You can determine residential property lines by using specific measurements, geographical features or GPS coordinates usually specified in the deed of a particular property. Local government offices, including an assessors office or a city planning department, often have specific information on the property lines located within that municipality.
In many cases, homeowner documents include a detailed description of a property's extent, including maps that outline the plot from a bird's-eye view. Other documents might include a computer rendering of the property lines as they relate to certain physical features. Some cities or towns offer an online interactive map for the public to use in order to find property lines in certain areas. A residential property developer might have buried small pieces of metal at the edges of the property, making it easier to identify the property lines with the use of a metal detector.
For conclusive results, a homeowner can hire a certified land surveyor to mark the parcel's property lines based on the specifications outlined in the deed. A developer often creates new property lines when parcelling out an area of land and building a new neighborhood or development. These new property lines must comply with a municipality's zoning laws, which might regulate the sizes of lots.
