My family lives on the top floor, and one of the small rooms is not safe. Safety nets and property must be removed. I don't know the current rules of safety net.

According to property management, there are no hard and fast rules, but the significance of the existence of property companies is to preserve and increase the value of "properties" (generally referring to buildings). If you must follow them, please install protective windows outside the windows in drip line. drip line belongs to the owner's private space, and the property has no right to interfere. This not only meets its own requirements, but the property company will not stop it.

Good luck in the new year!
