615 Griswold St Detroit, MI 48226

A recently renovated 18-story historic office asset in an iconic downtown landmark building. The property features an efficient horseshoe floor plate designed for strong natural light and flexible layouts, with mechanical systems on each floor to support a range of tenant buildouts or conversion scenarios. Common areas and the lobby have been modernized, including elevators and shared spaces with updated finishes and systems. On-site valet parking is available, with additional nearby structured parking options noted. Approximately 14% of the building is currently occupied, creating a meaningful lease-up and repositioning opportunity. The first-floor includes retail availability in two spaces ranging from about 2,500 to 8,600 SF, and Jimmy John’s is located on the first floor with a lease in place through 2030.

Positioned in the core of Downtown Detroit, the building’s first-floor retail presence provides immediate street-level utility while the upper floors offer adaptable office configurations. The asset is described as positioned for repositioning or adaptive reuse, with potential noted for multifamily, hotel, or mixed-use transitions.

This property may appeal to investors seeking a value-add office strategy focused on leasing momentum and operational modernization, particularly given the flexible floor plate and per-floor mechanical support. It can also fit tenants who benefit from efficient, naturally lit office layouts, and retailers seeking first-floor space supported by an in-place national quick-service tenant through the end of the lease term.
