Footings must be a minimum of 36" in depth and 12" in width

Hand rails/guards must be a minimum 36" in height

Open guardrails on decks more than 30" above grade or a floor below shall have members spaced

Site Plan Requirements:

What is a site plan for a deck?
A site plan is a drawing that shows your property boundaries, the house, and other major structures, it also shows the set back distances between main structures and property lines to the deck construction. A simple deck plan only needs to be a sketch that includes these measurements.
