Whole-House Rewiring in Los Angeles: Cost & What to Expect

Older homes are everywhere in Los Angeles — and many still run on wiring that was never designed for modern electrical demand. If your lights flicker, breakers trip often, or you’ve found old cloth-insulated or knob-and-tube wiring, you may be looking at a partial or whole-house rewiring. Here’s what that involves and what drives the cost.

Signs Your Home May Need Rewiring

• Frequently tripping breakers or blown fuses
• Lights that flicker or dim when appliances run
• Discolored, warm, or sparking outlets and switches
• A burning smell with no obvious source
• Two-prong (ungrounded) outlets throughout the home
• Knob-and-tube or cloth-insulated wiring (common in pre-1960s LA homes)
• An old fuse box instead of a breaker panel

If you’re seeing several of these, have a licensed electrician evaluate the system before it becomes a safety issue.

What Affects the Cost of Rewiring

There’s no single price — every home is different. The biggest factors are:

1. Size of the home and the number of rooms, outlets, and circuits.
2. Accessibility — open walls, attics, and crawl spaces make the job faster; finished plaster walls take more labor.
3. Whether the panel needs upgrading at the same time (older homes often do).
4. Permits and inspection, which are required for this kind of work in Los Angeles.
5. Any code upgrades triggered along the way, such as grounding, GFCI/AFCI protection, and smoke/CO detectors.

A licensed electrician will assess these in person and give you a clear, itemized estimate — which is far more reliable than any online "average."

The Rewiring Process

1. Assessment & quote — we inspect the existing wiring, panel, and layout.
2. Permitting — we pull the required permits with the city.
3. Rough-in — old wiring is removed or abandoned safely and new wiring is run.
4. Panel & devices — the panel is upgraded if needed and new outlets, switches, and fixtures are connected.
5. Inspection & finish — the work passes city inspection and walls are patched.

Why Use a Licensed Electrician

Rewiring touches every circuit in your home, so quality and code-compliance matter. A licensed, insured contractor protects you with proper permits, inspection sign-off, and work that won’t jeopardize your insurance or a future home sale.
