Honolulu Mayor Rick Blangiardi and city leaders stood in Waikīkī on Friday morning to watch something the neighborhood hasn't seen before: remotely operated demolition robots tearing into the vacant former Ena Motoi building. The specialized machines are being used to dismantle the eight-story structure at 436 Ena Road, clearing the way for what the city says will become a large affordable housing development in the heart of Waikīkī.
The demonstration marked a public debut for the technology, which city leaders framed as part of a broader modernization push, according to Hawaii News Now. Blangiardi called the use of robotics “really incredible” and said it represented another step toward modernizing the city and moving it into the current era, per the station's report. The robots allow crews to take down the structure without putting workers directly inside the aging building during the most labor-intensive phases of demolition.
A Building With A Long History As Housing of Last Resort
The site has a layered past. The property was the first city-developed project in Waikīkī to accept Housing First vouchers, offering 33 studio apartments starting in April 2018, according to Honolulu Civil Beat. The city operated the building as affordable rental housing until 2023, when the 12 remaining tenants had to move out after officials determined the repairs needed to keep it livable were too extensive, Civil Beat reported.
The 6,000-square-foot parcel sits just off Kalākaua Avenue and includes the now-empty eight-story building along with a detached parking structure, Aloha State Daily notes. The city selected EAH Housing as its preferred negotiating partner for the site's redevelopment in July 2025, with Guam-based Core Tech serving as co-developer and Lowney Architecture handling design work, according to the same outlet's earlier coverage.
Demolition Timeline And Site Safety
Full demolition of the Ena Road building was expected to begin the week of Oct. 26 and run through the end of February 2027, Aloha State Daily reported. The site is set to remain secured with safety fencing throughout all phases of the work, with crews operating during standard construction hours, per the outlet's account. The city had previously described itself as preparing to begin the demolition as part of its broader push to redevelop underused, city-owned parcels into housing.
Part Of A Larger Citywide Push
The Ena Road site is one of four underutilized, city-owned properties — alongside 1615 Ala Wai Boulevard, 130 South Beretania Street and 1421 Pensacola Street — that Honolulu's Department of Land Management identified for affordable rental redevelopment, according to Aloha State Daily's reporting. The city's Department of Land Management issued a request for qualifications in February 2025 seeking developers for those four properties, per a statement from the Office of the Mayor, City and County of Honolulu. Partnering with developers to build on city land is one component of the city's broader strategic housing plan, the outlet notes.
Other projects in that pipeline illustrate the scale the city is aiming for. Demolition at the former Dee Lite Bakery site in Kalihi was nearing completion, with preliminary estimates suggesting that property could accommodate approximately 150 affordable rental units, according to Aloha State Daily. Separately, the city's Waikiki Vista purchase, made for $37.75 million, is expected to eventually provide 100 affordable units, Civil Beat reported.
Why Robots, Why Now
Construction robots can handle repetitive and labor-intensive tasks with greater speed and precision than human crews, potentially boosting productivity while reducing musculoskeletal injuries, according to a CDC/NIOSH Science Bulletin. For a dense, high-rise-heavy neighborhood like Waikīkī, that kind of precision matters — taking down an eight-story structure near a busy commercial corridor comes with little room for error.
For now, the Ena Road site remains fenced off and under demolition, with the robots doing work that would once have required a different kind of crew altogether. What eventually rises there — and exactly how many units it will hold — has not yet been finalized publicly, but the city's intent is clear: another vacant, city-owned property in Waikīkī is being cleared to make room for affordable housing.
