Turn-Key Gym Space - Historic Main Street · Retail Property For Lease · 2,862 SF

Positioned in the heart of historic downtown St. Charles, 334 N Main Street offers a rare turn-key fitness opportunity on one of Missouri’s most walkable and heavily trafficked main streets. The first floor delivers approximately 2,862 square feet of open, equipment-ready gym space featuring a dramatic 90-foot-deep main floor, two private offices ideal for staff, personal training, or consultations, and a dedicated restroom. The lower level adds approximately 2,850 square feet complete with locker rooms and showers – an amenity nearly impossible to find in the Main Street district and one that allows a fitness operator to open with minimal capital investment. The space is offered at $25.00 per square foot NNN. The building itself is a classic brick storefront originally constructed in 1835, blending historic character with functional modern improvements. Zoned General Commercial (AB2), the property supports a wide range of fitness, wellness, studio, and service uses. Frontage directly on N Main Street places a tenant in front of 77,283 vehicles per day along the adjacent Riverside Drive corridor, while a Walk Score of 79 reflects the district’s strong year-round pedestrian activity. Downtown St. Charles draws millions of visitors annually with its brick-paved streets, riverfront festivals – including the nationally recognized Christmas Traditions celebration – and its position along the Missouri River and Katy Trail. Neighbors include Mov on Main, Climb So iLL at the Steel Shop, and the district’s dense collection of boutiques, restaurants, wineries, and entertainment venues, with SSM Health St. Joseph Hospital anchoring the corridor to the south. The surrounding residential and daytime population provides a built-in membership base for a boutique gym, cycling or yoga studio, CrossFit affiliate, physical therapy practice, or broader wellness concept. With a turn-key build-out, lower-level locker rooms and showers, and unbeatable Main Street visibility, this is a true plug-and-play opportunity for an operator seeking immediate presence in one of the St. Louis region’s most iconic retail districts.
