Geography first
Pick your region.
San Francisco, South Bay, East Bay, North Bay, Sacramento, or the rest of Northern California. Once you pick, every chapter can stay scoped to that geography.
Region hubs
Start with where you actually are.
Every region hub rolls up local Chabad contacts and the chapters most likely to matter nearby.
San Francisco
The city itself — peninsula to the Bay.
South Bay
Palo Alto, Mountain View, Santa Clara, Sunnyvale, San Jose, Los Altos.
East Bay
Berkeley, Oakland, Lafayette, Walnut Creek, Pleasanton, San Ramon.
North Bay
San Rafael, Marin, Napa, Sonoma, Vacaville, Solano.
Sacramento Area
Sacramento, Roseville, Davis, Grass Valley.
Other NorCal
Tahoe, Chico, Humboldt, Central Valley (Fresno, Modesto, Stockton), Monterey, Santa Cruz.
The directory is intentionally region-first. A mikvah in Vacaville is not functionally useful if you are in Palo Alto on a Thursday afternoon. A rabbi in Berkeley may be exactly who you need if your daughter is at Cal and nowhere near your home community.
These region pages make that geographical layer shareable, indexable, and stable. You can now send someone directly to the South Bay kosher page or the Sacramento region hub instead of telling them to set a local filter first.
