Developers at 2625 Bedford Ave. had active permits for excavation and foundation work tied to plans for a new three-story building at the site.
In March, the Department of Buildings issued a stop-work order after inspectors found that the developers had demolished the existing structure without adequate protection for neighboring properties, including 1321 Flatbush Ave.

A little more than a month later, investigators found that demolition had continued despite the order, leading to a $10,000 fine. The stop-work order was lifted in May after officials determined the developers were in compliance.
