Wisconsin’s Real Estate Disclosure Rules: Navigating Flood Risk Amid Extreme Weather Events

Under Wisconsin law, most sellers must complete and provide a Real Estate Condition Report (RECR)—also known as the seller’s disclosure form—which must be delivered to the buyer no fewer than 10 days after accepting an offer, though providing it earlier is encouraged.

The RECR includes a direct question: Is the property in a flood zone or floodway? and does it have any history of flooding, especially in the basement? Sellers must answer these honestly to the best of their knowledge.

2. Disclosing Known Flood Damage: Full Transparency Required

Wisconsin law mandates that sellers disclose any known flooding or flood damage, regardless of when it occurred. This includes historic events, no matter how long ago. If you knew about a flood—even before you owned the property—you must disclose it.

This responsibility extends to detailing the extent of damage, repair work performed, and any methods used to prevent future issues. Being precise and transparent helps avoid legal challenges and fosters trust.

3. Amending RECRs When New Issues Arise

Should flooding occur after an offer has been accepted but before closing, the transaction is governed by the Property Damage Between Acceptance and Closing clause. Sellers aren’t legally required to amend their RECR mid-transaction, but may choose to do so—understanding that doing so can give buyers rescission rights.

However, if you become aware of issues before acceptance that change responses on your RECR, the law requires you to amend the report.

4. When to Disclose: Timing Matters

While Wisconsin law sets a 10-day post-acceptance minimum for providing the RECR, many sellers opt to share it earlier—even before offers are submitted—to prevent surprises and ensure transparency.

5. Seller and Agent Liability: Know Your Role

False or omitted disclosures can lead to legal consequences—including contract rescission, civil liability, and potential lawsuits for damages.

Real estate agents, as fiduciaries, must disclose any material adverse facts they know, even if the seller has not included them in the RECR.

6. Flooded Wells: Safety Comes First

A property with a private well that’s been flooded must be handled with care: buyers are strongly advised to have the water tested and treated. Sellers should encourage testing and may need to negotiate well-water inspection and remediation as part of the sale.

7. Federal vs. State Disclosure: Focus on Flood Risk

There is no federal requirement to disclose flood risk or past flood damage; such obligations are managed at the state level, and Wisconsin is among the 35 states that mandate flood-related disclosures.

8. Best Practices for Sellers After Extreme Flooding Events

In the wake of unprecedented flooding—like the “1,000-year” event in Southeast Wisconsin—sellers should:

  • Complete (or update) the RECR with all relevant flood history.
  • Disclose details: when flooding occurred, how serious it was, what was repaired, and whether flood mitigation efforts were made.
  • Consult legal counsel or your real estate agent for complex situations (e.g., “as-is” listings, substantial damage, or mid-sale discoveries).

Likewise, buyers should:

  • Review the RECR carefully and ask for clarification.
  • Seek third-party verification via inspections, flood maps (e.g., FEMA), or insurance claim histories (CLUE report).
  • Include contingencies for well testing, flood insurance, or additional inspections when flooding is a concern.

Final Thoughts

With climate volatility ramping up—and “1,000-year” flooding no longer theoretical—Wisconsin’s real estate disclosure requirements are more important than ever. The Real Estate Condition Report (RECR) serves as a critical tool for truth and transparency in the marketplace, especially concerning flood risk.

Both sellers and buyers must approach disclosures with diligence. Sellers should not minimize or omit flood details—even if repairs are complete. Buyers should scrutinize disclosures, investigate the property’s flood history, and account for future risks and costs.
