Unlike states where landlords can freely commingle funds, Maine treats tenant security deposits with extreme strictness. Landlords must safeguard the money in specific accounts and follow aggressive timelines for its return to avoid double damages and the loss of the right to claim for damages.
Security Deposit Limits
The Two-Month Rule
In Maine, a landlord cannot demand a security deposit that exceeds the equivalent of two months' rent (14 MRS § 6032).
- Pet & Utility Deposits: Any additional deposits for pets or utilities must fit within the 2-month total cap. You cannot charge 2 months' rent plus an additional pet deposit that pushes the total over the limit.
- Exceptions: Mobile home park tenancies have a higher cap of three months' rent.
Exemption for Owner-Occupied Buildings
The strict statutory rules regarding deposit limits and return procedures (Sections 6032, 6033, and 6034) do not apply to a rental building of 5 or fewer units where the landlord also resides in one of the units (14 MRS § 6037).
Holding the Deposit Safely
A Maine landlord cannot mix a security deposit with their personal or business operating funds.
- Separate Account: The funds must be deposited into a separate, designated bank account.
- Disclosure: Upon the tenant's request, a landlord must provide the name and address of the financial institution and the specific account number holding the deposit.
The Return Deadlines: 21 vs. 30 Days
The deadline a landlord has to return a security deposit rely on the type of tenancy:
- Written Lease: The landlord has up to 30 days to return the deposit (or the balance plus an itemized list of deductions).
- Tenancy at Will (No Lease): The landlord has only 21 days to return the deposit.
Itemized Deductions
Landlords cannot deduct for normal wear and tear (e.g., minor scuffs or faded paint). Allowable deductions include:
- Unpaid rent or utility bills.
- Damage beyond normal wear and tear.
- Cleaning costs to return the unit to the condition it was in at move-in.
Penalties and "Double Damages"
If a landlord fails to return the deposit on time or withholds it wrongfully:
- Forfeiture of Right to Withhold: A landlord who misses the 21/30 day deadline strictly forfeits the legal right to retain any portion of the deposit for damages.
- 7-Day Notice Requirement: Before a tenant can sue for double damages, they must send the landlord a written notice (via certified mail or hand delivery) demanding the return of the deposit.
- Double Damages: If the landlord does not return the deposit within 7 days of receiving that notice, a court can order the landlord to pay double the amount wrongfully withheld, plus the tenant's attorney's fees and court costs (14 MRS § 6034).
Best Practices
- Document the Move-In State: Use a detailed inspection checklist with photos.
- Calendar the Deadlines: Set a reminder for the 21/30 day mark immediately upon the tenant vacating.
- Respond to the 7-Day Letter: If you receive a demand letter, return the funds immediately to avoid the risk of double damages.
