Brookline is compliant with the MBTA Communities Act. The town adopted zoning that meets the state's multifamily requirement near its rapid transit stations on the Green Line, and the state has determined Brookline compliant per the EOHLC approval list. The state required Brookline to zone for a capacity of 6,990 units. For owners and investors, it can expand what you are allowed to build on a Brookline parcel near transit.
What is Brookline's MBTA 3A zoning?
Brookline meets the MBTA Communities Act through zoning that allows multifamily housing by right near its rapid transit stations on the Green Line, which the state's Executive Office of Housing and Livable Communities has determined compliant. As a rapid transit community, Brookline was required to zone for a capacity of 6,990 multifamily units, equal to 25 percent of its housing stock. The zoning means qualifying projects no longer need a special permit in eligible areas near Brookline's rapid transit stations.
Which parts of Brookline are in the district?
The Brookline district focuses on parcels near its rapid transit stations on the Green Line, including Coolidge Corner, Brookline Village, and Brookline Hills. Because the boundaries are parcel specific and some lots are excluded, the only reliable way to know if a given property is in the district is to check it against the town's adopted zoning map. Send us the address and we will look it up.
What can you build under it?
Inside the Brookline district, multifamily housing is allowed by right at the densities the district sets, at a minimum of 15 dwelling units per acre. That can turn a parcel that previously allowed only a single home or a two family into one where a multifamily building is permitted without a special permit. The exact unit count depends on the lot and the district rules, so each parcel needs its own analysis.
What does this mean for Brookline owners and investors?
If your parcel sits in the Brookline district, your development potential and therefore your value may be higher than the old zoning implied. For investors, Brookline's by right multifamily potential represents an opportunity in one of the strongest rapid transit markets on the corridor. For sellers, it is worth knowing whether your lot carries this upside before you price it, since it can change what a buyer will pay. For owners holding long term, the added development rights can sit on your balance sheet as future optionality. We run that analysis before clients buy, sell, or hold.

How do I find out if my Brookline property qualifies?
Send us the address and we will confirm whether it falls in the district and what that allows, usually the same day. Or check it yourself against the town's adopted zoning map and look up whether your parcel is inside a district boundary.
