Building an accessory dwelling unit, garage apartment, in-law suite, or backyard cottage requires a properly designed electrical system that meets dwelling unit code requirements. Unity Power & Light handles the complete electrical scope for ADU projects throughout Aiken County, from initial load calculations and metering decisions through rough-in wiring, panel installation, and final inspection.
ADU electrical work is more complex than standard outbuilding wiring because the space is classified as a dwelling unit under the National Electrical Code. That means kitchen circuits, bathroom GFCI protection, bedroom AFCI protection, smoke detectors, and proper service sizing are all required. We know these requirements and build them into every ADU project.
We calculate the electrical load for your ADU based on its size, appliances, HVAC system, and intended use. This determines panel size, feeder sizing, and whether your main panel can support the additional load.
Shared meter with a sub-panel from the main house, or separate meter with its own utility account. We help you decide which approach makes sense for your situation and handle the utility coordination.
60-amp to 200-amp panels sized for the ADU's specific needs. Includes proper grounding, main breaker protection, and circuit capacity for all planned loads plus future expansion.
All branch circuit wiring for outlets, switches, lighting, kitchen appliance circuits, bathroom circuits, HVAC circuits, and dedicated appliance circuits. Code-compliant installation from panel to every device.
GFCI outlets in kitchens, bathrooms, and outdoor locations. AFCI breakers for bedroom circuits. Hardwired, interconnected smoke detectors and carbon monoxide detectors.
We pull the electrical permit, schedule rough-in and final inspections, and handle any corrections. The permit process is part of our service, not an add-on.
Each type has specific electrical considerations for feeder routing, panel placement, grounding requirements, and utility coordination. We assess your specific project and provide a detailed scope of work and flat-rate quote.
