Proving Building Work for Tenants in Germany

Dispute Resolution & Rent Reduction 3 min read · published September 07, 2025
As a tenant in Germany, you may sometimes face building work in your block that affects your living quality. This guide explains step by step how to prove building work with photos and simple documents, assert rights such as rent reduction, and when to notify the landlord or the local court. You will receive practical tips on correct photo documentation, deadlines, sample forms, and safe storage of evidence. The text contains concrete wording examples for a written defect notice, guidance on setting deadlines, and how to inspect building plans or permits. I also describe which official forms are relevant and how to date, secure, and present photo evidence in a dispute.

What Tenants Should Know

Building work can cause temporary noise, dust, or limited use of the apartment. As a tenant, you have obligations and rights: the landlord must maintain the rented property; if there are disturbances, a rent reduction may be possible. If out-of-court resolution fails, the local court (Amtsgericht) can be used.[1]

Detailed photos with dates increase evidentiary weight.

Key Evidence Steps

  • Take photos of damage and construction (photo, evidence) from different angles.
  • Record date and time (time), e.g., with camera timestamps or a log.
  • Send a written defect notice to the landlord (form) and document receipt.
  • Check rent reduction (rent): justify percentage and record the period.
  • Name witnesses or neighbors as contacts who can confirm disturbances.

When photographing, use reference points (furniture, sockets) and take overview and detail shots. Save copies in at least two places (for example, cloud and external drive). If possible, note daily disturbance times to show a pattern.

Detailed documentation improves your chances in rent reduction claims or court proceedings.

Forms and Legal Bases

Key legal bases are anchored in the German Civil Code (BGB), notably the landlord's maintenance obligations.[1] Court actions follow the rules of the Code of Civil Procedure (ZPO).[2] Precedents from the Federal Court of Justice (BGH) may be relevant.[3]

Relevant forms and templates (practical use):

  • Defect notice (own letter): When to use: always upon disturbances. Example: a text template setting a 14-day deadline for remedy.
  • Rent reduction letter (own letter): When to use: after ongoing impairment; include a sample calculation for percentage reduction.
  • Lawsuit form / application at the local court (civil complaint): When to use: if the landlord does not respond or the matter is disputed; example: eviction or payment claim with submitted evidence.

If you send a letter to the landlord, consider registered mail or personal handover with a receipt. Set clear deadlines (e.g., 14 days) and state desired remedies.

Practical Steps Before Court

Before suing, document all attempts at out-of-court resolution: emails, letters, photos, witness statements, and time logs. Present these records orderly so the local court can quickly assess the facts.[2]

Respond to legal or court letters within deadlines to avoid losing rights.

FAQ

Can I reduce the rent because of building work?
Yes, if the usability of your apartment is significantly restricted, you may reduce the rent. Justify the amount and period with evidence such as photos and logs. Consult the relevant BGB provisions if in doubt.[1]
Do I have to tolerate construction announced by the landlord?
Partly yes: minor repairs for maintenance are permissible; major interventions must be announced adequately. Your interests must be considered; disproportionate disturbances may lead to reductions or damages.
Where can I turn if the landlord does not react?
First try written requests and deadline setting. If there is no response, you can involve the local court or seek legal advice. Court actions follow the ZPO.[2]

How-To

  1. Create photos systematically: overview, details, close-ups; include date and time for each photo.
  2. Send a written defect notice to the landlord and set a deadline (e.g., 14 days).
  3. Gather witness contacts and secure written statements.
  4. Calculate rent reduction and keep clear documentation if you withhold or deposit the amount.
  5. If no agreement is reached: prepare a lawsuit at the local court and submit ordered evidence.

Key Takeaways

  • Photo documentation with timestamps is central to proving disturbances.
  • Always send a written notice with a clear deadline before taking stronger measures.
