What tenants need to know

A window replacement in a listed building may require additional permits and special conditions [2]. The landlord is generally entitled to carry out modernizations but must observe deadlines and notification rules and respect your rights under the German Civil Code [1].

  • Check deadlines (deadline): Note dates for access, execution and objections.
  • Written communication (notice): Always request written announcements and confirm receipt.
  • Secure evidence (evidence): Photograph condition and document noise, dates and agreements.
  • Check rent law (rent): Clarify whether a rent reduction is possible and how costs are allocated.
  • Check authority contact (contact): If necessary, consult the responsible monument authority for permit details.
Detailed documentation increases your chances of success in disputes.

Landlord rights and obligations

The landlord must announce modernizations, carry out measures so that your use of the dwelling is affected as little as possible, and obtain required permits (for example monument-law approvals) [2]. In addition, obligations for maintenance and repair under the German Civil Code protect you as a tenant [1].

  • Provide permits (notice): The landlord should show proof of monument-related approvals.
  • Careful execution (repair): Measures must be professionally carried out with regard to habitability.
  • Follow safety standards (safety): Protection from hazards and unreasonable intrusions is mandatory.
Respond to legal correspondence within deadlines to protect your rights.

  5. Contact the responsible authority or advice center early if needed.
  6. If it goes to court, check jurisdiction at the Amtsgericht (court) and timely filing of claims.
