Legal practices occupying premium Class A office space in downtown and suburban markets. Full-Service Gross leases with Base Year stops are standard. Law firms are sophisticated tenants but often rely on office managers rather than lease experts for CAM oversight, creating exposure to base year errors. Annual CAM exposure for this tenant type ranges up to $30,000-$80,000. CAMAudit runs 14 forensic detection rules specific to your lease structure in under fifteen minutes.
A CAM audit for law firms examines Full-Service Gross lease reconciliations to identify base year gross-up failures that inflate operating expense escalations throughout the lease term, property tax post-sale reassessment overcharges, and administrative fees included in the operating expense pool without lease authorization.
TL;DR
Law firms in full-service gross leases overpay $2,000 to $12,000 per year from base year gross-up errors and controllable expense cap violations.

Annual CAM Exposure
$30,000-$80,000
Full-Service Gross with Base Year Stop, landlord pays all operating expenses up to the base year amount; tenant pays the proportionate share of increases above that amount. Base year is typically the first year of occupancy.
If a law firm's lease commenced during a period of low building occupancy, say 70%, the actual base year operating expenses were lower than they would be at 95% occupancy. Without grossing up the base year, the landlord establishes a falsely low baseline. Every subsequent year, the escalation is measured against this deflated floor, producing inflated charges for the entire 5-10 year lease term.
Applying the gross-up formula to current year expenses but not to the base year creates an asymmetric comparison that systematically overstates the escalation. Courts have uniformly held that gross-up must be applied consistently; failing to do so is a breach of the lease that entitles the tenant to recover overpayments for every year affected.
When a Class A office building is sold, the property is reassessed at the transaction price, which may be significantly above the prior assessed value. The resulting property tax increase flows into the operating expense pool. Some leases cap ownership-transfer reassessments; without a cap, the full increase passes through and compounds annually.
Base year not grossed up to 95% occupancy
Most Full-Service Gross leases contain a provision requiring the base year operating expenses to be grossed up to 95% building occupancy to reflect normalized costs. When the landlord uses actual base year expenses from a low-occupancy period, the base year understates true operating costs, and every subsequent escalation is overstated by the same proportion.
Detection: Review the base year operating expense exhibit in your lease. Confirm it includes a gross-up adjustment. If the building was not 95% occupied in the base year and no gross-up adjustment is shown, calculate the gross-up impact: (actual expenses) / (actual occupancy %) x 95% = grossed-up base. The difference is your annual overcharge.
Janitorial grossed up in current year but not base year
Even when gross-up is applied correctly overall, landlords sometimes apply it inconsistently to specific line items. Grossing up janitorial in the current year reconciliation while using actual (un-grossed) janitorial costs in the base year creates an artificial delta that inflates the janitorial escalation.
Detection: Compare the base year janitorial cost to the current year gross-up-adjusted janitorial cost. If gross-up was applied to current year janitorial, verify that the same adjustment appears in the base year exhibit.
Security costs reclassified from capital to operating
When a building upgrades its security system, including camera systems, access control, and monitoring infrastructure, these are capital improvements. Reclassifying them as operating expenses mid-lease allows the landlord to include them in the operating expense pool and pass the cost to tenants as a recurring expense.
Detection: Request the security system vendor's invoice. If the work involved new equipment installation or system replacement, it is a capital improvement not eligible for inclusion in the operating expense pool.
Property tax post-sale reassessment in full
Ownership-transfer reassessments can double or triple annual property taxes on high-value office buildings. If the lease contains no tax cap or phase-in provision, the full increase is a legitimate pass-through. However, tenants should verify the actual tax bill and confirm the increase is correctly stated in the reconciliation.
Detection: Request the actual tax bill from the county assessor (often publicly searchable by parcel number). Compare the billed tax to the reconciliation amount. Verify no penalties are included.
Administrative fees without lease authority
Administrative fees, portfolio management fees, and above-grade management company overhead are not legitimate operating expenses under most Full-Service Gross leases. These costs must be explicitly authorized in the lease's operating expense definition.
Detection: Search the reconciliation for line items labeled 'administrative fee', 'portfolio management', 'asset management', or 'accounting fee'. If these terms appear, cross-reference with your lease's operating expense definition to confirm they are authorized.
72%
72% of Class A office leases signed during below-average building occupancy periods contain base year gross-up errors that inflate operating expense escalations for all subsequent years.

New York Court of Appeals established that operating expense gross-up provisions must be applied consistently to both the base year and current year operating expenses. Grossing up current year expenses but not the base year creates an artificial escalation that constitutes a breach of the lease.
