Across the San Fernando Valley, public records show 25,423 ADU permits in the 33 cities and neighborhoods listed below. The most active are North Hollywood (Los Angeles) (1,960), Glendale (1,733) and Burbank (1,520).
Where the numbers come from
Counts come from the California Department of Housing and Community Development's annual progress reports, which every city files with the state, and, for City of Los Angeles neighborhoods, from Department of Building and Safety permits. Each area's page shows its yearly counts and, where the source publishes them, permit times, ADU types and declared costs.
