Carrion admited in an email to the newspaper that he hasn't paid a bill from the architect who designed a porch and balcony for his City Island home, the New York Daily News reported.
Carrion was recently appointed as Pres. Barack Obama's White House Office on Urban Policy director.
Carrion explained he believed the bill wouldn't be paid until a final survey is filed and approved, which should happen soon.
The architect, Hugo Subotovsky, was described as a key player in a Bronx development project that once needed Carrion's approval.
The bill from Subotovsky is reportedly for a total of $3,627.50, for work performed two years ago.
