Watch-outs
- Sunny Hills zoning vs. not is a major price split — confirm the boundary
- Troy uses lottery/exam admission — district residency alone doesn't guarantee entry
- West/central Fullerton has higher school variance
FJUHSD core lineup
- Sunny Hills High School: #1 Korean-family target. 25+ AP courses, very high Korean share. Zoned for East Fullerton (Raymond Hills, parts of Yorba Linda).
- Troy High School: STEM and IB programs, very high Korean/Chinese student share — entry-by-application is more competitive than the district itself.
- La Habra High School: more accessible entry, average school.
Why Sunny Hills zoning costs more
Inside Fullerton, Sunny Hills zoning vs. not is a major price differentiator. Sunny Hills-zoned SFR runs $1.2M–$1.5M; outside the zone the same footprint drops to $700K–$1.0M. Always confirm the boundary before submitting an offer.
Korean infrastructure
Beach Blvd and Magnolia Ave form OC's densest Korean retail corridor. Galleria Korean Plaza, H-Mart Buena Park, and Zion Market La Habra are all within a 10-minute drive. Korean academies are also well-represented.
