Visitors gather at the grand opening of the Park51 community center and mosque on Sept. 21.
The developer of an Islamic cultural center near the World Trade Center site and the owner of the building it's planning to buy are in a dispute over rent.
Consolidated Edison owns part of a site that the Park51 developers want to use for the center. The utility says that after an appraisal, the rent for that part has gone up, and now Park51 owes $1.7 million in back rent.
Park51 did not respond to an email seeking comment, but disputed the figure in court papers. The developer says Con Ed is using an incorrect formula to determine the rent and any monies owed in back payments.
A court date in connection with the dispute is scheduled for November.
