Pricing: Starting $99/month

Time Required: Listing documentation package in one workflow

The Problem

Washington's RCW § 64.06 mandates a specific property condition disclosure with categories that listing agents and sellers commonly underestimate. Missing or incomplete disclosures on water, septic, environmental hazards, or known structural defects are among the most common sources of post-closing claims in Washington.

The Solution

BuildMyListing prepares the listing documentation layer for Washington transactions — Fair Housing-scanned MLS copy, California-grade photo alteration tracking, and a compliance summary that documents the disclosure conversation. Use alongside the state-prescribed RCW § 64.06 form.

Key Features

Disclosure Category Coverage

BuildMyListing prompts capture the disclosure categories Washington sellers typically need to address: title and ownership, water source and quality, sewage and septic systems, and other material conditions.

Benefit: Complete documentation before listing day

Lead-Based Paint Federal Addendum

For Washington homes built before 1978, the federal EPA/HUD lead paint disclosure (42 U.S.C. § 4852d) is required in addition to any state disclosure. BuildMyListing flags pre-1978 properties and includes the lead paint checklist in the documentation package.

Benefit: Never miss the federal overlay on older homes

Fair Housing Listing Copy

Generated MLS descriptions, headlines, and social captions are scanned against the seven federal Fair Housing Act protected classes (42 U.S.C. § 3604) plus any state-level additions before content is shown to the agent.

Benefit: Reduce Fair Housing complaint exposure on Washington listings

MLS-Ready Listing Package

Generate enhanced photos, MLS descriptions, and marketing flyers in the same workflow — not a separate system. California-grade photo alteration tracking is built in even for non-California listings, creating a defensible audit trail for any AI-altered photo.

Benefit: From listing appointment to MLS-ready in one session

Common Use Cases

Washington Resale with Pre-1978 Construction

Process: BuildMyListing flags pre-1978 construction → Includes the federal lead paint addendum reminder in the package → Documents the disclosure conversation → Generates a compliance summary

Compliance: Federal 42 U.S.C. § 4852d documented alongside RCW § 64.06 categories

Washington Listing with AI-Enhanced Photos

Scenario: Agent generates virtually staged and enhanced photos for a Washington listing. While Washington does not have a state photo-alteration statute, BuildMyListing applies California-grade tracking by default.

Process: Upload originals → Enhance and stage → BuildMyListing logs every alteration → Public disclosure page and QR code generated → Agent can elect to attach to the listing for transparency

Compliance: Defensible audit trail of every AI alteration, available for the broker file regardless of whether the state mandates it

Frequently Asked Questions

What is Revised Code of Washington (RCW) § 64.06 (Form 17 — Seller Disclosure Statement) and who must comply?

Revised Code of Washington (RCW) § 64.06 (Form 17 — Seller Disclosure Statement) requires sellers of residential real property in Washington to provide a written property condition disclosure to buyers, typically before the purchase agreement is signed. The state-prescribed form covers structural systems, mechanical systems, environmental hazards, water and sewage, and other material conditions of the property.

What happens if a Washington seller fails to deliver the disclosure?

RCW § 64.06.030 provides the buyer with 3 business days to rescind after receiving Form 17. If the seller does not deliver Form 17, the buyer may rescind at any time before closing.

What categories must Washington sellers disclose?

Under RCW § 64.06, sellers typically must disclose: Title and ownership; Water source and quality; Sewage and septic systems; Structural condition including foundation and roof; Systems and fixtures including HVAC, plumbing, electrical; Environmental hazards including asbestos, lead, radon, and underground storage tanks; Homeowner association assessments; Manufactured / mobile home specifics. Sellers must disclose known conditions even if repairs have been made. The standard form (Form 17 — Real Property Transfer Disclosure Statement (statutory form under RCW § 64.06.013)) is the practical mechanism for capturing each category.

Does the federal lead-based paint requirement apply to Washington homes?

Yes. The federal EPA/HUD Lead-Based Paint Disclosure Rule (42 U.S.C. § 4852d) applies to any sale of residential housing built before 1978 in all 50 states, including Washington. Sellers must provide the EPA pamphlet 'Protect Your Family From Lead in Your Home,' complete a lead-based paint disclosure form, and give buyers a 10-day inspection opportunity. This applies in addition to RCW § 64.06.

Does Washington require AI photo alteration disclosure?

As of early 2026, California is the only state with a statutory AI photo alteration disclosure regime (effective January 1, 2026). Washington does not currently have an equivalent. However, the federal FTC's general prohibition on deceptive advertising and applicable local MLS rules may still require disclosure of substantially altered listing photos. BuildMyListing applies California-grade tracking by default so the audit trail exists if needed.

What Fair Housing protected classes apply to Washington listing descriptions?

The federal Fair Housing Act (42 U.S.C. § 3604) protects seven classes nationwide: race, color, national origin, religion, sex, familial status, and disability. Washington may add state-level protected classes under its own civil rights statutes. Listing descriptions in Washington must avoid language that expresses a preference, limitation, or discrimination based on any protected characteristic.

Are there exemptions from the Washington disclosure requirement?

Most state property condition disclosure statutes — including RCW § 64.06 — exempt sales by court order, foreclosure sales, sales between family members, sales by an estate or trust, and certain new construction sales (which are governed by other disclosures). The exemptions are narrow, and most standard resales between unrelated parties require the full disclosure. Consult a licensed Washington real estate attorney for transaction-specific exemption questions.

Does BuildMyListing provide legal advice on Washington disclosures?

No. BuildMyListing is a compliance documentation tool that creates an audit trail of photo alterations and a written record of the disclosure conversation. It does not replace the state-prescribed Form 17 — Real Property Transfer Disclosure Statement (statutory form under RCW § 64.06.013), and it does not provide legal advice. Consult a licensed Washington real estate attorney for questions about your specific disclosure obligations.
