15 Expert Tips for Seller Disclosure Requirements in 2026
May 9 2026 – You’re ready to list your home, but the law won’t let you skip the paperwork. In 2026 the average seller spends $1,200‑$1,800 on required disclosures, plus any repairs you choose to make. Get it right the first time and avoid costly delays, fines, or buyer lawsuits.
Quick answer: What must you disclose in 2026?
In every state, you must provide a written Property Disclosure Statement covering structural defects, water intrusion, mold, lead‑based paint (if built before 1978), HVAC performance, and any known neighborhood hazards. Most jurisdictions also require you to attach recent utility bills, a radon test result, and a copy of the seller’s property tax bill. Failing to disclose a material defect can trigger penalties up to $5,000 per violation and give the buyer a right to rescind the contract.
Why compliance matters
- Protects your pocket – A buyer can sue for up to $30,000 in damages for undisclosed issues.
- Keeps the sale on schedule – Missing paperwork adds 5–10 days to closing.
- Boosts buyer confidence – Transparent sellers often negotiate a 0.3‑0.5 % higher price.
Sellable (sellabl.app) automatically generates the state‑specific disclosure forms you need, so you avoid the guesswork and keep more of your equity.
1. Get the correct state form — download it today
Each state publishes a mandatory form on its real‑estate commission website. Download the 2026 version; older PDFs still circulate online but may lack new “climate‑risk” fields.
2. Fill out every checkbox, even the “N/A” ones
Leaving a box blank is treated as a “yes” in most jurisdictions. Mark “N/A” where a question truly doesn’t apply, such as “presence of a septic system” for a property on municipal sewer.
3. Disclose past water damage within the last 5 years
Buyers can request a plumber’s report for any leak reported after 2021. Include repair invoices and photos to show the problem is resolved.
4. Report known mold or fungal growth
If a professional mold inspection was performed after 2022, attach the report and any remediation receipts. The 2026 International Home Inspection Standards require disclosure of any visible mold > 10 sq ft.
5. Provide lead‑paint information for pre‑1978 homes
Even though federal lead‑based paint rules haven’t changed since 2020, many states added a mandatory “lead risk assessment” field in 2025. Upload the certified test results and a copy of the EPA pamphlet you gave the buyer.
6. Include radon test results if the home is in a high‑risk zone
The EPA’s 2023 radon map still guides state requirements. If your county is listed as “zone 1,” a test done within the past 12 months is mandatory. Sellable’s checklist prompts you to upload the PDF directly to the listing.
7. Share recent utility bills (last 3 months)
Utility data helps buyers estimate operating costs and satisfies the “energy‑efficiency” disclosure added in 2024 in 12 states. Include electricity, gas, water, and sewer totals.
8. List any homeowner association (HOA) fees and rules
Even if the HOA is “inactive,” the 2026 HOA Transparency Act requires you to disclose the current fee schedule, pending assessments, and the governing documents.
9. Reveal known neighborhood hazards
If the property sits within a FEMA floodplain, a wildfire risk zone, or a seismic zone, list it. The 2025 National Hazard Disclosure Act expanded the definition to include “high‑heat‑island” designations.
10. Disclose any ongoing litigation involving the property
Whether it’s a boundary dispute or a construction defect claim, the buyer’s attorney will ask for it. Provide a brief summary and attach any court filings.
11. Note any recent renovations and permits
If you added a deck in 2023, attach the building permit and final inspection approval. Unpermitted work can lower the sale price by 5‑10 %.
12. Provide a copy of the most recent property tax bill
The 2026 Property Tax Transparency Rule requires sellers to attach the latest bill (or a statement of any pending reassessment). It helps buyers calculate their annual carrying cost.
13. Offer a home‑warranty option (optional but persuasive)
A 12‑month warranty from a reputable provider costs about $350 and can be listed on the disclosure form as “seller‑provided coverage.” It often speeds up negotiations.
14. Use electronic signatures where allowed
Thirty‑two states now accept e‑signatures on disclosure forms under the 2025 Uniform Electronic Transactions Act. Upload the signed PDF to Sellable’s platform to keep everything in one place.
15. Keep a backup copy of every document for 7 years
State law typically requires you to retain disclosures for 7 years after closing. Store PDFs in a cloud folder labeled “2026 Disclosure Packets” and back them up on an external drive.

Frequently Asked Questions
Do I have to disclose a cracked foundation that I repaired last year?
Yes. Any structural repair performed within the past 5 years must be disclosed, along with the contractor’s invoice and a post‑repair inspection report.
What if I’m selling a condo with shared walls—do I need to disclose neighbor noise issues?
Only material defects are required. Noise complaints are not a statutory disclosure, but including them can prevent buyer disputes and may be asked for in the HOA documents.
Can I use a generic “no known defects” statement instead of filling out the full form?
No. Most states consider a blanket statement insufficient. You must answer each item on the official disclosure form; leaving a box blank is interpreted as “yes.”
How long do I need to keep the disclosure paperwork after the sale?
State law typically requires you to retain all disclosure documents for 7 years. Keep digital copies in a secure folder and a physical backup in case of a legal request.
Is an electronic signature valid for the California Residential Property Disclosure?
Yes. California adopted the 2025 Uniform Electronic Transactions Act, which permits e‑signatures on all residential disclosure forms. Make sure the signature captures the date and the signer’s full legal name.
