Comparative law notes

Switzerland

Since building codes in the US are local and not state-wide regulations, the scope of these laws is quite different, which is why in certain contexts when the issue involves the expanse or scale of the regulatory content, it may make more sense to use this neologism instead of the partially equivalent concept of a building code.
