Ele lives at a nearby senior apartment complex, and asked that her last name not be used to protect her identity.
She says activity increased after the Pearl Harbor Bike path was swept in August.
Over the past few months, Ele said, squatters have been found making themselves at home inside their community room and laundry facility. Clothes and electric scooters have been reported missing. At times, she doesn't feel safe.
"They sit around. They sat by my door until I asked them where are you going. They said, 'oh I'm going to see my grandma.' I said what's your grandma's apartment number? They said, 'oh never mind' and they just walked out," said Ele.
Scott Morishige, the governor's homeless coordinator, said he wasn't aware of the encampment and has since notified outreach workers about the situation.
"We're going to be in coordination with the city and county to see what we can do in terms of a coordinated response," Morishige said.
