Subletting or pets: asking your landlord for permission in writing

A flatmate during a semester abroad or a dog from the shelter: both often need landlord consent. A well-reasoned letter greatly improves your chances.

Subletting

You may not sublet without permission (§ 540 BGB). For part of the flat, however, you have a right to permission if a legitimate interest arose after signing — financial reasons, work abroad, separation (§ 553 BGB). The landlord may refuse only for good cause, e.g. overcrowding.

If permission is refused without reason, you may terminate with statutory notice (§ 540(1) sentence 2 BGB).

What goes into the request

  • Name, date of birth and occupation of the subtenant
  • Which room, from when and for how long
  • Your legitimate interest

Pets

Small animals such as hamsters, fish or budgies need no permission. Dogs and cats usually need consent. A blanket ban in the lease is invalid (Federal Court of Justice, 20 March 2013, VIII ZR 168/12) — the landlord must weigh each case.
