A tenant improvement allowance sounds like the landlord paying for your space. Sometimes it is. Often it’s a loan with your rent as the payment.

It depends on the delivery condition and the tenant improvement allowance. The landlord contributes a stated dollar amount per square foot, and you pay for everything above it. Critically, many allowances are amortized back into your rent with interest, which makes them a loan rather than a contribution. Always ask which one you’re being offered.
The Money Pit is a movie about a couple who buy a house, get told the repairs will take two weeks, and then spend the rest of the film watching a staircase collapse. The running joke is the contractor’s answer to every question: two weeks.
Commercial buildouts have their own version of that joke, and the punchline is a dollar figure instead of a timeline. The landlord offers you fifty dollars a square foot and it sounds generous, right up until you find out three things: what condition the space is actually being delivered in, whether that fifty dollars is a gift or a loan, and when you actually get the money.
These terms get used loosely, including by people who should know better. They are not interchangeable, and the gap between two of them can be six figures.
| Delivery condition | Typically includes | You are buying |
|---|---|---|
| Cold shell | Structure, slab, utilities stubbed to the building | HVAC, restrooms, electrical distribution, fire sprinklers, insulation, everything |
| Warm shell | HVAC, restrooms, electrical panel, demising walls, sprinklers | Interior finishes, lighting, flooring, ceilings, your systems |
| Vanilla shell / white box | Finished and painted walls, ceiling grid, lighting, HVAC, restrooms, ADA compliant | Fixtures, equipment, flooring in some cases, branding |
| Second generation, as-is | Whatever the last tenant left | Depends entirely on whether their use matches yours |
Get the delivery condition defined in the letter of intent, item by item, as an exhibit. Not the phrase “warm shell.” The list. Because “warm shell” means something slightly different to every landlord in this county, and the ambiguity always resolves in the direction of the person who drafted it.
Here is the distinction that costs people the most money, and it is almost never explained.
A true TI allowance is landlord capital. They spend it, it improves their building, and it does not come back to you.
An amortized TI allowance is a loan. The landlord funds the improvements and adds the cost to your rent over the term, with interest, commonly in the 8 to 10 percent range. It shows up as a slightly higher base rent, or as a separate line item, and it is frequently presented in exactly the same language as a true allowance.
Run the numbers on a 2,000-square-foot space with a $50-per-square-foot allowance on a five-year term:
| Structure | What you get | What it costs you |
|---|---|---|
| True allowance | $100,000 toward buildout | Nothing additional |
| Amortized at 9% over 60 months | $100,000 toward buildout | Roughly $2,076 per month, about $124,600 total |
Both deals are called a fifty-dollar TI package. One of them adds about $1.04 per square foot per month to your real occupancy cost.
Amortized TI is not a scam. Sometimes it is exactly the right tool because it converts capital you do not have into a monthly cost you can support. But you have to know which one you are signing, and you have to include the amortization in your occupancy-cost math. Ask directly: Is this allowance amortized, and at what rate?
The default mechanics are worse for your cash flow than most tenants expect. A typical reimbursement structure requires:
Then payment within 30 to 60 days.
That means you front the entire buildout, wait for inspections to clear, chase lien releases from six subcontractors, and get reimbursed two to three months after you finish. On a $150,000 buildout with a $100,000 allowance, you are carrying $150,000 of working capital, not $50,000.
Negotiate progress draws. Ask for monthly or milestone-based disbursement against approved invoices and conditional releases. Landlords do this routinely when asked. They almost never offer it.
Landlord-built, turnkey. The landlord’s contractor builds to an agreed plan. It is simpler for you, but you pay for that simplicity through the contractor’s pricing and a landlord construction-management fee, often 3 to 5 percent. You also have limited control over schedule, which matters when your opening date is a business decision.
Tenant-built with an allowance. You hire the contractor, control cost and schedule, and carry the risk of overruns and delays. It can produce better economics when you or someone on your team understands construction. It can be worse when nobody does.
Either way, the lease will require landlord approval of your plans, contractor, and insurance. Build approval timelines into your schedule, and negotiate a deemed-approved provision if the landlord does not respond within a stated number of business days. Otherwise, your schedule is hostage to someone else’s inbox.
This is the fork in the road, and almost every buildout mistake traces back to getting it wrong.
Like-kind: restaurant into restaurant, dental into dental, salon into salon. Your job is verification, not construction. The infrastructure exists. The question is whether it is adequate, functional, and legal.
Verify before the LOI:
Conversion: office into dental, retail into restaurant, warehouse into fitness. Now you are pricing real construction, and the correct order is not optional:
Contractor walkthrough. Real bid. Then rent negotiation.
The buildout cost determines what rent your business can support. Agreeing to rent before knowing the construction number is agreeing to a number you cannot evaluate. Our co-founder is a licensed contractor. That is why we walk conversion spaces with a scope in hand before anyone discusses rate.
Restoration and removal. Many leases require you to remove your improvements and restore the premises to original condition at your expense when the lease ends. On a heavy buildout, that obligation can run into six figures at exactly the moment you have the least reason to spend it.
Negotiate it now. Either strike the restoration obligation, limit it to trade fixtures and specifically identified items, or get a written agreement that improvements approved by the landlord may remain. This costs nothing to ask for at the LOI stage and is nearly impossible to fix later.
We are on your
side of the table.
A $100,000 allowance amortized at 9 percent over five years costs you roughly $124,600 in rent. It is still called an allowance.
The buildout number determines the rent you can afford. That means the construction conversation has to happen before the rent conversation, not after.
A stated dollar amount per square foot the landlord contributes toward building out your space. It may be true landlord capital, or it may be amortized back into your rent with interest, which makes it a loan. Always ask which structure you are being offered.

The allowance number is the one people negotiate. The delivery condition, the amortization rate, the draw schedule, and the restoration obligation are the four that determine what the deal actually costs.
None of those four are hard to ask about. They just have to be asked before the rent is agreed, because after that the answers stop being negotiable and start being information.
If you are looking at a space right now, do you know in writing exactly what condition it will be delivered in, item by item?
