A new law in Finland will prohibit smoking in rental apartments and balconies starting in October, unless explicitly permitted by the landlord. This regulation applies to both new and existing rental agreements, meaning current tenants are also affected. The legislation aims to reduce exposure to secondhand smoke for residents and protect properties from fire hazards. Landlords will now have the authority to decide whether smoking is allowed on their premises, potentially including designated smoking areas. Tenants wishing to smoke will need to obtain specific permission from their landlord. This change represents a significant step towards smoke-free living in Finnish rental properties and enhancing the health and safety of residents. The law seeks to address growing concerns about the negative effects of smoking on both smokers and non-smokers.
