Tenant Improvement Buildout Costs for Commercial Retail Space in the USA (2026): By Space Type, Region, and What Actually Drives the Number
Tenant Improvement Buildout Costs for Commercial Retail in the USA
What changed in tenant improvement pricing this month
TI economics shifted in May 2026 in three directions at once: landlord allowances tightened on second-generation retail, restaurant scope premiums grew, and second-gen MEP rework became the cost wildcard underwriters miss most often.
Landlord TI allowances in core retail markets tightened by 8 to 15 percent versus Q1 2026, per the latest CBRE U.S. Retail MarketView. The compression is driven by rising debt service on existing assets, a thinner pool of credit-quality tenants, and softer rent growth in commodity retail centers. Tenants in 2026 are paying more out of pocket, which means the gap between gross construction cost and the allowance is the new battleground in lease negotiations.
Restaurant TI moved up faster than any other use type. Type I hoods, grease interceptors, makeup-air units, and tighter NFPA 96 compliance on commercial cooking ventilation pushed kitchen scope by 6 to 9 percent versus the April benchmarks. Quick-service buildouts in QSR coffee formats and drive-thru concepts are pacing $260 to $480 per GSF, with full-service casual dining tracking $200 to $360 per GSF.
The wildcard nobody underwrites correctly is second-generation MEP rework. Existing electrical service that worked fine for the prior tenant is undersized for new use 40 to 60 percent of the time, especially when the new tenant adds EV charging, kitchen equipment, or medical imaging. Commercial electrical cost per square foot on TI work has risen faster than any other trade in 2026. Build a service-upsize line item into every TI estimate before pricing.
One cost driver moved down. Roll-up doors, store glass, and store-front aluminum systems normalized after the 2025 lead-time bubble, with 4 to 6 week lead times back in line. Material lead times across commercial construction stabilized broadly, which is the first time in 18 months tenants can sequence FF&E without a 90-day buffer.
Tenant improvement cost per square foot by use type (May 2026)
Per-gross-square-foot ranges from TCG preconstruction data, cross-checked against RSMeans 2026, JLL Retail Outlook, and the ICSC research library. Hard costs only on a second-generation space with average shell condition. Add soft costs and contingency separately.
Apparel discount, services, hair
Light interior demolition, paint, flooring, basic lighting, signage, minimal MEP. The cheapest TI tier when the shell delivers white-box or better.
Apparel, beauty, specialty
Branded fixtures, custom lighting, ceiling treatments, premium flooring, dedicated stockroom. Brand standards drive cost more than the base scope.
Luxury, jewelry, flagship
Stone, custom millwork, integrated lighting, smart glass, security, climate control. Brand experience is the line item that drives the per-foot.
Coffee, fast casual, drive-thru
Type I hood, grease interceptor, MUA, kitchen equipment, walk-in cooler, drive-thru tech, brand finishes. Health department adds permit time.
Casual, fine dining, bar
Larger dining envelope offsets per-foot kitchen cost. Bar plumbing, custom millwork, audio, lighting, acoustic treatment all add scope.
Primary care, dental, optometry
Lead-lined imaging rooms, medical gas, sound-rated walls, dedicated electrical, sterilization plumbing. Medical office build cost trends similarly.
Gym, yoga, recovery
Reinforced floors for free weights, MUA for class spaces, locker rooms, showers, dedicated electrical for cardio. Boutique concepts cost 30 to 50 percent more.
Tenant office, hot desk, hybrid
Open-plan low end, executive and coworking high end. Acoustics, AV, lighting controls, kitchenette and conference rooms drive premium ranges.
What the landlord delivers determines what the tenant pays
The single line item that swings TI cost more than any other is shell delivery condition. The same use type can be 30 to 50 percent more expensive in cold dark shell than in vanilla shell. Get the work letter in writing before you price the buildout.
Cold Dark Shell
Bare structure, exposed deck, slab on grade, exterior envelope only. No MEP rough-in, no demising walls, no utilities to space, no restroom. Tenant brings everything.
Gray Shell
Slab, exterior envelope, demising walls framed, MEP stubbed to space, no finishes, no ceiling, no flooring. The most common shell on new ground-up retail centers.
White Box
Finished demising walls primed and ready for paint, ceiling grid in place, basic lighting, MEP rough-in to space, slab sealed. ADA-compliant restroom typically included.
Vanilla Shell
Painted walls, finished acoustical ceiling, HVAC distribution, basic LED lighting, vinyl or polished concrete floor, working restroom. Tenant adds branded finishes and FF&E.
Second-Generation
Existing prior-tenant condition. Cost depends on demolition needed and how much existing MEP, fixtures, and finishes can be reused. Highest variance of any shell type.
The TCG decision rule on shell delivery
If the landlord is offering vanilla shell with a $40 per square foot allowance and a 7-year term, that lease pencils for most retail concepts. If the landlord offers a cold dark shell with the same allowance, the tenant is signing up for $50 to $90 per square foot of out-of-pocket cost the lease economics may not support. The work letter is where the deal is made or lost - never sign the LOI until shell condition and allowance are spelled out line by line.
Mid-tier retail TI cost by region
National averages obscure a 50+ percent regional spread. The bars below show TCG May 2026 benchmarks for mid-tier retail tenant improvement (apparel, specialty, beauty) across nine major regions, as a percentage of the national high end.
The spread reflects labor cost, prevailing wage, code stringency (especially seismic in California and energy code in NY and MA), permit timelines, and impact fees. State-level permitting timeline data tracks the regional cost premium closely. New York City and San Francisco TI projects routinely add 25 to 45 percent over national averages on labor and permit complexity alone.
From gross construction cost to net effective TI
The allowance is half the equation. The other half is what the tenant brings to the table - cash, lease amortization, vendor financing, or SBA. Get the allowance number and the net effective cost in writing before signing.
Landlord TI allowances in May 2026 generally land in five bands. CBRE retail data and Cushman & Wakefield MarketBeats show: vanilla-shell second-generation retail in a Class B center is typically $15 to $35 per SF; first-gen ground-up retail $30 to $60 per SF; medical office $40 to $120 per SF on long terms; restaurant $40 to $100 per SF when the landlord wants the food anchor; office $30 to $90 per SF with longer terms unlocking higher allowances.
Net effective TI cost is gross construction cost minus allowance, plus the present value of any rent abatement, divided by lease term. A 5,000 SF retail TI at $130 per SF gross cost ($650,000) with a $40 per SF allowance ($200,000) and three months of rent abatement on a $32 per SF lease (NPV roughly $40,000) yields net effective tenant cost of $410,000. On a 7-year term, that amortizes to roughly $58,500 per year, or $11.70 per SF per year of additional occupancy cost. That number must clear a four-wall margin test before signing.
Capital stack options for the tenant gap: cash, SBA 7(a) for owner-operator concepts, equipment financing for FF&E, vendor financing on coolers and POS, and SBA 504 for owner-occupied buildouts. Soft costs typically run 8 to 15 percent of hard cost on TI - lower than ground-up because design is faster and most of the structural and envelope decisions are already made.
The lease-economics test
For a deal to clear underwriting in May 2026, total occupancy cost (rent + CAM + amortized TI net of allowance) should land at 8 to 12 percent of projected sales for retail, 6 to 10 percent for full-service restaurant, 5 to 8 percent for QSR, and 12 to 18 percent for medical office. If TI cost pushes occupancy above the band, either negotiate higher allowance, longer term to amortize, or walk.

The TI line items underwriters miss
Five categories of cost destroy more TI budgets than any other. None of them show up in a back-of-envelope per-square-foot estimate. Build them into pricing before you sign.
1. Code-triggered ADA upgrades. A change in occupancy or scope above 20 percent triggers ADA path-of-travel upgrades to existing restrooms, entrances, parking, and accessible routes per the DOJ ADA Title III standards. Costs run $15 to $60 per SF of impacted space depending on existing condition. The landlord is rarely contractually obligated to fix these.
2. IECC and ASHRAE 90.1 envelope upgrades. A change of occupancy in jurisdictions that have adopted the 2024 IECC or ASHRAE 90.1-2022 can trigger envelope insulation upgrades, fenestration replacement, or HVAC commissioning. Costs run $8 to $25 per SF when triggered. Get a code-review letter from the AHJ before pricing.
3. Electrical service upsize. Existing 200A or 400A panels rarely support a restaurant, fitness, or medical buildout. Service upsize to 600A or 800A from utility meter through the panel can run $35,000 to $180,000 depending on transformer capacity and conduit run. 2026 electrical cost data shows this is the fastest-rising trade on TI work.
4. NFPA 13 sprinkler modifications. Demising-wall changes, ceiling height changes, and high-pile storage trigger sprinkler reconfiguration or full hydraulic recalculation. Costs run $4 to $12 per SF of impacted area. Expect 4 to 8 weeks of additional permit time when fire department review is required.
5. Grease, fat, and waste interceptors for any food use. Restaurant and any food-prep retail (poke, smoothies, ice cream, prepared foods) requires a code-compliant grease interceptor and often a fat trap, sized per local plumbing code. Installation runs $15,000 to $80,000 depending on whether the slab needs to be cut. Plumbing permits for food use add 4 to 10 weeks to the schedule.
The five mistakes that blow tenant improvement budgets
1. Pricing TI before getting the work letter in writing. The shell delivery condition is the single biggest cost variable. A "white box" promise without a written specification can mean anything from finished walls and ceiling to bare slab with painted CMU. Get the work letter line by line before you price construction.
2. Skipping the GC during lease negotiation. Nine of ten TI projects are designed over budget because the GC is not involved until after the lease is signed and design is locked. Bring the GC into preconstruction at LOI stage so the work letter and TI allowance can be negotiated against real numbers, not a back-of-envelope $/SF guess.
3. Underestimating second-generation MEP rework. "We can reuse the prior tenant's HVAC and electrical" is the most expensive sentence in tenant improvement. Existing systems are rarely sized for new use, the equipment is often near end-of-life, and the prior tenant's modifications were rarely permitted. Budget a service-upsize line item and an HVAC condition-assessment line item on every TI.
4. Choosing the lowest-bid GC on a fast-track schedule. The cheapest GC is rarely the fastest, and on TI work the rent-commencement date drives the financial outcome. A 30-day delay on a $40,000-per-month rent space costs more than the entire bid spread on most projects. Read the bid carefully for schedule, exclusions, and assumptions before awarding.
5. Locking finishes before pricing. Brand standards drive 30 to 60 percent of TI cost on premium retail and restaurant projects. If brand finishes were specified before construction pricing, the budget is set against a moving target. Lock pricing first against a generic spec, then layer brand finishes as priced alternates the tenant can accept or value-engineer.
Tenant improvement cost FAQ
In May 2026, basic retail TI costs $40 to $90 per gross square foot, mid-tier retail and apparel $90 to $180 per GSF, premium retail $150 to $300 per GSF, restaurant TI $200 to $500 per GSF, medical office $150 to $350 per GSF, and fitness $80 to $160 per GSF. Costs swing heavily with shell delivery condition. Add 8 to 15 percent for soft costs and 5 to 10 percent contingency.
Cold dark shell is bare structure with no MEP, demising walls, ceiling, or flooring. Gray shell adds rough-in MEP and slab. White box adds finished demising walls, basic lighting, ceiling grid, primed walls, and HVAC ready for tie-in. Vanilla shell adds painted walls, finished ceiling, HVAC distribution, and a working restroom. The cheaper the shell, the more TI cost falls on the tenant.
Landlord TI allowances in May 2026 range $15 to $35 per SF for second-generation retail in Class B centers, $30 to $60 per SF for first-generation ground-up retail, $40 to $120 per SF for medical office on long terms, $40 to $100 per SF for restaurant when landlord wants the food anchor, and $30 to $90 per SF for office. Higher allowances follow longer terms and stronger credit.
Restaurant TI costs roughly 2 to 3 times more per square foot than basic retail. Restaurants need a Type I hood, grease interceptor, makeup-air unit, full kitchen plumbing, NFPA 96 compliance, larger electrical service, and tighter ventilation. Quick-service and full-service ranges run $200 to $500 per GSF compared to $40 to $90 per GSF for basic retail.
Retail TI runs 8 to 16 weeks from permit to certificate of occupancy. Restaurant TI runs 12 to 22 weeks due to MEP scope, hood and grease interceptor inspections, and health department approval. Permitting often adds 4 to 12 weeks upstream depending on jurisdiction. Design-build delivery compresses both phases by 15 to 25 percent.
Five categories: code-triggered ADA upgrades ($15 to $60 per SF), IECC and ASHRAE 90.1 envelope upgrades ($8 to $25 per SF when triggered), electrical service upsize ($35,000 to $180,000), NFPA 13 sprinkler modifications ($4 to $12 per impacted SF), and grease and fat interceptors for any food use ($15,000 to $80,000). Add 5 to 10 percent contingency on second-generation spaces.
Both. Landlord typically funds a TI allowance against the lease; tenant funds the gap between allowance and total construction cost. Some landlords build to suit and amortize the cost into rent. Some tenants execute under a turnkey lease where landlord delivers a fully built space. The work letter in the lease defines who pays for what, line by line. Get this in writing before signing the LOI.
Hold the customer-touching surfaces (flooring, lighting, fixtures, signage, front-of-house finishes) and value-engineer the back-of-house, ceilings, MEP routing, and material substitutions where the customer never sees them. Bring the GC into preconstruction at schematic design, lock long-lead items first, and use GC procurement relationships on doors, lighting, and FF&E to capture 6 to 12 percent typical savings.
