We had a situation where owners were responsible for regular maintenance issues where they needed to obtain a report and send the report back to the SM. Each year they were reminded to get this done. And each year the SM had to send out another, and another, and another reminder.
SM told the OC they were not happy sending out these reminders, to the same owners, over and over, year after year. So they told all owners that they will send out a reminder and if they did not comply with the maintenance checks, they would be charged $50 for a further reminder.
We have also had instances of group inspections where the owners were told that should they not allow the inspection to be carried out on that day, then they would be charged for the full cost of a follow up inspection.
This seems to have worked. People only need to be charged extra once to be more responsive in the future.
When it hits them in the hip pocket, they will usually respond/comply!
