More historic than 30% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Lewisville is more historic than 30% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Lewisville’s 0.0 sits below most of its state (27% of Washington 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. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
