Preston adopts state-adopted building code, repeals outdated Title 15

Preston City Council voted unanimously to repeal its old Title 15, which had last been substantially updated decades ago, and to adopt the state‑adopted building codes — principally the 2018 International Building Code with Idaho amendments and related Idaho code editions. The ordinance package lists specific codes adopted: the 2018 International Building Code (IBC), Idaho residential code (2020 edition), 2018 International Existing Building Code, 2023 NEC electrical code with amendments, elevator codes as approved by the Idaho Division of Occupational and Professional Licenses, and related mechanical, fuel gas and fire codes.

Kurt Fuller, the city’s building inspector, told the council the change provides a single, formal reference for builders and inspectors and reduces confusion created by the city’s older, out‑of‑date citations. “Responsible to build to code,” Fuller said, summarizing the inspector’s perspective on enforcement. Council also adopted the Idaho Standards for Public Works Construction (ISPWC) for roads and site work and discussed developing supplemental Preston‑specific standards with Keller & Associates. The clerk read Ordinance 2026‑3 in summary and the council approved the ordinance on a roll‑call vote.

Council members said the update should make inspections and permit reviews more consistent with state practice while preserving the council’s ability to adopt local amendments (for example, the council affirmed retaining a 120‑square‑foot permit exemption for sheds rather than the state’s 200‑square‑foot threshold).
