CAM Expense Caps Explained — How Tenants Limit Annual Increases

What Is a CAM Expense Cap?

A CAM expense cap limits how much a landlord can increase common area maintenance charges from year to year. These caps are designed to protect tenants from unpredictable or excessive cost increases.

CAM caps typically apply to operating expenses only and often exclude real estate taxes and insurance.

Typical CAM Expense Cap Ranges

• 3% annually (very common)
• 5% annually
• CPI-based caps (inflation-linked)
• Fixed dollar caps (rare but powerful)

Even small cap violations compound quickly. A 2–3% overage can turn into tens of thousands of dollars over a multi-year lease.

How CAM Expense Caps Are Commonly Violated

• Applying the cap to the wrong base year
• Resetting the cap after reconciliation
• Including excluded expenses to bypass the cap
• Applying the cap to a subtotal instead of total CAM
• Misclassifying capital expenses as operating costs

These violations are rarely obvious unless the lease is reviewed alongside the reconciliation statement.

Why Most Tenants Miss CAM Cap Violations

• CAM statements lack transparency
• Caps are buried deep in lease language
• Annual increases feel “normal”
• Audit windows quietly expire

By the time tenants realize something is wrong, their right to challenge the charges may already be limited.

What Tenants Can Challenge

• CAM increases above the lease cap
• Incorrect base year calculations
• Improperly classified expenses
• Unsupported reconciliation numbers

Challenging these issues often leads to refunds, credits, or corrected future charges.
