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.
