Am I Rent Stabilized? is a web application that helps New York City tenants find out if their landlord may be illegally overcharging them for a rent-stabilized apartment and motivates them to take action. The app was developed by Chris Henrick, who used open data as a prompt for civic action rather than solely for visualization and analysis. The app uses a database of properties that are likely to have rent-stabilized apartments and recommends a course of action to users. It also provides information on local tenants' rights organizations operating in the user's neighborhood and allows users to input their address to geocode and find nearby organizations. The data was processed using Python, PostgreSQL, and CartoDB, and includes custom polygon geospatial data representing each organization's service area.
