Greenwich is Building. Here’s Everything You Need to Know.
A wave of new multi-family housing is reshaping Greenwich’s neighborhoods; driven by a state law most residents have never heard of. Our comprehensive new report maps every approved, under-construction, and proposed development across all of Greenwich’s communities.
799+ Approved & Pipeline Units – 16 Projects Catalogued – 52% Units Enabled Solely by State Law
The short explanation: Connecticut’s affordable housing statute, CGS Section 8-30g, gives developers the legal authority to bypass local zoning in towns where less than 10% of housing stock qualifies as affordable. Greenwich currently sits at just 5.7% – well below that threshold – and shows no realistic path to reaching it anytime soon. That gap has opened a door that developers are walking through, one project at a time, in every corner of town.
We’ve spent months compiling what we believe is the most comprehensive available overview of every major multi-family project in Greenwich: approved developments, projects under construction, projects in the pipeline, and brand-new proposals that most residents don’t yet know about. Here are the highlights.
The Biggest Projects Already Approved
The most significant development in Greenwich’s immediate pipeline is Benedict Court and Benedict Place, a 120-unit, six-story rental building approved in May 2024 directly behind St. Mary Church, steps from Greenwich Avenue. Forty percent of its units (48 apartments) will be deed-restricted affordable. Demolition of the existing structures was underway as of late 2025, making this the furthest along of any major project in town. I will be able to personally report on its progress as my office window looks directly out over the building site!
When it comes to new units for sale, the former Honda dealership site at the foot of Mason Street is approved for 75 condominiums, including 24 below-market units, across two multi-story buildings straddling the street near the Metro-North station. The developer sued the town over conditions of approval, but demolition of the existing structures was posted in late 2025, and the state committed $8 million in environmental remediation grants in December 2025 to advance the project. TeamJGB was invited to preview early plans for this project last year, and we are excited to report that a full service amenity building will finally be arriving in Greenwich. Call us for details on this one!
It’s Not Just Downtown
Cos Cob is emerging as a secondary node of new density. The mixed-use building at 100 East Putnam Avenue (on the former Friendly’s/M&T Bank site near CVS) was completed offering 22 apartments including 5 workforce-rate units and ground-floor commercial space. And a 15-unit 8-30g rental building approved at 4 Orchard Street, next to Cos Cob School, represents the neighborhood’s earlier introduction to state-statute-enabled development.
On the western side of town, a 170-unit rental project is proposed at the former Greenwich Woods nursing home site on King Street, while a smaller adaptive-reuse project at 1188 King Street (the former RegalCare facility) has already been approved for 17 apartments under a new state law enabling nursing home conversions.
“The commission has recently approved over 1,000 new housing units in Greenwich — but they have yet to be built. Builders tell us they are struggling with increases in materials costs, interest rate hikes, and tariff uncertainty.”
— P&Z Commission Chair Margarita Alban, June 2025
The 8-30g Reality Check
Here’s the number that matters most: of the 799+ units in Greenwich’s current pipeline, we estimate that approximately 52% exist solely because of 8-30g. These are projects that were either previously denied under local zoning, or that simply could not have been proposed at their current scale without state-law authority to override Greenwich’s own regulations.
What this means for you: Without 8-30g, Greenwich’s multi-family pipeline would essentially consist of the Quarry Knolls public expansion (275 units), a handful of modest workforce-housing projects, and perhaps the J Lofts at 240 Greenwich Ave. Every other significant project – Benedict Court, Mason Street, Oak Ridge, Greenwich Woods, 4 Orchard Street – owes its existence to the state statute. Supply is expanding not because Greenwich chose to, but because Connecticut law compels it.
What’s Coming Next
The approved projects are only part of the story. A new wave of proposals is working its way through pre-application and review, and some are generating significant community attention. In Pemberwick, an 84-unit 8-30g development is proposed on the Comly Avenue parking lot alongside the Byram River, though flooding concerns and dam safety issues have complicated multiple prior iterations of the site. In Riverside, a 20-unit development at 1143 East Putnam Avenue has been waiting for wetlands approval since 2021. In Cos Cob, Greenwich Communities is pursuing a development on a town-owned Strickland Road parking lot.
Meanwhile, Fareri Associates – the same developer behind J Lofts at 240 Greenwich Avenue – has filed a site plan application to convert the mostly vacant office building at 1 East Weaver Street (right across from the entrance to Splash car wash) into 44 market-rate apartments. Unusually, this proposal has no affordable or workforce component, making it one of the only large multi-family applications in recent years to proceed entirely under standard local zoning.
What It Means for Buyers and Sellers
For buyers, the pipeline represents a meaningful expansion of multi-family inventory in a market that has historically offered very little, particularly in downtown Greenwich and Cos Cob. New rental stock will create optionality for those not yet ready to buy, while the Mason Street condominiums will bring new for-sale units, the majority of which will be offered at a luxury price point, in an exceptionally convenient location.
For sellers, particularly those near the larger approved projects, the calculus is more nuanced. Increased density in their immediate area has mixed effects on single-family values; transit access and walkability benefits can offset concerns about bulk and traffic.
For investors, the opportunity is clear: Greenwich’s multi-family market is being fundamentally restructured by forces that are unlikely to reverse before the town reaches the state’s 10% affordability threshold: a milestone that is still well over a decade away at the current pace.
