The Department of Buildings says the former Lower East Side synagogue that had to be evacuated Monday night will remain vacant for now.
The building dates back to the 1840s and is now used as an event space.
The DOB says there are vertical cracks in the building's first- and second-floor joists, which support the floors and ceilings.
The department says the property owner must get permits and make repairs before anyone will be allowed back in.
Firefighters responded to reports of smoke at the building on Norfolk Street Monday when they were told by party-goers that the balcony was shaking.
More than 500 people were forced to leave the building in the middle of an event.
No one was hurt.
