Overview — Detached Homes at Koa Ridge
Nanea III represents the third and final iteration of the beloved Nanea home series at Koa Ridge, Castle & Cooke Hawaii’s master-planned community in Waipio, Central Oahu. The name “Nanea” means “tranquil” in Hawaiian, and these homes deliver on that promise with published floor plans reaching 2,228 square feet.
What sets Nanea III apart from other neighborhoods at Koa Ridge is sheer size. While communities like Waioha II top out around 1,482 square feet and Walea II maxes at 1,557 square feet, Nanea III homes reach up to 2,228 square feet of living area — giving families the room they need without compromising on a new-construction experience.
These are detached single-family homes sold as condominiums under Hawaii’s condominium property regime (CPR). This means you own the home and the land beneath it fee simple, but share certain common areas and exterior maintenance responsibilities with the homeowners association. It’s a structure that keeps monthly costs manageable while delivering a true single-family living experience.
With 82 homes planned across Phase 1, three architectural styles to choose from (Hawaiian Plantation, Craftsman, and Contemporary), and a location within Koa Ridge’s walkable “surban” community, Nanea III is designed for buyers who want the best of both worlds: suburban space with urban convenience.

Frequently Asked Questions
What does “detached single-family condominium” mean?
It means the home is a standalone, detached house — not attached to any neighbor. However, it’s legally structured as a condominium under Hawaii’s CPR (Condominium Property Regime). You own the home and land fee simple, but common areas and exterior maintenance are managed by the HOA.
What are the monthly HOA fees?
Budget for the master association and the separate condominium assessment. Koa Ridge’s 2026 master base assessment is quoted at $239.34 per quarter ($79.78 per month equivalent) in the Puaola public report.
Nanea III Phase II: $66.76 per month in condominium maintenance estimates. 2025 budget basis. Source: DPR effective May 2, 2025. The master assessment is additional.
Confirm the current statement for your exact unit and when owner billing begins. A newer report can still use an older budget basis; these published estimates are not a verified current owner bill. See the full association-fee guide for the dated comparison and documents to request.
Can I customize my Nanea III home?
Customization depends on the specific home and construction stage. With no homes shown available on the builder’s October 1 detailed price page, first confirm an actual opportunity before choosing upgrades.
Is Nanea III fee simple or leasehold?
Fee simple. You own the home and the land beneath it outright.
How far is Koa Ridge from Honolulu?
About 20 miles from downtown Honolulu. The commute is 30–40 minutes outside peak hours and can stretch to 50+ minutes during rush hour via H-2 and H-1.
Are there schools nearby?
Koa Ridge is zoned for Waipio Elementary, Highlands Intermediate, and Mililani High School. A new elementary school is also planned within the community.
Is Nanea III a good investment?
New construction in Hawaii has historically held value well due to limited land supply. With only 82 homes and Nanea III being the final Nanea installment, scarcity could support long-term appreciation. That said, CPR resale can be more complex than traditional single-family resale.
Bottom Line
Nanea III may suit buyers seeking detached condominium homes and larger published layouts. Confirm current new-home or resale availability and compare the exact property’s price, fees and condition before deciding.
