If you're working out how to build a dental office in 2026, plan on 6–9 months from planning to opening for a leasehold build-out and 9–18 months ground-up (Dental & Medical Counsel). One national lender sees startup totals average about $1 million (Bank of America Practice Solutions). This hub links every budget, lease, timeline and financing guide.

What is FloorStack? FloorStack is the dental build-out platform where doctors, contractors, architects, equipment reps and IT teams plan, build and document a dental practice together in live 3D, and the doctor owns every device, password and record when the doors open.

Who this hub is for

Doctors planning a first practice: start with the 12-phase roadmap, then price the project with the startup cost and per-square-foot guides before you tour spaces.
Associates weighing their options: read the startup-versus-acquisition comparison first; if buying looks better, jump to the Dental Practice Appraisal hub.
Startup consultants: use the master checklist and the lease negotiation checklist as client-facing templates.
DSO development teams: start with the de novo checklist, which turns site-to-opening into one repeatable template.
Contractors, architects, equipment reps and IT teams: skim the timeline and lender guides so your bids and schedules match what the doctor and the bank expect.

The build-out path in order

Most dental startups move through the same sequence, and each step in this hub links to the guide that covers it in depth:

Decide the path. Choose between a startup and an acquisition, and between leasing and buying real estate.
Set the budget. Price construction per square foot, equipment, technology, soft costs and working capital, and leave a contingency of 10–15% of construction (Dental & Medical Counsel).
Find and negotiate the space. Inspect second-generation suites, ask the landlord the right questions, and negotiate the tenant improvement allowance and work letter.
Line up financing. Give the lender a budget and schedule it can underwrite.
Design, permit and build. Hand off to the Dental Office Design hub and the Dental Office Construction hub.
Equip, wire and open. Order long-lead equipment early, since chairs, delivery units, cabinetry and imaging take 14–24 weeks from order to install (Curve Dental), then finish IT and credentialing.

Free tools for this hub

Start with the Build-out cost & timeline calculator

The Build-out cost & timeline calculator (free tool, coming soon) is the anchor tool for this hub. It is planned to estimate your budget and schedule from square footage, operatory count and region, so you can compare a quote or a lender's projection against published ranges such as $150–$350 per square foot for a California tenant build-out (Dental & Medical Counsel). Until it launches, use the cost and timeline guides above.

Other free tools for this stage

FloorStack Studio (live, free plan): a 3D IT plan of your office with every device placed.
Dream-practice builder (free tool, coming soon): sketch rooms, operatory counts and layouts on your own suite before you pay for drawings.
Permit & inspection tracker (free tool, coming soon): track every permit, inspection and sign-off through the certificate of occupancy.
Network & IT plan generator (free tool, coming soon): turn your floor plan into a drops, rack, Wi-Fi and VLAN plan.
Credential ownership checklist (free tool, coming soon): list every admin account the practice should own, with a "password hostage" letter template.
Equipment inventory & appraisal report (free tool, coming soon): build an equipment inventory with warranties and an appraisal-ready report.

How FloorStack helps

FloorStack is built so that the budget, lease, schedule and drawings for a startup live in one shared project instead of in separate inboxes. The planned shared project room is intended to give your consultant, architect, contractor, equipment dealer, IT provider and lender one schedule and one document set. FloorStack Studio is live today on a free plan. You upload a floor plan or a phone photo, and in about 10 minutes it returns an interactive view with every device placed, a device schedule with rooms, ports and cable lengths, and a rack layout; it is vendor-neutral, suggests up to 3 alternatives per device and never asks for patient data (FloorStack FAQ).

Frequently asked questions

How long does it take to build a dental office?

About 6–9 months from planning to opening for a leasehold build-out and 9–18 months for a ground-up building (Dental & Medical Counsel). Lease execution to certificate of occupancy runs about 5–9 months (Curve Dental). See how long a build-out takes.

How much does it cost to build a dental office?

Tenant build-outs in California run about $150–$350 per square foot and ground-up construction $400+ (Dental & Medical Counsel). One national lender sees total startups at $950K–$1.05M (Bank of America). See the build-out cost guide and the startup cost guide.

Should I start a practice from scratch or buy one?

It depends on your market, your production and your appetite for risk. The startup versus acquisition comparison walks through the five-year math, and the Dental Practice Appraisal hub covers what to check if you buy.

How much working capital does a dental startup need?

Lenders commonly plan about $100,000, often more, covering 6–9 months of expenses (Bank of America; Panacea Financial). See dental startup working capital.

What should I negotiate in a dental lease?

Start with the tenant improvement allowance, the work letter and the exclusive-use, relocation and assignment clauses. Typical medical TI runs $40–$100 per square foot nationally (MedWest Realty). See the TI allowance guide and the lease negotiation checklist.

When should I order equipment and start credentialing?

Early. Major equipment takes 14–24 weeks from order to install, and insurance credentialing takes 90–180 days after submission (Curve Dental). The 12-phase roadmap shows where both fit.

Do I need a dental startup consultant?

Not always. The consultant cost guide explains what they do and how they charge, and the consultant master checklist shows the work you would otherwise run yourself.
