August 2026 Greater Boston Market Update + Cambridge Zoning Changes

The Greater Boston real estate market is giving buyers something they have not had much of in recent years: more options.

In our August episode of Bridging the Market, Hudson Santana and Emily break down what we are seeing across Cambridge, Somerville, Arlington, and Medford as summer winds down. We also dig into one of the biggest changes affecting Cambridge real estate right now: the city's new multifamily zoning rules and what they could mean for homeowners and investors.

August Market Update: Inventory Is Up 27%

At the time we recorded this episode, the number of active listings across our core Greater Boston market was 27% higher than it was on the same day last year.

For buyers, that matters. More inventory means more choices and, in some cases, more negotiating room.

For sellers, the same trend means more competition. When buyers have several comparable properties to choose from, pricing, preparation, condition, and presentation become even more important.

A home does not simply need to be available. It needs to stand out against the other choices buyers have.

Why Are More Homes Coming on the Market?

There is no single explanation, but one trend we are beginning to see involves homeowners who purchased or refinanced when mortgage rates were exceptionally low.

Many have delayed moving because they understandably did not want to give up those rates. Eventually, though, life can outweigh the mortgage.

People need more space, less space, a different location, or simply a home that better fits their needs today. Some homeowners who spent the last few years staying put are beginning to make those moves.

We are also starting to see additional housing created as a result of zoning changes in communities like Cambridge and Somerville.

Late Summer Can Create Opportunities for Buyers

By August, buyers who started searching in the spring may have already spent months attending open houses, watching new listings, and competing for homes.

Some decide to renew a lease or pause their search until the following year.

For the buyers who stay active, that seasonal slowdown can create opportunity.

This year, fewer late-summer buyers are shopping at the same time that inventory is higher than it was last year. Properties that have been sitting on the market may offer more room for negotiation than they would have during the busiest part of the spring market.

That does not mean every property is suddenly a bargain. Well-priced homes can still attract significant interest.

But if you have not found the right home yet, late summer may be a reason to stay in the market rather than automatically waiting until next spring.

What Should Sellers Be Thinking About?

More inventory makes positioning especially important.

If a property has been sitting on the market without selling, we generally look at three things:

Price

Is the home priced based on what buyers are actually willing to pay today?

Condition and Presentation

What feedback are buyers giving? Are there repairs, staging changes, updates, or presentation issues that could make the property more competitive?

Timing

Does the seller need to move now, or do they have the flexibility to pause, make adjustments, and potentially relaunch later?

There is no universal answer. The right strategy depends on the property, its competition, and the seller's goals.

Cambridge's New Multifamily Zoning: What Changed?

In February 2025, Cambridge adopted major zoning changes that allow multifamily housing citywide.

Residential neighborhoods that previously had different and sometimes more restrictive rules are now generally zoned Residence C-1.

Residence C-1 allows residential buildings up to four stories. Projects that meet Cambridge's inclusionary housing requirements and other criteria may be permitted up to six stories.

The city also eliminated zoning limits on minimum lot size, maximum unit count, and maximum residential floor area. Setback, open-space, building-code, historic-review, and other requirements still apply.

So no, every Cambridge single-family house did not magically become a nine-unit condo building overnight.

But many properties may have significantly different development potential than they did before the zoning change.

You can read more about the changes directly on the official City of Cambridge multifamily zoning page .

Why Cambridge Homeowners Should Pay Attention

The zoning changes matter even if you have absolutely no intention of developing your property yourself.

Consider a single-family home in Cambridge.

Historically, the most obvious buyer may have been someone looking specifically for a single-family home. Today, depending on the lot and location, builders and investors may also be evaluating what else could potentially be built there.

That changes how the property should be analyzed.

In addition to the existing home's size, condition, bedrooms, bathrooms, and comparable sales, we may need to look at:

• Lot size and configuration
• Zoning and setbacks
• Open-space requirements
• Potential building size and unit count
• Existing structure and historic considerations
• Construction and permitting constraints

The Santana Team has helped 500+ clients since 2014 throughout Greater Boston, including extensive work with builders, investors, new construction, and development properties.

When zoning changes a property's potential use, we look beyond a traditional comparative market analysis to understand the options before advising an owner on value or strategy.

What Happens With Larger Cambridge Developments?

Cambridge's Inclusionary Housing Program generally applies when a residential development creates 10 or more units or more than 10,000 square feet of residential space.

Those developments are generally required to devote 20% of their residential floor area to affordable units.

That threshold can significantly affect the feasibility of a project, which is one reason determining what a Cambridge property may be worth to a builder requires more analysis than simply calculating how many units could fit on a lot.

Somerville Backyard Cottages and ADUs Are Not Necessarily the Same Thing

We also tackled a common source of confusion in the episode: backyard cottages and accessory dwelling units, or ADUs.

Massachusetts law expanded opportunities for ADUs statewide, while Somerville has its own locally defined Backyard Cottage building type within its zoning.

The terminology and regulations can overlap, but they are not interchangeable in every situation. Somerville's zoning provisions have also continued to evolve.

If you are thinking about adding a unit, converting a structure, or evaluating a property's development potential, verify the current rules for that specific property before assuming what can be built or how it can be owned.

Property Spotlight: 37 Kingston Street Unit A in Somerville

We wrapped up the episode with a property Hudson considers one of the standout opportunities currently on the Somerville real estate market:

37 Kingston Street Unit A in Somerville .

Currently offered at $1,049,000, the new-construction home offers 3 bedrooms, 3 bathrooms, and approximately 1,827 square feet.

One of its biggest draws is location. Kingston Street is tucked on a residential street near Davis Square, close to the Cambridge line and convenient to Mass Ave, the Red Line, shops, restaurants, and other neighborhood amenities.

For buyers who want the feel of a newer home while staying close to Cambridge and Davis Square, it is a good example of the additional choices available in today's Somerville market.

Listing price and availability are subject to change.

Frequently Asked Questions

How did Cambridge zoning change in 2025?

Cambridge changed its zoning in February 2025 to allow multifamily housing citywide. Residential neighborhoods that previously had different zoning restrictions are now generally governed by Residence C-1 zoning, which allows residential buildings up to four stories, with additional height possible for qualifying inclusionary housing projects.

Can every Cambridge single-family home now become a multifamily development?

No. The zoning allows multifamily housing citywide, but a property's actual development potential still depends on its lot configuration, setbacks, open-space requirements, historic considerations, building codes, permitting requirements, and other site-specific factors.

Is a Somerville backyard cottage the same as a Massachusetts ADU?

Not necessarily. Massachusetts ADU law and Somerville's local Backyard Cottage zoning provisions have different definitions and requirements. Owners should verify the current rules for their specific property before planning an addition or development.

What Does This Mean for Your Next Move?

For buyers, higher inventory combined with the normal late-summer slowdown may create opportunities worth watching.

For sellers, more competition means pricing and preparation matter even more.

And for Cambridge homeowners, recent zoning changes may have changed not only what can potentially be built on a property, but also who may be interested in buying it.

Those decisions should involve more than an automated valuation and a quick look at a zoning map. We look at the property, current market, development potential, and owner's goals before recommending a strategy.

Because we work as a full team, our clients also have support throughout the buying, selling, investment, listing, marketing, and closing process.

Market statistics, listing availability, zoning regulations, and municipal requirements change over time. Information in this article reflects the market and rules discussed in August 2026 and is provided for general informational purposes. Property owners should verify current requirements with the applicable municipality and qualified legal, zoning, design, or construction professionals before making decisions based on development potential.
