SAN FRANCISCO DETAILSPanel upgrades in
Panel upgrades in
San Francisco.
About 44 percent of San Francisco homes were built before 1940. Many still have small services and older panels that were never sized for electric heat or EV charging.
01
Load calculation first
HAXX calculates your load before recommending an upgrade. Sometimes a smart panel or load management avoids a larger service.
02
Older wiring
Pre-war homes can have knob-and-tube or ungrounded circuits. HAXX notes what it finds so you can plan repairs along with the panel.
03
Permits and PG&E
HAXX files the electrical permit with DBI and coordinates any service upgrade and reconnection with PG&E, which delivers power in the city.

★★★★★
“Recently, my dishwasher stopped working, and they discovered it was actually an outlet issue. Not only did they diagnose it quickly, but they also fixed the outlet—saving me from calling an electrician. Reliable, professional, and skilled at handling both appliances and electrical issues.”
★★★★★
“I purchased a couple of ceiling fans and was reluctant due to how old my house was with old wiring so I wanted someone professional and trustworthy. They have been both!”
★★★★★
“Prompt and professional - they helped run a new thermostat wire through a wall and crawl space.”

GOOD TO KNOW
Electrical Panel Upgrade in San Francisco: questions, answered.
How do I know if my panel needs an upgrade?
Frequent breaker trips, no open slots, an obsolete panel brand or plans for a heat pump or EV charger are common signs. HAXX confirms with a load calculation.
Who handles the permit in San Francisco?
HAXX, as a licensed contractor registered with the city, applies through DBI's online electrical permit system and schedules the inspection.
Do I need 200 amps?
Not always. A load calculation shows whether your current service can carry the new appliances, sometimes with load management. HAXX recommends an upgrade only when the numbers require it.
How long does a panel upgrade take?
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
