All residential zones are classified as Rural, Single or Medium density. Most housing developments are tract-based and were completed prior to the 1990s. No further tract-based construction projects have been built in 20 years, with most new construction done individually on privately owned lots. An attempt to construct a golf course and install utilities for residential/commercial zones called "Rancho Lucerne" began grading north of the high school site before embezzlement charges filed against the financier caused the project to shut down in 2001, leaving the site abandoned and desert habitat destroyed.
