A note here on Sunlight Holding Co. This community certain has the aspects and feel of cohousing, but there was no movement around it yet, it didn’t declare itself to be cohousing. It was built before the term “cohousing” had been introduced by Katie and Chuck’s book, was not broadly publicized and Portland’s hidden secret. Muir Commons in Davis, California is thought to be the first officially declared cohousing community built in North America, in 1991.
