How to Choose the Right Contractor for a Commercial Tenant Improvement Project
A commercial tenant improvement (TI) project can reshape how a team works, collaborates, and shows up in their space. Yet even with the best design, the wrong contractor can set a project back before it ever gets off the ground.
In fact, in a review of building projects, one systematic study showed that issues like poor planning and coordination came up in about 70–74% of the documents analyzed.
Owners and brokers feel this pressure firsthand. A TI has to open on time, stay within budget, and meet the quality expectations of the tenant, the building, and the brand.
With so many moving parts, choosing the right contractor becomes less about flipping through proposals and more about understanding how a team plans, communicates, and solves problems long before demolition begins.
If you’re preparing for a tenant improvement project, the guidance below offers a clear, practical way to evaluate contractor fit. Let’s talk about what to ask, what to look for, and how to avoid the common pitfalls that slow commercial projects down and inflate costs.
(1) Start With Experience That Matches Your Scope
Not every commercial contractor builds TI projects every day. Some focus on ground-up construction, some on specialty trades, and some (like top tenant improvement builders in LA and Orange County) focus almost exclusively on interior renovations.
When reviewing experience:
Look for recent TI projects similar in size, type, and complexity.
Ask for case studies or a project list, not just a general résumé.
Clarify whether they have experience working in occupied spaces, multi-tenant buildings, or Class A offices, depending on your project.
A contractor familiar with your building type already understands the common constraints: freight elevator scheduling, noise windows, parking logistics, after-hours work, and coordination with building engineers.
(2) Ask About Their Approach to Preconstruction
Before a single wall comes down, a TI project is already won or lost in the planning phase.
Preconstruction is where contractors translate ideas and drawings into something buildable, predictable, and grounded in real-world constraints. It’s also where experienced teams catch issues that could otherwise turn into schedule delays, rushed substitutions, or expensive change orders later on.
A strong preconstruction process gives owners and brokers clarity early: what the project will cost, how long it will take, and what challenges need to be solved before the first crew steps on-site. Contractors who take this stage seriously bring stability to the entire project, because the decisions made here ripple through every trade and every week of the schedule.
Strong contractors will:
Provide detailed preconstruction feedback, not vague estimates.
Flag long-lead materials early so your schedule doesn’t get blindsided.
Work directly with architects and engineers to resolve design gaps before they become change orders.
Produce realistic schedules built on data from current subcontractor markets.
Questions to ask:
“What is your preconstruction process?”
“How do you handle design inconsistencies or incomplete drawings?”
“What long-lead items do you expect on a project like this?”
If a contractor can speak clearly and calmly about these topics, it’s a good sign they’ve lived through TI challenges and know how to prevent them.
(3) Evaluate Schedule, Budget, and Quality (and How They Balance Them)
Every tenant improvement project rests on a familiar triangle: schedule, budget, and quality. Most teams can deliver two without much trouble, but getting all three requires discipline, planning, and a contractor who’s honest about what’s achievable.
Owners and brokers often find that the real difference between contractors isn’t whether they can hit a date or meet a budget, but how they make decisions when those priorities start to pull against one another.
A trustworthy builder will be open about:
Which parts of your schedule are fixed and which have flexibility
What costs are predictable, versus where uncertainties may surface
How they maintain quality while meeting timing and budget constraints
A helpful question to ask: “Tell us about a time when you had to choose between schedule, cost, and quality, and how you responded.”
Their answer will reveal:
Whether they cut corners
How they communicate when issues arise
How they protect the client’s interests
In commercial interiors, quality often shows up in the details: alignment, finishes, mechanical balancing, clean transitions, and well-coordinated punch lists. A contractor who talks about these small things is usually one who pays attention to them.
(4) Confirm Licensing, Safety, and Insurance
Before comparing bids or schedules, it helps to make sure the basics are firmly in place. Licensing, safety practices, and insurance coverage may not feel as exciting as design details or finish selections, but they’re the backbone of a well-run TI project.
Check:
State contracting license
General liability and workers’ compensation coverage
EMR (Experience Modification Rate) as a snapshot of their safety history
Safety program documentation or certifications
If something does go wrong during construction, proper licensing, strong safety systems, and adequate insurance ensure everyone is protected and that the project can progress.
(5) Look Closely at Their Subcontractor Relationships
Tenant improvement projects move quickly, and much of that speed depends on the subcontractors who handle the day-to-day work. Even the strongest GC relies on their subs to keep the job moving, communicate clearly, and maintain craftsmanship across every trade.
That’s why a contractor’s relationships with their core subcontractors can tell you more about the project’s stability than any proposal or presentation.
Ask:
“How long have you worked with your core subcontractors?”
“How do you qualify new subs?”
“How do you handle subcontractor scheduling conflicts?”
Contractors with long-standing sub relationships typically deliver more predictable pricing, stronger accountability, and smoother coordination from start to finish. Newer or constantly rotating subs can mean re-learning expectations, inconsistent workmanship, and unnecessary delays.
When a contractor can point to a stable, well-vetted sub network, it’s a strong sign that your project will benefit from that same consistency.
(6) Consider Their Communication Style
A commercial contractor can be qualified on paper but difficult to work with day-to-day. Miscommunication is one of the most common reasons tenant improvement projects run into delays.
Ask for clarity on:
Weekly meeting structure
How they share updates, logs, and schedules
Who your main point of contact will be
How they handle unexpected issues or design changes
You’re looking for a team that communicates early, directly, and without drama. Your commercial contractor should keep everyone calm and focused even when something doesn’t go as planned.
(7) Review Past Performance and References
Instead of asking, “Were you happy with them?” try targeted questions such as:
“Did they meet the schedule they promised?”
“How did they handle change orders — proactively or reactively?”
“Were there surprises during closeout?”
“Would you hire them again for the same type of project?”
Experienced owners and brokers will give honest, specific answers when the project went well (or when it didn’t) and their firsthand perspective can help you gauge how a contractor performs under real pressure, not just in a polished proposal.
(8) Make Sure They Understand Building Management
In many office towers, the building engineer and property manager play an outsized role in a TI’s success. A contractor who already knows the building’s rules, approval timelines, loading dock limits, and after-hours policies can save weeks of coordination.
Ask:
“Have you worked in this building before?”
“What do you anticipate as the biggest building-related constraints?”
A good GC will answer this without hesitation, and their response will give you a clear sense of whether they can handle the building’s expectations, keep approvals moving, and prevent small logistical issues from slowing the entire project down.
