How Tenant Improvement Allowances Work

A large TI allowance doesn’t automatically mean a cheaper build-out. Here’s what the number covers and what tenants should negotiate before signing.

What you should know

  • An allowance is only as valuable as the work it pays for. Price the build-out before you negotiate the number.
  • The work letter, not the headline figure, decides what the money covers, when it is paid and who carries the risk of overruns.
  • Most allowances are paid as reimbursement, so tenants often need to fund construction first and be repaid later.
Where the tenant’s exposure comes from
  1. Total build-out costConstruction, design, permits, cabling and anything else the plan requires. Illustrative: $1,200,000.
  2. Landlord contributionThe allowance, or the value of work the landlord performs. Illustrative: −$800,000.
  3. Tenant exposureWhat the company funds itself, before any overruns. Illustrative: $400,000.

Illustrative figures only, not market pricing. Costs and allowances vary by space, scope and deal.

A tenant improvement allowance, usually called TI or a TI allowance, is money a landlord contributes toward building out or improving a space. It is one of the largest items in many New York office deals, and one that is easy to misread.

The mistake is treating the allowance as the measure of the deal. A larger allowance on a space that needs far more work can leave a tenant spending more of its own money than a smaller allowance on a space that needs very little.

What TI is, and what it isn’t

TI is a landlord contribution toward improvements to the space: walls, ceilings, lighting, mechanical and electrical work, finishes and similar work. It is typically expressed per rentable square foot and set out in the lease’s work letter.

It is not free money for anything the company needs. What it can be spent on, how it is paid and what happens to any balance are all defined by the lease. It also is not the only way a landlord can contribute: sometimes the landlord does the work itself instead.

Two structures: landlord work or a tenant allowance

How the landlord’s contribution is delivered
Landlord performs the workTenant performs the work with an allowance
Who manages constructionThe landlord and its contractorThe tenant, its architect and contractor
Tenant control over design and scheduleLowerHigher
Risk of cost overrunsUsually the landlord’s, within the agreed scopeUsually the tenant’s, above the allowance
Cash timingTenant generally pays nothing for the agreed scopeTenant often funds first and is reimbursed
What to get in writingDetailed scope, drawings, finishes and delivery dateEligible costs, draw process, deadlines and treatment of unused funds

General comparison. Many deals combine the two, with the landlord performing base work and the tenant finishing the space.

Neither is better in general. Landlord work suits a tenant that wants a defined result and less management. A tenant allowance suits a company that wants control over design and is prepared to run a project, or to hire someone who can.

The work letter

The work letter is the exhibit to the lease (see the lease glossary) that sets out the construction arrangements: who performs which work, to what standard, on what schedule, who approves plans and contractors, and how the allowance is paid. It is where most of the value of the allowance is won or lost.

A vague work letter is a risk. “Landlord will build out the space” means little without drawings, a finish standard and a delivery date.

What the allowance usually covers

Leases often limit the allowance to “hard costs,” meaning physical construction, and cap or exclude “soft costs.” Common questions include:

  • Hard costs: demolition, partitions, ceilings, lighting, HVAC distribution, electrical, finishes.
  • Soft costs: architecture, engineering, permits, project management and expediting. Often capped as a share of the allowance.
  • Cabling and technology: sometimes eligible, sometimes not.
  • Furniture, equipment and moving costs: frequently excluded, though some landlords allow part of the allowance for them. Ask directly.

When the money is paid

Many allowances are paid as reimbursement. The tenant pays its contractor, submits invoices and lien waivers, and the landlord reimburses in installments or at completion. That creates a cash-flow gap that can be significant for a growing company.

Ask when draws can be made, what documentation is required, how long the landlord has to pay and whether any amount is held back until final completion. Some tenants negotiate for the landlord to pay the contractor directly.

Overruns and unused allowances

If the build-out costs more than the allowance, the tenant usually pays the difference. That is why scope matters as much as the number: change orders, late design decisions and unforeseen conditions in older buildings are the usual causes of overruns.

If the build-out costs less, the lease decides what happens to the balance. Some leases let unused allowance be applied as a rent credit, sometimes with a cap; many simply let it lapse after a deadline. Negotiate this at the LOI stage, not after construction.

Design the scope before you sign

The strongest way to negotiate an allowance is to know what the space needs. A test fit shows what the plan requires, and an early budget shows what it will cost. With those, a tenant can compare a smaller allowance on a space that needs little work against a larger one on a space that needs a lot, on the same basis. See how to compare two NYC office deals and build-out vs. renovation.

This is also where construction management helps. Someone who has priced similar work can tell you whether an allowance is realistic before you rely on it.

What to negotiate

Before the LOI is signed

  • Landlord work vs. allowance, and the scope of each in writing
  • Allowance amount relative to a priced test fit
  • Eligible costs, including soft costs, cabling and any furniture allowance
  • Draw schedule, documentation and payment timing
  • Treatment of unused allowance, and the deadline to use it
  • Who approves plans and contractors, and how long approvals take
  • Restoration obligations for the work you build

The bottom line

A TI allowance is a contribution toward a specific scope of work, on specific terms. Its value depends on what the space needs, what the money covers, when it is paid and who carries the risk if the build-out runs over.

Price the build-out first, then negotiate the allowance and the work letter together. The headline number is only the start.

Frequently asked questions

What is a tenant improvement allowance?
It is money a landlord contributes toward building out or improving a tenant’s space, usually expressed per rentable square foot. The lease and its work letter set out what the allowance can be used for, how and when it is paid, and what happens to any unused balance. The landlord may instead perform the work itself as part of the deal.
Who controls the TI money?
The landlord usually holds the funds and pays them out under the terms of the work letter, often as reimbursement after the tenant submits invoices and lien waivers. The tenant controls the design and construction when it performs the work, subject to the landlord’s approval of plans and contractors. When the landlord performs the work, it controls both the money and the construction.
Can TI pay for furniture?
Sometimes, but often not. Many leases limit the allowance to physical improvements and exclude or cap furniture, equipment, cabling and moving costs. Some landlords agree to let a portion be used for furniture or technology. If that matters to your budget, ask for it explicitly in the letter of intent rather than assuming it.
What happens if construction costs more than the allowance?
In most leases the tenant pays the difference. Overruns usually come from scope changes, late design decisions or conditions discovered once work begins, particularly in older buildings. A priced test fit, a clear work letter and a contingency in the budget reduce the risk. If the landlord performs an agreed scope, overrun risk within that scope is often the landlord’s.
What happens to unused TI?
It depends on the lease. Some allow unused allowance to be credited against rent, often up to a cap; others let it expire after a deadline or keep it with the landlord. Because the answer varies so much, negotiate the treatment of any balance, and the deadline for using it, before the lease is signed.
When should a tenant negotiate the allowance?
At the proposal and LOI stage, with a test fit and an early budget in hand. Once business terms are agreed, landlords rarely reopen the allowance. Knowing what the space needs lets a tenant compare offers on the cost it will bear, not on the headline allowance.
