Rent & Rent Control 2 min read · published September 07, 2025

As a tenant in Germany, unexpected high charges or excessive rents can cause significant uncertainty. This text explains how to spot rent gouging, when a rent increase may be legally questionable and what steps are available to you. We clearly explain the relevant sections of the BGB, which evidence matters and how to compare rent increases or assert a rent reduction. We also provide practical examples of how to write letters, meet deadlines and which local courts are responsible. The aim is to give you concrete actions so you can assert your rights confidently and lawfully in German cities. The guidance is neutral and practical, without legal jargon. If necessary, we refer to official forms and court information.

How rent gouging is defined

Rent gouging means the rent is in an obvious disproportion to comparable apartments. Crucial are the local rent index, comparable flats and whether the demand violates good morals. Relevant rules on the rental agreement and rent increase are contained in the BGB.[1] In individual cases, decisions of the Federal Court of Justice can be decisive.[2]

In most cases, comparative values are decisive.

Check: How to identify excessive rent

  • Compare with the local rent index and similar apartments
  • Check whether rent increase letters comply with deadlines and formal requirements
  • Review operating costs and one-off charges
  • Collect photos, lease agreements, payment receipts and correspondence
Respond to letters within deadlines to avoid losing rights.

Gathering evidence & forms

Systematically collect all documents: signed rental agreements, transfer receipts for payments, photos of the apartment condition and copies of advertisements for comparable rents. Use official templates for letters, for example templates for objections or terminations from the Federal Ministry of Justice.[3] For significant differences you can consider an expert report or a qualified review by a tenant advisory service.

  • Collect the lease, handover protocol and photos
  • Secure proofs of rent payments and operating cost statements
  • Keep written records of conversations and letters to the landlord
  • If necessary: expert reports or printed rent index comparisons
Detailed documentation increases your chances in court.

Local court, procedures and deadlines

If no agreement is reached, the competent local court (Amtsgericht) is the first instance for rental disputes. Claims, payment demands and eviction proceedings follow the rules of civil procedure; a case often begins with an exchange of pleadings and evidence. Early advice and meeting deadlines are important to avoid disadvantages.
