The plan does not move when the use does
Unit entitlements are fixed on the strata plan and do not adjust because a lot's business changed. A quiet professional suite replaced by a busy clinic brings several times the foot traffic through the same lobby and lift, and contributes exactly what it did before. Over a year that shows in the condition of the shared areas and in nothing else that anyone measures. Nothing in the scheme's own paperwork registers the change at all.
Whether the scheme can do anything about the contribution is a question for the owners corporation and its strata managing agent, and the answer depends on the scheme's own records and by-laws. What is squarely within the committee's control is the cleaning arrangement, which can be adjusted to match what the building now carries once somebody puts the change on the agenda. A change of use is a legitimate agenda item and it costs nothing to raise.
