Figures current as of August 13, 2026. Project status in this post should be reviewed by February 2027 as the Redevelopment Authority process advances.
On August 10, 2026, Watertown's City Council sat as its Redevelopment Authority for the first discussion of the Demonstration Project, a plan to replace the public parking lot behind CVS in Watertown Square with 247 apartments, a garage, and a park. No votes were taken, and nothing is approved. Here is what the project is, whose property is in the footprint, and what comes next if you own Watertown real estate near the Square.
- Watertown's City Council convened as the Redevelopment Authority on August 10, 2026 at the Watertown Free Public Library for an initial discussion of the Watertown Square Demonstration Project, with no votes taken and no decisions made (City of Watertown, Watertown Square Improvements notice, July 22, 2026).
- The April 2026 draft plan holds 247 apartments, 190 residential parking spaces, and a public garage of either 370 spaces on four stories or 434 spaces on five, replacing a surface lot that fits 252 cars today, with 15 percent of the housing designated affordable (Watertown News, April 9, 2026).
- The City would build and own the garage while a private partner develops the housing, and City Manager George Proakis has stressed that no agreements have been made and the plan remains in draft form (WCA-TV, April 2026).
- The Watertown Square zoning exists to satisfy the MBTA Communities Law requirement, in force since January 2021, that Watertown zone for 1,701 multi-family homes by right, a capacity figure rather than a construction mandate (City of Watertown, Watertown Square MBTA Communities FAQ).
What is the Watertown Square Demonstration Project?
The Demonstration Project is Watertown's plan to rebuild the block behind CVS, roughly bounded by Church Street, Summer Street, and Mount Auburn Street, into 247 apartments over ground floor retail, a public parking garage, and a new public park.
The city drafted two versions in April 2026. Both hold the same 247 homes; the difference is the garage, four stories or five, and how much commercial space wraps it. Either way the garage replaces and expands the public parking on the lot today, which is the piece designed to keep Square businesses whole while the rest of the block builds out.
Watertown is calling it a demonstration for a reason. The Watertown Square Area Plan rezoned the Square for thousands of by right homes on paper, and this block, where the city already controls the biggest parcel, is where it can prove the plan produces real buildings, real parking, and real public space rather than a map nobody acts on.
Whose property sits in the Demonstration Project footprint?
The draft footprint takes in the municipal lot, the Gray Block storefronts holding Tresca's, a salon, and a laundromat, the former Registry of Motor Vehicles building, four houses on Spring and Summer streets, and slivers of adjacent business land (Watertown News, April 9, 2026).
The same draft pencils property acquisition and relocation for 2027 through 2029, construction for 2029 and 2030, a 12,300 square foot green space fronting Spring Street, and a garage opening in 2031.
A council sitting as a redevelopment authority is the legal structure Massachusetts cities use to assemble land, relocate occupants, and convey parcels to a chosen developer. It is a heavier tool than a rezoning, which is why Monday's session matters more than another planning meeting. The city has not bought anything, and the City Manager has been clear that no agreements exist. The structure for doing so is now warmed up.
If you own one of those parcels, or a building that abuts them, the window between now and 2027 is when your position is strongest. Establish what your property is worth with the development potential priced in, understand your tenants' lease terms if you hold commercial space, and go into any conversation with the city knowing your number rather than reacting to theirs.
How does the project connect to MBTA 3A zoning?
The Demonstration Project is the first city led build under the Watertown Square Area Plan, the rezoning Watertown adopted to comply with the MBTA Communities Law.
Section 3A requires MBTA served cities and towns to zone at least one district of reasonable size where multi-family housing is permitted by right at a minimum gross density of 15 units per acre near transit, and communities that refuse lose eligibility for a list of state funding programs (EOHLC, mass.gov).
Watertown answered with the Square plan, adopted in November 2024 and accepted by the state the following spring, a history we walked through in our owner's guide to the Watertown Square rezoning.
By right is the phrase carrying the money. A project that fits the district standards goes through site plan review instead of a special permit fight, which collapses timeline risk for whoever partners with the city here, and for private owners redeveloping their own parcels nearby. That mechanic, and what it does to land value, is the same one we track across MBTA 3A zoning in Greater Boston.
What should you do if you own near Watertown Square?
Read your property against a block that now has a construction decade attached to it, because the project changes different owners' math in different ways.
For owners in or against the footprint, the move is covered above: know your number early. For commercial owners on Main Street and Mount Auburn Street outside the footprint, the plan is mostly upside, a bigger public garage and 247 households within a short walk of every storefront, with the cost being years of construction between here and there.
For small multifamily owners around the Square, 247 new units are not rent competition to fear this decade. They arrive years out and lease at the top of the market first. The nearer effect is on land value: a city spending its own capital to prove the Square plan works tells every developer the by right zoning is real, and 3A zoning is already moving property values in districts like this one.
For investors, the signal is the city's posture. Watertown is not waiting for a developer to move first; it is putting the garage on its own balance sheet to unlock the block. Underwriting parcels inside a district the city is actively de-risking is the kind of work we do on the multifamily investing side.
Frequently asked questions
What is the Watertown Square Demonstration Project?
The Watertown Square Demonstration Project is the City of Watertown's draft plan to redevelop the municipal parking lot behind CVS and neighboring parcels into 247 apartments, ground floor retail, a public parking garage, and a public park, as the first built test of the Watertown Square Area Plan.
Where exactly would the Watertown Square garage and apartments be built?
The draft footprint sits behind CVS in the heart of Watertown Square, roughly bounded by Church Street, Summer Street, and Mount Auburn Street, with the planned park fronting Spring Street.
When does construction start on the Watertown Square project?
No construction is approved as of August 13, 2026; the draft timeline shows property acquisition and relocation from 2027 to 2029, design and construction through 2030, and a garage opening in 2031.
Will Watertown use eminent domain to take property for the Demonstration Project?
The City has not said it will take any property, and City Manager George Proakis has stated that no agreements have been made; the City Council sitting as a Redevelopment Authority is the structure that gives Watertown the legal tools to assemble the parcels, with terms for each owner still to be negotiated.
How many apartments and parking spaces would the Demonstration Project add?
The draft plan holds 247 apartments with 190 residential parking spaces, plus a public garage of either 370 or 434 spaces replacing a 252 space surface lot, and 15 percent of the apartments would be designated affordable.
Does the Demonstration Project change what private owners can build near Watertown Square?
No, private development rights around Watertown Square are set by the Watertown Square Area Plan zoning already in effect, which allows multi-family housing by right in its districts, and the Demonstration Project is the city's own build within that framework rather than a new rule for private land.
Where this leaves Watertown Square owners
Watertown moved its Square plan from zoning text to an execution structure, and the draft on the table names the parcels, the unit count, and the years. Nothing is signed, which is why now is the time to understand what the plan does to your property. PH Realty Group works Watertown Square every week on sales, leasing, and acquisitions, and we are happy to walk through what the Demonstration Project means for your building.
