Cleary Square Rezoning Won’t Make Your Lot a Building Site

There is already a six-story apartment building approved for Hyde Park. It sits on a 10,821-square-foot vacant lot at 30 Thorn Street, just off River Street, with 40 units and 19 parking spaces. It was first approved in 2018. By 2023 the Zoning Board of Appeal had granted its fourth one-year extension, according to Universal Hub. Today it is on the market as land, asking $1,299,000. That works out to about $32,500 per approved apartment.

I start there because on October 15 the city’s planning board voted to make six stories legal along much of Hyde Park Avenue in Cleary Square, and the obvious question for every owner near the square is what that does to the value of their house. My honest answer is: very little, for now. A rezoning map is permission. It is not a check in the mail. The only way a lot becomes worth more because of a zoning change is if someone can build on it, sell or rent what they built, and still have money left over to pay you. In Hyde Park in late 2026, at today’s construction costs and with mortgage rates above 7%, that leftover is close to zero. Hyde Park already has approved buildings that nobody is building, and that tells you more than any zoning map.

Below: what the board adopted, what the map allows, what seventeen months of Squares + Streets zoning produced in Roslindale Square, and what our MLS PIN data says property near Cleary Square sells for today.

What the board voted on October 15, and what it did not do

Two separate items on the October 15 Planning Department board agenda covered Cleary Square. Item 16 adopted the Cleary Square Squares + Streets Small Area Plan, the planning document that guides future development, street design and city investment. Item 17 asked the Zoning Commission to amend Zoning Map 12 and Article 69, the Hyde Park neighborhood article, so that Squares + Streets districts actually apply on the ground. The same petition removes the Neighborhood Business subdistricts the new districts replace and keeps the existing Neighborhood Design Overlay District in force.

The detail that matters most to owners: the new zoning is not in effect yet. The Zoning Commission has the Cleary Square text and map amendments on its November 18, 2026 hearing calendar. If the Commission adopts them, they go to the mayor and are then codified. Until then, the current Hyde Park zoning still controls every parcel in the square. The October text amendment also protects projects that apply for a permit before the first notice of the Zoning Commission hearing, so anything already in the pipeline is reviewed under the old rules.

One more correction, because I have seen it shared around. High-Profile’s headline paired the Cleary Square vote with “192 new homes.” That number is not Cleary Square. It is three unrelated projects approved the same night: 145 rentals at 201-207 Brighton Avenue in Allston, 23 at 1428 Dorchester Avenue, and 24 ownership units at 201 Hampden Street in Roxbury. The same agenda also approved two non-residential projects. The Cleary Square plan did not approve a single building. It changed what future buildings could ask for.

The map, three drafts later

The plan went through three draft maps. The March draft allowed up to seven stories on Hyde Park Avenue in the square and on both sides of River Street between Harvard Avenue and Hyde Park Avenue. The Hyde Park Neighborhood Association’s president, Mimi Turchinetz, told the Bulletin the March map was “far more aggressive, in terms of height and density, than we had thought.” The June revision replaced every seven-story S4 district with six-story S3-6 and cut part of River Street to four-story SC, citing community concerns. The October revision, summarized in the city’s October summary of changes, made the final adjustments.

Two things in that table are worth slowing down on. First, the cluster near Hyde Park Avenue and River Street went from seven stories in March to four by October. That is the corner the plan calls its catalytic site: a group of lots under common ownership next to the Hyde Park commuter rail station, where the city says there has been real redevelopment interest. The plan’s own housing estimate for that site dropped from 300 to 400 units to 150 to 200, of which about 25 to 40 would be income-restricted. Second, the extra height did not disappear. Some of it moved to Hyde Park Avenue between Winthrop and Everett Streets, which went from four stories in June to six in October.

Two parcels stay public. The plan keeps the free 111-space municipal lot off Winthrop Street, between Hyde Park Avenue and the library, as parking and defers any redevelopment for at least five years. The Planning Department will also start the disposition process on its own lot at 24 Pingree Street for affordable housing.

What SC and S3-6 actually allow

Squares + Streets is a family of zoning districts the city created in 2024 and has been mapping one neighborhood square at a time. SC and S3-6 are recent additions. The Zoning Commission added both in December 2025 in response to a petition from Hyde Park residents, which is why Cleary Square is the first place you will see them used at scale. According to the city’s Squares + Streets district materials, here is the height ladder:

A few rules matter as much as height:

• No parking minimums. Under the 2024 amendment to Article 23, off-street parking is not required on any lot in a Squares + Streets district. A builder can still provide parking. The zoning no longer forces it, which removes a cost that has killed a lot of small Boston projects. I priced what parking is worth in our Chelsea parking post.
• Lot coverage. S3-6 allows a building to cover 90% of a small lot. SC allows 70%. That is the real jump from today’s rules, more than the story count.
• Commercial on the main streets. SC is the same as S2 but capped at four stories, and it allows more commercial use on upper floors. Since January 2025, ground-floor apartments facing a main street need special permission.
• Affordability. Article 79, effective October 1, 2024, applies to projects of seven or more units. Rental projects set aside 17% at an average of 60% of area median income, plus another 3% for voucher holders, per the city’s inclusionary zoning page.
• Net Zero Carbon. The plan notes that a large project at the catalytic site would also have to comply with Article 37’s Net Zero Carbon zoning, which adds cost.

So once this is codified, a parcel on Hyde Park Avenue between Winthrop and Everett can legally host a six-story, 75-foot building with ground-floor retail and no required parking. The question is whether anyone can afford to build it.

Roslindale Square, seventeen months later

Hyde Park does not have to guess. Roslindale Square got its Squares + Streets map from the Zoning Commission on May 21, 2025, with S0 through S5 districts and the tallest S5 heights reserved for the publicly owned parcels around the Roslindale Village commuter rail lots. The city’s own presentation made the case clearly: of Roslindale’s 6,600 parcels, only 319, about 11%, were zoned to allow multifamily housing, and only 28 residential parcels had become multifamily in fifteen years.

Here is everything I could find filed or approved under the new Roslindale zoning since then:

That comes to about 85 units filed or approved in seventeen months, and I could not confirm any of them under construction. The city’s year-end 2025 update counted one approval and four projects under review, so a few more may be in the pipeline. The one furthest along is the B’nai B’rith project, which the city calls one of the first developments permitted under Squares + Streets. It is fully subsidized. The city’s federal HOME funding notice puts its total cost at about $32.7 million, roughly $797,700 per apartment.

The one that tells you the most is 4301 Washington Street. It is the clean test case: four stories, 16 condos, no zoning relief needed. The board approved it at its July 16 meeting. On August 18 it went on the market as land at $2.6 million. It is now asking $2,395,000. The listing says the building permit is in process and that demolition is contracted. That is $149,700 per approved condo, and the developer would apparently rather sell the approval than build it. Roslindale is a stronger market than Hyde Park: our MLS PIN data shows Roslindale single-families closing at a median $800,000 over the last twelve months against $663,000 in Hyde Park. If the rezoning has not produced a market-rate building in Roslindale Square yet, Cleary Square will not get one quickly either.

Hyde Park already has approved buildings for sale

When I searched active MLS PIN listings in Hyde Park this week, 30 Thorn Street was not the only one. Several approved development sites are being sold as approvals rather than built. These are asking prices, not closed sales, but they show where the market is.

Look at the pattern. The six-story, 40-unit approval is the cheapest per unit by a wide margin, and the six townhouses are the most expensive. Sellers are asking far more per unit for the small, simple project than for the mid-rise, and the six-story site has been on the market since June. That is the opposite of what the zoning map assumes. A six-story building means an elevator, a commercial building code, structured steel or concrete at the base, union-scale labor in many cases, and a long construction loan. A row of townhouses avoids most of that. Rezoning to six stories gives an owner a type of project the market currently values least.

There is also a pending land sale at 1139 Hyde Park Avenue, a little more than 11,000 square feet about a third of a mile from the square. It was listed at $750,000 with a note that the city had been supportive of up to four units. It is now pending, after the asking price was cut to $380,000.

34 Oak Street: what new condos near the square sell for

To know whether a building pencils you need a sale price, and Cleary Square has one. 34 Oak Street, about a block and a half from the square, is a new 2026 condo building with units on three floors. Here is every unit in our MLS PIN feed and where it stands.

The six closings ran from $490,000 for a 664-square-foot one-bedroom to $700,000 for two of the three-bedrooms. All six closed at their original asking price, and the median works out to about $640 per square foot. That is a healthy number for Hyde Park, where the median single-family sold for $423 per square foot over the same twelve months. But the building also shows how slowly new units sell at 7%+ rates. Seven earlier listings in the building, under single-digit unit numbers, were canceled or expired. Five units are on the market now at $475,000 to $645,000. Six sold in about seven weeks, and nothing has closed since July 8.

So $640 a square foot, on a building that still has five units for sale after its spring run, is the best real benchmark for a new condo near Cleary Square. Now compare it with what a building costs.

Why a six-story building on Hyde Park Avenue does not pencil yet

On the same night it adopted the Cleary Square plan, the board approved Chapter 121B tax agreements for four large, already-approved rental projects in Charlestown, Allston and Brighton: about 1,400 units and an estimated $31.5 million in deferred property taxes. I covered that program in detail in my post on the stalled-project tax relief, so here I’ll use only one line from that night. Planning’s Reuben Kantor said, per Banker & Tradesman: “We talked to at least 40 developers and some of them said they need two, three or four times this amount to make this work.” That is about $22,500 a unit, on projects in neighborhoods where rents run higher than Hyde Park’s, and developers told the city it is not enough.

Here is the same math at Hyde Park scale. It is a back-of-the-envelope check, not a pro forma, and I’ll show every assumption.

The rental line uses our MLS PIN closed-lease data. The median Hyde Park two-bedroom lease over the last twelve months was $2,500 a month, across 37 leases. New Roslindale two-bedrooms built since 2015 leased at a median $3,175. Give a brand-new Hyde Park apartment $3,000 a month, take 35% off for expenses, and you have about $23,400 a year of net income. Banker & Tradesman reported that investors want about a 6.5% yield on cost before they will fund a Boston project. $23,400 divided by 6.5% is $360,000. That is the most you can spend per apartment, land included, and still raise the money. At $2,500 a month it is $300,000.

The Globe Spotlight team put the cost to finance and build new Greater Boston housing at $500,000 to $600,000 a unit. That was in 2023, and the rate backdrop is no easier now: Freddie Mac’s survey had the 30-year mortgage at 7.40% on October 15, up from 6.27% a year earlier. The supportable number is $140,000 to $300,000 per apartment short of the cost. Even four times the October tax deferral, about $90,000 a unit, does not close that at Hyde Park rents.

Condos are closer but still short. Price a market unit at $600,000, roughly the 34 Oak Street median. A building of seven or more units owes 17% of them as income-restricted, and the city’s 2025 price sheet caps a two-bedroom at $284,970 to $368,973 depending on the income tier. Take a 15% margin, which is what a lender will expect the developer to earn, and the building can spend about $470,000 per unit on everything, land included. The city’s own consultants reached a similar conclusion in 2023: in the inclusionary zoning feasibility study, a 50-unit wood-frame condo building in the Hyde Park, Roslindale, Jamaica Plain and West Roxbury market was “not financially feasible.”

Put those numbers on a typical lot. Hyde Park’s median two-family lot in our data is about 6,100 square feet. At S3-6’s 90% coverage and six stories, and using the same ratio as the approved 30 Thorn Street building, that is about 22 apartments on paper. At a gap of $140,000 or more a unit, the building is about $3 million short. A typical two-family lot works out to roughly $40,000 per apartment at today’s two-family prices, far less than the gap, so the amount left over to pay for land is below zero. Until rents rise, costs fall or someone subsidizes it, a builder can pay nothing for that lot. That is why the approved sites in the previous section are priced the way they are.

What a Hyde Park lot trades for today

Now the other side: what Hyde Park property actually sells for. This is MLS PIN closed sales in ZIP code 02136 from October 1, 2025 through October 21, 2026.

Three things stand out. First, there is no Cleary Square premium in house prices. A single-family within half a mile of the square sold for about the same median price as one a mile out. Homes near the square show a little more per square foot, which I’d put down to the commuter rail and the 32 bus, not the zoning map. Buyers are not paying for development potential, because there isn’t any yet.

Second, look at land against houses. Hyde Park has had six residential land sales on MLS PIN since January 2024. They ranged from $150,000 to $750,000, with a median of $222,500, and three of the six closed at 85% or less of their original asking price. Meanwhile the median two-family, typically about 2,300 square feet on a 6,100-square-foot lot, sold for $927,000 at slightly over its original ask. In Hyde Park right now, a lot with a house on it is worth far more to an owner-occupant or landlord than the same lot is worth to a builder.

Third, the top bidders near the square are buying to live in or rent out. A two-family a third of a mile away closed in September at $935,000 on a 4,356-square-foot lot. A developer would need a building that produces more than $935,000 of land value to outbid that buyer. At the numbers in the last section, it produces none.

How I’d price a parcel inside the new districts

None of this means the rezoning does nothing. It means the value is an option, and right now the option is far from paying off. Rates come down, construction costs ease, Hyde Park rents rise toward Roslindale’s, the city expands subsidy. Any of those could make the option worth something. You can price that honestly without pretending it is already worth money.

If you own a house or two-family inside the S3-6 or SC area:

1. Price it as what it is. Your value is set by the house comps in the table above, not by six stories. If you want a number, start with our home value tool and then talk to someone who knows the street.
2. Look up your parcel on the October map. The district lines changed three times, and River Street and Hyde Park Avenue moved in opposite directions in the last revision. Don’t rely on what a neighbor heard in March.
3. Be careful with developer calls. An offer contingent on permits, financing and the Zoning Commission vote can tie up your property for a year or more. Ask how long the contingency runs and what happens to the deposit. 30 Thorn Street was approved eight years ago and is still not built.
4. Only a few parcels have real development value now. Large lots, commercial buildings that are already underused, and land under one owner that can be combined, like the catalytic site at Hyde Park Avenue and River Street. A single-family on a 5,000-square-foot lot is not one of them.

If you are buying near Cleary Square:

1. Don’t pay a development premium. The sellers have not priced one in and you shouldn’t either. At 7.40%, you are paying for a house you can live in or rent out.
2. Do check what could go up next door. If the parcel beside you is mapped S3-6, the law will allow a 75-foot building covering 90% of its lot. It probably won’t be built soon, but it is now legal, and that matters more for a house you plan to keep for fifteen years than for a quick resale.
3. Treat transit as the real asset. Hyde Park station is under 20 minutes to South Station by the plan’s count, Fairmount on the Fairmount Line is about 25, and nearly 4,000 people a day use the Cleary Square bus stops. That will hold its value whether or not anything gets built.

If you build small projects: it can be cheaper to buy an approval than to get one. The approved sites on the market are asking $32,500 to $200,000 per unit, and some have already been cut. Underwrite at Hyde Park rents, $2,500 for a two-bedroom, not Roslindale’s. Under seven units you avoid the affordability set-aside, and the SC and S0 to S2 districts keep you at four or five stories. Stack three or more units and you are in the commercial building code, which I priced in the triple-decker cost post. More of our work on this is in the investment property section.

My read

This is not an argument against the plan. The neighborhood pushed for SC and S3-6 so it would not get a one-size-fits-all map, the city revised the map three times in response, and Hyde Park Avenue next to a commuter rail station is a sensible place for more housing. But I would be doing owners a disservice if I said the October 15 vote put money in their pockets. It legalized buildings that do not pencil at today’s rents, costs and rates, in a neighborhood where approved six-story projects are being sold rather than built. When the economics change, these districts will matter, and owners with the right parcels will be glad the map is already in place. Until then, a house near Cleary Square is worth what a house near Cleary Square sells for.

If you own in the new districts and want to know what your property is actually worth, as a house and as a site, reach out. We will run the comps and the site math, and tell you which one is higher. You can also read our Hyde Park neighborhood guide and the Roslindale guide for broader context.
