International Residential Code 2012

This edition of the International Residential Code (IRC) provides the comprehensive building-safety provisions governing one- and two-family dwellings and townhouses, including structural design, foundations, framing, fireplaces, energy efficiency, mechanical, plumbing, and electrical systems. The 2012 IRC consolidates model-code requirements into a single reference used by contractors, inspectors, and exam candidates to ensure residential construction practices align with nationally recognized standards.
