2024 International Residential Code (International Code Council Series) Paperback Edition

Description

The 2024 International Residential Code (IRC) serves as a comprehensive standard for the design, construction, and alteration of one- and two-family dwellings and townhouses up to three stories. Developed by the International Code Council (ICC), it integrates all building, plumbing, mechanical, fuel gas, energy conservation, and electrical requirements into a single, unified document.

Key Features of the 2024 IRC:

• Enhanced Formatting: The code has transitioned to a single-column text format with modernized font styles, improving readability. QR codes have replaced vertical margin sidebars and arrows to more accurately identify code changes. Additionally, shading for table headers and notes aids in quickly locating tables and relevant notes, and related content is now grouped together, with tables and figures placed immediately after the parent section.
• Significant Updates:
  • Fire Separation Distance: Imaginary lot lines are introduced to calculate fire separation distances when considering multiple dwellings on a single lot.
  • Shared Accessory Rooms: Two-family dwellings now have the option to include shared accessory rooms.
  • Electrical Requirements: The code now permits 10-amp circuits for certain lighting circuits, outlets, and exhaust systems.
  • Energy Storage Systems: New provisions have been added to address the requirements for energy storage systems, including protection measures for storage batteries in garages.
  • Loft Regulations: Requirements for sleeping lofts have been established for habitable attic-style lofts, and size limits have been set for tiny home-style lofts to meet specific exceptions.
  • Structural Reinforcement: Reinforcement of the floor below guards at mezzanines is now mandated.
  • Drain-Waste-Vent (DWV) System Testing: The final test of the DWV system may now be visual.
  • Air Exhaust Openings: Air exhaust openings are now permitted near operable windows and doors.
  • Refrigerant Options: A2L refrigerants have been added as an option for cooling equipment.
  • CPVC Pipe Joints: Solvent cement joints for CPVC pipes are now allowed both above and below ground.

These updates reflect the IRC’s commitment to enhancing safety, sustainability, and adaptability in residential construction. For professionals and stakeholders in the construction industry, the 2024 IRC serves as an essential reference to ensure compliance with the latest standards and best practices.
