Apparently the committee member lives in the building. Visitor parking is by definition not available to this person. You’ll find that the DA or BA under which the local council approved your building requires there to be X visitor parking spaces. You’ll also find that there aren’t any more than X visitor spaces. A committee member can’t change that. The committee can’t change that. The OC can’t change it either, not even to convert it to an EV-charging space.
