There's no simple answer to this question as it depends on shared facilities etc.
Best you can do is scrutinise the budget and make sure the money is being properly spent and not fictious charges back to developer or his cousins etc
At next AGM (or before) make sure you change President and Administrator as both will be family or very cosy relationship!
Of course neither President or Adminsitrator are going to do anything against developer which is why they have to go!!
Do you know if the developer is paying community fees on unsold units - the norm here is to stop if there is no hope of selling.
You probably need to talk to a lawyer to see where fault lies and how claims can be made etc. You have some element of insurance but failing that you can claim from any party developer, builder or architect etc
But of course the existing powers are not going to be going out of their way to facilitate or advise on claims.
Also as far as I'm aware the developer only has one vote even if he is up to date on his community fees and it's not one vote per property - I think there was a case on this before?
