What Is TI in Real Estate? Tenant Improvement Allowances Explained

If you've ever negotiated a commercial lease in South Florida for an office, retail space, medical suite, or industrial unit, you've almost certainly encountered the term TI, or tenant improvement. TI real estate negotiations are often the most financially significant part of a commercial lease. Understanding how TI works can save tenants real money and gives landlords a tool to attract quality occupants. Here's what you need to know.

What is a tenant improvement allowance?

A tenant improvement (TI) allowance is a sum of money a commercial landlord agrees to contribute toward the cost of building out or improving the leased space to suit the tenant's specific needs. It's typically expressed as a dollar amount per square foot. For example, $30/SF TI on a 2,000 SF office space means the landlord contributes $60,000 toward the buildout.

TI covers a wide range of improvements depending on the space and the lease terms: new walls or partitions, flooring, ceiling systems, lighting, HVAC modifications, plumbing (for medical or food service uses), electrical upgrades, paint, millwork, and signage. The specific eligible uses are defined in the lease agreement. Read that section carefully before you sign anything.

How TI allowances are structured

TI allowances are disbursed in a few different ways depending on how the lease is written:

• Landlord-managed buildout: The landlord hires and pays contractors directly, delivering a completed space. The tenant has input on specifications, but the landlord manages the process.
• Tenant-managed buildout with landlord reimbursement: The tenant hires their own contractors, completes the work, submits invoices, and the landlord reimburses up to the TI amount. This approach gives the tenant more control but requires upfront capital.
• Rent credit: In some deals, the TI allowance takes the form of a rent abatement period rather than a direct cash contribution to construction costs.

TI in South Florida's commercial market

South Florida's commercial real estate market has historically offered competitive TI allowances, especially in Class A and B office space across Boca Raton, Fort Lauderdale, and Miami. As of 2026, TI negotiations vary considerably by submarket and asset type:

• Office space: $40 to $80/SF is common for credit tenants on five-year-plus leases in Class A buildings
• Retail space: TI is typically lower ($15 to $40/SF) and more focused on landlord-controlled improvements
• Industrial/flex: Minimal TI unless the tenant needs a significant office build-out within the industrial shell
• Medical office: TI requirements run high here. Complex plumbing, electrical, and ADA compliance needs push build-out costs to $80 to $150/SF for full medical suites

Key TI negotiation points for South Florida tenants

When negotiating TI in a South Florida commercial lease, focus on the details that actually move money:

• Eligible uses: Define exactly what costs are covered. "Hard costs only" versus "hard and soft costs including architect and permit fees" is a meaningful financial difference.
• Disbursement timing: When and how is the money released? Requiring upfront receipts before reimbursement can strain cash flow, particularly for smaller tenants.
• Unused TI: If the buildout comes in under budget, do you forfeit the balance? Some leases allow unused TI to convert to rent abatement. Many do not.
• Recapture provisions: Early lease termination may trigger a requirement to repay a prorated share of the TI the landlord already funded. Know these terms before you sign.
• Approval process: Most landlords require sign-off on contractor selection and construction plans before releasing funds. Build that review timeline into your buildout schedule or the delays will cost you.

Frequently asked questions

Is a TI allowance the same as free rent?

No. Free rent is a period where no rent is owed, often granted at the start of a lease to allow move-in time. A TI allowance is money specifically designated for construction and improvements to the space. Some deals include both, and some leases convert unused TI into free rent, but they are separate concessions.

Who owns the improvements after the lease ends?

In most commercial leases, improvements funded by a TI allowance become the landlord's property at lease end. The lease may also require the tenant to restore the space to its original condition, depending on the scope of the buildout. Confirm this in the lease before construction begins.

Can I negotiate TI even in a tight South Florida market?

Yes, though the amount and structure depend heavily on your lease term, credit profile, and the landlord's current vacancy situation. Longer commitments, stronger financials, and longer vacancy periods at the property all improve your negotiating position. A commercial broker familiar with local submarket conditions can tell you what's realistic before you go to the table.

What if construction costs exceed the TI allowance?

Any costs above the TI amount are the tenant's responsibility. This is called a tenant overrun. Budget carefully and get competitive contractor bids before signing. Locking in a GMP (guaranteed maximum price) contract with your contractor limits exposure if material costs shift during the project.
