OK, a couplre of points – the strata manager is not the final arbiter of howthis should be done … it’s the owners corporation that has the final say and once your fellow owners realise they are each going to be slugged $1500 every time they want to undertake a minor renovation, they may be more sympathetic.
The fact that your strata manager says they have prior experience of this suggests that they may have an existing by-law on their records that could be used for your purposes.
But individual by-laws for each item of work done in private lots is the least efficient way of doing this.
What you really want is a by-law that says all owners will take responsibility for all common property affected by renovations in their lot whether they get permission for it or not.
You want another by-law that outlines conditions for renovations – hours of work, noise limits etc etc – which also apply to all renovations.
Even if the Strata Manager can persuade the majority of owners that they need a lawyer-written by-law, it will save everybody money if you get one that applies to every future renovation. And, because the by-law is to everyone’s potential benefit, the owners Corp should pay for it.
