After the Court Decision: What 108 Stockton Street Means for Princeton

On February 13, 2026, Judge Robert Lougy of the Mercer County Superior Court approved Princeton's Fourth Round housing plan, clearing a major hurdle for the 108 Stockton Street development.

It's no surprise that the development has drawn the attention of many Princeton residents. This proposed mixed-income project stands just short of construction, awaiting final board site approval after nearly three years in planning. The former 4.8-acre Tennent-Roberts-Whiteley campus, owned by the Princeton Theological Seminary, is under contract for sale to Herring Properties for redevelopment. In total, 238 new housing units are to be built: 190 designed as market-rate, expected to rent from $3,000 to $4,000 per month depending on size, and 48 designed as affordable. Unlike market-rate apartments, affordable units are priced based on a household's income relative to the area median income (AMI), making them available to low- to moderate-income households. The development would both expand Princeton's housing supply and help the municipality meet the state's affordable housing requirement.

Although town officials have been open about their support, the development's objectors remain skeptical of both the process and the project itself.

Sean Wilentz, a history professor at Princeton and co-founder of Defend Historic Princeton, an organization that opposes the development, said, "This is not just any town, any municipality, just like this is not just any university." He isn't alone. A walk along Stockton Street reveals rows of houses with "Defend Historic Princeton" signs out front.

The Tennent-Roberts campus, once part of Princeton Theological Seminary, now sits vacant behind fencing. Although the Princeton Theological Seminary itself continues to operate, its chapel, library, and academic buildings still open. As residents and tourists pass the Tennent Robert campus, they are met by long green barricades blocking the grassy landscape and fallen trees along Stockton Street.

Residents raise other concerns too: construction traffic on Route 206 during commute hours, density once the complex is occupied, and environmental risks from heavy vehicles working the site.

At the June 8, 2026 council meeting, one resident raised her concern over the nearby Spruce Street development, being built "10 feet away from her backyard."

Residents are justified in raising these concerns. But there is a broader policy context at work.

When town officials, and Councilwoman Mia Sacks in particular, supported the development, they did not dismiss residents' concerns about traffic, density, and environment. Instead, they weighed them against the towns Fourth Round affordable housing obligation

The Fourth Round obligation is Princeton's affordable housing plan for the decade (2025–2035). For years, Princeton, like many New Jersey municipalities, used exclusionary zoning that limited apartments, duplexes, and smaller homes, indirectly pricing out low- and middle-income families. New Jersey's 1975 Mount Laurel Doctrine set out to correct this, requiring each municipality to meet successive rounds of affordable housing obligations. Princeton is now in the fourth round, and Stockton Street is central to meeting it.

The municipality wrote, in its summary of the February 10, 2026 court decision led by Judge Thomas C. Miller: "Both Judge Miller and Special Adjudicator Cofone specifically found that the 108 Stockton Street inclusionary project is set to deliver 48 affordable homes in a highly suitable location that is proximate to transit, services, and employment opportunities."

On paper, the project checks the boxes: it helps satisfy the state mandate while redeveloping a long-vacant parcel. But opponents are careful to say their objection isn't to affordable housing itself. "Our concerns were not about whether Princeton should meet its affordable housing responsibilities, but about how those responsibilities are implemented," said Jo Butler of the Princeton Coalition for Responsible Development.

Their argument centers on scale. Defend Historic Princeton contends the complex would be the densest development in any residentially zoned area in Princeton, with buildings reaching as high as 70 feet among two- and three-story homes, some dating to the 1840s. Opponents say that in 2023 they proposed an alternative: a fully affordable development of roughly 50 units, more than the 48 in the current plan, at a scale they argue better fits the neighborhood. The town did not adopt it.

The likely reason lies in how Mount Laurel is meant to work. The doctrine calls for low- and moderate-income housing to be integrated throughout a town, not concentrated in one place, in order to avoid economic segregation. A fully affordable complex would make the state's unit requirement easier to meet, but it would cut against that mixed-income principle. As Princeton tries to move from exclusionary zoning toward neighborhoods that hold both affordable and market-rate homes, a project combining the two fits the goal, which is part of why the township moved forward with the original plan.

Supporters make a broader case as well. A development like 108 Stockton Street, they argue, opens Princeton to families long priced out, unable to afford even an apartment in town. Mayor Mark Freda acknowledged the cost himself: "If I were to buy a house here now, I couldn't afford to buy a house." Access to Princeton's schools, its walkable downtown, and its location between New York and Philadelphia, supporters contend, has been out of reach for these families. The affordable units are designed with that in mind, single-family friendly with one- to three-bedroom capacity.

The Daily Princetonian framed the fight as a choice: "to defend or expand." The legal challenges have largely run their course, but the matter isn't settled. Final site-plan approval is still pending, and opponents are weighing further action.

What's left is the harder question underneath the lawsuits: How does a town meet an obligation it can't avoid without losing the character its residents value? Both the obligation and residents' concerns are real and valid. Through Stockton Street, Princeton is working out the answer.

The next council meeting is July 13 at 7 p.m. Stockton Street is not on the agenda, but the public comment period is open to any resident on any subject. What happens on Stockton Street will shape what happens next across Princeton.

Correction, July 12: An earlier version of this piece said the theological seminary sits behind fencing. In fact, only the Tennent-Roberts-Whiteley parcel, the portion being redeveloped, is fenced. The seminary itself remains open and operating. This piece also pointed readers to the July 13 council meeting in a way that implied Stockton Street would be discussed there. It is not on that agenda, though the public comment period is open to any subject.
