The Alithos planning model uses $170 per square foot for a standard leased build-out, $220 for premium, $340 for standard ground-up and $420 for premium ground-up construction in 2026. Cabinetry (10%) and soft costs (12%) add about 22%, so a standard leased build-out lands near $207 per sq ft all-in for construction. Equipment is separate. Published dental leasehold ranges run $150 to $350 per square foot.
"What does it cost per foot?" is the first question almost every dentist asks me about construction. It is a fair question with a slippery answer, because two quotes at the same per-foot number can cover very different work. Below are the rates I plan with, how they compare with published ranges, and how to tell whether a per-foot number in front of you is complete.
What does dental office construction cost per square foot?
The Alithos estimator assumes four construction rates. They are planning assumptions for a first budget, not quotes and not survey data. Cabinetry and soft costs (design, engineering, permits and similar fees) are modeled as 10% and 12% of construction, so the "all-in construction" column is the rate times 1.22.
| Project type | Construction rate | With cabinetry + soft costs |
|---|---|---|
| Leased space, standard finish | $170/sq ft | about $207/sq ft |
| Leased space, premium finish | $220/sq ft | about $268/sq ft |
| Ground-up, standard finish | $340/sq ft | about $415/sq ft |
| Ground-up, premium finish | $420/sq ft | about $512/sq ft |
Ground-up rates exclude land. The model's ranges are the point estimate plus or minus 5%.
How does that compare with the market? I know of no government survey of dental construction costs, so the best evidence available is published ranges from people who see a lot of projects:
| Source | What it measures | Published figure |
|---|---|---|
| Dental & Medical Counsel, 2026 [2] | Dental leasehold (tenant) build-out | $150–$350/sq ft |
| Dental & Medical Counsel, 2026 [2] | Dental ground-up construction | Often $400+/sq ft |
| JLL, 2026 [3] | Medical outpatient fit-out, all-in, from warm white box | $412/sq ft national average ($226 hard costs) |
| JLL, 2022 [4] | Same benchmark, earlier edition | $304/sq ft |
The model's leased rates of $170 to $220 sit inside the published dental leasehold range. Its ground-up rates are on the conservative side of the "often $400 or more" figure, so your market may run higher. The JLL number is medical outpatient space, not dental, and its "all-in" includes soft costs, furniture, fixtures, equipment and technology. Don't hold a contractor's dental hard-cost bid up against $412 and call it cheap.
What does that mean for a 3- to 10-op office?
A per-foot rate only matters once it is multiplied by the right number of feet. The estimator sizes space at 500 sq ft per operatory for 3 to 5 ops, 450 for 6 to 7, and 425 for 8 or more. Here is construction alone, before cabinetry, soft costs, equipment and land:
| Operatories | Sq ft | Lease standard ($170) | Lease premium ($220) | Ground-up standard ($340) | Ground-up premium ($420) |
|---|---|---|---|---|---|
| 3 | 1,500 | $255,000 | $330,000 | $510,000 | $630,000 |
| 4 | 2,000 | $340,000 | $440,000 | $680,000 | $840,000 |
| 5 | 2,500 | $425,000 | $550,000 | $850,000 | $1,050,000 |
| 6 | 2,700 | $459,000 | $594,000 | $918,000 | $1,134,000 |
| 7 | 3,150 | $535,500 | $693,000 | $1,071,000 | $1,323,000 |
| 8 | 3,400 | $578,000 | $748,000 | $1,156,000 | $1,428,000 |
| 9 | 3,825 | $650,250 | $841,500 | $1,300,500 | $1,606,500 |
| 10 | 4,250 | $722,500 | $935,000 | $1,445,000 | $1,785,000 |
Take a 5-op leased office at standard finish. Construction is $425,000. Cabinetry adds $42,500 and soft costs add $51,000, for $518,500. In the full model that project totals about $933,500, so construction and its related lines are a bit over half the budget. Equipment, imaging, IT, furniture and working capital make up the rest. The whole-project numbers for every row are in the Alithos cost benchmark.
The row you land on matters as much as the column. Sizing the office from production math, not from the space a broker happens to show you, is covered in how much space a dental office needs, and you can run it with the operatory square footage calculator.
Why does dental construction cost more per foot?
A general office is mostly open floor, a few walls and a restroom. A dental office packs utilities into almost every room.
- Plumbing density. Each operatory needs water supply, drains, vacuum and compressed air at the chair, usually run under the floor or in the walls. In an existing building that often means cutting and patching the slab.
- Mechanical room. The compressor and vacuum pump need their own room with ventilation and sound control, plus the piping that connects them to every chair.
- Imaging rooms. Pano and CBCT rooms may need shielding, which a qualified expert designs based on the equipment and the rooms around it [9].
- Electrical. Chairs, lights, sterilization equipment, imaging and IT all want dedicated circuits, and the service to the suite may need an upgrade.
- Sterilization and lab. These rooms need sinks, counters, dedicated circuits and ventilation.
- Accessibility. Patient restrooms, door widths, corridors and the front desk must meet federal accessibility standards [8] plus any state and local rules.
Each added operatory adds trades work, not only equipment. That is why cost per square foot stays high even as offices get bigger. The dental office build-out cost guide goes room by room.
What moves your number inside the range?
The existing space. This is the biggest lever on a leased project. A cold shell with no ceiling, no HVAC distribution and no plumbing means you are buying every wall and every pipe. A warm or "vanilla" shell gives you some of that. Second-generation dental space can save the most if its plumbing and mechanical room fit your layout. One contractor estimates second-generation medical space costs 30% to 50% less to build out [6], but that is a vendor claim, and the savings disappear if you move every wall. Get the space scoped before you sign the lease.
Region and timing. Labor and permit costs vary widely by market. JLL's 2026 benchmark notes that Northeast markets price higher than Sunbelt markets [3]. I don't apply a fixed regional percentage. I would rather see a local contractor's preliminary number early. Timing matters too: a quote is priced at a point in time, and long permit reviews add rent and carrying costs that no contractor bid includes.
Finish level. The gap between $170 and $220 in the model is mostly finishes and features: flooring, ceilings, lighting, glass, millwork and the look of patient areas. On a 2,500 sq ft office that $50 a foot is $125,000 of construction, and cabinetry and soft costs scale up with it.
Clinical scope. More operatories per foot, a CBCT room, surgical suites or a large lab push the rate up. JLL reports that moderate-acuity outpatient builds, such as those with expanded imaging, run about 10% above its baseline [5]. That is medical data, but the direction applies to dental.
Ground-up site work. A new building adds the structure, roof, site utilities, parking and landscaping. Those are inside the model's $340 to $420 rates. Land is not. The trade-offs between paths are in build, lease or condo and the guide to building a dental office.
What is in and out of a per-foot quote?
This is where most budget surprises come from. A contractor's per-foot number covers the contractor's scope. Everything else is yours to budget.
| Usually included | Often excluded (ask) |
|---|---|
| Framing, drywall, doors and ceilings | Architectural design fees |
| Plumbing rough-in and fixtures | Mechanical, electrical and plumbing engineering |
| HVAC distribution in the suite | Permit and plan-review fees, impact or utility fees |
| Electrical distribution and lighting | Clinical cabinetry and millwork (sometimes an allowance) |
| Flooring, paint and finishes to spec | Low-voltage cabling, IT, security and phones |
| General conditions, supervision and fee | Owner contingency |
| Contractor-side installation of in-wall utilities | Equipment install coordination, imaging shielding design, signage |
Every quote draws this line differently. Read the exclusions and assumptions page before you read the price. The longer list of lines owners forget is in hidden costs that ambush dental office projects.
Per-foot math only works if everyone uses the same feet. A lease may quote rentable square feet, which includes a share of common areas, while a contractor prices the usable suite. A lower per-foot number on more feet can be the same total. Compare totals.
How have construction prices changed?
The Bureau of Labor Statistics tracks the prices of goods that go into nonresidential construction, such as metals, lumber, concrete, fuel and equipment. Its index of net inputs to nonresidential construction (goods) stood at 184.9 in September 2026, up about 11.2% from 166.3 in September 2025 and 2.3% from August 2026 [7]. It is about 59% above its January 2020 level of 116.2. Recent months are preliminary and BLS revises them [10].
Two cautions. The index measures materials and other goods, not labor or the price a contractor bids. And published benchmarks move with it: JLL's medical outpatient figure went from $304 in 2022 to $412 in 2026, though the scopes of the two editions may differ [3][4]. The practical point is simple. Ask how long a quote's pricing holds, and don't build next year's project on a per-foot number from two years ago.
How do you compare bids per foot?
- Same drawings. Every bidder prices the same plan set and revision. A bid on an older set is a different project.
- Same scope sheet. List each scope item, then mark included, excluded or allowance for every bid. Gaps become obvious in one view.
- Separate allowances. An allowance is a placeholder, not a price. A low allowance for cabinetry or lighting makes a bid look cheaper until the real number arrives as a change order.
- Same square footage. Divide every total by the same usable square footage before you compare per-foot figures.
- Compare totals and terms. Look at contingency, schedule, exclusions and how change orders are priced, not only the headline rate.
How the contract is structured changes what you can compare. A design-build firm may give one number early, while a design-bid-build process lets several contractors price finished drawings. The trade-offs are in design-build vs design-bid-build.
This is the kind of work I do as an independent quote review. I'm not a contractor, architect or engineer, and I don't take commissions or referral fees from anyone in the project. I put the quotes side by side against the budget and show you where they differ. The Budget Plan ($7,500 to $10,000 flat fee, scope in writing) sets the construction budget before you sign a lease. Project Navigator (from $20,000, quoted per project) adds owner-side advisory through opening, including quote and change-order review. Availability depends on your project's state, and I confirm it before we engage.
How do you turn a per-foot rate into a project budget?
- Size the space. Start from operatories and production, not from a listing.
- Pick the rate. Leased or ground-up, standard or premium. Check it against a local contractor's preliminary number as early as you can.
- Add about 22%. Cabinetry at 10% and soft costs at 12% of construction, in the model.
- Subtract what the landlord pays. A tenant improvement allowance offsets part of a leased build-out. See negotiating a TI allowance and the TI allowance calculator.
- Add everything that isn't construction. Equipment, imaging, IT, furniture and working capital. The startup costs guide lists each line.
The cost estimator runs steps 1, 2, 3 and 5 with these same model rates. It does not subtract a TI allowance, so take that off its construction line yourself.
Frequently asked questions
What is the average cost per square foot to build out a dental office?
I know of no reliable national average for dental build-outs. A 2026 dental-lawyer guide publishes a range of $150 to $350 per square foot for a leasehold build-out. The Alithos planning model uses $170 per square foot for standard finish and $220 for premium, before cabinetry and soft costs, which add about 22%.
Why is dental construction more expensive than a regular office?
Every operatory needs water, drains, vacuum, compressed air and dedicated power at the chair. The office also needs a mechanical room for the compressor and vacuum, a sterilization room, imaging rooms that may need shielding, and more ventilation and electrical capacity than a typical office suite.
Does cost per square foot include dental equipment?
Usually not. Contractor per-foot pricing covers construction. Chairs, delivery units, lights, sterilization equipment and imaging are budgeted separately. The Alithos model uses $42,000 per operatory for standard equipment and $58,000 for premium, plus $60,000 for sensors and a pano or $130,000 with CBCT.
What does it cost per square foot to build a dental office from the ground up?
The Alithos model plans ground-up construction at $340 per square foot for standard finish and $420 for premium, before cabinetry, soft costs and land. A 2026 dental-lawyer guide says ground-up often runs $400 or more per square foot, so the model sits on the conservative side and your market may run higher.
Is second-generation dental space cheaper per square foot?
Often, if the existing plumbing, mechanical room and layout fit your plan. One contractor estimates second-generation medical space can cost 30% to 50% less to build out. The savings shrink fast if walls move, the plumbing is in the wrong place or the equipment is past its useful life, so get it scoped before you sign the lease.
How do I compare contractor quotes per square foot?
Put every bid on the same drawings, the same scope sheet and the same square footage. List what each one includes and excludes, separate allowances from fixed prices, and compare the total, not the per-foot headline. An independent quote review catches the gaps before you sign.
