HistoryA character grade: shown, never part of Malibu’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 Malibu’s 4.8 sits above most of its state (87% of California towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to B−. The pre-1940 share (±1.5 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Malibu’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The area is within the Ventureño Chumash territory, which extended from the San Joaquin Valley to San Luis Obispo to Malibu, as well as several islands off the southern coast of California. The Chumash called the settlement Humaliwo or "the surf sounds loudly". The city's name derives from this, as the "Hu" syllable is not stressed.
Humaliwo was an important regional center in prehistoric times. The village, which is identified as CA-LAN-264, was occupied from approximately 2500 BCE. It was the second-largest Chumash coastal settlement by the Santa Monica Mountains, after Muwu (Point Mugu). This pre-colonial village was next to Malibu Lagoon and is now part of the State Park.
