Home Rewiring
Lots of North Hollywood homes still run on wiring from the post-war building boom. Here's how to tell whether yours is still safe, or ready for an upgrade.

Old wiring in North Hollywood homes isn't automatically unsafe, but wiring from the 1940s–1960s often lacks grounding, has worn insulation, and was never sized for today's electrical loads, so it should be inspected by a licensed electrician. Warning signs include two-prong outlets, warm switch plates, flickering lights, burning smells, and breakers or fuses that trip often. Many San Fernando Valley homes were built during the post-war boom, so these issues are common across North Hollywood.

Our guide to common electrical problems explains what each of these symptoms usually means.
North Hollywood summers regularly top 95°F, and fall can still bring highs in the 80s°F during Santa Ana conditions. Air conditioners running for hours put a steady load on circuits, and older insulation breaks down faster when conductors run hot. That's why so many older-wiring calls come in during the hot months.
It depends on what an inspection finds. Some homes only need a panel upgrade, a few new dedicated circuits, and GFCI protection on ungrounded outlets. Others with deteriorated insulation throughout are better off with a full rewire. Start with an electrical safety inspection. If the wiring is past saving, our home rewiring guide covers what to expect.
North Hollywood is part of the City of Los Angeles, so electrical permits go through the Los Angeles Department of Building and Safety (LADBS). Electric service is provided by LADWP. A licensed contractor pulls the permit and schedules the inspection for you.

I had a great experience with this electrical service. The team showed up on time, worked efficiently, and finished the job faster than I expected while still doing everything the right way. The price was very fair compared to other quotes I received, which made the whole experience even better because the quality of work was still top-notch. I also want to give a shout out to Barrett for being pr…

Barrett came out and gave me a good price on the work. They replaced my electrical panel and installed a disconnect for my AC unit. Then the next day, had a guy come out to patch up the wall and paint when the stucco dried. He also had the number of an AC technician for me to call to move a thermostat wire. Overall, great work and very communicative throughout the process.
