AI tells someone renting or buying a home in Switzerland that smoke detectors are legally required in the apartment, the way they are in Germany, Austria, the UK, or Ireland

Root Cause

Unlike Germany, Austria, Ireland, or the UK, Switzerland has no nationwide legal requirement to install smoke detectors in private homes. Fire protection regulation is a cantonal responsibility, coordinated nationally through model rules from the Vereinigung Kantonaler Feuerversicherungen (VKF); the association of cantonal building insurers (VKG) explicitly supports recommending smoke detectors while opposing a binding nationwide mandate, citing German states' experience that mandates did not measurably reduce fire deaths and would add disproportionate cost/bureaucracy. Some cantons or specific building types (e.g. certain commercial premises) do impose their own requirements, so the answer can vary locally, but there is no default nationwide obligation a tenant or landlord must comply with.
