Whenever the Building Commissioner orders a structure or premises, or part thereof, to be vacated, repaired or demolished, he shall cause to be posted at each entrance to such structure or premises, or part thereof, a placard ordering such vacation, repair or demolition. No person shall deface or remove such placard until the repairs or demolition are completed, without written permission of the Building Commissioner. No person shall enter or use any structure or premises so placarded except for the purpose of making the required repairs or demolishing the structure or premises. (Ord. 21-1980. Passed 5-13-80.)
