WASHINGTON — Several states are adopting stronger building codes that require new construction to be more resilient to climate-related hazards — including flooding, wildfire, and extreme heat — as federal building code standards fail to keep pace with the rapidly changing risk environment.
California, Colorado, Oregon, and Florida have all enacted or proposed significant updates to their state building codes in 2025 and 2026, incorporating new requirements for wildfire-resistant construction, flood-resistant design, and energy-efficient building envelopes that reduce the risk of extreme heat events.
California's updated wildfire building code, which took effect in January 2026, requires new construction in high fire hazard severity zones to use Class A fire-rated roofing, ember-resistant vents, multi-pane windows, and non-combustible siding materials. The code also requires a minimum 5-foot non-combustible zone around the perimeter of the structure.
Florida's updated flood building code, which incorporates the latest FEMA flood maps and sea level rise projections, requires new construction in flood-prone areas to be elevated higher above the base flood elevation than previous codes required. The higher elevation requirements increase construction costs but significantly reduce the risk of flood damage over the life of the building.
The building code updates have significant implications for restoration contractors, who must be familiar with the applicable code requirements when performing reconstruction work after a disaster. Reconstruction that does not comply with current codes may be rejected by building inspectors, delaying the project and increasing costs.
