Panel upgrade in San Diego
In San Diego the right question is not just how many amps but whether the house is historic, whether the street is on the undergrounding list, and what the job adds.
Is the house historic
Designated historic resources and houses in historic districts cannot use the City’s no-plan online route. They need a standalone permit with plans and historical review. Golden Hill and North Park have such blocks. Ask the electrician to check your address on the City’s map before quoting a date, and budget extra weeks, since plan-check time is not published. These houses are also often the ones with the oldest panels. The Zinsco and Federal Pacific page explains how to spot those brands. The general sequence is on the permit and inspection page.
Tell the electrician what the panel will carry
The SDG&E request depends on whether the project adds load. A swap that adds nothing is a different request from one that adds a charger, heat pump or ADU. Decide that before the electrician files, and ask which request was filed and what size the permit lists. Mismatched paperwork causes delays. About 32% of San Diego homes were built before 1970 and 52% before 1980, and the City does not publish service sizes by era, so each panel needs an on-site look. See the SDG&E programs guide for options and the 200-amp cost page for the typical SoCal range as of October 2026.
Undergrounding changes the timing
San Diego is moving overhead lines underground street by street. Each project needs an Underground Utility District created by the City Council, and the City picks streets by fire risk and community need. When your block’s turn comes, the utility connects your house to the new underground service at no cost only if the existing panel is up to code. An older panel that is not up to code can fail that check, so replacing it ahead of the trench crew can avoid a failed connection. The City says owners sign a Permit to Enter first.
Inspection day
Inspections are booked through the online permit account, and virtual inspections are offered. An adult needs to be on site to open the panel, because inspectors do not open live equipment. Ask the electrician which day the inspection and the utility visit will happen, and confirm the meter will be reconnected the same day. Local background is on the San Diego city page.

Questions people ask
Which San Diego homes cannot use the Simple Permit for a panel?
Designated historical resources and houses in historic districts cannot use the online no-plan permit. They submit a standalone permit with plans, and the City's historical review applies. Golden Hill and North Park have such blocks. Ask the electrician to check the City's map of historic resources before quoting a date.
Should I replace my panel before my street is undergrounded?
It can help if the panel is old. The utility connects your house to the new underground line at no cost only when the existing panel is up to code. A separate contractor works on panels during the trench phase, and owners sign a Permit to Enter first. Replacing it early avoids a failed check.
Does a San Diego panel upgrade need a separate SDG&E request?
Yes. The electrician files the City permit and an SDG&E request, and the right request depends on whether the job adds load. A swap with no added load is simpler than one that adds a charger or heat pump. Ask which request was filed and what size each lists, so the paperwork matches.
How do I schedule the panel inspection in San Diego?
Inspections are booked through the same online permit account, and virtual inspections are offered. An adult must be present to open the panel, since inspectors do not open energized equipment. Ask your electrician to book it for a day you are home, and to coordinate the utility reconnect.
