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.
