Brighton, Colorado has adopted: 2021 International Building Code (IBC) — City of Brighton 'Building Code Editions, Design Loads, Etc.' sheet, Codes & Information page; 2021 International Residential Code (IRC); 2021 International Mechanical Code (IMC); 2021 International Plumbing Code (IPC); 2021 International Fuel Gas Code (IFGC); 2021 International Fire Code (IFC); 2021 International Energy Conservation Code (IECC); 2021 International Property Maintenance Code (IPMC); 2021 International Existing Building Code (IEBC); 2021 International Swimming Pool and Spa Code (ISPSC); 2023 National Electrical Code (NEC); ICC A117-17 (Accessible and Usable Buildings and Facilities); Effective date of the 2021 I-Code revisions: January 1, 2023. Effective date of the 2023 NEC adoption: July 1, 2023 — both per the City's own published 'Building Code Editions, Design Loads, Etc.' sheet (Codes & Information page), which is treated as the current, governing adopted-code list for this file.; Note on code-page currency: Brighton's Municode-hosted Chapter 15, Article 15-12 ('National Electrical Code') still codifies the '2005 National Electrical Code' verbatim in its Municode text — this is a known lag between the codified ordinance text on Municode and the live, actively-maintained Codes & Information page, which explicitly states the 2023 NEC is adopted effective 7/1/2023. The live department page is treated as authoritative for current code edition, consistent with the same lag pattern documented for other Colorado home-rule jurisdictions in this corpus (e.g. Vail's Minimum Submittal Requirements PDFs).. Local amendments apply — see the Brighton overview page for the full list.

Only if the scope involves a new foundation or structural changes. A straightforward interior remodel not affecting structural elements does not require these documents, per the City's checklist guidance.
