Architecture Billings Posted Modest Decline in July to 46.6

Washington, DC, August 19, 2026—The AIA/Deltek Architecture Billings Index (ABI) score for July was 46.6, signaling a modest decline from June’s 47.3.

This ongoing slump in business conditions has now stretched to nearly three and a half years, the longest in the ABI’s history. Clients continue to show interest, as inquiries for new projects rose again in July, though more slowly than in June. At the same time, the value of newly signed design contracts fell further after coming close to growth the previous month.

Business conditions remained soft at architecture firms in all four regions of the country in July. Firms in the Northeast reported the weakest conditions for the second straight month. The three other regions saw the pace of decline ease slightly. Billings fell across every specialization. Firms with multifamily residential and institutional specializations posted slight growth earlier this year but have since seen conditions soften. Firms with a commercial and industrial specialization have not reported a rise in billings since July four years ago.

“Macroeconomic uncertainty continues to weigh on the built environment,” said AIA chief economist Richard Branch. “High oil prices are putting upward pressure on inflation and may lead to even higher rates in the back half of the year. This will put additional pressure on developers and may lead to a further weakening in billings.”

Regional averages were as follows: South (48.7); West (47.8); Midwest (46.7); Northeast (44.8). 

The sector index breakdown was multifamily residential (48.4); institutional (47.4); commercial/industrial (46.7); and mixed practice (43.2).

The project inquiries index was 52.6, and the design contracts index was 47.2.
