Texas Property Code - PROP § 82.160. Conversion Buildings

(a) A declarant of a condominium containing a conversion building shall give each residential tenant or subtenant in possession of a portion of a conversion building notice of the conversion at least 60 days before the date the declarant will require the tenant or subtenant in possession to vacate.  The notice must state generally the rights of tenants and subtenants under this section and shall be hand-delivered to the unit or mailed by certified United States mail, return receipt requested, to the tenant or subtenant at the address of the unit or any other mailing address provided by the tenant or subtenant.  The declarant may not require a tenant or subtenant to vacate on less than 60 days' notice, except for nonpayment of rent, waste, or conduct that violates the rental agreement or is illegal, and the terms of a tenancy may not be altered during that period.  Failure of a declarant to give notice as required by this section is a defense to an action for possession.

(b) If a notice of conversion specifies a date by which a unit or proposed unit must be vacated and otherwise complies with Section 24.005, the notice also constitutes legal notice to vacate on that date for purposes of Section 24.005.  A declarant may not terminate a lease in violation of its terms.

(c) Unless expressly authorized by a rental agreement, a declarant may not make substantial alterations to the interior of a leased premises for purposes of a condominium conversion.
