Tenant Errors on Odor Nuisance in Germany

Dispute Resolution & Rent Reduction 2 min read · published September 07, 2025

As a tenant in Germany, odor nuisance can be a serious housing problem. Many affected people make mistakes in responding: they do not report defects in writing, do not collect evidence or react too late to the landlord's offers. This text explains concretely which formal steps are necessary, when a rent reduction may be legally possible and how to prepare documents for a possible procedure at the local court[2]. I explain terms from the BGB[1] in plain language, which deadlines are important and how to document communication and damage. The aim is to avoid common mistakes and to enforce your rights factually and securely. I list necessary evidence, explain reasonable percentage values for rent reduction depending on severity and provide practical wording help for letters to the landlord.

What is odor nuisance?

Odor nuisance occurs when unpleasant smells significantly restrict the use of the rented apartment. Legally, this can be a defect that justifies a rent reduction if the defect is not insignificant. The extent, duration and cause are decisive, as well as whether the landlord can or must ensure remedy.

Common mistakes by tenants

  • Reporting defects only orally instead of in writing with a deadline.
  • Lack of evidence: missing photos, date entries or a logbook.
  • Taking quick self-help measures without prior notice or agreement.
  • Unclear communication: not keeping copies of messages.
  • Missing deadlines, for example for defect notification or response to landlord offers.
Detailed documentation increases your chances of success.

Practical advice for securing evidence

Document odor intensity, time and duration with photos, notes and witnesses if possible. Send defect notifications by e‑mail and by registered mail or proof of delivery and state clear deadlines for remedy. Keep all landlord replies as well as tradespeople appointments and invoices. A factual tone helps to avoid escalations.

FAQ

Can I reduce the rent if odors affect the apartment?
Yes, for significant and lasting impairments a rent reduction may be possible; the amount depends on the degree and duration of the impairment.
Do I have to set a deadline for the landlord to remedy the defect first?
In most cases you should set a reasonable deadline for remedy in writing before taking reduction measures yourself or initiating legal steps.
Where can I turn if the landlord does not respond?
If the landlord does not respond, you can file a lawsuit at the competent local court or seek legal advice; in many cases prior legal advice helps.

How-To

  1. Document: Take photo, record date and time, and keep a short logbook.
  2. Report in writing: Send defect notification to the landlord and set a deadline.
  3. Wait for remedy: Record responses and appointments.
