Enforceability of Lease Clauses Requiring Tenants to Pay for Security Upgrades

Lease clauses requiring tenants to pay for common area security upgrades are generally enforceable if the language is explicitly included in the Common Area Maintenance (CAM) or 'Operating Expenses' section of the lease. Courts prioritize the 'four corners' of the contract, meaning if the lease defines security upgrades as a recoverable expense, the tenant is legally obligated to pay their pro-rata share.

The Legal Framework of CAM Charges

In commercial real estate, the enforceability of security-related charges hinges on how the lease defines 'Operating Expenses.' Landlords often attempt to pass through the costs of new surveillance systems, security personnel, or access control hardware to tenants. Whether these are recoverable depends on the specific classification of the expense.

Operating Expenses vs. Capital Expenditures

The primary point of contention is whether a security upgrade is a recurring maintenance cost or a capital improvement. Most standard leases allow for the pass-through of operating expenses but restrict or amortize capital expenditures.

Expense TypeTypical TreatmentTenant Risk
Security PersonnelOperating Expense (Fully Recoverable)Low
Surveillance MaintenanceOperating Expense (Fully Recoverable)Low
New Camera SystemsCapital Expenditure (Amortized)Moderate
Structural Security UpgradesCapital Expenditure (Often Excluded)High

Key takeaway: Always verify if your lease allows the landlord to recover 'capital improvements' under the CAM definition. If it does, ensure there is an amortization clause that spreads the cost over the useful life of the equipment rather than charging it as a lump sum.

Action Item: Review your lease's 'Exclusions from Operating Expenses' section. If 'capital improvements' are not listed as an exclusion, you are likely liable for security upgrades.

Criteria for Enforceability

For a landlord to successfully enforce a charge for security upgrades, the following criteria must be met:

  • Specificity: The lease must explicitly mention security or safety systems as a recoverable expense.
  • Reasonableness: The upgrade must be deemed necessary for the operation of the building, not merely an aesthetic or speculative improvement.
  • Pro-rata Allocation: The cost must be distributed fairly among tenants based on their square footage or a pre-agreed percentage.
  • Compliance with Law: If the upgrade is mandated by local municipal code (e.g., fire safety or ADA compliance), it is almost always enforceable.

Red Flags in Security Clauses

Tenants should be wary of 'catch-all' language that grants landlords broad discretion. Watch for these specific phrases in your contract:

  • 'Any and all costs related to building safety' (Too broad).
  • 'Costs incurred at Landlord’s sole discretion' (Removes tenant oversight).
  • 'Non-recurring capital expenditures' (Often used to hide expensive, one-time security overhauls).

Action Item: If you find these phrases, draft an addendum that limits security-related capital expenditures to items required by law or those that provide a direct, measurable reduction in insurance premiums.

Strategies for Mitigation

If you are currently negotiating a lease or auditing an existing one, use these strategies to limit your financial exposure:

  1. Negotiate a Cap: Request a 'controllable expense cap' that limits annual increases in CAM charges to a specific percentage (e.g., 3-5% annually).
  2. Audit Rights: Ensure your lease grants you the right to inspect the landlord’s books and records regarding CAM charges within 60 to 90 days of receiving the annual statement.
  3. Amortization Requirements: Require that any security upgrade costing more than $5,000 be amortized over its useful life (typically 5-10 years) rather than charged in a single year.

Key takeaway: Never accept a lease that allows the landlord to pass through 'all costs of ownership.' Always insist on a clear, itemized definition of what constitutes a recoverable security expense.

Action Item: Request a breakdown of the last three years of CAM charges from your landlord to identify if security upgrades have been historically inflated or misclassified.
