HOUSING: A New Start-Up Wants to Build a Tiny House in Your Backyard For Free. “Bay Area start-up Rent the Backyard is making new room in dense cities by collaborating with homeowners who’ve got a little extra acreage. The company will install a prefab studio apartment on unused land behind your home, handle all the permitting required to do so, find a worthy tenant to rent the unit, and pay you 50% of the profits for providing the space—all for zero up-front costs.”
