A building permit or permit is an official document given by the municipality to the owner or contractor, during which it is allowed to start and continue the construction or renovation project according to certain criteria. It is obvious that carrying out any construction operation without issuing a building permit is illegal and will be stopped by the building supervision authorities. These rules and standards are intended to ensure the safety of the current or future owners of the building. The most important goal of obtaining a construction permit is to ensure legal construction in accordance with technical indicators and following the principles of urban planning in accordance with the regulations and rules of the master plan. Among the other benefits of obtaining a license, we can mention the benefit of banking facilities, the insurance of the building and the people working in the building, the prevention of construction accidents, and the use of technical and engineering experiences in the construction of the building.
