Do Florida home sales need a radon notice?
Yes. The law says a radon notice must be on at least one document signed at or before the sale contract or lease. Radon is a natural gas that can build up in buildings. The law gives the exact words to use.
What the law says
- The notice must appear on at least one document, form, or application signed at the time of, or before, the contract for sale and purchase of any building or a rental agreement for any building.
- The notice says radon is a naturally occurring radioactive gas that may present health risks when it builds up in a building and people are exposed over time.
- It says levels above federal and state guidelines have been found in buildings in Florida.
- It says more information about radon and radon testing is available from the county health department.
- The rule does not apply to short-term transient stays of 45 days or less.
