When is a rent increase lawful?

A rent increase must be justified under tenancy law; whether the MRG or other rules apply depends on the contract and rental category.[1] Increases are often subject to deadlines and formal requirements, such as written notices or index/reference adjustments.

Tenants are often entitled to a written explanation for rent increases.

How can tenants check who pays?

  • Documents: Collect lease, previous statements and any increase notice.
  • Check the rent: Compare the requested amount with the contract, reference or index.
  • Observe deadlines: Watch for objection or approval deadlines and dates.
  • Legal steps: If unclear, court clarification at the district court may be necessary.
Detailed documentation improves your chances in disputes.

What to do with unclear or incorrect demands?

If the increase seems unclear or incorrect, act methodically: check documents, meet deadlines and request clarification in writing. Before paying, ask for a transparent calculation or contractual basis.

  • Secure evidence: Keep photos, emails, payment receipts and the increase notice.
  • Object in writing: Send a short objection with reasons and date.
  • Meet deadlines: Only timely objections are considered.
  • Legal clarification: If needed, file a claim at the district court.[2]
Respond to landlord requests within set deadlines to avoid losing rights.
