Florida law requires sellers to disclose known material defects that are not readily observable to the buyer and that negatively impact the value of the property. Such defects should be disclosed to prospective buyers. Examples of things sellers need to disclose are termites, wood rot, and water damage.
But what about loud noises? What if the seller’s property is close enough to an airport that you can hear loud noises overhead as planes land? What if the buyer is unaware and never experienced a plane landing while the buyer went under contract to buy the property?
Sellers should generally always disclose any defects, including loud noises. If you are questioning whether you should disclose something, then you probably should disclose it.
Sellers do not have to disclose defects that are obvious. For instance, if the property is located near a loud busy street, then the seller does not need to disclose that the street is noisy. However, if there are train tracks or an airport nearby that the buyer is not aware of, then the seller should disclose those sorts of issues. If noise is enough of an issue to be concerned about, then it should be disclosed to prospective buyers.
I recommend adding a few lines to a written disclosure where the seller makes the buyer aware of the noise. It is best for sellers to err on the safe side and always disclose things that can be potential issues for a buyer.
