This two-story mixed-use building has an updated interior and a multi-tenant configuration designed for separate operations. The front portion includes retail and a medical suite on the ground floor, along with two separated office areas on the upper floor. Shared amenities serve the upper offices, including a large conference room set up for virtual meetings, a kitchenette, and two bathrooms. The medical suite is self-contained with its own entrances, HVAC, security systems, and bathrooms for added security. The back portion is a two-story, clear-span warehouse with two drive-in doors, a loading dock, and a small office, and it is currently leased. A basement storage area with its own entrance and a drive-in door is also leased to a separate tenant.

The property sits on about one acre and is zoned B-3 Highway Business. It is located at a signalized corner and includes 45 lined parking spaces to support customer and employee access.
