Carbon monoxide (CO), or koolmonoxide
in Dutch, is an odorless, colorless gas produced by the incomplete combustion of fuels like natural gas, wood, or propane. In the context of a Dutch rental home, the most common potential sources are older gas-powered water heaters (geisers
), central heating boilers (CV-ketels
), and occasionally gas stoves or fireplaces. Unlike the absolute legal clarity surrounding smoke alarms, the rules for CO detectors occupy a frustratingly grey area. There is currently no national law that makes CO detectors universally mandatory in every home in the same way the rookmelderplicht
does for smoke alarms. This critical distinction is often lost on tenants and landlords alike, leading to a dangerous mix of assumption and inaction.
The lack of a hard mandate does not, however, mean the risk is any less real. Hundreds of people are hospitalized due to CO poisoning in the Netherlands each year. The danger is particularly acute in older buildings, which may still have 'open' combustion appliances that draw air from the room they are in. A poorly maintained or improperly ventilated geiser
, often tucked away in a kitchen or bathroom, can quickly and silently fill a small space with lethal gas. Tenants, especially those unfamiliar with Dutch housing stock, may not even recognize these appliances or understand the risk they pose, making the landlord's role in ensuring safety absolutely paramount.
Even without a specific law mandating a detector, landlords are bound by a broader legal principle: the zorgplicht
, or duty of care. This overarching obligation requires a landlord to provide a dwelling that is safe and free from defects that could harm the tenant. Arguably, failing to ensure the safety of a fuel-burning appliance falls squarely under this duty. This includes ensuring the appliance undergoes regular, certified maintenance (onderhoud
) and is properly ventilated. In a home containing such an appliance, a strong case can be made that the zorgplicht
implicitly requires the installation of a CO detector as a final, essential safety net. Should an accident occur, a landlord who knew (or should have known) about the risk but failed to provide a detector could be found negligent and held liable for the damages.
However, this is where the skeptical tenant must be vigilant. A landlord might interpret their duty narrowly, focusing only on the legally required biennial maintenance of the CV-ketel
while ignoring the need for a detector. They may view the device as an optional expense rather than an essential piece of safety equipment. They might perform maintenance themselves instead of hiring a certified professional (gecertificeerd monteur
), a dangerous and illegal practice. The tenant, therefore, cannot be passive. It is crucial to proactively inquire about the maintenance history of all gas appliances and to insist on the installation of a CO detector if one is not present.
Upon moving in, a tenant should immediately identify all combustion appliances. If you see an older geiser
or a CV-ketel
located inside your living space, your antennae should go up. Ask the landlord directly: "When was this appliance last serviced by a certified professional, and can you provide the maintenance report?" and "Is there a carbon monoxide detector installed?" If there is no detector, you should formally request one in writing, citing the landlord's zorgplicht
and the potential danger. A reasonable landlord will comply.
If the landlord refuses or endlessly delays, do not wait. The risk is too high. A reliable CO detector can be purchased for between €20 and €50 from any major hardware store (bouwmarkt
). This is a small price to pay for your safety. Unlike smoke alarms that go on the ceiling, CO detectors should be placed at 'breathing height' on a wall—roughly 1.5 meters from the floor—in the same room as the potential source. It should also be placed some distance away from the appliance itself to avoid false alarms. If you have appliances in multiple rooms, each room needs a detector. Taking this step yourself provides immediate peace of mind and is an essential measure if your landlord is failing their fundamental duty of care.
