If you are house hunting in Central Oahu, two communities dominate the conversation: Mililani and Koa Ridge. Both offer family-friendly neighborhoods, good schools, and convenient locations between Honolulu and the North Shore. But they are very different in terms of age, design, pricing, and lifestyle.

This comparison breaks down the key differences to help you decide which community fits your needs in 2026.

Location and Access

Mililani has been established since the 1960s and sits along the H-2 freeway in the heart of Central Oahu. It includes Mililani Town and Mililani Mauka, both with easy access to Honolulu, Pearl Harbor, and the North Shore.

Koa Ridge is located directly adjacent to Mililani, between Mililani Town and Waipio. It sits across Ka Uka Boulevard from the Waipio Costco. The two communities share similar commute times and highway access.

Home Age and Construction

Mililani homes range from the 1960s to the early 2000s. Many homes have been renovated, but buyers should expect older construction, potential maintenance issues, and older building standards.

Koa Ridge is entirely new construction built to modern codes with energy-efficient features, smart home technology, solar water heating, and contemporary designs.

Pricing Comparison

Mililani single-family homes typically range from the $700Ks to over $1 million depending on size, location, and condition. Townhomes in Mililani generally start in the $500Ks.

Koa Ridge offers new construction starting from the $380s for Lau Le'a townhomes, with Nanea III single-family homes starting around $800K. Ke'olu offers income-qualified affordable options.

Community Design

Mililani was one of Hawaii's first master-planned communities with established recreation centers, pools, parks, shopping centers, and mature landscaping. It has a proven track record of stable home values.

Koa Ridge is designed as a surban community with the 7.5-mile Ho'ala Trail, walkable access to shopping and dining at The Gateway, a planned healthcare campus, elementary school, and Hale Lau Koa gathering space.

Schools

Mililani is served by established schools including Mililani High School, Mililani Middle School, and several elementary schools with strong reputations.

Koa Ridge will have a new public elementary school on 12 acres donated by Castle & Cooke. For middle and high school, Koa Ridge students will likely attend schools in the Mililani or Waipahu complex.
