A tenant improvement allowance an owner grants is written in a lease. The work it pays for is scoped in a construction contract. The two documents are drafted by different people at different times, and the space between them is where the money goes.
Two documents describing one boundary
The lease says the landlord delivers the premises in a defined condition and contributes a stated amount per square foot toward the tenant work. The construction contract says what the base building package includes.
Both documents are internally consistent. Neither was written with the other open on the desk.
The lease exhibit describing the delivery condition is usually short, often a page, and frequently written by a leasing team using language from a previous deal. The construction scope is long, detailed and written by a preconstruction team working from drawings.
Where the lease promises something the construction scope does not include, the owner pays for it and it is not funded by anything. Where the construction scope includes something the lease treats as tenant work, the owner has paid for it twice: once in the base building and once through the allowance.
Both errors are common and only the second is ever discovered, because it shows up as a credit request from a tenant.
What a tenant improvement allowance an owner grants actually has to cover
The number is usually quoted per square foot, which makes it easy to compare against the market and easy to misjudge against the building.
Three things determine whether the figure is adequate, and none of them is the market rate.
The delivery condition. Space delivered as a bare slab with capped utilities needs a much larger allowance than space delivered with a finished ceiling grid, distributed mechanical and a sprinkler layout. The same dollar figure means two different things in those two buildings.
The use. A law firm fit out, a medical suite and a restaurant consume allowances at very different rates, and the restaurant consumes it fastest because of grease exhaust, gas, water and structural penetrations.
Who manages the work. Tenant managed fit out with a landlord contribution behaves differently from landlord managed work billed against the allowance, and the second exposes the owner to overruns the first does not.
An allowance quoted without those three stated is a number without a basis, which is the general problem covered in construction allowance management.
The seven items that sit in the gap
The same list appears on most commercial jobs, and each one is owned by nobody until somebody asks.
Storefront and entry doors. Frequently assumed by the base building and excluded by it.
Demising walls. Who builds them, to what height, and finished on which side.
Mechanical distribution beyond the main. The base building brings capacity to the boundary. Ductwork inside the premises is tenant work, and the transition point is rarely drawn.
Electrical panel and metering. Whether the panel is in the base building scope and whether the tenant meter is landlord supplied.
Sprinkler drops. The main is base building. The drops follow the tenant layout, which does not exist yet.
Ceiling grid and lighting. Delivered or not, and if delivered, then discarded by most tenants and paid for twice.
Restroom finishes within the premises. Base building on some deals, tenant on others, and almost never stated explicitly.
A worked example
Illustrative figures. Not taken from any client project and not a quotation.
A commercial building with 62,000 square feet of leasable space. The lease template grants a tenant improvement allowance of $65 per square foot, so a total exposure of roughly $4.03 million if the building fully lets on those terms.
The base building construction scope delivers open slab, capped utilities at the boundary and no demising walls. The lease exhibit describes delivery as warm shell with demising walls in place and a distributed sprinkler main.
The demising walls across the building are $310,000. The additional sprinkler distribution to satisfy the exhibit is $190,000. Neither is in the construction contract.
Separately, the base building includes a ceiling grid throughout at $240,000. Three of the first four tenants remove it.
Net exposure created entirely by the two documents disagreeing: roughly $740,000 on a building where the allowance itself was market rate and defensible.
Why this is worse on a speculative building
Where tenants are signed before construction, the delivery condition is negotiated against a known fit out and the two documents tend to converge.
On a speculative building nobody knows who the tenant is, so the lease exhibit is written generically and the construction scope is written to a budget. There is no forcing function to reconcile them, and the reconciliation happens one lease at a time, after the base building is built.
At that point every discrepancy is a change order or a concession. The base building cannot economically add demising walls after the slab is finished and the space is being marketed, and a tenant who was promised a condition in a lease exhibit will hold you to it.
The cheapest moment to reconcile is before the base building scope is awarded, when moving an item from one side of the line to the other costs a scope revision rather than a mobilization.
That reconciliation is an afternoon with two documents and somebody who reads both, which is a small exercise against a seven figure exposure on a building of any size.
What to do before you sign
- Put the lease delivery exhibit and the base building scope of work side by side, line by line.
- Resolve the seven items above explicitly, in writing, before the base building package is awarded.
- State the delivery condition in the construction contract using the same words the lease exhibit uses.
- Check whether anything in the base building will be removed by a typical tenant, and delete it.
- State the allowance basis: delivery condition, expected use and who manages the work.
- Model the total allowance exposure against full occupancy, not against the first tenant.
- Establish whether unused allowance is retained, converted to free rent, or lost.
Item three is the one that prevents the argument entirely. Two documents that use the same words for the same boundary cannot disagree about it later, and matching the language costs nothing at the point the scope is written.
Item six catches a different error. Owners frequently model the allowance against the first tenant and treat the rest as a future problem, which understates the obligation by a factor of ten on a building of any size. The exposure is the full leasable area multiplied by the rate, discounted for whatever the market lets you hold back, and it belongs in the budget on day one.
Item seven decides whether unspent allowance is money or a gift. On many leases an unused balance simply disappears in the tenant favor, which means a tenant who fits out cheaply has been paid the difference in free rent without anybody deciding to do that. The scope options for reading these two documents against each other are in the review packages.
What we do
We read the lease delivery exhibit against the base building scope of work and list every item that sits in neither or in both, with a dollar figure against each. It is a commercial reading of two documents, not a legal opinion on the lease, which stays with your counsel. The work is part of the constructability and interface review.
Questions people ask
Is a tenant improvement allowance part of the construction contract?
Usually not. The allowance is a lease obligation and the base building is a construction contract. That separation is normal and it is also the reason the boundary between them is frequently described twice, in different words, by people who never compared the two documents.
What is warm shell, exactly?
It has no fixed definition, which is the problem. On one deal it means distributed mechanical and a finished ceiling grid, on another it means capped utilities and a bare slab. The term should never appear in either document without a list of what it includes.
Should the base building include a ceiling grid?
It depends who the tenants will be, and on a speculative building the honest answer is often no. A grid installed for everybody and removed by three tenants out of four is paid for twice, once in the base building and once through the demolition line in the fit out.
