No its not a fine it is an admin charge for the extra work the SM has to do in continually sending out reminder notices. They do the first one for free. And if their is a group inspection organised and an owner does not allow entry, why shouldn't they pay for their own rescheduled inspection. Many tradespeople do charge for “inspections”.
We had one owner who, after complaining about an issue (waiting until the AGM to complain) the EC organised someone to come out, do an inspection and a report. The owner declined to open the door on the arranged day saying “I'm too tired today!”. They should pay for an additional inspection themselves! If adequate time is given for inspections and the owner has not indicated that this day is not suitable, then why should other owners have to “pay” for another inspection, and another in some cases.
I do believe that adequate notice needs to be given for inspections. Many residents do not like leaving keys with someone and may not have a close family member or friend to come over, especially at late notice. So I think that two dates should be given (perhaps one weekday and one weekend?), therefore two inspections arranged and at least a couple of weeks notice. Sometimes it is just a matter of giving people enough time and options to arrange their lives to be there.
