Idaho Code § 31-3908A
The board of county commissioners, upon application, may, by an ordinance enacted by not later than the second Monday of July, exempt all or a portion of the unimproved real property within the district from taxation, and may exempt all or a portion of the taxable personal property within the district from taxation. Any ordinance of the board of county commissioners granting an exemption from taxation under the provisions of this section must provide that each category of property is treated uniformly. Notice of intent to adopt an ordinance which exempts unimproved real property shall be provided to property owners of record in substantially the same manner as required in section 67-6511(2)(b), Idaho Code, as if the ordinance were making a zoning district boundary change.
