A medical office building (MOB) fit-out looks like a standard commercial office project from the outside. Inside the wall cavity, it is a different construction type — more plumbing fixtures per square foot than any other office occupancy, stricter ADA clearance requirements than a standard office, sound attenuation between exam rooms that standard drywall assemblies do not achieve, and regulatory exposure under both the Florida Building Code and the Florida Agency for Health Care Administration (AHCA) if any procedures are performed on site.

Hiring a GC without MOB experience for this type of project produces a punch list dominated by code compliance items. This article covers what makes an MOB fit-out different from a standard commercial fit-out and what a medical practice owner needs to know before construction starts.

ADA Requirements for Medical Office Space

The Americans with Disabilities Act (ADA) applies to all commercial spaces open to the public, but medical facilities have specific application standards that go beyond the baseline requirements for a standard office.

Exam Room Clearances

Every exam room in a medical office must accommodate a wheelchair-using patient. The ADA requires a 60-inch turning radius (T-turn or full rotation) in every accessible space — but for exam rooms, the practical requirement is a clear path from the door to the exam table and enough floor area to position the chair adjacent to the table.

ADA's exam table standard (from the 2010 ADA Standards for Accessible Design, Section 902) requires accessible exam tables. The examination space adjacent to the table must allow a 60-inch clear circle or a T-turn area. For a standard 10×12 exam room with a sink and supply storage, this is tight. The room layout must be planned with the ADA clearance overlay before framing begins — not adjusted after drywall is hung.

Door Hardware and Width

All patient-accessible doors in a medical office must have lever hardware (not round knob), and must be a minimum of 32 inches clear width in the open position. A 36-inch door with a standard 1.75-inch door thickness provides 34.25 inches clear — compliant. A 32-inch door provides only 30.25 inches clear — not compliant.

Exam room, restroom, and all patient-zone door hardware must be reviewed against the ADA standard before hardware schedule is finalized.

Patient Restroom

The ADA patient restroom requires:

In a multiple-provider medical office, separate male/female restrooms may be required by code depending on occupant load. Confirm the restroom count requirement with the building department and with AHCA if the practice is licensed.

Plumbing: Hand Sinks by Infection Control Standards

Medical office plumbing is driven as much by infection control standards as by code. The CDC's Guidelines for Environmental Infection Control in Health-Care Facilities and CMS Conditions of Participation (if the practice bills Medicare or Medicaid) require hand sinks within easy reach of every exam room to support hand hygiene between patients.

Hand Sink Count and Placement

The practical standard for medical office construction: one hand sink per exam room, located near the exam room door and accessible without the provider having to walk past the patient. In a practice where providers move from room to room between patients, the hand sink placement must allow hand hygiene on the way in and on the way out of the room.

For a 5-exam-room practice, this means 5 exam room hand sinks plus a sink at the nurse's station, a sink in the break room, and restroom lavatories. Plumbing supply and drain rough-in for all of these must be in the slab or in the wall framing before drywall — not as a late add.

Hot Water at Exam Room Sinks

Exam room hand sinks must have both hot and cold water. Hot water must reach the faucet within a reasonable time — typically within 30 seconds of opening the valve. For a large practice with exam rooms far from the water heater, a recirculating hot water system or a point-of-use electric water heater at each sink may be required to meet this expectation. Plan it before rough-in, not after.

Medical Gas for Procedure Rooms

Not all medical offices require medical gas. General practice, pediatrics, and most outpatient specialty offices operate without it. But if the practice includes any of the following, medical gas rough-in is required:

Medical gas systems — oxygen, nitrous oxide, medical air, vacuum — are designed and installed per NFPA 99 (Health Care Facilities Code). This requires:

Medical gas installation requires a specialty subcontractor qualified under NFPA 99. It is not in scope for a standard plumbing contractor. Plan the subcontractor selection and lead time during preconstruction.

HIPAA Sound Attenuation: STC Ratings for Exam Room Walls

HIPAA's Privacy Rule requires reasonable safeguards to prevent inadvertent disclosure of protected health information (PHI). While HIPAA does not specify a numeric sound transmission coefficient (STC) rating, the practical standard in MOB construction is STC 45–50 between exam rooms and between exam rooms and corridors.

What Standard Drywall Achieves

A standard single-layer drywall partition (3.5-inch stud, one layer 5/8-inch drywall each side) achieves approximately STC 33–35 — adequate for a standard office but not for a medical exam room where patient-provider conversations should not be audible in adjacent rooms.

How to Achieve STC 45–50

Options, from simplest to most complex:

The key detail: partition walls must extend from slab to deck, not just from floor to suspended ceiling. A partition that stops at the ceiling plane allows sound to travel over the wall through the plenum and into adjacent rooms — defeating the entire assembly.

Specify "slab-to-deck" in the partition schedule for all patient-zone walls. This adds cost (more stud material, blocking at the structure above the ceiling), but it is the only way to achieve the required STC performance.

JK Prestige's commercial renovation team specifies slab-to-deck construction on all medical office exam room partitions and documents STC ratings in the specification prior to framing.

HVAC for Medical Office: Exam Room Comfort and Privacy

Temperature Control by Zone

Patients undress in exam rooms. A 70°F exam room that feels comfortable fully clothed feels cold to a patient on an exam table in a paper gown. Medical office HVAC should provide independent temperature control by room — not a single zone thermostat for a row of exam rooms. Variable air volume (VAV) boxes with room-level thermostats are the standard approach for a medical office of any size.

Exhaust Air in Patient Bathrooms and Procedure Rooms

Patient bathrooms require exhaust fans vented to the exterior — not to the plenum. Procedure rooms may require 100% outside air (no recirculation) depending on the procedure type and any regulatory requirements under AHCA.

For practices that perform in-office procedures, confirm HVAC design requirements with the AHCA planner and with the infection control standards applicable to the procedure type before design is finalized.

Florida AHCA Requirements for Licensed Health Care Facilities

The Florida Agency for Health Care Administration (AHCA) has jurisdiction over any health care facility that is licensed by AHCA — ambulatory surgery centers, clinical laboratories, birth centers, and some outpatient procedure facilities.

A standard medical office practice — physician, dentist, therapist — is not AHCA-licensed and is not subject to AHCA construction review. But the line is not always obvious:

If there is any possibility that the practice will be AHCA-licensed, engage an AHCA plan review consultant before architectural design begins. AHCA construction standards (square footages, traffic patterns, ventilation rates) are significantly more prescriptive than the Florida Building Code alone, and retrofitting to meet them after a build-out is complete is expensive.

Frequently Asked Questions

Why does a medical office fit-out need more plumbing than a typical office build-out?
Infection control standards, including the CDC's guidelines and CMS Conditions of Participation for practices that bill Medicare or Medicaid, call for a hand sink in or near every exam room so providers can wash their hands between patients. For a five exam room practice that means five exam room sinks plus sinks at the nurse's station, the break room, and the restrooms, all with hot and cold water reaching the faucet within about 30 seconds. All of that supply and drain rough-in has to be planned into the slab or wall framing before drywall goes up, not added later.
Why can't we just use standard drywall between exam rooms?
A standard single layer drywall partition only achieves an STC rating of about 33 to 35, which is fine for a normal office but not enough to keep patient-provider conversations from being overheard in the next room, a HIPAA privacy concern even though HIPAA does not specify an exact number. The practical target in medical office construction is STC 45 to 50, reached with double layer drywall and resilient channel, a staggered-stud partition, or mineral wool insulation in the cavity. The detail that actually makes it work is that the partition has to run slab to deck, not just up to the suspended ceiling, because sound will travel over the wall through the plenum otherwise.
Does our practice need to worry about AHCA, or is that only for hospitals?
A standard physician, dentist, or therapist office is generally not AHCA-licensed and is not subject to AHCA construction review. But if the practice includes an ambulatory surgery center, an office surgery setting where a physician performs procedures under general anesthesia or sedation, or a clinical laboratory, AHCA licensing and its construction review under Florida Administrative Code Chapter 59A-5 can apply. If there is any chance your practice falls into one of those categories, get an AHCA plan review consultant involved before architectural design begins, since AHCA's space and ventilation standards are more prescriptive than the Florida Building Code alone and are expensive to retrofit after the build-out is done.
