Hudson, Colorado has adopted: 2018 International Building Code (IBC), as codified and amended per Hudson Municipal Code Chapter 18, Article I, Sec. 18-2 (Ord. No. 19-13, 7-3-19) — currently in force per the live Municode-codified chapter; 2018 International Residential Code (IRC), Sec. 18-6 (Ord. No. 19-13, 7-3-19) — currently in force; 2018 International Mechanical Code (IMC), Sec. 18-10 (Ord. No. 19-13, 7-3-19) — currently in force; 2018 International Fuel Gas Code (IFGC), Sec. 18-20 (Ord. No. 19-13, 7-3-19) — currently in force; 2018 International Plumbing Code (IPC), Sec. 18-24 (Ord. No. 19-13, 7-3-19) — currently in force; 2012 International Energy Conservation Code (IECC), Sec. 18-28 (Ord. No. 19-13, 7-3-19) — currently in force per the live-codified chapter, though the Town's own DRAFT 2024 amendments propose replacing this with the 2024 IECC (status: not yet adopted as of this review); 2018 International Property Maintenance Code (IPMC), Sec. 18-32 (Ord. No. 19-13, 7-3-19) — currently in force; 2018 International Existing Building Code (IEBC), Sec. 18-36 (Ord. No. 19-13, 7-3-19) — currently in force; 2018 International Swimming Pool and Spa Code (ISPSC), Sec. 18-40 (Ord. No. 19-13, 7-3-19) — currently in force; National Electrical Code: no locally adopted NEC edition found in Chapter 18; IPMC Section 604.2 as amended defers to 'the Electrical Code adopted by the State of Colorado' rather than naming a specific NEC edition — electrical work in Hudson is administered under the Colorado State Electrical Board framework (see localAmendments); IMPORTANT STATUS NOTE — code edition transition in progress but NOT yet finalized: the Town's live Building Permits & Inspections page (hudsonco.gov/166/Building-Permits-Inspections) states the Town 'will adopt the 2024 ICC codes beginning June 2026, including Solar and EV-ready provisions,' and the Town has posted a document titled 'DRAFT 2024 Building Code Amendments' (DocumentCenter View/6523) proposing 2024 editions of IBC/IRC/IMC/IFGC/IPC/IECC(2024)/IPMC/IEBC/ISPSC plus a new Colorado Model Electric and Solar Ready Code, 2023 Edition (Title 31, Article 16, Part 2, C.R.S.) as Sec. 18-43. However, that document is watermarked 'DRAFT' throughout (dated 4/02/2026) and the live, currently-codified Municode text of Chapter 18 (confirmed via search-engine cache of library.municode.com/co/hudson, page directly 403'd to automated fetch) still shows the 2018/2012 editions listed above as being in force via Ord. No. 19-13. Per this project's zero-tolerance policy, the 2024 suite is NOT recorded as adopted until a signed ordinance/Municode update is confirmed; codesAdopted above reflects the current in-force 2018/2012 baseline, with this note flagging the pending transition for the next verification pass.; Separately, the Hudson Fire Protection District (HFPD) — an independent special district, not a Town department — has its own fire-code adoption process. The Town's live Building page states 'The Hudson Fire Protection District Board has adopted the 2024 IFC amendments, with draft documents available for review,' and a scanned board resolution (DocumentCenter View/6549, '2024-IFC-Adoption-Board-Resolution', a Konica Minolta scan dated April 2026) is posted. The underlying scanned PDF could not be OCR'd/text-extracted directly during this research pass (image-only scan, no embedded text layer) and the HFPD's own website (hfpdco.org) does not independently confirm a specific in-force IFC edition on the pages checked. Treated as partial confidence: an HFPD board resolution exists and the Town references it as adopted, but the specific currently-effective IFC edition enforced Town-wide could not be independently corroborated beyond the Town's own page summary.. Local amendments apply — see the Hudson overview page for the full list.
