Step Rent & Rent Brake: Tenants in Germany

As a tenant in Germany, you often face questions about step rent, the rent brake and possible rent increases. This text explains in plain language how step-rent agreements work, what rules the rent brake sets and when you can challenge an increase. You will receive a practical checklist, advice on deadlines and evidence as well as a sample letter you can adapt. We name the competent courts and legal bases so you know when proceedings at the local court are appropriate. The aim is to give you concrete steps: how to check, document and react, without complicated technical jargon.

What is step rent and how does it differ from the rent brake?

Step rent (Staffelmiete) regulates fixed increases in the rental contract at certain intervals. The rent brake (Mietpreisbremse), by contrast, limits the first re-rental or general increases in certain areas. Not every step rent is automatically invalid, but it must not violate statutory limits.

Checklist: How to review a step rent or rent brake

• Check the wording of your lease for step-rent clauses and the date of the last rent increase.
• Check deadlines: When does the next step level start and end, and were deadlines observed?
• Compare the requested rent with the rent index or customary local comparable rents.
• Document evidence: lease, older statements, photos, ads or comparable offers.
• Use a sample letter to inform the landlord and request a formal review.
• If no agreement is possible, consider a lawsuit at the competent local court.

Forms and legal bases

Important legal bases are the German Civil Code (BGB) on tenancy (§§ 535–580a)^[1] and special provisions on the rent brake in § 556d BGB^[2]. For court steps, the rules of the Code of Civil Procedure (ZPO) apply^[3]. The local court (Amtsgericht) is the first instance for many tenancy disputes, e.g., eviction suits and rent matters^[4].

How to challenge a rent increase (including sample letter)

If you believe a step rent or rent increase is unlawful, proceed systematically: check, document, object in writing, observe deadlines and, if necessary, sue. In the letter to the landlord, briefly state the reasons, announce specific evidence and set a deadline for a response.

Example content for a sample letter (stylized form):

• Details: name, address, lease start date, date of the increase notice.
• Briefly describe why you consider the increase incorrect (e.g., violation of the rent brake, unclear step clause).
• Deadline: Request a response within 14 days and announce further steps.

When should you involve the local court?

If no clarification occurs, legal action is often necessary. The local court decides in the first instance on tenancy disputes such as rent reductions, eviction suits or restitution claims. Present all documented evidence there and cite the legal bases (BGB, ZPO).

FAQ

How quickly must I respond to a rent increase notice?

Answer: Check the notice immediately, gather evidence and respond in writing within your set deadline; typically you should respond within two weeks.

Can a previous step rent be challenged retroactively?

Answer: In some cases yes, especially if the clause is invalid; deadlines and statutes of limitation must be observed.

Who decides on the admissibility of the rent brake?

Answer: Courts assess this based on statutory provisions and regional exceptions; BGB rules are decisive.
