San Gabriel Valley & Gateway
San Marino utility bills in 2026
That's about $7,327 a year for electricity, water, gas, sewer and trash: roughly $694 in a summer month and $527 in winter. Electricity is the biggest piece at $345 a month. The same house in nearby South Pasadena comes out about $25 a month less.
Rough estimate. At least one service (usually water, sewer or trash) is still an estimate that hasn’t been checked against local rates. Treat the total as a rough guide.

How these estimates work
BillSwap models one household's monthly use (kWh of electricity, gallons of water, therms of gas) from its size, occupants and climate, then runs it through each utility's published rate schedule: tiers, fixed monthly charges and, where known, local utility taxes. Sewer and trash use each city's charge. Nothing here comes from a real bill, so your actual bill will differ with your habits, appliances and exact address. Describe your own household for a closer estimate.
