Electrical Panel Upgrade: When You Need One and What It Costs

An electrical panel upgrade is one of the more expensive projects a homeowner can face, but it's also one of the most clearly necessary when it's actually needed. The trick is knowing when it's needed — and not paying for one when it isn't.

This guide walks through what a panel upgrade actually is, when you genuinely need one, and what the realistic costs and timelines look like in Los Angeles.

What a panel upgrade actually is

A panel upgrade involves:

• Removing the existing main panel and meter (sometimes the meter too)
• Installing a new, larger-capacity panel (commonly 200 amps)
• Reconnecting all existing circuits to the new panel
• Coordination with the utility to disconnect and reconnect the service entrance cable
• City permit and inspection

It's not just "swapping a breaker box." It's a regulated piece of work that requires a permit, a temporary power shutoff (usually 4–8 hours), and inspection.

When you actually need one

Your home has less than 100-amp service

Many older LA homes have 60-amp or 100-amp service. Modern living (central AC, electric dryer, EV charger, hot tub, multiple kitchen circuits) typically needs 200 amps. If your home has 60-amp service, you almost certainly need an upgrade before any major appliance addition.

You're installing a major new load

A Level 2 EV charger (the kind people install at home) typically needs a dedicated 50-amp or 60-amp circuit. That alone can require a service upgrade on older homes.

Other major loads that can trigger an upgrade:

• Hot tub or spa
• Tankless water heater
• Solar + battery backup
• Central AC replacing a window unit
• ADU (accessory dwelling unit) on the property

Your panel is full or nearly full

Panels have a fixed number of breaker slots. If yours has no open slots, you have three options: install tandem breakers (limited by panel design), add a sub-panel, or replace the main panel. In some cases, replacing the main panel is the cleanest option.

Your panel is a known safety issue

If your panel is Federal Pacific (Stab-Lok), Zinsco, or Sylvania, replacement is recommended regardless of capacity — see our earlier post on those brands specifically.

Your insurance carrier requires it

Some carriers won't renew or write new policies on homes with outdated or recalled panels. The carrier's timeline isn't a recommendation — it's a requirement for coverage.

When you don't need one

The flip side of an honest guide:

• You bought a new dishwasher → you don't need a panel upgrade, just a circuit
• Your panel is "old" but functional → if it's a modern panel from a reputable brand (Square D, Eaton, Siemens, GE) and has been maintained, age alone is not a reason to replace
• Your electrician says you should "just in case" → push back and ask what specifically is driving the recommendation

Panel upgrades are valuable when they're needed. They are not a routine preventive measure.

What it costs in Los Angeles

Approximate 2026 figures (LA market, including permit and inspection):

• 100-amp → 200-amp upgrade: $2,500–$6,500
• Like-for-like swap (no capacity increase): $1,800–$3,500
• Service entrance + panel + meter base: $4,000–$9,000+

Variables that move the price:

• Panel location (interior vs. exterior, garage vs. side of house)
• Service entrance condition
• Need for trenching or new conduit runs
• Whether the utility needs to upgrade the drop or the meter
• Permit fees by city (Santa Monica, Beverly Hills, and parts of LA have higher permit fees than others)

How long it takes

A typical residential panel upgrade takes 4–8 hours of actual work, but the total project timeline is 1–3 weeks because of:

• Permit application (1–2 weeks)
• Utility coordination (varies; sometimes same-day)
• The actual install day
• City inspection (usually next business day after install)

You will be without power on the install day. Plan accordingly — keep fridge closed, charge devices ahead of time, make arrangements if you work from home.

What to ask your electrician

Before scheduling a panel upgrade, ask the electrician:

1. Why are you recommending this specific upgrade? What problem does it solve? If the answer is vague, push back. 2. What size panel are we installing, and why? Usually the answer is 200 amps, but it depends on your actual load. 3. Who pulls the permit? It should be the electrician or their company, not you. 4. Is the work inspected by the city? Yes. If the answer is anything else, walk away. 5. What's the warranty? Most reputable electricians offer 1–3 years on labor, longer on materials.
