Leaders in Jeannette have ordered 12 properties to be demolished after the city determined them to be a threat to public safety.
The 12 homes on the list plus eight already approved for demolition are all located in the southern part of Jeannette.
Officials say some of the homes have become trash dumps and many are used as drug dens.
Fire Chief Bill Frye says the homes on the demo list are just the first that have a date with destruction.
He said the goal is to get at least 50 and as many as 100. For a home to qualify for demolition, the property must be south of the train tracks that run through the center of town.
Jeannette is using community development block grants to pay for the demolitions, which has $10.4 million set aside.
The owners of each property will have 10 days to appeal.
