HistoryA character grade: shown, never part of Brisbane’s overall grade.
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 Brisbane’s 2.1 sits above most of its state (81% of California towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B+. The pre-1940 share is a Census survey estimate (±6.8 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1961.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Brisbane’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The first recorded inhabitants were the Costanoan Indians. They built dome-shaped dwellings of boughs and tules. By 1776, Spanish explorers had arrived and the Franciscan missionaries soon followed leaving numerous large land grants in their wake. With Mexican rule, the lands controlled by the Mission were released to private enterprise.
