Built in 1924 as the home for the SF Lighthouse for the Blind, a local SF organization that was founded in 1902 and still exists to promote the independence, equality, and self-reliance of people who are blind or have low vision.  From their website:

As the Association grew, the need to expand facilities emerged. In 1924, three members of the Cowell family stepped forward with the generous offer to buy land and construct the building that would house the Association’s expanding services. With the support of Isabel, Helen and S.H. Cowell, the Association moved to a new facility at 1097 Howard Street later that year. For the next two decades, the Association continued manufacturing and selling brooms, baskets and furniture produced by blind workers, and began teaching braille, instructing white cane technique and providing counseling. This made the organization quite unusual. In the 20^th century blind people doing any kind of work was unheard of, and the industrial opportunities the LightHouse provided 100 years ago were considered the most progressive options then available.
