Before getting into the tenant retention connection, it helps to establish a shared understanding of the cost structure involved. When exploring what are CAM fees in commercial real estate, the answer starts with the lease. CAM stands for Common Area Maintenance, and these fees cover the landlord’s costs for maintaining shared spaces throughout a commercial property. Common expenses include:
- Parking lots and exterior lighting
- Lobbies and common-area corridors
- Landscaping and grounds maintenance
- HVAC systems serving areas outside individual tenant suites
In most commercial leases, particularly triple net (NNN) and modified gross structures, tenants pay a proportionate share of these costs on top of their base rent. The challenge is that CAM charges are variable by nature. They shift year to year based on actual vendor costs, repair needs, seasonal factors, and how expenses are allocated across tenants. That variability is not inherently a problem. The problem is what happens when tenants have no framework for understanding it, and no one takes the time to provide one.
