This is a specialized survey frequently required by lending institutions on large commercial or multi-family residential properties. It adheres to a specific set of requirements jointly established by the American Land Title Association (ALTA) and the American Congress on Surveying and Mapping (ACSM). Generally, in addition to the boundary of the subject property, all of the improvements located on a site will be measured, identified and shown on the survey, together with all applicable easements and setback requirements established by provided documents.
