Types of Accessory Dwelling Unit Electrical Installation Projects

We handle a variety of electrical installation projects specifically designed for different types of accessory dwelling units. Each project requires tailored wiring, safety measures, and compliance with local codes and standards to ensure functionality and safety.

New Detached ADU Wiring


For new detached ADUs, we focus on designing a complete electrical system from the ground up. This includes running service lines from the main panel to the ADU, installing subpanels, and ensuring all circuits meet load demands for lighting, outlets, appliances, and HVAC.



We use modern wiring methods such as copper conductors and conduit to protect wiring from physical damage. GFCI and AFCI breakers are installed to comply with California’s strict electrical safety codes. We also provide options for energy-efficient LED lighting, programmable thermostat systems, and EV charging stations if needed.

Garage Conversion Electrical Upgrades


When converting garages into living spaces, electrical upgrades are essential to support increased power needs and code requirements. We retrofit existing wiring, upgrade outdated panels, and add circuits for kitchenettes, smart home devices, and fire safety systems.



Our experience with converted garages includes relocating outlets, upgrading lighting fixtures, and ensuring proper grounding and bonding. We also install dedicated circuits for appliances and HVAC to prevent overloads. Compliance with fire and building codes for these conversions is strictly followed.

Junior ADU (JADU) Electrical Solutions


JADUs require a different approach due to their smaller scale but still need fully functional electrical systems. We offer streamlined wiring plans focusing on efficient use of space and energy.



Electrical solutions for JADUs include compact breaker panels, energy-saving lighting, and compliant receptacles and switches. We ensure all work supports safety and comfort while addressing the limited square footage. These setups often integrate with the main home's existing service but maintain independent control and safety features.

Our Electrical System Installation Process for ADUs

We follow a precise and structured approach to install electrical systems in ADUs. Each step is designed to meet safety standards, optimize energy efficiency, and integrate seamlessly with modern ADU designs and garage conversions in Thousand Oaks. Our focus is on delivering a reliable and code-compliant electrical infrastructure tailored to your ADU’s unique needs.

Site Assessment and Planning


Our process begins with a thorough site assessment to understand the specific electrical requirements of your ADU. We evaluate the property's electrical capacity, existing infrastructure, and any potential challenges related to layout, grounding, or panel access.


We collaborate with you and your ADU builder to determine the number and type of outlets, lighting fixtures, and appliances needed. This stage also involves assessing energy-efficient options, such as LED lighting and smart home components, which we incorporate to enhance functionality and reduce costs.


By carefully planning cable routes and load distribution, we ensure your ADU’s electrical system supports current needs and allows future upgrades without extensive rewiring.


Design and Permitting


We create detailed electrical system designs that comply with California’s building codes and the National Electrical Code (NEC), ensuring safety and code compliance.


Our designs specify wire gauges, panel sizes, circuit breaker capacities, and locations for switches, outlets, and fixtures. We also incorporate dedicated circuits for HVAC units, kitchen appliances, and any smart home integration typical of modern ADUs.


Once the design is finalized, we handle all necessary permitting with local authorities in Thousand Oaks. Our ADU permit application and processing service includes submitting plans for review and scheduling inspections, reducing delays and ensuring a smooth approval process.


Professional Electrical Installation


Our licensed electricians perform the electrical installation with precision and attention to detail. We use high-quality materials such as copper wiring, tamper-resistant outlets, and energy-efficient fixtures suitable for ADU standards.


Installation includes running electrical conduit, panel upgrades or additions, and connecting circuits to provide power for essential systems like lighting, outlets, HVAC, and kitchen appliances. We ensure grounding and bonding meet safety standards to protect occupants and equipment.


We also integrate smart electrical systems when requested, enabling remote control and monitoring of lighting and appliances, which aligns with current ADU technology trends.


Final Testing and Inspection


After installation, we conduct comprehensive testing to verify all circuits function correctly and safely. This includes checking for proper grounding, voltage levels, and breaker operations.


We perform tests for potential issues such as shorts, overloads, or faulty connections. Any problems discovered are promptly resolved before final approval.


Once testing is complete, we coordinate with local inspectors to conduct mandatory

inspections for code compliance. Passing these inspections confirms your ADU electrical system is safe, reliable, and ready for use.

Frequently Asked Questions About Electrical System Installation


  • What is the cost of electrical installation for an ADU in Thousand Oaks?

    Electrical installation for ADUs typically ranges from $8,000-$20,000 depending on size and complexity. At Thousand Oaks Elite ADU Builder, we include panel upgrades, wiring, outlets, fixtures, and Southern California Edison connection fees in our transparent pricing. Costs vary based on service needs (100 vs 200 amp), distance from main panel, and special systems like EV charging.


  • Do I need special permits for ADU electrical systems in Thousand Oaks, CA?

    Yes, you need electrical permits from the Thousand Oaks Building and Safety Division. Our C-10 licensed contractors handle all permit applications, load calculations, and coordination with city inspectors to ensure compliance with Ventura County regulations and California Electrical Code requirements.

  • How long does electrical system installation take for an ADU?

    Electrical installation typically takes 5-10 working days across different construction phases. Rough electrical work requires 2-3 days during framing, finish work another 2-3 days after drywall, and panel upgrades add 1-2 days. We coordinate directly with Southern California Edison for timely service connections.

  • Can my existing electrical panel handle an ADU addition?

    Most residential panels need upgrading to accommodate an ADU. Standard homes have 100-150 amp service, while ADUs typically require 200 amps or more. Our master electricians perform NEC-standard load calculations to determine your needs, then implement appropriate panel upgrades, subpanels, or separate metering solutions.

  • What electrical code requirements must my ADU meet?

    Your ADU must comply with the California Electrical Code (2020 NEC) requirements: GFCI protection in wet areas, AFCI for bedrooms, outlets every 12 feet, dedicated appliance circuits, proper grounding, and hardwired smoke/CO detectors. Title 24 standards require LED lighting, occupancy sensors, and specific outdoor lighting configurations.
