Neighborhoods that work well offer a variety of housing types.  As our housing needs change over time, this variety provides us the opportunity to remain in the same community.  Single-family houses of various sizes as well as garage apartments, duplexes, and multi-family dwellings should be located near each other so younger and older people, singles and families, people with disabilities, those of limited means and the wealthy may find places to live together.  It’s also important to make sure these different types fit together by using design principles such as appropriate setbacks, scale, and similar architectural elements so they look like they belong together.  Now let’s look at housing choices.
