The Tomah Fire Department reports flames 20-feet high were blowing through the roof of a series of downtown buildings when crews arrived on the scene just before 5:00 a-m Sunday.
Firefighters from several communities joined in the effort to knock down the flames and rescue residents in the apartments above.
Two businesses, Dimensions Bar and the Artisan Market were destroyed.
One apartment resident was taken to Tomah Health for evaluation.
Firefighters say he was hanging out of a second-floor window when they rescued him.
The cause of the damaging fire is still being investigated.
