Algorithm Bias: Tenant Rights in Germany

Many tenants in Germany notice that decisions about housing offers, credit checks or utility bills are increasingly automated. When an algorithm makes decisions that disadvantage families or individual tenants, this is called algorithm bias. This article explains in plain language what rights tenants in Germany have, how you can recognize systematic discrimination, which official steps are possible and how a sample letter for information or complaint can be worded. The goal is to provide concrete action steps — from documentation to information requests to lawsuits at the local court — so you can assert your rights clearly and securely. Read on for sample formulations, deadlines and information on official forms.

What does algorithm bias mean for tenants?

Algorithm bias occurs when automated systems make decisions that systematically disadvantage certain groups. In the rental context, this can appear in automated credit checks, the allocation of housing offers or in individual utility calculations. Tenants are entitled to fair treatment under the German Civil Code (BGB) and may, in certain cases, request information under data protection law.^[1]

Quick steps if you suspect bias

• Collect evidence (evidence): Secure screenshots, emails, bills and timestamps.
• Request information (form): Request a data access statement and an explanation of the automated decision-making.
• Send a sample letter (form): Use a template to formally request information and correction in writing.
• Seek legal advice (contact): Talk to an advisory center or lawyer before missing deadlines.

Forms, sample letter and legal basis

Important legal bases are the BGB (tenancy law, §§ 535–580a) for contractual claims and the ZPO for court procedures. For data protection issues, you can request access under the GDPR and contact the Federal Commissioner for Data Protection.^{[1] [2]}

Sample letter: Request for information and comment

A short template can be: "I hereby request information about the personal data processed and the logic used for automated decisions. Please provide the information within one month." Include the date, a precise description of the facts and your contact details. Send it by email and by registered mail if possible.

Legal steps

If information and correction are not possible or damage has occurred, tenants can file a lawsuit at the competent local court; procedures follow the ZPO rules.^[3] Common claims include injunctive relief, information or compensation under the BGB.

FAQ
