WASHINGTON – Construction of new homes jumped in May by the largest amount in three months, an encouraging sign that the nation's deep housing recession was beginning to bottom out.

The Commerce Department said Tuesday that construction of new homes and apartments jumped 17.2 percent last month to a seasonally adjusted annual rate of 532,000 units. That was better than the 500,000-unit pace that economists had expected and came after construction fell in April to a record low of 454,000 units.

In another encouraging sign, applications for building permits, seen as a good indicator of future activity, rose 4 percent in May to an annual rate of 518,000 units.
