Answer
In Uruguay, landlords are legally required to allow pets, but in practice some owners still refuse tenants with pets; pet-friendly options are scarcer. It is therefore possible to find accommodation with a pet, but it is better to agree on the terms before making a booking or signing a lease.
The landlord may request a pet deposit but is not obliged to do so and cannot impose the payment as a separate, unconditional requirement. If there is a deposit, its amount, grounds for withholding it, and refund terms should be specified separately.
The main thing for the tenant is not to hide the pet. Permission to keep the pet, additional fees, cleaning rules, use of the elevator and courtyard, and building restrictions must be set out in writing. Then a dispute will not boil down to differing recollections of a conversation with the landlord or real estate agent.
