Planning EV charging or an ADU in LA or OC? Check panel load before permits

On Los Angeles and Orange County projects, electrical planning often gets left until after the exciting decisions: the EV charger is picked, the ADU layout is drawn, or the kitchen appliance package is ordered. The problem is that many older homes are still working from a 100 amp service, crowded breaker spaces, mixed past wiring, or a panel location that makes new dedicated circuits harder than expected.

Before permits or equipment orders, confirm the main service size, available breaker spaces, existing large loads, planned EV charger amperage, ADU appliance loads, bathroom and kitchen dedicated circuits, and whether a subpanel or full panel upgrade is the cleaner path. If the home also needs water damage repair, estate updates, or a remodel, include those circuits in one load review instead of solving them one at a time.

The practical sequence is panel photos, site walk, load calculation, permit scope, utility coordination if needed, panel or subpanel work, rough circuits, inspection, then charger, ADU, or remodel finish installation. Energy Star Builders helps LA and OC homeowners coordinate panel upgrades, EV charging, ADU electrical, and remodel circuits before inspections stall the job.
