How do landlords inflate CAM charges — and what should I look for?
The short answer
Tenants commonly report CAM reconciliation bills that are higher than expected, and industry sources identify several areas where disputes frequently arise: overly broad CAM definitions that allow capital costs or management markups to enter the pool, denominator manipulation in the pro-rata share calculation, and administrative fees stacked on top of already-pooled costs. Whether any given reconciliation reflects a genuine cost versus an overreach depends on what your lease's CAM definition allows. The cap structure matters too: a controllable CAM cap limits landlord-driven management and maintenance costs but typically does not apply to uncontrollable items like taxes and insurance. Scan your lease to see how the CAM definition, the cap, and the exclusion list are drafted before you sign.

Areas where CAM reconciliation disputes commonly arise
Tenants and industry commentators identify several recurring patterns. First, capital expenditures — roof replacement, parking lot repaving, HVAC upgrades — appearing in the CAM pool when the lease's exclusion list does not clearly prohibit them. Second, management fees expressed as a percentage of all property revenues, which can grow independently of actual management work. Third, denominator manipulation: if the CAM is divided by occupied square footage rather than total leasable area, a partially-vacant building pushes a larger share onto each occupied tenant.
A fourth area involves administrative or supervisory markups applied on top of vendor invoices — fees that can double a cleaning or landscaping bill. Tenants who request and review the underlying invoices during an audit often find discrepancies between what vendors charged and what appeared in the reconciliation. None of these practices are necessarily improper depending on the lease language, which is why the CAM definition is one of the highest-value clauses to negotiate.
The controllable vs. uncontrollable cap distinction
A commonly negotiated protection is a CAM cap — a limit on annual increases. But caps typically apply only to 'controllable' expenses: management fees, maintenance, and administrative costs that the landlord can influence. 'Uncontrollable' items — property taxes, insurance, and sometimes utilities — are often explicitly excluded from the cap, meaning they can increase without limit. Tenants who negotiate a 3% or 5% annual cap may be surprised when taxes and insurance drive reconciliation bills above that cap in a given year. The lease should clearly state which expenses are controllable and subject to the cap, and which are not.
What to look for in your lease
- An explicit exclusion list that removes capital expenditures, leasing commissions, and above-grade structural repairs from CAM.
- Whether the pro-rata denominator is total leasable area or occupied area — total leasable is the tenant-favorable version.
- A cap on controllable CAM increases, and the precise definition of 'controllable' versus 'uncontrollable' expenses.
- Management fee caps — a common structure is capping the fee at a percentage of collected rents.
- Whether administrative or supervisory fees are included in or separate from the management fee definition.
Questions to ask before signing
- Ask the landlord for the last two years of actual CAM reconciliation statements and the supporting expense detail.
- Ask the other party to clarify whether capital expenditures are explicitly excluded from the CAM pool under this lease.
- Confirm whether the pro-rata share is calculated on total leasable area, and get the current occupancy figures.
- Consider having the lease reviewed to verify that the CAM exclusion list and controllable cap language are tenant-protective.
Why scan instead of guess
The general rule tells you the baseline. Your lease tells you what you’re actually being asked to sign — and the wording is what binds. Dang reads the document and flags the clauses worth reviewing, in plain English.
The deterministic engine scores and decides what’s risky. The AI only enriches the plain-English wording — AI extracts, code decides, never the other way around.

Common questions
Can I challenge a CAM reconciliation I think is wrong?
The mechanism for doing that is typically an audit rights clause in the lease. If your lease includes an audit right, it will specify a notice window — commonly 30 to 90 days after receiving the reconciliation statement — during which you can request to review the landlord's books. Scan your lease for audit rights language and the applicable deadline.
What is the difference between a controllable and uncontrollable CAM expense?
A commonly seen distinction: 'controllable' expenses are items the landlord can influence through management decisions, such as maintenance contracts, management fees, and administrative costs. 'Uncontrollable' expenses are those tied to third-party obligations the landlord cannot easily limit, such as property taxes, insurance premiums, and utility costs. Caps on CAM increases typically apply only to the controllable portion.
Are CAM disputes common?
Industry sources describe CAM reconciliation disputes as a frequently reported friction point between commercial landlords and tenants, particularly in NNN retail and office leases. The lease's definitions are the primary factor in how disputes are resolved.
