If you feel the fee is too high then you should go to the Board meetings to see if the fee can be changed.
Everything depends upon what your offering plan and proprietary lease say. In general, the board can institute fees at their discretion and the only way to change that is for the board to rescind the decision.
I hope this helps. Feel free to contact me if you have any more questions or as Anna suggested, please contact a real estate attorney for a more building specific response.
