If you're searching for homes for sale in Rocky Hill Borough, NJ, you're looking at Somerset County's smallest municipality — a 176-acre National Register Historic District anchored by Rockingham (Washington's official residence and headquarters in 1783 during the Continental Congress in Princeton), the Dutch Reformed Church (built 1856, Carpenter Gothic), full integration into the Montgomery Township School District (the only Somerset DFG J school district alongside Bernards), and direct walkable access to Montgomery Township and the Princeton corridor. With 743 residents (2020), estimated at 740 in 2023, Rocky Hill ranks 20th of 21 in Somerset County by population — making it one of the smallest municipalities in New Jersey.
The borough spans just 0.61 square miles total (0.61 land + 0.0039 water) — making Rocky Hill the smallest municipality in Somerset County by area (21st of 21) and 539th of 565 in NJ. Density of 1,216.4 per square mile (10th of 21 in Somerset) reflects the borough's compact historic village character. Elevation 108 ft. The borough is nestled within the heart of the Raritan Valley region and located alongside the course of the Millstone River.
Rocky Hill was officially incorporated as a borough on December 18, 1889. The borough is named after the Rocky Hill Ridge — the geographic feature that defines this corner of central New Jersey. The village's history traces to the 18th century — and one of the most significant moments in American history happened here. Rockingham, located in Rocky Hill, was George Washington's official residence and military headquarters from late August through November 1783 — while Washington attended the sessions of the Continental Congress meeting in Princeton at Nassau Hall. Washington wrote his famous "Farewell Orders to the Armies of the United States" at Rockingham on November 2, 1783 — one of the founding documents of the American military tradition. The borough's major growth period dates to the second quarter of the 19th century.
Government operates under the Borough form with a Borough Council legislative body. Mayor Robert Uhrik (D) currently serves a term ending December 31, 2026. The Municipal Clerk position is currently vacant. Despite Rocky Hill's small size, the borough maintains its own independent municipal government — one of New Jersey's most distinctive small-borough governance structures.
Education in Rocky Hill operates entirely through the Montgomery Township School District. Rocky Hill was historically a non-operating school district whose children attended Montgomery schools through a sending/receiving relationship; that relationship was subsequently formalized when Rocky Hill was incorporated into the Montgomery Township School District. Rocky Hill students now attend Montgomery's 5 schools (PreK-12) at 1014 Route 601 in Skillman, classified DFG J — the highest of New Jersey's eight District Factor Groups — with 4,611 students at 11.4:1 under Superintendent Mary E. McLoughlin. For grades 9-12, Rocky Hill students attend Montgomery High School (Cougars) at 1016 Route 601 — a 1992-93 National Blue Ribbon School of Excellence under Principal Heather Pino-Beattie, with 1,630 students at 13.6:1. Green and Gold colors. The Rocky Hill / Montgomery school relationship has been described as "a Rocky Hill address gets you Montgomery schools" — one of the most distinctive educational pipelines for a borough of Rocky Hill's size in New Jersey.

The borough's anchors include the Rocky Hill Historic District (176 acres, National Register July 8, 1982, encompassing Washington Street + Montgomery, Crescent, and Princeton Avenues, 145 buildings of which only 12 are non-contributing — sustained historic character without intrusion of modern structures or parking lots), Rockingham (Washington's 1783 headquarters), and the Dutch Reformed Church (built 1856, Carpenter Gothic, the village's most notable landmark). ZIP 08553; Area code 609.
Rocky Hill Borough's appeal rests on an extraordinary combination of strengths concentrated in just 0.61 square miles. First is Rockingham heritage: George Washington's official residence and military headquarters in 1783 (where he wrote his "Farewell Orders to the Armies of the United States" on November 2, 1783) is located in Rocky Hill — making the borough one of the most historically significant small communities in New Jersey. Second is the Montgomery Township School District access: Rocky Hill was historically a non-operating district sending students to Montgomery; that relationship has since been formalized through full integration. Rocky Hill addresses access Montgomery's comprehensive PreK-12 5-school district at DFG J (the highest of NJ's eight District Factor Groups) and Montgomery High School (Cougars) — a 1992-93 National Blue Ribbon School. Third is the 176-acre National Register Historic District: Rocky Hill's historic core (encompassing Washington Street + Montgomery, Crescent, and Princeton Avenues) was added to the National Register of Historic Places on July 8, 1982 for its significance in archeology, architecture, and commerce. The district encompasses 145 buildings of which only 12 are non-contributing — meaning the borough has sustained its historic character without intrusion of modern structures or parking lots. Fourth is Princeton corridor proximity: Rocky Hill sits immediately adjacent to Princeton and shares the same Princeton academic identity as the broader Princeton-edge corridor.
For buyers, this combination produces a market where median sale around $850K reflects the substantial premium of this rare combination — National Register historic district + Rockingham heritage + Montgomery DFG J school access + Princeton corridor proximity. Rocky Hill is the smallest municipality in Somerset County by area (0.61 sq mi) and 21st of 21 by population — making available inventory exceptionally limited.

Rockingham — the 18th-century house located in Rocky Hill — was George Washington's official residence and military headquarters from late August through November 1783, while Washington attended the sessions of the Continental Congress meeting at Nassau Hall in Princeton. Washington wrote his famous "Farewell Orders to the Armies of the United States" at Rockingham on November 2, 1783 — one of the founding documents of the American military tradition. Rockingham is operated as a state historic site and is one of central New Jersey's most historically significant Revolutionary War-era landmarks. The site provides direct access to Washington's final months as Commander-in-Chief of the Continental Army before resigning his commission to Congress in Annapolis, Maryland in December 1783.
The Rocky Hill Historic District encompasses 176 acres of the borough's historic core — Washington Street + Montgomery, Crescent, and Princeton Avenues. The district was added to the National Register of Historic Places on July 8, 1982 (NRHP reference #82003304) and to the New Jersey Register of Historic Places on January 14, 1982 (NJRHP #2580) for its significance in archeology, architecture, and commerce. The district encompasses 145 buildings of which only 12 are non-contributing — meaning the borough has sustained its historic character without intrusion of modern structures or parking lots. Architectural styles within the district include Vernacular, Colonial Revival, Queen Anne, and Carpenter Gothic from the 18th and 19th centuries.
The Dutch Reformed Church — built in 1856 in the Carpenter Gothic architectural style — is the most notable landmark in the village and sits at the heart of the Rocky Hill Historic District. The church anchors the borough's mid-19th-century architectural heritage and serves as the defining visual anchor of the historic village. Carpenter Gothic is a uniquely American adaptation of Gothic Revival architecture using wood and pattern-cut detailing — making the Rocky Hill Dutch Reformed Church one of New Jersey's most distinctive surviving examples of the style.
The borough is named after the Rocky Hill Ridge — the geographic ridge feature that defines this corner of central New Jersey. Rocky Hill is located alongside the course of the Millstone River, which flows northward through the broader Princeton-corridor landscape. The combination of ridge topography and riverside geography produces the distinctive small-village character that has defined Rocky Hill since the 18th century. The village sits within the heart of the Raritan Valley region of central New Jersey.

Portions of the original Montgomery Township (from which Rocky Hill was eventually formed) were also separated to form Princeton — meaning Rocky Hill, Montgomery, and Princeton share substantial historical and geographic kinship.
