The strata ACT says, in section 106, that the owners corp is responsible for “common property and any personal property vested in the owners corporation.”
I have to admit that I have never understood what “personal property vested in the owners corporation” i. But I would look at it this way, just for the sake of finding where to draw a line, anything that would be covered by strata insurance should be the responsibility of the OC. Anything that isn’t should be the responsibility of the lot owner.
Make no mistake, this is totally arbitrary and subject to potential challenge.
But the fact that everybody in the block is affected means that the cost is spread to some extent. OK, the person with the heavy drapes and fancy blinds will have to pay more. But would they save money if they had to pay a share of the cost of everyone trying to prove that they were paying an unfair share?
Everybody needs to get a grip and be glad the OC is doing something for the building.
