I cannot speak about California, but I do know that Florida had such restrictions until the mid/late 1950’s. Jews could not rent a hotel room North of 41st Street in Miami Beach, and Jews could not buy or own real estate in Coral Gables until the late '50’s.
These caveats were fairly common in other parts of the country back then.
Today when people talk about civil rights, they think in terms of blacks and latinos. Well, they are Johnny come lately when it comes to predjudice! The immigration laws of the US are all based on racial and religious prejudice. The first such laws were enacted in the 1890’s to exclude asians, particularly Chinese and Japanese, to protect the US from the “Yellow Peril”. The next group of laws in the 1920’s excluded Eastern and Southern Europeans, in order to protect the US from Jews and Catholics. In fact, the prohibition laws that banned liquor was enacted to make the US unpopular for Catholics to immigrate to! That is how it was actually argued for in the Congress!
