Built around an 1857 pioneer settlement, Janesville grew into a small Lassen County community in the Susan River valley, southeast of Susanville. It stands near Honey Lake, where northeastern California’s high-desert basin meets the wooded slopes of the Sierra Nevada. Janesville briefly served as Lassen County’s first seat after the county was established in 1864, before county government moved to Susanville. State Route 36 passes through the community, connecting it with Susanville and the wider interior of northeastern California.
