Eastside Heights Costa Mesa Homes For Sale

Coastal Living Meets Urban Convenience on the Newport Border

Eastside Heights: The Best of Both Cities

As a local resident in nearby Mesa Verde, I can tell you that Eastside Heights is where Costa Mesa's energy meets Newport Beach's prestige. Often compared to its neighbor across the city line, Newport Heights, this pocket offers a slightly more approachable entry point while delivering the same coastal breezes, tree-lined streets, and top-tier school access. The defining trend here is the Modern Rebuild: original 1950s bungalows being transformed into luxury vertical estates that maximize the lot with square footage, rooftop decks, and high-end finishes.
