Elected officials are calling for an investigation into a move by the de Blasio administration that removed a protection on a Lower East Side nursing home — allowing its operator to flip the site for luxury condos at a $72 million profit.

The Allure Group bought the building at 45 Rivington Street in February 2015 for $28 million, and said it would keep it as a nursing facility if a restriction that it be run as a health-care non-profit were removed, according to city officials.

In June, the restriction was lifted, and in November, the city got $16.1 million based on appraisals.

Last month, Allure sold the site for $116 million, the Wall Street Journal reports.

“It’s really outrageous,” said Manhattan Borough President Gale Brewer, who called for an investigation.

Officials said they are conducting an internal review.
