2027 International Zoning Code®

Provides a structured and consistent approach for land use for construction within a jurisdiction. This code supports health, safety, property protection, and welfare through orderly land development, land-use controls, and regulation of the design, location, use, and occupancy of buildings and structures.

The International Codes® (I-Codes®), developed by the International Code Council, establish safeguards to protect public health, safety and welfare within the built environment. This 2027 edition of the International Zoning Code® provides a comprehensive, coordinated set of model regulations for the design, construction and maintenance of the built environment. Structured for technical precision, the IZC delivers enforceable requirements aligned with nationally and internationally recognized standards. The I-Codes serve as a reliable regulatory framework adoptable and adaptable to innovative and evolving technologies, materials and methodologies.

The IZC provides the following:

• Enforceable prescriptive and performance-based provisions organized by scope and occupancy
• Harmonized technical provisions coordinated with companion I-Code® titles
• Referenced standards developed by recognized consensus bodies
• Clearly defined scope, applicability, terminology and compliance pathways
