Tenant improvement allowances: what to offer, and what it is really costing you
By the Atlas team. Research and practical guides for commercial landlords and leasing brokers, from the people building tenant-search software.
A tenant improvement allowance is the point where a small landlord most often gives away more than they meant to, because it is discussed in the language of concessions. The tenant asks for help with the build, a number gets agreed in a phone call, and nobody works out what it costs or when it comes back.
Treated properly it is not a concession at all. It is a capital investment with a payback period, and once it is written that way the decision usually answers itself.
The arithmetic that settles it
That comparison is the whole decision. If the unit has been empty for four months and the contribution would sign a strong tenant this month, you are choosing between paying it and paying the cost of vacancy for however many more months the search takes. The vacancy figure is the one from how long a vacancy should take, and it is usually larger than owners expect.
Why it beats a rent reduction
Both close an affordability gap. They are not equivalent afterwards.
- A rent reduction runs for the term. Five years at $500 a month less is $30,000, and it is gone whether or not the tenant needed it after year one.
- It resets your benchmark. The reduced rent is what the next valuation sees, what the renewal negotiates from, and what the neighbouring unit’s tenant will hear about.
- An allowance is a one-off against a real cost. It solves the thing actually blocking the tenant, which is that the build has to be paid for before the business opens and earns anything.
There is also a psychological asymmetry worth using. A tenant experiences an allowance as the landlord investing in their business, and a rent cut as the landlord admitting the space is worth less. The second framing follows you into every later conversation.
How to structure it so it is safe
- Pay on completion, against receipted invoices. Never in advance. The allowance should be reimbursement for work actually done, evidenced.
- Name what it may be spent on. Improvements that stay with the building, such as plumbing, electrical, HVAC, flooring and partitions. Not equipment that walks out of the door with the tenant.
- Tie it to the term. A contribution assumes the rent is collected over the years that repay it, so pair a substantial allowance with a term long enough to earn it back, and consider clawback on early termination.
- Approve the drawings. You are funding work on your asset, and layouts that suit one tenant can make a unit harder to relet.
- Confirm permits and insurance before work starts, and retain a portion until sign-off.
When to refuse
Some allowance requests are a signal rather than a negotiation:
- When the tenant cannot fund the rest of the build. An operator who needs your contribution to cover the whole fit-out is telling you they are undercapitalised, and the risk of a half-finished unit coming back is real. The screening questions in how to qualify a commercial tenant surface this before you get here.
- When the work is entirely tenant-specific. Branded shopfittings and bespoke interiors add nothing to the building the day they leave.
- When the payback exceeds the certain part of the term. An allowance repaid over four years against a lease with a two-year break is an unsecured loan.
The cheaper move, first
Before funding anyone’s fit-out, check that the right operators were ever approached. Allowances get offered most often to whoever finally enquired, which is not the same as the best available tenant, and an operator who genuinely fits the space frequently needs less help because the unit already does most of what they need.
That is the argument for sourcing before discounting. Atlas returns matched businesses with the size each typically takes and the person who signs, so the shortlist is made of operators the unit actually suits, for $200 a month. When an allowance is still the answer, the arithmetic above tells you what it is worth.
Common questions
- What is a tenant improvement allowance?
- A contribution from the landlord toward fitting out the space for the tenant, usually expressed as a sum per square foot and paid on completion against receipted invoices. It is a capital cost to the landlord and is normally recovered through rent over the term.
- Is it better to give a rent reduction or a tenant improvement allowance?
- For most landlords the allowance is better. It is a one-off payment against a specific cost the tenant faces immediately, and it leaves the headline rent intact for valuation and for every future renewal, whereas a rent cut applies for the entire term and resets the benchmark.
