Update: By June of 2018, the site of the buildings was still a weed-choked lot.
A demolition permit was issued for $10,000 in late October to wreck the old Second Empire townhouse that once stood connected to Jamison Memorial Church. A friend tipped me off to the recent events.
The later wing built to the house in the back, attaching it to the church, is also being demolished. The church is safe.
