Mold Removal Duties for Tenants in Germany

Repairs & Maintenance Duties 3 min read · published September 07, 2025

As a tenant in Germany, it is important to record clear agreements on mold removal in the handover protocol when moving in and out. This guide explains in plain language which obligations landlords and tenants have, how to document defects, set deadlines and which official forms or courts are responsible in case of disputes. It contains practical steps for communicating with the landlord, tips for immediate measures against mold, and examples of wording in the protocol. The aim is to give you confidence so that disputes can be avoided or resolved quickly. Keep receipts and photos and react early to moisture damage; in severe cases local courts can help; refer to the applicable statutory provisions in the BGB.[1]

What rules cover the duty to remove mold?

In general, the provisions in §§ 535 et seq. of the BGB regulate the landlord's maintenance obligations. This concerns keeping the flat in a contractually agreed condition and remedying defects.

In most cases the landlord is responsible for structural causes of mold.

Who is liable for mold?

Responsibility depends on the cause: structural defects are often the landlord's responsibility, incorrect ventilation behavior may concern the tenant. Always check the cause before making demands.

  • Landlord: Responsible for structural defects (repair) such as leaking windows, insulation faults or burst pipes.
  • Tenant: Responsible for correct ventilation and heating; proven improper behavior by the tenant can result in shared liability.
  • Cost allocation: If mold is caused by the landlord, they usually bear the removal costs; in cases of shared fault costs may be divided.
Document causes carefully to avoid later disputes.

Documentation, deadlines and forms

Good documentation is crucial: photos, dates, measurement values and witnesses strengthen your claims. Set a clear deadline for remediation and request written confirmation.

  • Document: Take photos (photo) with dates, note affected rooms and the scope of mold.
  • Set deadlines: Specify a reasonable deadline (deadline) for remediation and name a concrete measure.
  • Forms & letters: Use a written defect notice (form) and record the handover in the handover protocol.
Keep all landlord responses and contractor invoices.

Communication with the landlord

Contact the landlord in writing and politely, describe the defect precisely and attach photos. Request a deadline for remedy and, if necessary, a professional company.

  • Send a defect notice by email or registered mail with photo attachments (form).
  • Record all phone calls (call) with date, time and content as a supplement to written communication.
  • Agree on who bears which costs in a written statement if a mutual solution is found.
Phrase clearly in the handover protocol which defects existed at move-in.

If disputes arise: courts and procedures

If escalation occurs, the local court (Amtsgericht) is responsible for tenancy disputes such as rent reductions or eviction claims.[2] Before filing a lawsuit, collect all evidence and respect deadlines.

Respond to formal requirements in time, otherwise you may lose claims.

FAQ
