Construction of buildings with five units or more, which tends to be volatile month-to-month -- gave the overall number a big boost when that category alone surged 80% in January.

Meanwhile, the number of permits for future housing construction fell to an annual rate of 562,000 last month, down 10.4% from 627,000 in December, the Commerce Department said.
The reading fell short of forecasts, with economists surveyed by Briefing.com looking for 575,000 permits.
The decline comes after a very strong December, when permits reached their strongest level since last March.
