Tenants' Rights: House Rules & Modernization in Germany

Special Housing Types 3 min read · published September 07, 2025
As a tenant in Germany, you often face questions when landlords modernize and want to change house rules. This guide explains clearly which rights and duties tenants have, how modernization notices should be legally reviewed and when quiet or usage rules become transparent and binding. I describe practical steps, which deadlines to observe, how to document evidence and which official forms or courts are competent in disputes. The aim is that you avoid conflicts with the landlord, secure your living quality and know when a rent reduction or lawsuit may be appropriate. All advice is based on German law and explained for non-lawyers.

What does the house rules regulate during modernization?

The house rules can specify use, quiet times and access rules, but they must not conflict with essential provisions of the tenancy agreement or mandatory law; relevant statutory rules on the tenancy are found in the BGB (Sections 535–580a).[1]

In most regions, tenants are entitled to basic habitability standards.

What tenants should watch for

Before a modernization, tenants should request the landlord's notice in writing, check which works are planned, which costs may be passed on and whether the house rules will change. Record dates, agreements and restrictions in writing and request detailed work schedules if necessary.

  • Check deadlines: Respond to modernization notices in time and observe statutory and contractual deadlines.
  • Check forms and letters: Request detailed modernization plans, cost allocation and information about the duration in writing.
  • Documentation: Collect photos, defect reports, delivery receipts and dates for each impairment.
  • Privacy and data protection: Landlord or contractors' entries must be announced and limited to what is necessary.
Keep all letters and photos as evidence.

When is a rent reduction possible?

A rent reduction may apply if the usability of the apartment is significantly impaired by modernization measures. Assess the reduction amount based on the impairment and inform the landlord in writing; if uncertain, the local court can decide whether a reduction is justified.[1]

Respond within stated deadlines, otherwise claims may lapse.

Frequently Asked Questions

Can the landlord change the house rules unilaterally?
No, changes that substantially affect tenants are often not possible without agreement; in disputes the competent court, e.g. the local court or higher instances, will decide.[2]
What deadlines apply to modernization notices?
The notice must be made in writing and provide sufficient information; specific deadlines and contents result from Section 555b BGB and relevant case law.[1]
Which forms and authorities help in disputes?
For termination letters and formal communications, the template from the Federal Ministry of Justice can be helpful; in legal disputes the local court is the first instance, appeals go to the regional court, and revisions to the Federal Court of Justice (BGH).[3]
