 2018 International Building Code® (IBC®) Soft Cover

This code applies to all buildings except detached one- and two-family dwellings and townhouses up to three stories.

The 2018 IBC contains many important changes such as:

• Accessory storage spaces of any size are now permitted to be classified as part of the occupancy to which they are accessory.

• New code sections have been introduced addressing medical gas systems and higher education laboratories.

• Use of fire walls to create separate buildings is now limited to only the determination of permissible types of construction
   based on allowable building area and height.

• Where an elevator hoistway door opens into a fire-resistance-rated corridor, the opening must be protected in a manner to
    address smoke intrusion into the hoistway.        

• The occupant load factor for business uses has been revised to one occupant per 150 square feet.

• Live loads on decks and balconies increase the deck live load to one and one-half times the live load of the area served.

• The minimum lateral load that fire walls are required to resist is five pounds per square foot.

• Wind speed maps updated, including maps for the state of Hawaii. Terminology describing wind speeds has changed again
   with ultimate design wind speeds now called basic design wind speeds.

• Site soil coefficients now correspond to the newest generation of ground motion attenuation equations (seismic values).

• Five-foot tall wood trusses requiring permanent bracing must have a periodic special inspection to verify that the required bracing has been installed.

• New alternative fastener schedule for construction of mechanically laminated decking is added giving equivalent power-driven
   fasteners for the 20-penny nail.    

• Solid sawn lumber header and girder spans for the exterior bearing walls reduce span lengths to allow #2 Southern Pine design values.
