Tenant Improvement Allowances in 2026: What's a Fair TI Package and How to Negotiate It

Every operator who has ever leased a restaurant, salon, medical office, or retail storefront has had the same experience: you find a space you love, then you find out what it costs to turn a concrete shell into a functioning business. That's where the tenant improvement (TI) allowance comes in — and misunderstanding it is one of the most expensive mistakes a first-time commercial tenant can make.

What a TI Allowance Actually Is

A tenant improvement allowance is money a landlord contributes toward the cost of building out your leased space — almost always expressed as a dollar amount per square foot, paid either directly to your contractor against draw requests or reimbursed to you after construction is complete (LoopNet, "Tenant Improvement Allowance (TIA) in Commercial Real Estate"; The Cauble Group, "Tenant Improvement Allowance: 2026 Ranges + Calculator"). If a landlord offers $30 per square foot on a 3,000-square-foot space, that's a $90,000 budget toward your build-out (The Cauble Group).

The number is almost never enough to cover your entire project. It typically covers the "shell-to-suite" improvements that become part of the building — walls, flooring, ceilings, HVAC distribution, electrical and plumbing rough-in — and typically excludes furniture, signage, specialty equipment, and technology infrastructure (Custom Home Design and Build, "Bay Area Commercial Tenant Improvements 2026"). Whatever your buildout costs beyond the allowance comes out of your own capital, unless you negotiate it into rent (more on that below).

What's a Fair TI Package? Real Benchmarks by Property Type

TI allowances vary enormously by property type, building class, lease length, market, and how "finished" the space already is (a second-generation space that already has flooring and HVAC needs far less than a raw shell). The most authoritative national benchmark comes from CBRE's own lease-transaction analysis: across nearly 3,900 office leases in 12 major U.S. markets since 2019, the average tenant-improvement allowance was $94.69 per square foot in the first half of 2024, down nearly 3% from $97.55 in 2023 after four straight years of increases (CBRE press release, "Office Lease Concessions Like Free Rent and Tenant-Improvement Allowances Declined"). That same analysis found a meaningful split by building quality: top-tier (Class A+/A) office assets averaged a $98 per square foot allowance, while lower-tier (Class B/C) buildings averaged $86 per square foot — both up sharply (37% and 51%, respectively) since 2019 as landlords compete harder for tenants (CBRE, "Top-Tier Office Effective Rents Rise as Concessions Fall in H1 2024").

For small-business tenants outside major-metro Class A office towers, the ranges are generally lower and vary more by property type than by building class. Industry benchmarking from commercial brokerages and construction firms converges on a fairly consistent pattern:

Typical TI Allowance Ranges by Property Type ($/SF)

These are national directional ranges compiled from multiple brokerage and construction-industry sources; treat them as a starting point for negotiation, not a quote — confirm against local comps in your specific submarket.

It's worth noting the gap between the allowance and your actual construction cost. According to JLL's U.S. and Canada Office Fit-Out Cost Guide, the national average for a moderate-quality office fit-out was around $280 per square foot in early 2025 (Archgeneral Construction, citing JLL's 2025 Fit-Out Cost Guide) — meaning even a generous $75–$100/SF TI allowance leaves a large gap for many buildouts. Restaurant and medical spaces carry the widest gaps of all, since commercial kitchens, grease interceptors, and medical-grade plumbing and electrical infrastructure are expensive regardless of how much the landlord contributes.

How Landlords Actually Calculate a TI Offer

Landlords aren't picking a number at random. Two mental models drive most TI offers:

1. A percentage of your first year's rent. A commonly cited industry rule of thumb is that a reasonable TI allowance lands somewhere between 25% and 150% of one year's base rent — below that range and you may be leaving money on the table; above it, you're asking the landlord to underwrite a lot of risk on an unproven tenant (The Cauble Group). A related version of the same logic: expect roughly $5–$10 per square foot of allowance for every year of your lease term, so a 5-year lease might justify $25–$50/SF while a 10-year lease could support $50–$100/SF, because the landlord is amortizing their investment over your commitment (PropertyCEO).

2. Amortized into your effective rent. Institutionally, landlords think of TI as a reduction to their effective rent: they divide the total TI dollars by your lease term in years, and that annual number comes straight off their bottom line even though it shows up to you as cash for construction (Apers, office underwriting analysis). This is why landlords are often willing to raise the TI number if you extend your lease term — it's the same economic bet stretched over more years.

Market conditions also matter enormously. In a market with high vacancy, like much of the office sector right now, landlords compete harder for tenants and TI allowances rise; in a tight market, like most quality retail space today, landlords have less incentive to sweeten the deal with cash and would rather hold firm on rent (Bowser Construction Group, "Tenant Build Out Costs 2026").

What's Actually Negotiable

Tenants often treat the TI number on the landlord's first offer as fixed. It rarely is. Here's what's usually still on the table:

• The dollar amount itself. Especially in a market where the landlord has meaningful vacancy risk, this is your single biggest lever.
• Lease term in exchange for a bigger allowance. Landlords will frequently trade a longer commitment for more TI dollars up front, since they're amortizing the cost either way.
• Turnkey vs. allowance structure. You can sometimes ask the landlord to build out the space to your specifications directly (a "turnkey" deal) rather than handing you cash — this shifts construction-cost risk to the landlord, which can be valuable if you're worried about contractor bids running over.
• Timing and disbursement mechanics. Whether the allowance is paid directly to your contractor against draws, or reimbursed to you after the fact, has real cash-flow implications — a reimbursement structure means you need to front the money and wait to get paid back.
• What counts as "qualifying" work. Push to get soft costs (architectural and engineering fees, permit costs) included in the allowance, not just hard construction costs.
• Excess allowance treatment. Ask what happens to unused TI dollars — some leases allow you to apply savings toward rent abatement rather than losing them.

Common Mistakes Tenants Make

Treating the headline number as the real number. A $50/SF allowance sounds generous until you realize your restaurant buildout will run $200–$400+/SF once kitchen equipment, hoods, and grease traps are factored in (ConstructionBids.ai, "Restaurant and Retail Tenant Improvement Bids: Complete 2025 Guide"). Get real contractor bids before you negotiate, not after.

Not knowing the tax treatment. A TI allowance is generally taxable income to the tenant unless it qualifies for exclusion under IRC Section 110, which applies to certain retail leases of 15 years or less where the funds are spent on long-term real property that reverts to the landlord (GrowthFactor, "Tenant Improvement Allowance: Negotiate TI (2026)"). Confirm your specific lease language with a CPA — this can materially change your effective allowance.

Skipping the disbursement schedule. If your lease reimburses you rather than paying your contractor directly, you need to finance the full construction cost yourself and wait for reimbursement. That's a cash-flow problem many first-time operators don't plan for.

Negotiating TI in isolation from rent and term. TI, base rent, free rent, and lease length are all connected — a landlord who won't move on TI dollars might move on months of free rent instead, and vice versa. Negotiate the whole economic package, not one line item.

Not budgeting the gap before signing the LOI. Your letter of intent, not the final lease, is when you have the most leverage to lock in delivery condition and allowance amount (GrowthFactor, "Retail Build-Out Costs: What to Budget (2026)"). Waiting until after the LOI to figure out your real construction number is backwards.

A Step-by-Step TI Negotiation Checklist

1. Get a real cost estimate before you make an offer. Talk to a contractor or use a buildout planning tool to price your actual scope of work — kitchen equipment, plumbing, electrical, HVAC, finishes — for the specific space you're considering.
2. Research comps in your specific submarket and property type. National averages are a floor for the conversation, not the answer; ask your broker for actual recent TI comps in your trade area.
3. Decide your ask before the landlord makes their offer. Anchor the negotiation with your number, tied to your real construction estimate, rather than reacting to theirs.
4. Negotiate TI, term, and free rent together. Know which lever matters most to your cash flow and be willing to trade across all three.
5. Push to lock terms into the letter of intent, including delivery condition (shell vs. white box vs. turnkey) and the specific allowance amount — this is your highest-leverage moment.
6. Clarify the disbursement mechanism. Confirm whether funds go directly to your contractor or reimburse you, and negotiate a favorable schedule if it's the latter.
7. Get the "qualifying improvements" definition in writing. Make sure architectural/engineering fees and permit costs are included, not just hard construction costs.
8. Ask about unused-allowance treatment and confirm tax treatment with your CPA before you assume any of the allowance is free money.

Price Your Buildout Before You Ask for a Number

The single biggest advantage in a TI negotiation is walking in with your own accurate cost estimate instead of guessing. Before you counter a landlord's offer, it's worth running your concept through a buildout planning tool to get a preliminary floorplan, equipment list, and cost estimate — BuildoutIQ is one free option that can help you get real numbers fast, so your TI ask is grounded in your actual project rather than a rule of thumb.
