Surveys are not required, but they are recommended. It is the responsibility of the property owner erecting the fence to know where their property boundaries are. A dispute as to the location of a property line is a civil matter between abutting land owners. If a survey is not submitted with a permit application, a clear and accurate site plan must be submitted indicating lot line locations which can be verified in the field, the location of structures on the property, and the location of the proposed fence.
