WASHINGTON, Feb 27 (Reuters) – U.S. construction spending increased in December, lifted by a rebound in single-family homebuilding ‌as well as ongoing strength in home renovations.

The Commerce ‌Department’s Census Bureau said on Friday that construction spending rose 0.3% after ​falling 0.2% in November. The increase was in line with economists’ expectations. Construction spending slipped 0.4% year-on-year in December. The data was delayed by last year’s government shutdown.

Spending on private ‌construction projects rose 0.5% ⁠in December after easing 0.2% in November. Investment in residential construction increased 1.5% after being unchanged ⁠in November. Spending on new single-family housing projects rebounded 1.5%. Spending on multi-family housing units, which account for a small ​share of ​the housing market, rose 0.1%.

Renovations ​increased further. Despite December’s ‌acceleration, homebuilding remained sluggish amid higher mortgage rates, more expensive building materials because of tariffs on imports, and labor shortages.

A decline in mortgage rates in recent weeks could spur construction, though building lots remain scarce. Residential investment has declined for ‌four straight quarters.

Spending on private ​nonresidential structures like offices and factories ​dropped 0.7% in December. ​Spending on nonresidential structures has contracted for eight ‌consecutive quarters, despite a surge ​in the construction ​of data centers to support artificial intelligence.

Investment in public construction projects decreased 0.5% after falling 0.2% in November. ​State and local ‌government construction spending declined 0.7% in December, but outlays ​on federal government projects increased 1.6%.
