The correct answer is C, Three years. Massachusetts 254 CMR 7.00 requires brokers and salespersons engaged in apartment rentals to maintain the written fee notice for three years from the date it was provided to the prospective tenant.
The regulation also contains related record-retention provisions for rental listings, documents demonstrating apartment availability, checks, money orders, cash receipts, and qualifying escrow-account checks.
Record retention is particularly important in rental brokerage because fee disputes can arise concerning who hired the broker, how much was charged, whether the property was actually available, and whether a tenancy was created.
The 2025 rental-broker-fee reforms make these records even more consequential because only the party who hired the broker may now ordinarily be charged the fee.
