Platteville, Colorado has adopted: 2024 International Building Code (IBC), Chapters 1-35 — CONFIRMED 2026-07-23 directly from the Town's own codified ordinances (Sec. 18-2-10, 'Adoption', Chapter 18 — Building Regulations, Article II — Building Code): 'The International Building Code, 2024 Edition as published by the International Code Council, 4051 West Flossmoor Road, Country Club Hills, IL 60478, Chapters 1 through 35 inclusive...'

Chapters 1 through 43 inclusive...' Corroborates the SAFEbuilt guide series' consistent '2024 IRC' heading with a second, independent, directly-codified source.; 2024 International Mechanical Code (IMC), Chapters 1-15 — CONFIRMED 2026-07-23 via Sec. 18-3-10 'Adoption' (Chapter 18, Article III — Mechanical Code), live Municode text.; 2024 International Fuel Gas Code (IFGC), Chapters 1-8 — CONFIRMED 2026-07-23 via Sec. 18-9-10 'Adoption' (Chapter 18, Article IX — Fuel Gas Code), live Municode text.; 2024 International Fire Code (IFC), plus Appendix B-0 — CONFIRMED 2026-07-23 via Sec. 18-11-10 'Adoption' (Chapter 18, Article XI — Fire Code): 'chapters and appendices B-0 of the 2024 International Fire Code (the "IFC") are hereby adopted by reference as the Town of Platteville Fire Code...'; 2024 International Property Maintenance Code (IPMC), Chapters 1-8 — CONFIRMED 2026-07-23 via Sec. 18-12-10 'Adoption' (Chapter 18, Article XII — Property Maintenance Code), live Municode text.; 2024 International Existing Building Code (IEBC), Chapters 1-16 — CONFIRMED 2026-07-23 via Sec. 18-13-10 'Adoption' (Chapter 18, Article XIII — Existing Building Code); this code family was not previously identified in this file — new finding from the 2026-07-23 chase.; 2024 International Energy Conservation Code (IECC), Chapters 1-6 Commercial [+ Residential provisions] — CONFIRMED 2026-07-23 via Sec. 18-14-10 'Adoption' (Chapter 18, Article XIV — Energy Conservation Code), which ALSO adopts by reference 'Appendix CK Colorado Model Electric and Solar Ready Code-Commercial and Appendix RM Colorado Model Electric and Solar Ready Code-Residential' — this is the direct, specific HB22-1362 electric-ready/solar-ready citation that could not be located in 2026-07-06's chase (only the generic 'State of Colorado Electric Ready Code' guide reference was found then). Sec. 18-14-30 'Amendments' further amends the IECC to replace all references to 'ICC Electrical Code' with 'National Electrical Code as adopted by the State.'; National Electrical Code (NEC), 2023 Edition, exclusive of appendices — CONFIRMED 2026-07-23 via Sec. 18-5-10 'Adoption' (Chapter 18, Article V — Electrical Code): 'The National Electrical Code, 2023 Edition, exclusive of appendices, published by the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02169, is hereby [adopted]...' This RESOLVES the gap flagged in the 2026-07-06 pass ('The NEC edition... could not be independently re-confirmed... omitted rather than guessed') — Platteville does codify its own NEC edition (2023) in Chapter 18 Article V, notwithstanding that day-to-day electrical licensing runs through DORA contemporaneous review rather than a Town trade-license program (see localAmendments).; All nine code-family adoptions above were retrieved 2026-07-23 from the Town's live, current Municode Library codification (library.municode.com/co/platteville/codes/code_of_ordinances), Supplement 2, online content updated 2026-02-17, 'Codified through Ordinance No. 2025-851, enacted December 16, 2025' — via that page's own full-text search API (localapi/search, clientId=19046, scoped to Platteville only), which returns live indexed section text. This is a second, independent, more authoritative confirmation of the 2024 cycle than the SAFEbuilt guide series alone, and definitively supersedes the stale 'Photovoltaic System Submittal Requirements' PDF (last revised 10.22.2021, citing '2020 NEC, 2018 International Codes') — that PDF's code-year language is now confirmed stale against the Town's own codified ordinances, not merely inferred against a differently-dated guide series.; Colorado is a home-rule state with no statewide-mandated building code edition; Platteville's own codified Chapter 18 adoption ordinances (as amended through Ord. No. 2025-851, Dec. 16, 2025) are the direct governing source, corroborated by the SAFEbuilt guide series.; HB22-1362 (Colorado's statewide minimum energy code floor for the July 2023-July 2026 window, requiring at least the 2021 IECC plus electric- and solar-ready / EV-ready provisions for jurisdictions issuing residential building permits) is satisfied and directly evidenced: Platteville's 2024 IECC adoption (Sec. 18-14-10) exceeds the 2021 IECC floor AND explicitly adopts by reference the Colorado Model Electric and Solar Ready Code Appendices CK (Commercial) and RM (Residential) — the specific state-mandated electric-ready/solar-ready provisions, confirmed 2026-07-23 directly from the ordinance text rather than inferred from a generic guide-page mention.. Local amendments apply — see the Platteville overview page for the full list.

Per the Town's Uncovered Decks & Porches guide (2024 IRC), any deck 30 inches or more above finished grade requires a 36-inch guardrail.
