How to Request CAM Support Documents from a Landlord

How to Request CAM Support Documents from a Landlord

CAM review may find a bill gap. Ask for source files. I built CAMAudit for lease asks.

CAM Support Document Request: A written request from the tenant (or the tenant''s accounting firm) to the landlord asking for underlying documentation that supports specific line items in a CAM reconciliation statement. The request typically references the lease''s audit right provision, identifies the specific reconciliation items in question, and lists the documents needed to verify those items. Common requested documents include vendor invoices, service contracts, allocation methodologies, occupancy data, and landlord workpapers.

When the request is the right next step

Not every finding needs a document request. Many show up from documents the tenant already has. A pro-rata denominator that does not match the lease is one. The denominator is the bottom number that sets the tenant's share. A management fee that includes excluded costs is another. So is a controllable cost rising past the cap. A cap is the ceiling the lease sets. You can raise these with the landlord without more papers.

Ask for documents when:

You cannot verify a line from what the tenant has. The statement shows $48,000 for landscaping. Last year was $32,000. No one explains the jump. The firm asks for the invoices to check it.

The math method is unclear. The management fee says 4% of CAM. But the number does not match any base the firm can find in the statement. The firm asks for the landlord's method and the math behind it.

A special charge has no backup. A code-required upgrade is billed at $22,000 with no invoice and no contractor paper. The firm asks for the backup.

The lease excludes a category that shows up anyway. The statement has a "general administrative" line of $14,000. The lease excludes general administrative from CAM. The firm asks for the breakdown to see what is inside.

In each case, the ask is tied to one item. A broad ask for "all support documentation" looks like a fishing trip. It draws slower replies than a tight, targeted ask.

What documents to ask for

The exact list depends on the findings. Typical requests include:

Vendor invoices for specific expense lines. When you question a category total, the invoices are the source. Ask for invoices for that one category and that one year. Not everything.

Service contracts for recurring charges. A recurring line like security, cleaning, or landscaping may jump. That can hint at a contract change or a markup. The contract shows the basis.

The math method for discretionary pass-throughs. Management fee, gross-up, and allocation methods should be on paper. When the statement does not show the method, the firm asks for the landlord's working math.

Rent roll or occupancy data. When the pro-rata denominator is in doubt, the rent roll proves the real occupied space. It shows the space at year-end and through the year. Occupancy data also matters for gross-up math.

Landlord workpapers. This is the full reconciliation math. It has all categories, all splits, and all method choices in the landlord's own format. It is the biggest ask. Use it when many findings point to a system-wide problem.

List each requested document in the letter. Tie each one to the specific item it supports.

The request letter template

The letter has a set structure. It helps the landlord want to cooperate.

Cite the lease clause. The lease may give the tenant an audit right. It may set steps for backup files. Name the section that allows the request.

Name the specific items. List each line the firm is checking. Add the amount and the year.

List the documents needed. Name each document. Tie each one to the item it supports.

Set a lease-based deadline. Use the audit-rights process and any stated deadline in the lease.

Keep the tone clear and polite. The letter should be open, not hostile. It should show a normal review, not a lawsuit.

A sample opening: "Pursuant to Section [X] of the lease dated [date] between [tenant] and [landlord], we are conducting a review of the [year] CAM reconciliation statement issued [date]. To complete our review, we are requesting the following supporting documentation related to specific reconciliation items..."

Keep the request factual and polite. Follow the lease steps if the reply is late or incomplete.

The single biggest determinant of whether a landlord cooperates with a support document request is the specificity and tone of the request. Broad fishing expeditions invite delay; specific professional requests tied to reconciliation line items get answered. CAMAudit was designed to produce exactly the level of finding-specific documentation the firm needs to make a focused request: this line item, this lease provision, this dollar amount, this question. The structured output translates directly into a structured request letter.

When the landlord delays or refuses

If the landlord does not answer, follow the lease steps. Save all messages.

Step 1: Written follow-up. Send a second letter 5 to 10 business days after the deadline. Point back to the first request. Remind the landlord of the audit-right window. Keep it calm. Do not escalate yet.

Step 2: Use the audit-right steps. If the review time is near its end, say so. Follow the lease steps. Ask counsel to review the clause when needed.

Step 3: Talk to the client. Tell the client the landlord has delayed or refused. The client picks the next step. Wait longer. Use formal audit rights, which may mean an outside auditor or an attorney letter. Dispute the unsupported items on the gap. Or accept them and move on.

Step 4: Take the next formal step. If the client wants to go further, check the signed work. Ask counsel for help when needed. A dispute letter draft needs review. It is not legal advice. Have counsel check it before sending.

Put this path in the signed letter. Then the client knows the firm's work and where expert work starts.

How CAMAudit supports the document request

The tool gives you structured findings. They scope the request for you. For each finding, the tool names the lease clause, the line item, the dollar amount, and the question the documents would answer.

The firm uses this to draft the letter. Each finding becomes one document request. Each is tied to one lease clause and one amount. The landlord sees routine compliance work, not a fishing trip. So more landlords help, and they reply faster.

Some findings the landlord's documents do not resolve. Some the landlord refuses to support. For those, the tool also gives the documented basis for a dispute. The firm has the lease citations and the math ready. That works for an informal note or a formal escalation. See the white-label CAM audit service for audit packs built for firms with different volumes.

Track the request to the end

Track every document request in the firm's working papers. Note the request date. Note the documents asked for. Note the landlord's reply. Note how each finding resolved. Note any follow-up notes. This record protects the firm if the dispute escalates. It also gives the client a clear log of what was asked and what came back.

Run these requests the same way for every commercial real estate client. That habit turns unclear findings into resolved ones. And it gives the client the documented basis for any dispute call they make.

Frequently Asked Questions

When should an accounting firm request CAM support documents from a landlord?

When the reconciliation surfaces a finding that requires verification of underlying expense detail: a management fee calculation that doesn't tie to the categories in the reconciliation, a special assessment without an attached invoice, an operating expense category that's materially higher than prior year, or a category the lease excludes that nonetheless appears in the reconciliation. The request should be specific to the questioned item, not a broad ask for everything.

What documents does the firm typically request?

The typical request list includes invoices supporting specific operating expense line items, contracts or service agreements supporting recurring vendor charges, the calculation methodology for any pass-through with discretionary elements (gross-up, management fee, allocation), the building's rent roll or occupancy data supporting the pro-rata denominator, and any landlord-prepared workpapers showing the reconciliation calculation. The exact list depends on the findings the firm is verifying.

How should the request be written?

Keep the request clear. Point to the lease section that allows review. For example: "Under Section [X], please send [documents]. They support [items] in the [year] CAM bill." Ask for a reply by [date]. Be polite. Follow the lease steps.

What if the landlord delays or refuses?

Read the exact lease clause. Save the date the CAM bill came. If the landlord stalls or says no, save that reply. Let the client or counsel choose what comes next.

How does CAMAudit help with the support document request process?

CAMAudit identifies the specific findings that warrant a support document request, which lets the firm scope the request precisely. Rather than requesting everything (which signals a fishing expedition and slows landlord cooperation), the firm requests support for the specific line items where the platform surfaced findings. The structured detection output also gives the firm documented basis for the request: the lease provision, the reconciliation amount, and the specific question that the support documents are intended to answer.
