Summary
In unincorporated Bannock County, building a permanent or deep swimming pool requires a building permit under the county's adopted International Swimming Pool and Spa Code and its own amendment to the residential code's exempt-work list. Section 15.04.200 rewrites IRC Section R105.2 so only prefabricated pools four feet deep or shallower skip the permit process; anything deeper needs a permit, plans and inspection through the building official.

Full Breakdown
Section 15.04.040(F) folds the International Swimming Pool and Spa Code, 2018 edition, into the Bannock County Building Code for all unincorporated areas, alongside the IBC and IRC. When the county adopted the 2018 International Residential Code in Section 15.04.200, it deleted item 7 under the 'Building' subheading of Section R105.2, Work exempt from permit, and replaced it with a narrower exemption: only prefabricated swimming pools four feet deep or less skip the permit requirement, so in-ground pools and deeper prefabricated pools need a building permit before construction.
The building official administers this permitting under Section 15.04.110 and may coordinate with other agencies before approving a permit or certificate of occupancy under Section 15.04.120. Fees for the pool permit are set under Section 15.04.140 using the ICC Building Valuation Data Table published each February, with a regional cost modifier applied to the type of construction, and the fee schedule in Appendix A's Table No. 1-A runs from a flat $23.00 for work valued under $500 up through $5,608.75 plus $3.15 per additional $1,000 for projects over $1,000,000.
An applicant who disagrees with a building official's decision on a pool permit has ten calendar days to request a hearing before the board of appeals under Section 15.04.170.
Violations & Fines
Constructing an in-ground pool, or a prefabricated pool deeper than four feet, without the required building permit violates Section 15.04.200's amendment to IRC Section R105.2 and the adopted ISPSC standards under Section 15.04.040(F). Under Section 15.04.160(D), any violation of the adopted building code is a misdemeanor punishable as provided in Idaho Code Section 39-4126, and each day the unpermitted pool remains in place can count as a separate violation, with a court-ordered fine recordable as a lien on the property under Section 15.04.160(E).
