4. Compliance Verification Initials:

  • All posts are to be supported on appropriate concrete pad / block supported on flat level compacted surfaces, or if on top of deck, load transferred down to appropriate deck posts and supports.
  • Posts shall support the full width of beams, and shall have lateral bracing if more than 24” to underside of joists (knee bracing, mechanical bracket, or similar; toe-nailing is not adequate).
  • Ledger boards (where applicable) must be secured to the house with lag bolts (GRK or similar), 1 bolt every 16” or 2 bolts ever 32”. Rafters are to be supported at the ledger with proper hangers and proper hanger nails or hanger screws (no deck screws).
  • All beam and rafter spans are required to comply with the requirements of the NBC span tables, or similar reference documentation such as the Canadian Wood Council. The construction of a built-up beam is complex and includes very specific requirements for allowable joints in the plies, and nailing requirements.
  • Rafters shall bear fully on the beam(s) which will require a proper ‘bird-mouth’ notch (while leaving proper amount of material to top edge) or shims, and are to be secured to the beam(s) with mechanical ties / clips for wind uplift conditions.
  • Deck screws are not permitted to connect structural members together, they are only good for holding down deck boards.
  • Piles are required to support deck roofs when they are secured to houses that have below grade foundations.
