Property managers: that janitorial invoice is a CAM document. 🧾
And "Janitorial Services — $8,400" isn't one.
Here's the split that actually matters 👉
🏢 Common area — CAM pass-through, pro-rata, grossed up for vacancy
🚪 Tenant suites — generally NOT CAM
📋 Tenant extras — billed direct to that tenant
⚠️ Periodic projects — never inside a recurring line
Because annual reconciliation is where most CAM disputes start, and tenants are told to demand itemised invoices.
Two numbers from our model of a 100,000 RSF building:
14% of the cleanable area is common area
22–23% of the labour is common area
Allocate on floor area and you under-recover by a third.
And the slowest space per sq ft in your whole building? 🛗 The elevator cab. 500–700 sq ft/hr. Nobody counts it.
