Dacono, Colorado has adopted: 2024 International Building Code (IBC) — City of Dacono Building Codes page, adopted for all new permit submittals; 2024 International Residential Code (IRC); 2024 International Fuel Gas Code (IFGC); 2024 International Plumbing Code (IPC); 2024 International Mechanical Code (IMC); 2024 International Existing Building Code (IEBC); 2024 International Property Maintenance Code (IPMC); 2024 International Swimming Pool and Spa Code (ISPSC); 2024 International Energy Conservation Code (IECC); 2024 International Fire Code (IFC); 2023 National Electrical Code (NEC); Adopted via Ordinance 1002 (December 17, 2025, effective date of the 2024 code cycle) and subsequently amended by Ordinance 1010 (March 23, 2026); prior code cycle was adopted under Ordinance 949 (October 9, 2023). The City's live Building Codes webpage lists these three ordinances directly beneath the Adopted Codes list.; Colorado HB 1091 (Lofgren & Johnson Families Carbon Monoxide Safety Act) is separately cross-referenced on the City's Building Codes page as an applicable state law requiring carbon monoxide alarms under specified conditions — this is a state statute the City flags for awareness, not a City-adopted model code edition.; HB22-1362 (Colorado statewide energy code/electric- and solar-ready standard, applicable window July 2023-July 2026): Dacono's adoption of the 2024 IECC (effective December 17, 2025, per Ordinance 1002) falls within this window. The City's Building Codes page does not itself cite HB22-1362 or describe the 2024 IECC adoption as an HB22-1362 compliance action — this connection is inferred from the timing and code edition, not confirmed by an explicit City statement, so it is not asserted as a settled fact for any permit-level requirement in this file.. Local amendments apply — see the Dacono overview page for the full list.

Yes, if you apply as the homeowner (not through a contractor) during the City's 'Almost Free Building Permit Month' each June, for an alteration, repair, or improvement of an existing residential structure or associated accessory structure. New residential construction and non-residential projects do not qualify, and use tax still applies.
