Basalt, Colorado has adopted: 2021 International Building Code (IBC) as locally amended by Town of Basalt Ordinance (Chapter 18 amendments effective July 20, 2023) — confirmed via the Town's own 'Building' page code-adoption summary ('2021 ICC') and via the Town's detailed strike-through/underline local-amendment comparison document (2021-Code-change--ICC-reference-articles, basalt.net/DocumentCenter/View/6221); 2021 International Residential Code (IRC), as locally amended — the Town's own Building Permit Application Checklist is titled for 'Single Family, Duplex, and Townhomes' built to the IRC; 2021 International Mechanical Code (IMC); 2021 International Fuel Gas Code (IFGC) — State of Colorado adopted edition referenced alongside the Town's 2021 IBC/IRC/IMC cycle; 2021 International Existing Building Code (IEBC); 2021 International Plumbing Code (IPC) — adopted at the State of Colorado level and applied by the Town; 2023 National Electrical Code (NEC) — per the Building Department page's current-adoptions summary; NOTE electrical work in Basalt is permitted and inspected by the State of Colorado Electrical Board, not the Town Building Department itself (confirmed directly on the Town's own Building Permit Application form: 'Electrical is permitted and inspected by the State of Colorado'); 2024 Sustainable Building Regulations I & II (SBRI/SBRII) — Town of Basalt Municipal Code Sec. 18-23/18-24/18-25, amended by Ordinance 20, Series of 2024, effective November 12, 2024, reflecting Holy Cross Energy's approximately 90% renewable power supply achievement by end of 2024; Prior/superseded local design-parameter reference: the Town's 'Local Structural Design Parameters' document (basalt.net/documentcenter/view/2388) still headers itself against the 2015 IBC/IRC/IMC/IECC/IEBC code cycle and 2017 NEC/2015 IPC-IFGC — the numeric structural design values on that document (ground snow load, wind speed, seismic category, frost depth) are treated as still-current in this file because the Town's later 2021-code-adoption amendment document (View/6221) re-adopts the identical IRC Table R301.2(1) frost-depth (36 inches) and retaining-wall figures verbatim rather than superseding them; the code-EDITION labels on that older PDF itself are NOT current and should not be read as Basalt's current adopted code cycle.; Local amendments to all adopted codes are codified in Chapter 18 (Building Regulations) of the Basalt Municipal Code; Municode's Basalt library returned an HTTP 403 to direct automated fetch in this session (library.municode.com/co/basalt) — the Town's own downloadable strike-through/underline amendment comparison document (View/6221) was used as the authoritative source for specific local IBC/IRC section amendments instead, since it is a primary Town document rather than a third-party mirror.. Local amendments apply — see the Basalt overview page for the full list.
