A boundary survey determines the property lines of a parcel of land described in a deed. It will also indicate the extent of any easements or encroachments and may show the limitations imposed on the property by state or local regulations.

A survey is strongly recommended before buying, subdividing, improving or building on land. Surveying the parcel before these activities ensures that the expense and frustration of defending a lawsuit, moving a building, or resolving a boundary dispute can be avoided.
