Building permits

Before beginning construction on your building, you must obtain a building permit; otherwise, you risk having the work halted. The application for a building permit must be submitted to the mayor.

This application must include information about the owner and the exact location of the property. It must also describe the proposed work and be accompanied by a file containing the following documents, to be submitted in duplicate:

• a cadastral extract;
• a certificate issued by the Order of Architects and Certified Engineers;
• construction drawings on a scale of 1:100 or 1:50;
• a survey conducted by a licensed surveyor.

Construction plans must include:

• floor plans of all levels, including the basement and attic, showing the shape of the roof;
• These plans will provide information on ventilation systems, fireplaces, and chimneys;
• The longitudinal and cross-sectional views necessary for the study of the construction project, showing the existing topography of the site and the planned modifications;
• Elevation views of all facades, showing the levels of the courtyards, the gradients of public roads, and the facades of existing adjacent buildings.

As a general rule, all plans must be prepared and signed by a licensed architect or structural engineer. They must be countersigned by the building owner(s). All documents must be submitted folded to DIN A4 size, with margins, and clearly labeled to indicate their contents.
