Tenant Improvement Allowance: How TI Works in a Commercial Lease
A tenant improvement allowance (TI allowance) is money a landlord agrees to contribute toward building out or renovating leased commercial space. It is usually stated per square foot, the tenant pays anything above it, and the lease sets the conditions for getting it paid.
How a TI allowance is calculated
The allowance is the per-square-foot rate multiplied by the square footage the lease measures it on. Using illustrative numbers: a lease granting $50 per rentable square foot on 10,000 rentable square feet gives a $500,000 allowance. If the build-out costs $620,000, the tenant funds the remaining $120,000, either directly or, where the landlord agrees, through higher rent over the term.
Two details change the number more than people expect. The first is the measurement basis: rentable square feet include a share of common areas, so an allowance stated on rentable area is larger than the same rate on usable area. The second is the term. Landlords recover the allowance through rent, so a longer lease or a stronger tenant usually supports a larger allowance, and early termination rights often come with an obligation to repay the unamortized portion.
What the allowance can pay for
The lease defines which costs count. Costs outside that definition come out of the tenant's pocket even if allowance money is left over.
Hard costs
Construction itself: demolition, framing, drywall, ceilings, flooring, electrical, plumbing, and HVAC distribution. Almost every allowance covers these.
Soft costs
Architecture and engineering, permits, project management, and sometimes moving costs. Leases often cap soft costs at a share of the total allowance.
Furniture, cabling, and equipment
Often excluded or capped, because they belong to the tenant and leave with it. Check the definition of permitted costs before budgeting for them.
How the money is paid out
An allowance is rarely a lump sum handed over at signing. The usual pattern is reimbursement: the tenant (or its contractor) completes work, submits invoices with lien waivers, and the landlord pays against them, either in progress draws or in one payment at completion. Some landlords also charge a construction supervision fee, typically a percentage of construction cost, and the lease decides whether that fee comes out of the allowance.
The alternatives are a turnkey build-out, where the landlord delivers finished space to an agreed plan and bears the cost risk, and an as-is deal with no allowance, usually offset by lower rent or free rent.
TI terms to track in the lease abstract
The headline allowance is easy to find. The terms that decide whether the tenant actually collects it are scattered across the work letter, the rent section, and the default provisions, which is why they belong in the lease abstract as separate fields.
Allowance amount and basis
The dollar amount or per-square-foot rate, and whether it is measured on rentable or usable square feet. A change in measured area changes the allowance.
Outside date to use it
Many leases say unused allowance is forfeited if not requested by a set date. This is the TI term teams miss most often, and it belongs on the same calendar as renewal and termination notices.
Disbursement conditions
What the tenant has to deliver to get paid: invoices, lien waivers, architect certifications, a certificate of occupancy. Missing paperwork is a common reason payments stall.
Caps and permitted uses
Limits on soft costs, exclusions for furniture and cabling, and whether any unused balance can be applied as a rent credit.
Remedies if the landlord doesn't pay
Some leases let the tenant offset unpaid allowance against rent. If the property is financed, check the SNDA, because lender forms often say a successor landlord is not liable for unfunded allowance.
Ownership and restoration
Whether the improvements become landlord property at the end of the lease, and whether the tenant must remove specialty improvements and restore the space.
Renewals deserve their own check. An extension amendment often grants a fresh refurbishment allowance with a new outside date, and if the abstract is not updated the new money is easy to lose. See how lease amendments change the abstract and why the SNDA on a financed property can limit what a new owner has to fund.
Capturing TI terms with Abstria
Abstria extracts the allowance amount, outside date, disbursement conditions, and related terms as part of the 200+ fields it pulls from each lease and amendment, in 2-5 minutes per document. Each field links back to the clause it came from in the dual-panel editor, so whoever manages the build-out can confirm the condition in the work letter instead of relying on a summary. For the full list of what a lease abstract covers, see the lease abstraction guide.
Tenant improvement allowance FAQ
What is a tenant improvement allowance?
A tenant improvement allowance (TI allowance or TIA) is money a landlord agrees to contribute toward building out or renovating leased commercial space for a tenant. It is usually stated per square foot, and the tenant pays any costs above the allowance.
How is a TI allowance calculated?
Multiply the per-square-foot allowance by the square footage it is measured on. For example, $50 per square foot on 10,000 rentable square feet is a $500,000 allowance. Check whether the lease uses rentable or usable square feet, since the two produce different totals.
What is a typical tenant improvement allowance?
There is no single typical figure. Allowances vary with the market, building class, lease length, the tenant's credit, and whether the space is new or already built out. Longer leases generally support larger allowances because the landlord has more time to recover the cost through rent.
Can unused TI allowance be used for rent?
Only if the lease says so. Some leases allow part of an unused balance to be taken as a rent credit, often with a cap; others say any unused amount is forfeited after the outside date.
Who owns tenant improvements when the lease ends?
Usually the landlord, unless the lease says otherwise. Many leases also give the landlord the right to require the tenant to remove specialty improvements and restore the space, which is a cost to plan for at exit.
Are leasehold improvements the same as tenant improvements?
They describe the same physical work from different angles. "Tenant improvements" is the leasing term for the build-out; "leasehold improvements" is the accounting term for those improvements once they are recorded as an asset by whoever paid for them. Who capitalizes and depreciates them depends on who funds and owns the work, which is a question for your accountants.
What is the difference between tenant improvements and a TI allowance?
Tenant improvements are the physical changes made to the space. The TI allowance is the landlord's money that pays for some or all of them.
