How this ordinance defines it
The operative definition is the local one. Codes routinely subdivide a category into tiers — “day care 2, family”, “group home 2” — and attach different permissions to each, so only La Mesa’s own text settles what this covers.
No passage in this ordinance names it directly
The use appears in this jurisdiction’s district tables, but a search of the chapters read so far turned up no sentence defining it. It may be defined in a chapter not yet retrieved, or under a different wording.
