Mold Removal for Tenants in Germany

As a tenant in Germany, mold infestation is a serious issue that can affect your health and quality of life. This article explains clearly and pragmatically which obligations landlords and tenants have regarding mold, how to report defects correctly, which deadlines apply and when a rent reduction may be possible. I describe which evidence is important, which official forms and addresses are relevant, and how to contact the local court if a dispute arises. The goal is to give you simple steps so you can safely document mold, enforce remediation and protect your rights without requiring legal expertise.

Who is responsible for mold?

In principle, the landlord is responsible for maintaining the rental property; this is regulated by the German Civil Code (BGB). For moisture damage or structural mold, there are obligations to remedy and prevent further damage.^[1]

Immediate steps when mold is found

• Take dated photos of the infestation.
• Inform the landlord in writing (defect notice, by mail or email).
• Set a deadline for remediation (e.g., 14 days).
• Temporary measures: ventilate, heat, small drying actions.

Documentation and evidence

• Note date, time and location.
• Take photos from multiple angles and with a scale (photos, receipts).
• Document correspondence by email or registered mail.
• Keep invoices and receipts (receipts).

Rights and deadlines

For mold, a tenant can assert rights such as remediation or rent reduction under the provisions of the BGB.^[1] If the landlord does not respond, you may initiate a lawsuit or eviction action under civil procedure rules through the local court.^[2]

Important decisions by the Federal Court of Justice (BGH) clarify individual issues in mold disputes and create precedents.^[3]

FAQ

Can I reduce the rent?

Yes, if the mold impairs the suitability of the apartment. Report the defect in writing and document the extent and consequences.

Do I have to terminate the lease immediately if there is mold?

No. Termination is usually not necessary; first set deadlines for remediation and consider rent reduction or legal action.

Who pays for an expert report?

Initially the landlord is responsible for remediation, but in disputes a court can order cost allocation.
