Ask people what they love about Mendham and you tend to hear two answers at once. Some talk about the village: a walkable Main Street lined with buildings, some of which have stood for more than two centuries. Others talk about the countryside: winding roads, old hamlets, and wooded properties a few minutes from that same crossroads. Both answers are right, because "Mendham" is really two municipalities, the Borough and the Township, that share a name, a history, and a high school.
Here is a closer look at the Mendhams.
A Little History
Mendham Township is the older of the two. It was formed on March 29, 1749, from parts of Hanover, Morris, and Roxbury Townships, and it was incorporated in 1798 as one of New Jersey's original 104 townships. Water, forests, and minerals drew early settlers. By 1748 the area around Ralston had iron forges, sawmills, and a gristmill along the North Branch of the Raritan River.
The Borough came later, and for a very practical reason. In 1906, residents of the village center wanted sidewalks and streetlights. Families in the more rural parts of the township, including Brookside and Ralston, felt the cost was too high for their areas. The village separated and was incorporated as Mendham Borough on May 15, 1906.
Even the name has more than one story. It may come from Mendham in Suffolk, England, or from a Native American word, mendom, often translated as "raspberry."
The Village at the Center
The heart of the Borough is the Mendham Historic District, listed on the National Register of Historic Places in 1985. It covers about 153 acres along Main Street and includes 140 contributing buildings that tell the story of the village from the 1750s into the early twentieth century.
Two landmarks anchor it. The Phoenix House, built around 1800, became William Phoenix's inn in 1806 and was donated to the Borough in 1938. It has served as the municipal building ever since. Down the street, the Black Horse traces its roots to 1742, and the Borough describes it as New Jersey's oldest continually operating restaurant.
Since 1999, the Borough has had a historic preservation ordinance meant to protect the district's character. Buyers who love that character should know it comes with a review process for certain exterior changes.
Hamlets, Hills, and Trails
Beyond the village, Mendham Township spreads across roughly eighteen square miles of rolling, wooded country. The historic hamlets of Brookside and Ralston are both listed on the National Register. After the Civil War, wealthy families built country homes here, much as they did in Bernardsville's Mountain Colony next door. One of the best-known estates, Wendover, sits on the southern slope of Bernardsville Mountain and is now home to Roxiticus Golf Club.
The land also sits at the top of two watersheds. An unnamed pond in the Borough is the source of the Passaic River, and the North Branch of the Raritan also begins there.
For time outside, the county's Patriots' Path runs through the area. India Brook Park has a trail to Buttermilk Falls, and the Schiff Nature Preserve offers wooded hiking close to home.
Schools and Getting Around
Each Mendham runs its own Pre-K–8 district: the Mendham Borough Schools and the Mendham Township Public Schools. For grades 9–12, students from both Mendhams, along with Chester Borough and Chester Township, attend West Morris Mendham High School, part of the West Morris Regional High School District. As always, families should confirm current programs directly with the districts.
No interstate passes through either Mendham, which is part of the appeal. County Route 510 is the main local artery, and Interstates 287, 78, and 80 are within reach. Rail commuters typically drive to the Morristown station for NJ Transit's Midtown Direct service into Manhattan.
What Buyers Should Know
If Mendham is on your list, a few practical notes:
- Borough or Township? They are separate towns with separate school districts, tax rates, and land-use rules. A Mendham mailing address alone doesn't tell you which one you're in.
- Historic district considerations. In the Borough's historic district, ask early about review requirements before planning exterior work.
- Highlands rules. Both Mendhams fall within the New Jersey Highlands Region, where state planning rules can affect development and expansion. Your attorney and the town can explain how they apply to a specific property.
- Utilities vary. Some homes are on public systems while many rural properties rely on a private well and septic system. Plan your inspections around what the property actually has.
The Takeaway
Mendham offers something rare: a real village, with history you can walk past every day, surrounded by countryside that still feels like countryside. Whether you picture yourself near the Main Street crossroads or down a quiet road near Brookside, the Mendhams reward people who value character and a little breathing room.
