This is one of the stupidest rules I’ve seen (in NSW Strata act) and can you blame people for ignoring it when renovating a kitchen will cost them an extra $2,000 to absolutely no advantage.
I don’t see WHY you need a bylaw to do any internal renovations that doesn’t affect the structure or outward appearance of the property. What you do within your own home is yours business (so long as it doesn’t affect other residents adversely). I’d ignore this rule the same as your neighbors have done.
How many people would pay an extra $2,000 to have an a/c fixed to an external wall that might not be visible to anyone except that lots resident.
QLD just requires a simple majority vote authorizing these type of alterations and then only if it’s visible form outside the lot or structural.
