Tenant Improvement Allowances in Commercial Real Estate: Market Standards, Disbursement Methods, and Effective Rent Impact

Key Takeaways

What a Tenant Improvement Allowance Is

A tenant improvement allowance is the dollar amount a landlord provides, typically expressed per rentable square foot (RSF), to fund the buildout or renovation of a commercial space for a specific tenant. The TI allowance is negotiated as part of the lease and memorialized in the lease agreement, usually in the work letter or tenant improvement exhibit. The allowance covers interior construction: partitions, flooring, ceilings, lighting, HVAC modifications, electrical and data wiring, plumbing, and finishes. It does not typically cover furniture, fixtures, equipment (FF&E), signage, or technology infrastructure, though these exclusions vary by lease.

The TI allowance exists because commercial space is rarely delivered in a condition that matches a specific tenant's operational needs. A law firm's layout differs from a technology company's open-plan configuration, which differs from a medical practice's exam-room-and-waiting-area requirement. Rather than building out every possible configuration on spec, landlords provide a cash contribution and let the tenant (or the landlord, in a turnkey arrangement) customize the space. The landlord recovers the TI cost through the rent structure, either by amortizing it into a higher face rent or by pricing the lease to reflect the TI as a below-the-line concession in the effective rent calculation.

One point that tenants sometimes misunderstand: the landlord owns the improvements. Once TI-funded construction is complete, the partitions, built-in cabinetry, upgraded HVAC, and other permanent improvements become part of the building. When the lease expires, the tenant vacates and the improvements stay. Some leases include a restoration clause requiring the tenant to remove certain improvements at lease end, but the default under most institutional leases is that TI-funded improvements belong to the landlord. This ownership structure is what allows the landlord to depreciate the improvements and is one reason TI allowances differ from a simple cash rebate.

The relationship between TI and rent is not linear, but it is directional. Higher TI generally means higher face rent, because the landlord amortizes the TI cost into the rental stream. A landlord offering $75/SF TI on a 10-year lease at 7% cost of capital is embedding approximately $10.68/SF/year of TI recovery into the rent. The tenant sees a larger buildout budget. The landlord sees a higher gross rent that includes capital recovery. The effective rent, which nets out all concessions, is where the two perspectives converge.

TI Allowance Ranges by Property Type

TI allowances vary widely by property type, building class, market, lease term, tenant credit quality, and whether the space is first-generation (never previously occupied) or second-generation (previously built out by a prior tenant). A second-gen space where the prior tenant's layout is usable may require minimal TI. A first-gen shell or a space requiring full demolition and reconstruction commands a much higher allowance.

The following ranges reflect 2026 market conditions across major U.S. markets. These are negotiated ranges, not fixed standards. Individual transactions regularly fall outside these bands depending on deal-specific factors. For current market-specific data, Cushman & Wakefield's tenant improvement guides publish metro-level TI benchmarks annually.

Several factors push TI toward the upper end of these ranges. Longer lease terms give the landlord more months over which to amortize the cost, making a higher TI economically viable. Credit tenants (investment-grade or publicly traded companies) reduce the landlord's risk of a lease default before the TI is fully recovered, which supports a more generous allowance. First-generation space that has never been built out requires more work than a second-generation space where usable improvements remain from the prior tenant. And competitive markets with high vacancy rates force landlords to offer larger concessions to attract tenants, with TI being one of the primary levers alongside free rent.

At the lower end, shorter lease terms compress the amortization window and limit the TI the landlord can offer without destroying effective rent economics. Smaller tenants with limited credit profiles increase the landlord's risk exposure. And in tight markets with low vacancy, landlords have less incentive to offer generous concessions because tenant demand exceeds available supply. As Tyler Cauble's 2026 market guide notes, the landlord is always baking TI cost back into the rent. A higher allowance means the tenant is financing the buildout through the lease, not receiving free money.

One additional factor that practitioners frequently underweight: construction cost escalation. TI allowances are negotiated months before construction begins. If material and labor costs increase between lease execution and buildout completion, the tenant bears the excess. In markets where construction costs are rising 3% to 5% annually, a $75/SF TI negotiated in Q1 may cover only $70/SF of purchasing power by the time construction begins in Q3 or Q4. Sophisticated tenants build a cost escalation buffer into their TI ask, typically 5% to 10% above the current-dollar estimate.

Three Disbursement Methods

The disbursement method in the work letter controls how TI dollars move from the landlord's balance sheet to the contractor's invoices. Three methods are standard in institutional leasing: lump sum, draw schedule, and turnkey. Each allocates cost, risk, timeline control, and administrative burden differently. The right method depends on the tenant's construction management capability, the landlord's risk tolerance, and the property type's institutional norms.

Lump Sum

Under a lump-sum arrangement, the landlord pays the full TI allowance to the tenant as a single payment, typically at lease commencement or within 30 days after the tenant opens for business. The tenant manages the entire construction process: hiring the general contractor, selecting subcontractors, obtaining permits, overseeing the buildout, and paying all invoices. The TI check arrives as a lump sum, and the tenant allocates it as they see fit.

The lump-sum method gives the tenant maximum flexibility and control. The tenant chooses the GC, negotiates subcontractor pricing, manages the construction timeline, and keeps any savings if the buildout comes in under budget. For tenants with in-house construction management capability or strong GC relationships, this is often the preferred approach.

For the landlord, the lump-sum method is administratively simple: write one check, file the receipt, move on. The risk is that the tenant may pocket the savings rather than investing in high-quality improvements that enhance the building's long-term value. Some landlords mitigate this by requiring the tenant to submit receipts proving that the TI was spent on approved improvements, with any unspent balance returned to the landlord or applied as a rent credit. Others accept that risk as the cost of a clean process.

Draw Schedule (Reimbursement)

The draw schedule method is the institutional standard for office and medical office leases. Under this arrangement, the tenant manages construction but the landlord reimburses invoices as the work progresses, rather than paying the full amount upfront. The work letter specifies the documentation required for each draw: contractor invoices, lien waivers (partial and final), architect's or construction manager's certification of completion for the work covered by the draw, and proof that the work conforms to the landlord-approved plans and specifications.

A typical draw process works as follows. The tenant submits a draw request to the landlord with supporting documentation. The landlord (or the landlord's construction manager) reviews the request, inspects the work in progress, and approves or rejects the draw within a specified period, usually 30 to 45 days. Approved draws are funded by wire transfer or check. The process repeats monthly or at agreed milestones until the allowance is fully disbursed or the buildout is complete. Most work letters allow 3 to 6 draws over the construction period.

The draw schedule protects the landlord by ensuring that TI dollars are spent on actual improvements, that the work meets quality standards, and that lien waivers are collected at each stage to prevent mechanic's liens from attaching to the property. It protects the tenant by providing periodic funding rather than requiring the tenant to self-finance the entire buildout and wait for reimbursement at the end. The tradeoff is administrative complexity: each draw requires documentation, review, and approval, which adds 2 to 4 weeks of processing time to the construction cash flow cycle. Tenants who rely on draw funding to pay contractors need to plan for this delay in their construction budgets.

Turnkey

In a turnkey arrangement, the landlord manages the entire buildout. The tenant provides design specifications (usually through the landlord's approved architect), and the landlord hires the GC, manages construction, handles permitting, and delivers the space to the tenant in move-in condition. The TI allowance is applied internally by the landlord against the construction costs. The tenant never handles the cash.

Turnkey is common in institutional portfolios where the landlord has in-house construction management, existing GC relationships, and the purchasing power to negotiate favorable subcontractor pricing. Large REITs and institutional owners often prefer turnkey because it gives them control over the quality of improvements installed in their building, ensures compliance with building standards and fire/life-safety codes, and allows them to manage the construction timeline to coordinate with other building systems work.

The risk for the tenant is loss of control. The tenant cannot choose the GC or subcontractors, may have limited visibility into construction costs, and has less ability to manage the construction timeline. If the landlord's construction process runs over budget, the tenant may be asked to cover the excess. If the landlord's timeline slips, the tenant may not have contractual remedies beyond a delayed-delivery rent abatement. Tenants who choose turnkey should negotiate a guaranteed maximum price (GMP), a delivery date with rent abatement for delays, and approval rights over the GC and major subcontractors.

Effective Rent and NPV Impact

Face rent (sometimes called asking rent or gross rent) is the headline number in a lease proposal. It is what the tenant pays per square foot per year before accounting for concessions. Net effective rent (NER) is the landlord's actual economic return after deducting all concession costs: TI amortization, free rent periods, and leasing commissions. The gap between face rent and NER is the concession cost, and it can be substantial. On a typical Class A office lease with a competitive concession package, the NER may be 25% to 35% below the face rent.

The formula, as described in Wall Street Prep's net effective rent guide, deducts amortized concession costs from face rent on a per-square-foot, per-year basis:

Why does TI amortization use an interest rate rather than simple straight-lining? Because the TI represents a capital outlay by the landlord at lease commencement. The landlord is investing $750,000 (in a 10,000 SF space at $75/SF TI) at time zero and recovering it over the lease term through rent. The time value of that capital investment means the annual recovery charge is higher than simple division would suggest. At 7% cost of capital over 10 years, the annual capital recovery on $750,000 is $106,843, or $10.68/SF. Simple straight-lining would be $75/SF divided by 10 years = $7.50/SF/year. The difference, $3.18/SF/year, is the landlord's cost of carry on the TI capital.

Consider a concrete example. A 10,000 RSF Class A office lease with the following terms:

• Face rent: $55.00/SF/year NNN
• TI allowance: $75/SF ($750,000 total)
• Free rent: 6 months
• Lease term: 10 years (120 months)
• Leasing commission: $165,000 total (industry standard for this deal size)
• Landlord's cost of capital: 7%

Effective rent calculation:

• TI amortization: $750,000 amortized at 7% over 10 years = $106,843/year = $10.68/SF/year
• Free rent (straight-lined): 6 months of $55/SF/year = $27,500/SF total, spread over 10 years = $2.75/SF/year
• Leasing commission (straight-lined): $165,000 / 10 years / 10,000 SF = $1.65/SF/year
• Net effective rent: $55.00 - $10.68 - $2.75 - $1.65 = $39.92/SF/year

The landlord retains 72.6% of face rent after concessions. The remaining 27.4% covers TI capital recovery, free rent cost, and broker compensation. This erosion is the cost of leasing the space, not a loss. A buyer or appraiser capitalizing rental income should use NER, not face rent, when estimating property value.

The NPV lens adds another layer. Rather than straight-lining concession costs, an NPV-based effective rent calculation discounts all landlord cash flows (rent receipts minus concession outlays) to present value at the landlord's discount rate. The NPV approach captures the timing of cash flows more precisely. The TI outlay occurs at time zero. Rent receipts begin after the free rent period. Leasing commissions are paid at lease execution. The NPV of the landlord's net cash flow stream, divided by the present value of one dollar per SF per year over the lease term, yields the NPV-adjusted effective rent. This figure is typically lower than the simple straight-line NER because the large upfront outlay (TI + LC) is not offset by early rental income (free rent period). For the example above, the NPV-adjusted NER at a 7% discount rate is approximately $38.10/SF, about $1.82 below the straight-line NER.

ASC 842 Accounting Treatment

The accounting treatment of tenant improvement allowances under ASC 842 (the FASB lease accounting standard effective since 2019) depends on two questions. First, who owns the improvements? Second, when is the allowance received?

Ownership Determination

Under ASC 842, leasehold improvements are classified as either lessee assets or lessor assets based on who controls the underlying work and who retains the improvements at lease end. If the improvements are specific to the lessee, not required by the lease, and cannot reasonably be used by a subsequent tenant, the improvements are a lessee asset. The lessee capitalizes the construction cost as property, plant, and equipment (PP&E) and depreciates it over the shorter of the useful life or the remaining lease term. In this case, the TI allowance received from the landlord is a lease incentive that reduces the lessee's right-of-use (ROU) asset.

If the improvements are required by the lease, benefit the landlord or future tenants, and revert to the landlord at lease termination, the improvements are a lessor asset. The landlord capitalizes and depreciates the improvements. The TI allowance is the funding mechanism for the landlord's own asset, and no lease incentive adjustment is needed on the lessee's books.

Most institutional office leases produce lessee-owned improvements. The tenant designs the space for its specific operational needs, the improvements are too specialized for a subsequent tenant, and the lease either allows removal or requires restoration. The TI allowance in this common scenario is a lease incentive under ASC 842.

Lease Incentive Accounting: Lessee Side

When the TI allowance is classified as a lease incentive, the accounting treatment depends on timing. As detailed in FinQuery's ASC 842 guide on tenant improvement allowances, the treatment differs based on when the incentive is received relative to lease commencement.

TI received at or before lease commencement. The TI allowance reduces the initial measurement of the ROU asset. The lease liability is unaffected because the TI does not change the future lease payment obligations. The lessee records the ROU asset at a lower initial value, which results in lower straight-line lease expense over the lease term. The effect is equivalent to the landlord subsidizing the lessee's lease cost. In journal entry form:

At commencement: Dr. ROU Asset (net of TI incentive), Dr. Cash (TI received), Cr. Lease Liability (PV of future lease payments).

TI received after lease commencement. If the TI will be received in the future (for example, reimbursed against draws during a 6-month construction period after lease commencement), the expected TI is included as a reduction of lease payments in the lease liability calculation at commencement. Both the ROU asset and the lease liability reflect the anticipated TI. As draws are submitted and reimbursed, the receivable is settled. The RSM technical guide on lessee accounting for tenant improvements provides worked journal entry examples for both the commencement-date and post-commencement scenarios.

Lessor Side

For the landlord (lessor), the TI allowance is part of the lease's total consideration. Under ASC 842, the lessor treats the TI as a lease incentive that is netted against rental revenue over the lease term on a straight-line basis. If the improvements are lessor-owned, the landlord capitalizes them and depreciates them. If the improvements are lessee-owned, the landlord recognizes the TI outlay as a reduction of rental income over the term.

The straight-line treatment means the landlord's GAAP rental income in each period equals the total lease consideration (aggregate rent minus TI and other incentives) divided by the number of periods. Face rent in the lease may escalate 2% to 3% annually, but GAAP straight-line rent is level. The TI outlay reduces the total consideration, which reduces the straight-line amount in every period.

Worked Example: 10,000 SF Office Lease

A 10,000 RSF Class A office lease with a $75/SF TI allowance shows how TI flows through both the tenant's occupancy cost model and the landlord's effective rent pro forma.

Deal Terms

Tenant Perspective: Total Occupancy Cost

The tenant's out-of-pocket buildout cost is the excess above the TI allowance: $820,000 actual cost minus $750,000 TI = $70,000 out of pocket ($7.00/SF). This is the tenant's capital contribution to the buildout.

The tenant's total occupancy cost over the lease term includes base rent (after free rent), operating expense pass-throughs (excluded from this NNN example since the tenant pays them directly), and the out-of-pocket buildout excess. With 3% annual escalations starting at $55.00/SF in Year 1 and 6 months of free rent:

Total base rent over 10 years (with free rent): approximately $6,115,000. Add the $70,000 out-of-pocket buildout excess, and the tenant's total occupancy cost for base rent plus buildout is approximately $6,185,000, or $61.85/SF/year on a straight-line basis. The tenant's effective occupancy cost per year is the sum of the straight-lined base rent and the amortized buildout excess.

Landlord Perspective: Net Effective Rent

The landlord's economics look different. The landlord's gross receipts are the same $6,115,000 in total rent. But the landlord's costs include:

• TI outlay: $750,000 at lease commencement (or over months 1-4 via draws)
• Leasing commission: $165,000 at lease execution
• Free rent cost: $275,000 in forgone rent (6 months at $55.00/SF)

Total concession cost: $1,190,000 ($119.00/SF). The landlord invested $915,000 in upfront cash (TI + LC) and gave away $275,000 in rent. Straight-line NER: ($6,115,000 - $1,190,000) / 10 years / 10,000 SF = $49.25/SF? No. The straight-line approach requires computing concession costs differently.

The correct method deducts each concession cost on its own amortization basis:

• TI amortization at 7% over 10 years: $10.68/SF/year
• Free rent straight-lined: $2.75/SF/year
• LC straight-lined: $1.65/SF/year
• NER = $55.00 - $10.68 - $2.75 - $1.65 = $39.92/SF/year

This $39.92/SF is the figure that matters for asset valuation. If an appraiser caps the NER at a 6.5% cap rate, the implied value attributable to this lease is $39.92/SF / 0.065 * 10,000 SF = approximately $6,142,000. If the appraiser mistakenly caps the face rent, the implied value would be $55.00 / 0.065 * 10,000 = $8,462,000. The $2.3 million difference is the capitalized value of the concession package. This is why effective rent matters: it is the rent that generates asset value, and it is the rent the next buyer will inherit.

Comparing Two Proposals with Different TI/Rent Combinations

Tenants and landlords often compare proposals that bundle TI and rent differently. Consider two proposals for the same 10,000 RSF space:

At first glance, Proposal A appears more expensive ($55/SF vs $50/SF face rent). But the TI and free rent packages are very different. Computing the NER for each:

• Proposal A NER: $55.00 - $10.68 (TI) - $2.75 (free rent) - $1.65 (LC) = $39.92/SF
• Proposal B NER: $50.00 - $5.70 (TI at $40/SF amortized at 7% over 10 yrs) - $1.25 (3 months free rent) - $1.50 (LC) = $41.55/SF

Proposal A, despite its higher face rent, delivers a lower NER ($39.92 vs $41.55) because the higher TI allowance more than offsets the rent premium. The tenant who selects Proposal B based solely on face rent comparison is making a $1.63/SF/year mistake, which compounds to $163,000 over the 10-year term for a 10,000 SF space. This is why effective rent analysis, not face rent comparison, is the institutional standard for evaluating lease proposals.

Negotiation Tactics

TI interacts with face rent, free rent, lease term, escalation rate, renewal options, and early termination provisions. Skilled negotiators on both sides treat TI as one element of a multi-variable optimization.

Tenant-Side Tactics

Anchor to actual construction costs. Before negotiating TI, obtain competitive bids from at least two general contractors for the planned buildout. A space plan from an architect and a GC budget estimate give the tenant a defensible basis for the TI ask. Asking for $75/SF TI without a construction budget is negotiating blind. Presenting a detailed budget that demonstrates $82/SF in actual costs justifies a $75/SF ask and signals to the landlord that the tenant has done the homework.

Leverage competing proposals. TI negotiation is most effective when the tenant has genuine alternatives. A tenant negotiating with only one landlord has limited leverage. A tenant with two or three competing proposals can use the best TI offer from one landlord to improve the terms from another. The competing proposal does not need to be identical in space or location; it needs to be a credible alternative that the tenant would actually accept.

Negotiate the TI floor and the unused TI provision. The TI floor is the minimum allowance the landlord will provide regardless of actual buildout costs. The unused TI provision governs what happens to TI dollars that the tenant does not spend on construction. Some leases allow the tenant to apply unused TI toward rent abatement (reducing the first several months of rent). Others require the tenant to forfeit unused TI. A tenant who expects the buildout to come in under the TI amount should negotiate for unused TI to convert to rent credit. This effectively increases the total concession package.

Consider the amortization rate. Two TI offers of $75/SF may produce different NER results if the landlords are using different amortization rates to embed the TI cost into rent. Ask the landlord what cost of capital they are using for TI amortization. A landlord using 8% will embed a higher capital recovery charge into rent than one using 6%, which means the face rent in the first scenario includes more TI recovery cost and the effective rent difference between the two proposals is smaller than the face rent difference suggests.

Landlord-Side Tactics

Cap TI with a guaranteed maximum price. Rather than committing to a fixed TI amount and absorbing any construction overruns, landlords can cap TI at a GMP based on the approved space plan and competitive GC bids. If the buildout exceeds the GMP, the tenant pays the excess. This protects the landlord from construction cost risk while still providing the tenant with a defined budget.

Include a TI recapture clause. A TI recapture clause requires the tenant to repay a portion of the unamortized TI if the tenant terminates the lease early, defaults, or assigns the lease. The recapture amount typically declines ratably over the lease term. For example, on a 10-year lease with $75/SF TI, the recapture amount in Year 3 might be 70% of the original TI ($52.50/SF). By Year 7, it might be 30% ($22.50/SF). By Year 10, it is zero. This clause protects the landlord's TI investment in the event that the lease terminates before the TI is fully amortized through rent.

Tie TI to lease term length. Offer a TI schedule that increases with lease term. A 5-year term gets $40/SF. A 7-year term gets $55/SF. A 10-year term gets $75/SF. This structure incentivizes the tenant to commit to a longer term, which gives the landlord more months to amortize the TI cost and reduces rollover risk. It also prevents the situation where a tenant negotiates a high TI on a short lease, leaving the landlord underwater on the TI investment if the tenant does not renew.

Require competitive bidding for construction. In draw schedule and turnkey arrangements, landlords should require the tenant (or their own construction manager) to obtain at least three competitive bids for the GC contract. Competitive bidding reduces the risk that construction costs are inflated and ensures that TI dollars are spent efficiently. Some landlords include a right-to-audit clause in the work letter, giving them the ability to review construction invoices and contractor markups.

Common Mistakes Practitioners Make

1. Comparing proposals on face rent alone. Face rent is the headline number, but it tells you nothing about the total economics of the lease. A $55/SF lease with $75/SF TI and 6 months of free rent has a very different effective rent than a $50/SF lease with $40/SF TI and 3 months of free rent. Practitioners who rank proposals by face rent without computing NER will systematically select the wrong deal. Run the effective rent calculation for every proposal before comparing them.

2. Ignoring the landlord's amortization rate. TI amortization at 6% versus 8% produces different capital recovery charges and therefore different effective rents, even when the TI amount and face rent are identical. The amortization rate is rarely disclosed in the lease itself because it is the landlord's internal cost of capital, not a negotiated term. But it drives the economics of the deal. When comparing proposals from different landlords, ask each landlord what rate they are using for TI recovery, or back into it from the rent structure.

3. Failing to negotiate unused TI provisions. If the buildout comes in under budget, the unused TI balance sits in a gray area. Some leases require the tenant to forfeit unused TI. Others allow conversion to rent credit. Others are silent on the topic. Leaving this provision unaddressed invites disputes. Negotiate the treatment of unused TI explicitly in the work letter, ideally specifying that unused TI converts to rent abatement applied to the first months of the lease term.

4. Missing the construction cost escalation window. TI is negotiated at lease execution but construction may not begin for 3 to 6 months. If construction costs are rising, the real purchasing power of the TI allowance declines between negotiation and buildout. A $75/SF TI negotiated in January that buys $75/SF of construction in January may only buy $71/SF in June if costs have risen 5%. Experienced tenants build a 5% to 10% cost escalation buffer into the TI ask or negotiate a construction start deadline with a TI escalation clause.

5. Overlooking TI recapture exposure. Many institutional leases include a TI recapture clause that requires the tenant to repay unamortized TI upon early termination. Tenants who negotiate a high TI on a 10-year lease and then need to exercise an early termination option in Year 4 may face a substantial recapture liability. Review the recapture schedule and model the exposure before committing to a high-TI, long-term deal. If the business plan involves any possibility of early exit, negotiate a reduced recapture schedule or a cap on the recapture amount.

6. Treating TI as free money. TI is not a gift from the landlord. It is a capital investment that the landlord recovers through the rent structure. A tenant who views TI as a subsidy rather than an embedded financing cost will overweight TI in proposal comparisons, accept higher face rents without questioning the amortization math, and underestimate total occupancy cost. The institutional discipline is to model TI as what it is: a form of landlord financing embedded in the lease economics.
