Middlesex and Middlesex County
Middlesex is associated with Middlesex County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Middlesex by land and water
The Census records 0.02 square miles of water within Middlesex, or 0.6% of its total area. It is 3.6 percentage points lower than the 4.2% recorded for Middlesex County. This is geographic context; waterfront status and usable land must be checked at the parcel.
