Tenant Improvement (TI) projects are all about adapting a space to meet the functional, operational, and branding needs of a new tenant. While finishes and layouts often get the spotlight, electrical planning is what truly determines whether a TI project runs smoothly or turns into a costly headache.

From compliance issues to capacity limitations, overlooking electrical considerations can delay occupancy, drive up costs, and strain tenant relationships. Here’s what truly makes or breaks electrical work in tenant improvement projects and how to get it right from the start.

Understanding Existing Electrical Capacity

One of the most common challenges in tenant improvement projects is discovering too late that the existing electrical infrastructure cannot support a tenant’s operational needs. Before design or construction begins, it’s critical to evaluate key factors such as service size and available amperage, existing panel capacity and breaker availability, the condition of switchgear and feeders, and accurate load calculations based on how the tenant will use the space. 

Retail, office, healthcare, data, and light industrial tenants all have dramatically different electrical demands, and identifying those needs early helps prevent mid-project redesigns, costly change orders, and unnecessary delays.

Matching Design to Actual Use

Electrical layouts must align with how the space will be used, not just how it looks on plans. This includes anticipating workstation density and power needs, specialized equipment requirements, and HVAC and mechanical loads. 

You should also consider lighting levels and controls, as well as the potential for future expansion. Failure to coordinate with tenants about operational needs often leads to excess rewiring, delayed inspections, or costly post-occupancy changes.

Code Compliance and Permitting

TI projects must comply with multiple codes and regulations, including:

• NEC (National Electrical Code)
• Local building and fire codes
• ADA requirements
• Energy efficiency standards

Electrical work that doesn’t meet code can stop a project in its tracks during electrical inspections. Worse, noncompliant installations can create safety hazards and liability risks long after the tenant has moved in. Conversely, an experienced electrical contractor ensures all designs, installations, and documentation meet jurisdictional requirements, avoiding rework and inspection failures.

Lighting Design and Energy Efficiency

Lighting plays a major role in both tenant satisfaction and long-term operating costs. Effective lighting planning considers the balance between task lighting and ambient lighting, LED fixture selection, dimming systems and lighting controls, and daylighting integration, while also accounting for code-required lighting power density limits. 

Poor lighting design, on the other hand, can result in uncomfortable work environments, unnecessary energy use, and missed efficiency incentives. Proper planning strikes the right balance between aesthetics, functionality, and compliance.

Data, Low Voltage, and Technology Integration

Modern TI projects often require seamless integration of:

• Data and voice cabling
• Wi-Fi infrastructure
• Security systems
• Access control
• AV and conferencing systems

Electrical planning must coordinate with low-voltage systems to avoid congestion, delays, and conflicts between trades. Missing this coordination often results in last-minute adjustments that derail schedules.

Phasing, Scheduling, and Occupied Buildings

Many TI projects occur in partially occupied buildings, adding complexity to scheduling and safety. Electrical work must be carefully phased to maintain power for existing tenants, minimize disruptions, and protect life safety systems. 

It’s also likely that you’ll have to comply with after-hours work restrictions depending on the building and location. Fortunately, experienced planning ensures electrical upgrades support the project timeline without impacting surrounding tenants or building operations.

Budget Control and Change Management

Electrical scope creep is a common driver of TI cost overruns. Poor initial planning can lead to unexpected panel or service upgrades, relocation of electrical infrastructure, added circuits or equipment, and extended labor hours. 

Engaging an electrical contractor early in design helps identify potential issues, align expectations, and build realistic budgets, ultimately saving time and money.
