Ten American Accessory Dwelling Units Highlight Design Solutions for Housing Crisis

A survey of ten accessory dwelling units (ADUs) throughout the United States showcases a range of architectural styles influenced by evolving regulations. California's 2016 legislation permits ADUs between 200 and 1,500 square feet. States such as Arizona, Kansas, Texas, Hawaii, and Maine are also beginning to embrace ADUs, although the implementation can be slow. In New York City, Mayor Zohran Mamdani introduced a WXY-designed initiative aimed at streamlining ADU development. Among the highlighted projects are ByBen's Offset ADU in Los Angeles, a concrete block design by Benjamin Hall in Arizona, Specht Novak's Stealth House in Austin, and Cover Architecture's Moongate ADU in California. Additional remarkable designs feature Mork-Ulnes Architects' Crest Guesthouse, 3R Studio's Evelyn ADU, Kendle Design Collaborative's Flex Pavilion, Schwartz and Architecture's Diamond ADU, North Arrow Studio's Birdhouse ADU, and Studio 804's 722 Ash Street.
