A new code requirement for decks

摘要

Associate editor Chris Ermides replies: No and yes. The section from the International Residential Code to which you're referring (R502.2.2) says that decks have to be designed for both vertical and lateral loads. That part has been on the books for years and is meant to keep the deck from pulling away from the house. But the 2009 IRC does have a new provision that gets specific about what's required to support a lateral load.rnThe new code section (R502.2.2.3) states that "hold-down tension devices" be installed in at least two locations per deck. Whether you are attaching a deck that's 3 ft. long or 30 ft. long, you will be required to use the hold-down tension devices in two locations.
