It is the property owners’ responsibility to determine where their property lines are; the city does not provide survey services to residents. However, if you have a mortgage on your property, it is possible that you have an improvement location certificate (ILC) among your closing papers. The ILC, while not a pinned survey, is a “birdseye” view of your property and shows existing structures and approximate distances from property lines. The Fremont County Assessor’s office maintains a Geographic Information System (GIS) database that shows the approximate location of property lines also. Remember that only a land survey conducted by a registered land surveyor in the State of Colorado can be fully relied upon to provide the accurate locations of your property lines, buildings and fences.
