New Jersey Boroughs: History, Governance, and Evolution
In the complex landscape of New Jersey's local administration, the borough (sometimes spelled boro) stands as a primary pillar of community organization. As one of five types and eleven forms of municipal government in the state, the borough represents a specific approach to local autonomy and administration.
While the majority of New Jersey residents live in townships, the borough is actually the most common form of local government among the state's 564 municipalities. As of 2023, there are 253 boroughs across the state, with Bergen County holding the highest concentration at 56.

Key Facts
- Prevalence: The borough is the most common municipal form in New Jersey, totaling 253 entities in 2023.
- Concentration: Bergen County has the most boroughs of any county in the state (56).
- Governance: Typically features a "weak mayor" system where the council holds most executive and legislative power.
- Historical Peak: A phenomenon known as "boroughitis" led to a surge of small borough creations in the late 19th century.
- First Borough: Elizabeth was the first, established by royal charter in 1740.
The Legislative Evolution of the Borough
The borough system has evolved through several key pieces of legislation, moving from exclusive royal and state charters to a standardized legal framework.
The Early Era and the 1878 Act
Initially, boroughs were created via special acts of the legislature. By 1875, only 17 existed, many of which were subdivisions of townships. However, a constitutional amendment in 1875 banned such special legislation, leading to the Borough Act of 1878.
This act allowed any township or portion thereof with a population under 5,000 and a land area of no more than four square miles to become an independent borough through a petition and referendum. This "self-executing" process triggered a period called boroughitis. This trend accelerated in 1894 when a law requiring townships to have a single school district prompted many communities to incorporate as boroughs to avoid paying for schools outside their immediate area.
Refining the System: 1897 and 1987
To curb the uncontrolled growth of small municipalities, the Borough Act of 1897 removed the self-executing feature. From that point forward, any new incorporation or change in borough size required legislative approval. This act also extended the mayor's term to two years.
More recently, the Borough Act of 1987 was implemented to modernize and streamline borough law. This legislation cleared away a century of contradictory rules and allowed boroughs to appoint a professional administrator to handle executive responsibilities.
Borough Government Structure
The traditional borough government is characterized by a weak mayor system. In this model, the elected council performs the bulk of the legislative and executive functions.
- The Mayor: Elected at-large in a partisan election. The mayor presides over council meetings but only votes to break a tie.
- The Council: Typically consists of six members elected at-large to staggered three-year terms.
- Exceptions: While most use at-large elections, Roselle and Roselle Park utilize ward structures, featuring five ward members and one at-large member.
This specific form of government is currently utilized by 39% of all municipalities in New Jersey.
