Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

Key Takeaways

  • ✓Guard wages, monitoring fees, and routine system maintenance are operating expenses; hardware installations are capital
  • ✓A new camera or access control system must be amortized over its useful life, not expensed in a single CAM year
  • ✓A 50% or greater year-over-year spike in security costs warrants a full documentation request before payment
  • ✓Security upgrades installed after a building sale are often timed to boost NOI before a new owner stabilizes the asset
  • ✓Request a line-by-line breakdown separating service fees from equipment and installation costs

What Security & Guard Services Covers

Security and guard services in commercial leases cover the recurring costs of protecting common areas and the building perimeter: guard wages and staffing agency fees, 24/7 monitoring contracts, routine camera system maintenance, and access control software licenses. These are legitimate operating expenses recoverable from tenants in a standard NNN or modified gross lease. The capital abuse pattern emerges when landlords install a new security infrastructure and pass the full cost through in a single reconciliation year. A complete camera system, access control hardware, intercom installation, or security booth construction is a capital expenditure because the equipment has a useful life extending beyond one year. That cost must be amortized over the equipment's useful life, typically 7-10 years, and only the annual amortized share belongs in the CAM pool. Tenants should scrutinize large one-time security charges appearing in the same year as a building sale or major renovation, as these are common timing patterns for improper capital expensing. A request for vendor contracts distinguishing hardware purchase components from service agreements is the first step in any security cost dispute.

How Landlords Overcharge on Security & Guard Services

Installation of a new $100,000 camera and access control system is passed through as "security services" in a single year rather than amortized as a capital system improvement.

How to Spot Security & Guard Services Overcharges

  • ⚑A sudden 50% or greater spike in security costs without explanation
  • ⚑"Camera installation," "access control system," or "security system upgrade" on invoices
  • ⚑Security costs after a building sale when the buyer upgrades the system
  • ⚑New monitoring contracts with hardware purchase components bundled in

CapEx Risk Alert

This line item is commonly used to disguise capital expenditures as operating expenses. Capital expenditures must be excluded from CAM or amortized over their useful life per GAAP. If you see unusually high or one-time charges in this category, request all invoices and scope-of-work documentation before paying.

Legitimate vs. Suspicious Security & Guard Services Charges

Legitimate ChargeSuspicious Charge
✓Monthly guard staffing fees from a licensed security firm at contract rates✗"Security system installation" or "camera infrastructure upgrade" billed as a single-year operating expense
✓Annual monitoring contract for existing camera and access control systems✗New monitoring contract with hardware purchase components bundled into the monthly fee
✓Routine maintenance and software updates for an existing security system✗Full access control system replacement billed as maintenance in the year of a building sale
✓Security cost increases consistent with a documented contract rate adjustment✗A 60%+ cost spike with no explanation and no prior documentation of the need for new infrastructure

How to Dispute Security & Guard Services CAM Charges

Separate recurring security service fees (guards, monitoring) from capital security system installations. Hardware and system installations must be amortized or excluded. Request vendor contracts to verify what is a service fee versus an equipment purchase.

From the Founder

“I built CAMAudit because security system upgrades after a building sale are one of the cleanest examples of a landlord using tenant CAM dollars to fund a capital improvement that benefits the new owner, not the tenants.”
