whether the pavement decoration has anything to do with the sanitation department depends on which industry you are engaged in, whether it will produce dust or smoke.

Like catering, it definitely needs to be related to sanitation. At present, the kitchens of catering need to be cleaned with smoke before they can be blocked, and the smoke should be discharged to the designated direction and position.

for shops, they usually deal with the urban management. Your door decoration needs to be approved by the urban management, and only if it meets the requirements of urban and street planning. Some shops also need to deal with the fire and health departments. You can consult the municipal government service center or street office in detail.

I hope I can help you.
