Almost never. This is one of the most important metrics for evaluating service quality and one of the least frequently disclosed in developer marketing materials. Buyers should ask specifically for the building's operational staffing plan — total headcount by department, shift schedule, and resulting ratio per unit. A building with a genuine service commitment will have this documented.
Developer marketing materials will not volunteer this number. Buyers have to ask for it — and how the sales team responds is itself a diagnostic.
New development. Ask for the operational staffing plan: total headcount by department, shift schedule, resulting ratio per unit. Buildings that cannot produce it are signaling that staffing has not been planned with the specificity real service delivery requires.
Completed buildings. Review the annual HOA budget personnel line items. Staff costs are typically 40–60% of the operating budget in a well-run luxury building; dividing by roughly $60–80K all-in per staff member gives a rough headcount.
Talk to residents. Current owners are the most reliable ground truth on actual service quality — management cannot control what they say to prospective buyers.
