You're under contract, the inspection report just landed, and buried in the PDF is some version of this sentence: "electrical panel appears to be a non-professional installation" or "addition does not appear on county records." Your stomach drops. Is the deal dead? Are you now legally responsible for someone else's DIY wiring job from 2011?

Short answer: probably not dead, and not yet your problem — but it's now your decision, and you have real leverage while you're still under contract. This is the reactive version of the unpermitted-work problem: you're past the "how do I spot this before I even offer" stage (that's covered in a separate piece on researching permit history before you make an offer). Here, the inspector already found something, and you need to know what actually happens next: how to verify what you're dealing with, what the real risk is (insurance, resale, and — if it's electrical — safety), what you can ask the seller for, and how it can trip up your financing on the way to closing.

Step one: verify before you panic

A home inspector isn't a code official. Their report is a flag, not a verdict — "this doesn't look professionally done" or "I don't see this addition matching the footprint on file" is an educated guess, not a legal finding. Before you do anything else:

  1. Call the local building/permit department and ask for the property's permit history by address or parcel number. Most jurisdictions have this online now; if not, a phone call or records request gets it (LegalClarity). You're checking whether a permit was ever pulled for the specific work in question, and whether it passed final inspection — a permit that was opened but never closed out ("open permit") is functionally almost as bad as no permit at all, since it means the work was never signed off (Marlyn J. Wiener, P.A.).
  2. Get a licensed contractor or electrician out to look at the specific work, not just a general opinion. You want a written assessment of whether it's safe as-is, what it would take to bring it to current code, and a real cost estimate. This is the document you'll actually negotiate with — "the inspector had a bad feeling" doesn't move a seller; "a licensed electrician says this panel is a fire risk and quoted $4,200 to replace it" does.
  3. Ask your agent or attorney to check what the seller's disclosure said. If the seller knew about unpermitted work and didn't disclose it where your state requires disclosure, that's a separate legal issue on top of the practical one — worth a conversation with a real estate attorney, especially if the work is serious [state disclosure requirements vary — unverified, confirm for your specific state before treating this as legal guidance].

Don't skip this step to save time. A lot of what gets flagged as "unpermitted" during inspection turns out to be a permit that exists but wasn't easy to find online, or work that's genuinely fine and just never got a rubber stamp. You want facts before you start deciding whether this is a $500 problem or a walk-away problem.

Why this actually matters (beyond "it's not official")

Insurance. This is the one that surprises people. Homeowners insurance policies generally assume the house complies with code, and most carry a "faulty workmanship" exclusion — if unpermitted work directly causes a loss (a DIY electrical job starts a fire, botched plumbing floods a floor), the insurer can deny the claim for that specific damage, even under an "ensuing loss" carve-out that might still cover secondary damage elsewhere in the house (LegalClarity). And critically: this applies to you as the new owner even if the work was done by whoever owned the house before you. "I didn't do it, I didn't even know about it" is not a coverage argument — you inherit the compliance problem along with the house (LegalClarity; Local Hero).

Safety, specifically for electrical. A permit and inspection exist so someone qualified checks that a panel isn't overloaded, wiring is rated for its load, and connections aren't a fire hazard behind a wall. Unpermitted electrical work skipped that check entirely, which means nobody — not you, not your home inspector, who typically can't see inside finished walls — actually knows if it's safe. This is the one category on the list where "let's just live with it" carries real physical risk, not just financial risk, and it's worth treating differently from a permit-free deck or a finished basement.

Resale and future refinance. Whatever gap exists now between "what the county thinks this house is" and "what you're actually buying" doesn't go away — it becomes your problem to explain to the next buyer's inspector, and the next appraiser, when you sell or refinance.

Right now, on this loan. This is the part that can actually blow up your closing timeline, and it deserves its own section.

How it can hit your financing

Your lender doesn't just care that the house exists — they care that it's worth what you're borrowing against, and that it's not a liability magnet. Two things commonly happen:

  • The appraisal excludes the unpermitted space. Appraisers working to Fannie Mae/Freddie Mac guidelines generally can't count square footage toward Gross Living Area if it isn't permitted, which can pull the appraised value down meaningfully below what you agreed to pay — one industry estimate pegs a 400-square-foot unpermitted addition losing roughly $120,000 of appraised value in a $300/sq-ft market, though the exact hit depends entirely on your local price per square foot (mykukun, as of early 2026 — figures are illustrative from one lending-industry source, not a GSE-published table;). If the appraisal comes in below your contract price because of this, you're back to the standard low-appraisal playbook: renegotiate, bring extra cash, or walk.
  • Underwriting can flag it outright, especially for electrical, gas, or structural changes — automated underwriting systems can throw a "hard stop" requiring proof of safety compliance before the loan can proceed (mykukun).
  • VA loans have a specific, well-worn path for this. As of a 2017 policy update, a VA appraiser will still appraise a home with a non-permitted addition, but won't assign it any value — the addition is appraised "as is," meaning it doesn't count toward the home's value for loan purposes. From there you generally have three options: get a retroactive permit (architect draws plans matching the existing structure, you open and close a permit — commonly a 4–8 week process), remove the addition, or pursue a VA waiver, which requires a written request, proof the space is safe and habitable, a "hold harmless" letter, and a contractor or engineer's letter certifying it meets code (Hawaii VA Loans, timeline and process may vary by VA regional office —). FHA and conventional loans don't have this exact named process, but the underlying logic — no value for unpermitted space, possible safety-compliance requirement — shows up in similar form.

Translate that into plain terms: if you're financing this purchase (most buyers are), unpermitted work isn't just a negotiating chip with the seller — it can independently threaten your loan approval or the appraised value your loan is based on, on a timeline that doesn't wait for you to make up your mind.

Your actual options, in order of severity

1. Ask for a licensed contractor's sign-off and move on. If the work is minor (a permit-free bathroom vanity swap, a small deck) and a licensed pro confirms it's safe and sound, this is often the lowest-drama path — note it, maybe still ask for a small credit for the hassle, and proceed.

2. Negotiate a credit or price reduction. The standard move: get a real number from your contractor's assessment (cost to bring it to code, or cost of the retroactive permit plus any required corrections) and ask for that as a credit at closing or a price cut. This is the same logic as any other post-inspection negotiation — ask for cash, not a seller-managed repair, since you don't want the seller choosing the contractor for work you'll be living with.

3. Require the seller to pull retroactive permits and pass inspection before closing. This puts the burden and the timeline risk on the seller, which is appealing, but be honest with yourself about your closing date — permitting can take weeks, inspections can fail and need rework, and "before closing" only works if everyone involved (seller, agent, lender) agrees to the delay. If your jurisdiction doesn't allow retroactive permits for the type of work in question, this option may not exist at all — that's exactly why step one (verify with the building department) comes first.

4. Require a licensed contractor's certification as a condition of closing, even without full retroactive permitting — a written statement that the specific work is safe, sound, and doesn't pose a structural or fire risk. This is a lighter lift than a full permit process and can be enough to get comfortable with lower-stakes findings.

5. Walk away. Legitimate if: the work is extensive, it's electrical or structural and nobody can credibly certify it's safe, the jurisdiction won't allow retroactive permitting without a full teardown, the seller won't cooperate on any of the above, or your lender's underwriting flags it as a dealbreaker. You have an inspection contingency for exactly this kind of discovery — using it is not you being difficult, it's the reason it's in your contract.

Whatever you choose, get it in writing with specifics — the exact scope of work, who's certifying it, what happens if the permit or certification doesn't come through before closing, and who's paying for what. "Seller says it's fine" is not a permit, and it's not enforceable after you close.
