Improved residential real property — Seller's duty — Format of disclosure statement
Washington's general seller-disclosure statute for residential property transfers. Requires the seller to deliver a completed Form 17 disclosure statement (covering title, water/sewer, structural, systems and fixtures, HOA information, and environmental concerns) to the buyer within five business days of mutual contract acceptance. Distinct from the HOA resale certificate (RCW 64.90.640 / 64.34.425) but typically delivered alongside it.

ESHB 1500 (Chapter 194, Laws of 2026) added a question to the homeowners' association section of the seller disclosure statement in RCW 64.06.020: "Have there been any modifications or remodeling?" and, if yes, "were all necessary homeowners' association approvals obtained?" Effective June 11, 2026. SHB 2239 (Chapter 173, Laws of 2026) adds a further question effective January 1, 2027: "Does the property include a family burial ground, mausoleum, or columbarium?"
| Ref | Requirement |
|---|---|
| (1) | After receiving the seller's Form 17, the buyer has a 3-business-day window to cancel the purchase contract without penalty, simply by delivering a written rescission. This is the statutory cooling-off period tied to the disclosure. |
| (1) | In every Washington residential resale, the seller must deliver the statutory Form 17 disclosure statement to the buyer within 5 business days of the parties reaching mutual acceptance on the purchase contract. Waiver requires the buyer's express written consent. |
| (1) | Form 17 asks about every major property system, title and easement issues, any governing HOA, and environmental conditions the seller knows about. The HOA section covers who can provide the association's records, regular assessments, pending special assessments, and shared common areas. Since June 11, 2026, it also asks whether the property has been modified or remodeled and, if so, whether all necessary association approvals were obtained. |
| (3) | Form 17 reflects only what the seller actually knows — not what the seller should have discovered. It is a disclosure of facts known, not a guarantee, and signing it does not convert the seller's statements into contract warranties. |
