There are more than 4,600 abandoned homes spread across Atlantic County, with the bulk in Egg Harbor Township, Galloway Township and Atlantic City. Municipalities in the county have been collecting data on empty and foreclosed homes to try and force those responsible for the properties – the banks, or mortgagees – to take responsibility for their upkeep, in an effort to prevent neighborhood blight. We compiled an interactive map of the properties, using data obtained via an open records request from the Atlantic County Improvement Authority (ACIA). The data, obtained earlier this month, is not perfect. Some street addresses listed in the database could not be identified. And some of these properties may have already been sold.
