No. The seller’s disclosure-notice requirements in the Texas Property Code only apply to sellers of residential property comprising “not more than one dwelling unit;” however, a seller must still disclose known material defects concerning the property. Therefore, it’s a good idea for the owner of a duplex to provide the notice for each side of the duplex.
Any seller should review the seller’s disclosure notice and consider the advantages of disclosing information about the property’s condition before an offer is made. The notice can be a significant risk-reduction tool.
