Lexington Voted To Slow Its Housing Boom. Some Corridors Never Got The Memo.

"Lexington is changing. It's all happening very quickly." That's how Alan Levine, who has lived on Reed Street since the 1980s, described his town to the Boston Globe earlier this year, pointing out parcel after parcel slated for redevelopment on a drive through the center he's known for four decades.

If you're comparing Lexington to Concord, Waltham, or Acton right now, the number you've probably already seen is the median sale price. Typical home values in town reached $1,626,351 in June 2026, up 2.3 percent over the past year, with homes moving to pending in about 15 days. That number is real, but it's not the story that matters most if you're about to buy a house near Bedford Street, Hartwell Avenue, Concord Avenue, or Militia Drive. The story that matters is a zoning fight the town thought it had settled, and a legal mechanism that means it isn't settled at all in a handful of specific places.

The vote that was supposed to fix this

In spring 2023, Lexington became one of the first Massachusetts towns to comply with the state's MBTA Communities Act, a law requiring transit-served municipalities to allow multifamily housing by right in at least part of town. Town Meeting didn't do the minimum. Officials rezoned 227 acres, including parts of Lexington Center and aging office parks near Route 128, for buildings up to six stories with few restrictions on density. The plan passed with more than 60 percent support, and it came with a projection: Boston.com's report on the reversal notes that officials estimated 400 to 800 new units over a decade.

That estimate did not hold up.

Governor Maura Healey sent her personal congratulations after the original vote. Bill McKibben, a former Lexington resident, praised the town in a piece for The New Yorker. Then the applications started landing on real streets, and the reaction on the ground looked different than the reaction at Town Meeting.

The rollback, and what it didn't touch

The flashpoint was 89 Bedford Street, a 30-unit condo project that is on track to be the first development permitted under the new zoning to finish construction. Neighbors raised concerns about repeat basement flooding and tight sightlines at the site's driveways, and because the project met the letter of the new rules, there wasn't much room to negotiate. That fight fed a broader campaign to scale the zoning back, and on March 17, 2025, a special Town Meeting voted 164 to 9, with five abstentions, to shrink the MBTA Communities district from 227 acres down to roughly 90 and tighten height and density limits.

If you're only tracking headlines, that vote reads like Lexington hit the brakes. Two of the pipeline's largest projects show why that isn't quite right. Town of Lexington filings show that both 131 Hartwell Avenue and 475 Bedford Street had their definitive subdivision plans finalized in the months after that March vote, in June and July 2025, and each was awarded a zoning freeze on August 13, 2025. A zoning freeze locks a parcel into the zoning rules tied to its plan, and for these two sites that means the larger, more permissive 2023 and 2024 overlay rules, not the shrunken district Town Meeting had just approved. The freeze holds through August 2033.

That's not a footnote. It means the political rollback and the actual development envelope on specific parcels are two different things, and a buyer needs to know which one applies to a given address before assuming a neighborhood's zoning risk is behind it.

Where the old rules still apply

Four corridors carry most of Lexington's active pipeline, and the projects on each one are at different points in the freeze-versus-rollback split:

• Hartwell Avenue. At 17 Hartwell Avenue, BXP's 312-unit project had its subdivision finalized on March 12, 2025, five days before the rollback vote, and broke ground that July after the joint venture acquired the 5.25-acre site for $21.84 million with a $98.7 million construction loan from Northwestern Mutual. A few lots over, 131 Hartwell Avenue didn't finalize until June 2025, three months after the vote, yet JLB Realty's 290-unit project still secured an August 2025 freeze under the same 2024 Village High-Rise Overlay rules.
• Bedford Street. The 89 Bedford Street condo project is the one that triggered the neighborhood backlash. A few blocks away, 475 Bedford Street, the site of a shuttered Boston Sports Club, cleared Planning Board approval in April 2026 for Fieldside at Lexington, a 150-unit, three-building project from Pulte Homes, protected by the same August 2025 freeze under the 2023 Multi-Family Overlay rules.
• Concord Avenue and Militia Drive. Developers have filed for hundreds more units along both corridors, according to town development records cited in Hoodline's coverage of the zoning fallout.
• Lexington Center. A four-story mixed-use building with more than 50 homes is planned near Belfry Hill, though it still needs approval from the town's historic districts commission, a separate review that the frozen parcels on Hartwell and Bedford Street don't have to clear.

If a single-family home you're considering sits within a block or two of any of these addresses, the question worth asking isn't "is this neighborhood in the reduced zoning district now." It's "does this specific parcel carry a zoning freeze that locks in the larger, pre-rollback rules." Those are two different answers, and only one of them tells you what the next seven years actually look like.

The friction that doesn't show up in a listing sheet

The 475 Bedford Street project shows the kind of issue that a median price search never will. A May 2026 letter to the editor in the Lexington Observer flagged that about half of the 9-acre site sits under gas, electric, and sewer easements where nothing can be built, and most of the remaining acreage is protected wetland. A building can only encroach on the required 50-foot buffer if the developer proves no other option is workable, and that review still needs to clear the town's Conservation Commission separately from the Planning Board approval it already has.

None of this means a home near these corridors is a bad buy. It means the due diligence looks different than it would on a quiet street with no pipeline activity nearby. Before you write an offer near Hartwell Avenue, Bedford Street, Concord Avenue, or Militia Drive, it's worth:

1. Asking whether any nearby parcel carries a zoning freeze that locks in the larger, pre-rollback zoning envelope, and through what year.
2. Pulling the Planning Board's site plan review file for that parcel, which will show unit count, parking design, and any outstanding wetland or stormwater conditions.
3. Checking whether the project has cleared Conservation Commission review, not just Planning Board approval, since those are separate hurdles with separate timelines.
4. Asking your agent whether traffic or flooding concerns were raised at public hearings, since those tend to surface in local reporting and town meeting minutes well before they show up in a home inspection.

What this means for the number you started with

The market's headline stats still point to a town under real pressure. Homes were fetching 101.74 percent of list price as of March 2026, though the share of homes selling above asking has fallen from 82.14 percent a year earlier to 43.75 percent, and price reductions rose from about 21 percent of listings to nearly 32 percent over the same stretch. That's not a market cooling off so much as a market absorbing more supply and more noise, both literal and political, than it saw a year ago.

The same rezoning district also shows what "affordable" actually means here. The cheapest unit at 89 Bedford Street is listed at $1.2 million. A few blocks away, the income-restricted lottery units at 93 Bedford Street, part of a separate 32-unit project called The Lex, are priced at $312,500 for a two-bedroom and $345,000 for a three-bedroom, available only to buyers at or below 80 percent of the area median income. Both projects sit inside the same half-mile stretch. The gap between them is the clearest illustration of who this zoning was written for, and who is actually able to use it.

Frequently asked questions

Does the 2025 rollback undo projects that were already approved? No. The rollback reduced the zoning district going forward. 17 Hartwell Avenue had its subdivision finalized on March 12, 2025, five days before the rollback vote, so it proceeds under the original rules and broke ground that July. 131 Hartwell Avenue and 475 Bedford Street finalized their subdivisions in June and July 2025, months after the vote, and each secured a separate zoning freeze on August 13, 2025 that locks in the same larger, pre-rollback zoning envelope through 2033.

How do I find out if a specific property is near a frozen parcel? The Town of Lexington posts project-level filings, including zoning freeze dates, on its MBTA Communities Zoning page and its Hartwell Avenue and Bedford Street project pages. A buyer's agent familiar with these filings can cross-reference a specific address against the active pipeline before you write an offer.

Will all this new construction bring single-family prices down? Nothing in the current data points that way. The pipeline is concentrated in a handful of corridors zoned for multifamily use, not in the single-family neighborhoods that make up most of the town, and the single-family median has continued climbing through the same period the pipeline expanded.

Lexington's zoning story is still being written street by street, and the corridors carrying the most activity right now aren't the ones a median price search will flag for you. If you're weighing a specific address against what's approved, frozen, or still pending nearby, I'd rather walk through the actual filings with you than guess from a listing sheet.
