WUI code and the wood-roof ban
Effective January 1, 2025, the Town of Jackson and Teton County adopted a Wildland-Urban Interface code (the 2024 ICC WUI Code) that covers all private land in the county. New construction and many alterations must meet ignition-resistant construction and defensible-space requirements, wood-shake and wood-shingle roofs are banned, and Class A roof coverings are effectively required. For mountain and forest-interface associations this is a real retrofit and reroof cost driver — and because Wyoming mandates no reserves, that cost is frequently unreserved. Confirm WUI compliance, defensible-space status, and any required retrofits before assuming the building is in compliance.
