How Do I Budget a Medical or Dental Office Buildout?

Where the money actually goes

Medical and dental builds are plumbing- and infrastructure-heavy, and the cost distribution looks nothing like a standard office fit-out. A generic office job spends most of its budget on carpet, drywall, and open-plan lighting. A dental or medical suite pours money into things a patient never sees — suction lines, air exchange, shielded walls. Understanding the breakdown lets you sanity-check a contractor's estimate line by line instead of trusting one blended per-square-foot number that hides where the real money sits.

Plumbing and operatories — roughly 20–35% of the build. Every dental operatory needs water, suction, drainage, and compressed air routed to the chair. Fully built and plumbed, each operatory runs about $25,000–$50,000. Exam rooms with sinks add supply and waste runs throughout the suite, and if the base building's plumbing stub-outs don't line up with your floor plan, you're cutting slab — an expensive, schedule-killing surprise.

MEP and HVAC — roughly 20–30%. Medical spaces require upgraded HVAC for air exchange, humidity control, and equipment heat rejection. Procedure and surgical rooms may demand dedicated air-handling units and negative-pressure isolation. Sterilization and imaging equipment throw off heat that standard rooftop units aren't sized for, so the tonnage on a medical suite frequently runs well above what the base building was designed to deliver.

Specialized infrastructure — roughly 10–25%. This is the medical-specific line most first-timers forget: lead shielding for X-ray and imaging rooms ($15,000–$60,000 depending on wall area and kV rating), medical gas lines (oxygen, nitrous oxide, vacuum), nurse-call systems, and shielded data cabling for imaging. None of it appears in an office build, and all of it must be designed in from the start rather than retrofitted.

Finishes and casework — roughly 15–20%. Medical-grade cleanable surfaces, seamless antimicrobial flooring, built-in cabinetry, sinks, and ADA-compliant clearances cost more per square foot than office-grade carpet and drywall. Sterility and durability requirements mean you're specifying materials rated for repeated chemical cleaning, not just what looks nice in a lobby.

Soft costs — roughly 10–15%. A healthcare-experienced architect, an MEP engineer, permits, and health-department or licensing review. Skimping here is a false economy; a generalist architect who's never drawn an operatory will cost you far more in change orders than the fee you saved hiring them.

FF&E and equipment — a separate budget entirely. Chairs, imaging (CBCT, panoramic X-ray), sterilization, and cabinetry are usually equipment-financed, not funded from the construction loan. Keep this line walled off from your build number or you'll blur two very different financing structures that lenders prefer to underwrite on their own terms.

Site selection: buy infrastructure, don't build it

The single largest lever on your budget isn't how you build — it's where you build. Leasing a space that already fits the medical use avoids the most expensive category of work entirely, and the decision you make before signing the lease outweighs almost every decision you make afterward.

Target a second-generation medical space. A former dental or medical office already has the operatory plumbing, shielding, medical-grade HVAC, and floor plan roughed in. Reusing that infrastructure can save $75,000–$300,000 and shave months off the timeline. Healthcare-advisory brokerage teams specialize in sourcing these "2nd-gen" medical suites, and the premium rent on a purpose-built medical office building (MOB) is usually cheaper than paying to convert a raw office shell into a licensable clinic.

Confirm core-and-shell capacity in writing before you sign. Medical uses demand far more water, drainage, electrical amperage, and HVAC tonnage than a standard office. Get the landlord to document available capacity in the lease. Discovering after signing that the building physically can't support your air-exchange rate or electrical load can add $50,000–$150,000 in service upgrades — or kill the deal outright while you're already on the hook for rent.

Check zoning, building classification, and parking. Not every office building permits medical use. Parking ratios (medical generates more visits per square foot than office), ADA access, and after-hours HVAC availability all matter to licensing. A cheap space that can't be licensed for patient care is worth nothing, so verify permitted use before you fall in love with a rate. A quick call to the municipal planning desk costs nothing and can eliminate a building from your shortlist before you spend money on it.

The TI allowance: medical tenants have leverage

Healthcare tenants are a landlord's favorite tenant — they sign long leases, carry strong credit, rarely leave once built in, and rely on infrastructure that's expensive to replicate elsewhere. That stickiness is negotiating leverage, and it directly funds your buildout. Treat the allowance as a number you win in negotiation, not one the landlord hands you.

Push for higher TI than retail or general office. A tenant-improvement allowance of $40–$100 per square foot is common for medical, and $100+/sq ft shows up for strong-credit groups or in purpose-built MOBs. On a 3,000-square-foot suite at $70/sq ft, the landlord funds $210,000 of your build — money you don't borrow and don't repay.

Demand free rent during the long build. Medical buildouts take four to eight months (longer for heavy infrastructure), and you shouldn't pay rent on a construction site. Negotiate six to twelve months of rent abatement — on a mid-size suite that's $30,000–$120,000 saved in cash you'd otherwise burn before seeing a single patient.

Ask for turnkey delivery on general medical. For non-specialized exam-room buildouts, some landlords will deliver the space built to your approved plans (a "turnkey" build), which shifts cost-overrun risk onto them. It's harder to get for surgical or operatory-heavy work where the risk is real, but always worth asking — the worst answer is no.

Understand that amortized TI is a loan. Any allowance above the landlord's baseline that gets "amortized" back into your rent is debt, typically at 7–10% interest. Before accepting an extra $30/sq ft folded into rent, compare it against an SBA 7(a) loan or equipment financing — you may borrow the same money cheaper elsewhere and keep your rent lower for the whole term.

Use a healthcare tenant rep. A broker who does medical leases knows which MOB landlords are active, what TI is trading at in your market, and how to structure the draw schedule. They're paid from the standard commission pool split with the listing side, not out of your pocket, so there's little reason to go unrepresented.

What the TI allowance quietly excludes

A $40–$100/sq ft allowance sounds like it covers the whole job. It usually doesn't — landlords typically fund hard costs only (framing, MEP, finishes), not the soft costs and equipment that make a medical office actually operate. Many first-time owners sign thinking the allowance covers everything and then discover they're personally funding 25–40% of the total.

Line items the TI allowance commonly excludes:

• Architectural and engineering fees: $5,000–$20,000 for a 3,000-square-foot space
• Permit and impact fees: $3,000–$10,000 depending on the municipality
• Equipment and furniture: $50,000–$200,000 for chairs, exam tables, imaging, cabinetry, and computers
• IT and low-voltage cabling: $5,000–$15,000 for structured data cabling and networking
• Moving and temporary operations: $10,000–$30,000 if you keep seeing patients elsewhere during construction

A concrete example makes the gap obvious. A dentist signs a 2,500-square-foot lease with a $60/sq ft allowance ($150,000). The buildout comes in at $250,000. The landlord pays $150,000; the dentist covers the remaining $100,000 in hard costs — plus roughly $80,000 in equipment and $5,000 in permits. Total out-of-pocket lands near $185,000, not the "$0, the landlord's paying" number they assumed at the signing table.

Two ways to close that gap. First, negotiate a turnkey allowance that explicitly includes soft costs and infrastructure upgrades, not just finishes — get the inclusions and exclusions listed in writing in the work letter, because a verbal "don't worry, it's covered" is worth nothing when the invoice arrives. Second, trade term for dollars: medical landlords prize long commitments, so offering a 10-year lease instead of 7 often unlocks another $10–$20/sq ft. You can also request that the landlord advance the allowance upfront rather than reimbursing after completion, so you aren't floating the whole build on a construction loan while you wait for draws to clear.

Control the build, the equipment, and the surprises

Once the lease terms are set, cost control shifts to how you contract and sequence the work. Medical construction has stricter inspections than commercial office — health department, infection control, and ADA all sign off — so the contractor and the plan discipline matter more than usual. Every failed inspection is both a fee and a delay, and delays on a leased space mean rent burning against zero revenue.

Get a fixed-price GC contract from a healthcare-experienced builder. A generalist contractor who's never passed an infection-control inspection will rack up rework and change orders. Fixed-price (rather than cost-plus) caps your exposure; healthcare experience means fewer failed inspections and fewer "we didn't know medical needed that" conversations mid-build.

Lock plans before bidding. Operatory plumbing and shielding are brutally expensive to move once framed — relocating a single operatory mid-build can cost $20,000+. Finalize the floor plan, equipment locations, and utility rough-ins before the GC prices the job, so you're not paying change-order premiums on decisions you could have made on paper for free.

Separate construction from equipment financing. Imaging, chairs, and sterilization equipment finance at favorable rates through equipment lenders or SBA programs. Don't bury a $150,000 CBCT scanner inside your construction loan where it's mixed with tenant improvements and harder to underwrite — and where you may end up paying construction-loan rates on gear that qualifies for cheaper equipment terms.

Carry a 10–20% contingency — non-negotiable. Medical retrofits routinely uncover plumbing, code, and HVAC surprises behind walls. On a $500,000 build, set aside $75,000–$100,000 for the predictable-but-unplaceable costs:

• Asbestos or mold remediation: $5,000–$30,000 if found in old tile, flooring, or ductwork
• Structural surprises: load-bearing walls that force a redesign, $10,000–$40,000 in added engineering
• Utility shortfalls: upgrading electrical service from 200 to 400 amps ($8,000–$20,000) or adding a water booster pump ($3,000–$8,000)
• Permit delays and re-inspection fees: $500–$2,000 per month when construction stalls

Phase the build if cash is tight. Complete the shell, plumbing, and electrical infrastructure first (often 60–70% of total cost), then finish operatories and exam rooms in waves as revenue arrives — build three operatories now, stub in plumbing and electrical for two more, and finish them in year two. Stubbing during the initial build is far cheaper than re-opening finished walls later. This requires a lease that permits future construction and a landlord open to phased TI draws, so negotiate that flexibility in from the start.

Don't get screwed: the traps that blow the budget

A handful of failure modes account for most medical-buildout budget blowups. Each one is avoidable with a pre-lease check, and every one of them costs multiples more to fix after signing than to catch before.

HVAC that can't carry medical load. Standard office HVAC won't meet medical air-exchange requirements. Verify tonnage and air-handling capacity before signing; discovering the shortfall after the fact costs $40,000–$100,000 to remedy, and there's no cheap way out once you own the lease.

Shielding and medical gas as afterthoughts. Lead shielding and med-gas lines must be designed in from the start. Retrofitting them after framing means demolishing finished work — pure rework you pay for twice, once to build and once to tear out and redo.

Health-department and licensing delays. Plan review, infection-control sign-off, and licensing inspections can add weeks to months. Hire a healthcare-experienced architect and, in slow jurisdictions, a permit expediter, so you're not paying rent on a space you legally can't open to patients.

TI clawbacks and draw expirations. Allowances often expire if unused within 6–12 months and can claw back on early default. Read the disbursement schedule and lien-waiver requirements before you sign — an allowance you can't actually draw is worth nothing on your balance sheet.

The cheapest insurance available: before signing the lease, pay a medical-specific MEP engineer $1,500–$3,000 for a pre-lease feasibility study. They'll confirm whether the existing plumbing, HVAC, and electrical can carry your program. That small spend routinely prevents $50,000+ in change orders — and a $1,000 attorney review of the TI clause can catch a $100,000 surprise buried in the work letter before it becomes your problem.

Related questions

Is it cheaper to renovate an existing medical suite or build from raw shell?

Renovating a second-generation medical space typically costs 20–40% less than converting raw office shell, because plumbing, medical gas, and specialized HVAC may already exist. The caveat: older suites sometimes need code upgrades that narrow the savings, so inspect the existing infrastructure before assuming the discount holds.

How long does a medical or dental buildout take?

Expect four to eight months from lease signing to certificate of occupancy for a straightforward buildout. Heavy-infrastructure projects — surgical suites, imaging, extensive operatories — can stretch to 10–14 months, with permit review and long-lead equipment delivery the most common causes of delay.

How much should I set aside for permits and design fees?

Permits plus architectural and engineering fees typically add 10–20% to the construction budget. This covers plan approval, structural and MEP review, and any zoning or health-department requirements, all of which vary significantly by city and by how heavily your build touches life-safety systems.

Should I fund equipment from my construction loan?

No — keep equipment financing separate. Imaging, chairs, and sterilization units finance at favorable rates through equipment lenders or SBA programs. Mixing a six-figure scanner into your construction loan complicates underwriting and blurs two different budgets that lenders prefer to evaluate on their own terms.

FAQ

What's the typical cost per square foot for a medical or dental buildout? Most general medical or dental offices land in the $100–$300 per square foot range. Simpler primary care or general dentistry sits on the lower end, while surgery, orthodontics, or imaging-heavy specialties push toward $200–$400+/sq ft. Location, existing infrastructure, and equipment requirements drive the final number more than anything else.

How much should I budget for permits and architectural fees? Permits plus architectural and engineering fees typically add 10–20% to your construction total. That covers plan approval, structural and MEP review, and zoning or health-department requirements. The range varies by municipality — jurisdictions with heavy plan-review backlogs cost both more in fees and more in carrying costs from delay.

What's the biggest hidden cost in a medical buildout? MEP work — medical gas systems, specialized HVAC for air exchange, and backup power — surprises owners most, often adding $30–$80 per square foot. Older buildings can require expensive upgrades to meet current ventilation and fire-suppression code, and those discoveries usually surface only after demolition opens the walls.

How much tenant-improvement allowance can I negotiate? Medical TI allowances commonly run $40–$100 per square foot, and strong-credit groups or purpose-built medical office buildings can push past $100/sq ft. It's highly negotiable: a longer lease term or creditworthy tenant secures more. Remember the allowance usually funds hard costs only, so confirm exactly what's included in writing.

How much free rent should I ask for during construction? Because medical buildouts take four to eight months, negotiate six to twelve months of rent abatement so you aren't paying for a construction site. On a mid-size suite that's $30,000–$120,000 in preserved cash — cash you'll want on hand for equipment and working capital before patient revenue begins.

Why do I need such a large contingency? Medical retrofits routinely uncover plumbing, structural, and code surprises behind walls, plus possible asbestos or mold in older buildings. A 15–20% contingency — $75,000–$100,000 on a $500,000 build — absorbs these without derailing the project. Never sign a construction contract without a written contingency line item.
