What changed in December 2025
The federal reform applies from 22 December 2025. It strengthens competency requirements for inventories and worker exposure prevention. For your project, check the professional’s qualifications, the affected materials and the planned method before work begins.
Is an existing inventory enough before renovation?
An older report is not automatically invalid. Check whether it covers the materials the contractor will disturb, including hidden layers. This also applies to professional work in a private home. A clearly limited intervention does not necessarily require a new inventory of the entire house.
