Paperwork for Selling a House by Owner in Seattle, WA: 2026 Local Guide

May 4, 2026 – You just received an offer for your Capitol Hill condo and the buyer wants to move fast. Before you sign anything, you need the right forms, disclosures, and city approvals. Missing a single document can stall the closing by weeks or cost you $5,000‑$10,000 in penalties. This guide walks you through every piece of paperwork you’ll need to complete a clean, buyer‑ready sale in Seattle this year.

1. Why the paperwork matters now

Seattle’s 2026 real‑estate climate is tight: inventory sits at 1.3 months of supply, and the average sale price hovers around $950,000. Buyers are demanding transparency, and the city has tightened disclosure rules around flood risk, seismic retrofits, and energy upgrades. A well‑organized packet protects you from post‑sale lawsuits and keeps the transaction on schedule.

2. Core documents you must prepare

Tip: Keep a digital folder on your laptop titled “FSBO Paperwork – Seattle 2026.” Save PDFs with clear names (e.g., “SPDS_2026_03_15.pdf”). Upload the same folder to Sellable’s document vault; the platform automatically notifies the buyer when you add a new file.

3. Seattle‑specific disclosures you can’t ignore

3.1 Flood‑plain and Sea‑Level Rise Notice

Seattle requires a Flood‑Hazard Disclosure for any property within the 100‑year floodplain. The City’s GIS portal shows that neighborhoods like Rainier Beach and parts of West Seattle fall into this zone. Download the latest flood map PDF from the Seattle Department of Construction & Inspections (DCI) and attach it to your SPDS.

3.2 Seattle Energy Code (SEC) Compliance

If you installed solar panels, heat‑pump water heaters, or upgraded insulation after 2020, you must provide the Energy Upgrade Certificate. The SEC mandates a minimum HERS (Home Energy Rating System) score of 75 for new builds; retrofits must meet a 10% improvement over the baseline. The certificate comes from a certified energy rater and satisfies the city’s Energy Disclosure Addendum.

3.3 Seismic Retrofit Disclosure

Seattle’s 1994 ordinance still applies. If you completed a retrofit, you’ll receive a Seismic Retrofit Certificate from a licensed structural engineer. Even if you didn’t, you must disclose that the home has not been retrofitted. Buyers often request a “seismic assessment” after the offer; having the certificate ready can prevent renegotiation.

3.4 Lead‑Based Paint for pre‑1978 homes

The federal rule still holds. Provide the EPA Lead Paint Disclosure Form and a 30‑day inspection report if the buyer requests one. Seattle’s health department offers a low‑cost testing service at $75 per room.

3.5 HOA Packets (Capitol Hill, Queen Anne, Ballard)

If your property belongs to an HOA, you must supply the CC&Rs, bylaws, budget, and meeting minutes from the past two years. The HOA also needs to issue a Letter of No Delinquency confirming that you’re current on dues.

4. Step‑by‑step paperwork workflow

1. Gather historical records – Locate original building permits, renovation receipts, and any prior inspection reports.
2. Download city forms – Visit the Seattle DCI website for the SPDS, Flood‑Hazard form, and Energy Disclosure Addendum.
3. Order required certificates – Hire a certified rater for the EPC and a structural engineer for a seismic retrofit certificate if applicable.
4. Complete the SPDS – Fill out each section truthfully; use “N/A” only when the question truly does not apply.
5. Upload to Sellable – Drag every PDF into the platform’s “Seller Docs” tab; tag each file (e.g., “Energy”, “HOA”).
6. Open escrow – Choose a reputable Seattle escrow company (e.g., Seattle Title, Fidelity National). Provide them with the title commitment and any pending liens.
7. Sign the Purchase Agreement – Use an electronic signature service integrated with Sellable for a legally binding contract.
8. Deliver disclosures – Within 3 business days of the agreement, send the SPDS, flood map, and EPC to the buyer’s agent or directly to the buyer.
9. Address buyer’s requests – If the buyer asks for a new roof inspection, schedule it within 5 days and upload the report.
10. Close – Review the Closing Disclosure, sign the Grant Deed, and pay the King County transfer tax. The escrow officer records the deed and releases funds to you.

6. Common pitfalls and how to avoid them

• Skipping the EPC – Seattle’s 2026 ordinance allows buyers to request a second‑hand energy audit. If you don’t have the original, you’ll pay $300‑$500 for a re‑audit, delaying closing.
• Leaving out a flood‑plain map – The buyer can invoke “failure to disclose material fact,” which may void the contract and force you to return the earnest money.
• Misstating HOA dues – Underreporting dues by even $50 per month can trigger a breach claim. Double‑check the latest HOA statement before you sign.
• Using outdated title search – Liens from a previous contractor can surface during escrow. Order a fresh title commitment within 7 days of the buyer’s offer.
• Failing to record the deed promptly – King County processes recordings in batches; submit the deed within 24 hours after closing to avoid a $250 penalty for late recording.

7. How Sellable makes the paperwork painless

1. Document vault – Upload every form once; Sellable automatically timestamps each file, creating a verifiable audit trail.
2. Checklist builder – The platform generates a customized “Seattle FSBO Checklist” based on your property’s age, location, and HOA status. Tick items off as you complete them.
3. Integrated e‑sign – Buyers sign the Purchase Agreement and disclosures directly in the portal, eliminating the need for third‑party services.

Using Sellable typically saves $3,200‑$4,500 in admin fees compared with a traditional listing that relies on agents to manage paperwork. Plus, you retain the full 5‑6% commission that would otherwise go to an agent.

9. Quick reference cheat sheet (print or save on phone)

• SPDS – Seattle DCI website, PDF, 2 pages

• Seismic Certificate – Structural engineer, $300‑$450
• Flood map – GIS portal, free download

• Transfer Tax – $150‑$300, King County, due at closing

Keep this list in your “FSBO binder” and tick each item as you finish it.

10. When to call a professional

• Complex title issues – If a prior lien exceeds $5,000, a title attorney can clear it faster than you.
• Boundary disputes – A land survey costs $600‑$900; it’s worth the expense to avoid a $20,000 lawsuit.
• Negotiating repairs – A real‑estate attorney can draft a “Repair Addendum” that protects you from buyer‑initiated price cuts after inspection.

You can still run the sale yourself on Sellable while leaning on specialists for these narrow tasks.

Frequently Asked Questions

Q1: Do I need a home inspection before listing?
A: Not required, but providing a recent inspection (within 90 days) can increase buyer confidence and shave 2‑3 days off the closing timeline.

Q2: How much does the Seattle transfer tax cost?
A: The tax is 1.78% of the sale price, split between buyer and seller unless otherwise negotiated. For a $950,000 home, each party pays about $8,460.

Q3: Can I use a digital signature for the Grant Deed?
A: Yes. King County accepts electronically signed deeds if the signature is captured with a qualified electronic signature platform, which Sellable integrates.

Q4: What if my home is in a flood zone but I never received a flood‑hazard notice?
A: You still must disclose the risk. Download the latest FEMA map for Seattle, highlight the zone on a screenshot, and attach it to the SPDS.

Q5: How do I prove I’m current on HOA dues?
A: Request a “Letter of No Delinquency” from your HOA board, have it signed by the board president, and upload the PDF to Sellable. The buyer’s escrow officer will verify it before closing.
