They pose a threat to public safety, meeting the definition of a public nuisance

Beyond houses, there are a variety of property types that become abandoned and meet the conditions identified above. Each property type raises unique challenges for policy makers, urban planners, and tax payers.

Property becomes abandoned for a variety of reasons - most often due to achange in the economy that lead to a lack of funds to maintain it. The underlying reasons also don't tend to just impact a single home owner but entire neighborhoods and cities. Abandoned properties pose a serious problem for communities.
A gradualreduction in city population can cause higher vacancy rate of homes and other property types within that city. The cities on the right are the ones that have lost at least 20% of their population since 1950. Detroit presents a glaring example - its population has declined by 62% since 1950 after the city's lifeblood, the automobile industry, could not profitably compete globally anymore.
Economic crises can cripple cities affecting large scaleforeclosures and declines in property values,making them less attractive to buyers. Detroit shows a glaring example of this phenomenon during the economic resession of 2008, when tax foreclosures increased significantly and home values dropped in addition to continuous flight of people.
In addition to the underlying disease of abandoned properties, there are multiple characteristics about a city that have correlation with property vacancy rate. The graph below represents this relationship for 20 cities in the United States - 10 cities with the highest vacancy rates in red and 10 cities with the lowest vacancy rates in green. Click on the buttons below to look at this relationship.
Many major cities in the United States have experienced increase in vacancy rates and they continue to struggle to deviseeffective programs and policies to mitigate the dangers of abandoned properties. Among these cities, Chicago has gone through a series of transformations in trying to form responses to these properties since the late 1940 to even now.
Chicago is the 3rd biggest city in the US by population, after New York City and Los Angeles.
In recent years, there has been an increase in different type of criminal activities in Chicago such as homicides, shootings, and robberies.
From 2010 to 2015, Chicago's population grew by 1%.
As depicted above, Chicago has implemented multiple efforts to fight the problems associated with abandoned properties. Yet, these problems still persist,most notably crime. In 2008, the Chicago expanded their 311 city services line for residents to call and report about abandoned properties in their neighborhoods. Information collected from these calls have been aggregated into a dataset and the city has made it available for the public. As a result, Chicago residents can become more aware of their locations and projects can begin to focus on certain neighborhoods/areas.
To provide a tool to better visualize locations and snippet of the property's data, this map showsall 311 calls for abandoned homes that the city of Chicago received in 2016 and 2017. To explore the map, provide a location or double-click the map to zoom in.

In order to prevent undesirable outcomes, residents should be proactive and look for ways to help the neighborhood's well-being. Here are some actions community members can take when there is an abandoned property in the neighborhood:
Report abandoned homes so that city officials can inspect them.
Collaborate with your community to find new solutions to this old problem.
Often, the owners are banks. Ask them to take care of the property.
Do not enter abandoned homes and inform others of the risks.
