Tenant Improvement Allowance: What It Covers and How to Negotiate It

Tenant improvement (TI) allowances in gateway office markets are stagnating or even pulling back after peaking in 2025, capping a run lasting more than 10 years.

With sluggish rent growth and landlords regaining some leverage after several years of pandemic softness, allowances are no longer being conceded as reliably in negotiations. At the same time, construction costs keep rising every quarter. But what does this actually mean for tenants and how can you still negotiate higher TI allowances in the current context?

This guide covers what an allowance actually funds, where the figures currently sit and which parts of the package still have headroom.

What Is a Tenant Improvement Allowance?

A tenant improvement allowance is the landlord’s contribution toward customizing your space, quoted per rentable square foot or as a lump-sum cap, and limited to permanent improvements that stay with the building after you leave.

The detail that catches first-time tenants out is that cash allowances are a reimbursement, not a payment. You hire the contractor, you settle the invoices, and the landlord repays you once the work is documented and inspected. On a mid-size build-out, that can mean carrying six figures for several months.

Landlords don’t size the allowance around your design. Instead, the final allowance figure tracks vacancy and building quality far more closely than your floor plan. A standard TI allowance is usually situated between 25% to 150% of one year’s base rent, with anything past 100% being a genuine landlord concession.

One more definitional check worth making early is confirming which square footage the calculation runs on. Rentable and usable areas can differ by 15% to 20% on a multi-tenant floor, so ensure you start your improvement plan with the real calculation.

How Much Is a Typical TI Allowance Per Square Foot in 2026?

TI allowances have largely stagnated in 2026, continuing the trend started in the second half of 2025. Newmark puts allowances in major markets about 75% above their 2015-2019 average — up from 61% a year earlier, but climbing at a visibly slower pace each quarter, meaning you can’t be certain of a more sizable allowance if you hold off for a few more quarters.

More granularly, TI allowances for Manhattan office leases averaged $140 per square foot in the first half of 2026 according to Colliers, on par with the level the market has held since 2023. In Midtown Manhattan‘s trophy tier, a pullback concessions is already visible with average TI falling from $162 to $133 per square foot over the past year.

As inventories in prime markets continue to pivot towards Class A and A+ space, building owners are starting to trim concessions. Among Class B properties in less ideal locations, TI offers remain competitive, but many landlords may have hit the ceiling of what their income can support in terms of tenant improvement concessions, instead turning towards free rent.

For tenants, the result is simple. TI allowances are lagging behind construction costs, resulting in lower customizability compared to previous years. The most negotiable allowances are currently in solid, well-located properties that still carry above-average vacancy rates.

What Do Tenant Improvement Allowances Typically Cover?

Allowances fund hard construction: demising walls, doors, flooring, ceiling grids, standard lighting, HVAC distribution, basic plumbing and paint. Code-driven work such as ADA-compliant restroom modifications also usually qualifies.

Furniture, fixtures and equipment, data cabling, audiovisual systems, signage and business-specific installations are typically excluded, as are soft costs like architecture, engineering, permits and project management, unless the work letter names them.

The gap between the allowance and the actual bill is now the central math of any lease deal. Cushman & Wakefield puts U.S. fit-out hard costs around $200 per square foot in gateway markets, up about 5% year over year. New York City runs at $213 in hard costs alone, and roughly $331 all-in once furniture, IT, audiovisual and soft costs are layered on top.

Applying these costs to a 5,000-square-foot Manhattan suite results in roughly $700,000 of allowance against $1.06 million in hard construction, before a dollar of furniture or cabling, with the gap likely widening in future quarters.

Smaller tenants feel this math most sharply, because a build-out’s fixed costs don’t scale down neatly. The insider’s guide to NYC commercial office leases for early-stage teams walks through how it lands on a first lease.

What’s Actually Negotiable in a TI Allowance?

Often, the headline figure is the least flexible part of the package. Landlords model TI against a return threshold, and past a certain point they would rather concede free rent than more construction money. The terms wrapped around the allowance usually have more give, and they can be worth more.

Start with delivery structure. A cash allowance keeps you in control of contractor selection and finish quality. A turnkey build hands the landlord both scope and risk, which suits teams without construction capacity but costs control over the outcome. An amortized allowance is a loan dressed as a concession — more on that below.

Lease term remains the most reliable lever on the number itself, since a seven-year commitment gives the landlord that much longer to recover the spend. Beyond term, these points usually stay on the table:

• Eligible cost categories. Architecture, engineering, permitting and project management can all be written into the work letter, typically running around 10% of a build-out budget.
• Disbursement schedule. Progress draws tied to milestones beat one reimbursement at completion. Expect each draw to require invoices, lien waivers, insurance certificates and AIA G702/G703 forms, plus a certificate of occupancy for the final payment.
• Retainage and timing. Landlords commonly hold back 10% until completion, with payment landing 30 to 60 days after a clean draw package.
• Construction management fees of 3% to 5% of construction cost, charged for supervising work you’re already paying for. Ask for a cap or a waiver.
• The use-by deadline, often six to 12 months from lease commencement.
• Rollover of unused funds into a rent credit. Some leases allow it if specifically included in the agreement, so don’t take it as a given.

There’s also a new tax lever worth raising. The full expensing of qualifying interior improvements restored in July 2025 lets tenants deduct build-out costs immediately rather than depreciating them over decades. It changes what an allowance-versus-rent trade is worth, so put the work letter in front of your accountant before the LOI is signed. The same discipline applies when negotiating a serviced office deal: the structural terms move total cost more than the headline rate does.

Red Flags to Watch for Before You Sign

The clause most likely to produce surprises is restoration, sometimes called make-good. It requires you to return the space to its original condition at lease end, which on a customized fit-out means paying to demolish work you already paid to build. The fix is to ask to narrow the obligation to non-standard alterations and require the landlord to state at the point it approves each alteration whether removal will be required at expiry.

Amortized allowances are the also a common trap for tenants. The landlord funds a larger number upfront, then recovers it through rent at 7% to 10% interest. Financing an extra $20 per square foot over five years at 8% adds roughly $4.87 per square foot a year, equal to almost $49,000 annually on a 10,000-square-foot suite, none of it visible in the base rent line.

Two less common red flags deserve a look. A large allowance can trigger a bigger security deposit or a letter of credit, tying up cash exactly when construction is consuming it. Additionally, you should confirm the work letter survives a sale rather than assuming it does in case the building trades mid-lease.

When the Build-Out Math Stops Making Sense

A conventional fit-out runs four to 10 months from signed lease to occupied desk once design, permitting and construction are counted. Landlords have responded by building pre-built spec suites which now lease around four and a half months faster than comparable shell space, which is why turnkey office space in NYC has become a standard tool in buildings chasing tenants under 15,000 square feet.

The flexible market takes that logic one step further. Hubble’s Q2 2026 New York office report puts the average private office in Manhattan at $821 per desk per month — up 4.6% on the quarter — against $720 in Brooklyn, across 15.2 million square feet of flex inventory citywide. Those figures cover rent, fit-out, furniture and services in one line, with no draw schedule, no amortization and no restoration clause waiting at lease end. The same report has Manhattan office vacancy holding at 13.1%, about 450 basis points below the national benchmark, which explains why per-desk pricing is firming there faster than elsewhere.

None of this makes flex the default answer. At scale, over a seven- or 10-year term, a conventional lease with a strong allowance usually wins once the fit-out is amortized across the full period. But, looking at periods of under three years or with headcount you can’t forecast, the math may favor flexibility. The differences between serviced, managed and leased offices set out where each structure earns its keep so make sure you weigh each option before committing to one type.
