Ault, Colorado has adopted: 2024 International Residential Code (IRC) — per the '2026 SAFEbuilt Residential Application Check List' (Town of Ault Building Permits page, Helpful/Residential resource): 'All submittal information must comply with the 2024 I-codes and the 2023 NEC.'; 2024 International Building Code (IBC) — per the SAFEbuilt 'New Commercial Plan Submittal Procedure' and 'Commercial Tenant Finish/Remodel Plan Submittal Procedure' documents on the Town of Ault Building Permits page, both headed '2024 INTERNATIONAL CODES.'; 2024 International Energy Conservation Code (IECC) — required compliance documentation (ResCheck or energy rating report) explicitly named in the SAFEbuilt Residential Application Check List; commercial submittal procedures likewise require 'Documentation showing compliance with the 2024 IECC.'; 2023 National Electrical Code (NEC) — explicitly named in the SAFEbuilt Residential Application Check List ('...and the 2023 NEC').; 2024 International Mechanical Code (IMC) / International Plumbing Code (IPC) — inferred from the SAFEbuilt submittal procedures' consistent requirement of 'Mechanical/Plumbing Plans' stamped by a Colorado-licensed engineer, cross-referenced against the same '2024 INTERNATIONAL CODES' heading used for the IBC/IECC citation on the same documents; not independently named by edition number in the source text, so carried at 'partial' confidence for the specific IMC/IPC edition number. 2026-07-23 re-chase: the Town's own codified Municipal Code (Title 15 Ch.04, Sections 030/060), recovered via Wayback Machine archive of the now-defunct myaultgov.org portal (Sec. 030 Mechanical captured 2022-12-05: 'International Mechanical Code, 2018 Edition'; Sec. 060 Plumbing captured 2022-12-05: 'International Plumbing Code, 2012 Edition'), shows both trade codes were LAST codified at pre-2024 editions — older than, and in unresolved tension with, SAFEbuilt's current 2024-I-code submittal language; no live, currently-hosted Municipal Code exists to confirm whether these sections have since been amended to 2024 editions, so the specific currently-governing IMC/IPC edition numbers remain genuinely unconfirmed and are NOT asserted as '2024' anywhere in this file.; 1997 Uniform Building Code (UBC), Table 1-A — still the operative VALUATION-BASED FEE TABLE per the Town's 'Building Permit Fee Schedule' (Exhibit B — Fee Schedule for Services, a SAFEbuilt consultant-services fee exhibit posted on the Town's Building Permits resource list, last modified 5/19/24). This is a fee-calculation table, not a life-safety code edition, and is retained purely because it is the Town's actual current, published fee mechanism — it does not indicate the Town is still enforcing 1997 UBC life-safety provisions, which are superseded by the 2024 I-codes cited above.; No separate Ault-specific building-code-adoption ordinance was found published online: the Town of Ault Municipal Code page (aultcolorado.gov/MuniCode) states 'A Copy of the Ault Municipal Code is Available Upon Request' and is not hosted on Municode/eCode360 or any other public code-hosting platform; the Town's online Document Archive 'Ordinances' folder contains only a 'Non-Certified Copy of 2024 Model Traffic Code' (unrelated to building codes). The SAFEbuilt submittal-requirement documents (which explicitly compel 2024 I-code / 2023 NEC compliance and are hosted directly on the Town's own Building Permits page) are therefore treated as the governing, currently-operative code-adoption source for this file, consistent with SAFEbuilt Colorado being Ault's contracted building official/plan-review/inspection provider (per Exhibit B of the Town-SAFEbuilt consultant services agreement).. Local amendments apply — see the Ault overview page for the full list.
