Is it illegal for the property to conceal civil air defense parking spaces?

Not illegal. According to relevant public information, civil air defense parking spaces are parking spaces built by developers in accordance with the provisions of the Civil Air Defense Law, and then converted into parking spaces. Civil air defense parking spaces are generally located on different floors of buildings, generally on the floors below ordinary parking spaces. The closed iron gate is one of the signs of civil air defense parking spaces. In some buildings, civil air defense parking spaces and ordinary parking spaces are located on the same floor and are divided according to different areas. From the use point of view, there is no difference between ordinary parking spaces and civil air defense parking spaces.
