Draft Amendment to the Federal Law on Second Homes (Lex Weber)
On 3 November 2022, the Environment, Spatial planning, and Energy Committees of the National Council (ESPEC/NC) presented a preliminary draft amendment to the Federal Act on Second Homes of March 20, 2015 (SHA, RS 702) to relax the conditions for the expansion, conversion or reconstruction of buildings erected under the old law, i.e., before 11 March 2012, in municipalities with a rate of second homes that exceeds 20 percent.1
Only article 11 of the SHA is affected by this draft, without affecting other articles of the law or the ordinance.
The consultation runs until 17 February 2023.
If adopted, this revision of the SHA is good news for owners of buildings erected under the old law, in municipalities with more than 20% second homes, as they will have more freedom to modify their properties.
