№ 02 — Questions
West LA ADU questions, answered.
Does SB-9 actually work in West LA?
Yes on many R1 lots, but the 1,200 sf minimum split parcel and 5-yr owner-occupancy affidavit screen out flips. We pre-screen feasibility in week 1.
Garage conversion or detached?
Conversion is faster (4–6 wk plan-check) but caps at the existing footprint; detached unlocks 1,000 sf and higher rent.
What's the impact-fee bill?
Westside ADUs under 750 sf pay $0 in DWP/sewer connection fees; above 750 sf, expect $6K–$10K.
