Your carrier flagged aluminum wiring

Four different letters get described as "my insurance dropped me over the wiring," and they do not mean the same thing or start the same clock. Find which one you are holding before you do anything else.

Most homeowners assume the letter means the policy ends soon. In California it usually means the opposite: you have more runway than the tone of the letter suggests, and the runway is written into statute.

California Insurance Code section 678(c)(1) requires an insurer to deliver or mail a notice of non-renewal at least 75 days before a residential property policy expires. Advice written before 2020 often says 45 days, which is the older provision. Use 75.

There is a second half worth knowing. Under section 678(c)(2), if the insurer fails to give you the full 75 days, your existing policy stays in force with no change to its terms for 75 days from the date the notice was actually delivered or mailed. So a late notice does not shorten your window, it moves it. Check the postmark date against your expiration date and count the days. If it comes up short, the California Department of Insurance can review it.

Seventy-five days is enough time to get a written requirement from your carrier, schedule the work, pull a permit, pass inspection, and send the documentation back. It is not enough time to do all of that if you spend the first month waiting to see whether the letter was serious.

Homes built roughly between 1965 and 1973, which covers a lot of Santa Clara County housing stock, frequently carry solid aluminum branch circuit wiring. It was a response to a copper shortage during a building boom. Aluminum expands and contracts more than copper and oxidizes differently, so connections that were tight in 1970 work loose over decades, and a loose connection under load generates heat.

The U.S. Consumer Product Safety Commission studied this and found that homes wired with aluminum branch circuits were far more likely to have a connection reach what it called fire hazard conditions than homes wired in copper. That finding is why the wiring shows up on underwriting checklists at all, and why it tends to be a condition of coverage rather than a pricing adjustment.

Worth separating two things that get confused: the carrier is reacting to the connections, not to the wire in your walls. That distinction is the whole reason a repair short of a full rewire can satisfy them.

Here is the honest version, because a confident answer would be a made-up one. Underwriting rules vary by carrier, change over time, and are not published in a form anyone can cite. What follows is what our team sees across Santa Clara County jobs, not a rule you can rely on.

Full copper rewiring is the method carriers accept without conditions. Pigtailing every connection so each device terminal lands on copper is commonly accepted when it is done comprehensively and documented by a contractor. CO/ALR devices on their own are the option most often rejected as a complete fix, because they address the device terminal and not the splices beyond it.

Notice what that list does not tell you: which one your carrier wants. That is a question with a real answer, and the answer is free. Ask before you spend anything.

Most repairs that fail to satisfy a carrier were done correctly and documented badly. Underwriting never sees your house. It sees paper. Work the paper as deliberately as the wiring.

Sometimes the timing does not work, especially if the notice sat unopened or the scope turned out larger than expected. You are not out of options, and a gap in coverage is worth avoiding because a lapse makes the next policy harder to get.

The California FAIR Plan is the state's insurer of last resort and exists for exactly this. Section 678(e) actually requires your non-renewal notice to point you to it, along with the Department of Insurance's California Home Insurance Finder. FAIR Plan coverage is typically narrower and costs more, and many homeowners pair it with a separate policy to cover what it leaves out.

Treat it as a bridge. Finish the repair, collect the documentation, and take that package back to the standard market. A documented, permitted, inspected repair is a much easier property to write than an undocumented one.
