Whenever the building or structure has been so damaged by fire, wind, earthquake or flood, or has become so dilapidated or deteriorated by any cause or is in any stage of demolition such that it becomes an attractive nuisance to children, a harbor for vagrants, criminals or other persons, or as to enable persons to resort thereto for the purpose of committing a nuisance or unlawful acts; or

  2. Whenever, for any reason, the building or structure, or any portion thereof, is manifestly unsafe for the purpose for which it is being used.
