Medical Practice Lease Overcharges: Where Healthcare Tenants Lose Thousands
Medical office tenants frequently face layered and compounding CAM and NNN overcharges. Specialized infrastructure, capital upgrades, and percentage-based administrative fees create exposure that many practices never detect until it is too late.
In outpatient medical office buildings, lease overcharges frequently stem from triple net (NNN) structures, percentage-based administrative fees, insurance repricing cycles, and capital improvement allocation language. Without structured CAM reconciliation review, healthcare tenants may absorb expenses that exceed lease-defined caps or permissible amortization provisions.
What Overcharges Actually Cost Medical Tenants
10,000 SF practice × $2 PSF improper charge = $20,000/year
10,000 SF practice × $4 PSF error = $40,000/year
Over a 5-year term, that can exceed $200,000 in preventable exposure.
These overcharges often hide inside reconciliation statements that appear routine and technical.

Many medical leases cap CAM admin fees at 8–12%. Overcharges occur when management fees are layered separately, when caps are applied to expanded expense categories, or when percentage calculations are performed incorrectly.
2. Double-Charged Maintenance Contracts
Elevator servicing, HVAC maintenance, generator testing, and parking structure upkeep may appear both in master building contracts and as individual CAM line items — resulting in duplicate billing.
3. Capital Expenses Disguised as Operating Costs
Roof replacements, structural repairs, and major system upgrades are sometimes amortized through CAM despite lease exclusions. Medical properties frequently see this following compliance-driven improvements.
Real Example: Imaging Tenant Admin Fee Violation
A 12,000 SF imaging center had CAM admin fees capped at 10%. The landlord applied 18% for three consecutive years.
Annual overcharge: approximately $28,800.
Three-year exposure: over $86,000.
4. Management Fees Exceeding Allowed Percentages
Some leases restrict management compensation to a defined percentage of operating expenses. When operating expenses spike, improper percentage calculations can materially increase tenant exposure.
Why Medical Practices Are Especially Vulnerable
- High infrastructure requirements (HVAC, electrical, backup power)
- Regulatory-driven capital upgrades
- Complex pro-rata share allocations in MOBs
- Limited internal lease audit expertise
- Short audit windows buried in lease language
Why Timing Matters: Audit Windows Close Quickly
Most medical office leases allow only 6–12 months after reconciliation delivery to formally dispute CAM and NNN overcharges. Missing this deadline can permanently waive recovery rights for that year.
