Tenant Improvement Allowance in Chicago (2026): How Healthcare and Dental Tenants Negotiate Build-Out Dollars

Most healthcare and dental tenants in Chicago negotiate base rent aggressively — and then leave tens of thousands of dollars on the table by under-negotiating the tenant improvement allowance (TI).

For a dental operatory, a med spa treatment suite, or a physical therapy clinic, build-out costs are often the single largest upfront expense of opening a location. The TI allowance determines how much of that cost the landlord absorbs.

This guide covers:

• What a TI allowance actually is (and is not)
• Typical TI structures in Chicago and the suburbs in 2026
• Why healthcare build-outs cost more — and justify larger allowances
• How landlords recover TI through rent
• How to negotiate TI in your LOI
• The traps: "as-is" delivery, amortized TI, and clawbacks

What Is a Tenant Improvement Allowance?

A tenant improvement allowance is a fixed amount of money — usually expressed in dollars per square foot — that the landlord contributes toward the tenant's build-out of the space.

It typically covers:

• Demolition and construction of walls, rooms, and operatories
• Flooring, ceilings, and finishes
• Electrical, plumbing, and HVAC modifications
• Permits and architectural fees (sometimes negotiable)

It usually does not cover:

• Movable equipment (dental chairs, imaging, lasers)
• Furniture and signage
• Soft costs, unless explicitly negotiated into the lease

How TI Works Together With Base Rent

TI is never "free money." Landlords underwrite the allowance against the total value of the lease: base rent, annual rent escalations, and term length.

The practical rule in the Chicago market:

• Longer term = more TI. A 10-year lease supports a significantly larger allowance than a 5-year lease, because the landlord has more time to recover the investment.
• Higher rent = more TI. Some landlords will offer additional allowance in exchange for a higher starting rent or steeper escalations — effectively financing your build-out through the lease.
• Stronger tenant = more TI. Landlords invest more in tenants they believe will renew. Healthcare users are attractive precisely because their build-outs make them "sticky."

Why Healthcare and Dental Build-Outs Justify Larger Allowances

A standard office build-out and a dental or medical build-out are not the same project. Healthcare spaces require plumbing to multiple rooms, reinforced electrical capacity, medical gas lines in some cases, lead shielding for imaging, and ADA-compliant patient flows.

That is why dentists, healthcare providers, and med spa operators should never accept a "standard office TI" figure as a starting point. The correct benchmark is the cost of a comparable medical build-out in your submarket — not what the landlord gave the insurance agency down the hall.

Landlords in Naperville, Schaumburg, and the North Suburbs increasingly understand this: with suburban asking rents rising and quality space concentrating demand, a well-capitalized healthcare tenant is one of the strongest covenants they can sign — and the TI package is where that leverage shows up.

How Landlords Actually Calculate the TI Number

Understanding the landlord's math is the fastest way to negotiate credibly. From the landlord's side, a TI allowance is a capital investment recovered through the lease. The underwriting logic looks like this:

• Total lease value: base rent × square footage × term, plus escalations, minus free rent and commissions.
• Payback period: the landlord wants the TI (plus broker commissions and downtime) recovered well inside the initial term — which is why a 5-year deal caps the allowance so quickly.
• Residual value of your improvements: a generic office build-out has little reuse value; a plumbed medical suite makes the space more valuable to the next healthcare tenant. Smart tenants use this argument explicitly: your improvements upgrade the landlord's asset.
• Credit and covenant: a tenant with strong financials, a signed associate agreement, or an established multi-location operation de-risks the investment and unlocks a bigger number.

This is also why the same landlord can rationally offer two different tenants two very different TI packages for the same suite. The allowance is priced against risk and lease value — not against a rate card. Presenting your practice as a low-risk, long-term covenant is a negotiation strategy in itself.

Shell Space vs. Second-Generation Space: Two Different TI Conversations

The delivery condition of the space changes the entire TI negotiation:

• Cold or warm shell (new construction): you're building everything — HVAC distribution, plumbing runs, walls, finishes. Build-out costs are highest here, and the TI conversation starts from a much larger base. Expect longer construction timelines and negotiate the rent commencement date accordingly: rent should not start while you're still pulling permits.
• Second-generation office space: partially useful infrastructure, but medical conversion (plumbing to operatories, electrical upgrades) still drives significant cost. This is the most common scenario in suburban Chicago inventory.
• Second-generation medical or dental space: the jackpot — if the layout fits. Existing medical plumbing and electrical can cut build-out costs dramatically, which is why former practice locations lease quickly and why site selection should actively hunt for them before they hit the open market.

A related structure worth knowing: turnkey build-out, where the landlord delivers the finished space to an agreed specification instead of writing a TI check. Turnkey shifts construction risk to the landlord — attractive for first-time owners — but you give up cost transparency and control over contractors and finishes. If you take a turnkey deal, lock the specification in exhibit-level detail; "building standard finishes" means whatever the landlord's contractor says it means.

"As-Is" Delivery: Read This Clause Twice

Many second-generation spaces are offered in as-is condition. That can be an opportunity — a former dental suite with existing plumbing can save you six figures — or a trap, if the existing infrastructure fails inspection or doesn't match your layout.

Before accepting an as-is space, complete technical due diligence: verify HVAC capacity, plumbing condition, electrical load, and code compliance. "As-is" combined with a thin TI allowance transfers all construction risk to you.

How to Negotiate TI in Your LOI

The TI allowance is won or lost at the letter of intent stage, not in the lease draft. By the time attorneys are involved, the economics are largely set.

What to put in the LOI:

• A specific dollar-per-square-foot figure based on real construction bids for your use — not a round number.
• What the allowance may be spent on, including architectural fees, permits, and — if possible — a portion usable as free rent if unspent.
• Disbursement terms: when and how the landlord pays (progress payments vs. reimbursement after completion — this affects your cash flow during construction).
• Delivery condition of the premises, so the TI applies to your improvements, not to fixing the landlord's deferred maintenance.
• Fallback structure: if the landlord won't move on TI dollars, negotiate additional free rent months or reduced escalations instead. The net effective economics matter more than the label.

In a NNN lease, also confirm that your own build-out doesn't increase the property's operating expenses passed back to you — for example through higher insurance or tax reassessment triggered by the improvements.

Amortized TI and Clawbacks: The Fine Print

Two structures deserve extra scrutiny:

• Amortized TI: the landlord "lends" you the allowance and recovers it through added rent, often at an implied interest rate of 8–10%. Sometimes this is worth it; often a bank or SBA loan is cheaper. Run both numbers.
• Clawback provisions: if you default or terminate early, the unamortized TI becomes immediately repayable. If you're negotiating a sublease or assignment right, make sure the clawback doesn't survive in a way that kills your exit options.

What Healthcare Tenants Should Do Before Signing

• Get real construction bids for your specific use before negotiating TI — leverage requires numbers.
• Benchmark the landlord's offer against comparable medical deals in your submarket, not office averages.
• Negotiate TI, free rent, base rent, and escalations as a single economic package.
• Verify delivery condition and disbursement mechanics in the LOI.
• Model the amortized alternative before accepting it.

Frequently Asked Questions

What is a typical TI allowance in Chicago in 2026?

It varies widely by submarket, building class, lease term, and use. Standard office deals may see modest allowances, while long-term healthcare leases in competitive suburban submarkets can command substantially larger packages — the key is benchmarking against comparable medical deals, not office averages.

Does the TI allowance cover dental equipment?

No. TI covers improvements to the real estate — walls, plumbing, electrical, finishes. Movable equipment like chairs and imaging is the tenant's cost, though the plumbing and electrical infrastructure that serves it is typically TI-eligible.

Is it better to take more TI or more free rent?

It depends on your cash position. TI helps if construction costs are your constraint; free rent helps if operating runway is. Negotiate them as one package and compare net effective rent across scenarios.

Can I negotiate TI on a renewal?

Yes. A refresh allowance on renewal is common and often overlooked — especially if you hold a lease renewal option. Landlords would rather fund a refresh than lose a healthcare tenant with an expensive build-out.

Who controls the construction — tenant or landlord?

Either, and it's negotiable. Tenant-controlled build-out (with TI reimbursement) gives you contractor choice and cost control; landlord-controlled (turnkey) shifts risk but reduces transparency. For specialized healthcare build-outs, tenant control with a clear disbursement schedule is usually the stronger structure.

Does unused TI allowance carry over or convert to rent credit?

Only if the lease says so. By default, unspent allowance is simply lost. Negotiating a clause that converts unused TI into free rent or a rent credit is one of the cheapest asks in the entire deal — landlords rarely volunteer it, but often accept it.
