First things first
Mount Holly, once Northampton
Mount Holly is one of New Jersey's oldest townships. It was formed as Northampton in 1688, incorporated in 1798 as one of the state's original 104 townships, and officially renamed Mount Holly Township in 1931.
Over the years, land was split off from the original township to form neighboring towns, including Pemberton Township. Today Mount Holly Township covers just under 3 square miles, yet the 08060 Mount Holly ZIP code also serves neighboring Westampton and Eastampton. A Mount Holly mailing address does not always mean a Mount Holly tax bill, so we confirm the municipality and the block and lot on every home.
Neighborhoods
A small town with a big history
The heart of Mount Holly is the Mount Holly Historic District, which takes in about 260 acres of downtown and was added to the National Register of Historic Places in 1973.
- The historic downtown: The center of the county seat, with the historic county courthouse, the former county prison on High Street and historic homes.
- Along Rancocas Creek: Where a dam and mill race once powered the town's mills. The race still flows in its original course.
- Clermont: An unincorporated community inside Mount Holly Township.
Homes
What you will find
- Historic homes in and around the downtown historic district, some dating back centuries.
- Older single family homes in the neighborhoods around the historic center.
- Homes near the creek close to Rancocas Creek and the mill race, where the flood map deserves a close look.
Worth knowing: Two things matter most in Mount Holly. First, the creek. The North Branch of Rancocas Creek is tidal up to the dam in Mount Holly, and the National Weather Service noted that high tides added to flooding along the creek here in April 2007, so check the FEMA flood map for any home near the creek or the mill race. Second, local historic rules. The township's code creates a Historic Preservation Commission and two local historic districts, the High Street Historic District and the Mount Holly Municipal Historic District, and exterior work or demolition there generally needs a certificate of appropriateness. We pull the flood and historic details for every address.
