What’s the average TI allowance per square foot for medical office space in 2027

What a medical buildout actually looks like from LOI to occupancy

The reason no honest broker quotes you a flat "average" number per square foot is that the allowance is an output of a process, not an input to it. It gets set — or should get set — after somebody prices real drawings. Most tenants do it backwards: they sign a letter of intent with a number the landlord proposed, then discover during design development that the number covers maybe half of what the space needs.

The correct sequence runs roughly like this. First, programming: a healthcare architect sits with the practice and counts rooms. How many exam rooms, how many providers per room, is there a lab draw station, a procedure room, a sterilization corridor, on-site imaging. This produces a room-by-room program and a rough square footage target. Primary care commonly programs around 1,200–1,600 square feet per provider once you include waiting, reception, staff areas, and circulation; specialties with equipment rooms program higher.

Second, test fit. The architect drops that program into the specific shell you're considering. This is where most deals reveal their real cost. A shell with column spacing that fights your exam-room module, a floor plate too deep for daylight, an existing restroom core in the wrong corner, or a slab that can't take the point load of imaging equipment — each of these adds cost that the landlord's generic allowance never contemplated. Two spaces at identical asking rent can differ by a large multiple in buildout cost purely because of shell geometry.

Third, schematic pricing. A general contractor prices the test fit at a conceptual level. This number is deliberately rough — usually presented as a range with a stated contingency — but it's the first honest signal of whether the offered allowance is close. If the landlord offered an allowance and the schematic price is double it, you now have a negotiating fact rather than a feeling.

Fourth, lease and work letter negotiation happen in parallel with design development, not after. The work letter is the exhibit that defines who builds what, to what standard, on whose money, by when. It is the single most consequential document in the transaction and the one most often signed as boilerplate.

Fifth, permitting. Medical projects frequently trigger plan review by both the local building department and, depending on the state and the use, a health-facilities licensing authority. Ambulatory surgery and anything requiring licensure can add months. Permitting is a schedule risk that converts directly into a cost risk, because rent commencement clauses often start ticking on a fixed date regardless of whether the permit landed.

Sixth, construction, commissioning, and inspection. Medical spaces require testing that ordinary commercial offices don't: air balance reports for pressure-controlled rooms, medical gas certification if you have piped oxygen or vacuum, radiation shielding surveys by a physicist for imaging rooms, and backflow prevention certification. Each of these is a document, a fee, and a scheduling dependency.

Who actually holds the pen: landlord, tenant, GC, and architect

TI money moves through four parties, and the allowance you end up with depends heavily on which of them controls the contract.

The landlord is underwriting a return. Their allowance is not generosity — it is capital deployed against a lease's net present value. A landlord will nearly always spend more per square foot on a tenant signing ten years than five, and more on a credit tenant (a hospital system, a large physician group, a national urgent care brand) than on a two-physician startup practice with no operating history. This is why the "average" question misleads: the same landlord, in the same building, will offer materially different allowances to two medical tenants in the same week. Landlords also care about generic reuse value. Exam rooms and a reception desk have residual value for the next medical tenant. A shielded MRI vault, a sterile core, or a lead-lined mammography room does not, and landlords discount their contribution to hyper-specialized work accordingly.

The tenant — the practice — is usually the least experienced party at the table and the one bearing the most risk. Most physicians negotiate a lease a handful of times in a career. The landlord's asset manager does it monthly. This asymmetry is the single strongest argument for a tenant-representation broker who specializes in medical, whose fee in most markets is paid out of the landlord's commission pool.

The general contractor is where the allowance meets reality. There are two dominant delivery structures and they change the economics. Under a landlord-built deal, the landlord's contractor builds to the approved plans and the landlord manages the job; the tenant gets less control, often pays a landlord construction-management fee (commonly a few percent of hard costs), and has weak leverage on change orders. Under a tenant-built deal, the tenant hires the GC and the landlord reimburses against the allowance on a draw schedule. Tenant-built gives you control and competitive bidding, but you carry the cash float and the schedule risk, and you'll be asked for lien waivers before each draw is released.

The architect and engineers determine whether the number is real. A generic commercial architect can lay out an office; a healthcare architect knows that a sink location dictates a plumbing chase, that the state's licensing rules may specify minimum clear dimensions in an exam room, and that infection-control standards drive finish selection. Retaining the wrong designer is a false economy that surfaces during plan review, when the correction cycle costs weeks.

Two more parties matter in medical deals specifically. Equipment vendors must be looped in early, because imaging and sterilization gear come with utility, ventilation, and structural requirements that must be in the construction documents, not discovered afterward. And in hospital-affiliated buildings, the health system's real estate group may impose its own design standards on top of the landlord's, which functionally raises the buildout cost floor.

Real cost ranges, contingencies, and how the gap gets funded

Instead of chasing a single average, model the spread. Medical buildouts stratify cleanly by clinical intensity, and the reliable pattern across markets in 2027 is this ordering, from lowest to highest total cost per square foot:

Second-generation medical space — a suite previously built as a clinic, being re-tenanted by a similar specialty — is the cheapest path by a wide margin. You inherit exam-room walls, plumbing chases, and a code-compliant egress layout. Work is often cosmetic plus selective MEP modification. Many tenants can execute here inside a landlord's standard allowance.

Primary care, behavioral health, and general practice in a warm shell sits next. Exam rooms, a nurse station, a small lab draw area, standard HVAC zoning, no shielding, minimal special power. Costs are meaningfully above conventional office because of the sheer count of small rooms with plumbing and doors, but the delta is contained.

Dental, dermatology, ophthalmology, and physical therapy climb from there. Dental in particular is plumbing-heavy — each operatory needs water, drain, air, and vacuum, plus a central compressor and vacuum room — and it needs intraoral or panoramic radiography shielding. PT is a different shape: less MEP, more open floor, but heavy-duty flooring, higher ceiling clearance, and sometimes structural attention for equipment and hydrotherapy.

Diagnostic imaging is a step change. Lead or barium shielding, physicist-designed and physicist-verified. RF shielding for MRI. Slab reinforcement or slab-on-grade siting for magnet weight. Dedicated electrical service, sometimes a separate transformer. Chilled water or dedicated cooling for the magnet room. Quench venting to the exterior. Any single one of these can exceed the entire allowance on a small suite.

Ambulatory surgery and procedure suites top the range: sterile processing, air-change-rate-driven ventilation with pressure relationships between rooms, medical gas piping and manifolds, emergency power to the essential electrical system, and licensure-driven room dimensions. This is the tier where a warm shell simply cannot be done inside any customary allowance.

On contingency: carry it deliberately, in three layers. A design contingency during early pricing, because drawings aren't done. A construction contingency in the GC's contract for field conditions. And an owner's contingency the tenant controls, which is the only one available for scope you decide you want mid-job. Existing-building projects deserve a fatter contingency than new shells — hidden conditions above the ceiling and inside walls are the norm, not the exception, in older commercial buildings.

Then there are the costs the allowance usually excludes. Read the work letter for what's carved out: architectural and engineering fees, permit and plan-review fees, the landlord's construction management fee, low-voltage cabling, security and access control, signage, furniture, medical equipment, IT hardware, moving, and — critically — the physicist's shielding design and post-installation survey. It's common for a tenant to discover the allowance is "hard costs only" after budgeting as though it covered everything.

When the allowance falls short, three funding structures dominate. Over-allowance amortization: the landlord funds the excess and you repay it inside rent over the term, typically at a stated interest rate. Negotiate that rate — it is a loan, and the first rate offered is rarely the best available. Turnkey: the landlord delivers a finished suite to an agreed specification and prices it into base rent. Simple, capital-light, and you give up control over means, methods, and finish selection unless the specification is exhaustively documented. Direct tenant capital, sometimes via an equipment or practice-finance lender; this preserves the lowest ongoing rent but consumes working capital at exactly the moment a new location has no revenue.

One structure worth knowing from the broader commercial world: for a growing practice signing multiple sites, some landlords and developers will treat the buildout as a build-to-suit and roll cost into a longer-term rent structure across locations. It's more common in freestanding retail-adjacent medical — urgent care, dialysis, veterinary — than in multi-tenant medical office buildings, but it's the same underlying trade: capital today for rent tomorrow.

Where commercial medical deals go wrong

The failures repeat with remarkable consistency, and nearly all of them are avoidable at the LOI stage.

Signing the LOI before a test fit. The LOI fixes rent, term, and allowance. Once those are set, the tenant's leverage collapses. Doing a test fit and a schematic price before the LOI costs a modest professional fee and is the highest-return spend in the entire transaction.

Treating the work letter as boilerplate. The work letter should specify delivery condition of the shell in detail (is the HVAC main trunk installed? is the sprinkler main distributed? is the floor level to a stated tolerance? is the electrical service sized and where does it terminate?), define base building versus tenant work, state the allowance and what it may be spent on, set the draw and reimbursement mechanics, define approval turnaround times for both parties, and address what happens to unused allowance. Vague delivery language is how a "warm shell" becomes a cold shell at the tenant's expense.

Missing the rent commencement trap. If rent starts on a fixed calendar date but the landlord's approvals, or a landlord-caused delay, push construction, you pay rent on a space you can't occupy. The fix is a tenant delay / landlord delay clause with day-for-day abatement for landlord-caused delay, and a rent commencement tied to the earlier of substantial completion plus a fixture period or a long-stop date.

Ignoring the permit and licensure calendar. Health-facility licensing review, certificate-of-need requirements in states that have them, and medical gas certification all sit on the critical path. Build the schedule backward from the date the practice must open and add float.

Skipping environmental and structural due diligence. Older commercial buildings carry asbestos-containing materials in floor tile and mastic, lead paint, and occasionally prior-tenant contamination. Abatement is expensive, schedule-destroying, and rarely inside the allowance. Make the lease contingent on satisfactory Phase I results and, where imaging is planned, on a structural engineer's confirmation of floor capacity.

Underestimating power and cooling. Practices consistently discover that the building's electrical service, or their pro-rata share of it, can't support their equipment plan. Confirm available amperage at the panel and available tonnage — or the right to add a dedicated unit and where it can be located — before signing. Rooftop space and structural capacity for supplemental units are finite in multi-tenant buildings and are allocated first-come.

Forgetting the exit. Restoration and removal obligations at lease end can be brutal in medical space. If the lease requires you to remove all tenant improvements and restore to shell, you may be liable to demolish the very buildout you partly paid for — including shielding. Negotiate the removal obligation down to specified items, agreed in writing at the time of approval, not judged years later.

No expansion path. Practices grow. Negotiate a right of first offer or first refusal on contiguous space, and pre-agree the allowance treatment for expansion space so you aren't renegotiating from scratch under time pressure.

A negotiation checklist you can run before signing

Work this list in order. Each step either improves the allowance or reduces the cost the allowance must cover — both move the same number.

Establish the true cost first. Program, test fit, schematic price. Bring a number, not an aspiration. Landlords respond to documented scope; they discount vague requests.

Benchmark locally, not nationally. Ask a medical-specialty tenant rep for recent comparable work letters in your submarket — same building class, same clinical intensity, same term. Local comps beat any published national average, because allowances track submarket vacancy and landlord capital position more than they track national construction indices.

Trade term for capital, deliberately. A longer term is the tenant's most valuable currency. Price what an extra three years is worth to the landlord in allowance dollars and decide whether the practice's business plan supports it. Pair a longer term with an early-termination right or a contraction option so the flexibility loss is bounded.

Negotiate the amortization rate, not just the allowance. Over-allowance amortized inside rent is borrowing. Push the rate down, ask for a prepayment right at par, and confirm the amortization stops at lease expiration rather than surviving into renewal rent.

Cap your exposure and define who owns overruns. Establish a guaranteed maximum price with the GC. Define in the work letter that overruns from landlord-caused changes, base-building deficiencies, or unforeseen hazardous materials are landlord cost, not tenant cost.

Force the soft costs into scope. Explicitly permit the allowance to be spent on A/E fees, permits, low-voltage, and project management. If the landlord refuses, quantify the excluded amount and treat it as a reduction in the effective allowance when comparing buildings.

Control the contractor selection. Ask for the right to competitively bid to at least three qualified GCs with healthcare experience, including one of your choosing. If the landlord insists on their contractor, negotiate open-book pricing and a capped construction-management fee.

Fix the approval clock. Both sides should have stated business-day windows to review and approve drawings, with deemed-approval if the window lapses. Silent landlords are a common source of delay that tenants end up paying for.

Address unused allowance. If the buildout comes in under, negotiate the balance as rent credit rather than letting it evaporate. Landlords resist this, but partial credit is frequently obtainable.

Confirm the operating expense treatment. Make sure the landlord's TI capital isn't quietly recovered a second time through the operating expense pass-through, and that any capital improvement amortization in the expense base is capped and limited to items that actually reduce operating cost.

How medical TI compares to the rest of the commercial market

It helps to place medical inside the broader commercial leasing picture, because the same landlord capital competes across product types.

Conventional office allowances are set largely by market softness — in high-vacancy submarkets, landlords buy occupancy with capital, and allowances plus free rent can reach levels that would have been unthinkable a decade ago. Medical office has behaved differently: occupancy has generally been stickier, tenants renew at higher rates because relocating a patient panel is genuinely costly, and landlords price that stability in. Stickier tenancy cuts both ways for the tenant — it means landlords value you, but it also means they know your switching costs are high at renewal.

Compare the cost drivers across property types and the medical premium becomes intuitive. Warehouse and industrial buildouts are cheap per square foot because the space is mostly volume with minimal partitioning. Restaurant buildouts rival or exceed medical because of kitchen exhaust, grease interceptors, and utility loads. Lab and life-science space exceeds most clinical space because of fume-hood exhaust and utility redundancy. Medical sits in the upper band, driven by room count, MEP density, and code, not by finish luxury.

Two adjacent dynamics are worth watching. First, the migration of clinical services into retail and former big-box space — urgent care, dialysis, imaging, and ambulatory surgery moving into strip centers and vacated retail boxes. These conversions carry a distinct cost profile: generous parking and visibility, but often inadequate electrical service, no existing plumbing distribution across a wide floor plate, and structural systems never designed for equipment loads. The rent looks like a bargain; the buildout frequently isn't.

Second, health-system consolidation changes who signs. When a hospital system absorbs an independent practice, the lease negotiation shifts to a corporate real estate team with standard forms, national contractor relationships, and volume pricing. Independent practices negotiating alone against that same landlord should assume the landlord's expectations were shaped by those larger deals, and should press for the comparable treatment their term length justifies.

Finally, note the direction of the underlying cost curve. Skilled trade labor in mechanical, electrical, and plumbing remains the tightest constraint on medical construction, and it's the same labor pool competing for data center, industrial, and life-science work. When that demand is strong, medical fit-out pricing follows regardless of what happens to material indices. That's the structural reason a tenant should treat any published national average as a starting hypothesis to be tested against a real bid — not as a number to negotiate toward.

Related questions

Does the TI allowance cover medical equipment?

Almost never. Allowances typically fund construction and permanently affixed improvements. Exam tables, imaging hardware, sterilizers, furniture, and IT gear are separate capital, often financed through an equipment lender. The buildout must accommodate them, but the equipment itself is the tenant's cost.

Is a second-generation medical suite always cheaper?

Usually, but verify. Inherited plumbing, exam-room partitions, and compliant egress save real money. However, an outdated layout that fights your workflow, undersized electrical service, or aging HVAC can cost more to correct than building fresh from a good shell.

Who pays if we hit asbestos during demolition?

That should be the landlord's cost, and the lease should say so explicitly. Pre-existing hazardous materials in the base building are ordinarily a landlord responsibility, but silent leases create disputes. Add a carve-out and make the deal contingent on a satisfactory Phase I assessment.

Should a small practice take a turnkey deal?

Turnkey suits capital-constrained tenants and simplifies risk, but only if the delivery specification is documented room by room and finish by finish. Without that detail, the landlord builds to their standard, not your clinical workflow, and changes become expensive change orders.

How long should we expect permitting to take?

It varies enormously by jurisdiction and use. A straightforward primary care fit-out in a permissive market may clear building review in weeks; anything requiring state health-facility licensure or a certificate of need can take many months. Confirm the local calendar before committing to an opening date.

FAQ

Why won't anyone give me a straight average TI number for medical space?

Because the variance swamps the mean. Clinical intensity, shell condition, market vacancy, tenant credit, and lease term each move the number substantially, and they move independently. A national average blends a re-tenanted primary care suite with a ground-up surgery center, producing a figure that describes neither. The useful benchmark is a set of recent work letters in your own submarket for your own specialty and term.

What's the single highest-leverage thing I can do to improve my allowance?

Arrive with a priced test fit. A landlord facing a documented scope and a contractor's number responds differently than one facing "we need more TI." It converts the conversation from a negotiation over feelings into a negotiation over a gap, and gaps get split. The professional fee to produce it is small relative to the swing it creates.

Is it better to push for more allowance or lower rent?

Model both as total occupancy cost over the full term, discounted. Allowance is a one-time benefit that arrives when your cash need is highest; rent reduction accrues over years. For a practice funding a new location, front-loaded capital usually wins on cash flow, but if the landlord amortizes the over-allowance at a high rate, the effective borrowing cost can make the rent concession the better trade. Run the numbers rather than assuming.

Can the allowance be spent on architecture and permit fees?

Only if the work letter says so. Many allowances are restricted to hard construction costs. Soft costs — architectural and engineering design, permit and plan review fees, the physicist's shielding design and survey, project management, and low-voltage cabling — can represent a meaningful share of the total. Negotiate their eligibility explicitly and, when comparing two buildings, treat an exclusion as a reduction in the effective allowance.

What happens to allowance money we don't spend?

By default, nothing — the landlord keeps it. Negotiate for the unused balance to convert to rent credit, or at minimum a stated portion of it. Landlords often resist a full conversion but will concede partial credit, particularly when the tenant has agreed to a longer term.

Do I need a healthcare-specific architect, or will a commercial architect do?

For anything beyond cosmetic work in a second-generation suite, use a healthcare-experienced designer. Licensing dimensional requirements, infection-control-driven finish selection, pressure relationships between rooms, and shielding coordination are specialist knowledge. The correction cycle when plan review rejects non-compliant drawings costs far more in schedule than the fee difference costs in dollars.
