What they do not share — and what standard NNN and gross lease CAM provisions do not authorize — is the cost of running the landlord's corporate enterprise.
Yet landlord overhead regularly appears in CAM pools. It arrives not as a line item labeled "CEO salary" but embedded in "administrative costs," "property management fees," "asset management services," and "technology platform fees." The disguise is often plausible. The billing is often illegal under the lease.

CAMAudit Rule 13 uses AI classification to flag line items matching known corporate overhead patterns. Here is the framework the classifier uses — and how you should apply it manually when reviewing a reconciliation statement.
Every expense in a CAM pool must clear one threshold question before anything else:
Was this cost incurred for the benefit of this specific property, or for the benefit of the landlord's corporate enterprise?
Property-level costs are recoverable. Corporate-level costs are not. The distinction is not about who writes the check or which entity appears on the invoice — it is about the economic purpose of the expenditure.
A staff accountant who spends 100% of her time on accounts payable for one shopping center is a property-level cost. The same accountant, working for the landlord's corporate accounting department across a 50-property portfolio, is a corporate-level cost — even if the landlord allocates a portion of her salary to each property.
CFO, CEO, COO, VP of Acquisitions, VP of Finance, and senior corporate counsel salaries appear in CAM pools labeled as "administrative overhead," "management administration," or "executive management services." The test: would this individual's work cease if this specific property were sold? If not, the cost is corporate.
Portfolio-level decisions (capital allocation, acquisitions, financing) benefit the landlord's enterprise, not the specific property. Salary for any executive whose responsibilities span the portfolio cannot be allocated to an individual property's CAM pool.
Landlord headquarters rent, corporate office utilities, and shared workspace costs for corporate staff are not property-level expenses. These appear as "office overhead," "administrative facilities," or are bundled into inflated management fee structures.
There is a legitimate category of property-level accounting: the bookkeeper who handles this property's ledger, processes this property's invoices, and prepares this property's financials. This is recoverable.
What is not recoverable: corporate controllers, treasury staff, tax specialists handling entity-level returns, and financial reporting staff serving the landlord's investor relations or SEC compliance functions. When the management company bills "accounting services" without itemizing which staff and what functions, the entire category warrants a breakdown request.
Property-specific insurance (property damage, general liability for the premises, property casualty) is recoverable. D&O insurance protects the landlord's corporate officers and directors from claims arising from their conduct as corporate fiduciaries — it has no relationship to the specific property. Corporate umbrella policies covering the landlord's enterprise at large are similarly non-recoverable.
Look for these in line items labeled "insurance," "liability coverage," or "risk management." The test is whether the policy insures the property or insures the entity and its principals.
Legal costs fall on a spectrum. On one end: property legal (tenant lease disputes, permit applications, contractor liens, zoning for this property) — fully recoverable. On the other end: M&A counsel for the landlord's portfolio acquisition, entity formation, securities compliance, partnership restructuring — fully non-recoverable.
In the middle: portfolio-wide lease form development, corporate litigation in which this property happens to be one of many defendants. The test is proportionality and nexus. When the landlord's corporate litigation invoice is allocated across properties, the tenant should receive the full invoice and the allocation methodology, not just their allocated share.
Property management software used to operate this building (work order systems, tenant portal, building automation) is a legitimate property-level cost. The landlord's enterprise-wide asset management platform, portfolio analytics system, investor reporting software, and corporate ERP system are not.
This category has grown materially as landlords have invested in institutional-grade technology platforms. The billing vehicle is typically "technology fee" or "software and systems." A request for the specific software titles and their function will distinguish property-level tools from enterprise infrastructure.
Marketing costs for a specific property — leasing commissions, advertising vacant spaces, property-specific signage — are borderline (some leases explicitly exclude marketing costs from CAM). What is clearly non-recoverable: corporate brand advertising, landlord-level marketing campaigns, PR and communications for the landlord's enterprise, and trade association memberships serving the landlord's corporate interests rather than tenant mix management at this property.
To avoid over-challenging legitimate charges, here is what standard NNN lease language does authorize:
The most structurally complex version of overhead pass-through involves a management company that charges the standard management fee AND separately bills corporate overhead items through the property's operating expense pool.
This creates a double-billing structure:
The management fee is supposed to include the management company's overhead for running this property. If the same management company (often an affiliate of the landlord) is also billing management-overhead costs as operating expenses, the tenant is paying for management infrastructure twice.
Audit trigger: when a property has both a management fee and line items for "administrative," "accounting," or "technology" services billed to the property separately, request an itemized breakdown of both. The management fee agreement (often an exhibit to the lease or available on request) will specify what it covers.
When a line item raises an overhead question, the challenge follows a structured sequence:
Step 1 — Request the invoice or cost allocation methodology. For any line item not supported by a third-party invoice, ask for the allocation basis. How was this cost assigned to this property? What is the denominator (square footage, property count, revenue)?
Step 2 — Request the organizational chart or cost center structure. For personnel costs, ask which employees' compensation is included and in what capacity. An org chart showing whether these roles report to a property-level or corporate-level hierarchy is highly probative.
Step 3 — Request the management fee agreement. If there is both a management fee and separate administrative line items, compare the management fee scope to the separately billed items for overlap.
Step 4 — Identify the nexus. For each challenged item, document why it fails the property-level test. "This policy number insures the landlord's enterprise, not this property" is a stronger challenge basis than "I think this is corporate overhead."
Standard NNN lease language — "operating expenses of the building" or "costs incurred in operating, maintaining, and repairing the property" — by its terms limits recovery to property-level costs. Courts interpreting these provisions consistently hold that corporate overhead costs are not within the ordinary meaning of "operating the property." See Hous. Indus. Corp. v. GAF Corp. and similar commercial lease cases where courts have rejected landlord attempts to include corporate administrative costs in operating expense pools.
ICSC's Guide to Operating Expense Recoveries (commercial real estate industry standard) explicitly identifies corporate-level overhead as non-recoverable and notes that management fees, when charged, should be the exclusive vehicle for management company overhead recovery.
"After testing reconciliation samples from published audit cases through CAMAudit, the pattern is consistent: corporate overhead doesn't appear as a single large line item. It's distributed across five or six categories that each look plausible in isolation. The AI classifier in Rule 13 catches the pattern across the full reconciliation, not just the individual line." — Angel Campa, Founder of CAMAudit
Does "operating expenses of the property" include corporate overhead?
No, under the standard interpretive framework applied by courts and industry bodies. "Operating expenses of the property" is consistently construed to mean costs incurred to operate that specific property — not to run the landlord's corporate enterprise. Some leases contain broader language ("costs of the landlord's operations" or "costs allocated to the property by the landlord") that could support broader recovery. If your lease contains language like this, review it carefully and consult counsel, as it may shift the analysis.
What if the landlord self-manages?
Self-managed properties still need to establish which personnel costs are property-level versus corporate-level. A self-managing landlord who owns one property has straightforward allocation: virtually all personnel costs are property-level. A self-managing landlord who owns 30 properties must allocate corporate management costs using a documented methodology. The tenant is entitled to understand that methodology and challenge allocations that include corporate functions. Some self-managed landlords charge a "management fee" to the property even without a third-party manager — this is permitted if the fee is reasonable, but it cannot be layered on top of separate administrative overhead charges.
How do I request a breakdown of management costs?
Your audit rights clause gives you access to the books and records supporting the reconciliation. Send a written request (preserving the audit rights window in your lease — typically 12–24 months from receipt of the reconciliation) specifying the line items in question and asking for: (1) vendor invoices or internal allocation methodology; (2) identification of personnel whose compensation is included; (3) the management fee agreement if a management fee was charged separately. Frame the request as an audit rights exercise, not a dispute, to preserve flexibility.
At what dollar threshold is it worth disputing?
As a practical matter, overhead pass-through disputes under $5,000 often cost more to litigate than to recover — unless your lease has a fee-shifting provision for audit disputes (increasingly common in tenant-favorable markets). However, the threshold shifts in three situations: (1) the same landlord manages multiple properties you occupy; (2) you are approaching your audit rights window and want to preserve the claim; (3) the lease has a cumulative CAM cap and the overhead inflates the base against which future caps are calculated. In those cases, the downstream impact multiplies the recovery value substantially.
