IMPORTANT: the Town's Building Division page names ONLY the 2024 IBC, 2024 IFC, and Colorado Wildfire Resiliency Code as recently updated — it does NOT state that the IRC, IECC, NEC, IPC, IMC, IFGC, IEBC, IPMC, or ISPSC editions have changed from the 2023-dated 'Design Criteria and Adopted Codes' sheet. Confirm the current IRC edition with Building Services (970-224-3211) before relying on this for a specific project, since the 2023 sheet predates the 2024 IBC/IFC adoption and may itself be stale for the other codes.; Local amendments to all adopted codes are codified in Timnath Municipal Code Chapter 18 (Building Regulations) via Municode, https://library.municode.com/co/timnath/codes/municipal_code?nodeId=CD_CH18BURE; specific amendment text should be read from Municode directly or from the adopting ordinances themselves.. Local amendments apply — see the Timnath overview page for the full list.
