Whenever necessary to make an inspection to enforce any ordinance, or whenever there is reasonable cause to believe that there exists an ordinance violation in any building or upon any premises within the jurisdiction of the City, any authorized official of the City may, upon presentation of proper credentials, enter such building or premises at all reasonable times to inspect the same and to perform any duty imposed upon such official by ordinance; provided that, except in emergency situations, such official shall first give the owner and/or occupant, if they can be located after reasonable effort, 24-hour written notice of the authorized official’s intention to inspect. In the event the owner and/or occupant refuses entry, the official is empowered to seek assistance from any court of competent jurisdiction in obtaining such entry.
