Brookline Raised Taxes and Rezoned Route 9 in the Same Month. That Is Not a Coincidence.

Say you are under agreement on a condo in Brookline this fall. You pull the current tax bill off the listing sheet, run it through your mortgage calculator, and the number works. What the listing sheet will not tell you is that the bill you are budgeting against is already out of date. Brookline voters approved a property tax override in May 2026 that phases in over three fiscal years, which means the number on your closing disclosure this year is not the number you will owe in 2028. It is the first of three increases, not the whole story.
That phase-in is a small mechanical detail. The bigger story is what happened three weeks after that override vote, when Town Meeting approved the largest rezoning in Brookline's recent history by a landslide. Read those two events separately and they look contradictory: a town votes to raise its own taxes, then turns around and clears the way for a hotel and 266 new residential units on Route 9. Read them together and they are the same decision, made twice, for the same reason.
On May 5, 2026, Brookline residents approved a $23.25 million property tax override by roughly a 60 to 40 margin, with turnout topping 34 percent, the highest ever recorded in a town election here. The override phases in through fiscal 2029. Town officials have said that without it, the total tax levy would still have climbed 11 percent over three years from normal growth and existing debt. With it, that climb becomes 18 percent. The difference bought the town $17.94 million for schools and $5.31 million for municipal departments, avoiding cuts that would have eliminated a fire engine and roughly 240 full-time town and school positions.
On May 28, Town Meeting voted 217 to 20 to approve the Chestnut Hill Commercial Area Study, the zoning framework that lets City Realty Group redevelop the aging office park at 1280 to 1330 Boylston Street. The approved project is a three-building mixed-use complex with a 200-room hotel, 266 apartments and condominiums, medical office space, and ground-floor retail. Town planners estimate the project's net fiscal impact, meaning tax revenue collected minus the cost of services the town has to provide, at $4.2 million to $6.3 million a year once it is fully built out. City Realty is also contributing $11 million to Brookline's Affordable Housing Trust Fund and $12 million toward transportation and public safety improvements. Construction is not expected to start until 2028, after the project clears state environmental review and Brookline's special permit process.
Two votes. Same month. Same underlying math.
Here is the part that gets lost when this story is told as a simple win for density. Chapter 40B, the state law that lets developers bypass local zoning if a town's affordable housing stock falls below a threshold, meant Brookline was not actually choosing between a rezoned commercial district and no development at all. City Realty had already signaled, about a year before the May vote, that it would pursue a residential-only project under Chapter 40B if the commercial rezoning failed. That path would have brought hundreds of apartments to the same site without meaningful commercial tax revenue and without the town's usual design review.
So the real choice on the warrant was never density versus no density. It was development that funds the town versus development that does not. Once you see it that way, a 217 to 20 vote three weeks after an 18 percent tax hike stops looking like whiplash and starts looking like consistency. A body of Town Meeting members who had just voted to squeeze more out of residential taxpayers had every reason to grab the version of growth that brought in commercial dollars instead.
Adam Guren, a Boston University economist who studies housing markets and lives in Brookline, put the underlying tension this way when discussing the override debate:
"If you change town services, you change the value of living in Brookline relative to surrounding neighborhoods, which will then have knock-on effects on the assessed value of the property stock and the tax base."
That is the loop Brookline is trying to manage. Cut services and the town's premium over neighboring communities erodes, which eventually erodes the tax base that funds those services. Raise taxes too far on residents alone and you strain the same premium from a different direction. Commercial development is the one lever that adds revenue without asking homeowners to absorb it directly, which is exactly why the two newest members of the Select Board, Amanda Zimmerman and Anthony Buono, both campaigned this spring on broadening the commercial and residential tax base rather than relying on repeated overrides.
The mechanics matter if you are pricing a purchase. Brookline's fiscal 2026 residential tax rate is $10.24 per $1,000 of assessed value, up from $9.87 the year before. The override adds another $0.30 per $1,000 as it phases in. The median-valued single-family home in town, assessed at $2.04 million, saw its fiscal 2026 tax bill rise 6.1 percent to $20,904, before the override's phase-in adds anything further. Statewide comparisons cited during the override campaign put Brookline's average single-family tax bill at $26,237, a figure that trails only Weston among Massachusetts communities. The median condo bill rose 5.5 percent to $4,704. Multifamily bills, the ones investors carry, climbed about 6.5 percent.
None of those figures include the override's later phases. Town of Brookline real estate tax bills for the current cycle went out on June 30, 2026, with payment due August 3. If you are shopping right now, the bill you see on a listing reflects only the first phase-in year. Anyone running conservative numbers should model the town's own stated trajectory, an 18 percent cumulative increase through fiscal 2029, rather than assuming next year looks like this year.
If you are a first-time or entry-level buyer, the dollar increases on a condo are smaller in absolute terms than on a single-family home, but they still compound. Model your carrying costs three years out, not just at closing, and ask whether the property qualifies for any state or town homebuyer assistance programs before you finalize your offer.
If you are a move-up family prioritizing schools, the override protected the programs that justify Brookline's price premium over neighboring towns. That protection came at a cost you are now funding for the next three fiscal years. Factor the full phase-in into your affordability math rather than the first year's number.
If you are an investor or small-scale landlord, multifamily tax bills are already rising faster than commercial ones under the town's current rate structure. Build a 6 to 7 percent annual tax growth assumption into your rent projections rather than the 2.5 percent baseline Proposition 2½ nominally allows, since overrides have repeatedly pushed actual growth well past that ceiling.
If you are selling or considering selling near Chestnut Hill, the rezoning vote answered the biggest open question buyers had about the neighborhood's future. You can now point to a resolved project with a defined scope, a construction timeline starting in 2028, and specific community benefits, rather than an open-ended fight that made buyers hesitant to commit.
Local MLS figures through the first half of 2026 show a market splitting by property type. Condos are trading briskly, averaging $1.38 million across roughly 149 closed sales year to date, up from about $1.22 million over the same period a year earlier, with inventory tight enough to favor sellers. Single-family homes are moving at a more measured pace, averaging just over $3 million across roughly 48 closed sales, with enough inventory on the market to call it a more balanced negotiation than the condo segment. In the back half of July alone, 20 homes changed hands in town, ranging from a $565,000 condo near Washington Square to a $5.35 million single-family in Chestnut Hill, a spread that captures how differently this market behaves depending on which segment you are shopping.
None of that pricing exists in a vacuum. Buyers weighing a Brookline purchase against a comparable one in a neighboring town are not just comparing today's list price. They are comparing a town that has shown, twice in one spring, that it will use every fiscal tool available, tax overrides and commercial rezoning alike, to protect the services that support those prices. That is either reassuring or a reason for caution depending on your own tolerance for rising carrying costs, but it should not be a surprise.
Will Brookline ask for another override after this one phases in? Town budget documents describe a structural deficit driven by health insurance and special education costs rising faster than the 2.5 percent Proposition 2½ ceiling allows. The Route 9 project's commercial revenue will not fully offset that gap on its own, and it will not start generating tax dollars until construction wraps sometime after 2028. Treat another override request in the coming years as a real possibility, not a remote one.
Does the Route 9 project affect property values near Chestnut Hill right now? Construction has not started, and the special permit process is still ahead. Some buyers may factor in future construction disruption between 2028 and beyond, while others may value the resolved uncertainty and the transportation and public safety investment the project brings. Either way, the vote removed a question mark that had been hanging over the area since at least 2023.
If you are weighing a purchase in Brookline against another Greater Boston town, the tax trajectory deserves the same scrutiny as the sale price.
