334 N Main Street

About this home

334 N Main Street presents a rare opportunity to acquire a historic, income-producing mixed-use building in the heart of downtown St. Charles. Originally constructed in 1835, this brick building totals approximately 5,712 square feet across two floors plus a full lower level of approximately 2,850 square feet, situated on a 0.093-acre parcel with direct N Main Street frontage. The upper floor is fully utilized as Airbnb and shorter-term apartment units, generating a true net operating income of approximately $42,000. The first floor offers approximately 2,862 square feet of turn-key gym space – a dramatic 90-foot-deep open floor plate with two private offices and a restroom – supported by locker rooms and showers in the lower level. This space is being marketed for lease at $25.00 per square foot NNN; a signed gym tenant would add roughly $70,000 of annual income, more than doubling NOI and giving an investor immediate, executable upside on day one. At the $950,000 asking price, that translates to approximately $166 per square foot – well below replacement cost for historic Main Street product. Zoned General Commercial (AB2), the property supports a broad range of retail, service, fitness, hospitality, and residential uses. The location benefits from 77,283 vehicles per day along the adjacent Riverside Drive corridor and a Walk Score of 79, reflecting the district’s exceptional 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. With stabilized short-term rental income upstairs, a turn-key gym opportunity below, and irreplaceable Main Street real estate, 334 N Main is a compelling acquisition for investors seeking both current cash flow and meaningful near-term growth.
