What is the average cost of a landlord-funded tenant improvement allowance in 2027?

The commercial deal in plain terms

A tenant improvement allowance — TI, TIA, or simply "the allowance" — is landlord money contributed toward building out a leased space so the tenant can actually occupy it. It is not a gift and it is not free. It is capital the landlord advances against a lease, recovered through rent over the term, and the landlord's underwriting math is straightforward: every dollar of allowance must be earned back inside the lease term at an acceptable return, or the deal does not clear committee.

The mechanics matter because they determine what the "average cost" actually means for whoever is asking. There are at least three different numbers people call the TI allowance, and they are not interchangeable. The first is the headline allowance quoted in the letter of intent, expressed in dollars per rentable square foot. The second is the actual construction cost of the buildout, which is frequently higher than the allowance and leaves the tenant covering the overage out of pocket. The third is the landlord's effective cost after amortization, which is lower in present-value terms than the headline number because the landlord recovers it through the rent stream. When a broker says "we got $80 a foot," they mean the first number. When a CFO asks what the buildout cost, they mean the second. When an asset manager models net effective rent, they mean the third.

The typical structure is a reimbursement, not a check up front. The tenant or the tenant's contractor performs the work, submits draw requests with lien waivers and invoices, and the landlord funds against completed work — often with 5 to 10 percent retainage held until substantial completion and final lien releases. Some landlords instead perform the work themselves under a landlord-build or turnkey arrangement, where the allowance never touches the tenant's bank account and the landlord simply delivers a finished space to an agreed specification. Turnkey deals shift schedule and cost overrun risk to the landlord, which is why landlords price them conservatively and why the specification exhibit becomes the most-negotiated document in the lease.

The economics tie directly to lease term. A common rule of thumb across brokerage practice is that landlords will fund roughly $8 to $15 per square foot of allowance per year of lease term on a standard office deal, subject to the building's business plan and the tenant's credit. That heuristic explains most of the observed variance: a five-year deal supporting $50 a foot and a ten-year deal supporting $100 a foot are not two different markets, they are the same underwriting applied to different durations. It also explains why short-term and month-to-month deals carry essentially no allowance — there is no runway to amortize anything.

Credit quality is the second lever. An investment-grade tenant with a ten-year commitment is financing at the landlord's cost of capital with minimal default probability priced in. A three-person startup with no operating history is not, and the landlord will either shrink the allowance, demand a larger security deposit or letter of credit, or push toward a "landlord work letter" limited to base building conditions — new paint, new carpet, HVAC in working order, code-compliant restrooms — and nothing more.

The anchor point worth remembering: average is a weak statistic here. The distribution is wide, bimodal in some markets, and heavily conditioned on whether the space is first-generation shell or second-generation space with existing improvements. Quoting a single national average without specifying property type, generation, term, and market is how budgets get built wrong.

How the buildout process flows

The path from signed letter of intent to occupied space runs through a sequence that most tenants underestimate by two to four months. Understanding the flow matters because nearly every cost surprise in a TI project traces back to a decision made — or deferred — at one of these gates.

The test fit comes first and it is usually free. Landlords routinely fund a preliminary space plan from their architect at no cost to the tenant, because a test fit is a cheap way to prove the space works and keep a prospect engaged. Take it, but understand that a test fit is not construction documents. It shows walls and desks. It does not show mechanical, electrical, plumbing, or the structural implications of the conference room the CEO wants where a column happens to be.

The work letter is where the money is actually decided. This exhibit defines what the allowance may be spent on, who holds the construction contract, what base building conditions the landlord delivers, how draws are processed, what the construction management fee is, and what happens to unused allowance. Every ambiguity in the work letter becomes a change order later. The single highest-leverage hour a tenant can spend is reading the work letter with a construction attorney or a tenant-side project manager before signing, not after.

Bidding is where the allowance meets reality. Three general contractor bids is standard practice; two is thin and one is not a bid, it is a quote. Bids come back within a range, and the range itself is diagnostic — if three qualified GCs land within eight percent of each other, the drawings are clear. If the spread is thirty percent, the documents are incomplete and somebody is carrying assumptions the others are not. Chasing the low bid on incomplete drawings is the most reliable way to generate change orders.

Permitting and long-lead procurement are the two schedule killers. Municipal plan review timelines vary enormously, from about two weeks in permissive jurisdictions to several months in dense urban markets with historic review, energy code review, or accessibility plan check. Long-lead equipment — rooftop units, electrical switchgear, custom glass, specialty lighting — has run notably longer than pre-2020 norms across the construction sector, and a project that does not release those orders early enough will sit finished-but-unpowered waiting on gear.

Adjacent workflow worth noting: the same draw-and-lien-waiver mechanics govern landlord capital improvements, first-generation shell completion, and even some restaurant and medical fitouts where equipment financing rides alongside the allowance. If you have run one, you can read the others.

Costs per square foot, timelines, and ranges

Here is where the numbers live. Treat every figure below as a planning range, not a quote, and re-underwrite against local bids.

Office, second-generation space. The most common scenario. A tenant takes space that was previously occupied, keeps most of the existing walls, ceilings, and mechanical distribution, and refreshes finishes and reconfigures a portion of the plan. Allowances commonly land in the $40 to $80 per square foot band, with $50 to $60 a frequent midpoint for a standard five-to-seven-year deal in a Class B building. Actual construction cost for a light refresh — paint, carpet, minor demising, some new glass fronts — often runs $35 to $70, so a well-negotiated allowance can genuinely cover the work.

Office, higher-end or first-generation. Class A towers, full-floor users, and shell space that has never been built out sit higher. Allowances of $80 to $130 per square foot appear on long-term deals with strong tenants, and construction costs for a full buildout with new mechanical distribution, ceilings, lighting, millwork, glass fronts, and a real reception experience can run $100 to $200 or beyond in expensive coastal markets. High-design or executive-suite work has no meaningful ceiling — it is a design budget, not a construction average.

Retail. Landlords typically contribute far less, often $10 to $40 per square foot, and frequently structure the contribution as a vanilla shell delivery plus a modest cash allowance. Retail tenants carry heavy trade-fixture and equipment costs the landlord will not fund. Restaurant buildouts are their own category — grease interceptors, hood systems, gas service, and enhanced ventilation push total project costs well above general retail, and the landlord's share rarely keeps pace.

Industrial and warehouse. The lowest allowances by a wide margin, commonly $2 to $15 per square foot across the full building footprint, because most of the leased area is clear-span warehouse that needs almost nothing. The office portion of an industrial building — often 5 to 15 percent of the total square footage — carries a much higher per-foot cost, so landlords sometimes quote the office component separately at office-like rates.

Medical and lab. Substantially higher than general office. Medical office buildouts require plumbing to exam rooms, lead-lined walls for imaging, medical gas in some cases, and enhanced electrical. Lab space adds fume hoods, specialized exhaust, backup power, and vibration considerations. Allowances are correspondingly larger but almost never cover the full cost, and tenants routinely fund a large share directly or through landlord-provided amortized additional TI.

Timelines. For a typical office project: test fit two to four weeks, construction documents four to eight weeks, bidding three to four weeks, permitting two weeks to several months depending on jurisdiction, construction eight to sixteen weeks for a straightforward refresh and four to eight months for a full buildout. A realistic end-to-end planning horizon for a mid-size office deal is five to nine months from LOI to occupancy, and tenants who sign a lease with a hard rent commencement date sixty days out are signing up to pay rent on a construction site.

Amortized additional TI. When the buildout exceeds the allowance, the standard remedy is landlord-funded excess repaid through the rent at an interest rate. Rates in the high single digits to low double digits are common, and the amortization runs the remaining term. This is real financing and belongs in the tenant's cost of capital analysis — it is often more expensive than the tenant's own bank debt, and sometimes cheaper than the tenant's equity. Run the comparison rather than reflexively accepting it.

Free rent as a substitute. Landlords trade allowance against free rent, and the exchange rate is not one for one. A landlord may prefer granting months of abatement over writing a construction check because abatement costs nothing today and preserves capital. A tenant who does not need a large buildout should push the concession package toward abatement; a tenant taking raw space should push toward allowance. Model both against net effective rent rather than negotiating each in isolation.

Where budgets and schedules slip

The gap between the allowance and the final invoice is where tenant improvement projects earn their reputation. The failure modes are consistent and largely preventable.

Soft costs consuming the allowance. Many work letters permit the allowance to be applied to architecture, engineering, permits, project management, and sometimes furniture, cabling, and moving. This sounds generous and often is, but soft costs can consume fifteen to twenty-five percent of the allowance before a single wall goes up. If the allowance is $60 and soft costs eat $12, the construction budget is $48. Model soft costs explicitly rather than discovering them.

Construction management fees. Landlords commonly charge a supervision or construction management fee, frequently in the range of two to five percent of hard costs, deducted from the allowance. Some landlords stack a general conditions charge on top. This is negotiable, particularly for larger tenants, and is often the easiest line item to reduce because it is pure margin rather than cost.

Base building deficiencies. The single largest source of unbudgeted expense. A tenant plans a $50-per-foot refresh and then discovers the existing HVAC does not meet current code, the electrical service cannot support the density, the restrooms are not accessibility-compliant, or asbestos abatement is required in the ceiling plenum. The lease should assign base building compliance to the landlord explicitly and in writing, delivered in code-compliant condition as of the delivery date. Without that language, the tenant pays.

Code triggers. Renovation work above certain thresholds triggers upgrade requirements that were not required when the building was built — sprinkler coverage, egress modifications, energy code compliance for lighting and mechanical, accessibility path-of-travel improvements. A small scope can trip a large obligation. Ask the architect early and specifically whether the planned scope triggers anything.

Unused allowance evaporating. Most work letters state that unused allowance is forfeited. Some permit a portion to convert to rent credit, often capped. Negotiate for conversion if there is any chance of underspending, and understand that landlords resist it because forfeiture is a real economic benefit to them.

Draw and funding friction. Landlords fund against completed work with conditional and unconditional lien waivers from the general contractor and every subcontractor and material supplier above a threshold. Missing paperwork stops funding. Tenants who front the cash and wait on reimbursement carry working capital they did not plan for, and a thirty-to-sixty-day funding lag on a large project is meaningful.

Change orders. The universal cause is incomplete drawings. The second cause is scope creep after pricing. A five to ten percent contingency on hard costs is the minimum defensible reserve; ten to fifteen percent is prudent on older buildings or aggressive schedules.

Rent commencement mismatch. If rent starts on a fixed calendar date rather than on substantial completion or delivery, every day of permitting delay is a day of rent on unusable space. Tie commencement to delivery of the premises in the required condition, with landlord-caused-delay provisions that toll the clock.

Adjacent scenario — subleases and assignments. A subtenant taking space from a sublandlord generally gets no allowance at all, because the sublandlord has no capital interest in improving space it is trying to shed. Subleases price lower per foot precisely because the improvement package is absent. That trade is often good value for a tenant that can live with the existing configuration.

Decision framework

The practical question is rarely "what is the average" but "what should I ask for, and what will I actually spend." This framework sequences the decision.

Work the framework in order. Scope first, because a refresh and a buildout are different orders of magnitude and no negotiation strategy survives an undefined scope. Get a rough order-of-magnitude number from a contractor or tenant-side project manager on the actual space before the LOI is finalized — an ROM costs nothing and reframes the entire negotiation.

Term second, because term determines what the landlord can fund. If the ROM says $95 a foot and the tenant wants a five-year deal, the arithmetic will not work and the choice is to extend the term, reduce the scope, or find a space that needs less work. Pretending otherwise wastes months.

Then compare financing. Amortized additional TI at ten percent is expensive money for a company with a bank line at seven, and cheap money for a company whose alternative is dilutive equity. This is a finance decision, not a real estate decision, and the CFO should own it.

Finally, protect the execution. Lock the work letter terms, bid properly, carry contingency, and tie rent commencement to delivery. Most of the value in a tenant improvement negotiation is captured in the work letter, not in the headline allowance number, and tenants who win the headline and lose the exhibit routinely end up worse off than tenants who did the reverse.

One broader point on the commercial landscape: allowance levels are a concession, and concessions move inversely with landlord leverage. In soft markets with elevated vacancy, allowances rise along with abatement because landlords compete for occupancy. In tight submarkets they compress toward zero. Any national average is therefore a blend of very different local conditions, and the only number that matters is what comparable deals in the same submarket closed at in the last six to twelve months. Ask the broker for those comps, in writing, before anchoring on any published figure.

Related questions

Does the tenant improvement allowance have to be spent on construction?

Depends entirely on the work letter. Many permit architecture, engineering, permits, and project management. Some allow cabling, security, or furniture. Others restrict the allowance strictly to hard construction costs affixed to the premises. Read the exhibit — the eligible-cost definition is negotiable before signing and immovable after.

What happens to unused allowance?

In most leases it is forfeited to the landlord. Some tenants negotiate the right to convert a portion — often capped at a set dollar amount or percentage — into free rent or a rent credit. Landlords resist this because forfeiture has real value to them, but it is winnable on larger deals.

Is the allowance taxable income to the tenant?

It can be, depending on structure and jurisdiction, and the accounting treatment under current lease standards differs from the tax treatment. Allowances are generally recorded as lease incentives reducing the right-of-use asset and amortized. Consult a tax advisor — structure changes the answer materially.

How does a turnkey buildout differ from an allowance?

In a turnkey, the landlord builds to an agreed specification and delivers a finished space; the tenant never handles the money or the contractor. Overrun risk sits with the landlord. The trade-off is control — the tenant gets less say in finishes and change orders become expensive negotiations.

Do renewals come with allowances?

Usually smaller ones, often $5 to $25 per square foot for a refresh, because the tenant is already in place and the landlord avoids downtime and re-leasing costs. Renewal allowances are frequently underasked — sitting tenants have more leverage than they think, particularly in high-vacancy submarkets.

FAQ

What is the single most common office allowance figure in 2027?

There is no single figure, but $50 to $60 per square foot is a reasonable planning midpoint for a five-to-seven-year second-generation office deal in a typical suburban or Class B urban market. Class A, long-term, and first-generation deals run materially higher — often $80 to $130. Retail and industrial run much lower. Always validate against local comparable transactions rather than a published average, because submarket vacancy moves this number more than any other single variable.

Can I negotiate a larger allowance, or is it fixed?

It is negotiable, and the levers are term length, credit strength, security deposit size, rent rate, and market conditions. Landlords trade allowance against face rent constantly — a tenant willing to accept a higher rental rate can often extract a larger allowance, because the landlord recovers the capital through the rent stream. Model net effective rent across the full term rather than negotiating allowance and rate as separate wins.

Who holds the construction contract, and does it matter?

It matters a great deal. Tenant-held contracts give the tenant control over the contractor, the schedule pressure, and the change order process, but also the risk and the administrative burden. Landlord-held contracts shift administration to the landlord but typically come with a construction management fee and less tenant control. Mid-size tenants usually do better holding the contract with a tenant-side project manager engaged.

How much contingency should I budget above the allowance?

Carry at least five to ten percent of hard costs on a straightforward second-generation refresh with complete drawings, and ten to fifteen percent on older buildings, aggressive schedules, or projects bid off incomplete documents. Add a separate line for soft costs if the work letter permits them against the allowance, since they can consume fifteen to twenty-five percent before construction begins.

What is amortized additional TI and should I take it?

It is landlord financing for the portion of the buildout exceeding the allowance, repaid through increased rent over the remaining term at a stated interest rate, commonly in the high single digits to low double digits. Take it when that rate beats your own cost of capital and you want to preserve cash. Decline it when you can borrow more cheaply — it is a financing decision that belongs to finance, not to real estate.

Why do industrial allowances look so low compared to office?

Because the per-square-foot figure is spread across the entire leased area, and most of an industrial building is clear-span warehouse requiring essentially no improvement. The office component within that building carries office-level costs, but it may represent only a tenth of the footprint. Landlords sometimes quote the office portion separately to make the comparison honest.
