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 Washington State, landlords are allowed to charge pet deposits, pet fees, and pet rent, but these are subject to certain regulations. According to RCW 59.18.285, a landlord may charge a pet deposit separate from the security deposit to cover damages caused by a pet. This pet deposit is potentially refundable, provided that the tenant's pet does not cause damages beyond normal wear and tear. Pet fees in Washington are typically nonrefundable and are paid to the landlord for allowing the pet to reside in the rental unit. Pet rent is an additional monthly charge that tenants pay for their pets. The amount of pet rent can vary based on factors such as the type and number of pets. It's important to note that service animals are not considered pets under the law, and landlords cannot charge pet deposits, fees, or rent for service animals. Additionally, local ordinances may impose further restrictions or requirements regarding pet-related charges, so tenants and landlords should also consult local laws in their specific city or county.
