If any building, fence or other structure, or any tree, hedge or shrub, extends near to or in any manner encroaches upon any part of any street, alley or sidewalk so as to interfere with the public safety or convenience, the Chief of Police shall serve notice upon the owner or occupant of the premises where such encroachment exists or, if the premises are unoccupied and the owner is a nonresident, then by posting such notice in a conspicuous place upon the premises, specifying the extent and location of such encroachment and requiring the owner or occupant to remove the same within thirty days. Refusal or failure to comply with such notice shall be deemed a violation of this chapter.
