Idaho Code § 50-1326
For the purposes of sections 50-1326 through 50-1329, Idaho Code, any plat of a subdivision filed in accordance with chapter 13, title 50, Idaho Code, or in accordance with county ordinances adopted pursuant to chapter 38, title 31, Idaho Code, shall be subject to the sanitary restriction. There shall be placed upon the face of every plat prior to it being recorded by the county clerk and recorder, the sanitary restriction, except such sanitary restriction may be omitted from the plat, or if it appears on the plat, may be indorsed by the county clerk and recorder as sanitary restriction satisfied, when there is recorded at the time of the filing of the plat, or at any time subsequent thereto, a duly acknowledged certificate of approval issued by the director of the department of environmental quality, for either public water and/or public sewer facilities, or individual water and/or sewage facilities for the particular land. The owner shall have the obligation of submitting to the director all information necessary concerning the proposed facilities referred to. Such certificate of approval may be issued for the subdivision or any portion thereof. Until the sanitary restrictions have been satisfied by the filing of said certificate of approval, no owner shall construct any building or shelter on said premises which necessitates the supplying of water or sewage facilities for persons using such premises. The sanitary restrictions shall be reimposed on the plat upon the issuance of a certificate of disapproval after notice to the responsible party and an opportunity to appeal, if construction is not in compliance with approved plans and specifications, or the facilities do not substantially comply with regulatory standards in effect at the time of facility construction.
