Carbon monoxide and ventilation — tenant advice in Sweden
Carbon monoxide (CO) is an odorless and colorless gas that can be life-threatening at home. As a tenant in Sweden, it is important to know which measures you can take to reduce risks and how ventilation and responsibility are divided between you and the landlord. This text explains what you should do when a CO alarm sounds, how to check and document defects in ventilation or heating, what deadlines may apply and when to contact the rent tribunal or other authorities. The language is simple so you can easily follow practical steps to protect your health and your rights as a tenant. Follow the checklist below for concrete steps to take.
Risks and responsibility
Carbon monoxide forms during incomplete combustion, for example from faulty stoves, gas appliances or poor ventilation. The landlord is responsible under the Swedish Code of Land (Jordabalken) to ensure the dwelling is maintained so that basic safety and function are secured[1]. At the same time, you as a tenant have a duty to use appliances safely and immediately notify the landlord if you discover defects.
What to do if the alarm sounds?
- Leave the dwelling if several people have symptoms or if the alarm indicates high levels.
- Call 112 if anyone has severe symptoms such as unconsciousness, severe dizziness or breathing difficulties.
- Ventilate the dwelling if it is safe to do so and switch off suspected combustion sources.
Document and contact
Documentation strengthens your position if the case needs to be examined. Keep dates, photos, notes about alarm levels and any witness statements. Notify the landlord in writing and request a confirmation or action plan. If the landlord does not act you can turn to the rent tribunal for review or advice[2].
Preventive measures
Check that the stove, boiler, fans and ventilation outlets are intact and working. Ensure vents are not blocked. Request service from the landlord if you suspect faults. If ventilation is insufficient it can affect indoor air and the risk of toxic gases.
