Salida, Colorado has adopted: 2021 International Building Code (IBC) — adopted by the City of Salida per the City's own Building Permit Review page: 'The City adopted the 2021 International Codes for Building, Residential, Existing Buildings, Plumbing, Mechanical, Energy Conservation, Fuel Gas and Property Maintenance with the 2021 IECC and the 2021 National Electric Code.' Chaffee County Building Safety Department's own Adopted Codes & Design Criteria page independently confirms the same 2021 I-Code suite (IBC, IRC, IFC, IPC, IMC, IFGC, IECC, IEBC) is the edition actually enforced county-wide, including for Salida.; 2021 International Residential Code (IRC) — same dual-source confirmation as above; 2021 International Existing Building Code (IEBC); 2021 International Plumbing Code (IPC); 2021 International Mechanical Code (IMC); 2021 International Fuel Gas Code (IFGC); 2021 International Energy Conservation Code (IECC) — Chaffee County's Residential Building Application requires an IECC Compliance Path Certificate, Manual J/S/D submittal, and blower-door/duct/ventilation testing by a RESNET- or BPI-certified tester; 2021 International Property Maintenance Code — named on the City's own adopted-codes list; 2023 National Electrical Code (NFPA 70 / NEC) — City of Salida's own page states '2021 IECC and the 2021 National Electric Code,' but Chaffee County Building Safety Department's Adopted Codes & Design Criteria page (the agency that actually issues and enforces electrical permits) lists the 2023 NEC as currently adopted; this is a genuine, honestly-flagged discrepancy between the City's own page text and the County's live enforced edition — applicants should confirm the currently enforced NEC edition directly with Chaffee County Building Safety Department at time of submittal; 2017 ICC A117.1 Accessible and Usable Buildings and Facilities — Chaffee County Adopted Codes & Design Criteria page; Colorado Wildfire Resiliency Code (effective July 1, 2026) and 2021 International Wildland-Urban Interface Code (IWUIC) — Chaffee County Adopted Codes & Design Criteria page; note several IWUIC-specific submittal requirements on the County's own Residential Building Application are explicitly scoped to 'Unincorporated Chaffee County Only,' meaning some (not all) IWUIC provisions may not directly apply within Salida city limits — confirm scope with the County Building Department for any given IWUIC provision; Colorado Model Electric Ready & Solar Ready Code — Chaffee County Adopted Codes & Design Criteria page; the County's Residential Building Application requires roof load design for future solar panels and a solar-ready zone/interconnection pathway on submitted plans; Salida Municipal Code Chapter 16, Land Use and Development — governs zoning compliance, setbacks, dimensional standards, landscaping, and parking; reviewed by the City of Salida Community Development Department as the mandatory first step before any County building-permit review begins.
