Many tenants in Germany are unsure about their rights when a landlord announces building work in the building or starts without prior notice. This article explains clearly and practically what obligations landlords have, when tenants can reduce rent due to impairments and how to report defects correctly. We also show which deadlines and courts are responsible in disputes, which official forms are relevant and how to document evidence with photos. The language remains accessible so you as a tenant know which steps you can take immediately and when you need legal help. At the end you will find a short how-to, an FAQ and links to official authorities so you can quickly access templates and laws.

What counts as building work in the building?

Building work includes conversions, renovations, repairs and modernizations affecting the building. Not every activity automatically entitles you to rights such as rent reduction; the decisive factors are scope, duration and impairment of living quality.

In most cases, reporting the defect to the landlord is the first necessary step.

Rights and obligations: short explanation

The landlord must keep the rented property in an agreed condition. In case of significant impairments (e.g., persistent noise, lack of heating, heavy dust), tenants can assert rights such as rent reduction after reporting the defect. The local court (Amtsgericht) is usually responsible for tenancy disputes.[1]

Respond in writing and include deadlines to avoid losing your rights.

Practical steps for building work and defects

How to act effectively if building work disturbs your apartment:

  • Set deadlines (deadline): Request a deadline for remedying the defect and document the date.
  • Collect photos and evidence (photo): Take meaningful photos, note times and disturbances.
  • Write a defect notice (form): Send a written defect notice by registered mail or email with read receipt.
  • Document repair needs (repair): Describe which facilities are affected (heating, water, electricity).
  • Consider court action (court): If no solution, a lawsuit at the local court may be necessary.[2]
Well-documented defect notices increase the chances of success for rent reduction or court proceedings.

Rent reduction: prerequisites

For legally secure rent reduction: there must be an impairment of the contractual use, you must have reported the defect to the landlord, and the reduction rate depends on the extent of the usage restriction. The legal basis is the BGB, especially the provisions on the warranty of use.[1]

Forms and authorities (official)

Important official forms and responsibilities:

  • Application for legal aid (Prozesskostenhilfe) for financial support with court costs.
  • Eviction claim and response forms: find forms and guidance at the responsible local court.
  • Application for consultation aid (Beratungshilfe) for out-of-court legal advice if you have limited means.
Keep all receipts, photos and correspondence with the landlord organized and safe.

FAQ

Can I reduce the rent if building work causes noise or dust?
Yes, under certain conditions. Report the defect in writing, document scope and duration with photos and date, and assess the reasonableness of the impairment.
Does the landlord have to announce building work?
Planned disruptive work should generally be announced. In emergencies (e.g., burst pipe) immediate action is possible; for planned modernizations, announcement periods must be observed.
Where can I turn if the landlord does not respond?
Contact the competent local court (Amtsgericht) for tenancy disputes or consider consultation aid/legal aid to obtain legal support.[3]

How-To

  1. Document the condition: photos, date, time and a clear description of the defect (photo).
  2. Send a written defect notice to the landlord and set a reasonable deadline for remedy (form).
  3. If no response: request remedy again and consider rent reduction with justification and documentation (repair).
  4. Inform the local court if necessary and prepare documents for a claim (court).
  5. Use consultation aid or apply for legal aid if costs are a barrier (support).
