What this means
Counts are permits issued, not completed homes; some of these projects are still under construction and some will never break ground. The counts cover the City of LA portion of zip 91352, so anything outside city limits is not included. The busiest full year so far was 2025, with 148 ADU permits issued; the 2026 count runs through July only.
