Re: States that require a boundary survey. Well, in the spirit of the question, MA requires a survey for the creation of any new property lines. Subdivisions that require an approval from a planning board, of course, need plans and current surveys.
This is the most common type of survey, and if you have ever purchased or sold a property before, chances are you had a simple survey performed. Most counties and states require at least this type of survey to be performed whenever a property changes hands. A simple survey usually costs between $300 and $500.
