Iowa Code § 103A.12

(1) The state building code is applicable in each governmental subdivision of the state in which the governing body has enacted an ordinance accepting the applicability of the code and has filed a certified copy of the ordinance in the office of the commissioner. The state building code becomes effective in the governmental subdivision upon the date fixed by the governmental subdivision ordinance, which must not be more than six months after the date of adoption of the ordinance.

(2) A governmental subdivision in which the state building code is applicable may by ordinance, at any time after one year has elapsed since the code became applicable, withdraw from the application of the code. The local governing body shall hold a public hearing pursuant to section 362.3, together with written notice to the commissioner of the time, place, and purpose of the hearing, before the ordinance to withdraw is voted upon. A certified copy of the vote of the local governing body shall be transmitted within ten days after the vote is taken to the commissioner. The ordinance becomes effective at a time to be specified in the ordinance, which must be not less than one hundred eighty days after the date of adoption. Upon the effective date of the ordinance, the state building code ceases to apply to the governmental subdivision except that construction of a building or structure pursuant to a permit previously issued is not affected by the withdrawal.

(3) A governmental subdivision which has withdrawn from the application of the state building code may, at any time thereafter, restore the application of the code in the same manner as specified in this section.
