If you listed a South Kona home before May 22, is the paperwork you signed still true today?
That is not a rhetorical question. It is a legal one, and it has a specific answer under Hawaii law that most sellers, and more than a few agents, have not worked through since a magnitude-6.0 earthquake shook the district that Friday night. The instinct is to treat disclosure as a one-time event: fill out the form, hand it to the buyer, move on. Hawaii Revised Statutes Chapter 508D does not work that way. It builds in a second trigger, one that has nothing to do with whether your house cracked, and everything to do with whether you learned something new about the district you're selling in.
What the disclosure law actually requires
Every seller of residential property in Hawaii has to deliver a Seller's Real Property Disclosure Statement, the SRPDS, before a buyer signs a purchase contract or within ten calendar days after. The statute defines what has to go on that form as "material facts," meaning anything that would measurably affect what a reasonable buyer would pay. Structural condition, water systems, known defects. The seller only has to disclose what they actually know. Nobody is required to hire an inspector before listing.
The part that catches people is Section 508D-4.5, which requires an amended disclosure statement if the seller discovers a new material fact after the original one was delivered. It does not matter if the house is already under contract. It does not matter if the seller thinks the issue is minor. If a fact that would affect value comes to light, the seller has to send an update, and the buyer gets a fresh 15-day window to review it and potentially walk away, according to Hawaii attorney summaries of the statute.
A district-wide earthquake is about as clean an example of "new material fact" as this law was written to cover.
What actually happened on May 22
At 9:46 p.m. on May 22, 2026, an earthquake registered at magnitude 6.0 struck roughly seven miles south of Hōnaunau-Nāpōʻopoʻo, at a depth of about 14 miles. The U.S. Geological Survey attributed it to lithospheric flexure, the slow bending of the Pacific Plate under the sheer weight of the island chain, rather than magmatic activity tied to Mauna Loa or Kīlauea. That distinction matters less for real estate than the shaking itself, which the county's Civil Defense Agency and USGS both logged as strong to very strong across the west side of the island.
The damage counts moved fast, and then kept moving. Mayor Kimo Alameda's emergency proclamation, signed May 27, cited roughly 207 damage reports concentrated across Ka'ū, North Kona, and South Kona. Three days later, The Garden Island reported that the total had climbed to 143 properties, with 78 formally assessed: five homes deemed destroyed under FEMA standards, 34 with major damage, 22 with minor damage, and more than a dozen affected. By June 1, the county's own tally had passed 300 reports, with Civil Defense Administrator Talmadge Magno citing seven collapsed homes.
| Assessment window | Reports | Homes destroyed |
|---|---|---|
| May 27 (emergency proclamation) | ~207 | Not yet classified |
| May 30 (Garden Island, 78 assessed) | 143 | 5 |
| June 1 (Maui Now, Big Island Now) | 300+ | 7 |
The number kept changing for weeks because assessment is slow, site visits are staged, and structural engineers were still working through properties well into June. That is the point a static disclosure form can't capture. If a seller's SRPDS reflects what was known on May 25, it is describing a district that, by the county's own count, looked meaningfully different five days later.
The water catchment problem is its own disclosure item
South Kona's rural parcels rely on catchment systems for household water more than almost anywhere else on the island, and the earthquake hit that infrastructure hard. County officials said many catchment tanks, pipes, or liners either failed outright or were damaged well after the initial shaking. The county's response tells you how serious this got: Parks and Recreation kept the gates at the Hōnaunau Rodeo Arena unlocked from 7 a.m. to 1 p.m. daily so residents without working catchment could access spigots.
A catchment system is not cosmetic. It is the plumbing. If a South Kona listing has a tank that cracked, a liner that failed, or a line that separated, that is squarely within the structural and systems categories the SRPDS asks about, and it is exactly the kind of fact that has to move from "unknown" to disclosed the moment a seller learns of it, even after the form is already in a buyer's hands.
Why the 15-day window is the real friction point
Here is where the mechanics get specific in a way that generic disclosure guides never cover, because generic guides are not written against a live seismic event in a specific district.
Say a South Kona seller delivered a clean SRPDS in April, before the quake. The house didn't visibly crack. The seller has no reason to think anything changed. But if that seller later learns, through a neighbor, a contractor, or their own walkthrough, that a retaining wall shifted or a catchment tank cracked, the amended disclosure duty kicks in regardless of how the property looked on day one of the listing. Once that amended statement reaches the buyer, the clock resets: 15 calendar days to review it and decide whether to proceed or rescind.
An SRPDS signed in April describes an April South Kona. It says nothing binding about the district after May 22, and the statute does not let a seller pretend otherwise.
That reset window is not a technicality to route around. It is the mechanism Hawaii law uses to make sure a buyer's decision to close is based on current information, not information that expired the moment the ground moved.
What this means if you're selling now
If your property is anywhere in South Kona and your SRPDS predates May 22, the practical move is not to wait for a buyer's inspector to find something. It is to walk the property yourself, specifically for the categories the earthquake is known to have affected in the district: foundation and retaining wall cracks, catchment tank integrity, plumbing separations, and any settling around slabs or lanais. If you find something, or if you already know something from a contractor visit or a neighbor's report, an amended disclosure is not optional under 508D-4.5. It is also, frankly, the version of this that protects you. The statute's two-year statute of limitations only starts running from the date of a disclosure that was accurate. An incomplete one does not start that clock in your favor.
If your home was one of the roughly 300-plus properties that filed a damage report with Civil Defense, that filing itself is a fact worth including on the disclosure, along with whatever repair work has since been completed or documented.
What this means if you're buying
If you're evaluating a South Kona listing this fall, ask directly whether the SRPDS was signed before or after May 22, 2026. If it's before, ask whether an amended statement has been issued, and if not, ask why. A seller who filed a damage report with Civil Defense but hasn't updated their disclosure has left a document you're entitled to see completed correctly before you waive any contingencies. This is also a fair moment to request a catchment inspection specifically, given how concentrated the system failures were in this district, separate from a general home inspection.
None of this should read as alarm about South Kona as a place to buy. It's a request for current paperwork on a property that sits in a district where the ground moved six months ago and the damage count took weeks to settle.
The FEMA deadline is a different clock
One more thing worth separating clearly: the federal disaster declaration, FEMA-4936-DR, was approved September 1, 2026, and residents have until November 1, 2026 to apply for individual assistance. That deadline governs federal aid for repairs. It has no bearing on a seller's disclosure obligations under state law. A seller waiting on FEMA funds to finish repairs still owes buyers an accurate, current SRPDS the day the property goes to contract, not the day the repair check clears.
Frequently asked questions
Does every South Kona seller need an amended disclosure, even if their house shows no damage? Only if the seller has learned a new material fact since their original SRPDS was delivered. A property with no known issues and no damage report on file does not automatically need an amendment. The obligation is triggered by new knowledge, not by the earthquake's existence alone.
Can a buyer still rescind if they're already past their inspection contingency? The 15-day rescission tied to an amended disclosure under 508D-4.5 is separate from a standard inspection contingency deadline. Receiving a valid amended statement gives the buyer that review window regardless of where they are in the standard timeline, according to Hawaii attorney summaries of the statute.
Where can a South Kona property owner check the county's official record of their earthquake damage report? Hawaii County Civil Defense maintains the residential and commercial damage report intake described in the county's official earthquake damage notice, which is also the reference point agents can use to confirm whether a specific address is on file.
Selling or buying in South Kona this fall means working with paperwork that has to keep pace with a district still finishing its earthquake assessment.
