Areas zoned to Westbury High include:
Many neighborhoods in southwest Houston, including almost all of Westbury, Post Oak Manor, Marilyn Estates, Willowbend, most of Willow Meadows, Glenshire, Parkwest, Maplewood South, about half of the Westwood subdivision, and parts of Brays Oaks (Fondren Southwest), as well as the Harris County portion of the city of Missouri City.

In 1970 the Westwood subdivision, along with some other White communities, was rezoned from Westbury to Madison High School because of a court ruling.
By 1990, Westbury was about 50% Black, 25% White, 15% Hispanic, and 10% Asian while Madison was 1% White.
In 1992 an attendance boundary shift occurred but Westwood was still in the Madison zone.
The Westwood community advocated for a rezoning to Westbury, and after the community gave a presentation to the HISD board, the board unanimously rezoned the community to Westbury.

As of 2006 many middle and upper class residents of the Westbury attendance zone do not send their children to Westbury; usually they send their children to Bellaire High School, Lamar High School, or private schools.
