This map comes from reporting by Sarah Rahal about the abundance of signs placed by local and regional businesses all across the city. The City of Detroit seems to be implementing its “sign ordinance” against unapproved commercial signage along with enforcement.

In total, 16,000 signs have been removed in 18 months. The city’s Blight and Remediation Team has removed 615 signs from Shaw’s Plumbing business since February 2022.
