Can I skip the property audit when changing the signboard?

You can't. The property needs to check whether the signs on the pavement are damaged by stones, walls, insulation layers, etc. Positive. These parts belong to public * * * parts, and have interests with neighboring enterprises. Signboard design drawings need to be left to the property company for filing, which will affect the structural load-bearing, wind resistance, light pollution, lighting of neighboring businesses, blocking the line of sight, etc.
