Lone Tree, Colorado has adopted: 2021 International Building Code (IBC), as amended — City of Lone Tree Design Criteria & Codes page; 2021 International Residential Code (IRC), as amended; 2021 International Fire Code (IFC); 2021 International Plumbing Code (IPC); 2021 International Mechanical Code (IMC); 2021 International Fuel Gas Code (IFGC); 2021 International Energy Conservation Code (IECC); 2023 National Electrical Code (NEC); 2017 ICC A117.1 Accessibility Code; Note on Chapter 18 (Building Regulations), Lone Tree Municipal Code: search-indexed content confirms the City has adopted the International Building Code, 2021 Edition, as amended, with a certified copy on file with the City Clerk; a local amendment adds Section 105.3.8 'Soils Test,' requiring a soils test prepared by a Colorado-registered professional engineer at building permit application, with an engineering geologist additionally required for hillside/geological-hazard/steep-slope sites at the Building Official's discretion. Full text of Chapter 18 could not be independently re-verified beyond this indexed excerpt because library.municode.com/co/lone_tree serves an Angular single-page app shell (empty of code text without JS rendering) and returned HTTP 403 to both a standard fetch and a full-browser-header curl retry — this is a partial-confidence caveat on the amendment-detail level only, not on the base code-edition list, which is independently confirmed on the City's own actively-maintained Design Criteria & Codes page.; HB22-1362 statewide energy floor (Colorado): as of 2026-07-06 (this review date), HB22-1362 requires that municipalities/counties updating their building code adopt an energy code achieving equivalent-or-better performance than the 2021 IECC + Model Electric and Solar Ready Code (effective window 7/1/2023-6/30/2026), stepping up to the Colorado Energy Code Board's Model Low Energy and Carbon Code (published 9/2/2025) as the new statewide minimum for any code update on or after 7/1/2026. Lone Tree's currently-published adopted energy code is the 2021 IECC (per its own Design Criteria & Codes page, most recent update not dated on-page) — this predates the 7/1/2026 Model Low Energy and Carbon Code trigger point and does not itself violate HB22-1362, since that stricter floor applies only when a jurisdiction next updates its code. Flagged honestly rather than assumed; confirm current status with the Building Division (720-390-5211) before relying on this for a 2026-cycle project, since Lone Tree could adopt updated codes at any time.. Local amendments apply — see the Lone Tree overview page for the full list.
