Does your neighbor have an unpermitted home in their backyard? It’s more likely than you think, and it may be filling a valuable niche in the housing market. Vinit Mukhija of the UCLA Dept. of Urban Planning joins us to talk about his new book, Remaking the American Dream, and how informal and incremental housing is reshaping single-family neighborhoods. This is part one of a two-part series; in part two we’ll get into the weeds on accessory dwelling units (aka backyard cottages, granny flats, etc.) and debate the merits of state intervention in local housing policy.
