§§ 536a–536c BGB: Damages, Move-In Defects & Duty to Report
Published on March 12, 2026
What Comes After § 536 BGB?
§ 536 BGB is the section of the BGB (the German Civil Code) that governs Mietminderung (rent reduction) itself – but three additional sections complete the picture. They determine when the landlord must pay damages, when the tenant loses their right to a reduction, and what obligations the tenant has when a defect appears. If you rent in Germany, these three sections matter just as much as § 536 itself.
§ 536a BGB – Can I Claim Damages From My Landlord?
Paragraph 1 – When Is the Landlord Liable?
The landlord must pay damages if a defect already existed at the time of signing the contract – regardless of whether they knew about it. For defects that arise later, they are only liable if they are in default on remediation (i.e., failed to act despite a deadline).
Damages can include, for example:
- Hotel costs when the apartment is uninhabitable
- Medical costs for health damage caused by mold
- Costs for damaged furniture from water damage
Paragraph 2 – Can I Fix the Defect Myself and Bill the Landlord?
If the landlord fails to fix the defect despite a deadline, the tenant may fix the defect themselves and claim the costs from the landlord. This also applies without a deadline when immediate action is necessary (e.g., an acute pipe burst). Keep every invoice – you will need them to reclaim the costs.
§ 536b BGB – What If I Knew About the Defect When I Moved In?
This section governs an important exception: if the tenant knew about the defect at the time of signing, they lose their rights to rent reduction and damages. Specifically:
- Actual knowledge: The tenant knew about the defect at move-in and signed anyway – no right to reduction
- Grossly negligent ignorance: The defect was obviously recognizable (e.g., visible mold during viewing) – no right to reduction
- Reservation: If the tenant reserved the right to remediation at move-in, their right to reduction is preserved
Tip for expats: at the apartment handover you will usually sign an Übergabeprotokoll (handover protocol). Document all visible defects in it and explicitly note that you reserve the right to assert your claims – don't let anyone rush you through this step.
§ 536c BGB – Do I Have to Report Defects to My Landlord?
Yes. Under § 536c BGB, the tenant must notify the landlord of a defect without delay as soon as they notice it. This obligation also applies to defects that arise during the tenancy. In practice, this is the Mängelanzeige (defect notice) – a short written letter describing the problem. It should be written in German, since that is the language your landlord and, if it comes to it, a German court will work with. Our service generates the letter in proper German for you.
What Happens If You Don't Report the Defect?
- Loss of the right to reduction: For the period during which the tenant should have reported the defect but did not
- Liability for damages: The tenant must compensate the landlord for damage caused by the late report (e.g., if water damage spreads)
Summary: Your Rights and Obligations Under §§ 536a–536c BGB
- § 536a: The landlord is liable for damages – and you may self-repair in emergencies
- § 536b: Always document defects at move-in and declare a reservation
- § 536c: Report defects to the landlord immediately – otherwise you risk your rights. Create defect notice →
When in doubt, a local Mieterverein (tenant association – a membership organization that provides affordable legal advice to renters) can review your case; many larger cities have staff who speak English.
