Measured from surrender, subject to the forwarding-address rule.
The refund/itemization obligation is not triggered until the written address is provided.
Section 92.109 contains a presumption tied to failure to refund or itemize by the statutory deadline.
30-day security deposit deadline
Enter both dates. The practical calculation uses the later of surrender and the written forwarding-address date, then adds 30 calendar days.
Educational calculator only. The legal trigger can depend on the facts surrounding surrender and delivery of the written forwarding address.
Why two dates matter
For a practical deadline check, keep both the date you surrendered the premises and the date you gave the landlord a written forwarding address. If the forwarding address came later, the landlord’s statutory obligation was not triggered before that notice.
Advance move-out notice can also matter
Section 92.103 says a lease requirement for advance notice of surrender as a condition of refund is effective only if that requirement is underlined or printed in conspicuous bold type in the lease.
Preserve proof
- Proof of key return or possession surrender.
- A copy of the forwarding-address letter, email or other written notice and proof of delivery.
- The envelope or timestamp showing when the refund or accounting was sent.
- Any lease clause requiring advance move-out notice.
