You want to be sure every tenant signs a pet exhibit so every detail is covered. Don’t try to cover this in the lease as it stretches it out. If they have a pet you want them to tell you breed, weight, color and name so they don’t sneak in a different one. You also want to remind them of the six things they need to do after move-out to get their deposit back. If they don’t have a pet you need to remind them of the costs, penalties and process you’ll go through if you discover a pet. Let them know there are serious penalties if they get caught with an unauthorized pet.
