U.S. builders started work on more single-family homes in May and requested the most permits to build homes and apartments in 31/2 years.
The increase suggests the housing market is slowly recovering even as other areas of the economy have weakened.
The Commerce Department said Tuesday that builders broke ground on 3.2 percent more single-family homes in May, the third straight monthly increase.
Overall housing starts fell 4.8 percent last month to a seasonally adjusted annual rate of 708,000. But that decline was entirely because of a 21.3 percent plunge in apartment construction, which can be volatile from month to month.
The government also said April was much better for housing starts than first thought. The government revised the April starts to 744,000 -- up from an initially reported 717,000 and the fastest building pace since October 2008.
And builders are more optimistic about the next 12 months. They requested more permits to build homes, a gauge of future construction. Permits increased to a seasonally adjusted rate of 780,000 -- the most since September 2008.
Even with the gains, the rate of construction and the level of permits requested remain roughly half the pace considered healthy.
Yet, the increases add to other signs that the home market may finally be starting to recover nearly five years after the housing bubble burst.
Builders have grown more confident since last fall, in part because more people are expressing an interest in buying a home. Cheaper mortgages and lower home prices in many markets have made home buying more attractive.
Many economists believe that housing construction could contribute to overall economic growth this year for the first time since 2005.
By region of the country, housing starts rose 14.4 percent in the West but dropped in other parts of the country.
The declines primarily reflected the weakness in apartment activity.
