This video, from Steven L. Smith of King of the House Home Inspection in Bellingham,WA, explains the safety benefits of properly anchoring a deck, balcony or porch ledger board to the exterior wall of a building. The content is intended, primarily, for those people who wish to upgrade/retro-fit an existing structure.
1. This information DOES NOT apply to decks and similar structures at manufactured or mobile homes.
2. Lag screws/bolting has been the traditional means of properly attaching a ledger board for many years. However, some builders and jurisdictions now prefer, and encourage, "through-bolting" -- where bolts with accompanying nuts extend through the ledger board and the building's framing.
