These drawings answer different questions. Confusing them can leave a permit package or a plan purchase missing information that was never part of the original scope.
What the floor plan communicates
A floor plan shows the building’s room arrangement, dimensions, openings, and related information at a given level. It helps evaluate how the home functions. Even a detailed floor plan does not by itself locate the house relative to property boundaries.
What the site plan communicates
A site plan relates the proposed building and relevant site features to the property. Its required content depends on the project and reviewing authority. It may need to address placement and other site information that is absent from a catalog house set.
Where the survey fits
A survey provides property information used by the project team; it should not be treated as interchangeable with a proposed site plan. A drawing of existing conditions and a drawing of proposed improvements serve different purposes. Confirm whether the available records are sufficient for the requested work.
Coordinate the documents together
A change to the house footprint should be reflected in the site work as applicable. Full Set Designs can help identify which documents are available and scope site-planning coordination alongside the building plans. Confirm the required deliverables before submission.
A common question
Does buying a floor plan include a site plan for my land?
Only if the package explicitly includes that service. A project-specific site plan needs property information, so check the written scope rather than assuming it comes with a catalog download.
