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.
Pay by State. Surveyors in California earned the most in 2011, reporting an average annual salary of $82,370. Nevada ranked second at $73,180 per year, followed by Alaska at $73,100, Massachusetts at $70,920 and Delaware at $70,360.
