Building a Multigenerational ADU in Sun Valley

- Lot sizes commonly 6,500–10,000 sq ft — plenty of room for a rear-yard ADU.
- Under LA's transit-oriented rules most Sun Valley parcels are exempt from added parking.
- Older detached garages convert cheaply ($120K–$180K) when the slab is sound.
Zoning note: LADBS reviews Sun Valley ADU permits under the same 60-day statewide clock. Watch flood-zone flags along the Tujunga Wash.
