Do Decks Really Need to  Meet Code Requirements? 

 

Because decks may look relatively simple to build, many people do not realize that they are structures that need to be designed to meet minimum standards and resist certain stresses. Like a house, or any other building, a deck must be designed to support the weight of people and objects placed on it, as well as lateral and uplift loads that can act on the deck as a result of occupant movement, wind or seismic activity. The 2012 / 2015 versions of both the IBC and IRC contain language outlining the general design requirements of structures. This excerpt from the 2012 / 2015 IRC (Section R301.1) represents a summary of the intent of both codes:  “The construction of buildings and structures in accordance with the provisions of this code shall result in a system that provides a complete load path that meets all requirements for the transfer of all loads from their point of origin through the load-resisting elements to the foundation.” The concept of a complete or continuous load path refers to a series of solid connections and structural members within the deck that transfer load to the ground or adjacent supporting structure (commonly a building). This same principle is applied to the design of all types of wood-frame buildings. This continuous load path is created by using a system of structural connectors and fasteners to connect the wood members together

Make sure to work with a Professional Contractor that understands the design and function of your Deck.
