What became Standard Pacific Homes started in California in 1965. At one time Standard Pacific was America's 11th largest home builder.
In 2015, they merged with Ryland Homes to create CalAtlantic Homes which resulted in creating the nations 4th largest residential home builder. The Standard Pacific Name was dropped as a brand name and all future construction was branded under the CalAtlantic name.
In 2018, Lennar Homes merged with CalAtlantic Homes to create the nation's largest home builder (at the time). The CalAtlantic name survived as a brand name and wholly owned subsidiary of Lennar Homes.
