AGG Complaint 2025: Tenant Tips Germany

Discrimination & Equal Treatment 2 min read · published September 07, 2025

What is an AGG complaint?

An AGG complaint is the report of discrimination under the General Equal Treatment Act that affects a tenancy. Tenants should know that the AGG provides protection against discrimination and that tenancy duties are also regulated in the BGB[1][2]. A complaint can be filed with the landlord, the property manager, and, if necessary, with the competent courts.

In many cases, the AGG protects against discrimination during housing searches and tenancy relationships.

When and where to report?

Report incidents promptly in writing: note date, time, participants and concrete statements or actions. In severe or repeated cases tenants should consider a formal complaint to the property manager or direct filing at the competent local court; procedural steps follow the ZPO[3].

Act quickly: deadlines can limit your legal options.

Which documents and forms do tenants need?

Collect evidence (photos, messages, witnesses) and prepare a short chronological account of the incident. Typical documents are a written complaint to the landlord, a documentation file, and if necessary a complaint to be filed with the court according to the ZPO[3]. Examples:

  • Written complaint to the landlord: brief, date, incident, requested remedy.
  • Evidence folder: photos, messages, witness statements.
  • Draft complaint (if necessary): claim, reasoning, legal references to AGG/BGB.
Document all incidents immediately and keep originals and copies safe.

Practical example: sample procedure

A tenant reports repeated discrimination by the property manager. Step 1: written complaint to the manager with a deadline. Step 2: collect evidence and witness confirmations. Step 3: if no remedy, file a complaint at the local court or seek official advice. Larger legal issues can be appealed up to the BGH[4].

Good documentation increases the chances of success in any legal dispute.

Frequently Asked Questions

What counts as discrimination under the AGG?
Discrimination occurs when a person is disadvantaged because of race, ethnic origin, gender, religion, disability, age, or sexual identity; in tenancy contexts this may include rejection of an application or unequal contract terms.
Do I have to inform the landlord in writing first?
Yes, in most cases you should first inform the landlord or management in writing and set a reasonable deadline for remedy; this strengthens your position for later legal steps.
