Tenant Termination During Modernisation in Germany

Termination by Tenant 3 min read · published September 07, 2025

As a tenant in Germany, modernisation work on the building can change your living situation and sometimes raise questions about termination, rent increases, or protection against eviction. This guide explains in plain language when modernisation can justify a landlord's termination, what tenants' rights are under index rent in 2025, and which deadlines, forms, and evidence are important. You will get practical steps for responding, tips for handling modernisation notices, and information about the competent courts and official legal sources. The goal is for you as a tenant to understand your rights in Germany, meet deadlines, and make safe decisions without unnecessary legal jargon. If you are uncertain, we also show which documents to collect and how to react in time to a possible rent increase or termination.

When can modernisation lead to termination?

Modernisation measures do not automatically entitle the landlord to ordinary termination; reasons for termination must comply with the provisions of the BGB, such as economic exploitation or personal need. When referencing statutory bases, tenants and landlords find central rules on maintenance, modernisation and termination in §§ 535–580a BGB[1]. Crucial are concrete circumstances: scope of work, duration, reasonableness and whether the modernisation alone removes the purpose of the tenancy.

Keep all notices, invoices and correspondence about the modernisation project.

Index rent 2025: What tenants should know

With index rent, adjustments follow a price index; modernisation costs are not automatically passed on in the same way. Check the lease for clauses on indexation and modernisation charges and consult before agreeing to a rent increase. In disputes, the local court (Amtsgericht) often decides; appeals can reach the Federal Court of Justice (BGH)[3].

Practical steps for tenants

  • Read the modernisation notice carefully and note dates and scope.
  • Collect evidence: photos, communications, witnesses and invoices.
  • Review the lease for index clauses and modernisation agreements.
  • Submit a written objection if the measure is unreasonable or deadlines were not met.
Detailed documentation increases your chances in a legal dispute.

Which deadlines and procedures apply?

Deadlines for terminations and responses follow the BGB; in court procedures the Code of Civil Procedure (ZPO) governs claims such as eviction suits or claims for rent reduction and damages[2]. Respond promptly to service and deadlines, otherwise rights can be lost.

  • Respond within stated deadlines in writing and with documentation.
  • File objections or your own statement with the landlord if necessary.
  • On receipt of a termination, check immediately for formal errors.

Forms and official documents

There is no nationwide official "termination form" for tenants; a termination letter must contain the required information (name, address, date, clear statement of termination and signature). For court actions such as an eviction suit, use the application and complaint procedures at the competent local court (Amtsgericht). The ZPO governs the further procedure; have deadlines and service checked.

Always respond in writing and keep copies of all documents.

FAQ

Can my landlord terminate because of modernisation?
Not automatically; termination must have a legally recognized reason and consider the tenant's reasonableness. Check the grounds under the BGB.
Does index rent affect termination rights?
Index rent regulates rent adjustment to an index but does not automatically change the requirements for termination.
