US construction spending rose slightly in March, fuelled by increases for apartments, single-family homes, factories, health care centres and office projects.
The Commerce Department said that construction spending increased just 0.2 per cent in March, after having fallen 0.2 per cent in February.
The March gains put construction at a seasonally adjusted annual rate of $US942.5 billion ($A1.02 trillion), an 8.4 per cent increase year-over-year.
Construction spending dipped in January with the harsh winter weather and continues to run below its December 2013 levels.
Apartment construction spending increased 4.3 per cent in March, while single-family home spending inched up 0.2 per cent. Residential construction spending is at its strongest pace since May 2008, nearly five years ago.
Spending on government projects fell 0.6 per cent, including a 2.3 per cent drop for schools and educational buildings.
Despite the gains in residential construction, warmer weather has yet to produce much of a rebound for residential real estate.
Builders started work on 946,000 homes at a seasonally adjusted annual rate in March, up 2.8 per cent from 920,000 in February, the Commerce Department said last month.
Applications for permits, a gauge of future activity, fell 2.4 per cent to a seasonally adjusted annual rate of 990,000.
Sales of new homes declined 14.5 per cent in March to a seasonally adjusted annual rate of 384,000, the second straight monthly decline and the lowest rate since July 2013. Sales have declined 13.3 per cent over the past 12 months.
New-home buying plunged in the Midwest, South and West in March. But they picked up in the Northeast, where snowstorms in previous months curtailed purchases.
The National Association of Home Builders/Wells Fargo builder sentiment index was 47 in April. Readings below 50 indicate that more builders view sales conditions as poor rather than good.
Sales have also been modest because of affordability issues as rising prices over the past year and higher mortgage rates have made it harder for many Americans to afford a home.
