Old wiring is an insurance problem before it is anything else
LA housing stock is old enough that three wiring eras are still common in the walls, and insurers flag all three. Rewiring fixes the risk and the paperwork at the same time.
Knob and tube
Common in homes built before about 1940. No ground, aging insulation, and often buried under attic insulation where it cannot shed heat. Many carriers will not write a policy on it at all.
Ungrounded two wire circuits
Standard in homes built into the early 1960s. Two prong receptacles, no equipment ground, and nothing protecting electronics or people the way modern circuits do.
Aluminum branch circuits
Used in homes built roughly between 1965 and 1975. The connections loosen and oxidize over time, which is where the fire risk lives. Depending on the house, the fix is a full rewire or approved remediation at every termination.
How I run a rewire
Permit first, then circuit by circuit so the house stays livable during the work. I plan wall and ceiling openings with you before cutting, coordinate patching, and finish with the inspection and a labeled panel.
Escrow or insurance asking questions about your wiring? I put findings in writing after a troubleshooting visit. A rewire often pairs with a panel upgrade since the panel is usually from the same era.
