CAM charges are one of the most misunderstood components of a franchise lease. Most operators pay them without questioning them — and some overpay for years before anyone looks closely at the math. These 20 questions cover the full range of what operators actually need to know.
What CAM Is and How It Works
Q1: What exactly are CAM charges?
CAM stands for Common Area Maintenance. In a commercial lease, CAM charges represent your proportionate share of the landlord's costs to operate and maintain the shared areas of a multi-tenant property — parking lots, landscaping, common hallways, building systems, lighting, and similar expenses. You pay a monthly estimate throughout the year and receive an annual reconciliation comparing actual costs to your estimates.
Q2: How is my CAM share calculated?
Your share is your rentable square footage divided by a denominator — typically the total rentable square footage of the property or a defined subset of it. That ratio is your pro-rata share, and it's applied to the total CAM pool to arrive at your annual charge. If you occupy 2,500 SF in a 50,000 SF center, your pro-rata share is 5%.
Q3: What is a CAM true-up?
A true-up is the annual reconciliation of estimated versus actual costs. If actual CAM costs for the year exceeded your monthly estimates, you owe the difference. If your estimates exceeded actual costs, you receive a credit. True-ups are delivered by landlords typically within 90–120 days after year-end.
Q4: What's included in the CAM pool?
It depends entirely on your lease. Most leases include cleaning and janitorial, landscaping and snow removal, parking lot maintenance, common area lighting and utilities, security, property management fees, and insurance. Your lease should list what's included and — equally important — what's excluded.
Q5: Can the landlord include whatever they want in the CAM pool?
No. The CAM pool is defined by your lease. Charges not authorized by the lease provisions are not valid pass-throughs regardless of whether the landlord incurred the cost. This is the most fundamental principle of CAM dispute rights.
How CAM Errors Happen
Q6: Why do landlords overbill on CAM?
Most overbilling is not intentional. Property management companies use standardized billing software configured for their standard contract terms, which may not match the specific provisions in your lease. Management fee calculation errors, denominator errors, and capital expense categorization issues are almost always template problems, not fraud.
Q7: What are the most common CAM errors in franchise leases?
The management fee calculation error is the most common — specifically, applying the management fee percentage to a base that includes expense categories the lease explicitly excludes (taxes, insurance, capital reserves). Denominator errors (usually related to anchor tenant exclusions) are the second most common. Capital expenses billed as maintenance are the most variable in dollar amount.
Q8: How would I know if I'm being overbilled?
You wouldn't know without comparing the reconciliation line by line against your lease provisions. A large true-up doesn't necessarily mean overbilling — it could reflect legitimate cost increases. The only way to determine whether charges are accurate is to verify the calculation methodology, the denominator, the expense categories, and the cap provisions against your specific lease.
Audit Rights and Dispute Process
Q9: Do I have the right to audit my CAM charges?
Yes. Virtually all commercial leases include an audit rights clause that gives tenants the right to review the landlord's books and records supporting the reconciliation. The clause specifies the notice requirements, the window within which you must exercise the right, and what documentation the landlord is required to provide.
Q10: How long do I have to dispute a reconciliation?
It depends on your lease. Most commercial leases provide 1–3 years from the date the reconciliation is delivered to the tenant. After that window closes, your dispute rights for that year are contractually forfeited. Check your specific lease audit rights provision.
Q11: If I've already paid the reconciliation, can I still dispute it?
Yes, in most cases. Payment of a reconciliation does not waive your audit rights unless your lease contains an explicit payment-as-waiver provision, which is uncommon. The audit window runs from reconciliation delivery, not from payment. Paying first, then auditing, is a completely legitimate sequence.
Q12: Can I refuse to pay the true-up while I'm auditing?
No. Your dispute rights don't permit you to withhold payment of undisputed amounts. You are required to pay amounts as billed while a dispute is pending, unless your lease provides otherwise. File the dispute in writing, continue paying, and resolve the dispute through the formal process.
Q13: What happens if I miss the audit window?
The overcharges for that year become permanent. There is no appeal process once the contractual audit window closes. The most effective risk management is auditing every reconciliation promptly — before the window narrows.
Specific Situations
Q14: Can the landlord change CAM categories mid-year?
No. The CAM categories are defined by your lease. The landlord cannot unilaterally change which expenses are included in the CAM pool during the lease term without a lease amendment that you've agreed to. If a new expense category appears in your reconciliation that wasn't present in prior years, request the lease provision that authorizes it.
Q15: What if my landlord says they're charging what they charge everyone else?
What the landlord charges other tenants is irrelevant to your lease. Your obligations are defined by your specific lease agreement, not by what other tenants pay. Different tenants in the same building often have materially different CAM provisions, particularly in older buildings with long lease histories.
Q16: Can I negotiate CAM charges retroactively?
You can dispute CAM charges retroactively within the audit window by identifying specific calculation errors or unauthorized expenses. "Negotiation" is the wrong frame — it's a dispute of billed charges that don't match the lease. Retroactive voluntary adjustments by the landlord without a dispute are rare.
Q17: What if I think the management fee is too high but it matches the percentage in my lease?
If the percentage matches but the base is wrong (e.g., the management fee percentage is correct but it's being applied to gross expenses instead of controllable expenses), that's a calculation error you can dispute. If the percentage matches and the base matches and the calculation is correct, the management fee is accurate per your lease terms — even if you think the percentage is commercially unfavorable. Unfavorable terms are negotiable on renewal, not disputable as errors.
Q18: What if I signed a gross lease — do CAM charges apply?
Gross leases are supposed to be all-inclusive — the base rent covers operating costs and the landlord doesn't pass CAM through to tenants. However, many leases described as "gross" in practice include operating expense pass-throughs above a base year stop, tax escalations, or insurance pass-throughs. Review what your lease actually says in the operating expenses section, not just how the lease was described at signing.
Q19: What should I do if I can't pay the full true-up by the deadline?
Contact your landlord in writing before the deadline. Explain the situation and propose a payment plan. Document the landlord's response. Do not just miss the deadline without communicating — a true-up payment that's past due can trigger default provisions in some leases. Separately, use the payment timeline as a reason to verify the reconciliation first: you shouldn't pay an amount you haven't confirmed is accurate.
Q20: If I find errors, what's the most effective way to recover the overcharges?
A written dispute letter citing the specific lease provision, stating the billed amount and the contractually correct amount, and requesting a credit. Send it certified mail. Set a 30-day response deadline. Follow up in writing if you don't receive a substantive response. For amounts over $25,000 or landlords who refuse to respond, involve a commercial real estate CPA or attorney. The key in all cases: everything in writing, nothing verbal-only.
