San Bruno housing runs from Huntington Park and Mills Park homes built around World War II to 1960s Portola Highlands houses and downtown condos. Each has its own wiring issues.
Ungrounded circuits, two-prong outlets and too few kitchen circuits are common in 1940s and 1950s homes.
Additions on Mills Park lots often tie into the original circuits. HAXX checks capacity and adds dedicated circuits where needed.
When work requires a permit, HAXX applies through SB Permits and meets the city inspector.

“The technician from Haxx immediately pointed out multiple violations of the National Electrical Code and explained that the wiring was overheating and could potentially become a fire hazard. They offered to redo the installation the correct way, pulled the proper permit, and installed the EV charger safely and professionally. The city inspection passed without any issues.”
“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!”
