Prime Mixed-Use Asset Historic District Main Street Frontage Turnkey + Income Producing 331 Main Street offers an exceptional mixed-use opportunity in the heart of Old Town Longmont's Historic District. Originally home to Longmont's first J.C. Penney's Business and now recognized on the National Historic Register, this 6,322 sq ft landmark blends historic significance with modern functionality, strong visibility, and consistent income. The main level features a leased retail storefront along Main Street and a full commercial kitchen in the rear-ideal for hospitality, specialty retail, production, or service-based concepts. The upper level includes two residential units-a studio apartment and a two-bedroom apartment with a private rooftop deck offering sweeping views of downtown and the surrounding district. With updated systems, roof improvements, and interior enhancements, the property supports long-term stability, reduced operating costs, and reliable tenant retention. Modified Gross leases (utilities + taxes included) further streamline operations for both tenants and ownership. In 1898, a young James Cash Penney opened his first shop here at 331 Main Street, a meat market and bakery that became the foundation of what would grow into the national JCPenney department store chain. Over the next century, this historic Main Street building housed long-standing retailers like Woelz Brothers Clothing and now stands as a contributing building in the Downtown Longmont National Historic District. Showings must be at least a 24 hour notice. Showings begin Friday November 21st.
