Ask a longtime Allendale resident what kind of town this is, and the answer comes fast: quiet streets, big lots, almost nobody living in anything but a single-family house. The borough's own numbers back that up. As of 2022, 73.1 percent of Allendale's housing units were single-family detached homes, according to the borough's own amended land-use plan. That figure is close to the whole reason people move here, and close to the whole reason they pay what they pay to do it.
If you pulled Allendale's zoning map before this past February, though, you were looking at an outdated picture. On February 19, 2026, the Land Use Board and governing body approved an ordinance that expanded the borough's MFRO-3 overlay zone, the district built specifically to hold multifamily housing near the train station, and raised the maximum density allowed there to 26 units per acre. The amendment added a specific parcel, Block 702, Lot 15, into that overlay.
None of that shows up in a median home price. It shows up five and ten years from now in what gets built two blocks from the platform, and it matters to anyone comparing Allendale against other Bergen County towns on the assumption that "single-family character" is a fixed trait rather than a number that moves.
The 73 Percent Nobody Argues With
Start with what's actually true today. Allendale looks and functions like a classic low-density Bergen County borough: colonials and capes on generous lots, a downtown built around a working NJ Transit station rather than a strip mall, and almost no rental apartment stock scattered through residential streets. The 73.1 percent single-family figure is a real measurement from the borough's planning documents, not a marketing line, and it's the baseline against which everything else in this piece should be read.
That baseline is also exactly why the zoning change near the station is worth understanding rather than skimming past. A town this uniform doesn't add density by accident. When it happens, there's almost always a specific legal mechanism behind it, and in Allendale's case that mechanism has a name and a paper trail.
What Changed On February 19
New Jersey's Fair Housing Act requires every municipality to demonstrate a realistic opportunity for affordable housing production, and Allendale, like most Bergen County towns, satisfies part of that obligation through a court-approved Housing Element and Fair Share Plan. The MFRO-3 district, officially the Allendale Corporate Center Overlay Zone, exists inside that framework. It's the zone the borough designated years ago to concentrate higher-density, income-restricted housing near the train station and the Route 17 corridor rather than scattering it through single-family neighborhoods.
The February 19, 2026 ordinance didn't rewrite that strategy. It extended it, formally adding Block 702, Lot 15 to the overlay and setting the district's maximum density at 26 units per acre. That's a meaningful number in a town where the overwhelming majority of parcels are zoned for one house each. It is not, however, a borough-wide rezoning. The overlay stays geographically contained to the corridor around the station and the corporate campus off Route 17, not the residential streets that make up the rest of Allendale.
The takeaway for buyers isn't that Allendale is becoming a high-density town. It's that the density it does add is legally required to concentrate in one small, mapped area, and that area sits closer to downtown than most buyers assume.
The Building That Already Answered the Question
The overlay zone isn't a hypothetical. It already produced a real building. Hampshire Companies developed a 70-unit apartment community at 220 West Crescent Street, less than half a mile from downtown Allendale, designed by DMR Architects with a mix of one and two-bedroom units, six affordable units under the state program, and three units set aside for first responders. The building includes a clubroom, storage, a resident lounge, and an outdoor courtyard, and it sits close to Hampshire's other Allendale holding at 230 West Crescent Street, a formerly vacant industrial building the company brought back to full occupancy. Jersey Digs covered the announcement when it broke ground under a planned 2024 completion timeline.
That project, combined with the six-building flex campus known as the Allendale Corporate Center off Route 17, means the corridor between downtown and the highway already looks meaningfully different from the single-family streets a five-minute walk away. The February 2026 overlay expansion adds room for more of exactly this kind of project, not a different kind.
For context on why the station corridor is where this activity concentrates: Allendale's NJ Transit station sits directly in downtown, at Allendale, Park, and Myrtle avenues, and carries Main Line, Bergen County Line, and Port Jervis Line service into Hoboken. Transit-adjacent land is exactly where state fair-share housing law pushes municipalities to add density, because it's the location planners can defend as appropriate for it.
Why the Median Price You See Depends on Which Few Houses Sold
Here's the part that trips up out-of-town buyers doing comparison shopping online. Allendale is small enough that its monthly home-price median isn't really a market indicator in the way it would be in a larger town. It's closer to a snapshot of whichever handful of houses happened to close that month.
| Source & Window | Metric | Figure |
|---|---|---|
| Three months ending May 2026 | Median sale price | $800,000, down 7.3% year over year, on 11 closings in May |
| Three months ending May 2026 | Median price per square foot | $476, up 16.7% year over year |
| June 2026 | Median list price | $1.19 million, down 4% from the prior month |
| June 2026 | Median list price per square foot | $531 |
Look at the gap between the sold-price median and the asking-price median in the same general window. That's not a market swinging wildly in a few weeks. It's two different slices of a very thin dataset. Eleven sales is a small enough sample that one or two higher-end closings can pull the median up substantially, and one flat-fee brokerage's own market report even logged a headline year-over-year jump north of 40 percent for Allendale in early 2026, a figure that only makes sense as an artifact of a handful of transactions rather than an actual market shift.
The more stable signals in a market this size are sale-to-list ratio and days on market, tracked over several months rather than one. In February 2026, roughly half of Allendale's closings sold above list price at a 101 percent sale-to-list ratio, with homes taking a median of 66 days to close. Over the three months ending in May 2026, days on market had tightened to 51. Those figures move less between sources because they're less sensitive to which specific houses happened to trade in any single month.
What This Means If You're Comparing Allendale to Other Towns
If you're cross-shopping Allendale against Ridgewood, Wyckoff, or Ramsey based on a single median price pulled from a portal, you're comparing noise. Pull the trailing several months instead, and weigh sale-to-list ratio and time on market more heavily than the sale price alone.
If the character you're buying into is specifically Allendale's single-family, low-density feel, understand that character today is genuinely intact at 73.1 percent detached housing, but it's not static by accident. It's held in place by zoning that state law requires the borough to periodically revisit, and the overlay near the station is where that revisiting happens. A home a half mile from downtown sits in a different long-term context than a home on a residential street on the other side of town, even if both are single-family houses today.
And if you're specifically looking near downtown or the train station because you want walkability, know that you're also looking near the one corridor in Allendale where multifamily development has both already happened and been given more room to happen again.
A Few Straight Answers
Is Allendale becoming a high-density town? No. The February 2026 change expanded one existing overlay zone tied to the borough's state housing obligation. It did not rezone residential neighborhoods.
Does this affect resale value on existing single-family homes? There's no data yet showing a measurable effect, and it would be speculation to claim one. What's factual is that the overlay zone is geographically contained to the station and Route 17 corridor.
How do I find out if a specific listing sits inside the affected zone? The MFRO-3 overlay and the surrounding corporate center area are mapped by the borough. Ask your agent to check a specific address against the current zoning map before you assume anything about future density near it.
Understanding a market this small means reading past the headline number to the story behind it, and that's exactly the kind of local read Doreen Darquea brings to every Allendale conversation.
