Laws for pet deposits, pet fees, and pet rent vary from state to state—and sometimes between towns and cities with city codes and ordinances that address these charges.

A pet deposit is a one-time payment designed to protect the landlord and the leased premises against damages that may be caused by a tenant’s pet. Pet deposits are usually refundable, depending on the terms of the lease agreement and any applicable state or local laws.

Pet fees are usually a one-time payment required of a tenant to allow the tenant’s pet to stay at the property. Pet fees are usually nonrefundable.

Pet rent is a recurring monthly charge for the tenant’s pet to stay at the property and will often vary depending on the size and number of pets that stay at the property.

Laws regarding pet deposits, pet fees, and pet rent are usually located in a state’s statutes—and sometimes towns and cities have additional laws (city codes and ordinances) that govern a landlord’s ability to require additional charges for tenants with pets.

In Massachusetts, landlords have the right to charge a pet deposit, pet fee, or pet rent, but these charges are subject to certain regulations. The state law does not specifically regulate pet deposits, fees, or rent, but it does limit the total amount of security deposit a landlord can charge to no more than one month's rent. This means that if a landlord chooses to charge a pet deposit, it must be included within this limit. Pet fees in Massachusetts are typically nonrefundable and are considered an additional cost for allowing a pet in the rental property. Pet rent is an additional monthly charge that can be imposed for having a pet on the premises. It's important for tenants to review their lease agreements to understand the terms regarding pet-related charges. Additionally, local ordinances may have specific rules about pet charges, so it's advisable for both landlords and tenants to check for any city or town-specific regulations. An attorney can provide guidance on how these charges should be implemented in compliance with Massachusetts law and local ordinances.
