Ask most people what happens to a town's home values when its largest taxpayer announces it's leaving, and you'll get the same answer: prices soften, buyers get cautious, the market cools while everyone waits to see what fills the gap. That's the story anyone would expect for Berkeley Heights right now. Nokia Bell Labs, the company that has occupied 600 Mountain Avenue since 1942 and helped invent the transistor and the Unix operating system there, announced back in December 2023 that it's relocating to a new research tower at the HELIX innovation campus in New Brunswick, with the move expected to wrap by 2028.
Here's what the data actually shows. As of the update posted at the end of June 2026, the average Berkeley Heights home value stood at $983,263, up 5.5 percent over the past year. Zip code 07922 posted a median sale price of $943,000 over the three months ending in June 2026, up 3.8 percent from the same period the year before, with homes averaging just 13 days on the market. In August 2026 alone, a four-bedroom on Hastings Road closed at $1,281,000 against a $979,000 list price, 31 percent over ask. A house on Emerson Lane listed at $475,000 sold for $750,000, 58 percent over list. Whatever effect the Bell Labs announcement was supposed to have on this market, it hasn't shown up in the sales data.
That gap between the assumption and the numbers is worth understanding before you compare Berkeley Heights to any other commuter town. The real story isn't that the market shrugged off the news. It's that the process determining what actually happens to that 200-acre site is still unresolved, and it just became a lot more concrete.
What actually happened on Mountain Avenue
Nokia's exit was announced at a splashy press conference at the New Brunswick Performing Arts Center in December 2023, with Governor Phil Murphy and Nokia leadership on hand. The new facility, a 360,000-square-foot lab and office tower being built by New Brunswick Development Corporation and SJP Properties, will house Nokia Bell Labs' work in quantum computing, photonics, and 6G research. Roughly 1,000 employees are expected to relocate.
For two years after that, the Murray Hill campus sat in a kind of planning limbo. The township ran community surveys and visioning sessions. Officials talked about preserving open space and courting new commercial tenants. Nothing was legally binding.
That changed on February 3, 2026, when a resolution appeared on the Berkeley Heights Township Council's agenda authorizing the Planning Board to conduct a formal Preliminary Investigation into whether the Nokia site qualifies as an "Area in Need of Redevelopment" under New Jersey's Local Redevelopment and Housing Law. That's not a symbolic gesture. It's the first legal step required before any formal redevelopment plan can move forward. The same meeting included a separate ordinance raising the maximum permitted residential building height to 2.5 stories in several zoning districts, a second, independent signal that density pressure is building across town, not just on the Nokia parcel.
The investigation the township ordered has a defined process:
- The Planning Board maps the boundaries of the study area.
- Board consultants apply the specific criteria New Jersey law sets out for a redevelopment designation.
- A public hearing takes place before any recommendation goes back to the full Council.
- The Council votes on whether to formally designate the site, which then opens the door to a negotiated redevelopment plan.
Because the resolution studies the property as a non-condemnation area, eminent domain isn't part of this process. That detail matters to residents worried about a forced sale, but it doesn't change the underlying fact: the town is now actively deciding what this land becomes, and that decision touches every property tax bill in Berkeley Heights.
Why the tax question outranks the price question
Berkeley Heights' own township government describes Nokia Bell as currently the largest taxpayer in town. The campus is the last remaining large tract of undeveloped or underutilized land in the township, and roughly 400 feet of its frontage along Mountain Avenue actually sits across the municipal line in New Providence, which is why both towns' mayors have been coordinating on the response since the announcement first broke.
The site is currently zoned office and research use only. Any buyer who wants to build housing, retail, or a mixed-use project there has to get zoning changes approved by both the Township Council and the Planning Board first. That gives Berkeley Heights real leverage, not just over what gets built, but over how much tax revenue the town actually collects once it's built. If the township negotiates a PILOT, a payment in lieu of taxes agreement, with whatever developer eventually takes the site, the town can secure substantially more revenue than a standard tax assessment would generate. If it doesn't, or if negotiations drag, the town absorbs the loss of its single biggest ratable while waiting for a replacement that may take years to materialize.
State officials have been blunt about what's really at stake. New Jersey Economic Development Authority CEO Tim Sullivan framed it as a ratables question for the community, tied directly to replacing revenue the town stands to lose. Governor Murphy has publicly said he's a bull on repurposing the site, calling it "a gem of a location" with enormous upside. Optimism from Trenton doesn't settle the timeline, though. The New Brunswick facility isn't slated to open until 2028, and the redevelopment investigation in Berkeley Heights is only in its earliest procedural stage as of this year.
Downtown didn't wait for an answer
Here's the part that gets lost when people focus only on the Nokia site: Berkeley Heights has been adding housing stock for years, independent of whatever happens on Mountain Avenue.
The bigger driver has been the township's court-mandated affordable housing obligation, negotiated down to 389 units after a round of builder lawsuits under the state's Mount Laurel doctrine. That obligation, combined with private investment, is reshaping the town's core. The former Connell Corporate Park, a 185-acre office campus off Interstate 78 that once held 1.5 million square feet of office space, is being redeveloped with more than 325 residential units and roughly 190,000 square feet of new dining, retail, and entertainment space. Closer to the train station, Elite Properties of Watchung has nearly finished Berkeley Crossing II, a 53-unit mixed-use building on Springfield Avenue, and recently signed two retail tenants there: a fitness club and a computer school for kids. Elite also built a smaller 10-unit building nearer the station and named a pocket park there after Vito Mondelli, the former owner of the land who ran a farm stand on it. The broader downtown redevelopment includes a separate green space, Peppertown Park, named for the peppers once grown by the Italian immigrant farmers who first settled the township.
Taken together, these projects are expected to add more than 725 new households to the downtown core, on top of the units rising at the former Connell campus, for a total approaching 1,000 new housing units townwide. As of that January 2024 reporting, one-bedroom rentals in the downtown building boom were listed starting around $2,500 a month, with for-sale townhouses priced separately. Mayor Angie Devanney has called it the biggest change to hit Berkeley Heights in a generation, in a town that's mostly single-family homes with roughly 13,000 residents.
That's the second half of the hidden mechanism. Berkeley Heights isn't a town holding its breath waiting to see what replaces one employer. It's a town already absorbing significant new housing supply from multiple directions at once, with the Nokia site sitting as the largest remaining unknown in an otherwise active building cycle.
What this means if you're comparing towns
If you're weighing Berkeley Heights against another commuter market, the Nokia site is worth a specific question to your agent or the township, not a reason to hesitate. Ask where the redevelopment investigation stands, whether a PILOT agreement is under discussion, and what the Planning Board's study area boundaries look like once they're published. None of that will move a closing date this year. All of it will shape property tax trends over the next several years, especially if the eventual use skews toward more market-rate housing rather than a mix of commercial ratables.
In the meantime, treat the current data for what it is: thin inventory, fast sales, and steady price growth in a town that's been absorbing new housing at a meaningful pace since well before anyone knew Nokia was leaving. The uncertainty sitting on Mountain Avenue is real. It just hasn't been the thing moving prices.
A few direct questions
Does the Nokia Bell Labs move affect my property taxes right now? Not yet. Nokia remains in place through at least 2028, and no redevelopment plan or PILOT agreement has been approved. The February 2026 resolution only authorizes a study.
When will Berkeley Heights know what replaces the campus? There's no firm timeline. The Planning Board's investigation has to run its course, including a public hearing, before the Council can even vote on a redevelopment designation. Given the site's size and the number of parties involved, including New Providence, this is likely a multi-year process.
Should I wait to buy in Berkeley Heights until this is resolved? Current sales data doesn't suggest the market is pricing in a delay. Homes are selling in under two weeks on average with several recent sales well over asking. Waiting on a process with no set end date means competing in the same thin-inventory market later, likely at a higher price.
