Building insurance is mandatory for property owners in almost all cantons, except Geneva, Valais, Ticino and Appenzell Innerrhoden. However, anyone who doesn’t take out voluntary insurance coverage in these cantons has to cover the often very high costs of natural hazard damage themselves in an emergency. Building insurance is usually taken out with the canton’s building insurance office – except in the cantons of Geneva, Valais, Ticino, Uri, Schwyz, Obwalden and Appenzell Innerrhoden, where insurance coverage is offered by private providers. Basic coverage always covers damage to the building caused by fire or natural hazards, but if necessary you can take out an additional policy to expand this coverage to include other hazards, such as water damage due to burst pipes, earthquakes, deliberate damage or building collapse.
