Rent Cap for Tenants in Germany 2025

As a tenant in Germany, it is important to know how the rent cap limits rent increases and what rights you have when the landlord raises the rent. This article explains in plain language when the cap applies, which exceptions exist and how you can formally object or request a reduction — even without a lawyer. I show which deadlines matter, which evidence helps tenants and how to use template letters and official contacts. At the end you will find practical steps for documentation, example wording for objections and notes on courts and official forms so you can enforce your rights effectively.

What is the rent cap?

The rent cap limits the percentage increase of rent within a certain period for existing tenancies. The aim is to prevent sharp rent increases in a short time and to stagger adjustments to the local comparative rent. The legal basis can be found in the German Civil Code (BGB) and supporting case law.^[1]

When does the rent cap apply?

Typical conditions for raising rent within the cap include: the increase is announced in writing, it refers to the local comparative rent and the legally specified percentage limit is not exceeded. Local or state regulations can provide exceptions.

• The rent increase must be communicated to the tenant in writing (observe form and content).
• Within the prescribed period the rent may rise by at most the statutory percentage.
• Comparative rents and evidence should be documented to verify legality.

Exceptions and special cases

New buildings, extensive modernization or agreed graduated rents have their own rules. Municipal bylaws can also set special conditions, for example in areas with tight housing markets. If in doubt, check the landlord's justification and consider court clarification if necessary.^[3]

How tenants can act without a lawyer

You can formally object, announce a reduced payment or send a written explanation with reasons to the landlord. Documentation is central: date everything, keep copies of letters, photos of defects and all receipts.

• Draft a written objection and justify it with concrete figures or missing evidence.
• Collect evidence of the local comparative rent (e.g., rent index, comparable listings).
• Observe deadlines: objections and response times are time-sensitive.

Forms and templates (official and practical)

There is no single "rent cap form" requirement, but for court actions there are standardized complaint forms and guidance from the judiciary. Use the complaint form of the competent local court if a dispute leads to eviction or litigation. Guidance on complaint types and process forms is available on official legal portals.^[2]

Courts and jurisdiction

Tenancy disputes are typically heard in the local court (Amtsgericht) in the first instance; higher-value disputes may go to the regional court (Landgericht). The Federal Court of Justice (BGH) decides on precedent-setting rental law issues.^[3]

Practical example: template for an objection

A simple objection can include: date, reference to the rent increase, concrete reasons (missing evidence, exceeding the cap), a deadline for reply and a note that you may seek clarification at the local court. Send the letter by registered mail or demonstrably by email.
