2018 International Building Code (International Code Council Series)

2018 International Building Code (IBC) provides comprehensive building requirements for a wide range of structures, excluding detached one- and two-family dwellings and townhouses up to three stories. This essential code reference incorporates important updates to building safety, structural design, fire protection, occupancy requirements, wind and seismic provisions, and construction practices.

The 2018 IBC introduces numerous changes that affect architects, engineers, contractors, inspectors, code officials, and other construction professionals. From updated occupancy and fire-resistance provisions to revised structural and environmental design requirements, this edition helps users navigate current building code provisions and emerging construction practices.

Key Updates in the 2018 IBC

• Accessory storage spaces: Storage spaces of any size may be classified as part of the occupancy to which they are accessory.

• Medical gas systems: New code sections address medical gas systems.

• Higher education laboratories: New provisions address laboratory facilities in higher education settings.

• Fire walls: Restrictions clarify the use of fire walls for creating separate buildings and their role in determining allowable construction types, building area, and height.

• Elevator hoistways: Additional protection is required where elevator hoistway doors open into fire-resistance-rated corridors to address potential smoke intrusion.

• Business occupancy: The occupant load factor has been revised to one occupant per 150 square feet.

• Decks and balconies: Live-load requirements increase the deck live load to 1.5 times the live load of the area served.

• Fire wall lateral loads: The minimum lateral load that fire walls must resist is 5 pounds per square foot.

• Wind design: Updated wind-speed maps are included, including revised maps for Hawaii.

• Wind terminology: Ultimate design wind speeds are now referred to as basic design wind speeds.

• Seismic design: Site soil coefficients correspond to newer ground-motion attenuation equations.

• Wood truss inspection: Five-foot-tall wood trusses requiring permanent bracing are subject to periodic special inspection to verify installation of the required bracing.

• Mechanically laminated decking: A new alternative fastener schedule provides equivalent power-driven fasteners for the 20-penny nail.

• Wood construction: Updated provisions address solid-sawn lumber and other construction requirements.
