You’re right!! Chino Hills is on the LA county border. Hard to tell (if you miss the little freeway county border signs) because the area is built up and one community blends into another. San Bernardino county border makes an unusual jog west and includes Chino Hills. Interestingly CH ends up west (and south) of Pomona which is in LA!
The close proximity of CH to LA area is the reason these properties are selling and prices are high.
