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.

What is Eastside Heights in Costa Mesa?

The neighborhood sits within easy walking distance of the 17th Street Corridor and is zoned for Kaiser Elementary and Newport Harbor High School, making it consistently one of the most in-demand addresses in Costa Mesa.

How is Eastside Heights different from Newport Heights?

Eastside Heights is in Costa Mesa and Newport Heights is in Newport Beach, though they share a border and are often compared. Newport Heights typically commands a premium due to the Newport Beach city designation and closer bay proximity.

Most Eastside Heights addresses are served by Kaiser Elementary and Newport Harbor High School, both within the Newport-Mesa Unified School District. Kaiser Elementary is an award-winning campus that draws significant buyer demand to the neighborhood. School boundaries can change, so buyers should always verify the current boundary for a specific address directly with the district before making a purchase decision based on school assignment.

What types of homes are for sale in Eastside Heights Costa Mesa?

Eastside Heights has a mix of original mid-century ranch homes and newer luxury infill construction. The original homes tend to be single-story with good lot sizes that attract buyers looking for renovation projects or ADU potential. The newer builds are typically multi-level custom estates or detached townhome-style homes that maximize the lot with vertical square footage.
