As I understand it, the appointment of a compulsory strata manager is at the petition of an owner. Remember there are no such thing as strata cops.
The petitioning owner nominates the strata manager to be appointed. The other owners will usually oppose the appointment of a compulsory strata manager, and would not come prepared with an alternate.
So the disaffected owner gets to choose the compulsory strata manager. If it was me, I’d make sure thst manager was responsible.
Having said thst, I spoke to a strata manager about compulsory appointment. He said thst firstly, their fees for such an appointment were several times the normal fee due to the amount of work and responsibilities.
Secondly, he says that they do things “ by the book”. That means that any maintenance is done.
Anecdotally I have heard that since the strata manager is now god, he looks to get the maintenance jobs done, but not necessarily at the lowest cost ie the work goes to their roster of tradies.
I don’t believe that a compulsory strata manager would line their pockets, but since there is no committee to question them, the owners don’t get the cheapest prices.
