1. MOB vs. General Office: Choosing the Right Property Type
The first and most fundamental decision for any healthcare tenant is whether to lease in a purpose-built Medical Office Building (MOB) or in a general commercial building. This decision drives every infrastructure and lease consideration that follows.
| Feature | Medical Office Building (MOB) | General Office Building |
|---|---|---|
| HVAC | Dedicated zones, enhanced ACH, independent controls per suite | Shared system, limited after-hours control, insufficient ACH for clinical use |
| Plumbing | Multiple sinks per floor, floor drains, medical gas rough-ins available | Standard sink count, medical gas requires expensive new rough-in |
| Electrical | Higher capacity panels, isolated ground circuits, generator backup common | Standard office capacity; imaging equipment may require new service |
| Parking | 5–6 per 1,000 SF (handicapped-accessible, close to entrance) | 3–4 per 1,000 SF (may be insufficient for patient volume) |
| Floor Load Capacity | 80–125 lbs/SF (supports imaging equipment) | 50–80 lbs/SF (may require reinforcement for heavy equipment) |
| Co-location Benefits | Often adjacent to hospitals or specialty practices (referral network) | None |
| Rent Premium | $5–$15/RSF higher than comparable general office | Lower base rent |
| Build-Out Cost | Lower — infrastructure already in place | Higher — must install medical-grade infrastructure from scratch |
The premium rent in an MOB is frequently offset by lower build-out costs. A medical practice spending $200/SF to convert a general office building's cold shell can spend $100–$130/SF in an MOB that already has medical infrastructure in place.
Total Cost Comparison: MOB vs. General Office (3,000 SF Practice)
General Office: $28/RSF base rent + $140/SF build-out
→ Year 1 rent: $28 × 3,000 = $84,000
→ Build-out: $140 × 3,000 = $420,000
→ TI allowance: $60/RSF = $180,000 → Net build-out out-of-pocket: $240,000
→ 5-year total: ($84,000 × 5) + $240,000 = $660,000
MOB: $38/RSF base rent + $85/SF build-out
→ Year 1 rent: $38 × 3,000 = $114,000
→ Build-out: $85 × 3,000 = $255,000
→ TI allowance: $80/RSF = $240,000 → Net build-out out-of-pocket: $15,000
→ 5-year total: ($114,000 × 5) + $15,000 = $585,000
→ MOB is $75,000 less expensive over 5 years despite higher rent
2. HIPAA and Privacy Considerations in the Medical Office Lease
The Health Insurance Portability and Accountability Act (HIPAA) imposes requirements for protecting Protected Health Information (PHI) that directly affect the physical design of medical office spaces and, by extension, their leases. While HIPAA compliance is ultimately the tenant's responsibility, the lease must not create conditions that make compliance impossible.
Soundproofing and PHI Privacy
HIPAA's Privacy Rule requires "reasonable safeguards" to protect verbal PHI from incidental disclosure. In a medical office, this means walls between exam rooms and waiting areas, and between clinical areas and any shared spaces, must provide adequate sound attenuation.
- Standard commercial drywall (single layer) typically provides STC (Sound Transmission Class) ratings of 30–35 — barely adequate for general office use but insufficient for clinical settings
- Medical office exam rooms should target STC 45–50, achievable with double-layer drywall, resilient channels, or acoustic insulation in wall cavities
- The lease and work letter should specify acoustic performance standards for exam room and consultation room walls
Landlord Access and HIPAA Compliance
Most commercial leases allow landlords broad rights to enter the premises for inspections, maintenance, and emergency access. For medical tenants, unrestricted landlord access creates HIPAA exposure. Negotiate:
- Enhanced notice requirements for non-emergency landlord entry (48–72 hours vs. standard 24 hours)
- Requirement that landlord maintenance staff be accompanied by practice staff when entering any area where patient records are stored or accessible
- Landlord acknowledgment that they are aware of HIPAA obligations and will cooperate with tenant's access control protocols
- Specific restrictions on landlord camera/surveillance access to clinical areas
⚠️ Network and IT Infrastructure: If the building provides shared Wi-Fi or common network infrastructure, confirm that medical tenant networks are fully isolated. Patient data traversing a shared building network creates HIPAA breach risk. Negotiate a dedicated internet service entry point or a build-out that includes a completely separate network infrastructure.
3. HVAC Requirements for Medical Office Spaces
HVAC is perhaps the most critical and most expensive infrastructure consideration for medical office tenants. Medical spaces have HVAC requirements that are fundamentally different from — and far more demanding than — general office occupancies.
Air Change Requirements
The American Institute of Architects (AIA) Guidelines for Design and Construction of Health Care Facilities and ASHRAE Standard 170 specify minimum air changes per hour (ACH) for various medical spaces:
| Space Type | Min ACH Required | General Office ACH | Notes |
|---|---|---|---|
| General Exam Room | 6 ACH (4 outside air) | 4 ACH | 50% increase over standard office requirement |
| Procedure Room | 15 ACH (3+ outside air) | 4 ACH | Nearly 4x standard office requirement |
| Isolation Room (Negative Pressure) | 12 ACH minimum | N/A | Required for infectious disease, TB precautions |
| Clean Room / Sterile Processing | 20+ ACH | N/A | Positive pressure; ISO classification may apply |
| Waiting Room | 6 ACH | 4 ACH | Higher than office due to mixed patient population |
| Medication Room | 4 ACH (minimum) | N/A | Temperature and humidity control critical |
Dedicated HVAC Systems
Medical offices should negotiate dedicated (not shared) HVAC systems for several reasons:
- Infection control: Shared air handling units can spread airborne pathogens between tenants. Dedicated systems prevent cross-contamination.
- Independent control: After-hours clinical work requires HVAC access without depending on building systems. A dedicated system allows 24/7 climate control at lower cost than paying building after-hours HVAC rates ($25–$75/hour).
- Regulatory compliance: Some state health department licensing requirements for medical facilities mandate dedicated HVAC with documented air change verification.
Temperature and Humidity Control
Medical spaces require tighter temperature and humidity ranges than standard office buildings:
- Temperature: 70–75°F (versus typical building setpoint of 68–76°F) with finer control tolerances
- Relative Humidity: 30–60% RH required in clinical areas; below 30% creates static electricity risk for electronics and increases airborne particle suspension
- Filtration: MERV-13 minimum filtration for general medical occupancies; HEPA filtration (MERV-17) required for immunocompromised patient areas and clean rooms
4. Plumbing Requirements for Medical Offices
Medical office plumbing requirements are substantially more demanding than general office occupancies. A standard office floor plan may have one sink per 10–15 offices; a medical floor plan requires one sink in virtually every patient care area.
Sink Requirements by Space Type
- Exam Rooms: One sink per exam room — non-negotiable for licensed healthcare facilities in most states. Position matters: within arm's reach of the provider's work area, not across the room.
- Treatment/Procedure Rooms: One scrub sink plus one patient sink minimum. Scrub sinks require knee-operated or hands-free faucets for sterile technique.
- Clinical Staff Workstations: Hand hygiene stations required within 6 feet of each clinical workstation per CDC Hand Hygiene Guidelines.
- Soiled Utility Room: Clinical/slop sink required for disposal of soiled materials and instrument cleaning. Requires floor drain and appropriate fixture specifications.
- Clean Utility Room: Separate hand washing sink, isolated from soiled utility areas.
Hot Water Delivery Requirements
Healthcare hot water delivery requirements differ significantly from standard commercial buildings:
- Instant or near-instant hot water delivery (within 10 seconds) is required at all clinical handwashing sinks — building hot water recirculation loops must support this
- ASSE 1070 thermostatic mixing valves are required to deliver hot water at safe temperatures (no scalding risk for patients) while maintaining hot water system temperatures sufficient to prevent Legionella growth
- Confirm the building's water heater capacity and hot water recirculation system can accommodate the increased demand of multiple clinical hand-washing sinks
Medical Gas Systems
For practices performing procedures beyond routine primary care, medical gas systems may be required:
| Medical Gas | Typical Uses | Cost to Install |
|---|---|---|
| Piped Oxygen | Emergency use, respiratory therapy, procedure support | $15,000–$40,000 depending on distance from supply |
| Medical Air | Respiratory procedures, instrument air | $10,000–$25,000 |
| Vacuum/Suction | Dental, surgical suctioning, lab equipment | $8,000–$20,000 |
| Nitrous Oxide | Dental, minor procedural sedation | $5,000–$15,000 (tank-based typically) |
Key Negotiation Point: Negotiate that the landlord will confirm whether medical gas rough-ins exist in the space or building, and that any new medical gas installation will not be classified as "alterations requiring restoration" at lease end. Medical gas systems are permanent improvements that benefit the building — they should not need to be removed.
5. Electrical Requirements for Medical Offices
Medical equipment is power-hungry and sensitive to power quality. Electrical planning must happen before lease signing, because discovering inadequate electrical capacity after you've moved in can cost $50,000–$150,000 to rectify.
- Verify Available Amperage: Standard office: 5–7 watts/SF. Medical: 15–25+ watts/SF. Imaging equipment alone can require 100A dedicated circuits. Verify the building's available electrical capacity before committing.
- Isolated Ground (IG) Circuits: Required for sensitive medical electronics, digital imaging, and EMR workstations. Must be specified in the electrical design before build-out.
- Emergency Power / Generator: State licensing for ambulatory surgical centers and some diagnostic facilities requires emergency generator backup. Verify the building has a generator and whether medical tenants can connect to it.
- Radiology Shielding: X-ray rooms require lead shielding in walls, floors, and ceilings. Lead shielding adds significant weight (structural review required) and cost ($20–$40/SF for shielded areas). This must be planned and approved before construction.
- UPS Systems: Uninterruptible power supplies are required for EMR servers, imaging workstations, and any equipment where an unexpected shutdown could compromise patient safety. Plan UPS locations and load calculations early.
6. ADA and Accessibility Standards for Medical Offices
Medical offices serving patients face stricter ADA compliance requirements than general commercial tenants. The DOJ and HHS have jointly issued guidance stating that healthcare providers must make reasonable modifications to ensure equal access to services — which goes beyond basic ADA structural requirements.
- Accessible Parking: ADA requires one accessible van-accessible space per every 6 accessible spaces. Healthcare facilities should have accessible spaces closest to the main entrance — negotiate this with the landlord before signing.
- Exam Room Clearances: Exam rooms must have a 60-inch turning radius for wheelchair users, with accessible paths to the exam table from both sides. Minimum room size: 120 SF; recommended: 150+ SF for bariatric patients.
- Accessible Check-In Counter: At least a portion of the registration/check-in counter must be no higher than 36 inches and provide knee clearance for wheelchair users.
- Accessible Restrooms Within Suite: Unlike general commercial tenants who can rely on common corridor restrooms, medical practices should have accessible restrooms within the suite for patients with mobility limitations who cannot travel to common restrooms between appointments.
- Door Width and Hardware: All patient-accessible doors must be 32–36 inches clear width. Hardware must be lever-style (not knobs) — operable with a closed fist.
- Accessible Weight Scales: Bariatric and accessible scales with handrails and sufficient floor clearance are required for primary care practices.
7. Hazardous Waste and Infection Control Provisions
Medical offices generate regulated waste streams that require specific lease provisions to ensure the practice can operate legally and the landlord's building is not exposed to liability.
Regulated Medical Waste (RMW)
- Sharps containers, blood-soaked materials, pathological waste, and contaminated items must be disposed of through licensed biomedical waste haulers
- The lease should explicitly permit storage of appropriately labeled and contained RMW within the suite and specify a designated pickup location
- Confirm the lease does not contain a broad "no hazardous materials" clause that would inadvertently prohibit lawful medical waste storage
Pharmaceutical Waste
- Controlled substances, expired medications, and chemotherapy agents require DEA-compliant and EPA-compliant disposal
- The lease should permit storage of properly secured pharmaceutical waste in DEA-compliant containers pending licensed disposal
Infection Control During Construction
If any construction or renovation is occurring in adjacent spaces while your medical practice is open, ICRA (Infection Control Risk Assessment) protocols apply. Negotiate the right to require ICRA compliance from the landlord for any construction that could affect air quality or pathogen dispersal into your occupied space.
8. Healthcare-Specific Lease Terms to Negotiate
-
Healthcare Use and Licensing Contingency.
Include a contingency allowing the tenant to terminate the lease (with a refund of any pre-opening costs) if required healthcare licenses, certifications, or facility approvals are denied or cannot be obtained for the specific space. This is especially important for ambulatory surgical centers, dialysis centers, and imaging facilities that require state Certificate of Need (CON) approval.
-
Permitted Use Clause — Healthcare Scope.
The permitted use clause should cover the full scope of anticipated services — and then some. Include not just current specialty but adjacent services (e.g., "primary care and affiliated specialty services, telehealth, and ancillary services including laboratory and imaging"). Overly narrow permitted use clauses prevent practice expansion without landlord consent.
-
Patient Confidentiality / Landlord Access.
As discussed in the HIPAA section, negotiate specific landlord access protocols to protect patient privacy. Include landlord HIPAA acknowledgment language and requirements for escorted access to any area where patient records are stored or accessible.
-
Signage Rights for Healthcare Practices.
Patient-finding signage is clinically important — patients who can't find the entrance may delay care or abandon visits. Negotiate comprehensive signage rights including: exterior building identification, directory listing, wayfinding signage from parking to entrance, and suite identification signage meeting ADA requirements for accessible identification (raised letters, Braille).
-
Exclusivity for Healthcare Tenants.
Negotiate exclusivity preventing the landlord from leasing to direct competitors in the same building. Define "competitor" by specialty (e.g., "primary care physician practice") rather than broadly ("any medical practice") to ensure the clause is enforceable while not blocking non-competing specialties from the building.
-
After-Hours HVAC at Reasonable Cost.
Healthcare practices frequently have extended hours and may schedule procedures on weekends. Negotiate a fixed after-hours HVAC rate (or dedicated HVAC allowing 24/7 access at no additional charge) rather than the building's standard after-hours rate.
-
Equipment and Infrastructure Restoration Carve-Out.
Negotiate that medical gas systems, lead shielding, specialized plumbing, and electrical upgrades installed by the tenant do not require removal at lease end (treating them as landlord improvements). Removing lead shielding from an x-ray room is extremely expensive — typically $20,000–$60,000 — and leaves a structurally compromised space that few subsequent tenants will want anyway.
