Why St. Charles

Established industrial in one of the region's fastest-growing counties.

St. Charles sits just across the Missouri River from St. Louis County, between I-70 and Route 370. It gives you a St. Charles County address, a growing workforce nearby and a quick run to the airport.

What the buildings look like

The anchor is Fountain Lakes Commerce Center, a 500-acre business park on Route 370 with buildings from about 25,000 to 290,000 SF. Its tenants include Almo Distributing, MiTek, Southern Glazer's, Vi-Jon and Victory Packaging. Just west, Premier 370 Business Park in St. Peters adds big-box distribution for companies like Amazon, FedEx Ground and Medline.

St. Charles also has older industrial areas off I-70 and Highway 94, including the Little Hills Industrial and Friedens Road areas. That's where smaller shop, flex and warehouse space for contractors and growing local companies tends to be.

What to know before you search

Compare both sides of the river. Taxes, incentives, labor and drive times differ between St. Charles County and St. Louis County. If your customers or employees are on both sides, I'll lay out the true occupancy cost of each option.

Small spaces are tight. Demand from contractors and service businesses keeps small bays scarce. Across the metro, CBRE reported an average industrial asking rent of $5.60/SF and vacancy of 6.9% in Q3 2026. I'll get you current St. Charles numbers for spaces that actually fit.

Your Broker

Work with someone who's owned industrial property.

I'm Brian Travers, Managing Principal of Optimus, part of KW Commercial. I've spent more than 30 years building, acquiring and running companies and commercial real estate portfolios in St. Louis, so I look at a space the way an owner and operator does: loading, power, access, operating costs and room to grow, not just the asking rent.

Industrial along the I-70 corridor, from North St. Louis out to Warrenton, is my focus. St. Charles is right in the middle of it.
