Get matched with a licensed proElectrical work in Altadena ranges from a single circuit addition to a full service upgrade, and the licence scope is the same either way. What changes is whether the panel has capacity, whether the wiring is copper or aluminum, and whether anyone has added circuits without permits over the years.
Older housing stock often has undersized panels and ungrounded branches. A contractor who quotes fixture swaps without opening the panel is pricing the visible work only. Ask what they found on the last three service upgrades in homes built before 1970 — the answer tells you whether they plan for surprises. Request a written scope that names the panel, circuits and inspection milestones.
Arc-fault and GFCI requirements expanded in recent code cycles. A panel upgrade is often the moment to bring branch circuits into compliance, not only to add capacity for new loads.
Class C-10 (Electrical) is the classification CSLB issues for installing, maintaining and connecting electrical wires, fixtures and equipment. It is a specialty licence — not general building — and the person signing the contract for wire work should hold it.
Every electrician on this page holds an active Class C-10 (Electrical) licence recorded at a Altadena address. The licence number is on the card and links to the CSLB record, which you can check in seconds for status and expiry.
A licence confirms permission to do the work, not whether someone labels circuits clearly or leaves the panel neat enough to service later. Ask to see a recently completed panel upgrade and whether the permit card was posted during rough-in. Those details predict how the job will go on your house.

Yes for most panel upgrades, new circuits and service changes. LA County Building and Safety issues electrical permits and schedules inspections. An unpermitted service change can surface during a sale or insurance review.
A Class B contractor may perform electrical work within a larger project, but specialty electrical firms usually hold Class C-10 (Electrical). Verify the entity on the contract holds the classification for the work being billed.
Home improvement contracts cap the down payment at 10 percent of the price or 1,000 dollars, whichever is less. Larger electrical projects should tie payments to inspection milestones rather than calendar dates.
