Certifying Ongoing Improvements (WPI-8)

Please be advised: Effective June 1, 2020, TWIA will no longer accept applications for Certificates of Compliance. At that time, the Texas Department of Insurance (TDI) will begin issuing Certificates of Compliance for completed improvements. This will be in addition to the Certificates of Compliance TDI already issues for new and ongoing improvements.
Certificates of Compliance issued by TWIA will remain valid. Property owners will not have to re-certify their structures in order to remain eligible for TWIA insurance. This change is the result of legislation passed in 2019. Please visit our Changes at TWIA webpage to learn more about this and other legislative changes affecting TWIA.


The Texas Department of Insurance (TDI) administers the Windstorm Inspection Program and issues Certificates of Compliance (WPI-8) for ongoing improvements.

Obtaining a WPI-8 for Ongoing Improvements

To obtain a Certificate of Compliance (WPI-8), an ongoing improvement must be inspected to certify that it is fully compliant with the windstorm building code. Property owners should follow the steps below to obtain a WPI-8:

  • Notify TDI to begin the WPI-8 process before beginning ongoing improvements.
  • Inspections of ongoing improvements may be performed by a TDI appointed qualified inspector; visit the TDI website for a list of TDI appointed qualified inspectors.

Some types of repairs may be minor or involve only a small portion of the structure and do not require a WPI-8. TDI provides a list of items that do not require an inspection on their website.
