Can You Recover CAM Overcharges After the Audit Window Closes?
You missed the audit window in your lease. Maybe you didn't know the clock was running. Maybe you were dealing with other priorities. Maybe you received a reconciliation statement that looked reasonable on its surface and filed it away. Now you're looking at it more carefully and something is clearly wrong — but the 12 or 24 month audit window has closed.
Is your recovery claim gone?
Not necessarily. Your lease's audit rights window and your state's statute of limitations are two independent legal frameworks. In some states, under some circumstances, you may have more time than the lease clause suggests.

Step-by-Step: Evaluating Your Options After the Audit Window
1. Understand the two deadlines and recognize they operate independently.
The lease audit window is a contractual deadline written into your CAM reconciliation clause. It governs your right to use the lease's audit mechanism — the right to inspect books, request documentation, and trigger the reconciliation review process defined in the contract. Missing this window typically extinguishes your audit rights under the lease for that specific year.
The state statute of limitations is a separate legal deadline that governs when you can file a lawsuit for breach of contract. State SOL periods for written contracts vary widely: Illinois 10 years, New York 6 years, Florida 5 years, California 4 years, Texas 4 years, Colorado 3 years. These run from the date of the alleged breach — in most cases, from when the overcharge was billed and paid.
These two clocks are not the same. Losing one does not necessarily mean losing the other.
2. Recognize that missing the lease window may not extinguish state law claims.
Courts in several jurisdictions have held that a contractual audit deadline limits the tenant's right to use the lease's specific audit mechanism — not the tenant's right to bring a common-law breach of contract claim for the same overcharge. The reasoning: the lease says you have X months to audit; it doesn't say you waive all legal remedies if you miss that window.
This distinction is not universal. Some leases include express waiver language stating that failure to audit within the window constitutes final acceptance of the reconciliation. If your lease says that, the analysis is different. Read your lease carefully before assuming the lease window is your only deadline.
3. Check whether your state has a discovery rule.
The discovery rule is a doctrine in many states that tolls — pauses — the statute of limitations until the plaintiff discovered, or reasonably should have discovered, the overcharge. In plain terms: if the clock doesn't start until you knew (or should have known) about the problem, a reconciliation error that was buried in opaque accounting may not have started the SOL clock on the date you paid.
States that have applied the discovery rule in commercial contract contexts include Massachusetts, New Mexico, Alaska, and others. The availability and scope of the discovery rule varies significantly by state and by the specific facts of the case. Whether the rule applies to a CAM billing dispute in your state is a legal question, not an accounting question.
4. Document when you discovered the overcharge.
If you're relying on the discovery rule, timing matters. Write down: when you first received the reconciliation, when you first reviewed it in detail, what specifically you discovered, and how you discovered it. This documentation establishes the start of your discovery rule clock if that argument becomes relevant.
5. Check for fraudulent concealment.
Some states toll the SOL when the defendant actively concealed the wrongdoing. If your landlord misrepresented a CAM charge — claiming a cost was CAM-eligible when they knew it was excluded, or providing intentionally misleading backup — that concealment may extend your window. This is fact-intensive and requires legal review.
6. Consult a commercial real estate attorney for amounts that warrant the cost.
For overcharges above $25,000 — particularly multi-year structural errors like a wrong base year or a systematic pro-rata share miscalculation — an attorney consultation is worth the investment. Expect $300–$600 for an initial consultation that tells you whether you have a viable claim outside the lease window.
7. Focus first on years clearly within both windows.
Work through years clearly within both the lease audit window and your state SOL first. Those are your strongest claims and fastest path to recovery. Documentation from those years also supports the argument about earlier ones.
8. Use CAMAudit to scope the overcharge before hiring an attorney.
If you're trying to decide whether it's worth engaging an attorney, you need a realistic estimate of what's at stake. CAMAudit's 14-rule scan runs on your lease and reconciliation for $79 and identifies specific overcharges with calculations. That output — the specific error types, the dollar amounts, the lease citations — is exactly the kind of scoping information an attorney needs to advise you. Walk into that consultation with a documented finding, not a general suspicion.
"I built CAMAudit specifically for situations like this — where a tenant suspects something is wrong but doesn't know what or how much. Scoping the overcharge first lets you make a rational decision about whether to engage counsel." — Angel Campa, Founder of CAMAudit
An Honest Assessment of the Limits
Missing the lease audit window creates real risk. Even in states with favorable discovery rules or long SOL periods, a landlord's first defense will be the contractual audit deadline. Courts enforce lease provisions, and arguing around a clear contractual waiver is harder than arguing within a lease window.
Recovery after a closed audit window is most viable when: the lease's waiver language is ambiguous or absent; the state has a discovery rule and you had no reason to know about the overcharge until recently; or the overcharge resulted from active misrepresentation by the landlord.
It is least viable when: the lease includes clear "acceptance upon payment" language; the error was apparent on the face of the reconciliation; or your state has a short SOL and the overcharge is old.
Common Mistakes After Missing the Audit Window
- Assuming the claim is dead without checking. The lease window and state SOL are different clocks. Check both before concluding you have no options.
- Waiting even longer after discovering the issue. Every day you wait after discovering the overcharge potentially erodes your discovery rule argument. Act promptly once you identify the problem.
- Filing a claim without legal review for post-window years. This is not a DIY situation for years outside the audit window. The procedural and legal complexity warrants professional guidance.
- Neglecting in-window years to focus on out-of-window years. Recover what you can under the lease's standard mechanism first — that's your strongest position and it funds any subsequent legal effort.
Frequently Asked Questions
What's the difference between the audit rights window and the statute of limitations?
The audit window is a contractual provision — it gives you a specific time period to use the lease's built-in audit mechanism. The statute of limitations is a state law concept — it governs how long you have to file a court claim. They operate independently. See also: CAM statute of limitations guide.
If I missed the audit window by a few months, is there any argument for relief?
Possibly. Some courts apply equitable doctrines like estoppel if the landlord's conduct contributed to the delay — for example, if the landlord delayed producing documents during the audit period in a way that prevented timely completion. These are fact-specific arguments. Consult a CRE attorney if the dollar amount warrants it and the landlord's conduct was a contributing factor.
Does the discovery rule apply automatically, or do I have to argue for it?
You have to affirmatively raise it. The discovery rule is not automatic — you must present facts establishing that you could not reasonably have discovered the overcharge until the date you claim. Undocumented assertions ("I just noticed it") are weaker than documented facts ("the error was embedded in a line item described as 'occupancy adjustments' that did not signal the specific error on its face").
