Lexington Cut Its New Zoning by More Than Half. Here's What Actually Slowed Down.

An 1860s farmhouse sits at 89 Bedford Street, moved from the middle of its 1.6-acre lot to a spot near the sidewalk to make room for what's rising behind it: a three-story building with 30 new condominiums. The house itself is being split into two one-bedroom units. The land under both was assessed by the town at $1,256,000 for fiscal year 2025. The developer paid $7,250,000 for it, nearly six times that number.

That gap between assessed value and purchase price is the whole story of what's happened in Lexington over the past three years, and it's the piece that gets lost when a buyer scanning the market sees a single median price and assumes it describes one town. It doesn't. Lexington's rezoning under the state's MBTA Communities Act created two housing markets stacked on top of each other, and a political fight that was supposed to shrink one of them barely touched it.

The Vote That Made Headlines

Lexington was the first city or town in Massachusetts to adopt zoning under Section 3A of the MBTA Communities Act, passing an overlay in April 2023 that covered 227 acres across 12 districts, well beyond the roughly 50 acres the state required. Voters approved it with 63 percent support. Developers responded fast. Within about two years, applications were filed for nine or ten projects totaling close to 1,100 apartments and condominiums, concentrated along Bedford Street, Hartwell Avenue, Concord Avenue, and Militia Drive.

The scale surprised even the town's own planning department, and it surprised neighbors who watched a 1.6-acre lot on Bedford Street turn into a 30-unit condo building a few hundred feet from their driveways. Residents near Lois Lane raised concerns during planning board hearings about flooding and blind driveway sightlines. The pushback built into a citizen petition, and at a Special Town Meeting in March 2025, the town voted 164 to 9, with five abstentions, to cut the overlay from 227 acres down to 90 and tighten density and height limits.

"There is such a thing as too much growth."

That's Planning Board member Tina McBride, who helped lead the rollback effort. It's a reasonable sentence, and it's also not the end of the story, because the vote she helped pass didn't touch most of what had already been filed.

The Filing Deadline Nobody's Headline Mentioned

Before that March 2025 Town Meeting vote took effect, owners of 16 properties inside the original 227-acre district filed preliminary subdivision plans under the old, more permissive rules. Under Massachusetts zoning law, filing a preliminary subdivision plan freezes the zoning in effect on that parcel for eight years, regardless of what Town Meeting does afterward. Final subdivision applications for those 16 properties were due by August 2025, locking them into the pre-rollback bylaw through roughly 2033.

In plain terms: the vote that grabbed coverage narrowed where new multi-family construction can start today, but it did nothing to the projects that already had their paperwork in before the deadline. Those 16 parcels are still playing by 2023's rules.

Here's what that means on the ground right now, not as a hypothetical but as construction already underway or permitted:

None of these three depend on the 90-acre zone that survived the rollback. They were grandfathered in before the vote counted for anything.

Where the Word "Affordable" Stopped Doing Its Job

The MBTA Communities Act exists to add housing supply near transit, and Lexington's own 2022 comprehensive plan had flagged the town's home price increases as a real problem worth solving. So it's worth sitting with what the first wave of that supply is actually priced at. The cheapest unit at 89 Bedford Street listed at $1.2 million. That's the entry point for the town's flagship new-construction project under a law aimed at expanding access.

Compare that to the town's existing condo stock, which was trading at an average price closer to $526,000 in early 2026. The new construction isn't undercutting the old inventory. It's launching well above it. If you're a buyer who assumed "new zoning for multi-family housing" meant "a cheaper way into Lexington," the 89 Bedford Street price sheet says otherwise. It does include at least one unit designated affordable under the town's inclusionary program, with a lottery application deadline that passed in late April 2026, so by the time you're reading this that allocation has already been decided.

Single-family homes, meanwhile, carried a median sale price of $1,662,500 in early 2026, with homes going under agreement in about 16 days and buyers paying roughly 101.7 percent of asking price. That's the legacy market, still moving fast on its own terms. The new condos are a second, separate market layered on top of it, not a discount alternative underneath it.

What This Actually Means If You're Comparing Towns

If you're weighing Lexington against a neighboring town like Waltham, the single-family comparison still roughly holds shape. Waltham's median residential transaction over the past year lands around $848,030, well below Lexington's single-family numbers, which is what you'd expect from any portal search of the two towns side by side.

What doesn't match expectations is the condo picture. In most inner-ring towns, a condo is the more accessible entry point. In Lexington right now, brand-new condo inventory is priced at or above the town's own single-family entry tier, because it's competing on land scarcity and construction cost, not on offering a cheaper unit type. If your plan was to use a Lexington condo as a lower-cost way into the school district, the math from the first completed project doesn't support that plan. The existing, older condo stock at roughly $526,000 remains the actual lower-cost entry point, at least until the next wave of grandfathered construction reaches the market.

That next wave is coming. With 16 parcels locked into 2023 zoning through roughly 2033, and BXP's 312 units and SGL's 319 units still working through construction and permitting, Lexington's supply of new multi-family units is going to keep growing well past this year's political fight, whether or not the town cuts the zone further.

FAQ

Does the 2025 zoning rollback affect the projects already under construction? No. The 16 properties that filed preliminary subdivision plans before the March 2025 vote locked in the previous, larger zoning district for those specific parcels for eight years. Only new applications filed after the rollback are subject to the smaller 90-acre overlay.

Is the new construction part of Massachusetts' subsidized affordable housing stock? Some of it, in a limited way. The 89 Bedford Street project included at least one unit designated affordable under Lexington's inclusionary program, with an application deadline that passed in late April 2026. The bulk of the 30 units in that building, and the hundreds of units at 17 Hartwell Ave and on Militia Drive, are market-rate.

When does the grandfathered zoning expire? The eight-year freeze on the 16 parcels that filed before the March 2025 vote runs out around 2033. After that, any unbuilt parcels among them would need to comply with whatever zoning is in effect at that time.

If you're trying to figure out what a specific Lexington property, existing or new construction, is actually worth given where it sits relative to these zoning lines, that's the kind of question that benefits from someone who's spent time in mortgage underwriting and residential construction, not just portal browsing.
