What to do about a rent increase?

First check whether the increase is formally correct and whether the MRG applies.[1] Pay attention to the justification, the delivery and the start date of the new rent.

Keep all relevant documents stored safely.
  • Check deadlines (deadline): Whether and until when you must object.
  • Review the written increase (form): Is the calculation and delivery documented?
  • Gather evidence (evidence): Lease, payments, photos, correspondence.
  • Seek advice (contact): Contact tenant associations or legal counseling.

If the increase remains unclear, ask the landlord in writing to explain the calculation and legal basis. Formulate a short objection and state when you expect a reply.

Respond to notices in writing and keep copies of all letters.

If the landlord raises rent unlawfully

If after checking you find the increase unlawful, lodge a written objection and request a detailed explanation. If no agreement is reached, court clarification is possible; the district court is generally responsible.[2]

  • Submit a written objection (form): State date, reason and enclose evidence.
  • Attach supporting documents (evidence): lease, payments, photos, correspondence.
  • Judicial review (court): File a claim at the district court if necessary.
