Much of the Commonwealth's stock of affordable housing units was built in the 1960, 1970s and 1980’s. These projects now face the elimination of restrictions that they serve low-income residents due to the potential for owners to prepay their federally-subsidized mortgages, or opt out of their existing Section 8 rental subsidy contracts. To preserve these units requires a combination of resident and community initiative, public and private investment, and technical expertise.

CEDAC works with federal and state agencies to coordinate housing policies that promote the preservation of these existing affordable housing communities.  CEDAC helps community organizations and municipalities leverage the resources they need to prevent these valuable housing units from being lost by helping negotiate the extension of current affordability restrictions or the sale of such projects to non-profit owners; securing new capital investment to meet deferred maintenance or systems replacement needs; and advocating for public policy which supports such outcomes. Given the high costs of new production, preventing the loss of existing affordable housing is a high priority for CEDAC.

In 2009, Massachusetts was selected by the John D. and Catherine T. MacArthur Foundation as a grantee in the State and Local Housing Preservation Leaders program with CEDAC as the lead agency.  Click here for more information.

Expiring Use Properties in Massachusetts

CEDAC maintains a database of over 125,000 housing units in 1,470 projects located throughout the state.  These properties are privately owned but were produced using state and/or federal housing resources.  Most funding programs required that owners commit to maintaining the properties for a particular period of time – typically 20 to 40 years.  CEDAC uses this database of affordable housing projects to identify when specific projects are eligible to end affordability restrictions and convert to market rate housing.  Periodically CEDAC posts summary reports on the affordable housing stock.

Chapter 40T – An Act Preserving Publicly Assisted Affordable Housing
On November 23, 2009, the Governor signed Massachusetts General Law Chapter 40T – An Act Preserving Publicly Assisted Affordable Housing. This landmark legislation aims to help preserve existing privately-owned affordable housing in Massachusetts. The legislation establishes notification provisions for tenants, a right of first refusal for DHCD or its designee to purchase publicly assisted housing, and modest tenant protections for projects with affordability restrictions that terminate.

“Since Chapter 40T was enacted in 2009, no project has lost affordability as a result of a sale.”
