The order shall be in writing; recite the grounds therefor; specify the necessary repairs, if any, and provide a reasonable time for compliance; and shall state that a motion for summary enforcement of the order will be made to the district court of the county in which the hazardous building or property is situated unless corrective action is taken, or unless an answer is filed within the time specified in section 463.18.
The order shall be served upon the owner of record, or the owner's agent if an agent is in charge of the building or property, and upon the occupying tenant, if there is one, and upon all lienholders of record, in the manner provided for service of a summons in a civil action. If the owner cannot be found, the order shall be served upon the owner by posting it at the main entrance to the building or, if there is no building, in a conspicuous place on the property, and by four weeks' publication in the official newspaper of the municipality if it has one, otherwise in a legal newspaper in the county.
A copy of the order with proof of service shall be filed with the court administrator of district court of the county in which the hazardous building or property is located not less than five days prior to the filing of a motion pursuant to section 463.19 to enforce the order. At the time of filing such order the municipality shall file for record with the county recorder or registrar of titles a notice of the pendency of the proceeding, describing with reasonable certainty the lands affected and the nature of the order. If the proceeding be abandoned the municipality shall within ten days thereafter file with the county recorder a notice to that effect.
