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 Maryland, landlords have the right to charge pet deposits, pet fees, and pet rent, but these charges are subject to certain regulations. A pet deposit in Maryland is typically a refundable sum that may be required by a landlord to cover potential damages caused by a tenant's pet. The amount of the pet deposit and the conditions for its return should be clearly outlined in the lease agreement. Maryland law does not specifically limit the amount a landlord can charge for a pet deposit, but it must be reasonable and related to the anticipated damages. Pet fees in Maryland are generally nonrefundable payments that a tenant pays to have their pet reside in the rental unit. Unlike pet deposits, pet fees are not intended to cover damages and are kept by the landlord. Pet rent is an additional monthly charge that a tenant pays for their pet's occupancy, and the amount can vary. It's important for tenants to review their lease agreements for any specific terms regarding pet deposits, fees, or rent. Local ordinances may also impose additional requirements or limitations, so tenants and landlords should check for any city or county-specific regulations regarding pets in rental properties.
