San Mateo Kitchen Rules
Electric-ready rules: San Mateo repealed its all-electric requirement in February 2025. What remains: a 240V/50A circuit at the range when a kitchen is altered, a 240V/30A circuit when laundry is altered, and heat-pump-ready wiring where a gas furnace is installed.
That means a gas range can stay, but altering the kitchen requires a 240V/50A circuit ready for a future electric range. We check panel capacity first.
