If you've been researching new construction on Oahu's West Side, you've likely come across Ka'ulu by Gentry — the 390-home master-planned community taking shape in Kalaeloa. Whether you're a first-time buyer exploring reserved housing options, a military family stationed nearby, or a move-up buyer looking at single-family homes, this guide covers what you need to know about Ka'ulu as of early 2026.

What Is Ka'ulu by Gentry?

Ka'ulu is a roughly 30-acre community built by Gentry Homes, one of Hawaii's most established kama'aina homebuilders with over 14,000 homes built statewide. Located in Kalaeloa — the former Naval Air Station Barbers Point — the community sits behind Kapolei Costco off Franklin D. Roosevelt Avenue. The name Ka'ulu was inspired by the ulu (breadfruit) tree, chosen with the guidance of local kupuna.

The development includes 390 total homes at full buildout: 262 townhomes and 128 single-family detached homes. Homes feature plantation and craftsman-style architecture with varied exterior color schemes. The project is being built in 8 increments with approximately 49 sales phases and is roughly halfway complete as of early 2026, with full buildout expected by 2027. Ka'ulu is part of the broader Kalaeloa Community Development District overseen by HCDA (Hawaii Community Development Authority).

Home Types and Floor Plans

Ka'ulu offers two main home types: single-family detached residences and townhomes in 6-plex and 8-plex configurations. All homes include 9-foot ceilings, central air conditioning, fiber-optic wiring, solar water heating, and EV-ready garages.

Single-Family Homes (3 plans, all 3 bed / 2.5 bath with enclosed 2-car garages): Aukai (1,508 sq ft, from ~$920,000+), Makali'i (1,592 sq ft, from ~$948,000+), and Hoku (1,581 sq ft, from ~$948,000+). These are market-priced homes with plantation and craftsman-style exteriors.

Townhomes (5 plans, in 6-plex and 8-plex buildings): Waipuna (2 bed/2 bath, 1,020 sq ft), Lokahi (3 bed/2 bath, 1,080 sq ft), Makani (3 bed/2 bath, 1,194 sq ft), Kainalu (2 bed/2 bath, 877 sq ft), and Wiliwili (2 bed/2.5 bath, 1,324 sq ft). Townhomes range from the low $600,000s for reserved housing units to the mid-$700,000s for market units. Check current availability and pricing.

How the Purchase Process Works

New homes at Ka'ulu are released in phases via a lottery system, followed by first-come-first-served availability. Each release is announced publicly with a sales packet pickup date. Buyers must sign an owner-occupant affidavit and submit a $1,000 deposit within 48 hours of home selection. For reserved housing units, HCDA guidelines apply — including income limits (up to 140% AMI) and asset restrictions. Reserved housing features an attractive 5-year regulated period, shorter than the 10-year standard at most other projects.

Resale homes are also becoming available on MLS as early owners sell. These follow the standard Hawaii purchase contract process, and buyers can work with their own agent.

Why Having Your Own Buyer's Agent Matters in Ka'ulu

Buyers purchasing new construction in Ka'ulu can — and should — bring their own buyer's agent. Having independent representation means someone is reviewing the purchase agreement, advising on the process, and advocating solely for your interests. The builder's sales team represents the builder. For resale Ka'ulu homes on MLS, an experienced agent familiar with the community's floor plans, association rules, and pricing trends adds real value to the buying experience.

Is Ka'ulu Right for You?

Ka'ulu is one of several strong options on Oahu's West Side. It appeals to buyers seeking brand-new construction at accessible price points, especially those who value energy-efficient features, VA-approved financing, and proximity to beaches and military installations. That said, it's worth comparing Ka'ulu against Ho'opili, Ewa Beach, Kapolei, and even Central Oahu communities like Mililani to find the best fit for your family and budget. We help buyers explore all options across the island.
