Yes, that’s true … if you are aware of any changes that have been made. The first many ECs are aware of changes is when they have a sticky-beak when a unit is put up for sale. Then it all gets messy if common property has been altered and the unit is sold.
In that case it has been legally established that if the previous owner had changed common property without permission or knowledge of the Owners Corp and the replacement breaks, the Owners Corp is liable to repair the new installation, despite the fact that they didn’t approve it. The example given of changing cheap sliding doors to expensive bi-fold French windows is a real one.
I too believe in the KISS principle but this is strata and nothing is simple. have a look at this posting from about a year ago. As I’ve said elsewhere, there’s logic, there’s common sense … and then there’s strata law which often seems to employ neither.
