When you lease a commercial space, one of the first questions that comes up is:

What is the tenant improvement cost per SF?

Whether you’re planning an office build-out, retail renovation, medical suite, or industrial upgrade, understanding tenant improvement (TI) costs per square foot helps you budget wisely, negotiate your lease effectively, and avoid surprises.

At APX Construction Group, we guide clients across Minnesota and South Dakota through strategic tenant improvements that align budget, timeline, and long-term operational performance.

What Is Tenant Improvement (TI)?

Tenant improvement refers to the customization or renovation of a leased commercial space to meet a specific tenant’s needs. This can range from minor cosmetic upgrades to full structural reconfiguration.

Common TI projects include:

• Office build-outs
• Retail store build-outs
• Restaurant interior construction
• Medical or dental suite renovations
• Warehouse office additions
• Tenant demising walls
• Mechanical and electrical upgrades

If you’re leasing shell or second-generation space, TI costs will vary significantly depending on the scope.

Average Tenant Improvement Cost Per SF in 2026

Tenant improvement costs typically range between:

Space Type	Estimated Cost Per SF
Basic Office Refresh	$25–$50 per SF
Mid-Range Office Build-Out	$50–$100 per SF
High-End Office / Corporate	$100–$200+ per SF
Retail Build-Out	$75–$150 per SF
Medical Office	$150–$300+ per SF
Restaurant	$200–$400+ per SF
Industrial Office Add-On	$40–$90 per SF

Important: These are national averages. Local labor markets, material pricing, and code requirements in Minnesota and South Dakota will impact final numbers.

What Impacts Tenant Improvement Cost Per Square Foot?

Understanding cost drivers helps you control them.

1. Condition of the Existing Space

• White box shell = higher build-out cost
• Second-generation office = lower cost
• Major mechanical upgrades = higher cost

2. Mechanical, Electrical & Plumbing (MEP)

HVAC systems, upgraded lighting, plumbing for restrooms, and specialty power for equipment can significantly increase the cost per SF.

3. Layout Changes

Moving walls, adding offices, creating conference rooms, or reworking circulation increases labor and material costs.

4. Finish Selections

• Standard carpet + paint = lower cost
• Custom millwork + glass partitions = higher cost
• Specialty flooring, acoustic treatments, or architectural ceilings = premium range

5. Code Compliance & Permits

Fire suppression updates, ADA upgrades, and energy code compliance add scope but protect long-term performance and safety.

Tenant Improvement Allowance (TIA): What You Need to Know

Landlords often offer a Tenant Improvement Allowance (TIA) expressed as a dollar-per-square-foot allowance.

Example:
If your landlord offers $40 per SF and your project costs $85 per SF, you are responsible for the $45 per SF difference.

Negotiating a strong TI allowance can dramatically impact upfront capital investment. A knowledgeable commercial general contractor like APX can assist during lease negotiations by providing realistic budgeting guidance.

Office Tenant Improvement Cost Breakdown

Here’s a simplified cost distribution for a mid-range office TI project:

• Framing & Drywall: 15–20%
• HVAC & Electrical: 20–30%
• Flooring & Finishes: 15–25%
• Millwork & Casework: 10–20%
• Permits & Design Fees: 5–10%
• General Conditions & Project Management: 10–15%

Every project is unique — but transparency in budgeting ensures alignment from the beginning.

How to Reduce Tenant Improvement Cost Per SF

Smart preconstruction planning makes a measurable difference.

✔️ Invest in Preconstruction

Early budgeting, design coordination, and value engineering reduce change orders and prevent overruns.

✔️ Keep Structural Changes Minimal

Working within the existing footprint reduces demolition and rebuild costs.

✔️ Standardize Finishes

High-impact design doesn’t require premium materials everywhere. Strategic focal points can maintain brand presence without driving cost per SF too high.

✔️ Plan Long-Term

Choosing durable finishes reduces lifecycle cost — even if upfront TI cost per SF is slightly higher.

TI Costs by Industry

Office Spaces

Modern offices focus on collaboration zones, sound control, and integrated technology. Cost per SF depends heavily on glass partitions, AV systems, and millwork.

Retail

Retail tenant improvements require strong lighting, storefront customization, and brand-focused finishes. Flooring and specialty displays often increase per-SF cost.

Medical & Healthcare

Medical spaces have strict code requirements, specialized plumbing, and enhanced HVAC systems. These typically fall into the higher-cost tiers.

Industrial & Warehouse

Industrial TIs are typically lower per SF unless office build-outs or specialty systems are included.

Timeline Considerations for Tenant Improvements

Tenant improvement projects typically follow this timeline:

1. Programming & Budgeting: 2–4 weeks
2. Design & Engineering: 4–8 weeks
3. Permitting: 2–6 weeks
4. Construction: 6–16 weeks

Scope complexity drives duration. Early coordination prevents delays.

Real-World Example

Let’s say you’re leasing 5,000 SF of office space:

• TI Cost: $85 per SF
• Total Project: $425,000
• Landlord TIA: $40 per SF ($200,000)
• Tenant Investment: $225,000

Without early contractor involvement, costs could climb quickly. Strategic planning protects your bottom line.
