Engineering Excellence for ADU Electrical Contractor
Accessory Dwelling Units (ADUs), garage conversions, and backyard guest homes are booming across Los Angeles. Powering an ADU requires specialized electrical engineering to calculate demand, route underground feeders, and ensure full California Title 24 compliance. LAD ELECTRIC LLC is a premier ADU Electrical Contractor in Los Angeles, CA.
Our licensed California C-10 certified journeyman electricians provide turnkey electrical services from underground trenching and conduit installation to subpanel mounting, rough-in circuit wiring, Title 24 lighting controls, mini-split HVAC circuits, kitchen appliances, and dedicated EV charging.
We help homeowners decide between sub-metering from the primary home panel or installing a separate utility multi-meter center so ADU tenants receive their own direct electric bills.
With hundreds of completed ADU electrical installations across Los Angeles County, we guarantee smooth LADBS inspections and on-time project completion.
Critical Safety Notice & Los Angeles Context
An ADU adds substantial electrical load (HVAC, water heater, kitchen range, laundry) to a residential property. Inadequate service sizing or improper grounding can cause frequent main breaker blackouts for both the main house and the ADU.
