Grand County Planning Commission recommends 2021 building code and state Wildfire Resiliency Code

The Grand County Planning Commission on March 11, 2026 recommended that the Board of County Commissioners adopt the 2021 International Building Code and the state-mandated Wildfire Resiliency Code after a staff presentation outlining local amendments and implementation timing.

County staffer Kristen Manguso and Robert Wilson presented updates to the 2021 code, saying local amendments will correct previous errors and keep insulation requirements consistent with the county’s existing 2015 standard. Manguso told commissioners that because the Wildfire Resiliency Code is state law "the county has no local discretion; compliance is required to ensure residents can maintain their homeowners' insurance."

Commissioner Brad White confirmed that Grand Fire and the county will use the locally produced Community Wildfire Protection Plan map rather than the state's map and will submit the local map to the state for approval. Staff described the code’s focus on "building hardening," including fire-resistant siding, decking and windows. To avoid requiring full exterior upgrades on existing homes, presenters said additions generally should remain under 500 square feet.

Staff said the county is targeting July 1, 2026 for implementation to allow for public education. Manguso also warned that county and fire department capacity to enforce the new standards is limited; she said insurance coverage requirements may operate as the principal compliance mechanism in practice.

Two members of the public spoke during the discussion. Ken Wright expressed support for the effort, while Daniela Gosselova said she would like more public comment opportunities before the Board of County Commissioners and urged county enforcement rather than relying on insurance.

Lynn Adams moved to recommend approval of both codes; Chris Murphy seconded the motion and it passed unanimously. The Planning Commission’s recommendation will be transmitted to the Board of County Commissioners for final action.

The commission’s discussion and vote on the codes concluded the first major agenda item; staff noted next steps will include submitting the local wildfire map to the state and preparing public education materials ahead of the July 1, 2026 target implementation date.
