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

  • ✓Pest control is only a legitimate CAM charge for extermination of shared common areas, not individual tenant suites.
  • ✓Food-service tenants attracting pests to their own space must be billed directly for those extermination costs.
  • ✓Request vendor invoices that list the specific areas treated on each service date.
  • ✓Irregular billing frequency relative to the service contract is a reliable indicator of over-billing.
  • ✓Pest costs spiking after a high-risk tenant (restaurant, grocery) moves in warrant immediate investigation.

What Pest Control Covers

Pest control in a commercial CAM context covers routine extermination and prevention services applied to shared common areas: lobbies, corridors, exterior perimeters, mechanical rooms, and parking structures. Under standard lease practice, only the cost of treating common areas belongs in the CAM pool allocated to all tenants. When a specific tenant generates a pest problem, whether a restaurant attracting rodents or a medical tenant requiring specialized pest protocols, the cost of treating that tenant's space must be billed directly to them and excluded from shared CAM. Landlords sometimes bundle all pest control invoices into a single CAM line item, obscuring whether individual suite treatments are being subsidized by unrelated tenants. Industry best practice requires vendor invoices to identify the specific areas treated on each service visit, so tenants can verify that CAM-allocated charges cover only common area scope. CAM reconciliation audits should compare the billed frequency against the contracted schedule and flag any charges for suite-specific extermination.

How Landlords Overcharge on Pest Control

Landlords bill pest control for individual tenant premises - particularly restaurants or food-service tenants who attract pests - through the general CAM pool charged to all tenants.

How to Spot Pest Control Overcharges

  • ⚑Pest control billing frequency inconsistent with any contracted schedule
  • ⚑References to specific tenant suites on pest control invoices
  • ⚑"Emergency extermination" charges for events within a tenant's suite
  • ⚑Pest control costs increase dramatically after a food-service tenant moves in

Legitimate vs. Suspicious Pest Control Charges

Legitimate ChargeSuspicious Charge
✓Quarterly common area extermination billed at contracted rates✗Pest control invoices referencing a specific tenant suite number
✓Monthly exterior perimeter rodent prevention at a market-rate vendor✗Emergency extermination inside a restaurant tenant's kitchen billed to the CAM pool
✓Pest control billing frequency matching the signed service contract✗Six treatments billed in a single month against a quarterly contract
✓Costs consistent with prior years absent a new high-risk tenant✗Pest costs tripling after a food-service tenant opens without a direct-bill adjustment

How to Dispute Pest Control CAM Charges

Limit pest control CAM charges strictly to common area extermination. Individual tenant premises pest control must be billed directly to that tenant. Request vendor invoices specifying the areas serviced on each visit.

From the Founder

“Our tool flagged a reconciliation where every pest control invoice listed a restaurant suite address, yet the full cost was spread pro-rata across all tenants in the building.”
