How Long Does an Electrical Panel Upgrade Take in LA?

A standard residential panel upgrade is usually a one-day job - but the full process from quote to final inspection spans about one to three weeks. Here's the realistic breakdown for Los Angeles homeowners.

Assessment & Quote (1-2 days)

We inspect your panel, meter base, and service drop, then provide a fixed quote. No obligation.

Permit (3-10 days)

LA city or county issues an electrical permit. We handle the submission; timeline varies by jurisdiction.

Installation Day (4-8 hours)

Power is shut off, the old panel removed, new 200-amp panel installed, circuits re-terminated and labeled.

Inspection & Power On (same or next day)

A city/LADWP inspector signs off; we restore permanent power and walk you through the new panel.

What Slows It Down

Factors That Extend the Timeline

📜

Meter Base Issues

If the meter socket or service mast is damaged or undersized, it must be replaced - adding a few days.

🧾

Knob-and-Tube

Homes with old wiring may need partial rewiring before a panel can be safely energized.

Permit Backlog

Some LA jurisdictions take longer to issue permits during peak season. We flag this up front.

Questions

Panel Upgrade Timeline FAQ

Can a panel upgrade really be done in one day? ▾

Yes. The physical install is typically 4-8 hours. The longer part is the permit and inspection, which can add 1-2 weeks around the install day.

How long will I be without power? ▾

Usually 4-8 hours on install day. We schedule early and restore power the same day in nearly all cases.

Do I need to be home during the upgrade? ▾

Yes for the install day so we can access the panel and breaker areas, and for the final walkthrough.

Why does the permit take so long? ▾

Each LA jurisdiction processes permits at its own pace. We submit immediately after you approve the quote to minimize the wait.

Can you upgrade the panel and add an EV circuit the same day? ▾

Often yes. If the new panel has capacity, we install the EV charger circuit during the same visit.
