Moving anywhere inside the city of San Diego means SDG&E for both electricity and gas. California doesn't let you shop retail electric suppliers, so whoever holds the wires at your address is who you get — and here that's SDG&E at every sampled address. Water and sewer work differently: at nearly all sampled addresses, both are run by the City of San Diego's own public utilities department. So SDG&E supplies your energy, and the city itself handles what comes through the pipes.
San Diego sprawls north and east across dry mesas and steep canyons, and almost none of its water falls locally — most is imported and moved through the city-run system, which is why the utility department here looms so large. On the power side, many neighborhoods are now auto-enrolled in San Diego Community Power for generation, but that only changes where your power is generated. SDG&E still owns the poles, maintains the lines, and shows up when the lights go out.

Based on 12 sampled San Diego addresses spanning ZIP codes 92101, 92104, 92107, 92109, 92111, 92114, 92115, 92119, 92123, 92126, 92128, 92154 (2026-07-20). Yours may differ — the San Diego lookup is the tiebreaker.
SDG&E covers electricity and gas across the whole region, so that part rarely changes. Water and sewer are what shift at the edges: cross into Coronado and a few addresses fall to California American Water instead of the city, and unincorporated county pockets can differ again.

Whether you're landing in North Park, Point Loma, or a new build out in Otay Mesa, run this quick checklist before your first night in San Diego.
At every one of the San Diego addresses we sampled, SDG&E was the electric utility. The exact San Diego provider depends on the address.
Generally no — San Diego electric territory is fixed by address: the utility holding your San Diego block is your utility, and at every one of sampled San Diego addresses that was SDG&E — San Diego is a one-signup town.
At nearly all of the San Diego addresses we sampled, City of San Diego was the water provider — sewer included. Other districts take over around San Diego's edges, so check your block.
No — at every one of the sampled San Diego addresses, SDG&E was the gas utility, but plenty of San Diego homes are all-electric and never open this account.
No. California has no retail electric choice, so the utility that holds your address is simply the one you use — and across San Diego, that's SDG&E at every sampled address, for both electricity and gas. Your neighborhood may be auto-enrolled in San Diego Community Power for the generation portion, but SDG&E still runs the wires, handles delivery, and responds to outages no matter what.
At nearly all sampled addresses, water and sewer are both run by the City of San Diego through its own public utilities department — city-run service. A small number of addresses, mainly around Coronado, are served by California American Water instead. Because that boundary isn't obvious from the street, it's worth confirming your exact address with the lookup before you assume which one serves you.
For most San Diego homes, there are two main providers to line up: SDG&E for both electricity and gas, and the City of San Diego for water and sewer. That's fewer separate companies than movers deal with in a lot of other markets. If your new place sits near Coronado, run the lookup first — a small share of addresses there get water and sewer from California American Water rather than the city.
