Rent Cap 2025: Protect Tenants in Germany
Many tenants in Germany are unsure how to use the rent cap when a landlord wants to raise rent. This article explains in clear, practical terms which rules apply, which deadlines to watch, and which documents you should collect. We cover the connection to the rent control rules, common reasons for rent increases, the correct procedure for a formal rent increase, and your rights if the cap is exceeded. You will also find guidance on official forms, how to file an objection, and when going to the local court makes sense. The goal is for you as a tenant to plan the next steps confidently and meet deadlines to avoid unnecessary risks.
What is the rent cap?
The rent cap limits how much rent may be increased within a given period. In many areas the rule is: within three years, rent generally may not increase by more than 20%, and in some selected areas 15%. The legal basis are the rules on rent increases in the German Civil Code (BGB), especially regarding form and limits of rent increases [1].
When can tenants invoke the rent cap?
- When the landlord announces a formal rent increase and the new rent is significantly higher than the previous one.
- When the increase is planned within three years and would exceed the cap.
- When the rent increase is not properly provided in writing or does not follow legal requirements.
- When you can provide evidence such as comparable rents, photos, or previous rental agreements showing an excessive demand.
How to explain to the landlord that the rent cap applies
Respond in writing to the rent increase, state the calculation showing why the increase exceeds the cap, and request a transparent breakdown. Cite comparable apartments or prior rental agreements as evidence and indicate that you will seek judicial clarification if necessary. If needed, refer to the statutory provisions (§§ 535–558a BGB) [1] and the procedural steps under the Code of Civil Procedure (ZPO) [2].
Forms and templates
- Termination / Objection letter (template): Use a clear dated letter; the federal forms portal provides access to official forms and templates.
- Evidence list: Create a simple list with comparable rents, photos, and copies of old rental contracts.
Practical example: You receive a rent increase by mail; you write an objection within two months, attach comparable rents and request a detailed calculation. Send the letter by registered mail or deliver in person with a receipt to document delivery. For official forms visit the federal administration portal: Federal Forms Portal.
Legal steps and jurisdiction
If the matter goes to court, local courts (Amtsgerichte) are usually competent in the first instance for tenancy disputes; appeals go to regional courts (Landgerichte). Important rulings on the interpretation of tenancy law come from the highest courts like the Federal Court of Justice (BGH) [3]. The ZPO governs procedures and deadlines for lawsuits, such as eviction suits or claims to determine that a rent increase is invalid [2].
