Customized Electrical Solutions

Personalized Planning And Design

We begin every project with a thorough consultation to understand your electrical requirements. Our experienced technicians assess your ADU's layout, intended usage, and your specific power needs before creating a customized plan.


Your unique living patterns and preferences guide our design process. Need extra outlets in your home office? Planning to install high-powered appliances? We account for these details in the planning stage.


We provide detailed electrical plans that comply with all local codes and regulations. These plans show the precise locations of outlets, switches, lighting fixtures, and appliance connections.


Our team can adjust plans as your project evolves. We understand that flexibility is important when building an ADU that truly works for you.

Energy-Efficient Installations

Our electricians install LED lighting systems that consume up to 75% less energy than traditional bulbs while lasting significantly longer. These systems provide excellent illumination quality with minimal power usage.


We offer upgraded electrical panels that distribute power more efficiently throughout your ADU. These modern panels prevent energy waste and reduce the risk of electrical issues.



Timer switches and motion sensors can be installed to automatically control lighting in less frequently used areas. This small addition prevents unnecessary electricity consumption.


Energy monitoring systems allow you to track your power usage in real-time through smartphone apps. This visibility helps you identify opportunities for further energy savings.

Smart Home Integration Options

We install programmable thermostats that learn your schedule and adjust temperatures automatically. This technology can reduce heating and cooling costs by up to 15% annually.



Smart lighting systems allow you to control brightness, color, and scheduling from your phone. You can create custom lighting scenes for different activities or times of day.


Voice-activated controls can be integrated with your electrical systems, allowing hands-free operation of lights, appliances, and other devices. This feature is particularly valuable for accessibility.


Security-focused smart home features like automated exterior lighting and doorbell cameras provide peace of mind. These systems can be monitored remotely through your smartphone.

Upgrades And Additional Services

Panel And Wiring Upgrades

We specialize in electrical panel upgrades to support your ADU's growing power needs. Many older properties have outdated 100-amp panels that can't handle modern appliances and technologies. Our team can install 200-amp panels or larger depending on your specific requirements.


Wire upgrades are essential for safety and efficiency. We replace old aluminum or knob-and-tube wiring with modern copper wiring that meets current electrical codes. This reduces fire hazards and prevents power fluctuations.



Smart home integration is another popular upgrade. We can install smart switches, programmable thermostats, and automated lighting systems that you can control remotely. These technologies not only add convenience but can reduce energy costs by up to 15%.

Electrical Maintenance Services

Regular maintenance prevents costly emergencies and extends the life of your electrical system. Our maintenance packages include thorough inspections of panels, outlets, switches, and fixtures to identify potential issues before they become problems.


Emergency services are available 24/7 for unexpected electrical issues. Our technicians arrive promptly with fully-stocked service vehicles to address problems quickly and efficiently.



Preventative maintenance can save you significant money in the long run. Catching small problems early prevents system failures and property damage. We provide detailed reports after each maintenance visit so you understand your system's condition.
