For renovation and retrofit projects in Swiss cities, selecting the governing fire code is tricky: does grandfathering apply, VKF 2015, or newer cantonal enforcement directives? A flawed fire safety concept (BSK) can delay building permits for months.
Permit Filing Date Is Legally Binding
The official submission date of the building application determines the applicable codes. When directives update during planning, transition clauses must be systematically checked.
- ✓Coordinate escape routes and fire compartments with cantonal fire authorities early.
- ✓Verify material approvals against the active VKF register database.
- ✓Explicitly document the exact norm edition and cutoff date in the concept summary.
