How to explain a CAM increase to a commercial tenant
Show what changed, connect the increase to expense categories, and communicate without overwhelming the tenant.
A tenant usually does not need every accounting line to understand a CAM increase. They need a clear comparison, the categories driving the change, the lease allocation basis, and a path for reasonable questions.
Lead with the answer
State the prior monthly or annual CAM amount, the new amount, the effective date, and the dollar and percentage change. Avoid beginning with pages of detail before the tenant understands the outcome.
Use a two-column comparison
Compare prior-year or current expense categories with the new actual or projected categories. Rank the largest drivers first. Taxes, insurance, utilities, repairs, landscaping, and security are easier to understand when shown side by side.
- Prior amount
- Current or projected amount
- Dollar change
- Plain-language reason
Explain the tenant’s share
Show the tenant’s premises, applicable pool, allocation percentage, and any relevant exclusions or caps. If the lease uses a fixed percentage or special pool, say so rather than implying the property uses one universal method.
Separate reconciliation from next-year estimates
A year-end reconciliation settles actual expenses against amounts previously billed. A next-year estimate changes the prospective monthly charge. They may be communicated together, but the calculations and effective dates should remain distinct.
Keep a review trail
Save the report, source categories, notice, delivery status, and any resulting agreement or waiver in the tenant record. If a provision is disputed, pause collection escalation and obtain appropriate lease or legal review.
