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.

Rent Abatement Clause

Last updated: April 2026

By Angel Campa, Founder

An estimated 50-60% of rent abatement clauses exclude CAM charges, meaning you may pay full operating expenses even when you cannot use the space.

What Is a Rent Abatement Clause?

A rent abatement clause provides for reduction or elimination of rent (and sometimes CAM payments) during specific circumstances, such as the initial lease-up period, property damage, landlord default, or significant disruption to the tenant's use of the premises. The abatement may be automatic upon a triggering event or require formal notice.

Why This Clause Matters for CAM Audits

Rent abatement provisions that include CAM can provide meaningful financial relief when circumstances prevent the tenant from fully using the premises. However, many abatement clauses apply only to base rent, leaving CAM obligations in full force even when the tenant cannot occupy the space. This creates a situation where you pay for maintenance of areas you cannot use.

Sample Lease Language

“If, as a result of a casualty, condemnation, or Landlord's failure to maintain the Building in a manner that substantially impairs Tenant's use of the Premises for more than five (5) consecutive business days, Tenant's Rent (including Tenant's share of Operating Expenses) shall abate in proportion to the square footage rendered unusable until the condition is remedied. For the avoidance of doubt, "Rent" as used in this Section includes Minimum Rent, Additional Rent, and Tenant's share of Operating Expenses. Abatement shall commence automatically upon the qualifying event without the need for notice.”

This is illustrative language only. Your actual lease language controls your rights.

Red Flags to Watch

  • ⚠Abatement applies only to base rent, not CAM or operating expense payments
  • ⚠Triggering conditions are extremely narrow (only total destruction, not partial impairment)
  • ⚠Tenant must provide written notice and wait for a cure period before abatement begins
  • ⚠Landlord can terminate the lease instead of providing abatement
  • ⚠No abatement for landlord-caused disruptions or maintenance failures

Negotiation Tips

  • ✓Define "Rent" to include base rent, additional rent, and operating expense payments for abatement purposes
  • ✓Include a range of triggering events: casualty, condemnation, landlord default, and maintenance failures
  • ✓Negotiate automatic abatement without a notice requirement for events exceeding a short threshold
  • ✓Ensure partial impairment (not just total inaccessibility) triggers proportional abatement
