Discrimination & Equal Treatment 3 min read · published September 07, 2025

As a tenant in Germany, you may experience discrimination when accessing housing or during an ongoing tenancy. This guide helps you prepare an AGG complaint strategically: you will learn which evidence tenants should collect, which deadlines to observe and how to structure formal letters to landlords or authorities. We explain the most important legal basics in plain language, typical cases from large cities and practical action steps — from internal complaints to a possible lawsuit at the local court. The goal is to make you capable of acting, secure your rights and avoid unnecessary mistakes. This text does not replace legal advice but provides concrete, immediately applicable steps for tenants in Germany.

What is an AGG complaint?

An AGG complaint addresses discrimination under the General Equal Treatment Act (AGG). As a tenant, you can file a complaint if you were treated unfairly due to age, gender, religion, disability or origin when renting or during the tenancy[1]. The complaint can be internal to the landlord, written to the property management or serve as a basis for court proceedings. Important: documentation, witnesses and clear deadlines improve chances of success.

In Germany, the AGG also protects against certain forms of discrimination in the housing market.

Preparation and evidence collection

Before taking formal steps, tenants should systematically collect evidence and act in a structured way. The following points help to organize preparation:

  • Document evidence: photos of the apartment condition, screenshots of messages, names and contact details of witnesses.
  • Observe deadlines: note dates of incidents, set deadlines for landlord responses and save replies.
  • Prepare forms and letters: complaint letter to the landlord, if necessary a formal request by registered mail.
  • Secure correspondence: save emails, request delivery confirmations and send mail by registered post.
Detailed documentation significantly increases the credibility of your complaint.

Communication with landlord and authorities

When contacting the landlord or property management: remain factual, name deadlines and attach evidence. Request a written statement and record every conversation. If necessary, inform municipal offices or the local court about the further procedure[2].

  • Internal complaint: a short, factual letter with a request for a statement and a deadline.
  • Deadline setting: usually 14 days for a response is recommended; state a concrete deadline and send by registered mail.
  • Consider applying for legal aid (PKH) if court proceedings become necessary[3].
Keep all responses and evidence for at least two years.

Which deadlines matter?
Important deadlines include the landlord's response time (recommended 14 days), limitation periods for compensation claims and deadlines for filing a lawsuit. Check deadlines early and set clear dates.
