Applying the International Residential Code (IRC)

This course delivers a deep dive into the structural and safety provisions of the 2021 International Residential Code (IRC), focusing on real-world application for single-family homes, duplexes, and townhouses. Engineers will explore load paths, framing systems, fire resistance, egress, and glazing requirements—translating code language into actionable design decisions. With updates from the UDC and side-by-side examples, participants will be prepared for both current enforcement and future code adoption.

Upcoming dates coming soon!

Take course number RA01819 when it’s offered next.

What You Will Learn:

Gain practical, code-based strategies to design, evaluate and build residential structures in compliance with the 2021 IRC. This course equips engineers with the tools to streamline permitting, avoid costly delays, and ensure structural and life safety compliance.

Who Should Attend:

  • Architects and structural and civil engineers designing residential buildings.
  • Plan reviewers, code officials, construction managers, and inspectors seeking practical code application.
