A dental office build-out turns an empty or previously occupied space into a working practice. In Texas that means design, a city building permit, a state accessibility review, construction built around your equipment, and registration of your X-ray machines before you see patients. This guide walks through each part in the order you will meet it.
The steps, in order
Most dental build-outs follow the same sequence. The names change from one team to the next, but the order rarely does.
- Find the space and test it. Before the lease is signed, confirm the space can take the plumbing, power, and equipment a dental office needs.
- Choose the team. An architect or designer, an equipment supplier, and a general contractor. Some owners bring the contractor in early, while the design is underway (we call this design-assist).
- Plan the layout. Operatory count, sterilization, imaging, the mechanical room, and the path patients and staff take through the office.
- Complete the drawings. Architectural, mechanical, electrical, and plumbing drawings, coordinated with the equipment supplier's drawings.
- Permit and register. City building permit, plus the Texas accessibility registration and plan review described below.
- Build. Slab work and underground plumbing first, then walls, rough-ins, inspections, finishes, and cabinetry.
- Install equipment. Chairs, delivery units, compressor, vacuum, sterilizers, and imaging.
- Close out. Final city inspections, certificate of occupancy, accessibility inspection, and X-ray registration.
What makes dental different from an ordinary office
From the lobby a dental office looks like any professional suite. The difference is under the floor and inside the walls. Each operatory needs compressed air, vacuum, water, a drain, power, and data brought to an exact point at the chair. In most layouts those lines run under the slab, which means saw-cutting concrete in a lease space or placing sleeves before the slab is poured in a new building.
A mechanical room holds the air compressor, the vacuum pump, and usually an amalgam separator. A federal Environmental Protection Agency rule (40 CFR Part 441) requires most dental offices that place or remove amalgam to install a separator and file a one-time compliance report with the local wastewater authority. Some specialties that do not handle amalgam are exempt, so ask your equipment supplier how the rule applies to your practice.
If the office will pipe nitrous oxide and oxygen, that system is installed and tested under NFPA 99, the national health care facilities code. It needs a storage location for cylinders, zone valves, and alarms, and it should be decided early because the piping runs inside walls and above ceilings.
Sterilization is the other room that rewards early planning. Instruments should move one way, from dirty to clean, and the room needs the plumbing, power, and exhaust the sterilizers call for.
X-ray rooms and Texas registration
Intraoral units, panoramic units, and cone beam CT machines put different demands on the walls around them. Shielding for a given room should come from the equipment manufacturer's requirements or a shielding design by a qualified physicist. Do not rely on a rule of thumb, and do not assume the previous tenant's walls suit your machine.
In Texas, dental X-ray machines are registered with the Radiation Control Program of the Department of State Health Services (DSHS). The dental rule is in the Texas Administrative Code at 25 TAC 289.232. The practice must apply for registration within 30 days of first using the machine. Registration is the practice's responsibility. The builder's part is constructing the room to the shielding design and installing the blocking and power the machine needs.
Permits and reviews in Texas
Three reviews apply to nearly every dental build-out in the state.
- City building permit. Each city adopts its own edition of the building codes with local amendments, and each runs its own plan review and inspections. The fire marshal reviews fire alarm and sprinkler changes. The project ends with a certificate of occupancy.
- Texas accessibility review. The Texas Department of Licensing and Regulation (TDLR) administers the Texas Accessibility Standards (TAS). Projects with an estimated construction cost of $50,000 or more are registered with TDLR, reviewed by a registered accessibility specialist (RAS), and inspected by a RAS after completion. The plans go to the specialist within 20 business days after they are issued, and the inspection must be done within one year after construction is complete. Smaller projects still have to meet the Texas Accessibility Standards, but they do not have to be registered. Many cities ask for the TDLR project number with the permit application.
- Landlord approval. In a lease space the landlord usually reviews the drawings and sets rules for slab cutting, roof penetrations, and working hours.
Clearances at reception, restrooms, doors, and at least the required accessible treatment areas are where dental plans most often need adjusting.
What to decide before design starts
These decisions drive the drawings. Settling them early prevents most redesign.
- Number of operatories now, and how many to plumb for later
- Equipment supplier and delivery style (rear, side, or over-the-patient)
- Imaging: intraoral only, panoramic, or cone beam CT
- Piped nitrous oxide and oxygen, or portable
- Wet or dry vacuum, and where the mechanical room goes
- In-house lab, milling, or 3D printing
- Who supplies and installs cabinetry: millwork shop or equipment supplier
- Phone, data, and audiovisual needs at each chair
Where dental build-outs go wrong
Two sets of drawings describe the same rooms: the architect's and the equipment supplier's. When they disagree about a floor box, a wall-mounted X-ray arm, or a cabinet, the conflict has to be found on paper. Found in the field, it becomes a change and a delay. The three items that deserve a second check on every dental job are the under-slab utility locations, the solid blocking in walls for monitors and X-ray arms, and the electrical and data rough-in at each chair.
S&I checks the under-slab plumbing and the equipment rough-ins with the equipment supplier's installer before the slab is poured. We hold a second coordination review with the equipment supplier before drywall.
Cost and schedule
How long a dental build-out in Dallas–Fort Worth takes from permit to move-in depends on the amount of slab work and plumbing, the condition of the space, and equipment lead times. We do not publish a cost per square foot, because costs move with materials, labor, and the specific space. S&I prepares a first budget for your project at no charge, and a detailed estimate is priced later from the drawings. The items that move the cost most are the operatory count, the amount of slab work, piped gas, shielding, the condition of the existing space, the level of finish, and how much the landlord contributes. Our guide to dental office construction cost explains each one.
We build dental offices across North Texas. See our dental office construction page for more detail, or look at two completed offices: Golpa Dental Implant Center in Dallas and 21st Century Dental in Irving. We also build new dental buildings from the ground up, such as Wilson Orthodontics in Frisco. Our articles on building a new dental office from the ground up and converting second-generation office space into a dental office cover each path.
Common questions
Do I need a permit for a dental office build-out in Texas?
Yes. A dental build-out needs a building permit from the city where the office is located, and the work is inspected before a certificate of occupancy is issued. Most projects also go through the Texas accessibility review administered by TDLR.
Does a dental office have to register its X-ray machines in Texas?
Yes. Dental X-ray machines are registered with the Radiation Control Program of the Texas Department of State Health Services. Registration is the practice's responsibility. The contractor builds the room to the shielding design and the equipment installer sets the machine.
Can a dental office go into a space that was not built for one?
Often, yes. The questions to answer first are whether the slab can be cut for plumbing, whether there is enough electrical capacity, whether there is room for the compressor and vacuum, and whether the landlord allows the work. An early review by the contractor and equipment supplier is worth doing before the lease is signed.
When should I bring in the contractor?
Before the lease is signed if possible, and no later than early design. Early pricing shows what the space will cost to convert while the layout and the lease terms can still change.
Who coordinates with my dental equipment supplier?
The architect and the general contractor both do. The supplier's drawings set the exact locations of utilities at each chair, and the contractor's job is to make sure the under-slab plumbing, blocking, and electrical rough-in match them before the floor and walls are closed.
