IMPORTANT: the Town's live Building Division page (checked directly, current as of this extraction) 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 current IRC edition directly with Building Services (970-224-3211) before relying on this for a specific project, since the 2023 sheet predates the confirmed 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 — this page is a JavaScript-rendered CivicPlus codification app that could not be scraped directly in this session; specific amendment text should be pulled from Municode interactively or via the adopting ordinances themselves.. Local amendments apply — see the Timnath overview page for the full list.

Per SAFEbuilt Colorado's PV Submittal Requirements: 90 MPH 3-second gust wind speed, roof snow load 30 lbs/SF, and Seismic Design Category B, evaluated against the 2017 NEC, 2018 IRC, and 2018 IBC as cited in that document.
