Typically less than 1,000 square feet and located in the backyard of main homes, accessory dwelling units (ADUs) are most often used for rental units or to house family members. Although legal and zoning regulations restrict their construction in many U.S. cities, a handful of jurisdictions—including Minneapolis and Portland, Ore.—are seen as ADU friendly, and advocates predict other areas soon will follow suit.
These five projects go beyond the traditional backyard flat with energy-efficient envelopes, full HVAC systems and appliances, high-end finishes, and clever storage solutions.
