2021 International Wildland-Urban Interface Code – IWUIC-2021

The 2021 International Wildland-Urban Interface Code® (IWUIC) establishes requirements for construction, land use, and vegetation management in wildfire-prone areas. Designed to reduce fire risk to buildings and communities, the code integrates prescriptive and performance-based strategies informed by real-world fire data and global mitigation research.

Highlights:

• Defines construction standards, defensible space, and vegetation management to limit wildfire spread
• Offers both prescriptive requirements and performance-based compliance options
• Regulates ignition-resistant construction, fire-resistive roofs, walls, and access infrastructure for responders
• Fully coordinated with 2021 I-Codes (IBC, IFC, IRC) for integrated hazard regulation
• Developed with input from AIA, IAFC, NASFM, and NAHB to reflect safety, design, and construction priorities

Who It’s For:
Planners, fire marshals, building officials, architects, and developers managing wildfire risk and land development in wildland-urban interface zones.
