Located at 4858 Lockheed Ln, the work includes an apron expansion and the addition of 36 parking stalls.

Project Scope and Timeline

Construction was scheduled to begin in March 2024, with a planned completion date of January 2026. TDLR completed plan review in December 2024. Although the scheduled completion date has passed, the Texas Department of Licensing and Regulation has not yet recorded a final inspection, meaning the current state of the site is not confirmed in the public record. The project status remains Review Complete, but final verification of the finished work is pending in the official database.

This renovation is part of a broader portfolio for Mark Butler, who has two other TDLR-registered projects in Conroe totaling $360,000. One project, the ATP Flight School location in Conroe, is closed, while the other, Revisions to Hangar 6A, is registered. In Denton County, this project’s estimated cost is above the county median of $235,000 for similar renovation and alteration filings. The scheduled build window of 671 days is longer than the county median of 92 days, reflecting the scale of the apron and parking infrastructure work compared to typical interior renovations.

The facility is situated in ZIP code 76207, an area with a population of about 18,252 and a median household income of $91,026 according to U.S. Census estimates. The housing market in this zip code is mostly owner-occupied, with a median home value of $361,400. Nearby registered projects in the same area include Golden Point, Tetra Pak Product Development Center, and several Denton Crossing buildings, indicating active development in the region. The Denton County unemployment rate was 4.2 percent in August 2026, providing context for the local labor market during this construction period.
