When is a permit needed?
It depends on the property and the work planned. Painting, flooring, kitchen, bathroom, electrical or plumbing work that does not affect the structure, the facade or the layout generally counts as maintenance and routine renovation. As soon as the structure, the facades, the openings, the volume or the use change, or if the building is protected or subject to the LDTR, a building permit and a representative are required in Geneva. Before starting, have your project checked by your architect, your MPQ or the Department of Territory. The procedures are explained on the “applying for a building permit” page of the State of Geneva. MS Contractor SA prepares the file with your representative and carries out the planned work.
As soon as the project moves a partition, creates an opening, changes the use of a room, affects the facade or extends the building, a permit becomes necessary. It is in this case that we prepare the application with you and call on a partner architect when the file requires it.
