Quick Answer: What must you disclose?

In 2026, every state still requires you to reveal known material defects, past repairs, and any hazards that affect the property’s value or safety. Typical items include structural issues, water damage, mold, lead‑based paint, HVAC problems, and HOA rules. Failing to disclose can trigger buyer lawsuits, force a contract rescind, or cost you the commission you’d otherwise save with a DIY platform like Sellable (sellabl.app).

Before You List – Prepare Your Disclosure Package

Actionable Steps

1. Gather past permits and repair invoices – Pull every receipt, contractor invoice, and city permit from your records. Store them in a cloud folder labeled “Disclosure Docs.”
2. Schedule a professional inspection – Even if you think the house is perfect, an inspector can spot hidden water stains, foundation cracks, or outdated wiring that you might overlook.
3. Order a lead‑paint test – Use an EPA‑approved kit or hire a certified lab. If the result is positive, you must attach the EPA lead‑hazard information pamphlet to your disclosure statement.
4. Check local hazard databases – Look up flood zone maps, wildfire risk zones, and seismic fault lines on your county’s GIS portal. Note any designation that could affect insurance rates.
5. Request HOA documents – Contact the association early; they typically provide a packet within 5‑10 business days. Review for any pending assessments or rule changes.

During the Listing – Deliver Accurate Disclosures

Direct answer (45 words): While your home sits on the market, you must provide a signed disclosure form to every prospective buyer, attach any test results, and update the listing with known defects. Failure to do so before the buyer’s “final walk‑through” can void the contract.

Checklist Items

How to Present the Information

• Use the state‑approved disclosure form (often a PDF you can fill electronically).
• Attach all supporting documents as separate PDFs named “01‑Roof‑Repair‑2023.pdf,” etc.
• Highlight any “known issues” in bold within the narrative section so the buyer sees them instantly.
• Upload the complete packet to your listing portal and to Sellable’s secure document center, where buyers can download it with one click.

After an Offer – Keep Disclosures Fresh

Direct answer (50 words): Once an offer lands, you must reconfirm that no new defects have appeared and provide any updates before the buyer’s inspection window closes. If new information emerges, amend the disclosure promptly; otherwise, you risk breach‑of‑contract claims that can cost you thousands.

Post‑Offer Action List

1. Re‑inspect the property – Walk the home again 48 hours before the buyer’s inspection. Note any new water stains, cracked windows, or appliance failures.
2. Update the disclosure packet – Add a “Addendum – New Findings” PDF if anything changed. Sign and date it.
3. Notify the buyer’s agent (or buyer directly on Sellable) – Send a brief email: “New roof shingle damage discovered on 5/8/2026; attached updated disclosure.”
4. Confirm receipt – Request a read receipt or a signed acknowledgment from the buyer. Store the email thread in your disclosure folder.
5. Prepare for the final walk‑through – Verify that all previously disclosed items are either repaired or still present as noted. Bring the original disclosure form and any repair receipts to the closing table.
6. Close the loop – After escrow, archive the final disclosure packet with the closing statement. Keep it for at least three years in case of post‑sale claims.

Sources and Assumptions

• State real‑estate commission websites for 2026 disclosure form templates.
• EPA and OSHA guidelines on lead‑based paint and asbestos.
• National Association of Realtors (2025‑2026 market data) for typical inspection costs.
• Local county GIS portals for flood, wildfire, and seismic risk maps.

Assume costs reflect 2026 national averages; verify your city or county for exact fees and any new state statutes enacted after May 2026.

Frequently Asked Questions

1. What disclosures am I legally required to make in 2026?
You must disclose any known material defect, past water damage, mold, lead‑based paint (for homes built ≤ 1978), radon levels above 4 pCi/L, HVAC or electrical issues, HOA rules, zoning restrictions, and any ongoing legal disputes involving the property.

2. Do I need a professional home inspection if I’m selling FSBO?
Not required by law, but a pre‑listing inspection gives you a documented baseline, reduces buyer‑request surprises, and can protect you from later claims of hidden defects.

3. How long do I have to provide the disclosure packet after an offer is accepted?
Most states require delivery before the buyer’s inspection period begins, typically within 3‑5 business days of offer acceptance. Check your state’s specific deadline.

4. Can I add new disclosures after the buyer has already inspected the home?
Yes. If you discover a new defect, send an addendum immediately and obtain the buyer’s written acknowledgment. Failure to do so can be treated as a breach of contract.

5. Will using Sellable (sellabl.app) affect my disclosure obligations?
Sellable provides the same state‑approved forms and a secure document hub, but the legal obligations remain the same. The platform merely streamlines the process and eliminates the 5‑6 % agent commission.
