Electrical Work for DADUs, ADUs, and Backyard Cottages
A DADU or ADU needs an electrical system that is safe, reliable, efficient, and properly matched to how the space will be used. Whether you are building a new detached unit, converting an existing structure, or upgrading a small secondary living space, the electrical plan matters from the beginning.
Benchmark Home Services provides residential electrical support for homeowners who need wiring, circuits, lighting, panels, subpanels, appliance connections, EV charger preparation, and related electrical upgrades for DADU and ADU projects.
Planning tip: DADU and ADU electrical needs can depend on layout, load requirements, appliance choices, utility service capacity, permitting, and inspection requirements. Early electrical planning can help avoid delays and costly changes later.

Frequently Asked Questions
Do DADUs and ADUs need separate electrical panels?
Not always. Some projects may use a subpanel, while others may require panel upgrades or additional electrical planning depending on load needs, existing service capacity, appliance choices, and project requirements.
Can you help with electrical planning before construction starts?
Yes. Early planning is helpful for DADU and ADU projects because appliance loads, lighting, heating equipment, EV charger needs, and panel capacity can affect the electrical scope.
Do you install EV charger circuits for DADU or ADU projects?
Yes. We can help with EV charger circuit planning and installation as part of a DADU, ADU, garage, or residential electrical upgrade.
Do you handle small ADU electrical repairs too?
Yes. We can help with troubleshooting, circuit issues, lighting problems, outlet and switch repairs, and electrical updates for existing ADUs and DADUs.
