Homeowners in unincorporated communities who qualify can receive up to $75,000 to build a second dwelling in areas zoned for such structures, while others may get $50,000 to update and legalize an existing dwelling.
The program was introduced last year as part of Los Angeles County's set of 47 strategies to solve homelessness. The office of Regional Planning will work with several departments countywide with an allocated $550,000 in part to be used to offer subsidies.
Unlike a guest house, second dwellings include kitchens.
The program also will streamline the permitting process and provide technical assistance to homeowners within the county's unincorporated areas, who would qualify, officials said.
Details of who would be housed and the selection process are still under discussion, said supervising regional planner Connie Chung on Monday. Funding allows for two to three new second dwellings, and for the remodeling of two to three existing ones, she added.
