A rooftop restaurant fire evacuated about six businesses Wednesday afternoon on North Academy Boulevard.

Colorado Springs firefighters responded to Nacos Tacos at 233 N. Academy Blvd. shortly after 3 p.m. after receiving multiple calls about a fire at the restaurant. Flames were visible when the first crew arrived on scene, and a second alarm was issued.

The fire was in a heating, ventilating and air conditioning unit on the roof of Nacos Tacos.

No one was injured in the blaze, which was contained to the taco shop and did not spread to adjacent businesses. Everyone evacuated from other businesses in the structure and people were told they could not return until firefighters deemed them safe.

The cause of the fire was under investigation Wednesday afternoon, said Capt. Steve Oswald, a spokesman for the department. Construction had been going on in part of the restaurant, Oswald said.

One of the businesses evacuated was FadeAwayz Barbershop, but that didn’t stop barber Wayne Ingram from doing his work.

He grabbed a case with clippers in it as he ran out the door with customers, and trimmed a man’s goatee from the trunk of a car while they waited for the building to be cleared.
