Upgrading an electrical panel in Pasadena
A Pasadena panel upgrade is planned around what the house will add next: a charger, an electric water heater, air conditioning. The city-run utility and the permit queue both shape the schedule.
Size the panel for the next five years
A panel is sized from a load calculation, not from the old panel’s rating. In Pasadena that calculation should list the air conditioner, since zone 9 summers are long, and anything electric you plan to add: a charger, a heat pump, an electric water heater. PWP, the city’s own utility, offers a panel rebate with design conditions of its own, so ask the electrician to read them first. Settle that before the panel is sized. The electrification order of operations guide helps with sequencing.
What an old house can hide
The median Pasadena home was built in 1961. About 49% were built before 1960 and 36% before 1950. Houses from before 1940 may have fuse panels or knob-and-tube wiring inside the walls. A 200 amp upgrade usually reveals it. Ask for the finding in writing, with a photo, and ask whether any circuits need work before the new panel goes in.
A standard swap is a typical SoCal range of $2,500 to $4,500. A meter move or new service run brings $5,500 to $10,000, as the cost page shows. A new service also needs a surge protective device, so check that it is in the quote.
Landmark districts and the inspection queue
In Bungalow Heaven, a landmark district, the panel’s location matters. A new meter panel on a street-facing wall may need design review first, so ask early and consider a side wall. After the January 2025 Eaton Fire the division also said inspections may be delayed. The permit and inspection page lists what the inspector checks. Book as soon as the electrician finishes, since the power-off window depends on it.
Because Pasadena has its own utility and its own permit center, ask any bidder how many jobs they have done in the city and which steps they handle. Get the answer in writing, along with who requests any utility work and who books the inspection. A written scope that names these steps prevents the common gap where each side assumes the other is handling it.
If the charger is first
If the charger is the main goal and the panel has room, you may not need the swap. The Pasadena charger page covers the permit, rate and landmark questions, and the city utility rebate guide shows what PWP offers.
Utility and meter work
PWP, not SCE, sets and reconnects the meter, so service upgrade requests go to PWP. PWP's panel rebate requires a City of Pasadena electrical permit and a final approval before the claim (apply within 180 days of final permit approval).

Questions people ask
Should I decide on the water heater before sizing the panel?
Yes. A panel is sized from a load calculation, and an electric water heater, a charger and an air conditioner each add to it. The city utility's panel rebate has its own design conditions, so ask your electrician to read them and design the panel to fit before the permit is filed, not after the work is done.
What if the electrician finds knob-and-tube wiring?
The panel can usually still be swapped, but the wiring is a separate decision. Under the code, knob-and-tube may not stay in spaces where insulation covers the wires, and the rules vary by city. Ask the electrician to note which circuits are affected and price them as a separate line.
Does a delayed inspection hold up anything after the swap?
Yes. The city said after the Eaton Fire that inspection delays may occur. The new panel is not approved until it passes, and any claim that needs final permit approval waits too. Book the inspection online as soon as the work is done and plan the shutoff window with some slack.
Will a new meter panel on my Bungalow Heaven house need review?
It may. Bungalow Heaven is a city landmark district, and a meter panel or conduit on a street-visible wall may need design review before the electrical permit. Ask the city early, and ask the electrician whether the panel can mount on a side wall or inside the garage.
