This article describes the Vacant Property Registration Ordinance Database, a new database of local vacant property registration ordinances (VPROs) in the United States. Beginning with an industry list, 550 ordinances were acquired, read, and coded on more than 30 characteristics. VPROs grew dramatically in 2008 and 2009, during the climax of the national foreclosure crisis, and the number of ordinances continued to grow after 2009, albeit at a somewhat slower pace. The database provides details on the coverage, requirements, and penalties specified in VPROs across the country.
