A CAM charges dispute in a commercial lease usually comes down to one question: does the lease let the landlord bill that cost to you? Common area maintenance (CAM) charges cover your share of upkeep for shared spaces. Operating expenses cover wider building costs passed through the same way. When a bill doesn’t match the lease, the answer sits in the contract language and the landlord’s records. This page explains how these charges are built, what tenants usually challenge, and how a dispute moves forward in Florida.
What CAM and operating expense charges are
CAM and operating expense charges are a tenant’s share of the costs a landlord pays to run a building. Shared-area costs include parking lots, sidewalks, landscaping, exterior lighting, and common hallways. Operating expenses can also include insurance and property taxes.
You’ll see these charges most often in retail, office, and industrial leases. In a triple net (NNN) lease, the tenant pays a share of most building costs on top of base rent. In a modified gross lease, base rent covers some costs, and the tenant pays extra only for certain costs or increases. Read the lease definition, not the label on the invoice.
This page is for three kinds of readers: tenants holding a year-end reconciliation statement they don’t understand, owners reviewing a lease before signing, and partners or managers who handle property costs.
Ayala Law PA focuses on business and commercial litigation, contract disputes, and real estate litigation in Florida courts and arbitration. CAM and operating expense disputes fall within that work.
If a reconciliation statement has your business paying charges you can't explain, our team can review the lease with you and talk through your options. Talk it through with our team — we can walk you through how a situation like yours is usually handled and what your options are.

How CAM charges are calculated and what the lease says
CAM charges are usually set in two steps: monthly estimates during the year, then a year-end true-up. The landlord collects the estimates. After the year closes, it compares those payments with actual costs and sends a reconciliation statement. You owe any shortfall, and the lease governs any overpayment.
Your share is your pro rata share, usually your leased square footage divided by the total leasable area. Several lease clauses control the numbers:
- Operating expense definition: the costs the lease allows the landlord to bill.
- Exclusions: items such as capital improvements, leasing commissions, and landlord marketing that the lease may leave out.
- Base year or expense stop: a starting point, so you pay only increases above it.
- Management fee cap: a limit on the landlord’s management charge.
- Audit rights and objection deadline: how you check the numbers and how long you have to object.
- Fee and dispute terms: whether the lease awards attorney’s fees and whether disputes go to court or arbitration.
A contract needs offer, acceptance, consideration, and essential terms stated clearly enough (St. Joe Corp. v. McIver). Where an express contract covers the same subject, claims from that relationship will not support unjust enrichment (Williams v. Johnson). If the lease has a fee clause, a court may allow reasonable fees to the side that prevails on the contract (Fla. Stat. § 57.105).
Common reasons tenants dispute CAM charges
Tenants usually challenge charges the lease does not clearly allow. Five problems come up again and again.
- Lump-sum increases: a big jump with no line items, invoices, or ledger detail.
- Excluded costs: capital work, leasing commissions, or the landlord’s own overhead billed as operating costs.
- Pro rata errors: the wrong square footage, or a denominator that counts space you don’t share.
- Duplicates and extra fees: the same invoice billed twice, admin fees above the lease cap, or services you never receive.
- Wrong year or wrong formula: costs from another year, or a management fee that doesn’t follow the lease formula.
The paper usually decides these disputes. A clear lease definition and a complete ledger give you something concrete to test. A vague statement and a lump total do the opposite. The costliest habit is paying without checking. A tenant who pays a statement can lose the chance to object within the lease’s time limits.
Steps to take before a dispute becomes a lawsuit
Start by reading the lease and writing down the objection deadline. A missed notice period can limit your options.
- Calendar the deadline for objecting and for any audit request.
- Request backup in writing: invoices, ledger detail for each disputed category, and the square footage used. Keep every request and reply.
- Compare each charge with the lease definition, prior statements, and the pro rata math.
- Object in writing. Name each line item, the amount, the lease section you rely on, and the records still missing.
- Keep paying undisputed amounts on time. Many leases treat late or withheld payment as a default, so review the default terms before you stop paying anything.
Florida’s limitations statute sets time limits for filing suit (Fla. Stat. § 95.11). Calendar that date alongside the lease deadline.
How a CAM dispute moves forward
A CAM dispute usually moves from document review to a written demand, then to audit or formal resolution. Each step depends on the lease.
- Intake: You share the lease, amendments, statements, and correspondence. Ayala Law PA reviews the dispute against that language.
- Demand and negotiation: A written demand lists the disputed amounts and asks for a corrected statement, credit, or refund. Many disputes end here.
- Audit or records review: If the lease gives audit rights, the review follows the lease’s procedure.
- Formal resolution: If the matter stays open, it may go to court or to arbitration.
Florida law says actions shall be brought only in the county where the defendant resides, where the cause of action accrued, or where the property in litigation is located, but this section does not apply to actions against nonresidents (Fla. Stat. § 47.011). For a property in Hillsborough County, the property location is one permitted place.
If the lease requires arbitration, Florida law treats that agreement as valid and enforceable, except on grounds that allow a contract to be revoked (Fla. Stat. § 682.02). A court may not refuse to order arbitration just because the claim lacks merit (Fla. Stat. § 682.03).
Settlement offers follow their own rules. Fla. Stat. § 45.061 provides that a written offer under that section shall not be filed with the court and shall remain open for 45 days unless withdrawn sooner by a writing served on the offeree prior to acceptance by the offeree, though by its own terms the section does not apply to causes of action that accrue after its effective date. Florida law also makes evidence of a compromise offer on a claim disputed as to validity or amount, and statements made in compromise negotiations, inadmissible to prove liability or the value of a claim (Fla. Stat. § 90.408).
Timing varies with the lease, the amount in dispute, the landlord’s records, and the court or arbitration calendar. No single timeline fits every case.

Common questions about CAM disputes in Florida
Can a tenant dispute a CAM charge after paying it?
That depends on the facts, mainly the lease’s objection deadline and audit terms. Act within those terms.
Does the landlord have to show receipts?
Many leases give tenants records or audit rights. The lease decides what the landlord must provide, so ask for the backup in writing.
Can a tenant stop paying while a CAM dispute is pending?
Stopping payment may put the lease in default. Review the default terms first, and keep paying the amounts you don’t dispute.
Is a CAM dispute the same as an eviction?
No. A CAM dispute is about money owed under the lease. Possession of the space is a separate question.
