Do Other Franchisees Audit Their NNN Charges?
Short answer: yes. Some franchisees do audit their NNN charges. Most do not. The ones who do tend to be multi-unit operators or franchisees who have already been through a surprise reconciliation and decided they wanted more visibility.
If you are asking the question, you are probably in the second category. Something in your statement looked off, or the number was larger than you expected, and you want to know whether other people actually bother checking this.
They do. Here's what that looks like.
What an NNN audit actually involves
An NNN (triple net) lease makes tenants responsible for a pro-rata share of property taxes, building insurance, and common area maintenance costs. Each year, the landlord reconciles actual expenses against what tenants paid in monthly estimates.
An NNN audit reviews that reconciliation for three things:
Math errors. Did the landlord apply the right pro-rata share percentage? Were the totals calculated correctly? Was the management fee applied to an appropriate base?
Lease compliance. Does what the landlord billed align with the CAM definition in your lease? Most leases include an exclusions list: things the landlord is not allowed to pass through to tenants. Capital expenditures, executive salaries, leasing commissions, and work on vacant spaces are common exclusions. If any excluded costs appear in the reconciliation, you have a legitimate dispute.
Documentation support. Can the landlord back up the numbers with actual invoices, expense records, and occupancy calculations?
A proper NNN audit looks at all three. It is not just checking the math, and it is not just asking "does this feel high."
Why most franchisees do not audit
It is not because they think everything is correct. It is usually one of three things:
They do not know auditing is an option. Most franchisees sign their lease, receive reconciliations, and pay them. No one told them they have a contractual right to inspect the supporting records. The lease includes this right, typically in an "audit rights" or "tenant's right to review" clause, but it is rarely highlighted at signing.
They think it is expensive. Historically, a full CAM audit required hiring a commercial real estate accountant or attorney. For a $3,000 to $5,000 dispute, paying $2,000 in audit fees made the economics questionable.
They worry about the landlord relationship. This is real. Franchisees in long-term leases at a center they depend on may be reluctant to push back on a landlord they need to renew with. That concern is legitimate. But the answer is usually to make the dispute professional and documentation-based rather than adversarial, not to skip it entirely.
Here's the thing: most franchise leases have audit windows of 60 to 180 days. If that window closes without you exercising your rights, you waive them regardless of whether the charges are correct.
What makes multi-unit operators more likely to audit
Multi-unit franchisees have more to gain from systematic auditing. If you have five locations with the same landlord or the same lease structure, a billing pattern that appears at one location probably appears at others. A management fee calculated on the wrong base at one location is likely calculated the same way at every location.
That multiplier effect makes auditing economically much more attractive. A $4,000 finding per location across five locations is a $20,000 recovery.
Even for single-unit operators, the economics work when the reconciliation amount is significant. A $10,000 true-up on a lease where your annual CAM estimate was $15,000 is worth scrutinizing.
What CAMAudit offers franchisees
I built CAMAudit to lower the barrier to entry on this analysis. You upload your lease and reconciliation statement. The tool runs 14 detection checks covering the most common NNN overcharge categories: management fee calculation errors, pro-rata share issues, CapEx misclassification, insurance overcharges, and others.
You get a finding summary without needing to hire an accountant or attorney to do the initial screening work. If the scan turns up findings, you have a documented basis for a dispute. If it does not, you have confirmation that the numbers look clean and you can pay the bill with more confidence.
The free scan is a reasonable starting point for any franchisee looking at a reconciliation they are not sure about.
