What drives surgery center and endoscopy center construction cost in Texas
By Structures and Interiors.
An ambulatory surgery center or endoscopy center is among the most expensive kinds of outpatient space to build. The rooms are defined by licensing standards, and the mechanical, electrical, and medical gas systems are sized and tested to them. Below we cover what drives the cost in Texas, in a new building and in a leased or converted one, what sets the schedule through licensing, and what a construction price usually leaves out.
It does not list prices per square foot. Costs move with materials, labor, and the specific building, so S&I gives each project a first budget at no charge and a detailed estimate later from the drawings.
This guide does not give week counts either. How long each phase takes depends on the space or site, the city, and the lead times on equipment and building systems. The table below shows what sets the time in each phase, and S&I works out the calendar for your project alongside the first budget.
Where you start sets the cost
The building or site you start with sets the cost as much as the number of rooms does.
| Project type | What it means | What moves the cost |
|---|---|---|
| Endoscopy center in shell space | Procedure rooms, scope reprocessing, and recovery built new in an empty suite or building shell. | The number of procedure rooms, scope reprocessing, the air system and medical gas, and whether the shell has the height, roof structure, and electrical service the center needs. |
| Surgery center in shell space | Operating rooms, sterile processing, pre-op, and recovery built new in a shell designed to take them. | The number and class of operating rooms, sterile processing, the air handling equipment, emergency power, and medical gas. |
| Conversion of an existing building or suite | Second-generation office, medical, or retail space rebuilt as a licensed center. | Whether the building has room above the ceiling for ductwork, roof structure for air handling units, enough electrical service, and space outside for a generator and medical gas. |
| Addition or renovation in an operating center | Adding a room or renovating while the center keeps taking cases, in phases. | Hard barriers and negative pressure, shutdowns of medical gas, power, and air around the surgery calendar, and an inspection before each phase is used. |
| New building | A freestanding surgery or endoscopy center on its own site, including site work, the shell, and the interior. | Site work and utilities, the city's site approvals, a shell designed for the mechanical loads, and then everything a finish-out includes. |
Many centers are built with a clinic attached. The clinic portion costs far less to build than the licensed suite, so a single blended price for the whole building can mislead. Ask for the two priced separately.
What drives the cost
The building you start with
Conversions of ordinary commercial space are where budgets go wrong. Surgery center air handling equipment and ductwork are much larger than an office system, and they need height above the ceiling, structure on the roof, electrical capacity, and room outside for a generator and medical gas. A second-generation suite that lacks those can cost more to convert than a shell costs to finish. Check the building before the lease or purchase is final.
Ventilation and air changes
ASHRAE 170, the ventilation standard for health care facilities, and the Texas licensing rules set the air changes, filtration, temperature, humidity, and pressure for each room. An operating room moves several times the air of an office, held at positive pressure, with humidity controlled through a North Texas summer. The mechanical system is among the largest costs in the project.
Operating rooms versus procedure rooms
The class of room follows from the procedures and the level of anesthesia planned, and it sets the room's size, finishes, and air. The number of operating rooms moves the cost more than the square footage does. An endoscopy center, built around procedure rooms and scope reprocessing, generally costs less than a multi-specialty surgery center of the same size.
Medical gas
Oxygen, medical air, nitrous oxide, surgical vacuum, and waste anesthetic gas disposal are piped under NFPA 99 by credentialed installers and tested by an independent verifier. The cost follows the number of outlets, the source equipment, and where it is housed.
Emergency power and life safety
A center needs an essential electrical system with a generator and transfer switches, fire-rated walls and smoke barriers, and fire alarm and sprinkler systems designed for a health care occupancy. Generators and switchgear are also among the slowest items to arrive.
Equipment rough-ins
Surgical lights and booms need steel support above the ceiling designed for the specific product. Sterilizers and washers bring steam or heavy electrical loads, treated water, and drains. When vendors are chosen late, the steel, ductwork, and ceilings are either guessed at or built twice.
Shielding
Orthopedic, spine, and pain management cases use fluoroscopy, and those rooms may need lead shielding built to a physicist's design.
Finishes
Operating and procedure rooms need seamless, cleanable floors and walls and ceilings suited to the class of room. Waiting, pre-op, and recovery areas leave more choice. In a surgery center, finishes are a smaller share of the cost than the systems behind them.
Licensing and inspections
A licensed center is inspected by the city and then by the state before it can take cases, and the independent tests of the medical gas, air balance, and emergency power have to be complete and documented. A correction found at the state inspection costs far more than the same correction made in design, so the licensing requirements belong in the drawings from the start. See ASC construction and licensing steps in Texas.
Accessibility
The Texas Accessibility Standards apply to a surgery center as they do to any commercial project, and the project is registered with the Texas Department of Licensing and Regulation (TDLR), then reviewed and inspected by a registered accessibility specialist.
The tenant improvement allowance
In a leased building, an allowance sized for medical office space covers a small share of a surgery center. Read the work letter to see what the landlord delivers, such as roof structure, electrical service, and a pad for the generator. Read what the allowance may be spent on and when it is paid. Settle who owns the generator, the air handling equipment, and the medical gas system at the end of the lease.
Site work and utilities on a new building
A freestanding surgery or endoscopy center adds what a lease space already has: grading, paving and parking, storm drainage and detention, and water, sewer, electric, and gas service brought to the building. These costs follow the site, not the size of the building, so a small building on a difficult lot can cost more than a larger one on a ready pad. A center also needs room on the site for the generator, medical gas storage, and delivery access, and city site plan approval comes before the building permit. Our guide to leasing and site obstacles covers what to check before you buy.
Phasing an operating center
Adding a room while the center treats patients means hard barriers, negative pressure in the construction area, exits kept open, and shutdowns of medical gas, power, and air scheduled around the surgery calendar. Each phase may need its own inspection before it is occupied. We plan the phases and shutdowns with the center's administrator before work starts, and where feasible shutdowns are done outside surgery hours. Phasing and after-hours work add cost and time. The trade-off is that the center keeps taking cases.
Schedule and permitting
Time costs money on both sides of the contract. Every week of design, permit review, and inspections is a week of rent or loan interest before the first patient, and a longer job carries more supervision and general conditions. Generators, switchgear, and air handling units can set the finish date, and the state's review and inspection sit between the city's certificate of occupancy and the first case. From the first concept we often schedule design, permitting, and construction together, and order long-lead items as early as the design allows.
How long it takes
A surgery center is finished when the state licenses it, not when the city signs off. The schedule has to show both, because every week between them is a week of rent and staff with no cases.
| Phase | What sets the time: existing building or lease space | What sets the time: new building |
|---|---|---|
| Design and equipment selection Drawings, with lights, booms, sterilizers, and imaging chosen early enough to design around. | The number of operating and procedure rooms, the condition of the building, and how early lights, booms, sterilizers, and imaging are chosen. | The same choices as an existing building, plus the site, the building shell, and the exterior design. |
| Site approvals Platting, site plan approval, and any owner association review. | Not usually required | The city's platting and site plan process, its meeting calendar, and any owner association review. Often longer than construction. |
| State and city review Review by the architectural review unit of the Texas Health and Human Services Commission (HHSC), the city permit, the fire marshal, and TDLR registration. | HHSC architectural review alongside the city permit, and how many comments come back from each for correction. | The same as an existing building, with the site and the whole building under review. |
| Construction and testing From permit to city final, including medical gas verification, air balancing, and fire alarm and generator tests. | The mechanical, emergency power, and medical gas work and its testing, the condition of the existing building, and equipment lead times. | Site work, weather, and the building shell come first, then the same interior work and testing. Generators, air handlers, and electrical gear can set the finish date. |
| City final Final inspections and the certificate of occupancy. | How quickly the city and fire inspectors can be scheduled, and how cleanly the test reports and last items close out. | The same as an existing building, with the site and the whole building inspected. |
| State inspection and license The state's final architectural inspection and the license. Led by the owner's team. | The state's inspection calendar and the owner's license application. | The same as an existing building: the state's inspection calendar and the owner's license application. |
| Medicare survey or accreditation Led by the owner's team, after the license. | The surveyor's or accrediting organization's calendar, and the owner's readiness. | The same as an existing building: the surveyor's or accrediting organization's calendar. |
| Total First concept to first case. | State review and licensing add time before the first case in both columns. Usually the shorter path, with no site approvals. | Usually the longer path, mostly because of the site approvals before the permit. |
S&I builds to the state licensing requirements, coordinates inspections with the owner's team, and provides the required testing documentation before state licensing. The license and Medicare certification stay with the owner and the architect. For each step in order, see ASC construction and licensing steps in Texas.
What is usually not in the construction price
The construction price is not the cost of opening. Several items are usually bought outside the builder's base contract, and two contractors' numbers only compare if they treat these the same way. Ask each one for a written list of what is in and what is out.
- Equipment. Surgical lights and booms, tables, sterilizers and washers, scope reprocessors, imaging, and anesthesia equipment are normally bought by the center from its vendors. The construction price covers the structure, power, plumbing, and medical gas those items connect to. Settle in writing who installs each item.
- Phone and data cabling. Not typically in our base contract. We can provide it if you want one contract.
- Security, access control, call systems, and sound. Not typically in the base contract. We can provide them.
- Signage. Building and suite signs are not typically in the base contract. We can provide them. The landlord and the city both usually have sign rules.
- Furniture. Desks, seating, and other loose furniture are bought by the owner. S&I does not provide furniture.
- Design and other owner costs. Architect and engineer fees when you hire the architect directly, the licensing consultant, state application and accreditation fees, the physicist, computers and clinical software, and opening supplies. Ask whether permit fees and the independent testing reports are inside the contractor's number.
Add these to the construction number before you compare the total with your loan or your allowance.
How to get a first budget
You do not need drawings to start. S&I puts together a first budget at no charge. It is an early range, not an estimate, and it is meant to tell you whether a space or a site fits your budget before you commit to it. If you are considering a building, we will walk it with you before you lease or buy it, because its height, roof structure, and electrical service decide whether it can become a surgery center at a reasonable cost.
It helps if you can tell us:
- The building or site you are considering
- The specialties, and the number of operating or procedure rooms planned
- Whether a clinic will share the building
- Whether you have an architect, a licensing consultant, or equipment vendors yet
- When you need to be taking cases
A detailed estimate comes later, priced from the drawings as they develop. From the first concept we often schedule design, permitting, and construction together, so the calendar and the budget are worked out side by side. Call 817-329-4241 or send us a note.

Common questions
Why does a surgery center cost so much more to build than a medical office?
The mechanical, electrical, and medical gas systems are built and tested to health care standards. Operating rooms need far more air than an office, held at set pressure and humidity. The center also needs emergency power, fire-rated construction, piped medical gas, and structural support for lights and booms.
Why don't you publish cost per square foot?
Because costs move with materials, labor, and the specific building, a published range would soon be out of date or wrong for your project. Structures and Interiors gives each project a first budget at no charge, an early range built from your space or site and your plans. A detailed estimate is priced later from the drawings.
Is an endoscopy center less expensive to build than a surgery center?
Generally, yes. An endoscopy center is built around procedure rooms and scope reprocessing in place of operating rooms and full sterile processing, so the air, medical gas, and equipment support are lighter. It still follows the same Texas licensing path.
Can an existing office building be converted into a surgery center?
Sometimes. The building needs enough height above the ceiling for large ductwork, roof structure for air handling units, enough electrical service, and room outside for a generator and medical gas. A building without those can cost more to convert than a new shell costs to finish, so have it checked before you lease or buy.
Does the construction schedule include state licensing?
It should show it. The city's certificate of occupancy comes first, then the state's inspection and license, then a Medicare survey or accreditation. The owner's team leads licensing and certification. The builder's part is a building that matches the approved drawings and a complete set of test reports.
Is surgical equipment part of the construction contract?
Usually not. Lights, booms, tables, sterilizers, and imaging are normally bought by the center from its vendors. The construction contract covers the structure, power, plumbing, and medical gas the equipment connects to, so the vendors need to be chosen early enough to design around.
