Footings

  • Footings must be at least 12″ below the undisturbed soil surface.
  • Size and thickness of the footings are determined by the tributary area that they support, and the load bearing value of the soil.
  • Where decks are attached to a frost protected structure, the footings must extend below the frost line, be erected on solid rock, or use other approved methods of frost protection.

Posts

  • Posts must be centered on the footings.
  • Maximum height of the posts are determined by the size and species of the post and the tributary area.
  • Lateral restraint must be provided where the posts bear on concrete footings.
