Veterinary clinic lease: hidden costs your landlord didn't disclose
Opening a veterinary clinic requires a substantial build-out. Treatment rooms, surgical suites, recovery wards, boarding kennels, isolation rooms, and specialized ventilation systems represent hundreds of thousands of dollars in tenant improvements. If you negotiated a tenant improvement allowance from your landlord to cover part of that build-out, the landlord got something in exchange: a lease structured to recover that investment over time.
Here's what most practice owners don't know: some landlords recover their investment through the CAM pool, not just through the rent schedule. Build-out improvements that the landlord funded may reappear in the operating expense pool as ongoing maintenance obligations. Infrastructure that your practice needs but that isn't standard to the building may get allocated into the shared expense pool.
The result is that your annual CAM bill includes costs that weren't disclosed upfront and that may not belong there under your lease terms.
Veterinary tenant improvements: Customized build-out work performed to prepare a commercial space for veterinary clinic operations. Typical improvements include specialized ventilation for anesthetic gas scavenging, reinforced flooring, plumbing for multiple exam rooms, isolation ward construction, and boarding facility infrastructure. The cost allocation between landlord-funded and tenant-funded improvements affects ongoing CAM obligations.
The ventilation issue in veterinary CAM
Veterinary clinics require specialized exhaust ventilation for several reasons:
Anesthetic gas scavenging. Procedures using inhalant anesthetics such as isoflurane require scavenging systems to capture waste anesthetic gas and prevent exposure to clinic staff. These systems require dedicated exhaust pathways that are separate from standard HVAC.
Boarding facility odor and pathogen control. Kennels and boarding areas require higher air exchange rates and specialized exhaust to manage odors and reduce pathogen transmission between animals. The infrastructure supporting this is more substantial than standard commercial HVAC.
Surgical suite ventilation. Sterile procedure areas require positive pressure relative to surrounding spaces and specialized filtration.
In a NNN lease, the question is whether the building's HVAC and ventilation system serving your clinic is a shared system (CAM-eligible) or a dedicated system (tenant responsibility). If your lease treats the exhaust ventilation serving your clinic's surgical suite and boarding area as a shared building system rather than a dedicated tenant-exclusive system, its maintenance and service costs flow into the CAM pool and are allocated across all building tenants.
If that sounds like a favorable arrangement for your practice, it may be. But it also creates a situation where non-veterinary tenants in your building are subsidizing your specialized systems, which is not always what the building owner intends or what the lease supports when read carefully.
More on that below: the distinction matters because when these costs appear in CAM, they often get allocated by square footage regardless of who actually uses the systems.
Biohazard and medical waste in veterinary CAM
Veterinary practices generate regulated medical waste: contaminated sharps, biological samples, pathological waste, and pharmaceutical waste. Disposal of this waste is regulated and carries specific costs.
Some commercial buildings, particularly veterinary-specific or mixed medical-use buildings, include centralized biohazard waste handling infrastructure in the CAM pool. Others treat it as a tenant responsibility.
The risk for veterinary tenants appears when:
- The building has centralized sharps disposal or biohazard holding rooms
- These costs appear in the CAM pool
- The allocation method does not reflect actual generation by tenant type
A billing and administrative office in the same building as your veterinary clinic generates essentially zero regulated waste. If they pay the same pro-rata share of biohazard disposal infrastructure costs that your clinic pays, the allocation is arguably inequitable, though whether it's a lease violation depends entirely on your specific lease language.
Build-out costs that resurface in CAM
This is where things get genuinely complicated for veterinary tenants.
When a landlord funds a substantial build-out, they sometimes structure the lease so that maintenance obligations for those improvements flow back to the tenant through CAM. Specifically:
Specialized equipment maintenance. If the landlord's build-out included specialized exhaust fans, isolation room pressure systems, or custom plumbing fixtures and those systems are treated as building infrastructure rather than tenant-owned fixtures, their maintenance costs may appear in CAM.
Custom flooring. Veterinary clinics use commercial-grade, easy-to-clean flooring in treatment and ward areas. If the landlord installed this flooring as part of the tenant improvement package and the lease treats it as a building improvement rather than tenant-owned property, replacement and maintenance may flow through CAM.
Sound mitigation infrastructure. Boarding facilities are noisy. Some landlords install sound attenuation measures as part of the build-out to protect other tenants in the building or neighboring spaces. If this infrastructure is treated as a building improvement, its maintenance costs can flow into CAM.
The key is to review your lease's definition of tenant improvements versus landlord improvements, and whether maintenance of those improvements is a tenant obligation or a building operating expense. If it's a building operating expense, confirm whether your lease includes or excludes it from CAM.
"Veterinary practice owners spend years building specialized clinic spaces. After all that investment, the last thing they expect is to pay for that infrastructure again through CAM. But it happens when the lease doesn't clearly define what goes in the operating expense pool." — Angel Campa, Founder of CAMAudit
Strip mall and standalone veterinary clinic CAM
Many veterinary clinics occupy strip mall endcaps, standalone buildings, or freestanding structures in mixed-use developments. In these settings, the CAM dynamics differ from MOB settings.
Strip mall endcap. You are an inline or endcap tenant sharing parking, landscaping, exterior lighting, and exterior building maintenance costs. The pro-rata share error risks are standard: management fee violations, denominator issues, capital versus operating classification. The specific veterinary risk is any line item related to odor control, pest management, or structural maintenance that the landlord attributes to your high-traffic space specifically but bills to the entire pool.
Standalone building with ground lease or NNN. If you occupy a standalone building on a NNN lease, you may have direct responsibility for building maintenance rather than a pooled CAM arrangement. In this structure, the hidden cost risk shifts to capital obligations: who pays for roof replacement, HVAC system replacement, and major structural repairs. Confirm your lease's capital improvement provisions carefully.
What to audit in a veterinary clinic lease
The review checklist for a veterinary practice:
Management fee: Find the fee cap in your lease and compare to the reconciliation. Add up all fee-related line items before comparing.
Pro-rata denominator: Request a rent roll and verify the total rentable square footage used to calculate your share.
Specialized building systems: Identify any line items related to ventilation, HVAC, exhaust, or specialized mechanical systems. Determine whether these are shared systems or systems that exclusively serve your space.
Waste-related costs: Any biohazard, medical waste, or specialized disposal line items. Verify inclusion or exclusion under your lease.
Capital items: Large repair or replacement line items for roofing, parking, HVAC, or structural elements. Confirm whether amortization is required.
Build-out maintenance: Any maintenance costs that may relate to improvements installed during your clinic's build-out.

Questions veterinary practice owners ask about CAM
Frequently Asked Questions
Is specialized ventilation for my surgical suite a CAM expense or my own responsibility?
It depends on your lease. If the ventilation system is a dedicated system serving only your space, it is typically your maintenance responsibility. If it is part of the building's central exhaust infrastructure, it may be a CAM expense. Review your lease's definitions of building systems versus tenant-exclusive systems.
Can my landlord charge the entire building for biohazard waste disposal that only my clinic generates?
If the lease includes building-wide waste handling in the CAM definition, the landlord can pool this cost across all tenants. Whether that is appropriate depends on your specific lease language, not on what seems equitable.
What happens to the TI allowance my landlord gave me if I audit their CAM charges?
The tenant improvement allowance is a separate transaction from the CAM audit. Your right to audit operating expenses exists independently of the landlord's build-out contribution. Auditing the reconciliation does not affect the TI allowance terms.
My landlord increased CAM significantly after I installed boarding kennels. Is that fair?
The question is whether the lease supports the increase. If your boarding operation added demand to shared building systems and the lease includes those system costs in CAM, some increase may be appropriate. But the method of calculation and allocation still needs to match your lease terms.
How long do I have to contest a CAM charge for a prior year?
Most commercial leases provide 12-24 months from receipt of the annual reconciliation to contest charges. Check your audit rights clause for the specific window applicable to your lease.
