one can’t help being nervous that some owner does something illegal, that no-one gets to hear about, until something goes wrong and the BC has to solve a problem.
It might be worth putting together a polite and friendly circular to all owners and tenants telling them what they need to do before they can start “renovating”.
This would include reminding renters that they must get permission from their landlords before any work can be done and that the strata committee will inform the owners that work is being done, to make sure permission has been granted.
There are so many people in strata who think that because they own the flat they can do whatever they want, regardless of the effect on common property, but would be happy to know what the rules are.
And it sounds like you need a new strata manager.
