Southern California's commercial real estate market posted a puzzling Q1 2026: vacancy rates rose year-over-year across most sectors while net absorption turned positive, according to a May 18, 2026 report from VOIT Real Estate Services analyzed by firsttuesday Journal. The contradiction stems from new construction hitting the market faster than businesses can fill it, even as major warehouse tenants like Amazon boost occupancy numbers. The report warns that business closures, layoffs and growing fuel prices have left business owners and consumers cautious amid what it calls an undeclared real estate recession.

The data reveals sharp regional differences across San Diego, Orange County, Los Angeles and the Inland Empire. San Diego's industrial vacancy hit 7.29% in Q1 2026, up from 6.69% a year earlier—the highest since Q1 2014—while office vacancies reached 13.61%, up from 12.98% in Q1 2025. Downtown San Diego office vacancy sits at 34%. Retail vacancies climbed to 4.65% from 4.19% year-over-year. Orange County's industrial vacancy rose to 5.79% from 5.31%, now at its highest point in years, though office vacancies improved to 13.52% from 15.48% a year ago—still well above the 11.80% recorded in Q4 2019. Los Angeles industrial vacancy held nearly flat at 5.53%, up barely from 5.51% in Q1 2025 but far above the 2.20% pre-pandemic standard. The Inland Empire saw industrial vacancy jump to 8.82% from 7.57% year-over-year after bottoming at 1% in 2022.

Despite climbing vacancies, net absorption—the change in occupied space—flipped positive across the board. San Diego industrial posted +863,148 square feet in Q1 2026, up from -239,091 square feet in Q1 2025, ending three consecutive years of negative absorption. The report notes this gain hinged entirely on one Amazon warehouse completion. Orange County industrial recorded +531,781 square feet, reversing from -272,207 square feet a year prior, marking two straight positive quarters. Los Angeles logged +540,615 square feet, down from +664,113 square feet in Q1 2025, while the Inland Empire recorded +1,587,049 square feet, down from +2,782,602 square feet the prior year. San Diego retail was the outlier, posting -187,877 square feet compared to -331,938 square feet in Q1 2025.

The report explains the vacancy-absorption paradox simply: new projects were opened to the market but are not yet occupied. Big warehouse operators like Amazon are increasing net absorption rates for the moment, overshadowing additional availability due to closures of small businesses. In Los Angeles, the report attributes the turnaround to tariff avoidance by distributors and online commerce growth, noting 1.1 million square feet of positive net absorption in 2025 followed 9.4 million square feet of negative absorption in 2024. For the Inland Empire, total net absorption from 2022 through 2025 reached just 13 million square feet—one-fifth of the 65 million square feet absorbed from 2018 through 2021. The office sector faces a different threat: the report warns that efficiency of workflow by all businesses integrating AI technologies as an assistant is certain to significantly disrupt this sector, calling AI "an office assistant that requires no space" likely to reduce employment.

The outlook depends on forces beyond landlords' control. The report predicts that so long as global turmoil keeps interfering with supply chains, expect the upward trend to continue for industrial vacancies. It points to an economy-wide recession—not just a real estate recession—on the horizon, with the culprit being the consequences of the tariff and military wars underway and the shrinking of the labor force. For struggling retail, the report bluntly states that thousands of stores across the U.S. are projected to close this year, facing "seemingly irreversible headwinds from consumer shopping online." The bottom line: a few major tenants are masking the slow shutdown of smaller businesses, and that imbalance can't hold forever.
