Donald Trump’s business has breached New York City law because it failed to register Trump Tower with the city’s department of housing.

The Trump Organisation, which has a $100 million (£80.1 million) mortgage on Trump Tower, failed to renew its annual registration with the New York City Department of Housing Preservation and Development after it expired in September 2016.

Failing to renew the registration of properties with the housing authorities can result in a fine of up to $500 (£400), and revokes some of the rights enjoyed by property owners.

A spokesperson from the Department of Housing Preservation and Development told The Independent that the property registration had expired in September 2016, and that an ‘I-class’ violation was issued in October 2016.

They added that following reports about the violation of law in the media, Trump Tower had been registered with the department on Tuesday, but that they were still waiting for signed documentation to remove the violation on record.

A spokesperson for the Trump Organisation meanwhile told The Independent in response to the reports: “This was an inadvertent clerical error that has since been remedied.”

The managing agent on the expired registration for Trump Tower, where the First Lady and the couple’s son Barron are still living despite Mr Trump having moved into the White House, is reportedly listed as the Trump Corporation.

It comes as figures showed the security costs required for Melania Trump and their son to remain living in Trump Tower instead of moving into the White House, as is generally the protocol for the families of US presidents, could cover recently announced cuts to two major education programmes.

Security expenditure for Ms Trump and 10-year-old Barron costs between $127,000 (£102,000) and $145,000 (£116,000) per day, or an average of $136,000 (£109,000), according to the New York Police Department (NYPD).
