Firefighters shot streams of water from below and via a ladder truck above, at the scene located off Pontiac Trail and between Welch and Haggerty roads.
The cause of the fire was an electrical contract worker who hit a gas line causing it to ignite while he was performing work, according to a spokesperson from Consumers Energy.
There are no injuries reported. The entire complex has no gas service.
Firefighters were still at the scene after 10 p.m. putting out hot spots.
