The maximum allowable annual increase for controllable operating expenses.
Also known as: Expense Ceiling, Controllable Cap
Without a CAM cap, tenants face unlimited annual increases in operating expense pass-throughs. A 5% annual cap on a $50,000 CAM bill saves the tenant up to $7,500 in year two alone compared to uncapped charges. Over a 10-year lease, the cumulative savings from a well-negotiated CAM cap can exceed $100,000. This is one of the most financially impactful fields to extract accurately.
Found in the "Operating Expenses" or "CAM" section. Look for language like "controllable expenses shall not increase by more than X% per annum." The cap may be stated as a percentage or a fixed dollar amount.
Lextract uses vision AI to read your lease PDF natively (scanned or digital), then multi-pass AI validation identifies and extracts the cam cap %. The AI searches for the field name and common aliases like "Expense Ceiling", "Controllable Cap" across all pages of the document, then assigns a confidence score based on document quality and extraction certainty. Fields with lower confidence are flagged for human review.
Lextract automatically checks this field against its 20-rule red flag engine. Issues detected for cam cap %:
Pro Rata Share

CAM caps typically range from 3% to 5% per year for controllable expenses. A 5% cap is standard in most retail and office markets. Caps below 3% are aggressive and heavily favor the tenant. Some landlords resist any cap, especially in NNN industrial leases.
Non-controllable expenses like real estate taxes, insurance premiums, utilities, and snow removal are commonly excluded from the cap. This means these costs can increase without limit regardless of the cap percentage, which is why identifying the controllable vs. non-controllable distinction is critical.
No. A CAM cap only limits increases in controllable operating expenses. Taxes, insurance, and utilities typically increase without limit. Additionally, a cumulative (compounding) cap is less protective than a non-cumulative (resetting) cap over time.
