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.

2021 International Zoning Code – IZC-2021
The 2021 International Zoning Code® (IZC) provides a streamlined, enforceable model for regulating land use, building placement, and development density. Designed to simplify zoning administration in both urban and rural areas, the IZC aligns with the full suite of 2021 I-Codes to support coordinated regulatory practices.
Highlights:
- Offers a clear, structured framework for use types, setbacks, lot coverage, signage, and parking
- Fully compatible with 2021 I-Codes (e.g., IBC, IRC, IMC) for unified code enforcement
- Facilitates zoning administration through defined processes for permits, appeals, variances, and nonconforming uses
- Supports local flexibility while maintaining consistency and legal enforceability
- Developed through ICC’s consensus process with input from planners, builders, and public officials
Who It’s For:
Municipal planners, zoning administrators, code enforcement officers, and policymakers managing land use and development in communities of all sizes.
