Ordinance No. 15-2025 is codified on Municode (a JavaScript single-page application at library.municode.com/co/wellington); bare curl/automated fetch still returns HTTP 200 with no static text, but CORRECTED 2026-07-23: the full codified text IS retrievable via a live browser session (Municode renders client-side JS content that a headless curl fetch cannot execute) — confirmed directly against Chapter 18, Articles 1-4 (IBC/IRC/IPC/IMC amendments), version 'JUL 10, 2026 (CURRENT)', which quotes Ordinance No. 15-2025's full section-by-section amendment text verbatim, including the IRC R401.2 foundation/soils-report amendment. The Town's own Building Department webpage 'Building Departments News & Update' section (dated 11.25.2025) remains a valid corroborating first-party source for the adoption dates.; Previous code cycle (through December 31, 2025, now superseded): 2018 International Code editions (IBC, IRC, IECC, IMC, IPC, IFGC, IPMC, IEBC, IFC) under Ordinance No. 5-2019, and 2023 NEC. The Town's own Contractors/Homeowners webpages still host several 2018-cycle 'SAFEbuilt Building Guide' packets (Re-Roof 2018, Accessory Structure 2018, Deck/Porches 2018, Patio Covers 2018, Pole Barn 2018, Swimming Pools 2018, PV System 2019) that have not yet been refreshed to reference the 2024 I-Codes as of this review — treated as legacy/stale content rather than the governing code list, consistent with the Town's own live 'Current (Effective January 1, 2026)' code list.. Local amendments apply — see the Wellington overview page for the full list.

SAFEbuilt, a third-party firm contracted by the Town of Wellington, conducts plan review and inspections on behalf of the Town's Planning and Building Department. Applications, payments, and scheduling still go through the Town's Community Core/Connect portal.
