Chelsea Restoration Corporation is among six agencies statewide that were recently awarded federal grants to provide housing counseling services to low- and moderate-income people. The Chelsea nonprofit, which works to help families obtain affordable housing, plans to use the $15,214 to continue providing training in English and Spanish to first-time home buyers on steps needed to purchase a home. The training includes talks by attorneys, bankers, real estate agents, and home inspectors, according to Helen Zucco, executive director of Chelsea Restoration Corporation. “We are very pleased to receive funding again for this affordable housing training,,” Zucco said, noting that this is the third year that her agency has received the grant. The grant was among $99,036 allotted to Massachusetts organizations and $40 million awarded nationwide by the US Department of Housing and Urban Development.
