Smoke detectors in rented accommodation: we tell you everything!

Fire safety is a priority in every home, and in Belgium, the installation of smoke detectors is a legal requirement. These devices quickly detect a fire, reducing the risk of injury and property damage. However, some homes still lack detectors or are equipped with faulty devices, raising questions of liability in the event of a fire.
Tenant's liability in case of fire
In Belgium, the tenant is presumed liable in the event of a fire, unless they prove that it was caused by an external factor (building defect, force majeure, fault of a third party, etc.). They can also demonstrate, using specific and consistent circumstantial evidence, that the fire is not attributable to them.
If he fails to overturn the presumption of liability against him, the tenant will have to bear the consequences of the fire.
This presumption is, however, supplementary, meaning that the parties can reduce or extend this liability in their lease.
Requirements regarding smoke detectors
Landlords are required to install working smoke detectors in rented properties (from one to several detectors depending on the property). They are responsible for the costs of purchasing, installing, and replacing the detectors .
Tenants , for their part, must maintain the detectors , replace the batteries and report any malfunctions to the landlord.
Consequences in the event of a disaster
The absence or lack of maintenance of detectors can have serious consequences for the parties involved.
The owner and/or tenant could be held liable for damages caused if their failure to comply with their respective obligations (lack of detector or lack of maintenance) is established as having contributed to the loss or aggravated its consequences.
Similarly, a tenant who is responsible for a fire could potentially argue that the absence of smoke detectors could contest the extent of their liability . Indeed, they could legitimately claim that, without detectors, they could not have been alerted in time to intervene or limit the damage. In such a case, a court could decide on a division of responsibility between the tenant and the landlord.
The role of insurance
Insurance plays a crucial role in the event of a fire. In Wallonia (since 2018) and Flanders (since 2019), tenants must take out fire insurance (this obligation also applies to landlords in Flanders). In Brussels, fire (and water damage) insurance has also been mandatory since November 1, 2024.
In the event of a claim, the landlord's insurer compensates the landlord for the damage to the building, then generally seeks recourse from the tenant (or their insurer, if they have one), unless there is a waiver of recourse clause . However, the absence or malfunction of detectors may lead the insurer to limit or refuse compensation.
Conclusion
Smoke detectors are essential for protecting occupants and limiting damage in the event of a fire. Landlords and tenants each have a role to play in fulfilling their legal obligations and avoiding serious legal or financial consequences. Check that your property is compliant: it's a matter of safety for everyone .
