Proving Construction Work for Tenants in Germany

Dispute Resolution & Rent Reduction 3 min read · published September 07, 2025

As a tenant in Germany, construction work in your building can affect your living quality, health and the usability of your apartment. This article explains practically how to collect evidence, notify the landlord correctly and when rent reduction or legal action may be appropriate. We cover documentation, deadlines, official authorities and common forms so you can enforce rights without unnecessary risks. Clear examples help decide whether to set a repair deadline first, reduce rent immediately or start legal proceedings.

When do construction works affect your tenant rights?

Construction works can be permitted, necessary or in breach of contract. The key question is whether the works significantly restrict the apartment's usability, e.g. loss of heating, weeks of noise or dust in living spaces. In such cases, you have rights under the Civil Code; specifically, Section 535 BGB covers the landlord's maintenance duties and Section 536 BGB covers defects and rent reduction[1]. Also consult procedural rules in the Code of Civil Procedure if litigation becomes necessary[2].

Documentation is often more decisive than memories or opinions.

How to collect evidence systematically

Good evidence collection strengthens your position in negotiations and in court. Collect photos, videos and written communication promptly; record date, time and duration of disturbances. Seek neutral witnesses like neighbors or caretakers.

  • Photos and videos with timestamps showing damage and noise sources.
  • Keep a disturbance log with start, end, frequency and concrete impacts.
  • Keep all letters, emails and texts with dates.
  • Note conversations with landlord or contractors (date, content, names).
The earlier you collect evidence, the more reliable it is in court.

Step: Notify the landlord and set deadlines

Notify the landlord in writing about defects, demand a deadline for remedy and state possible steps (eg rent reduction). A registered letter is not mandatory but increases evidential strength.

  • Send a written defect notice with a clear deadline and requested remedy.
  • Name a reasonable deadline (e.g. 14 days) and document when it starts.
  • Keep proof of delivery and receipt.
Phrase the notice factually and include specific demands for deadline and remedy.

Rent reduction, damages and legal action

For substantial impairments, rent reduction may be justified. The amount depends on the severity of the impairment and is often based on comparable decisions; relevant provisions are in Sections 535–580a of the German Civil Code (BGB)[1]. If remedy is not provided you can claim damages or compensation; as a last resort you can sue at the competent local court, with appeals to district courts and the Federal Court of Justice as higher instances[3].

Do not act hastily after a deadline expires without legal advice, as improper steps can be disadvantageous.

Forms and official templates

Important official items and templates include the application for a payment order (Mahnbescheid) for unpaid claims, delivery receipts for court correspondence and guidance on tenant rights on official justice sites. A Mahnbescheid is a standardized civil justice procedure that can be requested online or at the competent local court[2]. Use official guidance from state justice administrations or the Federal Ministry of Justice for correct application.
