Pro Tips on Building a Code-Compliant Deck By Rob Robillard. There are approximately 40 million decks in the United States, and only half of those are code-compliant. Deck safety is a real problem. Every year we hear about decks that collapse under the weight of people or snow load. Improperly built decks can be dangerous Appendix B provides an acceptable method of designing a deck, at the owner's option. It is mainly based on the 2012 American Wood Council's standard, Design for Code Acceptance 6 (DCA-6) - Prescriptive Residential Wood Deck Construction Guide. Note that DCA-6 is based on the 2012 International Residential Code acceptable depending on whether the deck is free standing or attached (see Figure 6 & 7). Consult with Plans review personal at 919‐772‐4688 to select a method that meets code and will work best for your project. 2 Figure 3 How deep and how large must the footings under support posts be

In such a case, a freestanding deck makes sense. But there are other reasons we might choose not to tie a deck to a house. Take, for example, a garrison colonial, where the second-floor framing cantilevers a foot or two past the wall below. Those overhangs are almost never designed to support the additional weight of a deck. We have in fact. While the building code may be the same for deck attachment whether the deck is 2 feet or 10 feet above grade, the consequences of deck failure are much greater for the elevated deck. Where deck ledger attachments are questionable, the best approach is to build a freestanding deck , supported on its own piers, with angle bracing to prevent racking Where you may think twice about building an elevated deck with shallow footings, the safety risk from the frost-heaving that shallow footings may experience on a grade-level deck is very low. The main code provision for footings that applies to freestanding decks (R403.1.4) calls for a minimum footing depth of 12 inches below undisturbed ground. decks, only half are code compliant - leaving 20 million decks that need to be rebuilt or retrofitted. To help design and building professionals build code-compliant, safe decks, Simpson Strong-Tie® has created this Deck Framing Connection Guide.
