Where Zoning Ends and Housing Begins in Greater Boston's Suburbs

Greater Boston has plenty of opportunity to build housing. What it doesn’t have is housing.

A convergence of record construction costs, a state mandate forcing municipalities to rezone near transit, and deeply entrenched local resistance to density has exposed just how wide the gap can be between what the law permits and what the market can deliver. In the inner western suburbs – where biotech growth, transit access, and small-town politics intersect daily – that dynamic is playing out across five distinct communities. The results are uneven at best.

Max Woolf, Public Policy and Government Affairs Manager at the Charles River Regional Chamber, sits at the center of this dynamic. Representing Brookline, Watertown, Newton, Needham, and Wellesley, the chamber advocates for the business community across planning boards, city councils, and select boards where housing decisions are made.

The stakes are concrete: high costs and restricted supply are making it harder for workers to relocate and harder for local businesses to attract foot traffic. “Housing is our number one economic development issue in Massachusetts,” Woolf notes.

Rezoning vs. Reality

One of the clearest illustrations of the region’s housing challenge is the difference between theoretical capacity and actual production. When Needham completed its rezoning plan under the state’s MBTA Communities Act, the headline figure suggested roughly 3,000 new units could be unlocked. Woolf’s analysis told a different story.

Zoning changes alter what is legally allowed to be built, but not what will actually be built. Given current interest rates, construction costs, and the limited number of parcels that can realistically be redeveloped, the chamber’s projection was closer to 1,000 units over a decade. The final plan, after community pushback scaled it back further, is now projected to yield around 400 units over ten years. According to Woolf, even that number is “optimistic.”

This disconnect matters not just for housing advocates, but for developers and investors trying to assess where opportunity actually exists.

Development Obstacles

When projects stall or die entirely, the reasons are rarely simple. Financing is the most immediate barrier. Massachusetts construction costs run roughly 13 percent above the national average, and Boston consistently ranks among the most expensive cities to build in the country. That cost floor makes it hard for developers to demonstrate sufficient profit margins to secure bank loans at current interest rates. Many projects simply don’t pencil out

Timelines compound the problem. In Massachusetts, multifamily projects routinely take two or more years to move from permit to completion, and that’s after clearing local approval processes that can themselves stretch for years. Layered on top are Massachusetts-specific affordability set-asides, the state’s Stretch Energy Code – among the most demanding building energy standards in the country – tariffs on wood and steel, and the general unpredictability of community approval processes. “It’s really all factors that are increasing the cost of housing and making projects not pencil,” Woolf says.

The result is a market that has been largely quiet on new construction starts. Projects permitted before or during the pandemic are still being built, but fresh investment activity across the five communities has slowed considerably.

A Mixed Record

The MBTA Communities Act is the most significant housing policy intervention in recent memory for this region. Its impact, however, has varied widely depending on how seriously each community engaged with the mandate.

Watertown stands out as a genuine success. The city aggressively rezoned its downtown, embraced by-right permitting, which removes the need for discretionary approval on compliant projects, and has paired its commercial growth, particularly in biotech, with meaningful residential development. “Watertown’s done a great job of pairing their commercial development with residential development, giving their workers a place to stay and really embracing growth,” Woolf observes.

Other communities took a more defensive approach, rezoning parcels that had already been developed or that carried physical constraints, making redevelopment unlikely. Woolf expects change in those places to come much more slowly. Across all five towns, one area remained largely untouched: single-family neighborhoods, which make up the majority of the region’s residential land. “That’s kind of the next frontier – how do we unlock more density in our single-family neighborhoods?” he says.

Successful Projects

Despite the difficult environment, some significant projects have cleared the bar. Two large residential developments in Newton – one near the Charles River totaling close to 900 units, the other a roughly 700-unit project near a Boston transit line – represent the kind of scale that can genuinely transform a neighborhood’s housing options. Both faced long approval processes and required permit revisions as market conditions changed. One has already broken ground.

“They’re examples of really exceptional proposals that didn’t initially have the broadest community support, but through a marathon of public process, sometimes spanning a decade, finally passed the finish line,” Woolf says.

What made the difference in cases like these often comes down to the business community showing up. When a restaurant owner or retailer speaks at a public hearing about how a nearby housing project would bring more customers through the door, or shorten employee commutes, it changes the conversation. That kind of testimony carries weight with local leaders and can move decisions on whether a project or rezoning gets approved.

Suburban Misconceptions

One of the most persistent obstacles to housing growth in the region is the fear that adding density will mean losing community character. Woolf directly pushes back on that framing. “A lot of our suburban communities say we don’t want to be Boston, but I think that misses the point. We’re never going to be Boston out here.”

The more relevant question, he says, is whether the small village centers and local businesses that residents value can survive without more nearby customers and workers. The small shops that residents frequent in their downtowns depend on foot traffic to remain viable, and the businesses that employ local workers need those workers to live within a reasonable distance. Resisting growth does not preserve what people love about these communities – it undermines it.

What to Watch

Near-term change at the local level is likely to remain incremental. Each community moves at its own pace, shaped by its own political dynamics. Woolf does not expect the next six months to produce major movement.

The more meaningful signals will come from state and federal policy. With growing bipartisan consensus around housing reform and legislative activity at both levels, Woolf sees a realistic window over the next two to three years for policy changes that push more authority toward regional bodies and create stronger incentives – or requirements – for communities to build. “If we want real regional change,” he says, “it has to come from the state or the federal government.”

For investors and developers tracking the Boston suburbs, the practical takeaway is that the policy environment is loosening, but slowly and unevenly. The communities that have already streamlined their processes and embraced growth are the ones where projects are moving. The rest are still working through the gap between what the zoning map says and what the market can actually deliver.
