Texas Occupations Code - OCC § 1201.457. Habitability:  Change to or from Nonresidential Use or Salvage

(a) If the sale or exchange of a used manufactured home is to a purchaser for the purchaser's business use, the home is not required to be habitable unless the purchaser discloses to the retailer in writing at the time of purchase that the purchaser intends for a person to be present in the home for regularly scheduled work shifts of not less than eight hours each day.  The purchaser of the home shall file with the department an application for the issuance of a statement of ownership indicating that the home is reserved for a business use.

(a-1) If the sale or exchange of a used manufactured home is for the purchaser's nonresidential use other than a business use, the home is not required to be habitable.  The purchaser of the home shall file with the department an application for the issuance of a statement of ownership indicating that the home is for a nonresidential use other than a business use.

(b) If a used manufactured home is reserved for a business use or another nonresidential use or is salvaged, a person may not knowingly allow any person to occupy or use the home as a dwelling unless the director issues a new statement of ownership indicating that the home is no longer reserved for that use or is no longer salvaged.  On the purchaser's application to the department for issuance of a new statement of ownership, the department shall inspect the home and, if the department determines that the home is habitable, issue a new statement of ownership.
