Graduated Rent Review: Tenant Rights in Germany

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

What is a graduated rent?

A graduated rent specifies in the lease that the rent increases by fixed amounts at certain times. Typical are concrete monthly amounts and clear dates. Important: a graduated rent must not disguise that it is a legally inadmissible increase. The clause must be transparent and the increases predetermined.

In many cases the graduated rent clause must be clearly legible and quantified in the lease.

Legal review

First check the contractual wording and compare it with the statutory rules in the BGB.[1] Pay attention to time intervals, amount specifications and whether capping or references to indices/consumer agreements exist. Case law of the Federal Court of Justice can influence interpretation.[3] If a dispute arises, civil procedural deadlines and formal requirements of the ZPO must be observed.[2]

  • Graduated-rent clause in the lease (document): Check exact amounts and dates.
  • Wording and additional clauses (form): Look for references, indexation or linkages.
  • Impact on warm and cold rent (rent): Check whether operating costs are affected.
  • Deadlines and dates (deadline): Note start and effective dates of the increases.
Documenting all payments and correspondence significantly improves your position.

Practical: When to challenge?

You can challenge a graduated rent increase if the clause is unclear, the increase does not match agreed dates or it violates statutory duties. Start with a formal request to the landlord and set a deadline for clarification. If no agreement is reached, seek advice or file suit at the local court; jurisdiction is often with the local Amtsgericht.[4]

Help with evidence collection

Make copies of the lease, all rent payments, landlord notices and photos of the apartment condition. Note phone calls with date and time. Keep written statements that document the payment trail.

  • Copy of the lease (document): Scan the pages with the graduated rent clause.
  • Proofs of rent payments (receipt): Secure bank statements and receipts.
  • Correspondence with the landlord (form): Collect e-mails and letters.
