CAM, or common area maintenance, charges are a tenant’s share of the costs to operate shared areas of a commercial property. Understanding how they are calculated is just as important as understanding the base rent.
What CAM Charges Can Cover
CAM charges commonly cover work and services that benefit more than one tenant, such as landscaping, parking lot upkeep, exterior lighting, security, and janitorial service for common spaces. The exact list should be defined in the lease.
Questions to Ask Before You Sign
Ask for a history of CAM charges, the current year budget, and an explanation of how your share is calculated. It is also worth asking whether the lease places a cap on annual controllable operating expense increases.
Compare Total Occupancy Cost
A lower base rent does not always mean a lower total cost. Compare base rent, CAM, taxes, insurance, utilities, and any other pass-through expenses across each option so you can evaluate the real annual commitment.
