Commercial tenant improvements can completely transform a property. An empty shell can become a restaurant. An outdated office can become a modern professional workspace. A retail location can be redesigned for a new brand, and a warehouse can be adapted for an entirely different type of operation.
But behind the new walls, finishes, lighting, equipment and technology is something that can determine whether the entire project works as intended: The electrical system.
Electrical planning is one of the most important, and sometimes underestimated, parts of a commercial tenant improvement project.
For property owners, general contractors, developers and tenants throughout Reno, Sparks and Northern Nevada, involving an experienced commercial electrical contractor early will help identify potential electrical limitations, prevent costly changes during construction, improve safety and keep the project moving toward completion.
For many tenant improvement projects, Enhanced Electrical can take that involvement a step further through a design-build electrical approach. When Enhanced Electrical performs the electrical work, our team also provides the electrical consultation, required electrical calculations and electrical drawings for permit submission, potentially eliminating the need to hire a separate electrical engineer and reducing overall project costs.
If you're planning a commercial tenant improvement or remodel in the Reno-Sparks area, involving Enhanced Electrical early can help you determine the most efficient path from electrical planning and design through permitting and installation.

A commercial tenant improvement, often referred to as a TI or tenant build-out, is the modification of an existing commercial space to accommodate the requirements of a new or existing tenant.
Tenant improvements can range from relatively straightforward changes to major renovations.
Projects may include:
Every change can affect the electrical requirements of the property. That's why electrical planning shouldn't begin after construction has already started.
It should be part of the project from the beginning.
Before designing the electrical requirements for a tenant improvement, you first need to understand what is already there. An existing commercial building may have been designed decades ago for an entirely different type of tenant.
The first question isn't simply: “What does the new tenant need?”
It's also: “Can the existing electrical system support it?”
A commercial electrical assessment may evaluate:
This becomes particularly important when changing how a commercial property will be used.
An office, for example, may have relatively modest electrical requirements compared with a restaurant filled with refrigeration, cooking and ventilation equipment. Likewise, converting warehouse space into a manufacturing operation may introduce significant new electrical loads.
Discovering those limitations before construction begins is far better than discovering them after walls, ceilings and finishes have already been installed.
Modern businesses use more electricity than ever.
Computers, servers, commercial appliances, HVAC systems, specialized equipment, security systems, displays, chargers and automation technologies can dramatically increase electrical demand.
During a tenant improvement, the electrical contractor needs to understand both the tenant's current requirements and reasonable future needs. Depending on the business, those electrical loads can vary considerably.
Office spaces may require power for computer workstations, conference-room technology, servers, networking equipment, break-room appliances, charging stations, security systems and HVAC equipment.
Retail spaces may need electrical capacity for point-of-sale systems, display lighting, exterior signage, refrigeration, security systems, digital displays and specialty equipment.
Restaurants and food-service businesses can introduce significant loads from refrigerators, freezers, ovens, dishwashers, food-preparation equipment, exhaust and ventilation systems, lighting, point-of-sale systems and HVAC equipment.
Warehouses and industrial facilities may require electrical systems supporting machinery, conveyor systems, welders, compressors, production equipment, high-bay lighting, specialized controls, three-phase equipment and charging systems.
Understanding these requirements early allows the electrical design to be properly coordinated with the rest of the project.
This is an area where the right commercial electrical contractor can potentially simplify the project considerably.
In a traditional construction process, a separate electrical engineer may be hired to develop the electrical design, perform electrical calculations and prepare drawings before the electrical contractor begins installation.
For qualifying projects, Enhanced Electrical can manage both the electrical design and installation, creating a more streamlined design-build process from planning through completion. That includes:
The advantage is integration.
The electrical contractor evaluating the existing infrastructure and designing the electrical solution is also the contractor responsible for building it. This helps reduce handoffs between separate parties, improve communication and constructability, simplify project coordination and potentially reduce overall design costs.
In some situations, it may also eliminate the need to hire a separate electrical engineer for the electrical work being performed by Enhanced Electrical, creating meaningful savings for the customer.
There is an important limitation: as an electrical contractor, Enhanced Electrical can only provide electrical design services for electrical work that we self-perform. Projects requiring engineering services beyond that scope may still require a licensed electrical engineer or other design professional.
For the right commercial tenant improvement, however, a design-build approach can provide a much more efficient path from concept to permit to construction.
One of the most important components of any commercial tenant improvement is the electrical panel.
Older commercial properties may have panels that were perfectly adequate for the building's original use but aren't designed to support today's electrical demand.
Potential warning signs include limited available breaker spaces, frequently tripping breakers, outdated electrical equipment, insufficient service capacity, evidence of overheating, corrosion, aging components or numerous previous modifications.
A commercial panel or service upgrade may be necessary when the new tenant introduces significantly greater electrical demand.
Planning this early matters, as discovering halfway through a project that the electrical service or panel requires an upgrade can affect both the project budget and construction schedule.
One of the most common frustrations in newly remodeled commercial spaces is discovering that outlets aren't located where they're actually needed.
Electrical planning should follow the operational layout of the business.
Consider questions such as:
A few strategically planned circuits during construction can be far less expensive and disruptive than modifying a completed space later.
Commercial tenant improvements can involve general contractors, electricians, HVAC contractors, plumbers, framers, drywall contractors, architects, engineers, low-voltage contractors, security companies, equipment vendors and interior designers.
Electrical work interacts with nearly all of them.
For example, an electrical contractor may need to coordinate HVAC power requirements with the mechanical contractor. Lighting placement may need to be coordinated with ceiling systems and interior design. Commercial equipment may require manufacturer specifications before electrical circuits can be properly designed.
Early coordination will help reduce conflicts, change orders and unnecessary delays.
This is another potential advantage of a design-build electrical approach: electrical design and field execution are closely connected rather than being treated as separate processes.
For general contractors, having an experienced Reno commercial electrical contractor like EES involved early will make project coordination significantly easier.
Lighting has a major impact on how a commercial space looks, feels and functions.
A tenant improvement is an excellent opportunity to rethink the lighting design rather than simply replacing existing fixtures.
Modern commercial LED lighting can provide several advantages, including:
The right solution depends heavily on the type of property.
A retail store may need accent and display lighting. An office may prioritize comfortable, consistent illumination. A warehouse may benefit from high-efficiency LED high-bay fixtures, while a restaurant may require multiple lighting zones to create different environments throughout the space.
The goal shouldn't simply be to light the space.
Lighting should be designed around how people will actually use it.
Today's commercial spaces depend heavily on technology.
Tenant improvement planning may need to accommodate Wi-Fi access points, data cabling, telecommunications, security cameras, access-control systems, audio/video systems, point-of-sale equipment, building automation and digital displays.
While many of these systems use low-voltage infrastructure, they still need to be coordinated with electrical power and the overall construction plan.
Planning these requirements before walls and ceilings are closed can make installation cleaner, easier and more cost-effective.
Emergency lighting and illuminated exit signs are critical components of commercial building safety.
During a remodel, walls, doors, hallways and occupancy patterns may change. That means the existing emergency-lighting layout may no longer be appropriate for the renovated space.
Tenant improvement planning should evaluate whether emergency and exit lighting needs to be relocated, expanded or upgraded as part of the project.
These systems may not be the most visible part of a commercial remodel, but they can become some of the most important during an emergency.
A tenant improvement provides an excellent opportunity to improve energy efficiency because electrical systems are already being modified.
Potential improvements may include:
Rather than viewing electrical improvements solely as a construction expense, property owners can consider how today's upgrades may affect operating costs, reliability and the long-term usefulness of the property.
Commercial properties evolve. Tenants expand. Technology changes. Equipment gets replaced. Businesses add new services.
A well-designed electrical system should consider reasonable future requirements.
Future-proofing doesn't necessarily mean installing everything today.
It means making smart decisions during construction that can make tomorrow's changes easier.
Commercial electrical work must meet applicable electrical and building requirements. Depending on the scope of the project, electrical work may require plans, permits and inspections.
Requirements can vary according to the scope of work, property type, occupancy, electrical loads, equipment being installed, service changes and local jurisdiction.
This is another reason to involve a qualified commercial electrical contractor early.
For qualifying projects where Enhanced Electrical will self-perform the electrical installation, our design-build capabilities can include electrical calculations and preparation of electrical drawings for permit submission.
This can help create continuity between the electrical design submitted for the project and the work ultimately performed in the field.
Electrical costs can represent a meaningful portion of a commercial build-out.
Waiting until late in the design process to determine electrical requirements can create unpleasant budget surprises.
A better approach is to identify major electrical requirements during initial project planning.
Potential cost factors include service upgrades, electrical panels, new circuits, rewiring, lighting, equipment connections, emergency systems, controls, data infrastructure, specialty equipment and permit requirements.
An early electrical assessment can help property owners and contractors understand the likely scope before major construction decisions are finalized.
And when a design-build approach is appropriate, combining electrical design and installation under one contractor may provide another opportunity to simplify the project and reduce costs.
Not every tenant improvement takes place in an empty building.
Sometimes remodeling occurs while businesses remain operational. In those situations, electrical planning becomes even more important.
Electrical contractors may need to coordinate temporary power interruptions, scheduled shutdowns, work around operating hours, phased construction, equipment transitions and safety barriers.
The objective is to complete the required work while minimizing unnecessary disruption to employees, customers and business operations.
Enhanced Electrical understands that downtime can directly affect a company's bottom line and works with commercial clients to coordinate electrical projects around operational requirements.
Before construction begins, property owners and contractors should consider:
1. Existing electrical system
Is the current electrical infrastructure in good condition?
2. Available capacity
Can the electrical service and panels support the new tenant?
3. Electrical design
Can a design-build approach simplify the project and reduce the need for separate electrical design services?
4. Equipment
What specialized equipment will require power?
5. Dedicated circuits
Which systems require their own circuits?
6. Outlet locations
Do receptacles match the actual layout and workflow?
7. Lighting
Does the new design require different fixtures, controls or lighting zones?
8. Emergency systems
Do exit signs or emergency lights need to be relocated or added?
9. Technology
Have data, security and communication systems been coordinated?
10. Energy efficiency
Are there opportunities to improve lighting or electrical efficiency?
11. Future expansion
Can the electrical design accommodate reasonable future growth?
12. Permits and inspections
What local requirements apply to the project?
13. Construction coordination
Have electrical requirements been coordinated with the general contractor and other trades?
Addressing these questions early can help create a smoother, more predictable tenant improvement process.

Plan it right. Design it right. Build it right. Power it right.
As electric vehicles (EVs) continue to surge in popularity, homeowners are increasingly turning their garages into personal charging stations. However, with this convenience comes the need for heightened safety measures.
The National Electrical Code (NEC), which sets the standards for electrical installations in the US, has undergone significant updates to address the unique demands of EV charging. In this post, we'll explore the shift away from outdated practices like using range receptacles, the introduction of mandatory GFCI protection, the emerging requirement for EV-rated receptacles in the 2026 NEC, and the critical role of electrical load calculations in ensuring a safe setup. Whether you're a new EV owner or an electrician, understanding these changes can prevent hazards and keep your home powered efficiently.
Historically, many early EV adopters relied on NEMA 14-50 outlets—commonly known as range receptacles—for Level 2 charging. These 50-amp outlets, designed primarily for electric stoves or dryers, were a convenient plug-and-play option since they matched the voltage and amperage needs of many portable EV chargers. However, this approach has proven problematic over time.
The core issue lies in the design and rating of these receptacles. Unlike stoves, which operate intermittently, EV chargers often draw a continuous heavy load—up to 40 amps or more for hours on end. Standard range outlets aren't built for this sustained use or the frequent plugging and unplugging typical of daily EV charging. Over time, this can lead to loose connections, poor heat dissipation, and arcing at the contacts. Inferior materials in cheaper outlets exacerbate the problem, causing melting, charring, and in worst-case scenarios, fires.
Real-world incidents highlight the dangers. Numerous reports detail melted NEMA 14-50 outlets sparking garage fires, with damage ranging from scorched walls to near-total home losses. For instance, EV owners have shared stories of outlets failing dramatically after months of use, often due to non-industrial-grade components that can't handle the thermal stress. These failures aren't isolated; they've become a common topic in EV communities, prompting warnings from experts to opt for hardwired installations or high-quality, EV-rated outlets instead.
The lesson? What seemed like a simple solution in the early days of EVs has revealed itself as a ticking time bomb, pushing code updates to prioritize safety.
Recognizing these risks, the 2023 NEC introduced key changes in Article 625, which governs Electric Vehicle Power Transfer Systems. One of the most significant is Section 625.54, requiring Ground Fault Circuit Interrupter (GFCI) protection for all receptacles used in EV charging. This applies to cord-and-plug-connected Equipment (EVSE), ensuring that any ground faults—such as those caused by moisture, damaged cords, or faulty wiring—are detected and interrupted almost instantly, preventing shocks or fires.
Previously, GFCI was often recommended but not universally mandated for EV outlets. Now, it's required for both indoor (like garages) and outdoor installations, expanding on earlier codes that focused on wet locations. For hardwired chargers, GFCI is only necessary if specified by the manufacturer, but the code emphasizes dedicated circuits and overcurrent protection to match.
Looking ahead, the 2026 NEC builds on this by extending GFCI requirements to all outlets, including hardwired EVSE, further closing potential safety gaps. These updates reflect a broader trend: as EVs become mainstream, codes are evolving to treat charging infrastructure as a dedicated, high-demand system rather than a repurposed appliance outlet.
A major upcoming change in the 2026 NEC (published in late 2025) is found in Section 625.44 (Equipment Connection). This section now requires that all non-locking 30A, 50A, and 60A receptacles used for portable or hand-fastened cord-and-plug-connected EVSE must be specifically listed for EVSE (Electric Vehicle Supply Equipment) or WPTE (Wireless Power Transfer Equipment) use. This directly addresses the fire risks from generic range receptacles under continuous heavy loads.
Additionally, the 2026 NEC prohibits installing a 50A receptacle on a 40A branch circuit—a common practice that contributed to overheating issues.
While the 2026 NEC is now available and becomes effective in many jurisdictions starting in 2026 (with some delays or grace periods), adoption varies by state and locality. In Reno, Nevada (Washoe County), the 2023 NEC (with local amendments) is currently in effect, and full adoption of the 2026 edition is not yet required. That said, using an EV-rated receptacle (such as those from Hubbell or Leviton specifically marked for EV charging) is strongly recommended even under current codes due to the documented fire risks.
Before plugging in that new charger, one non-negotiable step is conducting a thorough electrical load calculation. This assesses whether your home's electrical panel and service can handle the additional demand without overloading circuits, which could lead to tripped breakers, overheating wires, or worse.
If your calculation shows you're over capacity, options include upgrading your panel, using a load-sharing device, or opting for a lower-amperage charger. Always have a licensed electrician perform this—it's not just code compliance; it's about safety.
The NEC's updates for EV charging underscore a simple truth: EVs are transforming how we power our lives, but safety can't be an afterthought. Moving beyond range receptacles, embracing GFCI protection (and soon EV-rated receptacles per 2026 NEC Section 625.44), and prioritizing load calculations are essential steps to mitigate risks like fires and overloads.
If you're planning an installation, consult a qualified electrician familiar with the latest codes—your home (and your EV) will thank you. Stay tuned for more on emerging tech like bidirectional charging, and drive safe!
