3.1 International Residential Code

The IRC applies to one- and two-family dwellings and townhomes not more than three stories above grade plane, with certain limitations for high wind, high seismic, and high snow regions. The IRC requirements that are related to connectors and fasteners in coastal areas are summarized in Table 1.

Although Table 1 refers to selected requirements of the 2018 IRC and notes changes from the 2015 and 2012 editions, subsequent editions should include comparable requirements.
