Spotting Rent Gouging: 5 Steps for Tenants in Germany

Rent & Rent Control 3 min read · published September 07, 2025

As a tenant in Germany, unexpected extreme rent increases (rent gouging) can quickly become existentially threatening. This text explains how existing tenants spot rent gouging, which documents help, and which deadlines must be observed. You will receive a clear, practical guide in five steps: from the first check of comparable rents to collecting evidence, communicating with the landlord and—if necessary—resolving the matter in court. I avoid legal jargon and name concrete laws, forms and contact points in Germany so you can check your rights clearly and enforce them effectively. Read the steps carefully and keep all documents safe. If in doubt, early advice from the local court or an official body can help.

What is rent gouging?

Rent gouging occurs when the demanded rent noticeably exceeds the usual local comparative rent or the amount is grossly disproportionate to the performance and condition of the apartment. The exact legal assessment is made based on the provisions of the Civil Code (BGB) and relevant case law.[1]

Rent gouging is an extreme individual case of excessive rent.

Legal basis and competent authorities

Important regulations are found in the BGB (e.g. §§ 535–580a) and in civil procedure law when a lawsuit arises. In tenancy disputes, the local court (Amtsgericht) is often responsible in the first instance; higher instances are the regional court (Landgericht) and the Federal Court of Justice (BGH).[1][2]

Respond promptly to formal letters, otherwise deadlines can affect your claims.

Typical evidence that helps

  • Collect tenancy agreements, service charge statements and previous correspondence with the landlord.
  • Take photos and condition reports of the apartment to document defects or missing services.
  • Note comparable rents from listings or official rent indexes as a reference.
Detailed documentation increases the chances of successfully disputing rent gouging.

Contacts and template forms

For formal steps use template letters for tenant rights and, if necessary, termination letters. If no agreement is reached, file a lawsuit at the competent local court; complex issues may be decided by the regional court or the Federal Court of Justice.[3]

Keep copies of all letters and landlord responses.

FAQ

Which deadlines must I observe?
Deadlines depend on the procedure; respond within the deadlines stated in the letter and document receipt times.

Contact advisory services or the local court first; the regional court or Federal Court of Justice decide on legal questions.
