Is it illegal to hang trusses in hotels?

Truss is a dangerous thing. If the hotel has not obtained the construction project planning permit, it is illegal to hang it at will.

Truss refers to truss beam, which is a lattice beam structure. Truss structures are often used in long-span buildings, such as factories, exhibition halls, gymnasiums and bridges. Trusses are usually called roof trusses because they are mainly used for building roof structures.
