Rent Increase: Form Errors for Tenants in Germany
When is a rent increase formally incorrect?
A rent increase can be formally invalid if important information is missing or deadlines are not met. Relevant rules are found in the Civil Code (BGB).[1] Typical problems concern the justification, comparable rents and the transparency of the calculation.
- Formal error: missing or unclear justification in the increase letter.
- Missing information about the comparable rent or the calculation.
- Deadline errors: letter not properly delivered or deadlines not observed.
Detailed documentation increases your chances in disputes.
Concrete examples and which evidence helps
Example 1: The landlord cites a comparable rent but provides no comparable apartments or documentation. Example 2: The calculation contains obvious arithmetic errors. In case of doubt, the local court (Amtsgericht) is responsible.[2]
Important official forms and templates, for instance for objections or termination, can be found at the Federal Ministry of Justice.[3]
- Comparable rent claimed but without copies of the comparable apartments.
- Arithmetic mistakes or incomprehensible operating cost statements.
Collect photos, message histories and payment receipts as evidence.
How to respond? Steps for tenants
- Check the deadlines and the delivery date immediately.
- Object in writing and state your reasons.
- Provide evidence: photos, proof of payment, comparable offers.
- If necessary: consider a claim or statement at the local court.[2]
Respond in time, otherwise rights may lapse.
