The latest quarterly cost report (QCR) charts construction trends in 16 cities throughout North America (formerly 14; Miami and Nashville have been newly added). The latest report indicates that construction costs are slowing down.

With data current to mid-Q1 2025, shows that the national average change in construction costs was 0.98% in Q1, which was down from 1.11% in Q4; congruently, the year-over-year rate is 4.35%, down from 5.86% this time last year. Boston, Chicago, Honolulu, Portland, and Seattle experienced increases in construction costs over the national average this quarter, while Denver, Las Vegas, Los Angeles, Nashville, Miami, Phoenix, San Francisco, and Washington D.C. experienced gains that were less than the national average. 

  • The U.S. national average increase in construction cost is approximately 0.98 percent in Q1, compared to 1.11 percent in Q4
  • The construction unemployment rate is 5.4 percent, down from 5.7 percent during the same period last year
  • The Architectural Billings Index (ABI) in January was 45.6, a slight increase from 44.6 in December
