A section of floor in the bathroom of a first-floor apartment in Highbridge collapsed into the cellar below Sunday morning, injuring a tenant, according to the Department of Buildings.

The incident occurred around 10 a.m. at 1204 Shakespeare Ave.

The FDNY said one person was transported to New York Health + Hospitals/Lincoln.

The DOB said that person had minor injuries.

An initial DOB probe determined that “a lack of proper maintenance was a contributing factor to the collapse.” It issued a violation to the landlord.

The DOB said in an incident update, “We have also ordered the landlord to immediately contract the services of a professional engineer and submit to DOB an engineering report on the structural stability of the floor inside the rest of the apartment.”

Tenants told News 12 that lack of maintenance has been an ongoing issue from leaks to crumbling walls, and they said it's leaving them feeling ignored.

A partial vacate order was issued to the affected apartment and to the cellar area.

The building's landlord has also been summoned to attend a hearing set in October over the violations and they are now required to submit a report to the DOB about the floor stability.
