The American Institute of Architects’ (AIA) Architecture Billings Index (ABI) recorded its lowest score of 2026 in May, dropping to 44.5. This marks a significant decline from April’s score, which hovered near the 50 mark, the threshold indicating growth in billings. The ABI, a monthly survey tracking business conditions for the architectural industry, has remained below 50 since January 2023, signaling a sustained period of contraction or stagnation.

Economic Headwinds Impact Billings

AIA Chief Economist Richard Branch attributed the notable decrease in billings in May to the ongoing conflict in Iran and rising energy costs. These external factors, coupled with existing economic pressures, have created an environment of uncertainty that is directly affecting architectural firms’ financial performance.

New Design Inquiries and Signed Contracts Also Decline

Adding to the concerns, the May report indicates a dip in new design inquiries, following four months of growth. Furthermore, the value of newly signed design contracts has decreased, reaching its lowest level since January. This dual decline in both future project pipelines and immediate contract signings suggests a broader slowdown in demand for architectural services.

Branch elaborated on the contributing factors, stating, “The uncertainty created by the Iran conflict, and substantially higher energy costs, weighed on architect billings in May. Higher interest rates, rapidly rising material costs, and continued labor shortages all contributed to softer demand.”

Regional and Project Type Variations

While the overall index shows a downturn, billings in the South region were the closest to reporting increased growth, with a score of 49.6 in May. This suggests some regional resilience within the industry.

In terms of project types, firms specializing in multifamily residential projects reported a less pronounced decrease in billings compared to those working in institutional, commercial/industrial, and mixed practice sectors. This indicates that certain segments of the market may be weathering the economic pressures more effectively than others.

Future Outlook for 2026

In addition to the current billing figures, the AIA also surveyed respondent firms about their expectations for billings for the remainder of 2026. At the end of March, 21 percent of firms anticipated a decline of 5 percent or more in their billings for the second quarter. The May survey reveals that now, one quarter of firms expect their billings to decline in the third quarter.

Conversely, 46 percent of firms expect their billings to remain about the same, while 30 percent anticipate an increase of 5 percent or more. This mixed outlook suggests that while many firms are bracing for continued challenges, a significant portion remains cautiously optimistic about potential growth in the latter half of the year.

The report also touches upon broader economic policy discussions, noting that President Trump and Vice President JD Vance contend their “interim deal” with Iran will alleviate some of the financial strain the conflict has caused on the United States and its economy. The impact of such geopolitical and economic policies on the architectural sector remains a key factor to monitor.
