What NNN CAM Disputes Actually Cost You

Posted March 27, 2026 in Uncategorized

Triple net leases transfer operating costs to tenants. That is the underlying premise. What gets disputed is the execution: the calculation, allocation, and documentation of common area maintenance charges and whether the landlord’s accounting reflects what the lease actually requires.

For retail tenants, office occupants, and medical or dental practices operating under NNN structures, CAM disputes rarely surface in year one. They accumulate. By the time a tenant triggers an audit, the overbilling may span three to five lease years.

What CAM Charges Actually Control

CAM charges in a triple net lease are not just a line item. They are a cost allocation mechanism that directly affects operating costs and, in any acquisition context, enterprise value. If you run a dental group or surgery center with multiple NNN locations and each carries a $15,000 annual overbilling, the aggregate exposure affects EBITDA and any trailing twelve-month calculation a buyer will apply. The dispute is rarely about whether CAM charges exist. It centers on:

• Whether the landlord is allocating costs consistent with the lease’s defined CAM exclusions
• Whether capital expenditures are being passed through as operating expenses
• Whether the gross-up calculation for a partially occupied building is being applied correctly
• Whether anchor tenant carve-outs are being honored

These are drafting issues first. If the lease language is ambiguous, the dispute becomes a contract interpretation fight with documentary evidence on both sides.

The Capital Expenditure Problem

Most well-drafted NNN leases exclude capital expenditures from CAM. The problem is that landlords sometimes reclassify capital repairs as maintenance to pass costs through. A roof replacement is categorized as ongoing maintenance. HVAC replacement is treated as a repair. This is where financial exposure concentrates.

A Denver business dispute lawyer handling NNN disputes will examine the lease’s definition of capital expenditures, the property’s maintenance history, and the depreciation schedule for major systems. That documentation review often shifts the negotiating position significantly before litigation begins.

Audit Rights and When to Use Them

Most NNN leases include audit rights. Most tenants never use them. Audit clauses typically require:

• Written demand within a defined window (often 90 to 180 days after the landlord’s annual reconciliation)
• Selection of a qualified auditor (some leases restrict to CPAs)
• Landlord access to supporting documentation

The deadline matters. Miss the audit window, and you waive the right for that lease year. If you manage a portfolio of locations, these deadlines belong in your standard lease administration calendar, not just your attorney’s file.

When an audit identifies overbilling, the response depends on the dollar amount, the landlord relationship, and the remaining lease term. A $40,000 recovery claim in year two of a ten-year lease with a landlord you want to work with long-term is a different calculation than the same claim in year eight.

When the Dispute Escalates to Litigation

CAM disputes move toward litigation when the landlord contests the audit findings, when the amount justifies the cost of proceedings, or when the landlord uses CAM non-payment as a basis for a default or eviction notice.

That last scenario creates operational disruption fast. A medical practice or specialty clinic cannot absorb a lease termination threat while managing regulatory compliance, provider agreements, and patient continuity. The dispute becomes a business crisis, not just a billing disagreement.

Volpe Law LLC works with businesses and medical operators on commercial lease disputes where the financial and operational stakes require a strategic response. That means analyzing the claim value, the litigation cost, and the business consequences before recommending a path.

Settlement Posture and Resolution Strategy

Most CAM disputes settle. The question is on what terms and at what stage in the process. Tenants with strong audit documentation and clear lease language supporting their position settle earlier and on better terms. Tenants who audit late, miss demand deadlines, or have ambiguous lease definitions have less room to work with.

The practical settlement range in a multi-year overbilling claim usually reflects three things: the documented overbilling amount, the cost of continued litigation, and what each party needs from the other going forward. Sometimes that is a lump-sum recovery. Sometimes it is a prospective cap on CAM charges or a lease modification negotiated alongside the monetary settlement.

A Denver business dispute lawyer who understands commercial real estate can help you quantify the claim, assess the landlord’s position, and structure a resolution that accounts for your business objectives, not just the legal outcome.
