Long Island is outside New York City, so the ACP-5 doesn’t apply. Instead, New York State rules call for an asbestos survey before renovation or demolition in older buildings, and many towns ask for it with the building permit. We do the survey, and if asbestos is found, we remove it and provide the documentation your town and contractor need.
