UPDATE: Four units have been destroyed by the fire, leaving six to eight people displaced. Firefighter have not confirmed the number of renters.
A neighbor witnessed the fire and says he could feel the the warmth of the flames halfway from the fire.
"I''ve seen fires before but at a great distance, I've never seen one start and build up as much as this one did," Randy Moguel-Sanchez, said.
It's everyone's worst nightmare. Luckily no one was home during the fire.
"I was sitting at home watching a movie and I glanced out the window and we saw a ball of fire on the balcony," Moguel-Sanchez said. "We ran outside, I called 9-1-1. The fire department responded within five minutes."
By the time the firefighters arrived, the fire had spread to the apartment next door and then to the bottom two units, two units were unoccupied.
"There's a significant amount of damage which is hard to figure out where exactly it started," Carson City Fire Department Assistant Chief, Tom Tarulli said. "We'll have to pinpoint that location.
"It's weird how there was a fire right next door to mine pretty much and it was scary too," Moguel-Sanchez said.
Fortunately, no occupants or firefighters were injured, but two dogs and a cat did not survive. It's a fire that investigators suspect started outside.
"There's exterior wooden decks which are kind of nice for evening picnics so there's a good example of why we say we don't want people to barbecue on their patios or decks," Tarulli said. "We're not sure of how the fire started, but there's a good reason why we don't allow that."
Currently, the cause of the fire is still under investigation.
CARSON CITY, Nev. -- Firefighters in Carson City are mopping up after a large fire at an apartment complex on W. College Parkway.
