Electrical Panel Upgrade Cost in Los Angeles County: 2026 Guide

What Does a Panel Upgrade Cost in LA County?

Most residential electrical panel upgrades in Los Angeles County cost between $2,000 and $4,500 in 2026. The final price depends on the home's existing service, the new panel size, utility coordination, permit requirements, and whether the electrician must repair or replace wiring.

What Affects the Price?

Service size: A standard 200-amp panel works for many modern homes. A larger home, multiple air-conditioning systems, an EV charger, pool equipment, or electric appliances may require a load calculation and a 400-amp service.

Panel location: A panel in an accessible location is usually simpler to replace. Relocating a panel, upgrading the meter base, or trenching new service conductors adds labor and materials.

Permits and utility coordination: California panel upgrades require permits and inspection. Your electrician may need to coordinate a temporary power shutoff with LADWP, SCE, or another local utility.

Additional circuits: A panel upgrade is a good time to add dedicated circuits for an EV charger, heat pump, kitchen appliances, or an ADU.

Signs You May Need an Upgrade

• Breakers trip frequently or lights dim when appliances start
• The panel is warm, rusted, damaged, or shows scorch marks
• Your home still has a fuse box or an outdated electrical panel
• You cannot add circuits for planned appliances
• You are planning an EV charger, solar, remodel, or addition

Do not choose an electrician based on a low price alone. Ask whether the quote includes the permit, utility coordination, load calculation, inspection, and cleanup.
