Generally, strata schemes are not considered to be workplaces. ( yes people work from home in the building, and contractors work on the building, but under legislation, that does not class a strata building as a workplace).
I believe that if someone is working on your building that is a workplace. That’s why you have to make sure that any tradie working on your block has their own insurance. And it’s the reason you have to put up warning notices if your block is covered by CCTV.
I may be wrong and you refer to “legislation”. For the sake of clarification, what laws are you referring to?
