A buyer touring Bridgewater earlier this year kept asking the same question: where's the new construction? Every home on the list was a 1960s or 70s colonial or split-level, freshly painted, maybe a finished basement, but nothing built this decade. Meanwhile a friend house-hunting twenty minutes away in Hillsborough was touring a golf-course community with move-in dates still eighteen months out, choosing between six different floor plans.
Both buyers were shopping the same price range. Hillsborough's median sale price came in at $707,450 in March 2026. Bridgewater's average home value sat near $725,000 over the same stretch. Close enough that a spreadsheet would call them the same market.
They are not the same market. One town is still building. The other one, structurally, can't.
The zoning code is the tell
Bridgewater's own municipal zoning ordinance prohibits flag lots in any zone district in the township, a rule that's been on the books since 1991 and was reaffirmed in a 2004 amendment. Flag lots are the odd-shaped, driveway-in-front parcels that towns often use to squeeze one more buildable lot out of an irregular piece of land. Banning them isn't a technicality. It closes off one of the few remaining ways a built-out suburb adds detached housing without a large parcel to work with.
The township's newest residential zoning move points the same direction. In March 2026, Bridgewater amended its RMDU-26 Multifamily Residential Zone, a designation created in 2022 specifically for one parcel, Block 400, Lot 7, to accommodate non-age-restricted multifamily rental housing with an affordable-housing component. That's the kind of parcel-specific overlay a town writes when it has run out of general-purpose land and has to legislate housing into existence one site at a time. It's also rental, not for-sale detached inventory, so it does nothing to loosen the market the buyer touring colonials was shopping in.
What Bridgewater has instead of new housing supply is retail reinvestment. Bridgewater Commons, the township's 1.2 million square foot mall and its economic anchor since 1988, is finishing a renovation that began in October 2025 and is expected to wrap in the second quarter of 2026. Anthropologie opened there in January, and the mall has added Kendra Scott, Alo Yoga, and Popeyes since new ownership took over in 2023. That's real investment, and it says something true about the town's health, but it's investment in commerce, not in the housing stock a buyer is shopping.
Hillsborough is still adding lots
A short drive southwest, Hillsborough tells a different story. Toll Brothers broke ground on Greens at Royce Brook in mid-2025, a community built in two collections adjacent to Royce Brook Golf Club. The Retreat Collection plans 87 homes and the Preserve Collection another 54, a total of 141 new single-family homes priced from roughly $1.28 million to $1.77 million. That's new supply landing at the top of the market, not the entry point, but it's supply the same way any new subdivision is: units that didn't exist a year ago now do, and every closed sale there is a transaction that never had to compete for an existing house.
That pipeline shows up in the numbers. Hillsborough's transaction volume was up 43% year-over-year as of March 2026, while days on market stretched to 24, up from 16 the year before. Read those two figures separately and they contradict each other. Read them together and they describe exactly what a town absorbing new supply looks like: more deals closing, but each individual listing facing less pressure to sell in a week, because buyers have somewhere else to look while they decide.
Same price, opposite mechanics
| Hillsborough | Bridgewater | |
|---|---|---|
| Price (spring 2026) | $707,450 median sale | ~$725,000 average value |
| Days on market | 24 (up from 16 the prior year) | ~22, classified a "very hot market" |
| Transaction volume | Up 43% year-over-year | Not expanding at a comparable rate |
| New construction pipeline | Active (Toll Brothers, Sharbell, D.R. Horton) | Zoning-constrained, largely rental/affordable overlays only |
| What's driving the price | Demand plus rising supply, still holding | Fixed detached stock, competition for what exists |
A town that's quietly adding inventory and a town that has already run out of land to add it on can post nearly identical median prices for completely different reasons. The number is the same. The explanation underneath it is not.
What this actually means if you're deciding between them
If you're shopping Bridgewater, don't wait for more inventory to show up. It's not going to. The zoning code has closed the mechanisms a town would normally use to add detached supply, so the pace you're seeing, homes moving in around three weeks with sellers getting 103% of list price as of May 2026, isn't a temporary squeeze. It's the ceiling of what the existing housing stock near Bridgewater Commons, Washington Valley Park, and Duke Island Park can support. Patience buys you nothing here except the risk of losing a house you liked to someone who moved faster.
If you're shopping Hillsborough, the slower pace and rising days on market can look like a softening market. It isn't one. Transaction volume climbing 43% in the same window means demand is strong enough to absorb everything the builders are adding, and the median price hasn't budged downward to compensate. What the slower pace actually buys you is room. Room to get an inspection done properly, room to negotiate on a listing that's sat a little longer than average, room to compare a resale colonial against something like Greens at Royce Brook before committing.
Neither of those buys you a lower price. They buy you a different kind of leverage, and knowing which kind you're working with changes how you should shop, not just where.
A new build and an established colonial aren't interchangeable, even at the same price. One buys unbuilt years of maintenance, a personalized floor plan, and, in Hillsborough's case, proximity to a golf course and to spots like Colonial Park Garden and Sourland Mountain Preserve. The other buys an established lot, mature landscaping, and a shorter walk to Bridgewater Commons or downtown Somerville. Whichever mechanism your target town runs on, the decision still comes down to what you actually want to live in, not just which number moved less this year.
A few direct questions
Does Bridgewater's fast pace mean prices there will keep climbing? A sale-to-list ratio measures competition for homes already on the market, not where prices are headed next. A 103% ratio tells you sellers currently have leverage. It doesn't forecast next year's median.
Is the Hillsborough new-construction pipeline going to bring prices down? Not based on what the data shows so far. Transaction volume rose 43% in the same window new homes were closing, which means the added supply is being absorbed by demand rather than sitting unsold. More inventory hasn't meant a lower median, at least not yet.
Could Bridgewater ever add a comparable pipeline? It would take a zoning change, not just market pressure. The current code specifically prohibits flag lots and channels new residential development into narrow, parcel-specific overlays like the RMDU-26 zone. That's a legislative constraint, and legislative constraints don't loosen on their own.
If you're weighing Hillsborough against Bridgewater, or any two Somerset County towns that look identical on paper, the median price is the least interesting number in the comparison. The mechanism behind it is what tells you how to shop, how much room you actually have to negotiate, and whether waiting helps you or costs you. That's the kind of read that comes from watching these towns closely, not from a single spreadsheet column.
