The tenant improvement allowance is one of the most valuable numbers in a commercial lease, and it is easy to lose track of once the lease is signed: the total dollars, the rate per rentable square foot, the deadline to spend it, what happens to the unused balance, and how it is amortized or treated as an ASC 842 lease incentive. Upload the lease and any work letter or amendment, and get the TI allowance and every term attached to it pulled into structured fields, each citing its source page. Free to try, no demo, no minimum.

A TI allowance is not a single kind of term. How it is funded and what happens to leftover dollars change the cash flow and the accounting, and each structure hides in a different part of the lease or work letter. The abstract has to identify which one applies and pull the fields that go with it. Each row names the structure, how the money reaches the tenant, and what the abstract must capture first.
| TI allowance structure | How the money reaches the tenant | What the abstract must capture first |
|---|---|---|
| Turnkey / landlord-built | Landlord builds to an agreed spec and owns the improvements | The build-out spec, who owns the improvements, and any overage the tenant pays |
| Cash allowance (reimbursement) This tool | Landlord reimburses the tenant against paid invoices up to a cap | The dollar cap, $/SF, draw conditions, spend deadline, and the unused-balance rule |
| Amortized allowance | Landlord funds the work and recovers it through added rent at an interest rate | The amortized amount, the rate, the recovery period, and any early-termination payoff |
| Rent abatement in lieu of TI | Free-rent months substitute for a cash allowance | The number of abated months, when they apply, and how they interact with the ASC 842 measurement |
Structures reflect standard commercial leasing practice; the terms that actually apply come from your specific lease and work letter. LeaseAbstractors extracts what the document says rather than assuming a market structure.
A TI allowance touches cash, construction, and accounting all at once, so the fields that matter are spread across the lease, the work letter, and any amendment. These are the ones the abstraction pulls out and ties back to the source.
The total TI allowance in dollars and the rate per rentable square foot, so the figure the deal was negotiated on sits on one line instead of buried in a work letter.
The date by which the tenant has to spend or draw the allowance and what happens to anything left over, whether it is forfeited, converted to rent credit, or lost, so no unspent dollars slip away.
The lien waivers, paid invoices, and sign-offs the landlord requires before it releases funds, extracted so the tenant knows exactly what unlocks each draw.
Where the allowance is amortized into rent, the amount, the interest rate, the recovery period, and any payoff owed on early termination, so the true cost of the money is visible.
Whether the allowance is a lease incentive that reduces the right-of-use asset, and whether the improvements are lessee or lessor assets, the distinction that decides how it is booked.
Each extracted value links to the page and clause it came from, so your accounting or asset-management team can verify the cap or the deadline in seconds instead of rereading the work letter.
From the lease and its work letter to a clean, source-linked TI allowance record, with the deadline and accounting terms separated out.
Add the base lease, the work letter or improvement exhibit, and any amendment that changed the allowance. Scans are fine.
The model returns the allowance amount and $/SF, the spend deadline and unused-balance rule, the draw conditions, the amortization terms, and the ownership of the improvements as structured fields.
Each field links to its source page, so you confirm the cap, the deadline, and the amortization rate in minutes and fix anything before it reaches your model or system of record.
Download the record and load it into your rent roll, lease administration system, or ASC 842 workpapers, or hand it to the deal team.
Last updated July 2026. What a TI allowance is, how the structures differ, how it is treated under ASC 842, and how AI abstraction pulls it from every lease.
Tenant improvement allowance abstraction is the work of reading a lease and its work letter and pulling the TI allowance and every term attached to it into structured fields you can track and account for. That means the total dollars and the rate per rentable square foot, the deadline to spend or draw the allowance, what happens to any unused balance, the draw conditions, whether the money is amortized into rent, and how it is treated as a lease incentive under ASC 842. It is the same discipline as any commercial lease abstraction, focused on the one number a tenant most often leaves on the table because the deadline passed or the balance was never drawn.
A tenant improvement allowance, or TI allowance, is money a landlord agrees to contribute toward building out a tenant's space, almost always quoted as a total dollar figure and as dollars per rentable square foot. It funds work like walls, flooring, electrical, and finishes that turn a shell or a prior tenant's space into something usable. The allowance is negotiated as part of the deal economics and documented in the lease or a separate work letter, and the terms around it, the spend deadline, the draw process, and what happens to unspent dollars, are where tenants most often lose value.
Under ASC 842 a tenant improvement allowance is generally a lease incentive. When the allowance reimburses the tenant for assets the tenant owns, it reduces the lease payments used to measure the right-of-use asset and lease liability, so a larger allowance produces a smaller ROU asset. When the improvements are landlord assets, the payment is not a lessee incentive in the same way, and the accounting follows the ownership. The timing matters too: an allowance receivable at commencement is treated differently from one contingent on future spending. Because the answer turns on ownership of the improvements and on the exact wording, abstracting the allowance and its conditions is the first step in getting the ASC 842 lease data right. For the full mechanics, see the guide to how a tenant improvement allowance works.
It depends entirely on the lease, which is exactly why the clause has to be abstracted. Many leases forfeit any unused allowance after a hard spend deadline, so dollars the tenant paid for in the rent simply disappear. Others let the tenant apply the leftover to rent as a credit, and a few allow it to fund additional work or fixtures. The deadline and the unused-balance rule usually sit in the work letter rather than the body of the lease, so they are easy to miss until it is too late. Pulling the deadline into a dated field, alongside the other critical dates in the lease, is what keeps an allowance from lapsing unspent.
An amortized TI allowance is one the landlord funds up front and then recovers through additional rent over the term, with interest, so it behaves like a loan the tenant repays inside the rent. The lease will state the amortized amount, the interest rate, and the recovery period, and often a payoff the tenant owes if it terminates early. That payoff can be a meaningful number, which is why the amortization terms belong in the abstract next to the base rent. Abstracting them lets a tenant see the true cost of the improvement money instead of treating it as free.
Yes. AI reads the lease and work letter and returns the allowance amount, the $/SF, the spend deadline, the draw conditions, the amortization terms, and the ownership of the improvements as structured data far faster than reading them by hand, and a source-linked tool lets a reviewer confirm each value against the page it came from. The fields that matter most, the cap, the deadline, and any amortization payoff, are the ones to check first on your own most complex lease. LeaseAbstractors does this free with no demo, and the same engine runs a whole portfolio through the lease abstraction software, with the extracted fields lining up with the commercial lease abstract template.

Talk to our teamA tenant improvement allowance is money a landlord contributes toward building out a tenant's space, usually quoted as a total dollar figure and as dollars per rentable square foot. It funds finishes, walls, electrical, and other work, and is documented in the lease or a separate work letter.
It is generally a lease incentive. When it reimburses the tenant for tenant-owned assets, it reduces the lease payments used to measure the right-of-use asset and lease liability, so a larger allowance yields a smaller ROU asset. When the improvements are landlord assets, the accounting follows the ownership.
It depends on the lease. Many leases forfeit any unused allowance after a spend deadline, others convert it to a rent credit, and a few let it fund extra work. The deadline and rule usually sit in the work letter, so abstracting them keeps dollars from lapsing.
One the landlord funds up front and recovers through added rent over the term with interest, so it works like a loan repaid inside the rent. The lease states the amount, rate, and recovery period, and often a payoff owed on early termination, which belongs in the abstract.
It varies widely by market, asset class, and lease term, so the only reliable figure is the one in your lease. That is why the abstract pulls the actual dollar amount and $/SF from the document rather than assuming a market rate.
Yes. AI reads the lease and work letter and returns the allowance amount, $/SF, spend deadline, draw conditions, amortization terms, and improvement ownership as structured data, each field linked to its source page so a reviewer can verify it in seconds.
