New Jersey is on the cusp of a housing boom. Not a speculative one — a mandated one. And while the headlines focus on the politics of who has to build what, very few people are talking about the second-order effect: what tens of thousands of new housing units do to the neighborhood strip centers that serve them.
I'll walk you through the mechanics, because once you understand how this works, you can't unsee it.
Start with the setup
New Jersey has a housing supply problem. The state is among the most densely populated in the country, land is scarce, entitlements are slow, and we've underbuilt for decades. The result is predictable: New Jersey now carries some of the highest home prices in the nation. Buyers are getting priced out, renters are stretched, and demand keeps outrunning supply.
Into that imbalance steps a piece of legal machinery that's been running for fifty years.
Enter the Mount Laurel Doctrine
In 1975, the New Jersey Supreme Court decided S. Burlington County NAACP v. Mount Laurel — a ruling so consequential it spawned an entire body of law now known simply as the Mount Laurel Doctrine. The principle: every municipality has a constitutional obligation to provide a realistic opportunity for its "fair share" of the region's affordable housing. The Fair Housing Act of 1985 built the administrative scaffolding around it.
The doctrine has teeth again. In March 2024, Governor Murphy signed P.L. 2024, c.2 (the A4/S50 law), establishing a new framework for the Fourth Round of obligations covering 2025 through 2035. It streamlines the process, codifies how each town's number is calculated, and — critically — makes the obligations much harder to dodge. The state's affordable housing shortage is estimated north of 200,000 units, and the new round calls for tens of thousands more to be built or zoned for.
In other words: towns now have hard quotas, a real clock, and far less room to stall.
The problem: affordable housing doesn't pencil
Here's where it gets interesting, because the mandate runs straight into financial reality.
Affordable units come with income-based rent caps. Depending on the income tier, those capped rents can land at a fraction of market rate — in some cases less than a third of what the same unit would command at market.
Now run the developer's math. Operating expenses on a multifamily project routinely run around 35% of revenue before debt service — taxes, insurance, maintenance, management, reserves. Those costs don't shrink just because the rent is capped. So when a developer is forced to take a deep haircut on rent while carrying the same expense load, the project simply doesn't pencil. No rational builder develops a 100% affordable project on conventional financing. The numbers don't work.
"Capped rents, uncapped costs. That's the math that makes a 100% affordable project impossible — and it's the reason the fix looks the way it does."
The fix: the 80/20 trade and PILOT incentives
So municipalities are increasingly forced into a compromise to get anything built at all. Two tools do the heavy lifting:
The unit mix. Rather than demand standalone affordable projects, towns approve developments that blend market-rate and affordable units — frequently around an 80/20 split. The 80% market-rate units subsidize the 20% affordable ones, and the blended project becomes financeable.
Tax incentives. On top of that, towns layer in incentives like PILOT programs — Payment In Lieu Of Taxes — which give developers a predictable, often-reduced tax obligation for a set term instead of conventional property taxes. That improves the return enough to get shovels in the ground.
Put those together and you get a two-pronged solution: the state relieves its strained overall housing supply through the 80% market-rate units, while the town satisfies its affordable quota through the 20%. Everyone's box gets checked.
The friction is real — and it doesn't matter
None of this happens quietly. Affordable housing still carries a stigma among long-standing residents, and proposals routinely draw fierce local opposition — concerns about congestion, strain on public services, overcrowded schools, and the catch-all "character of the neighborhood." NIMBYism is alive and well.
But here's the thing: the towns don't have a choice. Some have tried to litigate their way out, and most efforts have failed. More than twenty municipalities banded together to challenge the new law — and the challenge went nowhere; even the U.S. Supreme Court declined to take it up.
Look at South Brunswick, one of our core markets. The township spent roughly nine years litigating its affordable housing obligations — and ultimately settled, committing to build around 1,500 affordable units over the next decade. Under the 80/20 logic, satisfying that affordable number means approving on the order of 7,500 total new units. That's close to a 50% increase over the township's current housing supply. After nearly a decade of fighting, the outcome was more building, not less.
That story is playing out, in different sizes, across the state.
What it means for the market
When you force that much new supply into a market over a defined period, you guarantee two things: population growth, and — more importantly — density growth. More rooftops, packed closer together.
For existing residential landlords, that's a mixed bag. A meaningful increase in supply can put downward pressure on rents and prices over time — basic economics.
For builders, it's an enormous opportunity, and we've positioned for it directly. We recognized this trend and stepped outside our usual niche to lead an ambitious ground-up project: 239 units in Piscataway — 200 multifamily and 39 single-family homes, 40 of them affordable. See the 1700 Washington project → That's us putting the thesis to work on the development side.
But the silent winners? Neighborhood retail landlords.
"More housing units, more population, more density. That's more everyday people who need the everyday services that live in a neighborhood strip center."
More rooftops, sticky demand
Think about what every one of those new units actually contains: people. People who need a haircut, a manicure, a dentist, a pediatrician, a daycare, a slice of pizza, a gym, a dry cleaner, a convenience store, a place to grab dinner on a Tuesday. Everyday services delivered by the everyday businesses that fill neighborhood strip centers.
That demand is sticky and Amazon-proof. You can't stream a haircut. No algorithm fills a cavity. The more households you pack into a trade area, the more foot traffic and recurring local demand flow to the service tenants in the strip center down the road — and the more pricing power and occupancy stability the landlord enjoys.
Residential supply growth is, structurally, a tailwind for commercial retail. The state is about to manufacture that tailwind on a massive scale, by legal mandate, whether the neighborhoods like it or not.
The takeaway
The housing boom is coming because it has to. The supply is going up because the courts say so. And every new unit is another customer for the neighborhood retail that serves it.
If you've been waiting for a reason to get into neighborhood retail, the mechanics are pointing in one direction. Now is the best time to get in — before the rooftops, and the demand they bring, fully arrive.
