Use Mietspiegel for Tenants in Germany

Rent & Rent Control 3 min read · published September 07, 2025
Using the Mietspiegel correctly is an important step for tenants in Germany to review fair rents and act legally if necessary. This text explains how to interpret the local Mietspiegel, which evidence and photos you should collect, and which deadlines apply for objections or rent increases. I name the relevant legal bases, show typical forms and explain when you can involve the local court (Amtsgericht). The goal is that as a tenant you can enforce your rights with clear documentation and the right steps, without legal jargon. Supportive notes on deadlines, templates and authorities help to handle conflicts factually and legally.

What is the Mietspiegel and when does it help?

The Mietspiegel is a statistical overview of customary local rents and serves as a guideline for rent increases or disputes over rent level. It is usually prepared by cities or municipalities and helps when negotiating with the landlord. Use the Mietspiegel when you receive a written rent increase or to start discussions about rent fairness.

The Mietspiegel is often the basis for comparisons in rent increase cases.

Which records should tenants collect?

  • Photos of defects, heating, water and electricity meters and the apartment condition immediately after moving in.
  • Dates and written defect notifications to the landlord with delivery method and date.
  • Receipts and transfer confirmations for rent and deposit payments.
  • Correspondence, tenancy agreement and previous rent statements.
Detailed documentation increases your chances in negotiations or in court.

Forms and templates (official sources)

Important official templates you can use:

  • Termination letter template (Federal Ministry of Justice - BMJ) – use if you terminate the lease or challenge an unfair termination; example: wording for contract end and return of the apartment.[3]
  • Written defect notification template – send by registered mail with return receipt if heating or water fails; document repair deadlines.
  • Application or complaint to the local court – relevant if an amicable solution fails; the Amtsgericht is the first instance for many rental disputes.
Send important letters by registered mail or with delivery confirmation.

Legal basics briefly (for tenants)

German tenancy law is largely in the German Civil Code (BGB) §§ 535–580a, e.g., landlord repair duties and rent reduction. Procedural rules for court steps are in the Civil Procedure Code (ZPO), and local courts (Amtsgerichte) handle rental disputes.[1][2]

Typical steps for an excessive rent increase

  1. Check the landlord's letter for formal correctness and deadlines.
  2. Compare the demanded rent with the local Mietspiegel and gather evidence.
  3. Send a reasoned written objection to the landlord stating your grounds.
  4. If no agreement is reached, prepare documents for a case at the local court.
  5. Use advice from official offices or consider mediation if available.
Respond to rent increase letters within deadlines, otherwise they are often deemed accepted.

FAQ

What can I do if the rent increase is above the Mietspiegel?
Check the calculation, request a written justification from the landlord and present documents proving the customary local rent. If necessary, file an objection or contact the local court.
How do I document defects correctly?
Date-stamped photos, written defect notices to the landlord by registered mail, set deadlines and keep repair offers verifiable.
What role does the local court play?
The local court usually decides on rental disputes such as rent reduction, termination and eviction suits; it is the first judicial instance in most cases.

How-To

  1. Collect all relevant documents: tenancy agreement, rent statements, photos and payment proofs.
  2. Check deadlines (e.g., for objections or rent reduction) and note dates.
  3. Send a formal defect notice or objection to the landlord, preferably by registered mail.
  4. If no agreement is possible, submit documents to the local court or get support from an official advisory service.
  5. Use official information and templates to fill forms correctly and meet deadlines.
