New York Mayor Michael Bloomberg says about 20,000 of those needing temporary housing are public housing residents, Reuters reported.
Around 1.9 million homes and businesses in the Northeast remain without power on Sunday morning, down from 2.5 million on Saturday afternoon, the US Department's Office of Electricity Delivery & Energy Reliability said in a report.
New Jersey and New York accounted for nearly 90 per cent of the remaining power cuts.
New York Mayor Michael Bloomberg said the city authorities' focus was on providing shelters for the homeless amid cold weather:
Our focus today is checking in on people & seeing who else needs a warm place to sleep tonight. Shelters are open http://t.co/pRh2iWS4
British comedian Ricky Gervais said some New York Marathon runners are doing the event despite it being cancelled:
In Central Park watching all the runners just doing the marathon anyway. Brilliant. Hope everyone who sponsored for charity still pays up.
Hundreds of runners in New York City are refusing to let a cancelled marathon spoil their Sunday plans and are channelling months of preparation into informal runs intended to benefit victims of superstorm Sandy.
More than 1,000 people, many of whom had planned to run the race, crowded onto two Staten Island Ferry boats with relief supplies for the stricken borough.
Meanwhile on Sunday morning, Central Park was crowded with runners on near what would have been the marathon's finish line, many collecting donations for Sandy victims.
New York Governor Andrew Cuomo is encouraging people to make donations for the victims of Hurricane Sandy. He advises individuals to donate money and suggests large corporations provide useful products.
New York Mayor Michael Bloomberg said following Hurricane Sandy the sanitation department had made "enormous progress" and was working round-the-clock.
Tens of thousands of people affected by superstorm Sandy could soon need housing as cold weather hits the state of New York, Governor Andrew Cuomo has said.
Cuomo said in a TV press conference almost a week after the storm hit the US East Coast that the fuel shortages are getting better but difficulties will persist for "a number of days."
New York Mayor Michael Bloomberg said there are as many as 30,000 to 40,000 people in the city that "we have to find housing for" in the wake of storm Sandy.
