Master Electrician & Class B Licensed

Commercial Electrician in Portsmouth, VA

Downtown Portsmouth houses two distinct generations of commercial buildings. Along the High Street Corridor, the state register describes a district dominated by two-story brick commercial buildings with first-floor storefronts. A 2026 boundary increase added mostly mid-century office buildings of two to seven stories. A fit-out in one rarely resembles a fit-out in the other.

Castles Electrical takes on Portsmouth commercial projects from tenant fit-outs and service upgrades to lighting and standby power. We hold a Class B Contractors license, work with 480-volt three-phase service, and our own licensed electricians do the work.

01 — Portsmouth Conditions

Turn-of-the-Century Storefronts and Mid-Century Office Floors

The two-story brick storefront

A building put up for a shop around 1900 was never sized for a commercial kitchen, a salon’s equipment, or a modern lighting package. When a new tenant moves in with heavier loads, the first question is whether the existing service can carry them. Some storefronts also share the building with an upstairs apartment or office on the same service.

We look at how the building is metered and fed before recommending changes, and we coordinate any service or metering work with Dominion Energy.

The mid-century office building

Mid-century office floors have their own distribution, so the work is a tenant floor being reworked: panels, branch circuits, and lighting brought into line with what the new occupant runs, while the floors above and below stay occupied.

Exterior lighting and signs in the design overlay

Portsmouth’s Certificate of Appropriateness application applies in the Downtown Design Overlay District and the city’s historic districts, and its checklist includes installing or modifying exterior lighting and signs. The registration listing alone does not trigger that review; city planning confirms whether a given address is included. For a covered building, a new lit sign or storefront lighting may require a design review step, and we time the electrical rough-in to follow the approved design.

When a storefront changes what it is used for

A space that was a quiet retail shop and becomes a cafe, a gym, or a salon changes more than its furniture. The new use brings different equipment, more receptacles, and often different lighting, including the exit and emergency lighting the building needs for its occupants. We work from the new tenant’s equipment list and the architect’s plans, so the circuits, panel space, and lighting match how the space will actually be used.

Lighting that fits the building

Inside, older storefronts often still have a patchwork of fixtures from past tenants. An LED retrofit can bring the whole floor onto consistent fixtures and controls, and in a mid-century office floor it usually goes hand in hand with reworking the branch circuits. Outside, building-mounted lighting on a covered facade is planned with the design review in mind.

03 — Fire Inspections

Annual Fire Inspections and Emergency Lights

Portsmouth’s Fire Marshal’s Office says its inspectors visit businesses, hotels, industrial and medical facilities, and schools annually to ensure protective safety systems, such as fire alarm systems and portable extinguishers, are in place.

Virginia’s 2021 Statewide Fire Prevention Code, which governs maintenance and operation of existing buildings, adds a requirement that touches the electrical side. Required emergency lighting that uses battery-powered emergency lights, exit signs, or both has to be tested annually for proper operation for the time the building code required when the units were installed, and the owner keeps written records of those tests for at least two years.

In a downtown storefront or a mid-century office floor, emergency lights and exit signs may date back several tenants. When an emergency light or exit sign fails, we repair or replace the unit and check the circuit that supplies it. Fire alarm systems and the inspections themselves stay with the fire marshal’s office and your fire alarm contractor.

04 — Kitchen Hoods

Power Shutoff Under a Commercial Kitchen Hood

When a restaurant build-out includes a hood with a fire suppression system over the cooking line, that system is tied to the electrical work. Virginia’s 2021 Construction Code requires that the fire suppression system automatically shut down the fuel or electrical power supply to the cooking equipment, and that the reset be manual.

For electric ranges, fryers, and other cooking equipment, this means the circuits feeding the line must be wired so the suppression system can cut them off, using the shutoff method the hood and suppression design calls for. Knowing which equipment sits under the hood, and which does not, shapes how the panel and circuits are laid out.

We wire the equipment circuits for that shutoff and coordinate with your hood and suppression contractors, who install and certify their systems.

05 — EV Chargers

EV Chargers for Customer or Staff Parking

For businesses covered by the ADA, adding EV chargers also brings accessibility planning. The U.S. Access Board says entities covered by the ADA must provide EV charging stations that are accessible to and usable by people with disabilities, even though the current standards do not name chargers specifically.

Its technical guidance recommends an accessible charging space at least 11 feet wide and 20 feet long, with a 5-foot access aisle, on an accessible route, and operable parts no higher than 48 inches. It advises against converting existing accessible parking spaces to EV-only charging, since that changes the required count of accessible spaces. The Board published a proposed rule on EV charger accessibility in September 2024; as of September 2026, it is not yet a final requirement.

Charger locations come first, then the service capacity and the circuits to reach them. We plan the electrical side around the layout you and your site designer settle on.

08 — FAQS

Portsmouth Commercial Electrical FAQs

Who handles design review for a new sign?+

Usually the owner, the tenant, or the sign company files for the sign itself. We provide the circuit and power connection to the sign, handle our electrical permit, and place the rough-in to match the approved design.

Can an older storefront support a restaurant kitchen?+

Sometimes. We add up the kitchen equipment, lighting, and HVAC against the existing service, and if it cannot carry the load, we plan the upgrade and the utility coordination.

Can we add heavy equipment when an upstairs unit shares the service?+

It depends on the existing metering and total load. We measure both and explain the options, such as a service upgrade or separating the services, with the utility’s involvement where it applies.

Does a mid-century office floor need a new meter for a new tenant?+

Not necessarily. It depends on how the building is metered today and what the lease requires. We check the existing arrangement during the site walk before recommending metering changes.

What should I have ready before the walk-through?+

Access to the electrical room or panel, a list of the equipment the space will run, any drawings from the architect or landlord, and a note of any exterior lighting or sign changes.
