Tenant Rights for Heating Replacement in Germany

Modernization & Cost Allocation 3 min read · published September 07, 2025
As a tenant in Germany, a heating replacement in a protected historic building can raise many questions: Who pays the costs, must the replacement comply with the GEG, and which exemptions apply for monument protection? This text explains in practical terms which rights tenants have, how negotiations with the landlord work and which forms or deadlines are important. I show how to document defects, which sections of the BGB are relevant, when a rent increase or modernization charge is permissible and how proceedings before the local court can proceed. At the end you will find concrete action steps and notes on official forms and authorities.

What tenants need to know

A heating replacement can be considered a modernization and thus trigger rights and obligations for landlords and tenants. The key issues are the provisions of the Building Energy Act (GEG) and possible exemptions for monument protection[1]. At the same time, the general tenancy law sections of the BGB regulate maintenance obligations and possibilities for a modernization charge[2]. If you are unsure, mark deadlines in your calendar and document every contact with the landlord in writing.

In many cases, the use of the apartment remains possible during the replacement, but concrete regulations depend on the individual case.

Rights, obligations and practical steps

  • Check deadlines (deadline): Find out in writing about planned dates and deadlines and request a written announcement from the landlord.
  • Clarify costs (payment): Check whether the replacement counts as a modernization and whether a charge to the rent is planned.
  • Access and repairs (repair): Clarify which craftsmen need access and which protective measures apply to your rooms.
  • Forms and evidence (form): Request all project documents, approvals and the basis for the cost allocation in writing.
  • Collect evidence (evidence): Take photos, keep a defect log and save emails and letters.
Keep all receipts and photos in a secured folder so you can prove what happened at any time.

Consider monument protection

For listed buildings, special rules may apply: energy requirements of the GEG are sometimes adapted to preserve historic fabric[1]. The landlord must generally examine alternatives and coordinate with the monument authority. Ask for the monument-related approval and request it in writing.

For interventions on listed areas, request information about protective measures and conservation work early.

How to negotiate

Good preparation strengthens your negotiating position. Start with clear, factual communication and request the necessary documents. Name deadlines, document defects and propose practical solutions, e.g. temporary heating arrangements or phased modernization charges.

  • Request documents (document): Ask in writing for project descriptions, cost estimates, monument approvals and schedules.
  • Prepare a letter (form): Draft a short letter with your demands or objections and set a reasonable response deadline (e.g. 14 days).
  • Make contact (contact): Arrange a meeting and record the results in writing.
A documented, factual proposal for a solution can often avoid costly legal disputes.

FAQ

Who pays for the heating replacement?
In principle, the landlord can bear the costs or pass them on to tenants pro rata if it is a modernization; check the documents and calculations carefully.
Can the landlord let craftsmen into the apartment without your consent?
The landlord can request access to carry out necessary works but must announce in advance and coordinate appointments.
Which deadlines are important when announcing works?
At minimum, request a written announcement with clear dates; respond to deadlines and objections promptly.

How-To

  1. Gather all information: project description, cost estimates, monument approvals and schedules.
  2. Write to the landlord: Present your questions and objections and set a reasonable deadline for a reply (e.g. 14 days).
  3. Document works and damages: Photos, logs and witness statements are important for later claims.
  4. Consider legal action: If necessary, check legal steps and clarify at the local court whether appeal or litigation is required[3].
Respond within set deadlines: missed deadlines can limit your rights.

Key Takeaways

  • Document everything: photos, emails and logs are crucial.
  • Scrutinize any cost allocation and request proof.
  • Engage early with the landlord and monument authority to find solutions.
