I've been researching the history of the Laurelhurst neighborhood in Portland for my upcoming book.  Here's a piece of the original deed restriction when the addition was platted in 1909:

"... nor shall the same or any part thereof be in any manner used or occupied by Chinese, Japanese, or negroes, except that persons of said races may be employed as servants by residents; nor shall any old buildings be placed on said premises; nor shall any building or any part thereof, on said premises, be erected, maintained, or used for flats, apartments, stables, stores, or business or manufacturing Purposes; nor shall any intoxicating liquor be manufactured, or sold or otherwise disposed of as a beverage in any place of public resort, on said premises."

This is not quaint or ancient.  It was just yesterday.  If you are over fifty, this is the world in which your grandparents grew up.
