Nope. They are both done by a surveyor. A plot plan shows the lender where your house is located on the land. It shows if there are any zoning violations. Older homes were built before there was zoning. They are too close to the side yard or the front yard. They are "grandfathered". Plot plans in my area cost around $250.00
Surveys are much more expensive. They run into thousands of dollars depending upon the size of the lot. Surveys are done for the purpose of "pinning" the boundaries. If it is a rectangular lot then the four boundaries have pins installed. I have a 76.6 acre parcel of land for sale. It has never been surveyed. Potential buyers are made aware that I have no idea where the boundaries are located. I have the assessor's map which is not to be used for conveyance purposes.
Surveys and plot plans are similar but very different.
