Smoke Detectors & Fire Safety for Tenants in Sweden

Insurance & tenant liability 2 min read · published September 11, 2025

Who is responsible for smoke detectors?

As a tenant in Sweden, it is common that fixed safety installations, such as hard-mounted smoke detectors, fall under the landlord's responsibility according to legislation and practice [1]. This means the landlord usually must ensure working alarm systems are present, while the tenant is responsible for testing and reporting faults.

In many cases the landlord is responsible for fixed smoke detectors and major measures.

Smoke detectors: installation and maintenance

The following points show common practical divisions of responsibility between landlord and tenant.

  • The landlord is responsible for installation and major repairs of fixed smoke detectors (maintenance).
  • The tenant should regularly test detectors and replace simple batteries; report faults to the landlord (file).
  • The landlord normally cannot charge the tenant extra payment for standard installation or required fire safety.
  • For serious fire safety deficiencies the landlord must remedy without delay for the tenant's safety (safety).
Replace batteries and check detectors regularly to reduce risks.

If the landlord does not act

If the landlord does not remedy a serious fire safety defect after a written request, you as a tenant can apply for review with the Rent Tribunal (Hyresnämnden) or seek help via other authorities [2]. Document defects and communications carefully before proceeding.

Documentation and clear communication increase the chances that the case is resolved quickly.

Frequently asked questions
