FDH said: “The chair should say no, followed immediately by ‘that is not in the jurisdiction of the committee’. “
I fear that may be a very narrow interpretation of strata law. The Chair can’t say yes or no, but they should suggest putting it up for consideration at the next committee meeting, at which the committee can decide whether or not to recommend it to the owners corp at a general meeting.
In fact, if the door is in a state of disrepair, the committee can just agree to fix or replace it. But either way, the chair should be less dictatorial and more helpful.
