Do you have to disclose mold when selling a house?
Yes, you usually have to disclose mold when you know about it and your state disclosure form or law asks about mold, moisture, environmental hazards or a similar condition. Indiana's form asks about mold and moisture or water problems. Ohio's form asks about water intrusion, mold inspections, inspection reports and remediation undertaken. Tennessee's statutory form asks about environmental hazards. An as is sale may affect repairs, but it is not the same as disclosure.

Get my cash offerThe basic rule
The exact answer depends on the state and the disclosure form used for your sale. Indiana, Ohio and Tennessee use written disclosure sources with different wording.
Most of the cited rules turn on what the seller actually knows. Indiana refers to the known physical condition of the property, and Ohio refers to actual knowledge.
Mold may appear on the form as mold, water intrusion, moisture, environmental hazards or a similar condition. The safest plain English answer is to treat known mold and moisture history as disclosure issues, not just repair issues.
How the states covered here handle mold and moisture
The state forms and statutes do not all use the same words. This comparison shows what the cited source says and what a seller should notice when filling out a disclosure.
| State | What the cited source says | What it means for mold disclosure |
|---|---|---|
| Indiana | Indiana's form says state law generally requires sellers of one to four unit residential property to complete the form about the known physical condition of the property. The form asks about hazardous conditions such as mold and about moisture or water problems. | Known mold, prior mold conditions and moisture or water problems fit the topics asked on the Indiana form. |
| Ohio | Ohio Revised Code 5302.30 requires a completed property disclosure form for many residential transfers. The Ohio form asks about water leakage, water accumulation, excess moisture, mold inspections, inspection reports and remediation undertaken. | Known water intrusion and known mold inspection or remediation history should be answered on the Ohio form when the question applies. |
| Tennessee | Tennessee's statutory form says anyone transferring title to residential real property must provide information about the condition of the property. The form asks about environmental hazards. | Known mold may matter if it fits an environmental hazard question or another question on the form. |
What an as is sale changes, and what it does not change
An as is sale can change repair promises, but it is not the same issue as disclosure. Tennessee's statutory form says a sales agreement can supersede the form as to repair obligations and the buyer's obligation to accept items as is.
Ohio goes further on concealment. Ohio Revised Code 5302.30 says the listed form items do not limit disclosure duties that may exist to preclude fraud by misrepresentation, concealment or nondisclosure.
Past mold work, reports and moisture history
Past mold work matters most clearly when the form asks about past conditions. Indiana asks, "Have there been or are there any hazardous conditions" and includes mold in that question.
Ohio is also specific about past mold related information. Its form asks whether the property has ever been inspected for mold by a qualified inspector and, if yes, asks the owner to describe any report and remediation undertaken.
Water questions can matter even if the word mold is not the first issue on the page. Indiana asks about moisture or water problems, and Ohio asks about water leakage, water accumulation and excess moisture.
Tennessee's cited form uses a broader environmental hazard question.
Selling without making mold repairs
Disclosure is not the same as agreeing to fix the problem. Tennessee's form says the sales agreement controls repair obligations or the buyer's obligation to accept identified items as is.
If you do not plan to make repairs, the disclosure still needs to match the state form and what you actually know. A seller can compare sale routes with cash offer vs listing agent or review how much it costs to sell a house before choosing how to sell.
One neutral option is selling to a cash buyer, especially when a seller does not want to complete repairs before closing. That choice does not replace the disclosure form or any state rule that applies to the property.
When state rules use different words
Do not assume another state's mold wording applies to your house. Indiana names mold in its hazardous conditions question, Ohio asks about mold inspections and remediation, and Tennessee's cited form asks about environmental hazards.
Because these sources use words like actual knowledge, environmental hazards, excess moisture and mold, the wording of the form matters. Read the exact question before answering, and do not treat mold, water intrusion and prior remediation as separate from disclosure if the form asks about them.
Frequently asked questions
Do I have to disclose mold if the buyer says they will take the house as is?
Usually yes, if your state form or law asks about mold, moisture, environmental hazards or a similar condition and you know about the issue. Tennessee's form treats repair obligations and buyer acceptance as contract issues, but the form still serves as the seller's disclosure. Ohio law also addresses concealment.
Do I have to disclose mold that was already remediated?
It depends on the state form and what the form asks. Indiana asks whether there have been or are hazardous conditions, including mold. Ohio asks whether the property was ever inspected for mold and asks for any report and remediation undertaken if the answer is yes.
Does Ohio ask about mold when selling a house?
Yes. The Ohio Residential Property Disclosure Form asks whether the property has ever been inspected for mold by a qualified inspector and asks for any report and remediation undertaken if the answer is yes. It also asks about water leakage, water accumulation and excess moisture.
Does Tennessee's disclosure form specifically say mold?
The Tennessee statutory form passage cited here asks about environmental hazards, with examples such as asbestos, radon gas, lead based paint, fuel or chemical storage tanks and contaminated soil or water.
Do I have to get a mold inspection before filling out a seller disclosure?
This page does not give testing advice. Ohio's form asks whether you ever had the property inspected for mold, which is different from saying every seller must get a new inspection.
