The FDNY and inspectors from the Department of Buildings responded to 500 West 174th Street in Washington Heights.
Firefighters said there were concerns that one interior wall inside the building might be unstable after several large cracks were discovered.
There are 27 apartments in the building, and a temporary vacate order was issued for 12 of them so engineers could get inside and inspect those units.
Everyone was back in their apartments by mid afternoon, with the exception of the one apartment where the cracks were found.
No injuries have been reported.
