What Should a CAM Dispute Letter Draft Include? (10 Required Elements)
TL;DR: An effective CAM dispute letter draft needs 10 elements: proper notice identification, a lease section citation, an overcharge summary table, line-item calculations, supporting exhibits, an audit rights invocation, the specific period under dispute, a clear resolution ask, a 30-day response deadline, and delivery by the method the lease requires.
CAM Dispute Letter Draft: A CAM dispute letter draft is a formal written notice from a commercial tenant to a landlord identifying specific overcharges in the annual CAM reconciliation, citing the relevant lease provisions, documenting the calculation of the overcharge, and requesting a specific remedy such as a credit or refund.
"CAMAudit generates the calculation that makes the dispute letter draft credible. After running a reconciliation through CAMAudit, tenants have the specific dollar figure, the lease provision violated, and the corrected calculation all in one place. That is the difference between a letter the landlord engages with and one that gets filed away." — Angel Campa, Founder of CAMAudit

A CAM dispute letter draft written without a checklist tends to be either too aggressive (threatening legal action before establishing the numbers) or too vague (stating a general belief in overcharging without a specific dollar claim). Both versions fail. The landlord needs enough information to verify your claim or dispute it specifically, and you need a letter that creates a paper trail if the dispute escalates.
Here are the 10 elements that matter.
1. Proper Notice Identification
The opening lines of the letter establish jurisdiction over the dispute. Include:
- Full legal name of your business entity
- Property address and suite/unit number
- Lease date and any controlling amendments
- The reconciliation statement date (or period) being disputed
This seems like boilerplate, but missing or inaccurate identifying information can create procedural questions later. If the lease was assigned and the named tenant is a predecessor entity, use the current tenant name and note the assignment.
2. Lease Reference and Dispute Provision Citation
State explicitly that this letter constitutes formal notice of dispute under a specific lease section. Something like:
"Pursuant to Section 8.3(c) of the Lease Agreement dated March 1, 2019, Tenant hereby provides formal written notice of dispute of the 2024 Annual CAM Reconciliation Statement received on January 15, 2025."
This sentence does several things. It starts your dispute window clock (or demonstrates it is already running). It establishes the correct contractual mechanism. And it signals to the landlord's property management team that this letter needs to go to their legal or accounting department, not into the general correspondence file.
The ABA Real Property section has documented that tenant demands which cite specific lease provisions recover at substantially higher rates than those that do not. The mechanism is simple: a landlord who receives a demand citing Section 8.3(c) has to look up Section 8.3(c) to respond. A landlord who receives a general complaint letter can respond with a general denial.
3. The Overcharge Summary Table
Before the detailed calculations, include a summary table. This lets the reader see the total claim at a glance:
| Line Item | Year | Billed | Should Be | Overcharge |
|---|---|---|---|---|
| Management Fee | 2024 | $27,200 | $17,000 | $10,200 |
| Lobby Renovation (CapEx) | 2024 | $12,500 | $0 | $12,500 |
| Pro-Rata Share Error | 2024 | $8,400 | $7,100 | $1,300 |
| Total | $24,000 |
A table like this accomplishes two things. It shows that your claim is specific and calculated, not estimated. And it gives the landlord's accounting team a clear target for their response, they have to either agree with each line, dispute the lease interpretation, or produce documentation showing different numbers.
4. Line-Item Calculations
For each disputed item in the summary table, include a separate calculation section that shows your work. The minimum for each item:
The lease provision that controls this charge. Quote the relevant sentence, not just the section number. If the management fee cap is "not to exceed four percent (4%) of total operating expenses," quote that language.
What the reconciliation statement shows. The actual line-item amount from the statement you received.
What the correct calculation produces. Using your lease's definitions, show what the charge should have been.
The difference. State the overcharge in dollars.
This is the part of the letter most tenants skip, and it is also the part that decides whether the landlord takes the dispute seriously. A calculation section that traces from lease language to billed amount to correct amount creates a record that is difficult to ignore and, if litigation becomes necessary, is exhibit-ready.
5. Exhibits and Supporting Documentation
Attach whatever you have that supports your calculations:
- Your copy of the reconciliation statement (mark the disputed line items)
- Relevant excerpts from the lease and amendments (the specific sections you are citing)
- Any prior year reconciliation statements that show the same error pattern
- Your payment records for the disputed period
Do not attach everything you have. Attach what is necessary to support the specific claims in your letter. Burying the relevant information in 200 pages of attachments makes your letter harder to process, not more convincing.
6. Documentation Request (Audit Rights Invocation)
Most commercial leases include an audit rights clause that entitles the tenant to inspect the landlord's records supporting the CAM reconciliation. This clause typically requires the tenant to make a written request within a specified period.
Your dispute letter draft should invoke this right explicitly. Cite the section number and request specific records:
- Detailed general ledger showing all operating expenses for the disputed period
- Vendor invoices for amounts above a specified threshold (often $5,000 or $10,000)
- Insurance certificates and premium calculations
- Management fee calculation worksheet showing the base amount and the rate applied
- Pro-rata share calculation showing total rentable area, occupied area, and any exclusions or gross-up adjustments
Some leases specify that the dispute window does not begin until the landlord provides records that are "reasonably detailed." If yours includes that language, note it. It may give you additional time.
7. The Period Under Dispute
State exactly which reconciliation period your letter covers. If you are disputing multiple years, list them. Note the date you received each reconciliation statement (the dispute clock often starts from receipt, not from the date of the statement).
If you are uncertain whether your dispute window is still open, state the dates and note the applicable lease provision. Do not silently assume you are within the window. If there is any ambiguity, address it in the letter.
8. The Specific Resolution Ask
This element is missing from most CAM dispute letters. Tenants frequently state the overcharge amount but fail to state specifically what they want the landlord to do about it.
Be explicit:
"Tenant requests that Landlord issue a credit of $24,000 against Tenant's next quarterly CAM estimate payment, together with written confirmation of the corrected calculation methodology for future reconciliation periods."
Or:
"Tenant requests that Landlord remit $24,000 by check within 45 days, together with a corrected reconciliation statement for the 2024 period."
A specific resolution ask gives the landlord something to say yes to. It also frames any counteroffer against your specific request, which helps keep the negotiation grounded in your numbers rather than the landlord's.
9. Response Deadline
Give a specific date, typically 30 days from the letter's delivery date, and state plainly what happens if you do not receive a response. The options depend on your lease:
- Formal audit request under the audit rights provision
- Mediation or arbitration if the lease requires ADR before litigation
- Filing in the appropriate court or arbitration forum
Keep the tone factual. You are describing a process, not making threats. A statement like "If Tenant does not receive a substantive response by [date], Tenant will proceed with a formal audit pursuant to Section 8.3(d) of the Lease" is appropriate. "If we don't hear from you, we'll sue" is not.
10. Proper Notice Delivery
The letter must be sent by whatever method the lease requires. Read the "Notices" clause and follow it precisely. Common requirements:
- Certified mail with return receipt to a named individual at a specific address
- Overnight courier (FedEx, UPS) with tracking
- Hand delivery with written acknowledgment
Keep all delivery receipts. If the lease permits multiple methods, use the most reliable one, typically overnight courier with tracking. The date of delivery is often what starts or stops the clock on landlord response obligations.

Frequently Asked Questions
What should a CAM dispute letter include?
An effective CAM dispute letter needs: the specific lease provision being violated, the calculation showing what you were billed versus what you owe, a dollar quantification of the overcharge, supporting documentation citations, a clear request for the specific relief you want (credit, refund, or corrected reconciliation), and a response deadline. Without the calculation and lease citation, the letter is too vague to force action.
How specific does the dollar amount need to be in a dispute letter?
As specific as your documentation supports. A letter stating 'the management fee was calculated on $850,000 in expenses rather than the lease-authorized base of $720,000, producing an overcharge of $3,900 at the 3% cap rate' is far more effective than a general claim of overcharging. The landlord needs enough detail to verify or specifically dispute your calculation.
Does a CAM dispute letter need to cite a lease section?
Yes. The letter should cite the specific section of the lease that defines the expense category, pro-rata calculation, or cap provision at issue. A dispute letter that references 'Section 7.2(b) of the Lease' and quotes the relevant language is harder to dismiss than one that makes general claims. Lease citations also establish the paper trail if the dispute escalates.
What documentation should I attach to a CAM dispute letter?
Attach the relevant pages from the lease showing the provision at issue, the landlord's reconciliation statement with the disputed line items highlighted, and your calculation showing the correct figure. If the dispute involves a management fee overcharge, attach the management fee worksheet if the landlord provided one. The letter should be self-contained enough that the recipient can review it without requesting additional documents.
How long should I give the landlord to respond to a CAM dispute letter?
Thirty days is a standard and reasonable response deadline for most commercial CAM disputes. For disputes involving straightforward calculation errors, 15 to 20 days is defensible. For disputes requiring the landlord to commission a review or consult outside counsel, 45 to 60 days may be appropriate. State the deadline explicitly in the letter.
