Electrical Panel Upgrade in Laguna Hills, CA
Wilson Electric performs residential and commercial panel upgrades throughout Laguna Hills. Developed primarily in the 1970s and 1980s, Laguna Hills has a significant housing stock that is now 40–50 years old — and a large proportion of homes are still on original 100-amp electrical panels that were not designed for today's electrical demands. We pull all permits through the City of Laguna Hills Building Division, coordinate the SCE utility disconnect, install the new panel, and pass the city inspection. You talk directly with Taylor Wilson — a Certified Journeyman Electrician with a California C10 License (#1108912) — on every job.
How Much Does a Panel Upgrade Cost in Laguna Hills?
Most residential main service panel upgrades in Laguna Hills run between $3,500 and $6,000. The range depends on the size of the new panel (100A, 200A, or 400A), permit fees through the City of Laguna Hills, and whether additional work is required — such as replacing the meter base or upgrading grounding.

Why Laguna Hills Homes Commonly Need Panel Upgrades
Laguna Hills was built out primarily in the 1970s and 1980s, which places much of its housing stock squarely in the age range where panel upgrades become necessary. Common scenarios in Laguna Hills include:
Original 100-amp panels — Many single-family homes in Laguna Hills left the factory with 100-amp main panels. At the time, this was adequate. Today, with EV chargers, central AC, home offices, and smart home systems, it frequently is not.
Federal Pacific and Zinsco panels — These panels were installed in a number of Laguna Hills homes during the original build-out and are documented fire hazards. Insurance companies frequently flag or refuse to cover homes with these panels. If you have one, replacement is not optional.
ADU additions — Laguna Hills homeowners are increasingly adding ADUs to their properties. An ADU almost always requires a panel upgrade or subpanel addition to support the added electrical load.
EV charger additions — A Level 2 EV charger requires a dedicated 240V, 50A circuit. Most original Laguna Hills panels cannot add this circuit without an upgrade.
