International Code Council, 06/13/2014. For one and two-family dwellings. Item #25619
From the Publisher:
The 2015 IRC® contains many important changes including:
Common walls separating townhouses must now be rated for 2 hours when an automatic fire sprinkler system is not installed.
Remodeling of an existing basement does not trigger the emergency escape and rescue opening requirements unless a new bedroom is created.
Ramps that do not serve the required egress door are now permitted to have a slope not greater than 1 unit vertical in 8 units horizontal.
Carbon monoxide alarms now require connection to the house wiring system with battery backup. A carbon monoxide alarm is required in bedrooms when there is a fuel-fired appliance in the bedroom or adjoining bathroom.
Revised lumber capacities have changed the span lengths for floor joists, ceiling joists and rafters in the prescriptive tables of the IRC.
New sections and tables provide prescriptive methods for posts, beams, joists and connections in deck construction.
The girder and header span tables of Chapter 5 have been moved into Chapter 6. Multi-ply and single header tables are combined. A new section describing rim board headers is added.
