Seller Electrical Disclosures in Marin: What You Must Tell Buyers

California requires you to disclose known material facts — information that could affect a buyer’s decision or the home’s value — and known electrical defects generally qualify. That includes a failing or problem-brand panel, recurring electrical problems, known hazards, past unpermitted electrical work, and older wiring types like knob-and-tube or aluminum branch circuits that you’re aware of. You aren’t expected to disclose things you genuinely don’t know, but you can’t conceal what you do know. Your agent or attorney guides how these go into the formal disclosure statement.

Known unpermitted work is generally a material fact and should be disclosed — and practically, it’s usually discovered anyway by inspectors, appraisers, or through permit records. Disclosing it up front is both the legal course and the strategic one, because a surprise late in escrow damages trust and your negotiating position far more than an honest disclosure. Many sellers address unpermitted work before listing — having it inspected and permitted retroactively where possible — so it’s resolved rather than looming. Consult your agent or attorney on your specific situation.

If you know your home has it, it’s typically disclosable, because both affect safety, insurability, and value — exactly the kind of material fact buyers want to know. Knob-and-tube and aluminum branch wiring frequently come up during inspections and insurance underwriting, so disclosure aligns with what will surface anyway. If you’re unsure whether your home has these wiring types, an assessment can tell you, which lets you disclose accurately rather than guessing. As always, your agent or attorney advises on the formal disclosure.

You can only disclose what you know, so genuine lack of knowledge isn’t a violation — but for an older Marin home, it’s often worth finding out before listing. A pre-sale electrical assessment tells you what you’re working with, so you can disclose accurately and decide whether to fix issues on your terms. It also prevents the awkward situation of a buyer’s inspector surfacing something significant you could have addressed. Knowing your home’s condition puts you in control of both the disclosure and the negotiation.

Usually less than hiding them. Buyers respond far worse to problems their inspector uncovers — which reads as a seller either careless or concealing — than to issues disclosed openly up front, which read as an honest, well-managed home. A disclosed, documented issue becomes a negotiable line item; an undisclosed one discovered at inspection can blow up trust and the whole deal. Many sellers strengthen their position further by addressing known items before listing. Transparency generally protects the sale rather than harming it.

It depends on the issue, your budget, and your market, and it’s worth discussing with your agent. Safety items and things certain to be flagged — a failing panel, unpermitted work — are often best handled before listing, since fixing them on your terms usually costs less and preserves your leverage compared to negotiating under an escrow deadline. Smaller or purely cosmetic items may simply be disclosed. The common thread is knowing your home’s actual condition first, which an assessment provides, so you can decide deliberately.
