If you own an older home in Idyllwild, there’s a decent chance you’ve heard the word “Zinsco” at some point, especially if you’ve bought or sold a home here.
Zinsco electrical panels were commonly installed in homes from the 1950s through the 1970s, which happens to overlap with the construction dates of a lot of homes on our mountain. They’re easy to recognize once you know what you’re looking for, often with narrow breakers and colorful breaker handles.
They’re also something home inspectors routinely flag.
Why Are Zinsco Panels a Concern?
Despite something I hear fairly often, there was never an official government recall of Zinsco electrical panels.
That doesn’t mean they aren’t problematic.
Zinsco panels have a well-documented history of performance and safety concerns. Among the problems associated with them are breakers that may fail to trip properly during an overload or short circuit, overheating, arcing, deterioration of connections, and failures that may not be obvious from simply looking at the panel.
Because of these concerns, a home inspector who identifies a Zinsco panel will typically call it out in the inspection report as a potential safety hazard or recommend further evaluation by a licensed electrician.
What Happens When You Sell a Home With One?
This is where my advice to Idyllwild sellers becomes very practical.
If I know a home has a Zinsco panel, I usually warn the seller before we ever go into escrow that it is almost certainly going to come up during the buyer’s inspection. I consider it a potential selling expense that we should be prepared for rather than an unpleasant surprise halfway through the transaction.
That does not mean there is a rule requiring the seller to replace it.
Every transaction is different.
A buyer may request that the seller replace the panel before closing. In other cases, the parties may negotiate a credit so the buyer can replace it after closing. Sometimes the buyer and seller agree to share the expense. And occasionally a buyer accepts the property without asking the seller to address it at all.
Like most inspection issues, it becomes part of the overall negotiation.
Insurance Can Complicate Things
There is another reason buyers should pay attention to an older electrical panel: insurance.
Some insurance companies will issue a policy and then conduct their own property inspection after the sale closes. If the insurer identifies a Zinsco panel, it may require replacement as a condition of continuing coverage.
That can leave a new homeowner dealing with an expense shortly after purchasing the property, which is one reason I prefer to have the conversation while everyone is still in escrow.
What Does Replacement Cost?
In the transactions I’ve been involved with, I’ve seen electrical panel replacement costs generally fall somewhere between $4,000 and $8,000, depending on the property and the work required.
Replacing the panel isn’t simply a matter of hiring someone to swap out the equipment. Here in Riverside County, the work requires a permit, a licensed electrician, and coordination with Southern California Edison for inspection and approval.
That process should also be factored into the timing of an escrow if the seller agrees to complete the replacement before closing.
The Bottom Line
Finding a Zinsco panel doesn’t mean a home can’t be sold, and it doesn’t automatically dictate who has to pay for its replacement.
It does mean everyone should know what they’re dealing with.
For sellers, I prefer to identify the issue early and prepare for the likelihood that it will become part of the inspection negotiations.
For buyers, it’s important to understand both the potential safety concern and the possibility that an insurance company may eventually require replacement.
Older homes are part of what makes Idyllwild interesting. They also come with their own collection of quirks, outdated systems, and occasional surprises. Knowing about those things before they become a problem makes for a much smoother transaction.
