What is medical gas rough-in and who pays for it in a medical lease?

Medical gas rough-in refers to the installation of piping and connection points for medical gases — primarily oxygen (O2), nitrous oxide (N2O), vacuum (suction), and compressed air — throughout the clinical areas of a medical office. A rough-in means the piping is installed in the walls and ceilings but the actual gas supply system (tanks, compressors, manifolds) and outlet stations are not yet installed. Medical gas rough-in costs approximately $3,000–$8,000 per zone or outlet station location. In a well-negotiated medical lease, the landlord provides the medical gas rough-in as part of the base building condition or as a landlord contribution to TI, while the tenant installs the actual gas supply equipment. The distinction matters significantly — a landlord who refuses to provide medical gas rough-in may be offering a space that requires $50,000–$150,000 in additional TI just to establish basic clinical functionality.

Medical Office Lease Considerations: HIPAA, TI Costs, Plumbing & Radiation Shielding

Q: Why do medical office leases cost more to build out than standard office leases?

Medical office build-outs cost $120–180/sf compared to $60–80/sf for standard office because of specialized requirements that don't exist in general commercial construction: enhanced plumbing with procedure room sinks, scrub stations, and sterilization equipment; medical gas rough-in (oxygen, nitrous oxide, vacuum, compressed air systems); HVAC with negative pressure capabilities and enhanced air filtration (HEPA-level in some spaces); radiation shielding for imaging rooms; enhanced electrical for medical equipment (dedicated circuits, isolated power panels in procedure rooms); ADA-enhanced widths for patient mobility equipment; and sound attenuation for patient privacy compliance. Each of these systems adds layers of cost that standard office TI doesn't require.

Q: What radiation shielding is required for a medical office with imaging equipment?

Radiation shielding requirements depend on the type of imaging equipment and local jurisdiction (typically set by state radiation control programs). Common shielding requirements: X-ray rooms typically require 1/16-inch lead lining in walls, floor, and ceiling — adding approximately $15,000–$35,000 to the room construction cost for a standard examination X-ray room. CT scanners require significantly more shielding — often 1/8-inch lead or equivalent concrete — at a cost of $40,000–$120,000 per room. MRI suites don't require radiation shielding but require RF shielding (Faraday cage) to prevent electromagnetic interference, costing $50,000–$200,000 for the shielding enclosure alone. A radiation shielding physicist must be engaged to calculate exact shielding requirements — relying on standard specifications without a physicist review is a regulatory compliance risk.

Q: How does HIPAA affect a medical office lease?

HIPAA doesn't directly regulate commercial real estate leases, but HIPAA compliance requirements create specific physical environment obligations that must be addressed in lease and build-out provisions. The key areas: (1) sound attenuation — HIPAA requires that protected health information (PHI) not be overheard; waiting rooms, check-in areas, and exam rooms must have adequate sound isolation; (2) privacy at reception — the check-in counter and records area must provide visual privacy for patient information; (3) waiting room separation — patients in different clinical categories (infectious disease, mental health) may need separate waiting areas; (4) secure records storage — medical records must be stored in a secure area accessible only to authorized personnel. These requirements affect the lease through TI specifications (soundproofing wall construction, secure room provisions) and through use clause language that should specifically permit all HIPAA-required physical modifications.

Q: What ADA requirements are enhanced for medical offices?

Medical office ADA requirements exceed standard commercial office requirements in several areas: (1) door widths — medical offices must provide 36-inch minimum clear door width (vs. 32-inch for standard offices) to accommodate wheelchairs and patient transport equipment; (2) turning radius — exam rooms must provide a 60-inch diameter turning radius for wheelchairs; (3) exam table transfer space — ADA-compliant exam tables must have transfer surfaces accessible from both sides; (4) accessible parking — medical facilities must provide accessible parking spaces at a ratio higher than standard commercial properties; (5) signage — medical wayfinding must meet ADA signage standards including Braille and high-contrast text. The build-out cost impact of enhanced ADA compliance adds approximately $5–15/sf to medical TI costs versus standard office construction.

Q: What is negative pressure HVAC and when is it required in a medical office?

Negative pressure HVAC maintains air pressure in a room below the pressure in surrounding areas — so that air flows into the room (from the corridor into the patient room) rather than out of it. This prevents airborne contaminants from escaping the room into common areas. Negative pressure rooms are required for: infectious disease examination rooms, isolation rooms in outpatient clinics, certain procedure rooms performing aerosol-generating procedures, and any room where airborne-transmissible diseases may be treated. Negative pressure systems require dedicated HVAC with continuous monitoring, typically adding $15,000–$40,000 per room to construction cost. Positive pressure rooms (where air flows out of the room to protect immunocompromised patients) are required for certain oncology, bone marrow transplant, and surgical suite applications.

Why Medical Office Leases Are Fundamentally Different

Medical and dental tenants are among the most valuable tenants in commercial real estate — they generate stable, long-term occupancy, attract patient traffic that benefits other tenants, and rarely go dark. Landlords know this, which is why the negotiating dynamic for medical office leases can seem counterintuitive: despite being highly desirable tenants, medical practices often face above-market TI requirements, longer approval processes, and more restrictive use clause negotiations.

The reason is cost and permanence. Medical build-outs are expensive, heavily regulated, and difficult to repurpose. A landlord who contributes $150/sf in TI to a medical tenant (versus $70/sf for a standard office tenant) is taking a much larger financial risk on that tenancy. The quid pro quo for higher TI is typically a longer initial term (10–15 years), strong personal guarantee provisions, and more detailed build-out approval requirements.

TI Cost Reality: Medical vs. Standard Office

Medical Office vs. Standard Office TI Cost Comparison — 4,000 sf Suite

STANDARD OFFICE BUILD-OUT (4,000 sf)
Demo + framing: $ 8/sf = $32,000
Drywall + finish: $12/sf = $48,000
Flooring (carpet/LVT): $ 8/sf = $32,000
Ceiling (grid + tile): $ 6/sf = $24,000
Electrical (standard): $10/sf = $40,000
Plumbing (break room only): $ 4/sf = $16,000
HVAC (standard office): $10/sf = $40,000
Doors + hardware: $ 5/sf = $20,000
Paint + millwork: $ 5/sf = $20,000
GC overhead + profit (15%): $10/sf = $40,500
TOTAL: $78/sf = $312,500

MEDICAL OFFICE BUILD-OUT (4,000 sf — primary care/GI)
Demo + framing (reinforced): $ 10/sf = $ 40,000
Drywall + finish (soundproof): $ 18/sf = $ 72,000
Flooring (medical-grade LVT/VCT): $ 10/sf = $ 40,000
Ceiling (lay-in, cleanable): $ 8/sf = $ 32,000
Electrical (dedicated circuits): $ 16/sf = $ 64,000
Plumbing (exam room sinks + WC): $ 22/sf = $ 88,000
Medical gas rough-in (O2, vac, air):$ 8/sf = $ 32,000
HVAC (enhanced filtration + zones): $ 20/sf = $ 80,000
Doors + hardware (36" wide, ADA): $ 8/sf = $ 32,000
Sterilization/soiled utility rooms: $ 5/sf = $ 20,000
ADA compliance + signage: $ 5/sf = $ 20,000
GC overhead + profit (15%): $ 20/sf = $ 78,000
TOTAL: $150/sf = $598,000

Premium over standard office: $286,000 (92% more)

Add imaging equipment (X-ray room, fluoroscopy, CT, MRI) and the medical TI cost can reach $180–220/sf for specialty practices — more than triple standard office build-out costs. These numbers are why TI allowance negotiation is the most financially consequential item in a medical office lease, often more important than the base rent.

Enhanced Plumbing Requirements for Medical Offices

Clinical Sink Requirements

Standard office space typically has one or two wet columns feeding a break room sink and restrooms. Medical office spaces require plumbing at virtually every exam room — a 10-exam-room practice may need 10–15 clinical sinks distributed throughout the floor plan.

Clinical sink types in medical office build-outs:

Exam room hand wash sinks: Required in every examination room under most state health department standards. Each requires hot and cold water supply, drain, and in some jurisdictions, foot or sensor controls for hands-free operation. Cost: $800–$1,500 per sink plus rough-in plumbing.
Procedure room sinks (deep): Procedure rooms and minor surgery suites require deep surgical sinks with hands-free controls. Cost: $2,500–$5,000 per sink including rough-in.
Scrub sinks: Multi-station scrub sinks for surgical and procedure suites — typically stainless steel, knee or elbow operated. Cost: $3,000–$8,000 per station.
Utility sinks (soiled and clean utility): Every medical suite requires dedicated soiled utility rooms (for disposing of clinical waste) and clean utility rooms (for medical supply storage), each with dedicated plumbing. Cost: $1,500–$3,000 per room.
Sterilizer/autoclave connections: Steam sterilizers require dedicated hot and cold water connections, drain lines, and often steam supply. Cost: $3,000–$8,000 per unit location.

Plumbing Capacity and Building Infrastructure

Many office buildings — including those marketed as "medical office" — have plumbing infrastructure (supply mains, drain stack locations, water heater capacity) sized for standard office use. A medical practice with 10 exam rooms and multiple procedure rooms may require a 50–100% increase in domestic hot water capacity over what the building's standard infrastructure provides. Always request a plumbing capacity assessment from a licensed medical plumbing engineer before signing a medical lease in a converted office building.

Medical Gas Systems

What Medical Gases Are Needed

Most primary care, specialty, and surgical practice offices require some combination of the following medical gas systems:

Gas Type	Common Uses	Who Typically Needs It	Rough-In Cost (per outlet)
Medical Oxygen (O2)	Patient supplemental O2, anesthesia	All clinical practices	$800–$1,500
Medical Vacuum (suction)	Suctioning secretions, surgical aspiration	All clinical practices	$600–$1,200
Medical Compressed Air	Dental handpieces, ventilators, nebulizers	Dental, pulmonology, surgery	$600–$1,200
Nitrous Oxide (N2O)	Analgesia, dental sedation	Dental, pain management, OB/GYN	$800–$1,500
Nitrogen (N2)	Powering surgical instruments	Orthopedic surgery centers	$800–$1,500

The Medical Gas Rough-In vs. Full System Distinction

"Medical gas rough-in" means the piping and outlet stub-outs are installed in the walls during construction, but the gas supply equipment (bulk oxygen tank, vacuum pump, manifold systems) is not yet connected. The tenant installs the actual supply equipment as part of their equipment package, then connects to the landlord-provided rough-in.

Why this distinction matters: Landlords who provide only medical gas rough-in (piping in walls) have fulfilled their obligation — the tenant still needs to purchase and install the supply equipment. A vacuum pump for a medical office costs $8,000–$25,000. A medical oxygen delivery system (manifold connecting to medical-grade O2 cylinders) costs $3,000–$8,000. Budget for this equipment separately from the build-out TI.

Radiation Shielding: X-Ray, CT, and MRI Requirements

Regulatory Framework

Radiation shielding requirements for medical imaging rooms are set by state radiation control programs (not federal), with guidance from the National Council on Radiation Protection (NCRP). The specific shielding requirement depends on:

Equipment type (X-ray, fluoroscopy, CT, mammography, nuclear medicine)
Equipment energy level (kVp for X-ray, energy level for nuclear medicine)
Workload (how many patients are imaged per week)
Occupancy of adjacent areas (a room adjacent to an occupied patient waiting area requires more shielding than one adjacent to a utility closet)
Whether the room has controlled access (staff present) or uncontrolled access (patients and public)

Radiation Shielding Cost by Equipment Type

Radiation Shielding Build-Out Cost by Imaging Room Type

Standard X-ray room (general radiography):
Lead equivalent: 1/16" Pb (1.6mm lead)
Method: Lead-lined drywall or lead-painted drywall
Build-out premium: $15,000 – $35,000 per room

Fluoroscopy room (interventional):
Lead equivalent: 1/16" – 1/8" Pb
Build-out premium: $25,000 – $60,000 per room

CT scanner room:
Lead equivalent: 1/8" – 1/4" Pb or baryte (heavy) concrete
Build-out premium: $40,000 – $120,000 per room

MRI suite (RF shielding, not radiation):
Method: Faraday cage (copper or aluminum sheet)
Build-out premium: $50,000 – $200,000 (depends on magnet strength)

Nuclear medicine room:
Lead equivalent: Custom calculation by medical physicist
Build-out premium: $30,000 – $80,000 per room

Note: All shielding designs must be calculated and stamped by a
licensed medical physicist. Estimated cost: $3,000–$8,000 per room.

Lease Provisions for Imaging Rooms

Leases for spaces with imaging equipment require several specialized provisions:

Structural assessment for equipment weight: CT scanners weigh 4,000–8,000 lbs; MRI systems weigh 8,000–30,000+ lbs. Floor load calculations and structural engineering approval must be part of the TI approval process.
Landlord consent for shielding installation: Lead lining is a permanent modification. Confirm that the lease expressly permits installation and that removal (if required upon lease expiration) is addressed — lead removal is expensive and creates hazardous waste disposal requirements.
Cooling capacity for MRI: MRI systems generate significant heat from gradient coil cooling. The building's HVAC system must provide supplemental cooling capacity, often requiring dedicated chiller installations.
Vibration isolation for CT and MRI: CT scanners and MRI systems are sensitive to vibration. Buildings near HVAC equipment, elevators, or high-foot-traffic areas may require vibration isolation platforms.

HVAC: Negative Pressure, Enhanced Filtration, and Clinical Zoning

Negative Pressure Requirements

Negative pressure rooms — where air flows from the corridor into the room, preventing airborne contaminants from escaping — are required for:

Isolation rooms in infectious disease and pulmonology practices
Examination rooms seeing patients with suspected airborne illness (TB, measles, COVID-19)
Procedure rooms performing aerosol-generating procedures (bronchoscopy, intubation)
Certain oncology and transplant outpatient spaces may require positive pressure (clean rooms) to protect immunocompromised patients

A negative pressure room requires its own dedicated exhaust, typically to the exterior of the building (not recirculated through the building's common HVAC system). The cost per negative pressure room — dedicated exhaust fan, ducting to exterior, pressure monitoring equipment, and interlocked controls — is typically $15,000–$40,000 above standard exam room HVAC.

Enhanced Filtration Standards

Medical offices often require MERV-13 or higher filtration (HEPA filtration in surgery centers and isolation rooms) — significantly more expensive to operate and maintain than standard MERV-8 commercial filtration. Confirm with the landlord whether the building's HVAC can accommodate enhanced filtration without system redesign. Standard air handlers often cannot handle HEPA filters due to airflow resistance.

HVAC Zoning for Clinical Areas

Medical offices require more HVAC zones than standard commercial spaces — each clinical area (waiting, exam, procedure, lab) may require independent temperature and humidity control. A 4,000 sf medical practice might need 8–12 HVAC zones versus 3–4 zones for equivalent standard office space. More zones mean more thermostats, more variable air volume (VAV) boxes, and significantly more control wiring — adding $20–35/sf to HVAC costs versus standard office systems.

HIPAA Considerations in Medical Lease Provisions

Sound Attenuation for Patient Privacy

HIPAA's Privacy Rule requires covered entities to protect patient health information (PHI) from incidental disclosure. In a physical environment, this primarily means ensuring that patient conversations in exam rooms, at check-in counters, and in waiting areas cannot be overheard by other patients or the general public.

Practical lease and build-out implications:

Exam room wall construction: Standard metal stud with single-layer drywall (STC 35–40) is insufficient for HIPAA privacy. Medical practices typically require STC 45–50 construction (double-layer drywall with resilient channels and batt insulation) at an additional cost of $5–8/sf of partition length.
Reception and check-in counter design: The check-in counter must be configured to prevent other patients from viewing the screen or hearing conversations about PHI. This typically requires a raised privacy screen and angled counter design.
Sound masking systems: Many medical offices install sound masking (white noise) systems — small speakers in the ceiling that emit background noise to make speech less intelligible. System cost: $3–5/sf of space covered.

Use Clause Language for HIPAA Compliance

The lease's permitted use clause should specifically authorize all HIPAA-required physical modifications and operational practices, including:

Installation of sound masking systems (common landlord concern about electrical load and ceiling modifications)
Secure medical records storage and disposal (shredding services, locked records rooms)
Installation of monitoring systems and controlled-access door hardware in clinical areas
Electronic health record (EHR) infrastructure (structured cabling, server room requirements)

ADA Enhanced Standards for Medical Offices

Where Medical ADA Exceeds Standard Commercial Requirements

Requirement	Standard Commercial ADA	Medical Office Standard	Cost Premium
Door clear width	32" minimum	36" minimum (gurney/wheelchair)	$200–$400 per door
Exam room turning radius	60" circle (standard)	60" circle + side transfer space	Larger room footprint
Accessible restrooms	One per floor	Patient-accessible in clinical area	Additional plumbing rough-in
Parking accessible spaces	1:25 standard ratio	1:6 for medical uses (recommended)	More accessible spaces
Signage	Standard ADA signs	ADA + wayfinding for medical areas	$3,000–$8,000 for full suite

Biomedical Waste Disposal Provisions

Medical tenants generate regulated biomedical waste (sharps, contaminated materials, laboratory waste) that requires specialized disposal by licensed waste haulers. The lease should address:

Designated waste storage area: Biomedical waste must be stored in a secure, lockable area accessible only to authorized personnel. The lease should allocate space for a biomedical waste storage room (typically 50–100 sf) or storage closet.
Loading dock or exterior access: Waste haulers typically require rolling cart access from the clinical area to an exterior pick-up point. In multi-tenant medical office buildings, a shared biomedical waste staging area is often provided.
Lease disclosure requirements: Most commercial leases require tenants to notify the landlord of hazardous materials storage. Biomedical waste typically falls within the lease's hazardous materials definition — ensure the permitted use clause expressly carves out regulated medical waste generated in the ordinary course of clinical practice.

6 Red Flags in Medical Office Leases

🛑 Red Flag 1: TI Allowance Insufficient for Medical Build-Out Without Landlord Acknowledgment

A landlord who offers $70–80/sf TI for a medical tenant — standard office TI — without acknowledging that medical build-outs cost $120–180/sf is either uninformed or expecting the tenant to absorb the gap. Before accepting any medical TI offer, budget your specific build-out costs with a medical construction estimator. If the TI gap is significant, negotiate additional TI, landlord-paid improvements (medical gas rough-in, plumbing upgrades), or rent abatement to offset the unfunded build-out cost.

🛑 Red Flag 2: Use Clause That Doesn't Specifically Permit Clinical Practice

A permitted use clause that says "general office use" — or even "medical office use" without specificity — may not cover all clinical activities you need to conduct, including: dispensing medications, performing procedures requiring local anesthesia, using certain diagnostic equipment, or operating a lab. Define your permitted use specifically: "the practice of [specialty] medicine and all related clinical, diagnostic, administrative, and ancillary healthcare services, including but not limited to [specific procedures]."

🛑 Red Flag 3: No Landlord Obligation for Plumbing Capacity Upgrades

If the building's existing plumbing infrastructure can't support your clinical sink and utility requirements, and the lease is silent on who pays for infrastructure upgrades, the default is the tenant. Negotiate an explicit landlord obligation to provide adequate plumbing capacity to the suite — meaning the supply and drain infrastructure serving your space must be sufficient for medical use before your TI work begins.

🛑 Red Flag 4: Radiation Shielding Listed as Tenant's Removal Obligation

Some landlords require tenants to remove all alterations upon lease expiration — including radiation shielding. Lead lining removal is expensive ($8–15/sf of shielded area), creates hazardous waste disposal obligations, and leaves walls in worse condition than before the shielding was installed. Negotiate that radiation shielding is a permitted alteration that survives lease expiration — the landlord retains a shielded room that is more valuable (more marketable to the next medical tenant) than an unshielded one.

🛑 Red Flag 5: HVAC Maintenance Clause That Puts Replacement on Tenant

Medical offices push HVAC systems much harder than standard offices — higher air change requirements, continuous operation of exhaust systems, and frequent filter changes. A lease that puts all HVAC maintenance AND replacement on the tenant creates an unquantifiable long-term liability. Landlords should retain responsibility for HVAC unit replacement (capital) while tenants handle filters, routine maintenance, and belt/motor replacement (maintenance). This distinction can mean a $15,000–$40,000 difference when a rooftop unit fails in Year 7.

🛑 Red Flag 6: Assignment Restrictions That Prevent Practice Sale

Medical practices are typically sold as going concerns — a physician selling their practice to a hospital system, a larger group, or a retiring partner needs to assign the lease as part of the transaction. Standard commercial lease assignment provisions require landlord consent for every assignment. Medical tenants should negotiate a "permitted assignment" carve-out for transfers to: (1) a professional entity controlled by the same licensed practitioners; (2) a successor entity that acquires substantially all the tenant's medical practice; and (3) a hospital or health system that operates the practice as a going concern. Without these carve-outs, a practice sale can be blocked or delayed by landlord consent requirements at the worst possible time.

✅ 12-Item Medical Office Lease Negotiation Checklist

Commission a medical build-out cost estimate: Get a contractor or healthcare construction consultant to estimate your specific build-out cost before lease negotiation — this number drives your TI allowance requirement and is non-negotiable based on operational needs
Negotiate medical-adequate TI: Benchmark your TI request against current market medical TI ($100–160/sf in most major markets) and negotiate the gap between landlord's offer and your actual need as landlord-performed work, abatement, or additional allowance
Define permitted use specifically: List every clinical activity, procedure, diagnostic service, and ancillary healthcare activity you intend to conduct — generic "medical office use" is insufficient for practices with specialty procedures
Secure landlord warranty of plumbing capacity: Require the landlord to warrant that the building's plumbing infrastructure can support your clinical program before you begin TI work — include a remediation obligation if capacity is insufficient
Address medical gas rough-in as a landlord obligation: For clinical practices requiring O2, vacuum, or compressed air, negotiate medical gas rough-in as part of the landlord's base building delivery obligation or as a landlord-funded TI item
Get radiation shielding specifically permitted: The lease should expressly permit installation of radiation shielding and specify that it survives lease expiration without removal obligation (or with a capped removal obligation)
Negotiate HVAC capital replacement as landlord's obligation: The landlord should be responsible for HVAC unit replacement; the tenant handles routine maintenance and filter changes
Include HIPAA sound attenuation standards in the work letter: The work letter (or TI specifications) should include minimum STC ratings for exam room walls — don't leave wall construction specifications to the landlord's standard practice
Carve out biomedical waste from hazardous materials restrictions: Ensure the lease's hazardous materials prohibition expressly excludes regulated medical waste generated in the ordinary course of clinical practice
Negotiate ADA-compliant door widths as base building condition: All doors in the clinical area should be 36" wide as a landlord-provided base building condition, not a TI item
Add a permitted assignment provision for practice sales: Define permitted assignments that don't require landlord consent to include transfers in connection with a sale of the medical practice or a merger with another healthcare entity
Confirm parking ratio adequacy for medical use: Medical offices generate patient traffic that may require a higher parking ratio than standard office. Confirm the building's parking supply is adequate for your patient volume and negotiate a parking ratio covenant if necessary

Frequently Asked Questions

Why do medical office leases cost more to build out than standard office leases?

Medical build-outs cost $120–180/sf versus $60–80/sf for standard office because clinical practice requires: exam room sinks at every room (versus a single break room sink), medical gas rough-in throughout clinical areas, enhanced HVAC with higher air changes and potential negative pressure rooms, ADA-enhanced door widths and turning radii, sound attenuation for HIPAA compliance, sterilization and soiled utility room infrastructure, and potential radiation shielding for imaging. Each of these systems adds cost that doesn't exist in standard office construction — a 4,000 sf medical build-out can easily exceed standard office costs by $280,000 or more.

What is medical gas rough-in and who pays for it?

Medical gas rough-in is the installation of piping and outlet stub-outs (for O2, vacuum, compressed air, nitrous oxide) in the walls and ceilings during construction, before the gas supply equipment is installed. Cost: $3,000–$8,000 per outlet location. In well-negotiated medical leases, the landlord provides rough-in as a base building condition or landlord-funded TI item; the tenant installs gas supply equipment. If the landlord won't fund rough-in, negotiate rent abatement to offset the tenant's cost — a 6-zone medical gas system rough-in can cost $30,000–$50,000 before supply equipment.

What radiation shielding is required for a medical office with imaging equipment?

Shielding requirements are set by state radiation control programs and calculated by a licensed medical physicist. General benchmarks: standard X-ray room adds $15,000–$35,000 in shielding costs; CT scanner room adds $40,000–$120,000; MRI suite requires RF shielding (Faraday cage) at $50,000–$200,000 (not radiation shielding). All shielding must be designed and stamped by a medical physicist ($3,000–$8,000 per room). Negotiate the right to install shielding as a permitted alteration that survives lease expiration — avoid removal obligations that would require expensive lead abatement.

How does HIPAA affect a medical office lease?

HIPAA's Privacy Rule creates physical environment requirements for protecting patient health information: exam room walls must achieve STC 45–50 sound ratings (double drywall construction); reception counters need privacy screens; waiting areas may need sound masking ($3–5/sf). These requirements must be addressed in the TI work letter and specifications. The permitted use clause should expressly authorize all HIPAA-required physical modifications, including sound masking systems, controlled-access hardware, and secure records storage — many of which may require landlord consent under standard lease language.

What ADA requirements are enhanced for medical offices?

Medical offices must provide 36" clear door widths (vs. 32" standard), 60" turning radii with side transfer spaces in exam rooms, patient-accessible restrooms within the clinical area, higher accessible parking ratios, and ADA wayfinding signage for healthcare settings. Enhanced ADA compliance adds approximately $5–15/sf to medical TI costs. Negotiate 36" door widths as a base building condition provided by the landlord — these are structural building elements that shouldn't be charged against the tenant's TI allowance.

What is negative pressure HVAC and when is it required in a medical office?

Negative pressure maintains air pressure below surrounding areas so air flows into the room (not out), preventing airborne pathogens from escaping. Required for isolation rooms, infectious disease exam rooms, and rooms performing aerosol-generating procedures. Cost per room: $15,000–$40,000 above standard exam room HVAC, including dedicated exhaust to the exterior, pressure monitors, and interlocked controls. Positive pressure (clean rooms) is required for immunocompromised patient care. Both require their own HVAC circuits — confirm the building can accommodate the required exhaust penetrations and additional mechanical equipment before executing the lease.
