

The correct deadline depends on whether there is a written rental agreement and what period it states. A tenancy at will follows a separate 21-day rule tied to the later of termination or surrender and acceptance.

Maine deadline depends on tenancy type. Read the written agreement before applying a date; tenancy-at-will rules use a separate 21-day framework. Educational information only.
