If water damage occurs in your apartment in Germany, prompt action is crucial. Tenants should secure the cause, document damages and inform the landlord without delay. Note the date and time, take photos and videos of affected rooms, furniture and walls, and keep a damage log. Keep receipts for repairs or emergency measures. This guide explains clearly which deadlines apply, which forms and authorities are responsible, and how to collect evidence for a rent reduction or damages in urgent proceedings. The instructions help you enforce your rights as a tenant and avoid unnecessary costs.

What to do with an acute water damage?

Act quickly to prevent further damage and secure evidence. Priority is danger prevention, then documentation.

  • Note date and time
  • Take photos and videos
  • Shut off water supply if possible
  • Inform the landlord immediately
  • Keep a damage log with witness names
Store digital copies of the photos in the cloud and email the landlord with a timestamp.

Collecting evidence: What helps in urgent proceedings

Careful documentation increases your chances in urgent proceedings. Pay attention to dating, comparison photos and receipts for costs.

  • Save before-and-after photos
  • Note witness contacts
  • Keep invoices, receipts and estimates
  • Record a short timestamped video
  • Document emergency repairs and temporary fixes
Detailed documentation increases the likelihood of success for rent reductions and urgent proceedings.

Legal bases: the landlord's duties to maintain and remedy defects are regulated in the BGB.[1] Procedural rules for emergency applications and lawsuits are in the ZPO.[2] Tenancy disputes are heard at the local court (Amtsgericht); appeals go to the Landgericht and the Federal Court of Justice (BGH).[3]

Forms and practical steps

For urgent court steps: collect evidence, prepare a short chronological overview and ready the filing (written complaint or application for an interim injunction under the ZPO). State concrete amounts, deadlines and measures in the filing.

Submit all documents completely so the court can decide promptly.
