The purpose of Chapter 19.40 SVMC is to provide alternative residential development options to traditional single-family dwellings and multifamily dwellings. These standards provide opportunities changing composition of households and the need for smaller, more diverse, and often, more affordable housing choices. Providing for a variety of housing types also encourages innovation and diversity in housing design and site development, while ensuring compatibility with surrounding single-family residential and nonresidential development.
