Boston's Triple Decker Campaign

Boston’s triple decker campaign, the 3D Program, is committed to preserving and celebrating this quintessentially Boston housing style.


Boston's Triple Deckers

Boston has almost 9,000 triple deckers, housing that first began appearing in Boston’s neighborhoods in the 1890’s but still provide livable, affordable homes for Bostonians in the 2010’s.  If you’re already an owner of a triple-decker or a condominium unit within one, we want to help you celebrate the versatility and longevity of these fantastic properties. If you’re looking to buy and restore a triple decker, we can help you with that, too. 


The 3D Program

The 3D Program offers a wide range of benefits and services to help owners of Triple Deckers make the most of their properties. There are also services to help you buy a Triple Decker of your own. From discounts at hardware stores, to workshops on how to find a good contactor, to zero-percent loans for home improvements and energy conservation, to downpayment assistance for first-time homebuyers, to a house painting contest celebrating the best in 3D homeownership, the 3D Program represents an unprecedented commitment by the City of Boston to recognize and renew this iconic housing form.

  • Boston Public Improvement Commission Hearings 4-16-15
    The Boston Public Improvement Commission (PIC) is the owner and regulator of the City's rights of way. The PIC plays an integral role in the City's development and permitting process. From the restaurant that wants to add a seasonal cafe on the public sidewalk, to the developer who wants to construct an underground parking garage for a new housing development, or the homeowner who wants to add an architectural feature to a house that juts into the public space, each must seek approval from the PIC to have its private venture occupy public space, either permanently or on a licensed basis.Watch Video »
