About 100 officials and athletes were briefly evacuated when the fire broke out in a car park rubbish bin.
It is believed the fire was caused by a cigarette. The Olympic Village is a non-smoking venue.
Chiller said the team received a certificate two days ago to say the building complied with fire standards.
"What we have subsequently found is that the fire alarms had been silenced while they were carrying out maintenance on the building next door to ours," she said.
