In 1907, Dr. Edwin Granger purchased land in what is now known as "Grangerland" with the intention of starting a community in the area.[2] Dr. Granger and his fellow settlers made their living by farming cotton, selling limited lumber, and cutting railroad ties.[1][2]
In 1931, during the Texas oil boom, oil was discovered in the area. To accommodate the influx of oil workers, Don D. Granger, Dr. Edwin Granger's son, built a group of houses called, "Granger's Camp."[1][2] As the area continued to expand in the 1940s and 1950s, the area surrounding the camp became known as "Grangerland."
As an unincorporated community, local administrative responsibilities are managed by Montgomery County, Precinct 4. As of June 2023, the commissioner for Precinct 4 is Matt Gray.[16] Caney Creek Fire and Rescue operates a fire station within the community.[17]
Residents of Conroe ISD (and therefore Grangerland) are served by the Lone Star College System (formerly North Harris Montgomery Community College).[20]
