City council speaker blasts mayor’s office for impeding nursing home probe

City Council Speaker Melissa Mark-Viverito, a close ally of Mayor Bill de Blasio, said Wednesday it’s “very troubling” that the mayor’s office impeded a city investigation of a botched Lower East Side real estate deal.

The city Department of Investigation issued a scathing report last week on the administration’s handling of the deal — which allowed for the conversion of a formerly protected nursing home into luxury apartments — and highlighted a lack of access to requested documents and computer terminals.

“It’s very clear what the authority of DOI is. The Department of Investigation is to have full access to documents — so that is a concern,” Mark-Viverito said at a press conference calling for similar deals to become part of the more transparent land use review process.

“Clearly access to the documents should not have been made difficult,” she added. “It should have been freely made available, so that aspect of the report is also very troubling.”

The DOI said in one case, Law Department officials, who report to the mayor, redacted 990 pages out of 1,000 that were requested.

City officials also blocked access to all computers in the mayor’s office.

Hizzoner has insisted that “a huge amount of material was provided.”

While he said no one would be fired despite the DOI’s conclusion that top City Hall officials knew or should have known about the faulty deal — and done something to stop it — Council Member Margaret Chin (D-Manhattan) said discipline was called for.

“I’m troubled by what [DOI] found and I believe that those responsible should be held accountable,” she said.

The former nursing home at 45 Rivington St. was purchased by The Allure Group in 2014, and the city nixed restrictions limiting the uses of the property in exchange for $16.1 million in 2015.

Earlier this year, The Allure Group sold the building to a trio of luxury housing developers for $116 million — even though administration officials had been looking to turn it into affordable housing.

The deal is still under investigation by the New York US attorney, the state attorney general and the city comptroller.
