About This Property

This rare 24,750 SF flex/retail asset presents a unique opportunity to own a high-quality, well-maintained property in the heart of Midtown Fort Collins. Situated on 1.37 acres just off South College Avenue, this property offers exceptional access, visibility, and long-term upside in one of Northern Colorado's most sought-after markets. The property is comprised of seven individual tenants, each separately metered, allowing for future condo conversion potential. Featuring ten 12-foot roll-up garage doors, 14 bathrooms, and 66 reserved parking stalls, the site is thoughtfully configured to accommodate a wide range of tenants.

Recent capital improvements include HVAC and roof upgrades (2020), parking lot resurface (2026) and exterior repaint in 2024. With strong fundamentals, low-maintenance profile, and built-in future flexibility, 3501-3509 Mason Street offers a great opportunity in a premier Fort Collins location.
