Hawaii Seller Disclosure Requirements: The Disclosure Statement, the 10-Day Delivery Rule, and the Buyer's 15-Day Right to Rescind

Hawaii seller disclosure requirements come from one chapter of the Hawaii Revised Statutes and one widely used form. Chapter 508D tells you to put every material fact about the house in writing, hand it to the buyer within ten calendar days of contract acceptance, and keep it accurate until the sale records.

This guide walks chapter 508D section by section: material facts, the eight exempt sales, the mapped-area notices, and what happens when something turns up late. Lava zones, cesspools, the federal lead paint rule, and as-is cash sales follow.

What Are Hawaii's Seller Disclosure Requirements?

Hawaii requires the seller of residential real property to give the buyer a written disclosure statement covering all material facts about the property (HRS § 508D-4). The rule lives in chapter 508D, Mandatory Seller Disclosures in Real Estate Transactions.

The chapter applies to any sale of residential real property except the sales listed in § 508D-3 (HRS § 508D-2). A failure to comply does not affect the validity of title to the property sold.

Section 508D-4 states the rule as a prohibition. A seller may not sell unless three things happen:

• The statement is signed and dated by the seller within six months before, or ten calendar days after, the buyer's acceptance of the purchase contract.
• The statement is delivered to the buyer as provided in § 508D-5.
• The buyer acknowledges receipt, and is afforded the opportunity to examine the statement.

Receipt is documented on the contract, in an addendum, or in a separate document, and kept on file for three years (HRS § 508D-12).

What "residential real property" covers

Section 508D-1 defines it as fee simple or leasehold real property holding one to four dwelling units, or a residential condominium or cooperative apartment used primarily as a residence. Leasehold is covered, which reaches much of Oahu's condominium stock.

The standard form and the notices it must carry

Most Hawaii sellers complete the Seller's Real Property Disclosure Statement, a Hawaii Association of Realtors standard form. The chapter does not mandate it, but § 508D-11 requires any disclosure form to carry three notices:

• That the buyer may wish to obtain professional advice and inspections.
• That the information is the seller's representation, not the agent's.
• That the buyer holds rescission rights under the chapter.

An older public copy of that form, revised 4/07, runs five pages and sorts roughly eighty questions into sections on defects, general conditions, improvements, associations, utilities, and condominium specifics. It warns in capital letters that the statement is no substitute for an inspection.

When Is the Disclosure Statement Due, and When Can the Buyer Rescind?

The seller provides the disclosure statement no later than ten calendar days from acceptance of the purchase contract (HRS § 508D-5). The buyer then has fifteen calendar days to examine it and decide whether to rescind. Delivery runs directly from the seller or through the seller's agent.

Rescission is a written act. The buyer delivers written notification inside the fifteen-day period, and the statute is blunt about the alternative: failure to deliver it is deemed acceptance of the statement. A buyer who rescinds properly loses no deposits, which "shall be immediately returned to the buyer."

Section 508D-5(c) lets the parties move those dates. Seller and buyer may agree in writing to reduce or extend the delivery period or the examination and rescission period, and only a written agreement does it.

Condominium sellers run a second clock. Where a recorded declaration governs, § 508D-3.5 adds the bylaws, the declaration, and the association rules, due ten calendar days after both parties receive a current title report. The buyer then gets fifteen days to examine them and rescind.

Who Is Exempt Under HRS § 508D-3?

Chapter 508D does not apply to eight kinds of sales listed in HRS § 508D-3, most of them transfers an ordinary seller never signs.

Two exemptions Hawaii sellers ask about most

The third item can reach an estate sale made under court order, which differs from a sale by heirs already holding title in their own names. Our guide to selling an inherited house in Hawaii explains that difference.

The fourth covers transfers by operation of law, including foreclosure. A homeowner selling before a foreclosure sale is not inside it, because the owner is still the one conveying. Our guide on stopping a foreclosure in Hawaii covers that window.

What Counts as a Material Fact in Hawaii?

A material fact is "any fact, defect, or condition, past or present, that would be expected to measurably affect the value to a reasonable person of the residential real property being offered for sale" (HRS § 508D-1). The statement covers facts within the seller's knowledge or control, facts observable from visible and accessible areas, and anything §§ 508D-4.5 and 508D-15 require.

Good faith and due care, defined

Section 508D-9 sets the standard of care: the seller or the seller's agent prepares the statement in good faith and with due care. The statute defines that as honesty in fact in its investigation, research, and preparation. It may draw on four sources:

• The seller's own personal knowledge.
• Facts provided by governmental agencies and departments.
• Existing reports prepared for the seller by a licensed engineer, land surveyor, geologist, wood-destroying insect control expert, contractor, or other home inspection expert.
• Facts from a managing agent of a homeowners, condominium, cooperative, or community association.

A seller need not engage any of those professionals, and declining to hire one is not an absence of good faith or due care. A report that reaches the buyer after the initial statement counts as an amendment.

Research has its own limit. Except for the mapped-area notices and the association documents, the seller has no duty to examine public records (HRS § 508D-15(d)). The representations run only to the buyer, and are accurate only as of the time made.

Facts the statute lets a seller leave out

Section 508D-8 excludes two categories, and says neither is a material fact here. The first is that an occupant was afflicted with acquired immune deficiency syndrome or AIDS related complex, or had been tested for human immunodeficiency virus. The second is that the property was the site of an act or occurrence with no effect on its physical structure or environment.

Which Mapped Areas and Island Hazards Must a Hawaii Seller Disclose?

Section 508D-15 names five mapped areas, and a property inside one is disclosed as a material fact in the statement (HRS § 508D-15). The five are:

• A special flood hazard area designated on flood maps promulgated by the National Flood Insurance Program of the Federal Emergency Management Agency.
• The noise area shown on state department of transportation maps prepared under Federal Aviation Regulation part 150 for any public airport.
• The Air Installation Compatible Use Zone of any Air Force, Army, Navy, or Marine Corps airport as officially designated by military authorities.
• The anticipated inundation areas designated on the department of defense's emergency management tsunami inundation maps.
• The sea level rise area designated by the Hawaii climate change mitigation and adaptation commission or its successor.

Each county provides maps of those areas by tax map key, where maps exist. Where a boundary line on a large-scale map makes the answer genuinely questionable, § 508D-15(c) construes the ambiguity in favor of a seller who made a good faith effort.

Shoreline parcels carry a separate duty under § 508D-15(b): the seller discloses all permitted and unpermitted erosion control structures, permit expiration dates, notices of alleged violation, and any related fines.

Lava flow hazard zones on the Big Island

Lava zone is not one of the five mapped areas, but it reaches the statement two other ways. The USGS map divides the island of Hawaii into nine lava flow hazard zones, with flows most likely in Zone 1 and least likely in Zone 9. The current version dates to 1992 (USGS Hawaiian Volcano Observatory). A zone that changes what insurers and lenders will do measurably affects value, which makes it a material fact.

The standard form asks outright. Question 53 on the older public copy reads: "Is the Property located in volcanic hazard Zone 1 or 2? (Only applicable to Island of Hawaii)." Question 52 asks about a tsunami inundation area or flood zone. Our guide to selling a house in a lava zone on the Big Island goes deeper.

Cesspools and the 2050 conversion mandate

Wastewater is its own line on the form, which asks what system serves the house, offering cesspool, septic, and individual sewage treatment plant as choices, plus the last pumping date. It also asks whether a cesspool serves more than one dwelling or living unit, including an ohana home.

The answer carries weight because of Act 125 (2017), which requires the replacement of all cesspools in Hawaii by 2050. The Department of Health counts roughly 88,000 cesspools statewide, nearly 50,000 of them on the island of Hawaii, and identifies 43,000 that pose a risk to water resources (Hawaii Department of Health, September 2026). Act 120 of the 2026 session created a statewide conversion revolving loan program, still under development. Kauai County opened a round of fifty $20,000 reimbursement grants closing October 6, 2026 (Hawaii Department of Health, September 2026).

Burial and archaeological sites

Under § 508D-21, a court imposes a $1,000 fine on a private landowner who fails to disclose and record burial or archaeological sites that the landowner knew of or should have known of. Recording runs to the bureau of conveyances, or into the documents used to offer the property for sale.

What Happens If a Material Fact Turns Up Later?

Section 508D-13 answers this, and the answer is an amended statement rather than a violation. Information that becomes known or becomes inaccurate after delivery does not by itself breach the chapter. The duty attaches when it directly, substantially, and adversely affects the value of the property.

The seller then provides an amended statement within ten calendar days of discovery, and no later than twelve noon of the last business day before the recorded sale. The buyer gets fifteen calendar days to examine it, and may rescind if not already aware of the fact.

Section 508D-6 covers the mirror image: a statement that omitted a material fact or carried an inaccurate assertion with that same substantial effect. A buyer who did not know may elect in writing to rescind within fifteen calendar days of the earlier of discovery or a corrected statement.

Remedies, deposits, and deadlines

Section 508D-16 sorts out the money. A buyer may complete the purchase despite noncompliance, and after recordation has no right under the chapter to rescind. A buyer who receives a proper statement and then rescinds gets no damages, but is entitled to the immediate return of all deposits.

Negligence is treated separately. A seller who negligently fails to provide the statement is liable for the buyer's actual damages, and a court may award the prevailing party attorney's fees, court costs, and administrative fees. Section 508D-16.5 adds that any rescission action must commence before the sale records. Section 508D-17 sets an outer limit of two years from receipt, or two years from the recorded sale if none was delivered.

Federal Lead Paint Disclosure for Pre-1978 Houses

Houses built before 1978 carry a federal duty on top of the Hawaii statement, and no state exemption removes it. Section 508D-14 makes room for it: chapter 508D is in addition to all other disclosure obligations required by law. The Residential Lead-Based Paint Hazard Reduction Act, 42 U.S.C. § 4852d, sets the rule EPA and HUD enforce (EPA, Lead-Based Paint Real Estate Disclosure). Sellers of most pre-1978 housing must:

• Give the buyer the EPA pamphlet "Protect Your Family From Lead in Your Home."
• Disclose known lead-based paint and lead-based paint hazards, including the location and the condition of painted surfaces.
• Provide any available records and reports about lead-based paint in the house.
• Allow the buyer a 10-day period for a lead inspection or risk assessment, which the parties may adjust in writing and the buyer may waive.
• Include the Lead Warning Statement and signed acknowledgments in the contract, and keep the signed records for three years.

The Hawaii form touches lead only in passing, listing lead-based paint alongside asbestos, formaldehyde, radon gas, storage tanks, and contaminated soil in one environmental hazards question. Checking that box does not satisfy the federal rule.

Does Selling a House As Is in Hawaii Remove the Disclosure Duty?

No. Selling a house as is in Hawaii is a statement about repairs, not about information. An as-is clause appears nowhere in the eight exempt sales at § 508D-3, so it cannot remove the statement, and it cannot turn a known material fact into an unknown one.

What an as-is clause does not cover is an answer you knew was wrong when you wrote it. The safer sequence for the owner of a single-wall Kaimuki bungalow or a rain-worn Hilo cottage is simple: disclose fully, sell as-is, and let the price carry the condition. Our guide for houses needing major repairs covers the tradeoff.

How a Direct Cash Sale Changes the Conversation

The disclosure statement is still delivered in a cash sale, because nothing in chapter 508D turns on how the buyer pays. The fifteen-day examination and rescission period still runs, unless seller and buyer shorten it in writing under § 508D-5(c).

Propcash is a direct cash homebuyer, founded in 2026 and based in Nashville, and we buy houses across Hawaii as-is. We do not ask a seller to repair what the statement reveals. A cesspool awaiting conversion, a Zone 2 parcel, or a termite-softened floor can be disclosed and still transact.

• You still complete the statement. Fill it out honestly and deliver it inside the ten-day window.
• Your paperwork travels with it. Pumping records, termite treatment receipts, and any engineer's report attach to the answers they support.
• No repair list follows. Propcash buys as-is, so a disclosed condition typically shapes the offer rather than a punch list.
• You pick the closing date. Cash transactions can close in as few as 7 days, or later if probate or a payoff needs room.

Zillow's home value index for Hawaii reads $833,877, up 0.5% year over year, with Honolulu at $765,367, up 1.4%, and Hilo at $566,432, up 5.1% (Zillow Home Value Index, July 2026). You can get a cash offer on your Hawaii house and compare it against a listed sale, or read more about selling a house for cash in Hawaii first.

Frequently Asked Questions

How many days does a Hawaii seller have to deliver the disclosure statement?

No later than ten calendar days from acceptance of the real estate purchase contract, under HRS § 508D-5(a). Section 508D-4 adds a signature rule: the statement is signed and dated within six months before, or ten calendar days after, acceptance.

Can a Hawaii buyer cancel the contract after reading the disclosure statement?

Yes. HRS § 508D-5(b) gives the buyer fifteen calendar days from receipt to examine the statement and decide whether to rescind. Written notice must reach the seller or the seller's agent inside that window, and all deposits are then returned immediately. Silence is deemed acceptance.

Do I still have to give a disclosure statement if I sell my house as is in Hawaii?

Yes, unless the sale is one of the eight exempt sales in HRS § 508D-3. An as-is clause allocates the cost of repairs, and it appears nowhere in that exemption list. The statement is still prepared in good faith and with due care under § 508D-9.

Who is exempt from Hawaii seller disclosure requirements?

HRS § 508D-3 lists eight exempt sales. Four involve the seller's circle or a court: a sale to a co-owner, to a spouse, parent, or child, by devise, descent, or court order, or by operation of law such as foreclosure. Lease-to-fee conversions, chapter 484 initial sales, condominium sales with an unexpired developer's public report, and chapter 514E time share interests complete the list.

Do I have to disclose a lava zone or a cesspool on a Hawaii house?

Neither is named in HRS § 508D-15, but both reach the statement another way. A material fact is any fact, defect, or condition expected to measurably affect the property's value to a reasonable person. The Hawaii Association of Realtors standard form also asks directly about volcanic hazard Zone 1 or 2 on the island of Hawaii and about the wastewater system, including a cesspool.

Does a cash buyer still need the Hawaii disclosure statement?

Yes. Nothing in chapter 508D turns on how the buyer pays or whether an agent is involved, so a direct cash buyer receives the same signed statement and the same fifteen-day period. A cash buyer purchasing as-is typically prices a disclosed condition into the offer rather than returning with a repair list.
