What Guardian Building does
The Guardian Building is a 40-story, 486-foot Art Deco Class-A office tower located at 500 Griswold Street in Downtown Detroit's Financial District, built in 1929 and designated a National Historic Landmark by the U.S. National Park Service — the highest federal preservation honor. The asset is owned by Wayne County, Michigan, which also occupies it as its county government headquarters, and features distinctive architectural elements including nearly 2 million custom 'Guardian Bricks,' a five-story Michigan mural by Ezra Winter, Pewabic Pottery tiles, and a Tiffany Clock on the Promenade. The building generates revenue across five streams: full-floor Class-A office leasing (1,000–16,000 sq ft), retail/dining space leasing on the lower level (3,937 RSF currently available), event venue rentals on the Promenade and the 32nd Floor Guardian Club, daily meeting room rentals, and tiered photography access (free public hours plus $150/half-hour private after-hours sessions). Ancillary revenue comes from structured parking at nearby garages. Distribution is conducted through a dedicated in-house leasing team working with external brokers, direct event inquiry via email, and consumer-facing wedding marketplace partnerships with WeddingRule and The Knot. The customer base is bifurcated between a single anchor government tenant (Wayne County) and a long tail of SMB event clients, primarily weddings and corporate gatherings.
