Tenant Improvement Contractor (TI Contractor): What You Need to Know

The Hiring Decision That Sets Everything Else

The space is leased. The landlord is waiting. Your opening date is on the calendar. All that’s left is picking a contractor.

This is where a lot of TI projects start to go sideways.

Tenant improvement construction is not a commodity. Two contractors can bid the same scope and produce wildly different results in terms of schedule, cost control, finish quality, and whether your build-out actually complies with code by the time you’re supposed to open. The bid number is the least informative thing about them.

This guide is about everything that matters more than the number.

What Is a Tenant Improvement Contractor?

A tenant improvement (TI) contractor specializes in constructing or renovating commercial interior spaces for new tenants or for tenants upgrading an existing location. The work typically covers everything from demolition and framing to mechanical, electrical, plumbing, finishes, and fixtures.

TI projects happen in a specific context that makes them different from ground-up construction:

• You’re working within an existing building with existing systems, existing structural constraints, and an existing landlord relationship
• Your TI allowance from the landlord is often a fixed number, so managing scope to that budget matters as much as the construction itself
• Your lease commencement date is typically tied to a delivery deadline, meaning schedule overruns have real financial consequences
• The space usually needs to meet specific code requirements for your use type, which can vary significantly between, say, a medical office and a quick-service restaurant

A TI contractor who understands this context will manage it proactively. One who doesn’t will discover it during construction.

The 8 Questions to Ask Before You Hire

1. Have you built this specific type of space before?

Restaurant build-outs have different requirements than medical offices. Fitness studios have different MEP demands than retail. A contractor who has done 50 retail build-outs may struggle with a full-service restaurant kitchen ventilation system and not tell you that upfront.

Ask for a project list of comparable spaces. Not just commercial construction generally. Specifically the same use type you’re building.

2. Who will actually be running my project?

The person who sells you the project and the person who manages it day-to-day are often two different people. Ask to meet the project manager and superintendent who will be assigned to your job. Their experience matters more than the firm’s brochure.

Ask how many projects that PM is currently managing and whether they’ll be on your site regularly or available primarily by phone.

3. How do you handle scope that’s unknown at bid time?

Existing buildings have surprises. Hidden plumbing, old electrical that doesn’t meet current code, asbestos in 1970s drywall. Every experienced TI contractor has encountered them. What separates good ones from bad ones is how they handle it.

Ask how they communicate scope discoveries to you. Ask how they price change orders. Ask for a recent example of an unexpected condition and how they resolved it with the client.

4. What’s your relationship with your subs?

Most of the work on your project will be done by subcontractors. The GC’s ability to attract qualified, reliable subs matters for your schedule and your quality. A contractor who pays their subs late or treats them poorly will tell you nothing about this, but their subs will reflect it.

Ask how long they’ve worked with their primary mechanical, electrical, and plumbing subs. Repeat relationships signal a contractor people want to work with.

5. Can you provide a detailed cost breakdown before we’re under contract?

Rough estimates are easy. Detailed cost breakdowns require real work and commit the contractor to a number they have to defend. If a contractor won’t provide a line-item estimate until they have a signed contract, they’re protecting themselves at your expense.

Transparent pricing early in the process is one of the best indicators of how a contractor will behave when surprises come up during construction.

6. How do you coordinate with the landlord and their building standards?

Most commercial landlords have design guidelines and approval processes that your build-out has to clear before construction starts. An experienced TI contractor has navigated these before and knows what landlords typically approve, what they push back on, and how to move through the review process without losing weeks.

A contractor who dismisses this question or suggests you handle that coordination yourself has probably caused delays for other clients because of it.

7. What permits will this project require, and who handles them?

Permit requirements vary by municipality, building type, and scope of work. Some TI projects require building permits, fire department permits, health department approvals, and specialty inspections. Some contractors handle all of this. Others hand it off to you or to a third party.

Make sure you understand exactly who is responsible for permitting and inspections, what the realistic permit timeline is for your jurisdiction, and how permit delays are built into the schedule.

8. How do you handle punch list and closeout?

The end of a project is where many contractors fade. The big work is done, they’ve moved on to the next job, and your punch list items sit for weeks.

Ask what their typical punch list process looks like. Ask how long after substantial completion they expect full closeout to take. Ask for references specifically about how they handled closeout, not just how construction went.

Red Flags to Watch For

The TI Contractor Vetting Checklist

Use this before signing a contract with any tenant improvement contractor:

1. Confirm they have completed at least 3 to 5 projects of your specific use type
2. Verify the project manager assigned to your job, not just the company
3. Check references from recent clients, specifically about communication and closeout
4. Review their subcontractor relationships for key trades
5. Request a line-item cost estimate before signing
6. Confirm they handle permitting in-house or have a clear plan for it
7. Review change order terms in the contract carefully
8. Understand their landlord coordination process
9. Ask about current workload and confirm they have capacity for your project
10. Get their punch list and closeout process in writing

What Multi-Site Operators Should Prioritize

If you’re building more than one location at a time, or plan to build more in the future, the stakes on this hire are higher. A contractor who can build one good location but can’t scale the process costs you compounding time and money as your program grows.

For multi-site programs, look specifically for:

• Geographic coverage that matches your expansion footprint, not just your first location
• A repeatable delivery process with consistent project management structure across locations
• Centralized procurement that gives them leverage on materials pricing
• Experience with brand standards replication across different landlord building types
• Reporting and communication infrastructure that works at scale, including progress reporting and budget tracking across multiple active sites simultaneously

The contractor who builds your pilot location should be capable of building your 20th. Vetting them only against the first job is a mistake multi-site operators learn not to make twice.

Key Takeaways

• Tenant improvement contractors are not interchangeable. Experience in your specific use type matters more than general commercial construction volume.
• The project manager assigned to your job is often more important than the firm’s overall reputation. Meet them before you sign.
• Budget transparency before contract signing is a strong predictor of how a contractor will behave when scope surprises come up.
• Red flags like unusually low bids, vague PM staffing answers, or pressure to sign quickly are worth taking seriously.
• Multi-site operators should prioritize contractors with proven repeatable processes, not just contractors who can build one good location.

Frequently Asked Questions About Hiring a Tenant Improvement Contractor

1. What does a tenant improvement contractor do?

A TI contractor plans and builds out a commercial space to suit a specific tenant’s operational needs. That typically includes demolition of existing conditions, framing new walls, installing mechanical, electrical, and plumbing systems, and completing all interior finishes. Some also handle design, permitting, and landlord coordination.

2. How do I find a tenant improvement contractor?

Referrals from other commercial tenants, brokers, or your landlord are a reliable starting point. Industry associations like the Associated General Contractors of America maintain contractor directories. For national programs, working with a firm that has built in your target markets reduces the risk of hiring local contractors whose track record is unknown.

3. What is a TI allowance and how does it affect hiring?

A TI allowance is money provided by the landlord to offset the cost of your build-out. It’s typically negotiated as part of your lease and expressed as a dollar amount per square foot. A good TI contractor will help you scope your project against that allowance before construction starts, so you know exactly what the allowance covers and what you’ll be paying out of pocket.

4. What questions should I ask a TI contractor’s references?

Ask about communication throughout the project, not just whether it was finished. Ask specifically about how the contractor handled unexpected conditions, how change orders were managed, what the closeout process was like, and whether they would hire them again. References who only say ‘it was fine’ without specifics are less informative than you’d hope.

5. How long does a typical tenant improvement project take?

It depends heavily on scope, building complexity, and permit timelines. A simple retail build-out in a vanilla shell might take 6 to 10 weeks. A full-service restaurant with a commercial kitchen can run 16 to 24 weeks or more depending on equipment lead times and inspections. Your contractor should give you a schedule with milestones early in the process, not just an end date.

6. Who is responsible for permits in a TI project?

This varies by contract and contractor, so confirm it explicitly before signing. Many TI contractors handle permitting as part of their scope. Others pass it to the tenant or a third-party expediter. If you’re managing it yourself, make sure you understand the permit timeline for your municipality, because permit delays are one of the most common causes of missed opening dates.

7. Can I use my own architect and hire a separate contractor?

Yes. This is the traditional design-bid-build model. You hire an architect to complete drawings, then take those drawings to bid. The trade-off is that design and construction are managed separately, which can create coordination gaps and slower decision-making when issues come up. Design-build firms that integrate both under one contract are often faster and less prone to those gaps.

8. What is a vanilla shell in TI construction?

A vanilla shell is a commercial space that has been prepared by the landlord with basic infrastructure in place, typically framed walls, a concrete slab floor, rough electrical and plumbing stubs, and basic HVAC. It’s ready for tenant-specific build-out but not finished. The TI contractor takes over from there. Gray shell spaces require more work because even the basic systems may not yet be in place.

9. How do I know if a bid is too low?

Compare line-item detail across bids, not just the total. A low bid that doesn’t break out key trades, doesn’t include allowances for unknown conditions, or excludes items that other bidders included is not actually lower. It’s incomplete. Ask every bidder to use the same scope document and request clarifications on anything one contractor excluded that others included.

10. What happens if the project goes over budget?

That depends on your contract. Time and materials contracts pass cost risk to you. Fixed-price contracts cap your exposure. A GMP (Guaranteed Maximum Price) structure protects you from going over a set number, with the contractor absorbing any overrun. For TI projects with a fixed allowance, a fixed-price or GMP contract structure is worth negotiating for, because the budget ceiling is real.
