San Francisco is not known for detached houses with landscaped setbacks, lining picturesque, park-side streets. But between 1905 and 1924, thirty-six such neighborhoods, called residence parks, were proposed or built in the city. Hundreds like them were constructed across the country yet they are not well known or understood today. This book examines the city planning aspects of residence parks in a new way, with tracing how developers went about the business of building them, on different sites and for different markets, and how they kept out black and Asian residents.
