2012 International Residential Code (Looseleaf)
2012 International Residential Code for One- and Two-Family Dwellings (Looseleaf) is a comprehensive code that compiles all building, plumbing, mechanical, fuel gas and electrical requirements for one- and two-family dwellings and townhouses up to three stories. Changes for this edition include:
- New Seismic Design Category (SDC) map that results in smaller SDC E regions.
- New wind maps delineate areas requiring design to resist wind forces and identify windborne debris regions.
- A new table for minimum fire separation distance for dwellings equipped throughout with an approved automatic sprinkler system.
- Doors between the garage and dwelling unit now require self-closing devices.
- Wireless smoke alarms are now specifically permitted for satisfying the interconnection requirements in both new and existing dwelling units.
- The provisions for roof connections to resist wind uplift forces have been updated and simplified. A new table provides prescriptive values for both low and high slope roofs in wind exposure categories B and C.
- When a parapet is not installed, openings and penetrations of the roof are no longer permitted within 4 feet of the separating wall between townhouse dwelling units.
- Now includes prescriptive provisions for the construction of isolated masonry pier foundations supporting raised floor systems.
- Installation of œ-inch gypsum board or equivalent is now required on the underside of floor assemblies of cold-formed steel framing, I-joists, open web trusses and similar light-frame members.
- IRC Wall Bracing provisions have been completely reorganized to place each topic in a separate section and improve the flow of information.
- New simplified wall bracing provisions offer an alternative method of bracing in low seismic regions with basic wind speeds of 90 mph and exposure category A or B.
