See How It WorksSee a sample report firstColorado's commercial real estate market has expanded fast. Denver's downtown office corridors, the retail strips along Colorado Boulevard, the power centers in Aurora and Thornton, the suburban parks in the Denver Tech Center — all of them run on triple-net and modified-gross leases that pass common area maintenance costs to tenants. And wherever CAM charges flow, billing errors follow.
40% of CAM reconciliations contain material errors (Tango Analytics / PredictAP, 2023)
That 40% figure is not abstract. When I built CAMAudit and ran reconciliation samples through the detection pipeline, management fee overcharges, pro-rata share miscalculations, and capital expenditure items buried in operating expense pools showed up consistently — including in statements from well-known Colorado property management firms. If you are a commercial tenant in Colorado paying CAM, there is a real chance you are paying more than your lease requires.
The good news: Colorado law gives you a recovery window. The bad news: that window is shorter than most tenants realize.
Colorado's statute of limitations for written contract claims is 3 years under Colo. Rev. Stat. § 13-80-101. The clock generally starts running from the date of each breach — meaning each disputed CAM charge or overpayment starts its own 3-year period.
Three years is not a long window for a CAM reconciliation cycle that typically runs 12–18 months after the lease year ends. If your landlord issued a 2023 reconciliation statement in mid-2024, your clock on disputing those charges runs through mid-2027. Charges billed before April 2023 may already be time-barred.
The practical implication: do not wait until the end of your lease to audit. By then, years of potentially recoverable overcharges may already sit outside the limitations period.
Colorado has no state statute granting commercial tenants a right to audit CAM records. Your audit rights exist only if your lease negotiated them. A well-drafted audit clause will typically include:
If your lease lacks an explicit audit clause, you can still demand documentation supporting each charge. Under Colorado contract law, the landlord bears the burden of proving CAM charges are within the lease's authorized scope. You simply may not have the formal right to walk into their accounting office and inspect the underlying ledger.
Denver-area commercial real estate is heavily managed by regional and national property management companies. Their CAM reconciliation systems are sophisticated — but that does not mean the outputs are accurate. Our tool has flagged several recurring patterns in Colorado-style statements.
Most Colorado retail and office leases cap the management fee at 3–5% of gross revenues or operating expenses. Landlords sometimes calculate the fee base incorrectly — including excluded items like taxes, insurance, or capital expenditures in the denominator, inflating the fee in absolute terms. CAMAudit's management fee detection rule flags any fee percentage that, when traced back to the allowed base, exceeds the lease cap.
Your pro-rata share should be your leased square footage divided by the total leasable area of the property. In Colorado strip centers and mixed-use buildings — common along Colfax Avenue or in Denver's Highlands neighborhood — landlords sometimes exclude anchor tenant space from the denominator, inflating every other tenant's share. Failing to update the denominator after major tenants vacate has the same effect. A 1-point pro-rata error on a $200,000 annual CAM pool adds $2,000 per year directly to your bill.
Many Colorado retail leases negotiated after 2010 include CAM caps limiting annual increases to 5–8% over the prior year's controllable expenses. Landlords occasionally apply the cap to the wrong base year, reset the cap clock mid-lease, or exclude expenses from the cap calculation that the lease intended to include.
Colorado landlords, particularly those managing aging strip centers in Aurora, Lakewood, and Englewood, sometimes pass roof replacement, HVAC overhaul, or parking lot repaving costs through the CAM pool as a lump sum. Lease language typically requires that capital expenditures be amortized over their useful life — and many leases exclude them from CAM entirely. A lump-sum CapEx appearing as a CAM line item is a significant red flag.
For gross leases with expense stops, the base year calculation controls what you pay above the stop. If a landlord uses an artificially low base year — one with below-normal occupancy or deferred maintenance — every subsequent year's pass-through is inflated relative to what it should be.
Under occupancy-adjusted gross-up provisions, variable expenses like cleaning and utilities are supposed to be normalized to a standard occupancy level (commonly 90–95%). If the landlord fails to gross up in low-occupancy years, each tenant absorbs a larger share of fixed costs than the lease contemplates.
Colorado's commercial CAM dispute process is contractual, not regulatory. There is no administrative agency that handles these disputes and no mandatory mediation scheme. What you have is your lease and the courts.
Step 1: Read your lease's audit clause. Identify the deadline for contesting the reconciliation statement. Many leases require you to object in writing within 90 or 180 days of receiving the statement. Missing this deadline may waive your dispute rights regardless of the statutory SOL.
Step 2: Request supporting documentation. Write to your landlord via certified mail requesting the general ledger, invoices, and allocation schedules underlying the annual reconciliation. Your letter should reference the specific line items you are contesting and the lease provisions you believe have been violated.
Step 3: Run a systematic audit. Upload your lease and the CAM statement to CAMAudit. The platform runs all 14 detection rules — management fee, pro-rata share, cap analysis, CapEx classification, base year verification, gross-up check, and more — and returns a structured findings report. The report identifies specific overcharges with the lease language and calculation showing why each item is improper.
Step 4: Send a formal dispute letter. The dispute letter draft should cite your lease provisions, attach or reference the supporting calculations, quantify the claimed refund, and set a 30-day response deadline. Send via certified mail with return receipt to preserve delivery evidence. Colorado courts require proof of notice; certified mail is the conventional standard.
Step 5: Negotiate or escalate. Most Colorado landlords respond to a well-documented demand within 30–60 days. Many overcharges settle without litigation — landlords generally prefer a credit or refund to the cost of defending a breach-of-contract claim. If the landlord refuses to respond or rejects the dispute without substantive explanation, filing in Colorado District Court may be necessary. At that point, a real estate attorney should take the lead.
The typical Colorado CAM dispute follows a predictable arc. Within 30 days, your landlord's property management team usually acknowledges the letter and requests additional time to respond. A substantive response follows in 30–90 days. That response will either concede specific line items, offer a partial credit, or reject the claim outright with a counter-explanation.
If they concede, you negotiate the amount and form of credit — typically applied to future rent or refunded as a check. Document the settlement in a written amendment or letter agreement.
If they reject, evaluate the strength of your documentation. A dispute supported by CAMAudit's findings report, with clear citations to lease language and arithmetic, is significantly easier to litigate than a bare allegation of overcharge. Colorado courts apply standard contract interpretation principles: the lease language controls, and the landlord bears the burden of proving each charge is authorized.
Colorado's prejudgment interest rate on money judgments is 8% per annum under Colo. Rev. Stat. § 5-12-102. If you prevail in litigation, interest accrues from the date of each overpayment — which, over a multi-year dispute, adds meaningful dollars to the recovery.
No. Colorado has no state statute specifically governing commercial CAM expense pass-throughs or granting statutory audit rights to commercial tenants. The Colorado Residential Landlord-Tenant Act (Colo. Rev. Stat. § 38-12-101 et seq.) applies only to residential tenancies. Commercial tenants rely entirely on their lease language and general contract law. This makes the audit clause in your lease, and the quality of your initial lease negotiation, critical to your ability to recover overcharges.
Two deadlines apply simultaneously, and the shorter one controls. First, check your lease — most commercial leases contain a contractual challenge period (commonly 60–180 days after the reconciliation statement is delivered) after which you waive the right to dispute. Second, Colorado's statutory SOL is 3 years under Colo. Rev. Stat. § 13-80-101. You must act before both windows close. If your lease says 90 days and you miss it, the statutory SOL does not save you.
Yes, but with limitations. Even without an explicit audit clause, you retain the contractual right to contest charges you believe are unauthorized. You can demand supporting documentation and dispute in writing. What you lose without an audit clause is the formal right to inspect the landlord's books — you may have to rely on what they voluntarily provide or pursue discovery in litigation. CAMAudit can flag mathematical and classification errors from the reconciliation statement itself, often without needing the full underlying ledger.
A CAM cap limits annual growth in the controllable portion of CAM to a fixed percentage (typically 5% compounded or non-compounded). To check compliance, you need: (1) the base year controllable expense total from which the cap starts, (2) the allowed percentage, and (3) whether the lease compounds or calculates the cap annually on a flat base. CAMAudit's CAM cap detection rule reconstructs the allowed trajectory from lease inputs and flags any year where actual controllable expenses billed exceeded the capped amount. The most common violation pattern is landlords moving items out of the controllable category to escape the cap ceiling.
