Texas Rent Apportionment & Landlord-Tenant Codes

Statutory Summary: Tex. Prop. Code § 91.001

Texas Property Code Chapter 91 requires 30 days notice. Duty to mitigate damages applies under § 91.006.

Texas Landlord Statutory Duty to Mitigate Damages (Tex. Prop. Code § 91.006)

Texas law provides specific statutory protections regarding lease termination and damages:

  • Mandatory Duty to Mitigate: Under Section 91.006 of the Texas Property Code, a landlord has an unavoidable statutory duty to make commercially reasonable efforts to re-rent the dwelling if a tenant leaves early. A lease provision that attempts to waive this duty is void.
  • Rent Offsets Upon Re-Rental: Amounts collected from a replacement tenant offset the former tenant's ongoing rent obligations for the remaining term, though the departing tenant may remain liable for rent accrued prior to re-letting, legitimate re-letting costs, or rental rate differentials as allowed by the lease and Texas law.
  • Security Deposit Accounting (Tex. Prop. Code § 92.103): Texas landlords must refund the security deposit within 30 days of move-out, provided the tenant provided a written forwarding address.

Frequently Asked Questions: Texas Rent Proration

If you have a fixed-term 12-month lease that ends on the last day of the month and you choose to leave early without landlord consent, you are generally liable for full rent until a new tenant moves in or the term expires. However, if you are on a month-to-month tenancy and provide a lawful 30-day notice under Tex. Prop. Code § 91.001, you are only legally liable for rent through the expiration date of your notice.

Under Texas statutes, landlords must return your security deposit within 30 Days following key surrender, along with an itemized accounting of any deductions made for unpaid rent or lawful repairs beyond normal wear and tear.
