TDLR has not yet recorded a final inspection for this project. Therefore, the current state of the site is not confirmed in the public record. While the scheduled completion date of February 2022 has passed, the lack of a final inspection in the TDLR system means that the project's physical completion status remains unverified in the official registry. Readers should note that the registration status reflects the administrative process rather than a real-time view of the construction site.
