In the scheme but not really in the building
A ground-floor commercial lot with its own street access uses very little of what the scheme provides. Its customers do not use the residential lobby, its staff do not use the lift, and its waste may go out through a separate arrangement entirely. It nonetheless contributes to common property costs according to unit entitlement like every other lot. Very little of what the scheme provides is of any use to them.
That is the structure and it is not going to change, but it shapes how the commercial owner engages with the scheme. They tend to be the least involved member of the owners corporation and the most likely to query the budget, because the relationship between what they pay and what they use is the least visible in the building. A clear breakdown addresses more of that than any amount of explanation.
