In 2012, the Swiss electorate voted to restrict the construction of second homes. The Federal Act on Secondary Residences (ZWG) has been in force since 1 January 2016. Since then, all municipalities are obliged to draw up an annual inventory of dwellings. In this inventory, they must indicate the number of all flats as well as the number of main residences. Municipalities with a share of more than 20 percent of second homes are generally no longer allowed to approve any new ones. However, there are exceptions: tourist flats in structured accommodation establishments or granny flats as well as second homes in protected buildings are permitted. However, there are no comparable data on second homes, as each municipality records its housing stock differently.
