Northern Virginia Service Context

Serving the DMV Region

Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties

Northern Virginia's commercial electrical landscape is uniquely shaped by the region's position as a major technology, government, and business hub. Loudoun County hosts the largest concentration of data centers in the world, driving demand for mission-critical electrical infrastructure with redundant power systems and massive three-phase installations. Arlington and Fairfax counties are home to hundreds of government contractors and defense firms that require secure, reliable electrical systems meeting federal facility standards. The Tysons Corner area has undergone a dramatic transformation from suburban office parks to a true urban center, with the Silver Line Metro driving demand for mixed-use developments that need sophisticated commercial electrical systems. Along the Route 28 corridor from Manassas through Centreville to Sterling, the growing technology sector is filling office parks and flex spaces that require modern data cabling and high-density power distribution. Reston Town Center continues to attract restaurants, retail, and professional offices, all competing for tenants who expect modern electrical amenities including EV charging stations, LED lighting, and smart building controls. The region's commercial real estate market commands premium lease rates, making energy efficiency upgrades particularly attractive -- a well-executed LED retrofit or power quality improvement can deliver ROI within 18 to 24 months while making properties more competitive for tenant acquisition.

Office Complex Electrical Overhaul

office
Multi-tenant office building in Tysons Corner, Fairfax County

Challenge

A 45,000 sq ft office complex built in the early 1990s was experiencing recurring breaker trips, dimming lights during peak hours, and tenant complaints about insufficient outlets for modern workstation setups. The building's original 800-amp service and outdated fluorescent lighting were driving operating costs well above market average.

Solution

AJ Long Electric performed a comprehensive electrical overhaul including a main switchgear upgrade to 1,200 amps, a full LED lighting retrofit across all three floors with occupancy sensors and daylight harvesting controls, and installation of additional 20-amp circuits to every office suite to support modern power demands.

Result

Monthly electricity costs dropped 42% within the first quarter after the retrofit. Tenant satisfaction scores improved dramatically, and the building owner secured two new long-term leases within six months, citing the modernized electrical infrastructure as a key differentiator.

Restaurant Kitchen Electrical Expansion

Upscale restaurant at Reston Town Center, Fairfax County

Challenge

A newly leased restaurant space in Reston Town Center required a complete electrical build-out for a commercial kitchen with heavy-draw equipment including a convection oven, commercial dishwasher, walk-in cooler, and hood ventilation system. The existing tenant space had only basic office-grade electrical service with no three-phase power.

Solution

We installed a 400-amp three-phase subpanel dedicated to the kitchen, ran heavy-gauge circuits for each piece of commercial kitchen equipment, added GFCI-protected outlets at all wet locations, and installed a grease hood exhaust fan on a dedicated circuit with emergency disconnect. All work was completed during a tight four-week construction timeline coordinated with the general contractor.

Result

The restaurant opened on schedule and passed its health department and fire marshal inspections on the first attempt. The owner reported zero electrical issues during the critical first six months of operation, including during peak holiday service periods.

Medical Office Three-Phase Power Installation

Medical office suite along the Dulles corridor in Sterling, Loudoun County

Challenge

A growing orthopedic practice needed to install an in-office MRI machine, digital X-ray equipment, and additional exam room lighting in their 8,000 sq ft suite. The existing single-phase 200-amp service could not support the imaging equipment's power requirements, and the practice needed dedicated isolated ground circuits to prevent electromagnetic interference.

Solution

AJ Long Electric coordinated with the building owner and Dominion Energy to bring three-phase power to the suite, installed a new 600-amp three-phase distribution panel, ran isolated ground circuits for all imaging equipment, and added dedicated UPS-backed circuits for the practice's electronic health records servers.

Result

The orthopedic practice successfully brought diagnostic imaging in-house, reducing patient referral wait times from weeks to same-day. The clean power installation eliminated the electromagnetic interference issues that had plagued a previous attempt by another contractor.

Retail Strip Mall LED Retrofit and Parking Lot Lighting

retail
Retail center on Route 28 in Manassas, Prince William County

Challenge

A 12-unit strip mall with a large parking lot was spending over $4,200 per month on electricity, much of it wasted by aging metal halide parking lot fixtures and outdated T12 fluorescent lighting in tenant spaces. Several parking lot lights had failed entirely, creating dark spots that tenants flagged as a safety and liability concern.

Solution

We replaced all 24 parking lot pole fixtures with commercial-grade LED units featuring photocell and timer controls, retrofitted interior lighting in common areas and vacant units with LED tubes and new fixtures, and installed a centralized lighting control panel for the property management company to manage exterior lighting schedules remotely.

Result

The property's combined electricity bill dropped to under $1,800 per month, a savings exceeding 57%. The improved parking lot lighting increased foot traffic to evening-hour tenants, and the property qualified for over $8,000 in Dominion Energy commercial rebates.

Permits & Compliance

Permit & Jurisdiction Guide

Permit requirements for commercial services vary by county. We handle the entire permitting process for you.

Fairfax County

Permit Required

Permit Process

Fairfax County requires commercial electrical permits for all new installations, modifications, and tenant build-outs. Applications are submitted through the Land Development Services portal, and commercial permits typically require plan review taking 5-10 business days. A licensed master electrician must be listed on the permit, and inspections must be scheduled at each phase of work.

Inspection Notes

Fairfax commercial inspectors conduct rough-in and final inspections. They verify conduit fill ratios, proper fire-stopping at wall and floor penetrations, NEC-compliant wire sizing for commercial loads, and correct emergency lighting placement per the approved plan. Three-phase installations receive additional scrutiny for phase balancing and disconnecting means.

Special Requirements

Commercial plan review required for all tenant build-outs exceeding $5,000 in electrical work
Fire marshal approval required for fire alarm system modifications
ADA compliance verification for all public-facing spaces

Loudoun County

Permit Required

Permit Process

Loudoun County processes commercial electrical permits through the Department of Building and Development with typical plan review times of 7-14 business days for commercial projects. The county's rapid growth along the Route 28 and Dulles corridors means inspectors are in high demand, so scheduling inspections early is critical to maintaining project timelines.

Inspection Notes

Loudoun commercial inspectors pay close attention to data center-grade electrical work given the county's concentration of data facilities. They verify proper grounding and bonding for sensitive equipment, conduit specifications, and generator transfer switch installations.

Special Requirements

Data center and mission-critical facility permits require additional engineering documentation
Separate mechanical and electrical permits required for HVAC-related electrical work
Commercial projects in the Route 28 corridor may require traffic management plans for exterior work

Prince William County

Permit Required

Permit Process

Prince William County commercial electrical permits are processed through the Development Services department. Plan review for commercial projects typically takes 5-10 business days. The county offers expedited review for an additional fee, which can reduce turnaround to 2-3 business days for time-sensitive projects.

Inspection Notes

Prince William commercial inspectors verify NEC compliance, proper labeling of all commercial panels and disconnects, and correct sizing of feeders and branch circuits. They require accessible panel directories and may request load calculations for larger installations.

Special Requirements

Contractor must hold a valid Virginia Class A contractor license for commercial projects over $10,000
Exterior signage electrical requires separate sign permits
Parking lot lighting plans must meet county dark-sky ordinance requirements

Arlington County

Permit Required

Permit Process

Arlington County has a rigorous commercial permit process managed by the Inspections Services Division. Commercial electrical permits require architectural and engineering plan submissions, with plan review typically taking 10-15 business days. Arlington's dense urban environment and proximity to federal facilities mean commercial electrical work may require additional security or coordination considerations.

Inspection Notes

Arlington commercial inspectors are among the most detail-oriented in Northern Virginia. They verify proper separation of low-voltage and line-voltage systems, check for compliance with the latest NEC edition adopted by the state, and require thorough documentation of all commercial installations including as-built drawings.

Special Requirements

Commercial projects in the Rosslyn-Ballston corridor may require after-hours work to avoid pedestrian disruption
Historic district overlay zones require additional architectural review for exterior electrical modifications
All commercial permits expire after 180 days if work is not completed and inspected

By Home Type

Commercial Services by Housing Type

Different home styles have unique electrical characteristics. Select your housing type to see specific considerations.

Office Building Homes

Common Issues

Insufficient outlets and circuits for modern open-plan workstation layouts with multiple monitors and devices per desk
Aging fluorescent lighting causing eye strain, headaches, and high energy bills compared to modern LED alternatives
Inadequate structured cabling infrastructure for high-speed data networking and VoIP phone systems
Overloaded panels from decades of incremental tenant additions without proper load calculations

Special Considerations

Office buildings throughout the Tysons Corner, Reston, and Arlington business districts often require electrical work coordinated around occupied tenant spaces. Phased installation is critical to avoid disrupting business operations, and after-hours or weekend scheduling is frequently necessary. Many office buildings in Northern Virginia serve government contractors with sensitive data requirements, necessitating isolated power circuits and proper grounding for secure computing equipment.

FAQs

Frequently Asked Questions

Get answers to common questions about our commercial services services.

Do you work on commercial properties and businesses?

Yes, we serve small to medium commercial properties throughout Northern Virginia including offices, retail stores, restaurants, warehouses, and medical facilities. We're familiar with commercial code requirements and work efficiently to minimize disruption to your business operations.

Can you work after hours to avoid disrupting our business?

Absolutely. We offer flexible scheduling including evenings, early mornings, and weekends for commercial clients who need work done outside regular business hours. We understand that every hour of downtime affects your bottom line.

What is a tenant build-out or fit-out?

A tenant build-out involves modifying a commercial space for a new tenant's specific needs. This typically includes adding outlets and circuits, installing lighting layouts, running data cabling, and ensuring adequate power for the business's equipment and operations.

Can you help reduce our commercial electricity bills?

Yes, we offer LED lighting retrofits that can reduce lighting energy consumption by 50-75%. We also identify power quality issues that waste energy and recommend efficiency improvements. Many upgrades qualify for utility rebates that reduce your investment cost.

Do you install data and network cabling?

Yes, we install structured cabling including Cat6 and Cat6a for data networks, as well as low-voltage wiring for phone systems, security cameras, and access control. Proper cabling infrastructure is essential for modern business operations.

How do you handle emergency commercial repairs?

We offer priority emergency service for commercial clients experiencing power outages or safety issues. A business without power is losing money, so we respond quickly and work efficiently to restore your operations as fast as possible.

Can you bring our older building up to current code?

Yes, we perform code compliance upgrades including panel updates, GFCI protection, proper grounding, emergency lighting, and exit sign installations. We can also prepare your building for inspections required for insurance, lease agreements, or renovations.

Do you provide commercial maintenance contracts?

Yes, we offer ongoing maintenance contracts for commercial clients that include scheduled inspections, priority emergency response, and preventive maintenance for lighting, panels, and emergency systems. Maintenance contracts help avoid unexpected failures and keep your facility in continuous compliance with safety codes.

What is three-phase power and does my business need it?

Three-phase power delivers electricity through three alternating currents, providing more consistent power for heavy equipment like commercial HVAC systems, industrial machinery, and large server rooms. Most commercial buildings in Northern Virginia are supplied with three-phase power. We handle all three-phase installations, upgrades, and troubleshooting.

Can you install EV chargers for commercial parking lots?

Yes, we install Level 2 and Level 3 EV charging stations for commercial properties, including networked chargers that allow you to manage billing and usage. Commercial EV charging is increasingly expected by tenants, employees, and customers, and may qualify for federal tax credits and utility incentive programs.

How do LED retrofits reduce commercial operating costs?

LED retrofits replace outdated fluorescent or HID fixtures with energy-efficient LEDs that use 50-75% less electricity and last 3-5 times longer, dramatically reducing both energy bills and maintenance costs. Many Virginia utility companies offer rebates that offset a significant portion of the retrofit investment.

Do you handle fire alarm system electrical work?

We handle the electrical wiring and power connections for fire alarm systems and coordinate with fire alarm specialists for system programming and monitoring. We ensure fire alarm circuits meet code requirements for dedicated power, battery backup, and proper integration with your building's electrical system.
