NYC’s Buildings Department ordered three more parking structures to be partially or completely vacated due to severe structural issues Wednesday following last month’s fatal collapse of a garage in Lower Manhattan.

Seven parking structures have now been partially or completely closed since the April 18 collapse, which killed the garage’s manager, Willis Moore, and injured five others.

Two of the garages are located on the East Side of Manhattan, while the third is in Brooklyn.

Inspectors ordered the complete clearance of the five-story parking garage at 228 East 9th St. after discovering it “in a state of disrepair” so bad there were cracks in support beams and the elevator shaft. Investigators also noted exposed steel reinforcements in the building.

The Buildings Department not only discovered structural issues with the concrete slabs and brick columns in a garage attached to an 11-story residential building at 148 Madison St. on the Lower East Side — the city review found that operators had crammed in twice as many cars as allowed, fitting 71 when only 32 are permitted.

Authorities ordered the Madison Avenue structure to be partially cleared.

In Bedford-Stuyvesant, at 1368 Fulton Street, officials found the garage for a six-story office building also suffered from poor upkeep, discovering spalling concrete in the ceiling of the facility, missing masonry and leaking plumbing throughout. That garage was ordered partially cleared as well.

A DOB spokesman said the problems were identified as part of the inspection blitz launched following the collapse of the Ann Street garage.

All told, city inspectors and engineers have checked 78 parking garages across the five boroughs that had outstanding serious violations of the Big Apple’s safety codes in the aftermath of the collapse, officials say.

Documents obtained by The Post showed the Ann Street garage had a long history of significant structural issues, including cracks in the connection joint between one support column and a ceiling beam. Cracks up to 11 feet long had also appeared in several of the walls and substantial upgrades were needed to comply with the city’s fire code.
