On September 23, 2026, the American Institute of Architects reported that architecture firms are still experiencing soft business conditions. According to the August AIA/Deltek Architecture Billings Index (ABI), the industry recorded a score of 47.2, signaling a continued downward trend despite a slight improvement in the number of firms noting declining billings compared to the previous month.
The findings from the report highlight a difficult environment for design professionals as demand remains fragile. While inquiries regarding potential new projects showed modest growth, sign-ups for new design contracts kept falling. This cooling demand is reflected in the growing pessimism among firm leaders. Data shows that 29 percent of firms expect a decline in billings for the third quarter. This is up from 21 percent in the first quarter.
Regional results for August offered a mixed outlook. The Midwest experienced a shift with modest growth, marking its first increase in nearly a year, while firms in the West reported nearly flat performance. Conversely, the Northeast region faced a significant downturn, with billings reaching their lowest point since 2020.
Economic factors are compounding these operational challenges. Although the sector added 700 jobs in July, inflation remains a persistent issue. The Consumer Price Index (CPI) rose by 0.4 percent in August, following a 0.1 percent increase in July. This contributes to a 3.4 percent year-over-year rise, largely driven by energy and gasoline costs. AIA Chief Economist Richard Branch noted that the industry is currently squeezed between inflationary pressures and the burden of higher borrowing costs.
Sector-specific performance varied, with commercial and industrial projects posting a 50.4 score. Other categories saw lower activity, including multifamily residential at 47.8, institutional at 47.0, and mixed practice firms at 42.5. For underwriters and insurance professionals, these figures highlight a period of increased risk within the design and construction space. Firms are grappling with project delays and financing hurdles. Insurers should monitor professional liability exposure, as economic uncertainty often leads to more claims in the architectural and engineering sectors.
