I have a home that has 4 feet to the boundary line. A door on the side is elevated roughly 1.5-2 feet. I’m thinking about putting a sidewalk in from front to back and building a structure that would be a landing at the door level and ramped to the front and back. This would allow access of anything wheeled to go from the front to the back. In addition I would have a privacy fence built on the property line.

So my question. Would I need to anchor the small deck structure to the sidewalk? Also with the fence, should I build footings for the posts, or would that sidewalk hold it in place? Appreciate the feedback.
