Hangers at ledger shall provide the required uplift resistance. Cantilevered deck joists more than 5 feet above grade shall be attached to the beam with hurricane clips or straps to resist wind uplift. 7. Deck posts are to be mechanically anchored to the caissons and to the beam above. Use post caps, strapping, or brackets designed for this purpose. 8. The framing system shall be inspected prior to concealment. All joists and beams shall have 1% inches of full bearing. Call for a rough frame inspection prior to decking for all decks less than 5 feet above grade. 9. Each basement is required to have at least one emergency escape and rescue opening directly to an exterior yard. If an existing sleeping room or basement has its only emergency escape/rescue window or door located below the proposed new deck, the deck shall not cover or obstruct the required window well opening. A grate or cover is permitted provided that it is openable from the inside without the use of a key, or any special knowledge or force more than required for the window. A ladder may be required if the deck increases the effective depth of the window well to more than 44 inches. 10. Glazing closer than 5 feet from stairs and landings shall comply with IRC Section R308; safety glazing may be required. 11. A solid, level landing that is at least as wide as the steps, but not less than 36" x 36" shall be provided at the bottom of the steps. Landings may slope a maximum of¼ inch per foot. Complying handrails are required when there are 4 or more risers. See attached "Building Guide" for stair requirements. 12. Composite decking material shall have a valid evaluation report, and installation shall comply with manufacturer's requirements. 13.
