Can I keep a pet in a rented flat, or do I need my landlord's permission?
You don't need permission for small animals such as hamsters or fish. For cats and dogs, your landlord's permission may be required. Ask for it in writing before getting the animal.
Small animals: You can keep small animals that live in a cage or aquarium, such as hamsters, guinea pigs, budgies or ornamental fish, without asking your landlord, as long as the number is reasonable.
A blanket ban is invalid: In 2013 the Federal Court of Justice (BGH) ruled that clauses in rental contracts banning cats and dogs without exception are invalid. If your contract has such a clause, it doesn't bind you.
Cats and dogs: Your landlord can require permission in the rental contract; in that case you need to ask before getting the animal. The landlord can only refuse for a specific reason, such as the size of the animal, the condition of the flat or disturbance to neighbours. Permission for a cat usually has to be granted. For dogs it depends on the circumstances. Landlords may refuse dogs classed as dangerous (Listenhund).
Get permission in writing: Written permission that names the animal (for example "one dog, Labrador") prevents disputes later. If the animal causes ongoing noise or smells, the landlord can withdraw permission.
Cat flaps and balcony nets: Fitting a cat flap or putting up a balcony net visible from outside can count as an alteration to the property; ask for permission for these too.
If there's a dispute: A tenants' association (Mieterverein) or your district's free tenant advice service can assess your situation.
