Opening a Dental Office in Chicago: The Technology Build-Out, From Lease to First Patient

You have signed a letter of intent on a never-occupied end-cap in a Naperville strip center, or you are touring a second-generation suite in Lincoln Park. The architect is drawing, and the contractor wants to know who your "data guy" is.

For the wider picture of running a practice here, start with our Chicago dental IT guide, and for ongoing dental IT support in Chicago once you open, Legend's city page has the details. This page stays with the build-out: the kind of space you have, when IT joins the drawings, what the building decides about cable and closets, when the internet carrier and ComEd come in, which devices to choose carefully, how charts arrive from a previous office, the milestones to opening day and the test to run before the first patient. For the national, place-free sequence, read the full new-office technology guide.

Is your Chicago-area space a shell, a second-generation suite or an existing practice?

The kind of space you lease sets the moment IT has to join the project and the surprises you will meet. A shell needs everything designed from scratch. A second-generation dental suite has cable and plumbing you must judge before reusing. An existing practice you buy brings systems, contracts and charts with it.

Most first-time owners describe their space by its rent and its parking. For the technology plan, describe it by what is already inside the walls. The three paths below are the ones startup dentists meet most often across Chicagoland, from a Loop tower to a new strip center in Aurora or Joliet, and each one moves the IT conversation to a different week.

If you are buying rather than building, the technology questions shift from construction to inheritance: what the seller's systems are worth, which contracts follow the sale and how the charts move. Our dental practice acquisition IT due-diligence checklist covers that path in detail, and the rest of this page assumes you are building or remodeling.

One more distinction is worth raising early. A space can look like a second-generation suite and still be a very different job. A former nail salon, bank branch or phone store is not a dental office, even with a ceiling full of old cable. Ask your architect how the project will be classified before you plan around any existing wiring, because that answer shapes the drawing set and therefore when the IT items are due.

When do IT and cabling need to be on the architect's drawings for a Chicago dental build-out?

Before the drawing set is final. Whatever path your architect chooses, the drawings your contractors build from should already show the network closet, its power and cooling, the cable route to each operatory, the carrier's entry point and the power for imaging equipment. Items added after that point arrive as changes, and changes cost time you did not plan for.

Inside city limits, the City of Chicago describes its Express Permit Program as a streamlined route for smaller nonstructural interior alterations, and its instructions list work in a space that has never been legally occupied, "such as the initial buildout of a 'shell' or 'vanilla box'", as not eligible for that program; your architect confirms which path applies.

In the suburbs, the conversation is the same with a different office. Naperville, Schaumburg, Oak Brook, Aurora, Joliet, Orland Park, Arlington Heights and every other village or city around Chicago has its own building department. If your lease is outside city limits, your architect is the right person to ask which department reviews the drawings and what it expects to see.

What matters for the technology schedule is the order of work, not the calendar. We do not publish permit durations or fees. We can tell you what the IT side owes the architect, and roughly when.

What the IT side owes the architect, by stage

A useful habit: every time the architect issues a revised set, check that the IT items survived the revision. Closets move, operatories get swapped, and a ceiling detail can change where cable is allowed to run.

What do buildings in the Loop, Oak Brook and Schaumburg decide about cabling, closets and risers?

The building decides more of your IT plan than any purchase does. A Loop tower controls its risers and telecom rooms, a Lincoln Park walk-up has tight walls and older wiring, and a Schaumburg strip-center end-cap gives you open ceilings but a long carrier path. Settle closet location, cable route and carrier entry with the landlord before the lease is final.

Have your electrician and low-voltage contractor agree the cabling method with each other and with the building before walls close. We do not state any conduit or cable-type rule here, because the method depends on your building, the landlord's standards and your contractors.

The table below is the one we wish every Chicagoland startup had before touring spaces. Use it as a list of questions to take into each walkthrough.

Three practical rules apply in every row.

1. 1. Wire every room where a computer, sensor, phone, printer or display will sit, including the sterilization area, the consult room and the lab. In a shell, it is cheaper to pull cable now than to open walls later. The room-by-room count belongs in your design work; our dental office design technology plan lays it out by room.
2. 1. Ask your equipment dealer for the electrical and data requirements of each imaging device before the electrician prices the job. Get those requirements in writing for each panoramic, cone-beam and intraoral unit, and make sure they reach the electrician before the electrical drawings are final.
3. 1. Choose the closet before you choose furniture. The next part of this page explains where to put it and why.

The network design itself, including switching, Wi-Fi coverage and separation of clinical and guest traffic, is a separate piece of work that follows the drawings; Legend describes that service on its network design page.

Where should the network closet go in a Chicago-area suite?

Put it inside the conditioned space, away from exterior walls, roof drains and plumbing stacks, with a door that locks. A Chicago winter can chill an outside wall, and summer storms test roofs and basements. If the only option is an outside wall or a basement, plan for heat, airflow and water before anything is mounted.

A closet is not a storage room with a switch in it. Before you accept a location, run through these points with the architect and the landlord:

• • Temperature. Is the room heated and cooled with the rest of the suite, or does it sit on a separate zone that the building turns down at night and on weekends? A closet on a setback schedule runs hot in July and cold in January.
• • Airflow. Equipment in a closed room needs somewhere for its heat to go. A louvered door, a return-air grille or a small exhaust fan is a drawing item, not an afterthought.
• • Water. Look up. A closet under a roof drain, a rooftop unit or an upstairs bathroom in a Lincoln Park walk-up is a closet that may one day get wet. In a basement, ask about water history before you choose it.
• • Power. A dedicated circuit for the closet, shown on the drawings, with battery units sized for a clean shutdown of the server or storage, the firewall and the switches.
• • Access. Who else has a key? In a medical office building in Oak Brook or Arlington Heights, the building may want access to shared telecom rooms; your own closet should stay yours.
• • Space to grow. Leave room on the rack and on the wall for one more switch, a second internet connection and any equipment a future operatory adds.

Our Chicago power and weather plan for dental offices covers what to put in that closet so the office rides through an outage and restarts in the right order.

When should the internet carrier and ComEd be on your schedule?

Put them on the schedule as soon as you have a signed lease and a suite address, because the carrier and the utility work to their own timelines, not yours. Ask each for the install or service date in writing, confirm what has to be ready inside the suite first, and decide early whether you want a second internet path.

We do not publish carrier or utility lead times. They change with the building, the street, the season and the provider's workload, and no number we could print would be reliable for your address. What we can give you is the list of questions that keeps the order of work straight.

Internet carrier questions

• • Which providers can serve this exact suite today, and which would need to build to it? Ask the landlord which carriers already reach the building, then confirm with each carrier by address.
• • What has to be ready inside the suite before the carrier will install: an open path from the building entry, power in the closet, a backboard, an escort from building management?
• • Can we get the install date in writing, and what happens to the date if construction slips?
• • Is a second, independent path possible, such as a second provider on a different medium, so a single cut cable does not close the office? Patients search a new practice by name and call it from the first day; the phones and the schedule both depend on the connection.
• • If the phones will run over the internet, when should numbers be ordered or moved so the published number works on the first day?

ComEd questions

ComEd describes itself as serving more than 4 million customers across northern Illinois, so for most suites from the Loop to Joliet it is the utility on the other end of the electrical work. Your electrician and general contractor usually manage the utility side of a build-out, but the IT plan depends on the answers.

• • Does the suite need a new or upgraded electrical service for the equipment you plan, or does the existing service cover it? Your electrician and architect answer this one.
• • Has the electrician placed a dedicated circuit for the network closet, and where are the circuits for imaging equipment?
• • Who is the contact for the utility work, and who will confirm the energize date in writing?
• • What will the office run on during a utility outage: battery units for the closet and front desk only, or more? That choice changes the closet's power and heat plan.

Which devices should you choose carefully for a new Chicago office?

Time clocks, door readers, workstation sign-in, cameras and phones are often chosen by whoever ships them, not by the practice. List each one before purchase, decide how staff will sign in and open doors, and keep the choice simple enough to support. Illinois has a biometric privacy law, so check with your attorney before buying fingerprint or face-scan devices.

These choices tend to arrive outside the IT plan. A payroll provider ships a time clock; a door-hardware installer offers a reader for the back door; a laptop arrives with face sign-in turned on; a camera system comes with analytics nobody asked for. Each one is easy to switch on and harder to unwind once staff rely on it. Making the list during the build-out, rather than after the boxes arrive, keeps the decisions with the owner.

Three habits keep this part of the build-out under control:

1. 1. One list, one owner. Keep a single device inventory with the make, model, location, who uses it and who supports it. The office manager owns the list; the IT provider keeps it current.
2. 1. Choose sign-in before you choose hardware. Whether staff sign in with a password and a second factor, a badge or a PIN changes which keyboards, readers and laptops you order.
3. 1. Ask every vendor who supports the device after opening. A time clock supported by the payroll company, a door reader supported by the locksmith and cameras supported by an installer you never see again make three phone calls on a bad morning.

The imaging rooms deserve their own list: sensors, intraoral cameras, the panoramic or cone-beam unit and the workstation that drives each one. Our guide to dental software and imaging support for Chicago practices covers how those systems are installed and kept working once patients are in the chair.

How do you bring patient records and images from a previous practice?

Agree first, with the office you are leaving, which charts and images will move. Then plan the format, the import and a test before opening. Practice management data and imaging files usually travel separately, so ask both vendors what they export and who runs any conversion. Keep records as long as your compliance advisor tells you.

If you are leaving an associate position, you are in common company. The American Dental Association's Health Policy Institute counted 23.5% of Illinois dentists up to ten years out of dental school as affiliated with a dental support organization in 2024, so the office you are leaving may be part of a group with its own policies and its own IT team. Whatever the setting, moving records has four practical parts.

1. What will arrive, and in what form? Records that arrive as exported files, image archives or paper copies each need a different plan. Patient images from sensors, panoramic units and cone-beam scanners are often stored by the imaging software rather than the practice management system, so ask what both export formats will be and whether the images stay linked to the right patient.

2. Who runs the conversion? Ask your software vendors early who converts data from one platform to another, what they need from you, and how long they want the files before go-live. Schedule the conversion before staff training, so people learn on real charts, not an empty system.

3. How will you check it? Pick a handful of patients and compare them line by line between the old export and the new system: demographics, treatment history, appointments, balances where they apply and images. A conversion that looks complete can still drop attachments or mismatch image links.

4. Where will charts and images live, and how are they backed up? Decide where data and images are stored, how they are backed up, how a retired computer's drive is wiped, and who can restore a chart from years ago. That makes the backup plan part of the build-out, not something to add after opening.

On the software side, choose the practice management and imaging platforms before you buy computers, because their requirements drive the hardware order and the server-or-cloud decision. Legend supports the IT environment of these practice management platforms: Dentrix, Eaglesoft, Open Dental, Archy. On the imaging side: DEXIS, Vatech, Carestream, Planmeca/Romexis, Dolphin Imaging. Our dental software migration checklist walks through the steps for moving data, images and schedules without losing production.

What does the run-up to opening look like for a new dental practice in Naperville, Aurora or Joliet?

Key the IT plan to construction milestones rather than calendar months: drawings, contracts, framing, rough-in inspection, drywall, ceiling grid, equipment set, carrier turn-up, staff training and the first patient. Each milestone has an IT task that becomes harder once the next one passes, and each task needs an owner named in writing.

The checklist below uses the order a Chicago-area build-out usually follows, whether the suite is in a Naperville strip center, an Aurora medical building or a Joliet storefront. Durations vary by building, permit path and contractor, so we give the sequence and the owner of each item, not a promised timeline.

Legend has worked on one of these openings in Chicago's northwest suburbs. Its project page for Little Roots Pediatric Dentistry records Legend's team on-site in Bartlett, Illinois, "installing and configuring technology as Dr. Marissa Dziepak's new practice approaches opening." That corresponds to the stretch of the checklist between equipment set and first patient, when the rooms are built and the technology turns into a working office.

What should the opening-day acceptance test cover in a Chicago office?

Run a written acceptance test in the last days before the first patient, with the office manager present and every result recorded. Cover the network, sign-ins, practice software, imaging, phones, printing, backups and a power and weather check, so the office learns its outage routine before a Chicago winter teaches it.

Use the list below as a starting point and add any check your software vendors require. Each line should end with a name and a pass or fail.

1. 1. Every workstation signs in with a named account, opens the practice management system and reaches today's schedule.
2. 1. Every operatory captures an image from its sensor or camera, and the image appears on another workstation in the same chart.
3. 1. The panoramic or cone-beam unit captures and saves a test image to the place the imaging software is meant to store it.
4. 1. Phones ring on the published number, transfer between rooms and reach voicemail; outbound calls show the right caller ID.
5. 1. Printing and scanning work at the front desk and in the consult room, including insurance cards to the chart.
6. 1. Wi-Fi covers the whole suite for staff devices, and guest Wi-Fi, if you offer it, is separate from the clinical network.
7. 1. A restore test passes: a file and a test chart record are restored from backup to prove the copy is usable, not merely present.
8. 1. The battery units are tested: unplug them for the closet and front desk and confirm the equipment shuts down cleanly, in the right order, with nothing left half-written.
9. 1. The closet's temperature is recorded with the door shut and all equipment running. If the closet sits on an outside wall, check it again on the first cold morning.
10. 1. A ComEd outage drill is walked through: who decides to close, how patients are called, how the schedule is reached from another location or a phone, and how the systems are restarted in order when power returns.
11. 1. Every device on the inventory list is set the way you decided: time clocks, door readers, workstation sign-in and camera features match the choices made during the build-out.
12. 1. The support number is on every desk, and every staff member knows how to report a problem.

The power and weather part of this test grows into a full routine after opening, and day-to-day support becomes the next decision. Our guide to managed IT for Chicago dental practices covers what to look for in support once the build-out crew has left.

What to ask your IT provider before you sign a lease in Chicago or the suburbs

Bring these questions to any IT provider you are considering, ideally while the lease is still being negotiated. The answers tell you whether the provider plans around Chicago buildings and the drawing schedule or just ships equipment.
