Rental property owners, just like other property owners in the city, are responsible for keeping their properties maintained according to the City of Detroit’s property maintenance code. If your property is not properly maintained inside and out, you may be issued a Blight Violation citation, more commonly known as a “Blight Ticket,” by City inspectors, police officers and other City officials with the power to investigate and cite code violations. If you are not registered or do not have a Certificate of Compliance, you are subject to blight tickets.
