The population was 1,557 at the 2020 census.
Ladera is located at the bottom of the eastern slope of the Peninsula Range of theSanta Cruz Mountains.It is bordered on the west by theJasper Ridge Biological Preserveoperated byStanford University, on the east by Alpine Road, and on the north by Webb Ranch.
According to theUnited States Census Bureau, the CDP covers an area of 0.4 square miles (1.1 km), all of it land.
TheRamaytushOhlone peoplesoccupied the land that is now the community of Ladera, prior to the settlement ofCaliforniaby theSpanish.  Ladera is located on theRancho Corte de MaderaMexican land grant.
The land was used for grazing and timber through 1927 when it was joined to the Ormondale Ranch, owned by the Macdonough family.  The Macdonoughs raised cattle and sheep, and bred racehorses; their most famousstud,Ormonde, had raced inEnglandand never lost a race.  In the 1930s, the majority of the Ormondale Ranch land was developed and incorporated into Portola Valley.
In 1944, thePeninsula Housing Association(PHA) was formed with the goal of purchasing a tract of land and developing ahousing cooperative.  Several prominent members of the Stanford andPalo Altocommunities joined to develop the fledgling PHA co-op.  It began subscribing members in 1945 and its 150 members purchased the remaining 260 acres (1.1 km) of the former Ormondale ranch for $155,000 on July 31, 1946. The co-op selected noted landscape architectGarrett Eckboto lay out the design for the new community.Architects Joseph Allen Stein and John Funk were chosen to design several of the earliest model homes.
The members chose the nameLadera(over alternativesLark HillsandNewRochdale) to reflect the Spanish history of the land —laderais Spanish forhillside.  Streets are Spanish phrases or botanical names.  Early members of the cooperative included authorWallace StegnerandKlystron tubeinventorSigurd VarianofVarian Associates.  (Varian had grown up inHalcyon, anotherintentional communityin southern California.)
The PHA refused to placerestrictive covenantsontitle deeds. However, the Federal Housing Administration would not insure loans to co-ops that included African American members - an example ofredlining.Banks would not finance loans or issue mortgages without government approval, so the PHA failed due to financial difficulties after only a few houses had been constructed.The co-op proposed the inclusion of a quota system, promising that the proportion of African American members would not exceed the proportion of African Americans in California's overall population. This stipulation was not sufficient for the government. The land was later sold to Hare, Brewer, and Kelley, who completed the development. Directly following completion, single family homes in the development were only sold to whites.Four non-white families were required to sell their land.  These types of provisions were mostly legally unenforceable afterShelley v. Kraemer (1948)though they continued to be added and privately unenforceable after theFair Housing Act of 1968(seeHousing discrimination in the United States).
In November 2021, following a two-and-a-half-month petition drive that achieved signatures from owners of 391 of the 534 properties in Ladera, the clause forbidding residency by people "other than those of the Caucasian or white race" was replaced by the statement: "By provisions outlined in this document the Ladera Community has formally acted to remove the Race Restriction that previously comprised this subsection, and by so doing asserts that the Ladera Community supports diversity, equity, and inclusion."
