This brief provides a practical guide to local “lead laws” for cities interested in preventing exposure to lead-based paint hazards. It begins with a primer on these ordinances: what they are and how they work. We then provide a brief scan of local lead laws around the country. The third section draws on interviews with practitioners working to implement three recently approved lead laws in Cleveland, OH; Syracuse, NY; and Toledo, OH; to identify key decision points. Finally, we provide individual case summaries on the three sites.
