What a dental practice in Plano, Frisco, McKinney, or Allen actually costs to build right now — the real per-SF bands, the three line items that move the number most, and a value-engineering example from KVC Pediatric Dentistry.
All cost figures are directional planning ranges, researched May 2026, subject to final preconstruction review. They are feasibility numbers, not bids. Pereff is not a lender. [DFW cost benchmarks, 2026; Pereff medical/dental vertical knowledge base, 2026]
Collin County is one of the densest, fastest-growing dental markets in the country. Plano, Frisco, McKinney, Allen, and Prosper have added rooftops faster than they've added operatories, and the doctors who call us are trying to answer one question before they hire an architect: what is a realistic build-out number for a practice in this market? The honest answer is a range, and it's wide for a reason — a four-operatory general-practice finish-out and a six-operatory practice with cone-beam imaging are not the same project, even at the same square footage. Below are the per-SF bands we actually see in 2026, the three line items that decide where your project lands inside them, and a real value-engineering example. Use these to test feasibility and size a loan request — not to negotiate a bid.
The per-SF bands for a Collin County dental build-out
Medical and dental tenant improvements across the DFW suburbs run roughly $175–$450 per square foot for construction, directional. That full range is honest but not very useful on its own. Broken down by practice complexity, it gets actionable:
$175–$225/SF
Basic dental finish-out (3–4 operatories, no dedicated imaging room), directional, May 2026 [DFW cost benchmarks, 2026]
$225–$300/SF
Mid-complexity dental (4–6 operatories, one pan/perio or X-ray room), directional, May 2026 [DFW cost benchmarks, 2026]
$300–$450/SF
Specialty dental with imaging suite (cone-beam CT, surgical scope), directional, May 2026 [DFW cost benchmarks, 2026]
Worked example: a 5,000 SF mid-complexity dental practice in Plano commonly runs $1.0M–$1.4M all-in for construction, directional. A leaner 3,000 SF general-practice finish-out can land closer to $525K–$675K. A 6,000 SF practice with a cone-beam suite and a surgical operatory can push past $1.8M before equipment. These are the numbers to take to your CPA and your banker for feasibility — they are not a quote.
DFW commercial construction costs rose roughly 12–18% from 2023 to 2026, with growth slowing to about 3–4% in 2026. The practical implication: lock material orders and long-lead equipment early, because waiting in an inflationary market quietly raises your number. [construction cost trend data, 2026]
One Collin County factor protects your budget: permitting is genuinely fast. Suburban jurisdictions typically review standard commercial permits in about 3–8 weeks, well under the 6–12 weeks Dallas proper can take — a shorter loan-carry period and less schedule risk even when hard costs are firm. The flip side is high subcontractor demand: the same trades that build medical office shells, ground-up retail, and apartments compete for crews, which keeps Plano, Frisco, and McKinney labor pricing firm. [permitting timeline data, 2026; DFW cost benchmarks, 2026]
The most expensive Collin County surprise is the shell you didn't inspect. A second-generation space can come with slab plumbing rough-in that doesn't match your operatory layout — forcing saw-cutting. A raw vanilla shell can come with a landlord work letter that excludes the MEP capacity your practice needs. Confirm what's in the slab and the shell before you sign the lease, not after.
The three biggest cost drivers
1. Operatory plumbing density
Each operatory is its own small mechanical system: water supply, vacuum line, compressed air, and a drain — repeated at every chair position. A six-operatory practice carries dramatically more rough-in than a three-op suite, and the cost compounds when the existing slab plumbing doesn't line up with your layout and the crew has to saw-cut and re-pour. Operatory count is the single biggest variable in most general-practice budgets. Before anyone quotes you, count your chairs and confirm whether you're in a finish-out space with usable slab rough-in or a raw shell that needs everything routed from scratch. [Pereff medical/dental vertical knowledge base, 2026]
2. Lead-lined CBCT and imaging shielding
A lead-lined room for cone-beam CT (CBCT), panoramic, or X-ray is the single largest cost driver by order of magnitude when it's in scope. Shielding is not just a materials line — it carries a separate radiation shielding report, structural coordination (sometimes slab or framing modifications to carry the lead and the equipment), and an added layer of city plan review. A single shielded imaging room can add roughly $40K–$100K-plus depending on the modality and room size, directional. If your practice plan includes CBCT, budget toward the top of that range and commission the shielding design early in design development — discovering it during construction is exactly how a fixed budget breaks. [Pereff medical/dental vertical knowledge base, 2026]
3. Casework and millwork
Dental casework is deceptively expensive. Sterilization-center millwork, operatory cabinetry, lab benches, and reception built-ins are specialty items, and the finish level you choose moves the number meaningfully. Stock laminate casework sits at the bottom of the band; custom solid-surface, specialty stainless lab cabinetry, and high-end reception millwork sit at the top. This is also where vendor lead times bite — specialty stainless dental lab cabinets can carry multi-month lead times that threaten your open date. Pereff has fabricated stainless-steel dental lab cabinetry in-house when a vendor quoted a six-month lead time, building it in roughly two weeks at about a third of the vendor's cost — a capability that is rare in this market and that protects both budget and schedule.

A value-engineering example: KVC Pediatric Dentistry
KVC Pediatric Dentistry — Dr. Velasquez and Dr. Chen — needed a 3,000 SF pediatric dental office in Little Elm, just over the Collin County line in Denton County. Before they reached Pereff, they had hired an expensive dental consultant who was struggling to assemble a competitively priced architect and a builder who could move. The project was stalling. Pereff replaced the consultant entirely under its One Source Solution at no separate fee, value-engineered the design to the doctors' bank-approved budget, and delivered the project at $423,000 — roughly $141/SF — complete in three months.
The KVC figure of ~$141/SF sits below the typical Collin County band, and that's the point worth understanding. It was achievable because the scope was tightly defined at the design stage — a pediatric program with no cone-beam suite, a modest operatory count, and value-engineered casework — not because the market price dropped. The lesson isn't 'expect $141/SF.' It's that true design-build finds the budget-meeting configuration before you sign a construction contract, not through change orders after.

What the per-SF number leaves out
The bands above cover hard construction costs. Three categories sit on top, together adding 25–45% to total project cost — and the most common feasibility mistake we see is a doctor who sized a loan against the construction number alone:
- Soft costs — design, permits, engineering, inspections, financing carry, insurance — typically 15–30% of hard costs.
- FF&E and dental equipment — chairs, imaging units (CBCT/pan), sterilizers, operatory delivery systems — often $200K–$500K for a mid-size practice, budgeted separately from construction.
- Contingency — plan 8–12% on a new dental finish-out; more if you're renovating an occupied space or the shell carries unknown conditions.
A Collin County dental project that pencils at $1.1M in hard construction costs can land at $1.6M–$1.8M all-in once soft costs, FF&E, and contingency are counted. Size your loan request against the all-in number — that's the number your bank underwrites and the number that determines whether your practice opens on plan.
Start with a directional range, then design to it
If you're weighing a build in Plano, Frisco, McKinney, Allen, or Prosper, start with a range rather than three bids. Five answers move a Collin County dental project within 10–15% of where preconstruction will confirm it: practice type, operatory count, imaging modality, ground-up versus finish-out (and the slab condition if it's a finish-out), and target open date. With those, we can hand you a directional range you can take to the bank for feasibility — not a fake-low square-foot teaser that turns into change orders once you've signed. That's the difference between a number you can plan around and one designed to win a contract.
