Growth of the Backyard Bungalow

Accessory dwelling units are popping up in more backyards, CNBC reports. These standalone housing units are either serving as rentals to generate extra income for homeowners or extra space for aging parents or adult children who move back home. The growing interest in ADUs has sparked changes to local and state zoning rules to allow for more construction. Some communities are even pointing to ADUs as a solution for a lack of affordable housing.

“ADU is still, for the most part, an affluent homeowner product, meaning you have to have cash on hand to take this on,” Steve Vallejos, CEO of Prefab ADU, told CNBC. His company’s most popular ADU model is a 288-square-foot home that costs about $105,000 to build. ADUs are “addressing financing, it’s addressing standardizing products within cities, and then also it’s creating partner relationships with contractors, architects, and even other builders,” Vallejos says. “There are many different scenarios that people look into based on income, lot size, different zoning rules—so we build ADUs that start at about 150 square feet up to 1,200 square feet.”
