Mountain cantons say they want to exempt existing homes from the application of the strict new initiative on secondary residences.

In February, voters approved the text to limit second homes to no more than 20 percent of a town’s housing.

The Conference of Alpine Cantons says locals in some cases could see the value of their property drop if it can’t be resold as a vacation home.

They’ll send their demands to Bern.

That’s where a working group convened by the Federal government is examining what legal changes are needed to conform to the initiative.
