CO Alarms in High-Rises: Tenant Rights in Germany

As a tenant in Germany it is important to know the rules for CO alarms in high-rises and what rights you have in case of danger. This article explains clearly when landlords must provide CO warning systems, which technical requirements and inspection duties are relevant, and how you as a tenant can report defects or enforce installation. I also describe practical steps for documentation, deadlines for landlord responses and possible legal steps before the local court. I name the official forms, the responsible courts and examples when a rent reduction or other protective measures may be possible.

Legal framework

According to the German Civil Code (BGB) the rented property must be maintained so that contractual use is possible; this includes protection against dangerous gases and may therefore include the landlord's duty to provide CO alarms or ensure safe heating and ventilation systems^[1].

Landlord obligations

Landlords must identify and eliminate hazards and arrange necessary protective measures. In high-rises, structural rules and fire protection concepts can impose additional installation requirements. Report defects in writing and set a deadline for correction.

• Send a written defect notice to the landlord and set a reasonable deadline.
• Request proper repair or installation by a qualified company when technical systems are involved.
• Check whether a rent reduction is possible if CO protection is missing and the habitability is significantly impaired.

Deadlines and court jurisdiction

If the landlord does not respond, set deadlines and, if necessary, file a lawsuit with the local court; rental disputes are usually heard first at the Amtsgericht (local court)^[2]. Document all contacts and deadlines carefully.

Practical steps for tenants

Follow these steps to enforce installation or repair of CO alarms in a high-rise and to assert your rights.

• Collect evidence: keep photos, emails, messages and logs of measurements.
• Send a form or template letter to the landlord; describe the problem, location, date and request a deadline.
• Set deadlines: typically 14 days for a response unless urgent action is required.
• If unresolved: prepare and file a claim at the competent local court.

FAQ

Who pays for CO alarms in a rental building?

Generally the landlord is responsible for providing and maintaining a safe apartment; safety installations are usually the landlord's responsibility.

Can I reduce rent if there is no CO protection?

Yes, a rent reduction may be possible if the usability is substantially impaired; the amount depends on the individual case and should be documented.

What to do in case of acute poisoning risk?

In case of acute danger call emergency number 112 immediately and leave the apartment; then document and inform the landlord in writing.
