§§ 536a–536c BGB: Damages, Move-In Defects & Duty to Report

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 responsible for them (e.g., through poor maintenance) or are in default on remediation (i.e., failed to act despite being asked to).

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.
