In August, the county Board of Supervisors approved a $550,000 pilot program to build a handful of small backyard houses, or upgrade illegally converted garages, for homeowners who agree to host a homeless person or family. Then in February, Bloomberg Philanthropies awarded L.A. a $100,000 Mayor’s Challenge grant to study the feasibility of backyard homeless units within the city limits.

Rents under the county’s pilot program would be covered by low-income vouchers, with tenants contributing 30% of their incomes. The county is also sponsoring a design competition, streamlining permits and providing technical aid and financing options.

While the idea of backyard homeless units might seem far-fetched, officials hope it could be a fast and relatively inexpensive way to house the most stable individuals among the 58,000 homeless people in L.A. County.
