Warren County mayors respond to N.J. affordable housing guide for 2025
Municipalities in New Jersey now know exactly how many new affordable housing units they are expected to authorize over the next decade, according to a recent report.
Roughly 2,800 units are required to be built or rehabilitated by 2035 in Warren County. (See the numbers for each Warren County town below.)
The data provided by the New Jersey Department of Community Affairs shows the responsibility for affordable housing units in every municipality in the county will increase in 2025. Greenwich Township tops the list with the largest responsibility (360 units).
Two affordable housing projects are in the pipeline. Greenwich Dumont Urban Renewal Associates LLC has promised 66 affordable units along Dumont Road in a project called The Willows at Greenwich, part of Ingerman Family Communities; and a project called Furhman could bring 64 units to the township, a clerk said..
White Township (322 units) and Allamuchy Township (281) have second and third highest responsibilities. The most densely populated town in Warren County, Phillipsburg, has a responsibility to provide 75 affordable units, according to the report. The town currently has the largest share of affordable housing units in the county.
Mayor Randy Piazza said he has no doubt the town will meet its responsibilities.
The calculations include two types of affordable housing obligations — “present need” and “prospective need.” Prospective need refers to creating new affordable housing, while present need means renovating existing affordable housing that has been deemed “substandard.” The numbers below are shown to represent present to prospective need.
The state also looked at the median income in each town and assessed the open space, existing homes and other factors to calculate municipalities’ responsibility.
The numbers below do not mean municipalities need to build affordable housing themselves but, municipalities must zone for builders to propose construction of the housing.
Warren County
Allamuchy Township, from zero to 281
Alpha Borough, from four to 58
Belvidere, from 20 to 131
Blairstown Township, from zero to 65
Franklin Township, from 32 to 95
Frelinghuysen Township, from zero to 156
Greenwich Township, from zero to 360
Hackettstown, from 87 to 105
Hardwick Township, from zero to 29
Harmony Township, from four to 71
Hope Township, from zero to 31
Independence Township, from six to 65
Knowlton Township, from four to 32
Liberty Township, from 25 to 35
Lopatcong Township, from zero to 87
Mansfield Township, from seven to 418
Oxford Township, from zero to 54
Phillipsburg, from 21 to 75
Pohatcong Township, from zero to 65
Washington Borough, from zero to 27
Washington Township, from 31 to 181
White Township, from 100 to 322
The guidelines follow a new law (S50) signed by Gov. Phil Murphy in March, which standardizes obligations for municipalities throughout the state to build more housing units. It also gives towns more protection from lawsuits that aim to stop affordable housing from being built.
The requirements are part of the state’s fourth round of affordable housing obligations under the Mount Laurel Doctrine, which refers to a series of landmark state Supreme Court decisions that outlawed exclusionary zoning practices and required all towns in New Jersey to provide their fair share of the region’s affordable housing.
The state Department of Community Affairs released non-binding calculations Friday on the number of affordable homes in the state’s 564 municipalities.
The obligations are recalculated every 10 years in cycles known as rounds. Each municipality’s obligations are calculated by looking at various factors, including job growth, existing affordable housing and the growth of low- and moderate-income households.
Urban municipalities’ obligations often include higher “present need” numbers because they’ve historically produced more affordable housing than suburban municipalities, the Fair Share Housing Center said.
The state Department of Community Affairs also announced it is launching NJ Housing Opportunities for Municipal Equity and Success, called NJHOMES, early next year. The initiative provides for financial resources, technical assistance and other tools to help municipalities develop affordable housing in their communities.
Municipalities are expected to have plans submitted to the state by Jan. 31.
After this, Pohatcong Township will be out of developable land and sewer allotments, said Mayor David Slack. The township now has three affordable housing projects in the pipeline. Larken Living Apartments is expected to open its affordable units before the end of the year, he said.
Frelinghuysen Township contributes fewer than a dozen affordable housing units to the county’s total, consisting mostly of long term care and group homes. Developers haven’t shown interest in developing apartments in the area, said Mayor Keith Ramos. The township is down for planning 156 more units before 2035.
“I don’t know that 283 is an achievable number, but I would need more info before making that judgment,” Ramos said. “It’s clear that no matter what the numbers the goal post is not set at zero.”

Blacksmith Triangle, the site of a former gas station at the corner of North Olden and Lawrence avenues in Trenton, has taken on a new life as the city’s latest green space.
New Jersey Conservation Foundation (NJ Conservation), in partnership with the City of Trenton and other environmental and community organizations, worked to transform the site into a forested park addition over the last two years. Improvements included site clearing and grading, seeding, new sidewalks, bollards, a brick-paved entry plaza, and 14 honey locust trees. The project’s completion was celebrated in May.
The City remediated Blacksmith Triangle years ago to clean up the contamination left behind from its former use as a gas station. But until recently it remained covered with concrete and asphalt and was often used as a de facto parking lot. In 2024, NJ Conservation received a grant from the Licensed Site Remediation Professionals Association Foundation to plant trees on the site, which spurred conversations with Trenton officials about turning the lot into a forested plaza and gateway to George Page Park and the Assunpink Greenway. Construction began in December 2025, thanks to a significant financial contribution from the City of Trenton and additional funding secured by NJ Conservation from private donors.
With this new green space, project leaders aim to increase shade for city residents, who are experiencing disproportionate impacts of climate change. Trenton neighborhoods are dealing with the ‘heat island effect’ that causes higher ambient temperatures in urban areas than in suburban and rural areas.
“Excessive heat is deadly in our communities, and this work will help future generations of Trentonians cope with the rising temperatures that will come with our new climate realities,” said Jay Watson, NJ Conservation’s Senior Fellow for Conservation Justice. “New Jersey Conservation Foundation is proud to do this green infrastructure work in our capital city.”
At a grand opening celebration for Blacksmith Triangle last month, Paul Harris, Trenton’s Director of Recreation, Natural Resources, and Culture, said the City is excited about the lot’s transformation, highlighting the partnership that made the project possible.
“Our goal is to green as much of the town as we can, but in order to do that successfully, we need to bring on partners,” said Harris.
The revitalization of Blacksmith Triangle is part of a larger greening effort throughout the city. NJ Conservation and its partners — City of Trenton, Isles, the New Jersey Tree Foundation, the Watershed Institute, and the Outdoor Equity Alliance — are working to build a greener, more equitable New Jersey through the Trees for Trenton program. Thanks to a grant from the New Jersey Department of Environmental Protection, 1,000 shade trees are being planted throughout Trenton, creating a healthier environment for residents and visitors.
Trees for Trenton was announced in 2023 at an Arbor Day celebration when the first trees were planted at Mulberry Street Park. More than 900 trees have been planted throughout the city since then.
