Idaho Code § 67-4612: Special restrictions.

In addition to any power or authority of a county or city to regulate by planning or zoning laws and regulations or by local laws and regulations, the governing body of any county or municipality is empowered to provide by ordinances, special conditions or restrictions for the protection, enhancement and preservation of historic properties; provided however, that nothing in this chapter shall authorize or be construed to allow the designation, regulation, conditioning or restriction by ordinance or other means of any property or facility owned by the state of Idaho.
