Commercial Lease Audit for Tenants
A commercial lease audit for tenants reviews your lease language and annual CAM / NNN charges to determine whether costs were billed correctly — and whether avoidable overcharges exist.
For many small and mid-sized commercial tenants, lease audit reviews uncover $5,000–$50,000+ in annual exposure tied to administrative fees, allocation errors, and improperly passed-through expenses.
What Is a Commercial Lease Audit?
A commercial lease audit compares:
- The lease’s defined CAM / NNN language
- Expense caps and exclusions
- Pro-rata allocation methodology
- Annual CAM reconciliation statements
- Administrative and management fees
The goal is simple: confirm whether the charges match what the lease actually allows.
Why Commercial Tenants Often Need a Lease Audit
Commercial leases are complex. CAM (Common Area Maintenance) and NNN (triple net) structures frequently include:
- Broad expense definitions
- Vague capital expenditure language
- Management fee markups
- Allocation changes over time
- Limited audit windows (30–90 days)
Without reviewing the lease language against the reconciliation statement, overcharges can compound year after year.
Common Findings in Commercial Lease Audits
Administrative Fees Above Lease Caps – Many leases cap admin fees at 10–15%, yet higher percentages are sometimes applied.
Improper Capital Improvements – Structural or long-term upgrades passed through as operating expenses.
Allocation Errors – Incorrect square footage or pro-rata share calculations.
Duplicate Charges – Expenses appearing in both CAM and NNN categories.
Why Timing Matters
Most leases include a limited audit window — often 30 to 90 days after receiving the reconciliation statement.
If that window closes, leverage decreases. Reviewing your lease before the deadline preserves your ability to dispute improper charges.
