Tenant Rights: Window Replacement 2025 Germany

As a tenant in Germany, you often face many questions when a window replacement is planned: who pays the costs, what modernization rights does the landlord have, and which deadlines apply? This guide explains in clear steps how to practically plan the 2025 window replacement, check your rights and gather necessary documents. You will learn when a modernization is lawful, which evidence matters and how to contest an eviction or unjustified cost allocation. With concrete actions, deadline guidance and official sources you can be more secure in discussions with the landlord and in possible court steps. The text also shows which official forms and court actors are relevant, for example notes on filing claims before the local court and deadlines under the Code of Civil Procedure, including practical sample letters.

When may the landlord replace windows?

The landlord may renew windows if there is a modernization or maintenance need. It is decisive whether the replacement improves the usable value of the apartment or is merely a repair. Rights and duties of the landlord as well as tenant obligations are regulated in the German Civil Code.^[1]

Important: costs, notice and deadlines

Before replacement, the landlord must usually announce, justify and, if it is a modernization, possibly inform tenants about cost allocation. Always check announcement letters in writing and note appointment dates.

• Check deadlines: clarify announcement periods and appointment dates.
• Check costs: distinguish between maintenance and modernizing measures.
• Arrange access: agree clear time windows for craftsmen.
• Create documentation: collect photos, dates and written defect reports.

How to contest a window replacement

If you consider the replacement unlawful or the costs are wrongly allocated, you can react: check rent reduction, formal errors in the announcement and, if necessary, seek interim relief. Procedures and deadlines are regulated in the Code of Civil Procedure.^[2]

• Consider rent reduction: only for impairments that are not remedied.
• Apply for interim relief: seek court protection in urgent cases.
• Send written defect notice: set deadlines and secure evidence.

Which courts and laws are responsible?

For tenancy disputes the local court is usually responsible; appeals go to the regional court, and fundamental questions are decided by the Federal Court of Justice. Relevant laws include primarily the German Civil Code (tenancy law) and the Code of Civil Procedure. For certain cost questions the operating costs regulation and heating costs regulation may also be relevant.^[3]
