May 2026 brought a fresh round of return-to-office (RTO) pressure – PNC Financial's five-day mandate took effect at the start of the month, while EY told its U.S. tax teams to plan for more in-person time this summer. Both join a growing list of employers tightening face-time policies. At the same time, gas prices climbed to an average of $4.61 in May, making the commute more expensive for employees who drive to work.
How did these competing forces play out on the ground? Did the office recovery continue, or was May the first month this year to show signs of slowing down? We dove into the data to find out.
Fewer Workdays, Slower Upward Trend
At first glance, May's results suggest a slowdown. Total visits to the Placer.ai Nationwide Office Index were 38.6% below May 2019 levels and 1.2% below May 2025.
But the apparent weakness is largely explained by the calendar. May 2026 included only 20 working days, compared to 21 in May 2025 and 22 in May 2019. When adjusting for business days, visits were actually 3.7% higher than last year and just 32.4% below the 2019 baseline – compared to 34.9% for May 2025. In other words, May 2026 was the busiest May for per-working-day office attendance since the pandemic, extending the streak in which every month so far this year has set a post-pandemic high for its respective calendar month.
Still, even when normalized, the pace of YoY growth was modest, suggesting that higher commuting costs may be tempering some of the gains from ongoing return-to-office initiatives.
San Francisco Leads the YoY Pack
The same calendar effect carried across the major markets, where most cities showed year-over-year declines on raw visits that turned positive once working days were accounted for. San Francisco led the year-over-year (YoY) field, with per-working-day visits up 8.2% – tracking the city's AI-driven leasing recovery. With its strongest leasing quarter this year since 2014, declining office availability, and robust net absorption, the city appears increasingly well-positioned to sustain its momentum.
Los Angeles followed at +6.5% YoY per working day, with Dallas, Chicago, Miami, New York, and Boston all in positive territory. Only three markets stayed slightly negative: Denver, down 1.4% from a year ago, Houston, down 0.6%, and Washington, D.C., essentially flat at -0.1%.
Denver's continued softness likely reflects the same dynamics noted last month – a particularly remote-friendly labor market and record-high downtown vacancy. Still, improving net absorption and gradually strengthening demand for Class A office space may portend stronger visitation trends in the months ahead. Houston's slight decline, meanwhile, may partly stem from contraction in its dominant energy sector, where major employers such as Chevron have reduced local headcount.
Miami Still Out Front, Denver Last
On the longer view versus 2019, the RTO rankings held their usual shape. Miami remained the clear leader, sitting 11.0% below its pre-pandemic baseline on a per-working-day basis, with New York next at 18.3% below. Denver finished last once more, down 48.4% from 2019. And San Francisco held onto third-to-last position, showing how far it has come from its former status as the nation's weakest-performing office market.
Still Moving in the Right Direction
The pace of office recovery moderated in May, but the calendar accounted for most of the apparent weakness. On a per-working-day basis, office attendance continued to rise, with gains recorded across most major markets.
Whether lower gas prices or additional RTO mandates will reignite a faster recovery later in the year remains to be seen. For now, however, the data suggests that office utilization continues to inch upward, even as the pace of improvement becomes more gradual.
