What tenants should check
When inspecting, check systematically for tightness, visible damage and consequences such as drafts or moisture. Check:
- All window frames and door joints for cracks, breaks or brittle sealing strips.
- Gaps through which air draws or water can enter.
- Condensation, water stains or signs of mold in corners.
- Function of locking mechanisms and seal compression when closing windows and doors.
Documentation and preserving evidence
Good documentation is often decisive if you assert your rights. Create a simple file and keep:
- Photos and short videos of the defective areas.
- Date and time of discovery and a description of the defect.
- Correspondence with the landlord by email or registered mail.
- Notes on phone calls with names and times.
When is the landlord responsible?
Generally, the landlord is obliged to maintain the rental property in a condition suitable for contractual use. For defects that impair usability, the landlord has the duty to repair under tenancy law rules.[1] If deadlines are not met or danger exists, court action may be necessary; procedural rules apply in such cases.[2]
How to report the defect correctly
Write a clear defect notice stating location, type of defect, date of discovery and request a deadline for repair. A factual tone and complete documentation are more effective than emotional accusations.
- Briefly describe the defect and attach a photo.
- Set a reasonable deadline for repair (e.g. 14 days) and request confirmation.
- Send the notice by email and additionally by registered mail if necessary.
Rights if defects are not remedied
If the landlord remains inactive, tenants can in some cases reduce rent, pay for urgent repairs themselves and deduct costs, or ultimately sue for remediation. Minor defects usually do not justify rent reduction; significant impairments may lead to a reduction rate. Local court (Amtsgericht) is typically responsible for disputes.[3]
