A group of Parkchester condominium tenants rallied Wednesday in protest of a 16 percent increase in maintenance costs.

The protesters say they've had no hint of a compromise from their board of managers, so they rallied outside the board's office.

The increase costs residents about $600 each, they say.

State Assemblyman Luis Sepulveda and state Sen. Ruben Diaz joined the rally.

Sepulveda, who described the board members as "cowards" who refused to negotiate, called on the board to explain why it increased the maintenance bill. The ongoing issue is beginning to attract attention from Mayor Bill de Blasio and the attorney general, who say they may take the board to court.

The board president told News 12 last month that the increase was necessary.
