Effective Defect Notice: Tenant Rights in Germany

Dispute Resolution & Rent Reduction 3 min read · published September 07, 2025
Many tenants in Germany face the question of how to correctly report defects in their apartment, secure evidence and enforce their rights. This guide explains step by step what an effective defect notice looks like, which details and photos matter, and how to meet deadlines. You will learn when rent reduction is possible, which wording in template letters helps and how the local court becomes involved in disputes. Practical examples show how families collect documents and track deadlines. The aim is that you, as a tenant, can act confidently, avoid conflicts and, if necessary, prepare legal steps without being overwhelmed by legal terms.

What is an effective defect notice?

An effective defect notice describes the damage precisely, states date and place, requests repair and sets a reasonable deadline. The landlord's duties derive from the tenancy agreement and the BGB[1].

Contents: How to write the defect notice

  • Date and time of discovery, address and apartment number.
  • Clear description of the defect (location, scope, possible cause).
  • Photos or videos as evidence; name files with the date.
  • Clear request for remedy and setting of a deadline (e.g. "within 14 days").
  • Note on willingness to allow access for tradespeople and preference for scheduling.
  • Provide your contact details and preferred communication channel.
Detailed photos increase evidentiary strength.

Photos and evidence preservation

Photos should show the defect from several angles, include a scale (e.g. ruler) and keep metadata like date. Keep copies of emails, handover records and witness statements.

  • Unaltered photos with date and time.
  • Store original files in two locations (e.g. cloud and external drive).
  • Keep a defect log with brief entries for each event.
Detailed documentation increases your chances in negotiations or court.

Deadlines, rent reduction and legal steps

If the landlord does not remedy the defect within the deadline, rent reduction may be possible under certain conditions; the legal basis is found in the BGB[2]. In unclear cases or disputes, the local court decides under civil procedural rules[3].

  • Set a reasonable deadline (commonly 14 days, shorter depending on the defect).
  • Rent reduction: calculate the percentage and document the start date.
  • If issues persist, a claim at the local court may be necessary.
Respond to notices within deadlines to avoid losing rights.

Forms and template texts

There is no single nationwide form for defect notices, but official institutions such as the Federal Ministry of Justice provide templates and guidance. Use templates but adapt them to your case and attach photo evidence[4].

  • Sample text: date, recipient, short defect description, deadline, request for confirmation.
  • If a repair is refused, document every communication.

Frequently Asked Questions

When is a defect notice formally sufficient?
A notice is sufficient if it describes the defect, sets a deadline and is directed to the landlord; written form is recommended.
When can I reduce the rent?
You can reduce rent if the apartment has a defect that reduces its fitness for use; the reduction rate depends on the individual case.
How does a procedure at the local court work?
The local court examines evidence, hears parties and may decide on damages or eviction; often an amicable settlement is possible.

How-To

  1. Describe the defect in writing and attach photos.
  2. Send the notice by registered mail or email with read receipt and set a deadline.
  3. Secure all responses and document deadlines, appointments and repair attempts.
  4. If no solution is possible, obtain legal advice and prepare documents for the local court.

Key Takeaways

  • Good documentation is crucial for successful claims.
  • Meeting deadlines prevents disadvantages and loss of evidence.
  • Rent reduction is possible but depends on the specific situation.
