An ALTA/ACSM land title survey is a survey that indicates the surveyor’s findings in great detail about the property boundaries; it also includes easements, encroachments, improvements and utilities within the property. ALTA surveys also provide information regarding zoning and flood zone designations. ALTA surveys are required by most lenders, title insurers, attorneys and buyers of commercial real estate. An ALTA survey may also be required if the buyer of a property desires survey coverage on his or her title policy. Example.
