More historic than 32% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Descanso is more historic than 32% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Descanso’s 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

The Descanso post office opened in 1877, the earliest record of the town by name (U.S. post office records).
Descanso is more historic than 32% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
12% of Descanso’s homes were built before 1940 (Census estimate, ±8.3 points), against a typical 3.4% for a California town; the median home was built in 1974.
