What it means
Commercial space is often let as a shell or in the previous occupier's configuration, and turning it into a usable office, clinic or shop costs real money. The TI allowance is the landlord's share of that cost, negotiated alongside rent, term and rent-free periods as part of the overall deal.
For a growing business this is one of the most valuable items in a lease negotiation, because fit-out is a large upfront cash outflow at exactly the moment a company is committing to years of rent. Winning an extra $10 per square foot on a 10,000 square foot space is $100,000 of capital the tenant does not have to fund.
The allowance is almost never free money. Landlords price it into the rent, so a generous allowance usually comes with a higher headline rate or a longer term, which is why tenants should compare deals on effective rent rather than on either number alone.
Effective rent spreads the total rent over the term after deducting landlord contributions and rent-free months. Payment mechanics matter more than most tenants expect.
The allowance is typically reimbursed after the work is done, against invoices, lien waivers and landlord sign-off on the plans, which means the tenant funds the whole fit-out first and waits weeks or months to be repaid. Some agreements also restrict what qualifies, covering fixed building works but excluding furniture, technology and moveable equipment.
There is an ownership nuance too. Improvements paid for with the allowance usually become the landlord's property and stay in the building at the end of the lease, and for accounting purposes the tenant normally capitalises the fit-out as a leasehold improvement while treating the allowance as a lease incentive spread over the term.
The exact treatment depends on the accounting standard being applied, so it is worth agreeing with your auditor early.
In practice
Real-world examples.
Example
A dental practice takes 3,500 square feet in a suburban centre with a $75 per square foot allowance, giving $262,500 towards plumbing, lead-lined walls and surgery fit-out. The specialist works cost $340,000, so the practice funds the $77,500 difference from a small equipment loan.
Example
A technology firm negotiates a lower allowance of $30 per square foot in exchange for a rent reduction of $3 per square foot across a seven-year term on 20,000 square feet. The lower allowance costs $600,000 upfront but the rent saving is worth $420,000, so the finance director models both against the firm's cost of capital before deciding.
Example
A landlord re-letting a floor previously occupied by a call centre offers a large allowance of $85 per square foot because the space needs stripping back before any tenant can use it. The incoming tenant treats the allowance as a lease incentive and spreads it across the lease term in its accounts rather than recognising it as income on day one.
Think of it
“TI allowance is the abbreviation for tenant improvement allowance-buildout money.
Formula
Calculation
Total TI allowance = allowance per square foot x rentable square feet
A professional services firm signs a 10-year lease on 10,000 rentable square feet at a base rent of $40 per square foot per year, with a tenant improvement allowance of $50 per square foot.
The allowance is $50 x 10,000 = $500,000. The firm's contractor prices the full fit-out, including partitions, meeting rooms, a kitchen and cabling, at $650,000, so the tenant must fund $650,000 - $500,000 = $150,000 itself, plus furniture and technology, which the lease excludes.
Now check the deal on effective rent. Annual rent is $40 x 10,000 = $400,000, and over the 10-year term that is $400,000 x 10 = $4,000,000. Deducting the $500,000 allowance gives $4,000,000 - $500,000 = $3,500,000 of net rent, or $3,500,000 / 10 = $350,000 a year. That is an effective rent of $350,000 / 10,000 = $35 per square foot, against a headline of $40.Case study
Seen in the real world.
Halcyon Rivers Consulting is an illustrative, fictional advisory firm that moved from 4,000 to 10,000 square feet after winning a large client. It negotiated hard on rent, agreeing $40 per square foot with a $50 per square foot allowance, and treated the resulting $500,000 as though it would cover the whole move.
Two assumptions broke. The fit-out came in at $650,000 because the firm wanted individual offices and additional meeting rooms, and the allowance excluded $180,000 of furniture and audio-visual equipment. Worse, the landlord reimbursed only on completion and sign-off, so Halcyon carried $650,000 of contractor payments on its own balance sheet for four months before the $500,000 arrived.
In this fictional example the firm survived by drawing on a revolving facility, but the finance director rewrote the company's lease checklist afterwards. Future negotiations would ask for staged reimbursement against milestones, a written list of qualifying costs, and a separate budget line for everything the allowance does not cover.
Watch out
Common mistakes.
- Treating the TI allowance as free money rather than a cost the landlord recovers through higher rent over the term.
- Assuming the allowance is paid upfront, when most leases reimburse only after the work is finished and approved, creating months of cash strain.
- Budgeting the fit-out at the allowance amount and forgetting excluded items such as furniture, servers, signage and moving costs.
Questions
People also ask.
How much TI allowance is normal?
It varies widely by market, building quality and lease length, but a longer term and a stronger covenant will always support a larger contribution, so the number is negotiated rather than standard.
Who owns the improvements at the end of the lease?
Fixed works normally become the landlord's property and remain in place, which is one reason landlords are willing to fund them in the first place.
How is a TI allowance treated in the accounts?
The tenant generally capitalises the fit-out as a leasehold improvement and treats the allowance as a lease incentive spread over the lease term, though the precise mechanics depend on the applicable standard.
