Why does this matter?

City Council members and citizens regularly ask for information about blighted properties and nuisances. To do so, they have to contact City staff and even wait on public records requests. Using City of Houston Blighted Properties, we wanted to allow citizens and Council members a more proactive way to see what's going on in their neighborhood.
