Dental practices ranging from single-practitioner offices to multi-chair group practices. High water consumption for sterilization and patient care creates outsized utility exposure relative to square footage. Annual CAM exposure for this tenant type ranges up to $8,000-$40,000. CAMAudit runs 14 forensic detection rules specific to your lease structure in under fifteen minutes.
A CAM audit for dental offices examines Modified Gross and NNN lease reconciliations to identify water utility overcharges from aggregate billing without sub-metering, amalgam separator and dental waste costs improperly included in the common area pool, and management fees applied to utility pass-throughs excluded from the fee base.
TL;DR
Dental offices overpay $1,500 to $8,000 per year due to plumbing cost allocation errors and base year gross-up miscalculations.

Annual CAM Exposure
$8,000-$40,000
Modified Gross or NNN, tenant pays a base rent plus utilities and CAM escalations. Water and plumbing costs are frequently passed through directly given the dental practice's above-average consumption.
Dental practices use water for sterilization, patient care, and equipment operation at rates far above typical office tenants. When the building's aggregate water bill is split by square footage rather than usage, the dental tenant may overpay if their actual consumption exceeds their pro-rata share, and neighboring tenants subsidize the dental practice's water use.
EPA 40 CFR Part 441 requires dental practices to operate amalgam separators. This equipment is specific to dental operations and its maintenance cost should not appear in the common area pool. Landlords sometimes include these direct dental costs in general janitorial line items, spreading the cost to non-dental tenants.
Many dental office leases specify that utility expenses are passed through directly and are excluded from the management fee base. When the landlord applies the management fee percentage to the full CAM pool including utilities, the fee is inflated beyond the contractual limit in the lease.
Water utility billed pro-rata without sub-metering
Pro-rata water billing by square footage ignores actual consumption differences among tenants. A dental office with 2,000 SF pays the same rate as a 2,000 SF consulting firm despite consuming several times more water. This either overcharges the dental tenant or forces other tenants to subsidize dental water use.
Detection: Request the building's water invoices and meter configuration. If the building has a single master meter and allocates by square footage, your lease's utility provision determines whether this is contractually valid or a billing error.
Amalgam separator and dental waste disposal in common CAM
Amalgam separator pumping, maintenance, and regulatory reporting are costs specific to dental operations. Including these in the general CAM pool spreads dental-specific regulatory compliance costs to all tenants, which is not a legitimate common area expense.
Detection: Search the reconciliation for 'amalgam', 'dental waste', 'sharps', or 'medical waste' line items. If these appear in the CAM pool rather than as direct charges, dispute their inclusion.
Plumbing repairs for dental-specific infrastructure
Dental-specific plumbing, including chair water lines, sterilization unit connections, and high-volume evacuation system piping, serves only the dental suite. Repairs to these systems should be the tenant's direct cost, not a common area maintenance expense.
Detection: Request plumbing repair invoices and confirm the location and nature of the work. Any repair inside or directly serving the dental suite is a tenant expense, not a CAM charge.
ADA compliance pass-throughs for unrelated building upgrades
ADA compliance upgrades in building common areas are a landlord capital obligation. Dental tenants in multi-tenant medical buildings are frequently targeted for ADA pass-throughs because the medical use creates a perception that accessibility upgrades are tenant-driven.
Detection: Request the building permit for any ADA-related work. Federal law requires building owners to maintain accessible facilities. If the work was required to comply with ADA Title III, it is the landlord's obligation.
Management fee applied to utility pass-throughs
If your lease specifies that utility expenses are passed through outside the management fee base, applying the fee percentage to utilities creates an unauthorized charge. The fee base in the reconciliation should match the contractual definition in the lease.
Detection: Request the management fee calculation worksheet showing the base amount on which the fee was computed. Compare this to your lease's management fee article. If utilities are included in the fee base but excluded by the lease, calculate the overbilled amount.
3-4x
Dental practices consume 3-4 times more water per square foot than standard office tenants, making pro-rata water billing without sub-metering a significant source of overcharges for co-tenants.

Watch For This Trigger
A year-end utility true-up bill arrives showing that the building's aggregate water cost was allocated without sub-metering, resulting in a large unexpected balance.

Court held that water utility allocated without sub-metering violated the lease's direct-measurement provision for variable utility expenses, requiring the landlord to retroactively credit the dental tenant for overpayments attributable to aggregate billing.
