Tenant Improvement

Tenant Improvement Wiring & Commercial Service Upgrades

Austin's commercial real estate market turns over tenant spaces regularly, and nearly every new tenant has different electrical requirements than the previous occupant. A restaurant moving into a former retail space needs heavy-gauge circuits for commercial kitchen equipment. A medical office needs dedicated circuits for imaging equipment and proper grounding. A co-working space needs high-density outlet and data outlet distribution across an open floor plan. Getting the electrical rough-in right during a TI buildout avoids expensive change orders and failed inspections later.

We work with general contractors and directly with tenants and landlords on TI electrical scopes. Our process starts with reviewing the existing panel and service capacity against the incoming tenant's load requirements, identifying whether a service upgrade is needed before the project starts, and then executing the rough-in, trim, and inspection schedule to match the GC's timeline. We pull commercial permits from the City of Austin and Travis County and manage the inspection process through to final sign-off.

Commercial LED lighting retrofit and EV charging Austin

Lighting & EV Infrastructure

Commercial LED Retrofits & Parking Lot EV Charging Stations

Commercial LED lighting retrofits are one of the most straightforward ways for building owners to reduce operating costs. Replacing T8 or T12 fluorescent fixtures with LED equivalents cuts lighting energy consumption substantially and reduces maintenance labor — LED tubes and fixtures last significantly longer than fluorescent lamps. We handle both direct-wire (bypass ballast) LED retrofits and plug-and-play conversions across office spaces, warehouses, parking garages, and retail floor areas.

EV charging infrastructure for commercial parking lots is growing in demand across Austin as more employees and customers arrive in electric vehicles. Commercial Level 2 charging stations operate on 208V or 240V circuits and range from 7.2kW single-port units to dual-port 19.2kW stations. Level 3 DC fast chargers (DCFC) require higher-amperage three-phase circuits and significant panel capacity. We size the electrical infrastructure, install the circuits, and coordinate with ChargePoint, Blink, and other commercial EVSE providers. Austin Energy offers commercial incentives for qualifying EV infrastructure projects that we help customers document.

Compliance & Scheduling

Code Compliance Work & After-Hours Commercial Scheduling

Commercial properties change hands, undergo inspections, and face compliance requirements that residential properties don't. A property sale, a change of use, a fire marshal inspection, or a new commercial lease can surface electrical code deficiencies that need to be corrected before an occupancy certificate is issued. We perform electrical inspections, produce a written list of observed deficiencies referenced to the applicable NEC section, and then execute the corrections under permit.

Many commercial clients — particularly restaurants, retail operations, and medical offices — cannot afford downtime during business hours for electrical work. We routinely schedule commercial projects for evenings and weekends to avoid disrupting operations. After-hours scheduling is coordinated during the estimate process; we don't treat it as an exception that requires negotiation. If your business operates during normal hours, we work around it.

Common Questions

Commercial Electrical FAQs

What property owners, managers, and GCs ask when starting a commercial electrical project in Austin.

Do you work on commercial buildings?

Yes. Voltage Electric Co. handles both residential and commercial electrical work in the Austin metro. On the commercial side, we work primarily on light commercial projects: office and retail tenant improvements, restaurant and food service electrical, medical and dental office wiring, small industrial and warehouse spaces, and commercial service upgrades up to 800 amps. We don't pursue large-scale industrial or high-voltage utility work. If you're unsure whether your project falls within our scope, call or send us a project description — we'll tell you honestly whether it's a good fit.

What commercial electrical services do you offer?

Our commercial services include tenant improvement wiring and rough-in, commercial service and panel upgrades, three-phase circuit installation, LED lighting retrofits, commercial EV charging station installation, emergency and exit lighting systems, code compliance inspections and corrections, sub-panel additions, dedicated equipment circuits, and commercial permit management through the City of Austin. We also provide after-hours service for occupied commercial properties where daytime work would disrupt operations.

Can you handle after-hours commercial work?

Yes, and this is a standard part of how we approach commercial projects. Restaurants, retail stores, medical offices, and many other commercial operations can't shut down during business hours for electrical work. We schedule evening and weekend installation windows during the estimate process so the timeline is built around your operation, not ours. After-hours commercial rates reflect the scheduling premium, which we disclose clearly in writing as part of the estimate.

Do you pull commercial permits?

Yes. We pull all required permits for commercial electrical work in the City of Austin, Travis County, and surrounding jurisdictions. Commercial electrical permits require a licensed master electrician of record, a completed permit application, and in many cases a one-line diagram and load calculation submitted with the application. We prepare and submit this documentation and manage the inspection schedule through to final sign-off. Unpermitted commercial electrical work creates serious liability for building owners and tenants — we don't perform it under any circumstances.

What's the difference between commercial and residential electrical work?

The core difference is in the NEC code articles that apply, the wiring methods used, and the service voltages involved. Commercial buildings in Texas are governed by NEC Article 230 for services and NEC Article 210/215 for feeders and branch circuits, but many commercial code requirements differ from residential — conduit wiring methods are required in most commercial applications rather than NM-B (Romex) cable, three-phase power is common, and service voltages are often 208/120V three-phase rather than the 240/120V split-phase service in residential construction. Permitting and inspection requirements are also more extensive. Our electricians are trained and licensed for both environments.
