International Residential Code (IRC) for One- and Two-Family Dwellings

The International Residential Code (IRC) provides comprehensive requirements for the design and construction of one- and two-family dwellings and townhouses up to three stories. This essential building code resource brings together requirements for building, plumbing, mechanical, fuel gas, and electrical systems in a single reference.

The IRC includes important provisions covering structural safety, fire protection, residential construction, seismic design, emergency escape and rescue openings, smoke alarms, framing, and high-wind construction. Its detailed requirements help architects, builders, contractors, code officials, engineers, and other construction professionals understand and apply residential building standards.
