Carpenterville post office was established in 1932 and named for the Carpenter family. In 1940, Carpenterville's population was 35. The post office closed in 1944.
When Carpenterville was still on the main route of the Coast Highway, there was a public school, a store, tourist cabins, and a lodge, the Skyline Lodge and Restaurant. The realignment of the highway cut the community off from the main coastal road. By 1990, there was only one house to mark the location of the community, however the USGS still classifies Carpenterville as a populated place.
