This comprehensive code covers all construction, plumbing, mechanical, gas, and electrical requirements for one- and two-family homes and townhouses up to three stories.
The 2021 IRC includes several important changes, such as:
International Residential Code
Retaining wall lines must be placed on a physical wall or between multiple walls.
Two-family apartments must have a 1-hour fire separation, regardless of the presence of a fire-resistance-rated wall between them.
Emergency exits require a 36-inch wide clear path to the public way.
The design of storm shelters must be planned. Apartments require sprinklers, and habitable attics are restricted to half the floor below.
Updated wind speed maps now conform to IBC and ASCE 7 maps.
Deck design now considers snow load, tributary area, and mast height, as well as protection details.
IRC 2018 has added deck guards-specific requirements.
Component and cladding wind pressures in Table R301.2(2) have been updated for new wind speeds and shingle or gable roof profiles.
