If you are only doing interior cosmetic renovations, a permit is not required. However, if the building's facade is being altered (e.g., cutting out a new panoramic window, changing a door's location) or if modifications are made to load-bearing structures, you must obtain an official permit from the City Hall Architectural Service. Additionally, food service establishments must pre-comply with the National Food Agency (NFA) standards (HACCP).

In office renovations, the primary focus is on soundproofing, comfortable work zones, and low-voltage systems (abundance of internet cables and sockets). For food service spaces, the priorities are setting up heavy-duty kitchen exhaust systems, installing grease traps, adhering to strict fire safety codes, and ensuring robust plumbing.
