Kapolei New Developments: What’s Being Built in West Oahu (2026)

Most of Oahu’s new housing is being built in Kapolei and on the Ewa plain, and there’s more on the way. Rail is running, Ho’opili is filling in, a new 2,500-unit community is starting between Kapolei Commons and Ko Olina, and Ko Olina’s old luau grounds are being rebuilt. Homes here still cost less than the Oahu median, which is the main reason buyers look west.

Here’s what’s actually under construction or approved as of October 2026, what’s still just a plan, and what it means if you’re thinking of buying.

Skyline rail: what’s open and what isn’t

The first segment of Honolulu’s Skyline rail opened on June 30, 2023. It runs just under 11 miles from East Kapolei to Aloha Stadium. Four of its stations serve West Oahu:

  • East Kapolei (Kualaka’i), the western end of the line
  • UH West Oahu (Keone’ae)
  • Ho’opili (Honouliuli)
  • West Loch (Ho’ae’ae)

Segment 2 opened on October 16, 2025. It added four stations, including one at the airport, and extended the line to the Middle Street transit center in Kalihi. Weekday ridership routinely topped 10,000 in the weeks after it opened.

Rail doesn’t reach downtown yet. Segment 3, from Kalihi to the Civic Center, is under construction and scheduled for 2031. The Kaka’ako and Ala Moana stations have been deferred with no date. So if you’re commuting from Kapolei to a downtown office, rail today gets you as far as Kalihi, and you’d connect by bus from there.

Permanent park-and-ride lots are still coming. As of September 2026, the city planned about 900 stalls at East Kapolei and about 1,100 at UH West Oahu, with bids expected around early 2027.

Ho’opili

Ho’opili is the biggest project out here. D.R. Horton broke ground in September 2016 on 1,554 acres of former farmland between Kapolei and Waipahu. At build-out it’s planned for 11,750 homes, about 3 million square feet of commercial space, five schools and 200 acres of farmland. Under its agreement with the city, 30 percent of the housing has to be affordable to low- and moderate-income local households.

It’s being built in phases over roughly 20 years, so it’s nowhere near done. The southwest sections are largely built and the project is pushing toward Farrington Highway. The first schools are still a few years out: as of late 2025, the plan was for an elementary school to open for enrollment by 2028–2029. Its own rail station, Ho’opili (Honouliuli), is a big part of the pitch.

Laulima, between Kapolei Commons and Ko Olina

Laulima is the next big master-planned community. It covers more than 500 acres running from Kapolei Commons toward Ko Olina, with about 2,500 homes planned. The developer is a partnership of Utah-based Wasatch Group and Hawaii-based Tower Development.

The first phase is 750 affordable rental apartments on about 24 acres west of Kapolei Commons, with completion expected by summer 2027. Most units are set aside for households at 60 to 120 percent of area median income. A shopping center, Laulima Gateway Center, is planned on 11.3 acres across the street, expected by 2028. Market-rate and luxury homes come in later phases.

Other housing on the Ewa plain

  • Kaulu by Gentry, Kalaeloa. 390 homes behind the Kapolei Costco, about halfway built as of late 2025. Single-family homes started in the low $900,000s and townhomes in the low $600,000s. Completion is expected in 2027.
  • Gentry in Ewa Villages. A smaller project of more than 130 detached single-family condos, with groundbreaking planned for the end of 2026.
  • Kauluokahai, East Kapolei. A Department of Hawaiian Home Lands community planned for 650 homes. These are for Native Hawaiian beneficiaries on the DHHL list, not the open market.

UH West Oahu

The University of Hawaii controls about 500 acres around the UH West Oahu campus, land donated by the former James Campbell Estate. UH plans to keep a large share for campus growth and has been trying for years to lease the rest for housing, retail and other uses to bring in income. A 2017 effort picked a development team for a 183-acre site east of campus along Kualaka’i Parkway. Progress has been slow, so treat anything you hear about a “university district” as a long-range plan until you see construction.

Ko Olina

The project that’s actually moving is the old Paradise Cove luau site next to Ko Olina. The luau closed at the end of 2025 after 47 years. A James Campbell Co.-led partnership is rebuilding the 10.85-acre oceanfront property as Waianiani at The Cove, with an amphitheater for nightly luau shows, three restaurants (including a Duke’s), a cultural pavilion and a small marketplace. A blessing was held in May 2026. It’s expected to open in the first quarter of 2028.

You may also see headlines about an Atlantis resort at Ko Olina. In January 2025 a California company, Kam Sang, bought the land next to Aulani for $216 million and revived plans for about 500 hotel rooms and 500 condos. That idea has been floated for close to 20 years. At the time, the local neighborhood board said it hadn’t received any proposals. Don’t buy nearby counting on it.

What homes cost out here

Oahu’s median single-family price was $1,110,000 in September 2026, and the condo median was $523,000. West side houses run below that. In the first quarter of 2026, the Ewa plain single-family median was $950,000 and Makakilo’s was $955,000, against $1,199,500 islandwide for the same quarter. Condos are a different story. Ewa plain condos ran about the same as the island median, around $533,500, because so many of them are newer townhome-style units.

So the discount out here is mostly on houses. You get more house and yard for the money than in town, and newer construction. What you pay for it is the drive. H-1 traffic from Kapolei into Honolulu is still the biggest complaint, and rail doesn’t fix that yet for anyone working downtown or in Waikiki.

What to check before you buy

  • What’s planned next door. A field today may be a school, a rail parking lot or a shopping center in five years. Look at the master plan for the area, not just the street.
  • Association fees. Most new communities here come with an HOA, and some have both a master association and a sub-association. Get the numbers early.
  • Affordable-unit restrictions. Some homes in Ho’opili and other projects were sold under affordable housing rules that limit resale price or who you can sell to. Make sure you know which kind you’re looking at.
  • Flood and tsunami maps. The Ewa plain is low and flat, and the areas closer to the coast, like Ewa Beach and Ko Olina, need a careful look. Check the specific address on the tsunami evacuation and FEMA flood maps.

FAQ

Can I take rail from Kapolei to downtown Honolulu? Not yet. As of October 2026 the line ends at Middle Street in Kalihi. The downtown extension is scheduled for 2031.

Is Ho’opili in Kapolei or Ewa? Both, sort of. It sits between Kapolei and Waipahu on the Ewa plain, and addresses vary by section. Search listings under both.

Is Kapolei cheaper than the rest of Oahu? For single-family homes, yes, usually by a couple hundred thousand dollars below the island median. Condo prices are close to the island median.

Is the Atlantis resort at Ko Olina being built? Not as far as public reporting shows. The land changed hands in 2025 and the plan was revived, but no construction has been reported.
