A survey made for the purpose of supplying a title company and lender with survey and location data necessary for the issuing of title and/or mortgage insurance. A detailed map is required to meet “ALTA” specifications. The acronym "ALTA" stands for American Land Title Association. Specifications of this type of Survey include (but are not limited to) determining property lines, location of improvements, identifying all easements, utilities and other conditions affecting the property. ALTA surveys are very comprehensive surveys, sometimes taking weeks to complete and are typically the most costly. Any ALTA Land Survey must meet the "Minimum Standard Detail Requirements for ALTA/ACSM Land Title Surveys" as adopted by the American Land Title Association, the American Congress on Surveying and Mapping, and the National Society of Professional Surveyors. The Alta Survey is most often performed on commercial properties.
