If, after a preliminary investigation of any dwelling, building, structure, or premises, the building inspector finds that it is unfit for human habitation or other use, he or she shall cause to be served either personally or by certified mail, with return receipt requested, upon all persons having any interest therein, as shown upon the records of the Stevens County Auditor’s office, and shall post in a conspicuous place on such property, a notice/complaint stating in what respects such dwelling, building, structure, or premises is unfit for human habitation or other use. If the whereabouts of any of such persons is unknown and the same cannot be ascertained by the building inspector in the exercise of reasonable diligence, and the building inspector makes an affidavit to that effect, then the serving of such notice/complaint or order upon such persons may be made either by personal service or by mailing a copy of the notice/complaint and order by certified mail, postage prepaid, return receipt requested, to each such person at the address of the building involved in the proceedings, and mailing a copy of the notice/complaint and order by first-class mail to any address of each such person in the records of the Stevens County Assessor or the Stevens County Auditor. Such notice/complaint shall contain a notice that a hearing will be held before the building inspector, at a place therein fixed, not less than ten days nor more than thirty days after the serving of the notice/complaint; and that all parties in interest shall be given the right to file an answer to the notice/complaint, to appear in person, or otherwise, and to give testimony at the time and place in the notice/complaint. This hearing shall take place in front of the building inspector. The rules of evidence prevailing in courts of law or equity shall not be controlling in hearings before the building inspector. A copy of such notice/complaint shall also be filed with the Stevens County Auditor, and such filing of the notice/complaint or order shall have the same force and effect as other lis pendens notices provided by law.
