Fire code compliance for SB 1211 ADUs
The one local power that survives ministerial review.
Fire-code compliance is the one local power that fully survives SB 1211 ministerial review. Local fire marshals can require: (a) adequate fire-apparatus access, (b) sprinklers in some configurations, (c) fire-rated separation between ADUs and existing structures.
Cities cannot use fire code as a pretext for de-facto denial — the standards must be the city's standard fire code applied uniformly — but the costs add up. Budget $5K–$25K per project for fire-code compliance work.
