Boston Building Permits Fall as 2026 Home Listings Rise

At an open house in South Boston this spring, a buyer looked at the stack of listing sheets on the counter, more than she had seen in a couple of years, and said the thing I have been hearing all season. “So the shortage is finally over, right?”

I understand why it feels that way. There are more homes for sale in Boston than there were a year ago, some of them are cutting their asking price, and buyers who spent 2022 and 2023 losing bidding wars are finally getting a little room to breathe. If you read only the inventory number, the crisis looks like it is easing.

It is not, and the reason is a second number almost nobody at that open house is watching. There are two ways to count housing, and they measure completely different things. Inventory counts homes changing hands, the same units getting resold. Permits count homes coming into existence, brand new units. This year those two numbers went in opposite directions. Listings went up. Permits fell off a cliff.

Boston issued building permits for just 432 housing units in the first quarter of 2026. That is down from 549 in the same quarter of 2025 and 642 in 2024, and it puts the city on pace for its slowest construction year since 2010, the depths of the Great Recession. So here is the read I am giving my clients. The tank of existing homes is being opened for the first time in years. The tap that refills it is closing. Those are not the same story, and confusing them is how you make a bad decision in this market.

What Boston’s permit numbers actually say

Start with the city itself. A building permit is the first real step before anything gets built, so it is the earliest signal we have about how much new housing is actually on the way. In Boston that signal is flashing red.

Permits for 432 units in a quarter is not a small dip off a healthy baseline. Through the 2010s and up until 2022, Boston typically permitted 3,000 to 4,000 units a year. In 2024 the city permitted 2,219, the fewest since 2012. The first quarter of 2026 came in more than 20 percent below the same quarter a year earlier, and roughly a third below where it was two years ago.

The important part is what a permit represents. It is not a finished condo you can buy this month. It is a unit that, if it gets financed and built, shows up two or three years from now. So the 432 number is not describing today’s market. It is describing the supply Boston will or will not have in 2028 and 2029.

This is not just a Boston story

If it were just the city, you could wave it off as Boston being Boston, with its permitting process and its politics. It is not just the city.

Across Greater Boston, permits fell from 15,019 in 2021 to just under 9,000 in 2024, a drop of roughly 40 percent, according to the 2025 Greater Boston Housing Report Card from the Boston Foundation. Statewide, Massachusetts fell from a peak near 20,000 permits in 2021 to just over 14,000 in 2024. As of July 2025, new permits were running 44 percent below the same stretch of 2021.

The sharpest version of the story is in the urban core. The Metropolitan Area Planning Council tracks the 17 Metro Mayors cities that ring and include Boston, from Somerville and Cambridge to Quincy and Revere. Those communities permitted 4,755 units in 2024, the lowest in nearly a decade of tracking and down about 60 percent from the 2022 peak of 11,658. To hit their own 2030 housing goal, those cities need to permit roughly 12,333 units a year. They are running at a bit more than a third of that.

One honest note on the numbers, because I would rather be straight with you than hand you a scary headline. You will see a “67 percent” decline quoted around this topic. That figure comes from mixing two different maps, the wider Greater Boston count for 2021 against the smaller 17-city count for 2024. The real declines are steep enough on their own, about 40 percent regionally and about 60 percent in the core. There is no need to inflate them.

Where this year’s “new” supply is actually coming from

So if almost nothing is being built, where did the extra listings come from? Existing owners. For three years, most people holding a mortgage in the 2 or 3 percent range simply refused to sell, because moving meant trading that rate for something near 7. That is the rate-lock effect, and it froze a huge share of normal turnover.

That freeze is finally thawing. By 2026, for the first time, there are more homeowners with a rate above 6 percent than below 3, and the 30-year fixed has settled into the mid 6s rather than spiking further. Life keeps happening, jobs change, households change, and more owners have decided they can no longer wait. The result showed up in the spring numbers. Active listings across the Boston market were up about 10 percent year over year at mid-2026, new condo listings rose even faster, and homes took a little longer to sell, with the share going for over asking sliding to about 41 percent.

Read that carefully. Every one of those extra listings is a home that already existed. Reselling a triple-decker in Dorchester does not put a roof over anyone new. It just changes whose name is on the deed. That is the difference between stock and flow, and it is the whole point.

Why builders stopped, and why both sides are half right

City officials have a name for this. They call it the Big Chill. What they cannot agree on is the cause, and that argument tells you a lot about where the market goes next.

Developers and the industry groups point at City Hall. Greg Vasil, who runs the Greater Boston Real Estate Board, and Tamara Small, the CEO of the developer group NAIOP Massachusetts, argue the city’s own policies are much bigger factors than the Wu administration will concede. Their list is specific. Boston adopted a stricter net-zero energy code in 2023 that took effect at the start of 2024 and raises the cost of new construction. The affordable set-aside on new projects rose from 13 percent to as much as 20 percent, with deeper affordability, on buildings of seven units or more. The mayor has a live home-rule petition for a 2 percent transfer fee on the portion of any sale above 2 million dollars. And a rent-control question is headed for the 2026 ballot. Every one of those raises the cost or the risk of building here.

City Hall points at the wider economy. Interest rates sit far above their 2010s levels, tariffs have pushed up the price of materials, labor is tight and more expensive, and inflation never fully returned to where it was before 2022. All of that is also true.

Here is what I tell people who ask me to pick a side. For your decision, it does not matter. Whether it is policy, or macro forces, or more honestly both at once, the outcome is identical. The pipeline that normally refills Boston’s housing supply a few years out is drying up right now.

Why a permit slump today is a shortage in 2028

This is the part that turns a dry statistic into a real forecast. Permits lead construction, and construction leads move-in, usually by two to three years for anything larger than a single house. So the permits a city pulls this year are a preview of the homes it will hand over near the end of the decade.

Massachusetts already knows how big the hole is. The state’s own housing plan says we need about 222,000 additional units by 2035 just to catch up and keep costs from running away. Greater Boston is not permitting anywhere near its share of that. When the urban core permits a third of what it needs, it is not closing the gap, it is widening it. You will feel the result in a few years, as the current wave of resale listings clears and very little new arrives behind it.

That is why “more listings today” and “more housing tomorrow” are not the same sentence. One is this year’s thaw. The other requires a shovel in the ground, and the permit data says the shovels are sitting still.

If you are buying: treat the room you have as a window

I am not telling buyers to sit out. I am telling them to read the clock correctly. The negotiating room you are getting this year in places like South Boston and East Boston is real, and it is worth using. Sellers are more willing to talk, inspections are less of a formality, and you are not always up against five other offers.

Just do not assume it is permanent. This leverage is tied to a one-time surge of existing owners listing, not to a stream of new buildings adding options every month. There is very little new small-multifamily or mid-rise construction coming in behind these listings. The most realistic source of small-scale new supply is the accessory dwelling unit, and those trickle in slowly. Once this year’s backlog of listings sells through, the same shortage that defined 2022 and 2023 is still sitting underneath the market. If you find the right home now, the softer terms are a gift. Waiting two years for a flood of new construction that the permit numbers say is not coming is a poor bet. If you want to pressure-test a specific neighborhood before you commit, that is exactly the kind of thing we walk buyers through.

If you are selling: well-located triple-deckers still hold the cards

The rising-inventory headlines make some sellers nervous. For most of the sellers I work with, especially owners of well-located two and three-family homes in neighborhoods like Dorchester and Jamaica Plain, the underlying position is still strong, and the permit data is the reason.

Think about what a buyer’s alternatives actually are. They cannot go buy the new-construction version of your triple-decker down the street, because it is not being built. Almost nothing new is competing with you. That scarcity is exactly why the classic Boston housing stock holds its value even in a year when listings tick up. What has changed is the margin for error. Homes are taking a bit longer to sell and fewer are going over asking, so the price-it-high-and-wait approach that worked in 2022 will cost you now. Price it to this market, present it well, and the scarcity does the rest. If you want a grounded read on what your specific property is worth today, start with a real home valuation rather than a two-year-old comp.

If you are investing: the permit collapse is the signal

For investors the permit data is not a warning, it is the thesis. When new supply dries up in a region that is still short hundreds of thousands of units, the existing stock becomes more valuable, not less. The replacement cost of building a new multifamily in Boston is climbing because of the same energy code, set-asides, tariffs, and labor costs that stalled construction in the first place. That puts a rising floor under the buildings that already exist.

So I would rather own a solid existing three-family in a strong location than bet on a new-build pro forma that has to survive Boston’s permitting, its policy fights, and a rent-control question on the ballot. The scarcity that squeezes buyers and renters is the same scarcity that rewards owners of well-placed existing multifamily property. Read the collapse in permits as the market telling you where the competition is not going to be.

What I would tell you in one line, and the number I am watching

Strip away the noise and it comes down to this. To a buyer: use the window, do not wait for it to become a new normal, because the construction that would make it permanent is not being permitted. To a seller of a well-located home: you still hold the stronger hand, just price it to a market with a little more patience than it had two years ago. To an investor: scarcity is the trade, and the permit numbers just told you how scarce it is about to get.

The one number I am watching is the next quarter of Boston permits, alongside what the State House does with the transfer fee and the rent-control ballot. If permitting keeps sliding, everything above only gets more true. If it turns, we will have the first real evidence that the pipeline is refilling. Until then, I read this year’s extra listings for exactly what they are, a thaw in who is selling, not a change in how much is being built.
