As a tenant in Germany you should know what an effective defect notice looks like and which deadlines apply.

This enables rights such as rent reduction or self-remedy if the landlord does not respond. This guide explains in simple language sample forms, practical steps and which official forms you can use. It shows how to secure evidence, meet deadlines and involve the competent local court or other authorities if necessary. This helps tenants keep track of their rights and act properly in cases of repairs, heating or water damage. At the end you will find FAQs, a how-to for the correct procedure and official links to forms and courts.

What is a defect notice?

A defect notice is the formal notification of a defect to the landlord so that they fulfill their maintenance obligations.[1] It should describe the defect precisely, state the date and location and set a clear deadline for remedy.

In most cases a written notice is a prerequisite for rent reduction or self-remedy.

How do I formulate the defect notice?

Formulate it factually, precisely and completely. State the defect, since when it exists, how it affects you and the deadline you set. Attach photos, measurements or witness statements.

  • Name a concrete deadline for remedy (e.g. "14 days from receipt").
  • Describe the defect precisely and add supporting photos or logs.
  • Mention possible legal consequences such as rent reduction without making unreasonable threats.
  • Send the notice in writing with proof of delivery (e.g. registered mail or receipt confirmation).
Keep a copy of the defect notice and all receipts in a safe place.

What to do if the landlord does not respond?

If there is no remedy within the set deadline, you can react step by step: assert a rent reduction, carry out repairs yourself (self-remedy) or initiate legal proceedings. Check the prerequisites before reducing rent or commissioning work.[2] The rules of the Code of Civil Procedure are relevant for court proceedings.[3]

  • Document ongoing impairments of use and, if applicable, calculate rent reduction.
  • In case of immediate danger: commission damage limitation yourself and document costs.
  • If necessary, file a lawsuit at the competent local court or contact the legal application office.
Do not react impulsively by paying full rent without legal review if the defect is substantial.
