Weston voters approved the town's MBTA Communities zoning plan 387 to 86 at Special Town Meeting on Oct. 15, 2025, according to the Weston Observer. Seven weeks later, the state's Executive Office of Housing and Livable Communities found that Weston "is compliant," crediting the town with 750 units of as-of-right capacity across 104.8 acres. A year after that vote, the number of new homes rising under that zoning is zero.
The housing actually going up in Weston arrived by a different route. It is mostly rental and age-restricted, and it moves on timelines measured in years. If you are comparing Weston against Wellesley, Needham or Newton, the 750 figure tells you very little about the next few years of inventory.
Where the 750 Units Sit
Most of the 750 units of capacity land on just one parcel. The approved bylaw allows up to 480 units at 133 Boston Post Road, the BXP office campus near the Kendal Green commuter rail station, split across three subdistricts of 100, 280 and 100 units. BXP's September 2025 presentation to the town showed the phases as townhomes first, then 280 apartments beside the rail line, then 100 condos on the site of the existing office building. The Weston Observer reported that the final phase depends on the office building coming down.
The rest of the capacity was mapped largely onto land that already holds housing or has housing underway. In the fall 2025 proposal, the other districts covered Merriam Village, which already has 62 age-restricted units, the 751 Boston Post Road site, and the Charles River Recovery and Maplewood Assisted Living properties. The Observer reported that any additional housing at Merriam Village would need an amended development agreement and another Town Meeting vote, and wasn't expected soon.
So almost everything new that 3A could produce comes down to the BXP campus. After the vote, BXP's vice president told the Weston Observer the company was not yet ready to discuss its larger project plan. We found no record of a site plan filing, a named development partner, or a construction schedule for 133 Boston Post Road since then. The state's compliance letter also carried an open condition. Weston owed an economic feasibility analysis of its 15% affordability requirement within 180 days, and the letter says that analysis had not been received at the time of review.
The Mechanism That Is Building Housing
The projects with real momentum in Weston trace back to one number. On the state's Subsidized Housing Inventory list dated Sept. 30, 2025, Weston had 340 qualifying units out of 3,999 year-round homes, or 8.50%. As the Weston Observer has explained, a town at or above 10% can turn down Chapter 40B applications without the developer being able to appeal. Below that line, developers can get past parts of local zoning, and Weston is below it.
Here is where each major project stood heading into fall 2026:
| Project | Route | Units | Product | Status |
|---|---|---|---|---|
| Modera Weston, 751 Boston Post Road | Chapter 40B | 172, with 43 affordable | Rental apartments and townhomes | Preleasing; completion estimated September 2027 |
| 518 South Ave | Chapter 40B | 180 | Four-story apartment building | Superior Court upheld the permit in June 2026; Select Board and abutters appealed in July |
| 104 Boston Post Road | Chapter 40B | 150 | Apartment complex | ZBA denied it in 2017; the state Housing Appeals Committee later permitted it; Weston and Cambridge appealed; argued May 6, 2026, now under advisement |
| Reserve Weston, Regis College | Senior Living Community Overlay District | 215 | Age-restricted housing | Planning Board hearing Oct. 21; Town Meeting Nov. 23 |
| 133 Boston Post Road, BXP | MBTA Communities zoning | Up to 480 | Townhomes, apartments, condos | No filing found |
These projects take a long time to clear. The 104 Boston Post Road proposal was denied nine years ago and is still in court. Modera's site got its 40B comprehensive permit from the Zoning Board of Appeals in November 2020, went through an appeal and a revised permit in 2021, and was cut from 180 to 172 units in 2022, the Weston Observer reported. If it finishes in September 2027 as estimated, it will have taken almost seven years from permit to completion.
The 751 Boston Post Road site sits inside one of the new 3A districts, which caps it at 100 units. The 172-unit project was already moving forward under 40B, and the Observer reported in 2025 that switching it to 3A was considered very unlikely. That leaves the one building that looks like new 3A housing as a 40B project that came first.
What a Weston Address Rents For
Modera adds something Weston's market has rarely had: a posted price for living in town without owning land. Mill Creek Residential's listing quoted move-in-ready leases from $7,510 a month for a three-bedroom, two-bath, 1,455-square-foot home, according to the Weston Observer's July 31, 2026 report. That works out to roughly $5.16 per square foot per month, or about $90,000 a year for that unit. The 43 affordable units are capped at 80% of area median income, and their rents were listed at $2,401 for a one-bedroom, $2,861 for a two-bedroom and $3,280 for a three-bedroom.
Mill Creek's Doug Arsham called it "the first professionally managed community of its kind in Weston" in a press release quoted by the Weston Observer. For anyone weighing a move to town, that matters. A household can now try Weston on a lease while the move is decided, but it pays a top-of-market rate to do it. For someone in a large Weston house, Modera is a rental option, not a purchase.
The Vote That Could Add Owner-Style Product
The only near-term project that includes townhomes is Reserve Weston. It comes up at the Nov. 23 Special Town Meeting through a zoning change, not through 3A. HYM Investment Group, the applicant, has proposed 215 age-restricted units on a 28.251-acre piece of Regis College's 59.253-acre campus at 300 Wellesley St. The request would create a Senior Living Community Overlay District.
According to the Weston Observer's account of the June 2026 redesign, the plan breaks down as:
- 112 independent living units
- 73 units in an assisted living and memory care building
- 30 over-55 townhomes
The September revisions held buildings to three stories, with height limits of 37 feet in one zone and 59 feet in the other, and raised the natural open space buffer from 10% to 20%, the Weston Observer reported. On affordability, the Weston Observer reported that HYM offered the town two choices. It could reserve 10% of units as on-site affordable housing, which the Observer put at about 18 units, or pay $300,000 per unit for off-site affordable housing chosen by the town, equal to 15% of units, or 27 units worth about $8.1 million. Both counts work out to roughly 180 units rather than the full 215, and the report doesn't say which units are excluded from the base. HYM also committed to a fall traffic study with an independent peer reviewer.
Several basics are still open. We found no source confirming whether the 30 townhomes will be sold, rented or offered under an entrance-fee model, and no operator has been named. HYM did not present prices at a March hearing. The Weston Observer cited a regional independent living range of $11,000 to $15,000 a month or more, depending on care. Regis COO Tom Pistorino told the Weston Observer that the land sale depends on rezoning and permitting, and that otherwise the parcel could go back on the market for another large-scale use.
What This Means for the Single-Family Market
The new Weston homes that are permitted, preleasing or headed to a vote are rentals, age-restricted units, or apartments still in court. Even if Reserve Weston passes in November, it adds 30 over-55 townhomes. BXP's 100 townhomes have no filing behind them.
For someone shopping Weston's single-family market, the competitive pool is largely the existing housing stock. The 750-unit headline doesn't change that on any timeline we can document. That is why Weston's acreage, private roads, and teardown potential still drive pricing more than new supply does. It also means the Nov. 23 vote matters most to longtime owners thinking about whether there is a next home for them inside town limits.
FAQ
Does the MBTA Communities zoning require anything to be built? No. It allows multifamily housing by right in the mapped districts. Whether anything gets built depends on property owners filing projects, and at 133 Boston Post Road we found no filing.
When does Modera Weston finish? The Weston Observer reported in September 2026 that the complex was still under construction, with completion estimated for September 2027.
Where can residents follow Reserve Weston before Town Meeting? The Planning Board's public hearing on the rezoning is set for Oct. 21, 2026, per the town's hearing notice, ahead of the Nov. 23 Special Town Meeting.
Pricing a Weston home depends on knowing which competing supply is real and which only exists on a zoning map.
