What kind of survey do I need? There are many kinds of boundary surveys. They are classified by their intended purpose and the level of detail required to complete the survey. The most basic is a typical boundary survey. It will show the least amount of detail and is usually performed for general information or for a simple conveyance. Another type is a mortgage survey, which is often required by a lending institution when financing or refinancing a property. The level of detail can vary, but typically these surveys will show the major features of a property, such as a house, well and septic. There is also the NYSAPLS survey performed in New York State. This type of survey is done using the standards adopted by the New York State Association of Professional Land Surveyors. This will typically show major and minor improvements and observed surface utilities. The most complex type of boundary survey is most often the ALTA/ACSM Land Title Survey. This survey can vary in complexity and detail, but includes title certificate review, and can include such things as subsurface encumbrances, wetlands, elevation relief, offsite servitude, and more. The purpose of these types of surveys is to assist in clarifying a title so that a title policy may be written. These are most often prepared for commercial properties.
