Subpanel Installation cost in Point Loma, CA.
A sub-panel adds circuit capacity to a garage, ADU, shop, or pool equipment pad without rerunning the entire main service. Cost is driven mostly by feeder distance, conduit run, and the amperage the new panel needs to carry..
What does subpanel installation cost in Point Loma?
In Point Loma, subpanel installation runs $1,700–$3,100, with a straightforward job landing near $2,200. Point Loma occupies the peninsula between the bay and the ocean, and its housing spans nearly the whole 20th century: 1910s and 1920s cottages in the older village and La Playa, mid-century ranch and custom homes along Catalina Boulevard and Chatsworth Boulevard, and newer custom builds toward Sunset Cliffs. That housing mix is why local pricing sits where it does, not at a flat countywide number. Every quote is flat-rate before work starts, with no trip fee to Point Loma.
Why subpanel installation costs what it does in Point Loma
A garage or ADU sub-panel near the water needs the same corrosion-rated enclosure and hardware as a full panel upgrade, which pushes the range above the county baseline. Point Loma and OB lots are often narrow, so the feeder run from the main panel to a rear ADU or garage can be longer than a typical inland layout.
- Corrosion-resistant enclosure and breakers for salt-air exposure near the water
- Narrow beach-community lots sometimes mean a longer feeder run to a rear ADU or garage
- Conduit often needs to be sealed and rated for exterior salt-air exposure
- Permit through the City of San Diego or Coronado depending on the property

Point Loma subpanel installation cost questions
Why does a coastal ADU sub-panel cost more than the same job inland?
The enclosure and breakers need to be corrosion-rated for salt air, and narrow beach lots often mean a longer feeder run from the main panel to the ADU or garage.
Does adding a sub-panel for an ADU near the coast need a special permit?
It goes through the same city electrical permit as any sub-panel, though ADU projects near the coast sometimes trigger an additional planning review depending on the lot.
My older Point Loma cottage still has knob-and-tube. Do I need to rewire?
If it is active, most California insurance carriers will not renew, which pushes most La Playa and Roseville cottage owners toward a full or staged rewire. We work carefully around original finishes, remediate section by section, and provide written documentation for your carrier. Full rewire on a cottage here runs $12,000 to $23,000 depending on access and restoration.
Can you install EV and solar together on my Point Loma home?
Yes. We coordinate a service upgrade sized for EV, solar interconnection, and future load in one project, and on larger custom homes we add a smart panel for circuit-level monitoring. The combined EV-plus-service project runs $4,000 to $5,900, and a full EV-plus-solar-plus-service coordination runs higher depending on system size and smart-panel options.
