CAM Charges Explained (Common Area Maintenance)
What common area maintenance really covers — and how tenants keep it in check.
What are CAM charges?
CAM charges — common area maintenance charges — are a commercial tenant's proportionate share of the cost of maintaining the shared areas of a property: parking lots, lobbies, hallways, landscaping, lighting, and similar. They are billed on top of base rent, most often in net and modified gross leases.
What CAM typically covers
- Parking lot upkeep, snow removal, and lighting;
- Landscaping and exterior cleaning;
- Common-area utilities, security, and management fees; and/or
- Repairs and maintenance of shared building systems.
What counts as CAM — and whether big-ticket capital items can be included — is defined entirely by the lease, which is why the definition deserves close attention.
How CAM is calculated and reconciled
The tenant usually pays estimated monthly CAM, and the landlord reconciles actual costs at year-end, billing or crediting the difference. The tenant's "proportionate share" is typically its square footage divided by the building's leasable area — though "gross-up" provisions can change that math in a partly vacant building.
What tenants should negotiate
Smart tenants negotiate a cap on annual increases in controllable expenses, exclusions for capital repairs and landlord overhead, and the right to audit the landlord's CAM statements. These protections belong in the broader commercial lease negotiation.
