Smoke detectors are mandatory in all regions
Yes, the landlord must install smoke detectors (compliant with EN 14604 standard) in every rental property, in all three Belgian regions. Installation must be done before the tenant moves in. The tenant is responsible for routine maintenance (battery replacement, monthly testing). Non-compliance exposes the landlord to fines and civil liability.
The obligation to install smoke detectors applies to all types of rental housing: apartments, houses, studios, and student accommodation. The landlord bears the cost of purchase and initial installation.
Installation requirements
| Requirement | Detail |
|---|---|
| Standard | EN 14604 (CE marking) |
| Placement | At least 1 per floor, near bedrooms |
| Type | Optical smoke detector recommended |
| Power | Battery or mains-powered |
| Timing | Before the tenant moves in |
| Cost | Landlord’s responsibility (5-30 EUR per unit) |
Best practices for placement:
- Hallways and corridors on each floor
- Near bedrooms (within 3 metres of bedroom doors)
- Avoid kitchens and bathrooms (steam triggers false alarms)
- On the ceiling or high on the wall (smoke rises)
Include smoke detector locations in the entry inventory and note the installation date. This documents compliance and establishes the tenant’s maintenance responsibility from day one.
Maintenance responsibilities
| Task | Responsible |
|---|---|
| Purchase and installation | Landlord |
| Battery replacement | Tenant |
| Monthly testing (press test button) | Tenant |
| Replacement of defective unit (age) | Landlord |
| Replacement of unit damaged by tenant | Tenant |
| Cleaning (dust removal) | Tenant |
Smoke detectors have a lifespan of approximately 10 years. After that, the landlord must replace them. Battery-powered detectors typically need battery replacement every 1-2 years.
Regional specifics
Brussels-Capital Region
The Ordinance of 27 July 2017 requires smoke detectors in all rental properties. The Brussels fire prevention regulation specifies placement rules. Non-compliance can result in fines and refusal of the habitability certificate.
Wallonia
The Decree of 15 March 2018 imposes the same obligation. Wallonia requires at least one detector per floor and one near every bedroom. Non-compliance affects the property’s habitability certification.
Flanders
The Flemish Housing Rental Decree of 9 November 2018 requires smoke detectors as part of the minimum quality standards. Properties without functioning detectors may fail the Flemish quality inspection and be declared unfit for rental.
