An illustrative example
A CAM total is built from smaller pieces.
Suppose an annual statement shows landscaping, cleaning, and an administration fee. You can test the fee base separately from the underlying services and compare the tenant share against the area schedule.
Illustrative structure. The signed lease controls which costs and fees may be charged.

What the documents can tell you.
Are CAM charges automatically extra rent?
A lease may classify or bill them in different ways. Read the agreement's payment and default provisions.
Does a positive true-up mean an overcharge?
No. It means annual charges exceed estimates credited on that statement. The inputs still need review.
Does a flagged item prove an overcharge?
No. It is a question to verify against the signed lease, the annual statement, and supporting records. A charge can be valid even when it warrants review.
Is there a standard audit deadline?
No. Read the signed lease and amendments for the trigger, period, required action, recipient, and delivery method. Different review steps may have different rules.
