What is Tenant Improvement (TI) Work?

Tenant Improvement refers to the customized alterations a building owner or tenant makes to a commercial space to configure it for the tenant’s specific needs. This could be anything from building private offices in a shell space to updating lighting, HVAC systems, and IT infrastructure for a tech company moving into an older suite.

TI projects are common in retail, office, healthcare, industrial, and hospitality environments—anywhere a space needs to be tailored for a new occupant. These jobs are often high-speed, high-stakes, and budget-sensitive because tenants typically want to open for business fast—and every day of delay costs money.

What makes TI projects so difficult isn’t necessarily the complexity of the work—it’s the unpredictability of the process. And if you don’t account for those hidden variables upfront, they’ll hit your schedule, budget, and team hard.

Major Pain Points in Tenant Improvement Projects

‍

Budget Constraints (and How They Spiral)

Tenant improvement budgets are often set before any demolition begins, usually in the form of a tenant improvement allowance provided by the landlord. These allowances are often based on best-case-scenario estimates, not real-world conditions. Once you start peeling back drywall or lifting floor tiles, the budget can unravel fast.

Common budget-busting issues include:

• Upgrades to outdated or non-compliant MEP systems
• Structural retrofits to meet code
• Finish upgrades requested after the fact
• Extended overtime or weekend work due to building access rules

What’s worse, costs aren’t always clearly divided between landlord and tenant, which can stall decision-making and delay change orders.

Unforeseen Conditions in the Existing Space

No matter how thorough the walkthrough, you never truly know what’s behind the walls until demolition starts. Old buildings, in particular, often come with layers of surprises—some that could trigger costly remediation efforts.

Some of the most common hidden conditions include:

• Unlabeled or undocumented electrical circuits
• HVAC ductwork running through demo zones
• Outdated fire suppression systems
• Water damage or mold inside ceilings or behind walls
• Inadequate or missing insulation

Addressing these issues not only requires quick pivoting but also introduces scheduling conflicts among trades, especially when work has to pause while new scopes are assessed and approved.

‍

Limited Working Hours and Access Restrictions

TI projects in occupied buildings face one of the biggest logistical hurdles: access. Building management may limit when and where contractors can work, which compresses your productivity window and creates scheduling headaches.

Typical limitations include:

• Night and weekend-only work to avoid disrupting existing tenants
• Noisy work restricted to specific hours
• Delivery constraints due to dock or elevator access
• Security clearance requirements and escorted access

All of this means you may need to staff up for swing shifts, work off-hours, or double your efforts on weekends just to meet the original project schedule. Even basic deliveries become logistical puzzles.

‍

Permit Delays and Code Compliance

Permitting timelines are rarely predictable, especially when you’re retrofitting older structures. Local jurisdictions may have unique code requirements, and inspectors often request changes that were not scoped in the original plan. This can trigger rework or even full redesigns, particularly when plans run up against fire code, ADA compliance, or energy regulations.

Common permitting challenges include:

• Extended wait times for plan review
• Rejected inspections requiring rework
• Code updates that weren’t in effect at project start
• Additional requirements triggered by occupancy or building type

Staying ahead of code is essential—but not always possible in reactive environments like TI, where you don’t know what you’re dealing with until walls come down.

‍

Last-Minute Design Changes

Clients rarely have full visibility into how a space will look and feel until the framing is up and finishes start going in. That’s when the change requests start coming in—some small, others substantial.

Design change requests that affect multiple trades include:

• Moving walls or doorways
• Reconfiguring lighting layouts
• Changing flooring or ceiling materials
• Adding IT, AV, or security infrastructure
• Upgrading millwork or countertops

Every change means revisiting drawings, re-engaging vendors, and rescheduling trades—sometimes more than once. It also often leads to disputes over scope creep and cost sharing, which further bogs down progress.

‍

Why TI Projects Feel So Overwhelming

TI jobs are the definition of “high coordination, low control.” You’re working under strict budget and schedule pressures with a dozen or more moving parts:

• Tenants with evolving needs
• Landlords with building restrictions
• Inspectors enforcing new standards
• Subcontractors juggling multiple jobs
• Suppliers with unpredictable lead times

There’s little room for error, and even less time to react when things go sideways.

It’s a lot to manage—and you’re often doing it with limited staff, unclear communication channels, and tight margins. No wonder even seasoned GCs find TI work especially stressful.
