Question: A tenant requested that he be allowed to have an assistance animal in the rental property as a reasonable accommodation because he has a disability. The property owner normally requires a pet deposit. Can the property owner require that the tenant pay a pet deposit as a condition for allowing the assistance animal in the rental property?
No. A property owner cannot require a tenant to pay a pet deposit or any other additional deposit as a condition for allowing an assistance animal in a rental property. However, a tenant with an assistance animal will still be considered legally responsible for any damage caused by that animal.
