The blaze started at the rear of the building and was quickly brought under control, but cleanup will take some time, according to owners.
The Fire Marshal has determined the fire was caused by an electrical issue.
There were no other injuries reported in the blaze, which broke out around 3:00 PM.
The call for service came in just after 4:00 PM Wednesday as severe thunderstorms moved through the West End.
The fire broke out around 12:30 PM Tuesday and spread to a total of eight units.
