Certifying Completed Improvements (WPI-8-C)
Click here to download a helpful infographic on how to apply to TWIA for a Certificate of Compliance for completed improvements (WPI-8-C).
What Qualifies as a Completed Improvement?
A completed improvement is defined as:
- An improvement in which the original transfer of title from the builder to the initial owner of the improvement has occurred; or
- If a transfer under Paragraph (A) is not contemplated, an improvement that is substantially completed.
Substantially completed is defined as:
- An improvement for which the final framing stage, including attachment of component and cladding items and installation of windborne debris protection, has been completed. If the improvement’s windborne debris protection consists of wood structural panels, all the panels must be present at the improvement’s location but need not be installed.
If the improvement does not qualify as completed, it may qualify as ongoing. The Texas Department of Insurance (TDI) issues Certificates of Compliance (WPI-8) for ongoing improvements. Learn more.
Finding an Engineer
TWIA does not maintain a list of Texas-licensed engineers who may certify completed improvements. One possible resource is TDI’s Windstorm System website, which contains a list of TDI Appointed Qualified Inspectors. You may also visit the Texas Board of Professional Engineers website to search for a Texas-licensed engineer that may certify completed improvements.
Please note: TWIA does not employ or contract with Texas-licensed engineers for the purpose of certifying compliance with the windstorm building code related to completed improvements. If you have an issue with or concern about an engineer related to a Certificate of Compliance (WPI-8-C) on a completed improvement, you may contact the Texas Board of Professional Engineers for assistance or to file a complaint.
The Engineer’s Role
A person lacking a WPI-8 for a completed improvement may apply to TWIA for a WPI-8-C. This can be done if a professional engineer licensed by the Texas Board of Professional Engineers:
- Has designed the improvement, has affixed the engineer’s seal on the design, and submits to TWIA on a form prescribed by the Texas Department of Insurance an affirmation of compliance with the applicable building code under the plan of operation; or
- Completes a sealed post-construction evaluation report that confirms compliance with the applicable building code under the plan of operation.
The required information may be provided to TWIA using our online application form or by submitting a completed paper application form to firstname.lastname@example.org. Only a Texas-licensed engineer may submit the online application form.
How long it takes for a Certificate of Compliance (WPI-8-C) to be issued after an engineer has submitted the required information to TWIA varies based on the volume of submissions. The WPI-8-C will be emailed to the requestor of the form and property owner (if email provided) once TWIA has reviewed and approved the form.
