In Belgium

Smoke detectors are mandatory in all dwellings in Belgium, across all three Regions. The specific rules vary by Region but the principle is universal: every dwelling must be equipped with functioning smoke detectors.

Regional requirements:

  • Brussels: at least 1 detector per floor, installed on the ceiling of hallways and staircases
  • Flanders: at least 1 detector per floor, on the ceiling near bedrooms and the staircase
  • Wallonia: at least 1 detector per floor level, centrally located

How it works

Installation. The landlord is responsible for installing smoke detectors before letting the property. Detectors must comply with the EN 14604 standard.

Maintenance. The tenant is responsible for testing the detector regularly and replacing batteries (minor maintenance).

Types. Optical (photoelectric) detectors are recommended — they are less prone to false alarms than ionisation detectors. Models with built-in 10-year lithium batteries are increasingly common.

Good to know
Absence of smoke detectors can invalidate your fire insurance coverage. In case of a fire, the insurer may refuse or reduce the claim if the property was not equipped with the mandatory detectors.

Practical example

Pierre lets a 2-storey house in Namur. He installs 3 smoke detectors: one on each floor (ground, first, second). Cost: 45 EUR total (3 x 15 EUR for EN 14604-compliant detectors with 10-year batteries). The tenant tests them monthly by pressing the test button.
