Atherton (/ˈæθərtən/ ath-ƏR-tən) is a town in San Mateo County, California, United States. About 7,188 people lived there in 2020. Atherton is known for being a very wealthy area. In fact, its ZIP Code is often ranked as having the highest cost of living in the United States. In 2023, the average home price in Atherton was about $7,950,000. The town's rules usually allow only one single-family home per acre. Also, you won't find sidewalks here.

What is the History of Atherton?

The land where Atherton now stands was once part of a large Spanish land grant called Rancho de las Pulgas.

José Darío Argüello
Californio politician José Darío Argüello, who owned Rancho de las Pulgas starting in 1795.

In the 1860s, the area was called Fair Oaks. Later, in 1923, the town was renamed Atherton. This was done to honor Faxon Atherton, an important landowner from the 1800s.

Why Did Atherton Sue Caltrain?

Atherton has been involved in lawsuits about train projects. The town strongly opposed a plan to add electric lines for the Caltrain commuter railroad. Caltrain serves cities in the San Francisco Peninsula and Silicon Valley.

Residents were worried that the electric lines would mean cutting down many trees. They also feared that closing two road crossings would divide the town. They thought "newer, cleaner, more efficient diesel trains" would be better than old electric lines.

In 2015, Atherton sued Caltrain. The town said Caltrain's environmental study was not good enough. Even though a judge later sided with Caltrain, Atherton continued to express its concerns. The California State Legislature eventually passed a law to help fund the train project.

The Caltrain station in Atherton closed in 2020.

How Does Atherton Manage Land and Housing?

Atherton is known as one of the wealthiest towns in the United States. This is partly because of its rules about land use. Most homes are large and spread out, with at least one acre of land per home. There are no stores, restaurants, or grocery shops in Atherton. You also won't find sidewalks in the town.

For a long time, the town's rules only allowed one single-family home per acre. This helped make home prices very high. Many residents did not want more housing built. However, a new California law called SB 9 changed some of these rules in 2022. This law allows more homes to be built on properties.

In 2022, Atherton stopped a plan to build 131 new apartments. People who want more housing have criticized Atherton for its strict rules. In 2022, California Governor Gavin Newsom mentioned Atherton for its housing policies. The mayor said the town was working on building affordable homes for school staff and teachers.

In 2023, the Atherton City Council approved a plan for 348 new homes. These homes will be for people with different income levels. The town's main goal for land use is to keep its "scenic, rural, thickly wooded residential area with abundant open space" feel.
