Rent Reduction for Construction in Germany

Dispute Resolution & Rent Reduction 3 min read · published September 07, 2025
As a tenant in Germany, construction work in the building can quickly become a burden, especially when noise, dust or restricted use of the apartment reduce living quality. In such cases a rent reduction may be possible, but many affected tenants do not know which steps are necessary, which deadlines apply and which evidence is required in court. This guide explains clearly how to document defects, when and how you may reduce rent, what wording is useful in letters to the landlord and how emergency proceedings at the local court work. You will also receive guidance on official rules, important deadlines and practical templates so you can assert your rights in Germany confidently and well-founded.

What applies to construction work and rent reduction?

The legal basis is mainly the BGB: the landlord's duty and rent reduction rules are set out in §§ 535–536 BGB.[1] If the usability of your apartment is restricted, that can justify a proportional rent reduction. In urgent cases, interim relief or emergency proceedings are possible; the civil procedure rules of the ZPO apply to these measures.[2]

Sections 535–536 BGB regulate rent reduction.

Which steps should you take as a tenant?

Follow these systematic steps to assert your rights and be well prepared in case of a dispute.

  • Document the defect with photos, date and time and a short description.
  • Inform the landlord in writing and demand remediation; state a deadline (e.g. 14 days).
  • Have necessary repairs carried out by professionals if the landlord does not react, and keep invoices.
  • Calculate the rent reduction proportionally and keep precise payment records.
  • In case of escalation, consult the local court or legal advice for an emergency procedure.
Detailed documentation increases your chances in a legal dispute.

Important deadlines and forms

Many measures have tight deadlines: setting a deadline for the landlord (e.g. 14 days), and for court applications interim orders can be very short-term. There is no official standard form for a "rent reduction declaration"; typically a formal letter to the landlord with description of the defect, reduction rate and date is sufficient. For court actions, use complaint forms or guidance available at the competent local court.[3]

Respond in writing and within deadlines to avoid losing claims.

How-To

  1. Collect evidence: photos, noise logs, emails and witness statements.
  2. Write a formal defect notification to the landlord and set a reasonable deadline.
  3. Request remediation; if necessary obtain professional assessments.
  4. Calculate the reduced rent proportionally and document the calculation.
  5. Apply for emergency proceedings at the local court in case of acute unreasonableness.
