In July, a judge ordered that Saint Nicholas Parish could raze the 110-year-old church, which the city considers historic. Now, the city has withdrawn its appeal of that decision, meaning the demolition can go forward.
Last fall, the city's Historic Review Commission had denied a certificate needed for the demolition.
The Diocese of Pittsburgh and the parish, which now meets in another building, say the old church closed in 2004 and costs too much to maintain. But the city's Historic Review Commission wanted the building preserved because it's believed to be the first Croatian Catholic church in the United States.
Church officials say the building is unstable and unsafe.
