Summary

Unincorporated Bannock County folds wildfire-interface construction standards into its building code by adopting the International Wildland-Urban Interface Code, 2018 edition. Section 15.04.040(G) lists the IWUIC as part of the Bannock County Building Code alongside the IBC and IRC, so covered construction in the unincorporated county must meet that adopted code's requirements, enforced by the county building official under the same permit and penalty scheme as the rest of the building code.

These county ordinances apply to unincorporated areas of Bannock County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The purpose of this building code ordinance is to promote the health, safety and general welfare of the occupants or users of buildings and structures subject to this chapter by requiring minimum performance standards for construction and construction materials consistent with accepted standards of engineering, fire safety, life safety, energy efficiency, and accessibility. ... G.International Wildland-Urban Interface Code (IWUIC), 2018 Edition; ... D.Legal Action. Any person who violates any provisions of this chapter, or the codes adopted herein, shall be guilty of a misdemeanor, punishable as provided in Idaho Code Section 39-4126.

Full Breakdown

Bannock County's Board of County Commissioners adopted the current building code, including the IWUIC, by Ordinance No. 2020-07, effective December 29, 2020, replacing the prior Title 15. Section 15.04.020 grounds the whole building code in Article 12, Section 2 of the Idaho Constitution and Title 39, Chapter 41, Idaho Code, and Section 15.04.030 states the purpose as protecting health, safety and welfare through minimum performance standards for construction, including fire safety and life safety. Section 15.04.040 lists the IWUIC, 2018 edition, as one of nine model codes making up the Bannock County Building Code for all unincorporated areas, alongside the IBC, IRC, IECC, IEBC, ISEP, ISPSC and the Uniform Code for the Abatement of Dangerous Buildings.

Agricultural buildings on land actively farmed, as defined by Idaho Code Sections 39-4116(5) and 63-604, are exempt from these codes under Section 15.04.050, though they must still meet county zoning placement rules. The building official administers and enforces the adopted codes under Section 15.04.110, and may request comment or approval from other agencies before issuing permits or a certificate of occupancy under Section 15.04.120. Anyone affected by a building official decision on a code requirement can appeal within ten calendar days to the board of appeals under Section 15.04.170, though the board cannot waive any code requirement outright.

Violations & Fines

Any person who violates the adopted building code, including the IWUIC provisions folded into it, is guilty of a misdemeanor under Section 15.04.160(D), punishable as provided in Idaho Code Section 39-4126. The county first tries a voluntary compliance agreement with a deadline to fix the problem, but each day a violating structure remains out of compliance counts as a separate offense, and a court-ordered fine can be recorded as a lien on the property under Section 15.04.160(E).

Frequently Asked Questions

Does Bannock County have its own wildfire building code?
The county does not write its own wildfire code; instead Section 15.04.040(G) adopts the International Wildland-Urban Interface Code, 2018 edition, by reference as part of the Bannock County Building Code for all unincorporated areas, so IWUIC requirements apply directly under county law.
Are farm buildings exempt from the wildfire building code?
Yes. Section 15.04.050 exempts agricultural buildings on land actively devoted to farming, as defined by Idaho Code Sections 39-4116(5) and 63-604, from the adopted building codes, though they must still meet placement standards in the county zoning ordinance and cannot be used for human habitation or product processing.
Who enforces IWUIC compliance in unincorporated Bannock County?
The Bannock County building official administers and enforces the entire adopted building code, including the IWUIC, under Section 15.04.110, and may require comment or approval from other affected county agencies before issuing a permit or a certificate of occupancy, as set out in Section 15.04.120.
What happens if I violate the wildfire code requirements?
A violation of any adopted building code provision, including IWUIC standards, is a misdemeanor under Section 15.04.160(D), punishable under Idaho Code Section 39-4126, and the county can record a court-ordered fine as a lien on the property under Section 15.04.160(E) until it is paid.
