What is a tenant improvement allowance, and what happens if my build-out costs more than the TI?
The short answer
A tenant improvement (TI) allowance is an amount the landlord agrees to contribute toward fitting out the space for the tenant's use, typically stated as a dollar-per-square-foot figure. If the actual construction cost exceeds the allowance, the overrun is generally the tenant's obligation. How the allowance is disbursed — lump sum, progress payments, or reimbursement after completion — affects the tenant's cash flow during build-out. Use-it-or-lose-it deadlines (commonly 6–12 months from lease commencement) and spending restrictions on what the allowance may cover are additional terms that can limit the practical value of the TI. Scan your lease to see the allowance amount, the disbursement method, the deadline, and what happens to overruns before you sign.

What the TI allowance clause usually does
The TI clause states the total allowance available, the conditions for disbursement, what the funds may be used for, and the deadline by which construction must be complete and funds drawn. A commonly seen structure pays the allowance as a reimbursement: the tenant funds construction costs upfront and the landlord reimburses against approved invoices. Other structures involve landlord-managed build-out where the tenant approves plans and the landlord contracts directly with builders. In either case, the allowance amount is typically fixed at lease signing, while actual construction costs are not known until bids come in.
Use-it-or-lose-it provisions are common: if the tenant does not complete the approved build-out and submit for reimbursement within the stated window (often 6 to 12 months after the lease commencement date), unused allowance may be forfeited. Some leases allow unused TI to be applied to rent or converted to additional improvements after the initial window, but this must be expressly stated.
Why people worry
Tenants commonly report signing a lease with a TI allowance based on an early-stage cost estimate, then receiving contractor bids substantially above that estimate once market conditions, material costs, and permitting requirements are known. The overrun belongs to the tenant. A gap between a $50/sq ft allowance and a $90/sq ft actual build-out cost is a real cash obligation that may not have been in the original business plan.
What to look for in your lease
- The TI allowance amount per square foot and the total dollar figure.
- The deadline for completing construction and requesting reimbursement — and what happens to unused funds.
- Whether the allowance covers only construction costs or also soft costs: permits, architect fees, project management.
- The disbursement process — reimbursement after completion, progress payments, or landlord-controlled funds.
- Whether overruns are explicitly assigned to the tenant, and whether the lease addresses what happens if the build-out cannot be completed within the allowance.
Questions to ask before signing
- Ask the landlord for any recent build-out cost data for comparable spaces in the building to calibrate whether the TI will cover expected costs.
- Ask the other party to clarify whether soft costs — permits, architects, and project management — are included in the allowance or are the tenant's separate obligation.
- Confirm the disbursement method and the timeline for receiving funds after submitting invoices.
- Consider having the lease reviewed to confirm the TI terms and what the overrun risk is before committing to the build-out plan.
Why scan instead of guess
The general rule tells you the baseline. Your lease tells you what you’re actually being asked to sign — and the wording is what binds. Dang reads the document and flags the clauses worth reviewing, in plain English.

Common questions
What does 'turnkey' mean compared to a TI allowance?
A turnkey build-out means the landlord delivers a finished space to the tenant's approved specifications at the landlord's cost — the tenant does not manage construction or fund overruns. A TI allowance caps the landlord's contribution; above that amount, the tenant pays. Which structure is used depends on negotiation, and the lease should clearly define which applies.
What if I don't use all of my TI allowance?
Many leases include a use-it-or-lose-it provision: unused TI funds expire after the stated deadline. Some leases allow unused allowance to be applied to rent or future improvements, but that requires an express lease provision. Confirming the TI use-or-lose policy before signing is advisable.
Can I take a higher TI allowance and pay it back through higher rent?
Some landlords structure higher TI as an amortized loan embedded in the rent — the higher monthly cost reflects the build-out contribution being recouped over the lease term. Whether this structure is available and on what terms depends on the landlord and the negotiation.
