Washington’s seller disclosure statement, commonly called Form 17, requires most sellers of improved residential property to answer specific questions about the property based on their actual knowledge.

It is not a property inspection, a promise that nothing will fail, or a substitute for the buyer’s own due diligence. It is also not a document a seller should complete casually the night before listing.

For sellers in Kirkland, Kenmore, Bothell, and elsewhere on the Eastside, the practical objective is straightforward:

Disclose known material facts accurately, explain the answers that require context, preserve the records supporting those answers, and update the disclosure if material information changes before closing.

I have been preparing my own Kirkland condo for sale. My approach is to treat disclosure as a documentation exercise, not a marketing exercise. Repairing a problem and disclosing the history of that problem are separate decisions. A fresh coat of paint does not erase what the seller knows, and a prior repair does not necessarily mean the property is currently defective.

This article is educational and is not legal advice. Sellers with questions about what must be disclosed, how to describe a disputed condition, or how an exemption applies should consult a Washington real estate attorney.

What is Form 17 in Washington?

RCW 64.06.020 requires a seller of improved residential real property to deliver a completed seller disclosure statement unless the buyer has expressly waived receipt or the transfer is exempt under RCW 64.06.010. The statute prescribes the form and the minimum information it must contain.

The current statutory definition of improved residential real property includes:

That means Form 17 generally applies to ordinary resales of Eastside houses, townhomes, and condominium units, subject to the statutory exemptions and waiver rules.

RCW 64.06.015 is not the condominium section

RCW 64.06.015 governs the seller disclosure statement for unimproved residential real property. It is the form used for residential land that is not improved by a dwelling, condominium, timeshare, or qualifying mobile or manufactured home. It is not the statute that governs an ordinary condominium resale.

For an existing condo unit, the relevant Chapter 64.06 provisions generally include:

A condominium seller may also have a separate obligation to provide a statutory resale certificate under RCW 64.34.425 or RCW 64.90.640, depending on which condominium statute governs the community. Form 17 and the resale certificate answer different questions; I cover the certificate in detail in my resale certificate guide.

What information does Form 17 cover?

The improved-residential disclosure form prescribed by RCW 64.06.020 addresses multiple categories of property information.

These include:

The form instructs the seller not to leave blanks. When a question clearly does not apply, the form directs the seller to use "NA." It also asks sellers to explain affirmative answers to designated questions on attached pages.

The exact form should be completed carefully because different questions ask different things. A question may ask whether:

A seller should not collapse these into one general conclusion that the property is "fine."

Form 17 is based on the seller’s actual knowledge

The statutory form states that the seller is disclosing existing material facts or material defects based on the seller’s actual knowledge at the time the statement is completed.

That has two practical consequences.

First, the seller should disclose what the seller actually knows. A seller should not hide behind "don’t know" when the seller has received reports, invoices, association notices, contractor findings, insurance correspondence, or other information addressing the question.

Second, Form 17 is not represented as a comprehensive professional examination. The statutory form advises buyers to retain qualified experts for a more complete evaluation of the property.

The form does not turn the seller into an engineer, electrician, roofer, surveyor, or building-envelope consultant. The seller should describe the known facts without claiming technical certainty the seller does not possess.

Form 17 is a disclosure, not a warranty

RCW 64.06.020 expressly provides that the seller disclosure statement is for disclosure only. It is not part of the written purchase agreement and may not be construed as a warranty by the seller or any real estate licensee.

That does not make the form unimportant.

The distinction is between disclosing known information and guaranteeing future performance.

Consider this illustrative example:

A seller knows that a plumbing leak occurred beneath a sink two years ago. A licensed plumber replaced the failed connection, and the cabinet was dried and repaired.

A factual disclosure could identify:

The seller does not need to guarantee that the plumbing system will never leak again. The seller should also avoid a statement such as "permanently fixed" unless a qualified professional has provided a basis for that conclusion.

The strongest disclosure is usually factual, dated, and supported by records.

Which property transfers are exempt?

RCW 64.06.010 states that Chapter 64.06 does not apply to several categories of transfers.

The listed exemptions include:

  1. A foreclosure or deed in lieu of foreclosure
  2. A gift or qualifying transfer to certain family members
  3. A transfer between spouses or domestic partners connected with a dissolution
  4. Certain transfers where the buyer held an ownership interest in the property within the preceding two years
  5. A transfer of less than a fee-simple interest, with an exception for a vendee’s interest under a real estate contract
  6. A transfer by a decedent’s personal representative or a bankruptcy trustee
  7. A transfer in which the buyer expressly waives receipt of the seller disclosure statement

The seventh category has an important limitation.

If the truthful answer to any question in the Environmental section would be "yes," the buyer may not waive receipt of that section.

A seller should not assume an exemption merely because the property is being sold by a trust, an LLC, an investor, or someone who did not occupy it. The statutory wording should be reviewed against the exact ownership and transfer structure.

When must the seller deliver Form 17?

Unless the buyer has expressly waived receipt, RCW 64.06.030 requires the seller to deliver a completed, signed, and dated disclosure statement no later than five business days after mutual acceptance of the written purchase and sale agreement, unless the parties agree to a different timeline.

The statutory form in RCW 64.06.020 contains the same five-business-day delivery instruction.

A seller can provide the disclosure earlier. From a transaction-management perspective, completing it before the property is listed can reduce avoidable delays and give the seller time to locate supporting documents.

Early preparation also helps identify questions that require:

The goal is not to create a polished story. It is to deliver a complete and internally consistent disclosure.

The buyer’s three-business-day rescission right

Under RCW 64.06.030, the buyer generally has three business days after receiving the disclosure statement, or another period agreed to by the parties, to either accept the disclosure or rescind the purchase agreement in the buyer’s sole discretion.

To exercise that right, the buyer must deliver written notice of rescission within the applicable period. Upon delivery, the buyer is entitled to the immediate return of deposits and other consideration, less any agreed disbursements, and the purchase agreement becomes void.

If the buyer does not deliver a timely written rescission notice, the disclosure statement is deemed approved and accepted under the statute.

The three-business-day right is tied to delivery of Form 17. It should not be confused with:

Those rights may overlap, but they arise from different statutes or contract provisions.

For a condo transaction, the buyer may have a separate statutory review right after receiving the resale certificate. RCW 64.34.425 generally makes the contract voidable until delivery and for five days afterward, or until conveyance, whichever occurs first. RCW 64.90.640 contains a five-business-day cancellation framework for communities governed by WUCIOA.

What happens if Form 17 is delivered late or not delivered?

RCW 64.06.040 provides that when a required disclosure statement has not been delivered, the buyer’s rescission right continues until the earlier of:

This is subject to any written waiver by the buyer.

After closing, the seller’s statutory duty to deliver Form 17 and the buyer’s rescission rights under Chapter 64.06 terminate. The statute defines closing for this purpose by reference to payment and delivery and recording of the conveyance document.

That does not necessarily eliminate every claim or remedy that might exist under other law. It means the specific delivery and rescission framework in Chapter 64.06 has ended.

What if the seller learns something new after completing Form 17?

A seller’s disclosure obligation does not necessarily end when the initial form is signed.

Under RCW 64.06.040, if the seller later learns from a source other than the buyer or someone acting for the buyer of additional information or an adverse change that makes a prior disclosure inaccurate, the seller must amend the disclosure and deliver the amendment to the buyer.

An amendment is not required if the seller takes the corrective action necessary to restore the disclosure’s accuracy, or corrects the adverse change, at least three business days before closing.

When an amendment is required and the condition is not timely corrected, the buyer generally receives another three-business-day period to accept the amendment or rescind, following the procedures in RCW 64.06.030. If closing was scheduled within that period, the statute extends the closing date until the rescission period expires.

Illustrative amendment example

This example is illustrative.

A seller completes Form 17 on June 1 and states that the seller is not aware of a roof leak.

On June 15, before closing, a new leak appears during rain. The buyer’s inspector did not discover it. The seller learns of it independently.

The original answer may now be inaccurate. The seller should immediately discuss the new information with the seller’s broker and, when appropriate, legal counsel. Depending on whether and when the condition is corrected, an amended disclosure may be required under RCW 64.06.040.

Waiting until the final walk-through is not a disclosure strategy.

What liability standard applies to errors and omissions?

RCW 64.06.050 uses an actual-knowledge standard.

A seller is not liable under that section for an error, inaccuracy, or omission in the disclosure statement when the seller had no actual knowledge of it. The statute also protects a seller who, without actual knowledge of an error, relies on information from a public agency or a person acting within the scope of a professional license or expertise. Listed examples include surveyors, title companies, inspectors, engineers, and contractors.

A similar protection applies to a real estate licensee who lacks actual knowledge of the error, inaccuracy, or omission.

This is why supporting records matter.

If an answer is based on a contractor’s report, engineering opinion, title report, public permit record, or inspection, identify the source accurately. Do not rewrite a qualified professional conclusion into a stronger statement.

For example:

The first statement is limited to the actual test. The second makes a broader claim.

How Form 17 works for condo sellers

A condominium seller should think about disclosure in two layers.

Layer 1: The seller’s knowledge of the unit and property

Form 17 asks the seller to disclose known information about the property. For a condo seller, that can involve:

Part 6 of the statutory form specifically asks whether there is a homeowners’ association, the amount of regular periodic assessments, whether special assessments are pending, whether shared common areas or maintenance agreements exist, and whether HOA approval was obtained for modifications.

Layer 2: The association’s records and financial disclosures

The condo resale certificate is generally prepared by an association officer or authorized agent based on association books, records, and the preparer’s actual knowledge. Depending on the governing statute, it can include:

The seller should not treat the resale certificate as permission to omit what the seller personally knows. The two documents come from different knowledge sources.

The reverse is also true. Form 17 is not a replacement for the association-prepared resale certificate.

What if the HOA will not provide information?

Part 6 of Form 17 asks for association contact information and certain HOA-related facts. RCW 64.06.040(4) states that an HOA’s failure to provide requested information for that portion of the form does not, by itself, constitute the seller’s failure or refusal to provide the disclosure statement.

That does not mean the seller should guess.

A seller can:

A seller should not answer "no" merely because the association has not responded. "No" and "don’t know" communicate different facts.

How I approach disclosure when preparing a property for sale

As I prepare my own Kirkland condo for sale, I separate the process into four parts.

1. Create a property-history file

I would gather the documents that explain what happened during ownership, including:

The purpose is not to attach every document automatically. It is to make sure the disclosure answers are based on the actual record rather than memory alone.

2. Separate condition from cosmetic preparation

Preparing a property for sale may include paint, flooring repairs, lighting changes, cabinet work, caulking, or other improvements.

Those updates should not blur the history of a known material condition.

For example:

The seller should describe the underlying facts, not just the current appearance.

3. Use specific explanations

A useful attachment answers:

An unhelpful attachment says:

Fixed. No issue.

That statement provides almost no factual context and may imply a technical conclusion the seller cannot support.

4. Recheck the form before mutual acceptance and closing

A disclosure prepared weeks before listing can become stale.

Before providing it to a buyer, I would confirm:

I would repeat that review if anything material changes before closing.

Practical disclosure rules for Eastside sellers

Disclose facts, not sales language

Form 17 is not the place to characterize a condition as minor, harmless, normal, or fully resolved without a factual basis.

Use:

Water staining was observed near the bedroom window in March 2025. The HOA arranged exterior sealant work in April 2025. The seller has not observed additional staining since that work. HOA correspondence is available.

Avoid:

Tiny leak completely fixed. Nothing to worry about.

Do not guess at technical causes

A seller may know that water appeared near a window without knowing whether the cause was flashing, sealant, siding, condensation, roofing, or the window assembly.

State what is known. Attribute professional opinions to their source.

Do not confuse "unknown" with "no"

"No" means the seller is affirmatively answering the question in the negative.

"Don’t know" means the seller lacks the knowledge needed to answer yes or no.

The truthful selection depends on the exact question and the seller’s actual knowledge.

Do not omit repaired conditions merely because they look good now

Some Form 17 questions ask about existing defects. Others ask whether an event or condition has occurred. Read the exact wording.

A repair may change the current condition without changing the history.

Keep disclosure consistent across documents

Compare Form 17 against:

A contradiction between documents can become more significant than the underlying condition.

Seller disclosure checklist before listing

Before putting a Kirkland, Kenmore, Bothell, or Eastside property on the market, I would work through this checklist:

  1. Confirm whether Chapter 64.06 applies or an exemption is available.
  2. Use the current improved-residential disclosure form.
  3. Read every question literally.
  4. Complete every field with "yes," "no," "don’t know," or "NA," as appropriate.
  5. Prepare factual explanations for affirmative starred answers.
  6. Review prior inspections, invoices, claims, permits, and warranties.
  7. Confirm HOA dues, assessments, and contact information.
  8. Order the condo resale certificate separately when applicable.
  9. Verify remodel permits and HOA approvals.
  10. Avoid unsupported technical conclusions.
  11. Sign and date the form and all required attachments.
  12. Preserve a copy of exactly what was delivered.
  13. Document the delivery date.
  14. Update the form if new information makes an answer inaccurate.
  15. Seek legal advice when the correct response or required explanation is unclear.

Frequently asked questions

Is Form 17 required for every Washington home sale?

No. RCW 64.06.010 exempts several categories of transfers, including foreclosures, certain family transfers, some dissolution-related transfers, transfers by a decedent’s personal representative or bankruptcy trustee, and transactions where the buyer validly waives receipt. The exact exemption should be confirmed against the facts of the transfer.

Can a buyer waive Form 17 in Washington?

A buyer may generally expressly waive receipt. However, when any answer in the Environmental section would be "yes," the buyer may not waive receipt of that section.

How long does a buyer have to cancel after receiving Form 17?

Unless the parties agree otherwise, RCW 64.06.030 gives the buyer three business days after receipt to approve the statement or rescind the purchase agreement in the buyer’s sole discretion. Written rescission must be delivered within the applicable period.

Does Form 17 guarantee that the property has no other defects?

No. RCW 64.06.020 states that the disclosure is not a warranty. It is based on the seller’s actual knowledge, and the statutory form advises the buyer to use qualified professionals to inspect the property.

Does a condo seller provide both Form 17 and a resale certificate?

In a typical condo resale, both may be required. Form 17 is the seller’s disclosure based on the seller’s knowledge. The resale certificate is prepared from association records under RCW 64.34.425 or RCW 64.90.640, depending on the law governing the community.

Final perspective

Form 17 should not be treated as a liability trap to evade or a checklist to complete with the fewest possible affirmative answers.

For a seller, the safer and more useful approach is:

A clear disclosure does not make a property defective. It helps the buyer understand the property and evaluate the known issues before closing.
