Clark Properties Saint Louis Portfolio Marcus & Millichap is pleased to present the opportunity to acquire the Union Seventy Center Business Park located at 3901 Union Boulevard in Saint Louis, Missouri. The subject property consists of 1,640,597 square feet of rentable industrial space (2,204,279 square feet in total) and is situated on a combined 92.68 acres of land. Anchored by Triad Manufacturing, Clark Logistic Services, and Iron Mountain, the multi-tenant asset features 25 suites, 132 dock-high doors, 26 grade-level doors, and an unused rail spur operated by the Terminal Railroad Association of St. Louis. The property includes 8 paved lots, approximating 20 acres of parking lot/outside storage. Primely situated only 0.6 of a mile from Interstate 70, the property has easy access to the Saint Louis Lambert International Airport. With the property containing heavy tenant improvements that allow for specialized manufacturing and shipping activities, the anchoring tenants are relatively less sensitive to rent increases. Given the inflationary environment, rising industrial vacancy rates, and slowing rent growth, owning specialized assets that give landlords more pricing power over rents is growing in importance.
In addition to the benefits of owning a specialized asset in today’s economy, this sale offers national investors the opportunity to claim a stake in a market whose fundamentals outperform most of the top markets across the nation. At 5.2 percent, the industrial vacancy rate in Saint Louis sat 250 basis points lower than the 7.7 percent national average in 2025. Unlike most U.S. markets, annual rent growth in Saint Louis experienced a rebound in 2025, rising by 180 basis points to 4.7 percent, nearly tripling the national average that slipped to 1.7 percent. At the close of 2025, there were 4.3 million square feet of industrial space under construction in Saint Louis, representing just 1.3 percent of the existing inventory. The construction of Boeing’s 1.1 million-square-foot manufacturing facility exemplifies the industrial benefits that Saint Louis maintains (CoStar, classes A, B, & C, minimum 10,000 square feet, national average based on top 50 metros).
The Saint Louis metro is near the geographic center of the United States, within 500 miles of one-third of
the U.S. population. About 2.8 million people call the metro area home, with Saint Louis hosting over 319,000 residents. Located at the confluence of the Mississippi and Missouri rivers, the metro area encompasses counties in both Missouri and Illinois. The economy of Saint Louis is anchored by the logistics industry, with trade, transportation, and utilities accounting for the largest share of employment. In addition to the Gateway Arch, which continues to serve as a major tourist attraction, Saint Louis is also highlighted by one of the nation’s most prominent urban parks. Covering 1,326 acres, encompassing the Saint Louis Zoo, Art Museum, History Museum, and Science Center, Forest Park measures larger than New York’s famed Central Park. Saint Louis is also the host of two major professional sports teams, the Saint Louis Cardinals of Major League Baseball and the Saint Louis Blues of the National Hockey League (Marcus & Millichap, Wikipedia).
