Zones where a residential care home for 7 or more people can go

What else applies
- RS and commercial rows cover 'small and large' together. 'Residential facility, small' is permitted in RM-3.5, RM-B/M/PA/P and DR. Blank cells for 'Residential facility, large' in S9 and S10 are not defined by the code as prohibited, so they are omitted.
- State law: A licensed care home for six or fewer residents is a residential use under state law (Health and Safety Code § 1566.3); this page covers larger homes.
- Not covered here: C-R (S12: planned unit development list only), C-F (S14: every use needs a CUP except public schools; § 20.55.025 prohibited uses not in packet) and U (S17: all uses need a CUP): no per-use cells used. Chapter 20.24 RM-3.5 prohibitions beyond the lists are not stated.. Overlay zones and specific plans can also change the answer.
