FSBO Wisconsin Laws Disclosure Requirements: Complete 2026 Guide

You must deliver a written Residential Property Disclosure Statement (RPDS) within 3 business days of accepting an offer, disclose any known material defects, and provide the Lead‑Based Paint Disclosure if the home was built before 1978. Skipping any of these steps can stall closing or expose you to legal liability.

2. Detailed Walk‑through of Each Form

2.1 Residential Property Disclosure Statement (RPDS)

• Structure: 45 yes/no/unknown questions covering roof, foundation, HVAC, plumbing, electrical, and known environmental hazards.
• Key Sections:
  1. Structural Elements , foundation cracks, roof age, past water intrusion.
  2. Mechanical Systems , furnace service history, water heater age, sewer line condition.
  3. Environmental Concerns , mold, asbestos, underground storage tanks.

Tip: Answer “unknown” only when you truly have no knowledge. Adding a brief note (e.g., “No inspection performed in 2022”) shows good faith and reduces buyer pushback.

2.2 Lead‑Based Paint Disclosure

• Mandatory for homes built before Jan 1 1978.
• Must include:
  1. EPA’s lead‑based paint pamphlet.
  2. Statement of known lead‑based paint hazards.
  3. Buyer’s acknowledgment of receipt.

If you are unsure of the construction year, request a copy of the original building permit or consult the county assessor’s records.

2.3 Radon Disclosure (Optional but Recommended)

• Wisconsin recommends testing any home built before 1990.
• Place a passive radon test kit in the lowest lived‑in level for 48 hours.
• Attach the lab report to the RPDS packet.

Even if the result is “below 4 pCi/L,” providing the data builds buyer confidence and can speed up negotiations.

2.4 HOA Documents (Condo/Townhouse)

• Include CC&Rs, budget, pending litigation, and reserve study.
• Wisconsin law requires the seller to give these documents at least 7 days before closing.

Wisconsin law is uniform statewide, but some counties maintain additional “local hazard” disclosures (e.g., floodplain maps in Dane County). Before finalizing your packet, call the county clerk or check the county website for any supplemental forms.

8. After the Buyer Signs

1. File the signed RPDS with your title company.
2. Update Sellable to “Disclosures Completed.”
3. Monitor buyer’s inspection period for any new defect claims. If a new issue emerges, amend the RPDS and resend the updated version,Sellable logs the change automatically.

Frequently Asked Questions

1. Do I need a separate disclosure if I’m selling a condo?
Yes. The RPDS still applies, and you must also provide the HOA’s financial statements, bylaws, pending litigation documents, and any recent meeting minutes.

2. What if I truly don’t know about a defect?
Mark the answer “unknown” and add a note with the last date you inspected the component. Offer the buyer a chance to conduct their own inspection within the contractual inspection window.

3. Can I hand‑write the RPDS instead of printing it?
Hand‑written forms are acceptable if legible and signed on each page. Digital signatures work too, provided both parties agree in writing.

4. Does the buyer keep a copy of the RPDS after closing?
The buyer receives a copy at signing and retains it for their records. You should keep a signed copy for at least three years in case of future disputes.

5. How do I prove I met the 3‑day deadline?
Save email timestamps, use Sellable’s “sent” log, or obtain a signed delivery receipt from the buyer. Any of these records satisfy the statutory requirement.
