Quick answer: Whole house rewiring costs $8,000–$45,000+ in Los Angeles depending on home size, with wall access — not the wire itself — being the biggest cost driver. APLA Construction (CA Lic #1136359) handles this throughout Greater Los Angeles.
Los Angeles has one of the oldest housing stocks in California, and a lot of it still runs on wiring that predates modern electrical code by decades. If your home has knob-and-tube wiring, aluminum branch wiring, or a panel your insurance company keeps flagging, a whole house rewire is usually the fix — not a patch job. APLA Construction (CA Lic #1136359) rewires homes across Greater Los Angeles, often paired with a panel upgrade or as part of a larger remodel.
A full rewire replaces the branch wiring running from your panel to every outlet, switch, and fixture in the home:
| Item | Typical Cost |
| Small home (up to 1,200 sq ft) | $8,000–$15,000 |
| Medium home (1,200–2,500 sq ft) | $15,000–$28,000 |
| Large home (2,500+ sq ft) | $28,000–$45,000+ |
| Rough cost per sq ft | $4–$9/sq ft, depending on wall access |
The biggest cost driver isn’t the wire itself — it’s wall access. Rewiring during a gut remodel, when walls are already open, costs significantly less than rewiring a finished, occupied home, where the electrician has to fish wire through closed walls and patch drywall behind them.
If you’re already planning a whole house remodel, that’s the cheapest time to rewire — walls are open, so there’s no fishing wire or patching drywall afterward. A standalone rewire on a home you’re not otherwise remodeling costs more per outlet because of the extra wall-access work, but it’s still far less disruptive than most homeowners expect: most rewires are completed in patches, room by room, so the whole house isn’t without power at once.
A whole house rewire requires an electrical permit from LADBS or your local city building department. Expect a rough-in inspection (wiring visible before walls close) and a final inspection once outlets, switches, and the panel connection are complete. APLA pulls all required permits and coordinates inspections as part of the project.
An electrician can identify it during an inspection, but common clues are a home built before 1975, ungrounded two-prong outlets, or warm/discolored outlet and switch covers — insurance non-renewal notices citing your wiring type are also a common trigger.
Yes, partial rewires are common, especially targeting the rooms with the oldest wiring first. A whole house rewire is usually recommended when the wiring type is inconsistent with modern safety standards throughout, not just in one area.
Usually not. Most rewires are done in phases, room by room, so you keep power to most of the house throughout the project — full move-outs are more common when a rewire is happening alongside a larger gut remodel anyway.
Not always, but it’s extremely common on older homes, since a panel old enough to feed knob-and-tube or aluminum wiring is often undersized or a flagged brand (Federal Pacific, Zinsco) that needs replacing anyway.
Often, yes. Many California insurers charge a premium or decline to renew coverage on homes with knob-and-tube wiring, aluminum wiring, or flagged panel brands — replacing them can restore standard coverage eligibility and sometimes lower premiums.
