Yet even here, a familiar conflict has emerged, as reported by The Washington Post. Local officials are planning new apartment buildings, including units for lower-income households, and residents have mobilized to oppose several projects near historic neighborhoods. Yard signs and public letters now warn that new development could threaten the town’s character.
The dispute illustrates a tension common in cities across the country: many communities support the idea of more housing, but far fewer agree on where it should go.
New Jersey addressed that problem decades ago by changing who makes the decision.
Following a series of rulings by the New Jersey Supreme Court beginning in 1975, the state established what became known as the Mount Laurel doctrine. The principle is straightforward: every municipality must provide its “fair share” of housing opportunities for low- and moderate-income households. Municipalities periodically submit housing plans and can face litigation if they fail to comply.
The framework does not eliminate local control over land use. Cities still determine which sites to redevelop and how projects fit within existing neighborhoods. But the system does narrow the scope of debate. Instead of arguing about whether housing should be built at all, municipalities must decide how they will accommodate growth.
That shift matters.
Across much of the United States, housing shortages are often described as market failures or affordability crises. But many economists and planners point to a more basic constraint: local zoning rules frequently limit the supply of housing in high-demand regions. When each municipality can effectively veto new development, regional shortages are difficult to resolve.
New Jersey’s approach attempts to address that coordination problem by treating housing supply as a statewide responsibility rather than a purely local one.
The results have been uneven, and the policy tools remain contested. Some critics argue that the framework relies too heavily on mandates or litigation. Municipal officials often contend that smaller towns lack suitable land or infrastructure for significant growth.
Even so, the system has forced communities to grapple with redevelopment opportunities that might otherwise remain dormant.
In Princeton, earlier agreements under the state framework helped produce more than 1,000 housing units in recent years, much of it concentrated near commercial corridors that had struggled with vacancies. According to local officials, the area has since become a more active residential and retail district.
Other municipalities are pursuing similar strategies. Some have targeted aging office parks, retail centers or underused commercial sites for redevelopment. These locations often already have infrastructure and road access, making them more feasible for housing than undeveloped land on the metropolitan fringe.
The politics, however, remain difficult.
Residents often worry about traffic, neighborhood character or historic preservation. Local officials must balance those concerns with legal obligations imposed by the state. As the recent debates in Princeton demonstrate, even communities that broadly support housing goals can struggle when specific sites are proposed.
That tension is unlikely to disappear. But New Jersey’s experience offers a reminder that housing shortages are not simply questions of economics or design. They are also questions of governance.
When every city can block growth, regional housing shortages tend to persist. Systems like New Jersey’s attempt to solve that problem by requiring municipalities to plan for housing rather than avoid it.
Other states considering similar approaches will face their own tradeoffs. Yet the underlying challenge remains widely shared: deciding which level of government is responsible for ensuring that growing regions have room for new residents.
