Milwaukee’s Vacant Building Code

On January 1, 2010, the City’s new Vacant Building Registration (VBR) ordinance Chapter 200-33-64 of the Milwaukee Code of Ordinances (MCO) took effect. The new VBR ordinance requires owner(s) of residential and commercial property left vacant for 30 days or more to register the property with the Department of Neighborhood Services (DNS) and take steps toward assuring the property is secure, properly maintained and not creating a hazard for the surrounding community.
