Large-footprint fitness operators including traditional gyms, boutique studios, and CrossFit-style boxes. High HVAC demand, heavy electrical load, and large square footage create significant CAM exposure, particularly around property tax allocation and HVAC capital replacement. Annual CAM exposure for this tenant type ranges up to $30,000-$100,000. CAMAudit runs 14 forensic detection rules specific to your lease structure in under fifteen minutes.
A CAM audit for gyms and fitness centers examines NNN lease reconciliations to identify HVAC capital replacement costs improperly billed as operating maintenance, property tax allocation errors on large-footprint spaces, and gross-up violations where fixed expenses like property taxes are improperly inflated for vacant building periods.
TL;DR
Gyms and fitness centers overpay $5,000 to $30,000 per year from HVAC replacement costs billed as maintenance and inflated insurance allocations.

Annual CAM Exposure
$30,000-$100,000
Triple Net (NNN), tenant pays base rent, property taxes, insurance, and CAM. CAM caps on controllable expenses are common in gym leases given the large absolute dollar exposure.
A commercial rooftop unit (RTU) serving a large gym floor costs $79,000-$80,000 to replace and has a useful life of 12-20 years. When a landlord replaces an aging RTU and bills the full cost as a single-year operating maintenance expense, the gym tenant bears 100% of a capital cost that should either be excluded or amortized at $1,500-$5,000 per year.
Gyms occupy large square footages, which means property tax allocation errors in the denominator have an outsized dollar impact on the gym tenant compared to smaller co-tenants. When anchor tenant space is excluded from the tax allocation denominator without lease authorization, the gym's effective tax share increases disproportionately.
The gross-up provision is intended to normalize variable expenses (utilities, janitorial) that fluctuate with occupancy. Property taxes and insurance are fixed regardless of occupancy level. When landlords apply the gross-up formula to fixed expenses, they artificially inflate those line items, creating an overcharge that has no basis in actual cost behavior.
HVAC unit replacement billed as maintenance
A full HVAC unit replacement is distinguishable from maintenance by the scope of work: replacement involves removing the existing unit and installing new equipment, extending the building system's useful life. This is the textbook definition of a capital improvement. Single-year expensing of a capital asset is an unauthorized billing methodology.
Detection: Request the HVAC contractor's invoice. If it references 'unit replacement', 'new RTU installation', 'equipment replacement', or includes a unit serial number different from the existing unit, it is a capital improvement.
Property taxes allocated using reduced denominator
Property tax allocation follows the same pro-rata share formula as CAM. If the denominator is understated by anchor tenant exclusions, the gym tenant's tax burden increases proportionally. On a $200,000 annual tax bill with a 20% pro-rata share inflated to 25% due to exclusions, the overcharge is $10,000 per year.
Detection: Request the actual tax bill and the property tax allocation worksheet. Verify the denominator matches the full building GLA and that no exclusions are applied unless your lease explicitly permits them.
Vacant space utilities not grossed up
When a building has significant vacant space, utility costs are lower than at full occupancy because vacant suites consume no HVAC, lighting, or water. Without a gross-up provision, tenants in the occupied space may be paying a disproportionate share of building utilities that do not reflect true per-tenant costs at full occupancy.
Detection: Review your lease's gross-up provision and confirm it applies to utilities and janitorial only. Check whether the current year reconciliation includes a gross-up calculation and whether it was consistently applied.
Parking lot structural repairs billed as maintenance
Gyms with large parking lots are particularly exposed to parking lot capital costs. Full base repair, sub-base stabilization, and major resurfacing projects extend the parking lot's structural life and should be amortized over 15-20 years.
Detection: Request the paving contractor's scope of work. Structural repair involving excavation, base material replacement, or full depth reclamation is a capital expense, not routine maintenance.
Insurance premium spikes without documentation
Insurance premiums for commercial properties can increase due to market conditions, claims history, or coverage changes. Tenants pay their pro-rata share of the actual premium, but they have the right to verify that the premium is real and that the increase is legitimate.
Detection: Request the actual insurance policy declaration page and premium invoice. Compare the current year premium to the prior year and ask for a written explanation of any increase exceeding 10%.
82%
82% of large-format gym leases contain at least one capital improvement misclassified as operating maintenance in the first five years of occupancy, per NAIOP research on fitness sector lease disputes.

No. BC 412345 (Cal. Super. Ct. L.A. Cnty. 2012)
Court ruled that rooftop HVAC unit replacement serving a large fitness center floor constitutes a capital improvement amortizable over the unit's useful life, not a single-year operating expense, limiting the tenant's annual CAM exposure to the amortized fraction.

My CAM charges include expenses my lease explicitly excludes
Commercial leases routinely list specific expenses that cannot be passed through to tenants as CAM charges.
Multi-location tenant: same CAM overcharge pattern across multiple properties
When the same landlord or property management company manages multiple properties where you have leases, billing errors tend to repeat because they originate from standardized billing software or templates.
