If by "auction sale" you mean a sale at foreclosure, no. These laws only apply to the sellers. An owner whose house is subject to foreclosure at auction is not the seller; the trustee under the deed of trust is.
On the other hand, if by "auction sale" you are talking about eBay, then yes.
Mr. Eschen’s interpretation is correct that this is a foreclosure sale. If you are selling the property even in an auction circumstances the highest bidder for yourself with you receiving the funds from the sale I do not believe this situation would relieve your from obligation to disclose.
