Broomfield, Colorado has adopted: Colorado is a home-rule state with NO single statewide building code — each municipality and county adopts and amends its own code edition(s). The only statewide floor requirements are energy-code related (HB22-1362, the Colorado Energy Code Board / Model Low Energy and Carbon Code process) and, for accessory dwelling units, HB24-1152 (statewide ADU standards for eligible jurisdictions). Applicants working in any other Colorado city or county must independently confirm that jurisdiction's own adopted code edition and amendments — do not assume Broomfield's editions apply elsewhere.

The City's Building Division page still carries unchanged 2025-vintage text (re-fetched live 2026-07-23, identical to the 2026-07-18 and 2026-07-03 captures) stating Broomfield had not yet held its adoption hearing and was not expected to consider adoption until early 2026. The dedicated Broomfield Voice WUI page (also re-fetched live 2026-07-23, unchanged since its 2026-04-15 update) is more current and explicit: as of its last update the Wildfire Resilience Code 'has not been adopted by Broomfield,' hearing dates are 'not yet set,' and adoption-ordinance readings 'are not anticipated to occur until the second half of 2026.' Both the March 1, 2026 statewide adoption deadline and the June 1, 2026 enforcement deadline have now passed with no adoption on record on either page — Broomfield's WUI code is not yet in effect as of today.
