List the loads in the new unit
Start with equipment that can affect the electrical scope. List the cooking appliances, water heater, heating and cooling equipment, laundry and any charger you plan to add. Include model information where it is available and flag selections that are still open. If you are converting a garage, identify the circuits and equipment you want to retain.
Review the service before choosing equipment
Share available electrical drawings, a readable panel schedule and photographs of equipment labels only when you can take them safely without opening a cover. Your electrician can evaluate the existing load and proposed equipment, including whether the property needs additional capacity. A free breaker position alone does not establish that the existing service has enough capacity.
Plan the wiring route with the site plan
Show the existing service and the proposed unit on the site plan. A detached unit may need a route across the property. An attached or converted space may require access through finished areas. Review the route with the builder before concrete, walls or ceilings close off access. Ask who will handle trenching, patching and coordination with other trades.
Check with the local department and utility
California HCD’s handbook explains the statewide ADU framework. LADBS provides a standard plan program for projects in the City of Los Angeles. Confirm which building department and electric utility serve your property before relying on local guidance. If a service or meter change is under consideration, raise it with the utility early.
What to bring to the first discussion
Bring the floor plan and site plan, the equipment list, existing service information, and any utility or permit correspondence. Ask which assumptions affect the estimate, what utility or permit steps are still open, and when the electrical work needs to be coordinated with framing or finishes.
