The former first daughter visited locations in Far Rockaway, Queens and on Staten Island.
Clinton helped the Lyons family hammer nails into a piece of siding at what will be the family's new home in Far Rockaway.
The family of five was in Brooklyn when Sandy hit.
When the family returned home a few days later their house completely destroyed, said Lintia Duncan-Lyons, a mother of five. "It was horrible, everything in the house was devastated," she said.
The new house is being built by the New Orleans-based St. Bernard Project with various partners that met through the Clinton Global Initiative.
St. Bernard held a competition for architects to design a "resilient" house for the area.
Duncan-Lyons said she can't wait for the house to be completed.
Construction is expected to be completed in July.
Clinton said she was thrilled that the family would get a home that is safe, secure, beautiful and affordable.
Saturday was the second Sandy-related "Day of Action" the Clinton Foundation has sponsored, working with thousands of volunteers.
