Report Legionella Tests: Tenants in Germany

Safety & Emergency Protections 2 min read · published September 07, 2025

What does reporting mean?

As a tenant you can report a legionella test if you have concerns about drinking water hygiene or measurement results. Landlords are responsible for traffic safety and maintenance of pipelines under the German Civil Code (BGB)[1]. In case of dispute, the Code of Civil Procedure (ZPO) regulates court procedures[2]. Reporting initially means: inform, document and set deadlines before formal legal steps become necessary.

Practical steps for tenants

  • Inform the landlord in writing and set a deadline (deadline).
  • Contact the public health office or local authority (contact).
  • Collect measurement protocols, photos and communication as evidence (evidence).
  • Create a written defect notice or use available forms (form).
  • If there is no response: consider legal steps and, if necessary, involve the local court (court).
Keep all measurement logs and photos stored safely.

Forms and authorities

There is no single nationwide template for every legionella report, but important forms and applications are relevant: for example, the application for legal aid (Prozesskostenhilfe, PKH) for court proceedings if you cannot afford the costs[4]. A payment order can help in payment disputes; for eviction claims or rent reduction disputes the local court (Amtsgericht) is responsible, and landmark decisions can be found at the Federal Court (BGH)[3].

Respond in writing and within deadlines to protect your rights.
