About the Affordable Housing Trust Fund

The Somerville Affordable Housing Trust Fund (SAHTF) was created in 1989 by a City ordinance to preserve and create affordable rental and homeownership units in Somerville, and to carry out programs to directly assist homeowners and renters. All of its activities must benefit low-to-moderate-income households (with incomes at or below 110% of area median income). In 2023, the Trust completed a Strategic Visioning process to produce a new Strategic Plan and updated guidelines, which are available to view by clicking the link below:

Linkage Fees and Revenue All linkage fees from commercial development in Somerville go to the Trust, as do fractional payments made pursuant to the City's Inclusionary Zoning Ordinance. The Trust also receives revenues from the repayment of Trust-funded loans to affordable housing developers, first-time homebuyers, or other loans.
