Any member of the Bureau and any Fire Inspector may, at all reasonable hours and/or at any time he or she has reason to believe that a fire hazard may exist, enter any building or structure within his or her respective jurisdiction, except the interior of a private residence, for the limited purpose of performing an inspection regarding any conditions suspected of constituting a threat to the safety of the building or its occupants. Any member of the Bureau, or any duly appointed Fire Inspector, may enter a private residence only with the consent of the owner or its occupants, unless exigent circumstances warrant immediate entry to protect human health, safety and welfare.
