Know when 'house rules' violate lease

Rent it Right

Q: As a property manager, I am under contract with an owner to advertise and show his single-family rental. I recently chose new tenants and signed the lease. Since then, the owner has sent the tenants a nonsmoking policy, specifying that if any guests smoke on the property, it will constitute a violation of the lease and can result in termination.

He is also demanding proof that their dog is current on vaccinations; a statement from their vet that the dog is current on monthly flea and tick medicine; and a copy of their renters insurance policy.
