Zinsco and Federal Pacific panel replacement cost

Basis: estimate. The $2,500 to $5,500 range is a desk estimate for a typical SoCal job as of October 2026. It starts at the same floor as a standard panel upgrade and leaves room at the top for repair work. A national cost site says replacement costs for Federal Pacific and Zinsco panels are in line with overall averages. It gives no separate figure.

The price is a normal swap plus a surprise budget

Replacing a Zinsco or Federal Pacific (FPE) panel is the same job as any panel swap. The old panel comes out and a new one goes in. The extra cost comes from what the old panel tells the electrician once it is open. Heat damage, loose connections and mixed-up wire are possible in panels of this age. The national site gives a way to price repairs: $6 to $8 per linear foot of wire.

So the honest answer is a spread. A clean swap lands near the low end. A panel with burned parts and several damaged circuits lands near the high end.

Why the age of the house matters

FPE panels were common from about 1950 to 1980 and Zinsco in the 1970s, per the national cost site. Houses with these panels also tend to have other aging equipment. If you are replacing the panel, ask the electrician to look at:

• The meter socket and service wires
• Grounding at the panel
• Old wiring types. See aluminum wiring and knob-and-tube
• Whether 200 amps makes sense at the same time. See the 200-amp cost

Where these panels turn up in SoCal

The cost site’s dates (FPE about 1950 to 1980, Zinsco in the 1970s) point at homes from the postwar and tract-house years. Census figures show where that stock is concentrated. In South Gate the median home was built in 1952, and 64 percent of homes date from before 1960. In Whittier the median is 1956 and 67 percent were built before 1960. In Lakewood the median is 1957 and 82 percent were built before 1970. In those three cities, a panel from the 1950s through the 1970s is a realistic find, though many homes have had the panel changed since. Newer areas such as Palmdale, where the median home dates to 1989, are unlikely to have either brand. The build year is only a hint: the brand name on the panel label is the answer.

Decision: replace now or wait

This is not just a cost question. A homebuyer’s inspector may flag one of these panels, and an insurer may ask about it. The home-sale inspection guide covers what to expect. The service page covers the safety reasons electricians give for replacing them. The panel reading guide helps you identify the brand from a photo.

What an electrician checks before quoting

A good quote starts with a look inside the panel and at the meter. The electrician notes the brand label, the number of circuits, and any signs of heat such as dark marks or melted insulation. They also check the grounding and the main service wires. A separate electrical inspection can run $125 to $250 in national data, sometimes credited back if you hire that electrician. A quote written from a photo alone is a rough number. Ask for the final price after the visit, and have it say what happens to the price if the panel opens badly.

Permits and rebates

A panel replacement needs a permit and an inspection like any panel job. Fees and offices differ by city, so see the Los Angeles, Long Beach and Santa Ana pages, or the county hubs. Pasadena Water and Power lists a $1,000 rebate for an electric panel upgrade, plus $500 more for customers enrolled in its income-qualified bill assistance. It is for PWP residential customers, and the application has to be filed within 180 days of final permit approval. Confirm the terms on the PWP rebate page before you sign a contract. Burbank, Glendale and Anaheim also add smaller panel payments to a charger rebate; the rebate finder lists them.

How to compare quotes

1. Ask each electrician to say in writing what happens if damage is found.
2. Ask for the per-foot or per-circuit rate for repairs before work starts.
3. Confirm the new panel size, brand and number of spaces.
4. Confirm the permit and inspection are in the price.
5. Ask for photos of the old panel’s interior if repairs were needed.

What is not included

Drywall or stucco repair, trenching, a new meter base if the utility requires one, and rewiring of the house beyond the circuits touched. The estimate also does not include any insurance or home-sale paperwork. A separate inspection may cost $125 to $250 nationally, sometimes credited if you hire that electrician.
