The fire burning in Old town Fort Collins is now officially "under control" and there is an estimated 24+ residents displaced and at least one business destroyed.

The Red Cross has set up a service center to assist firefighters and residents at 220 N. Howes Street.

Anyone wishing to help is invited to contact United Way 211 regarding donations.

A fire that destroyed the under-construction Old Town condo building, Mason Street Flats, and severely damaged the adjacent Penny Flats building has been brought under control, although there's still a pall of smoke hanging over Fort Collins.The three-alarm fire was reported about 3:30 a.m. Monday, and Penny Flats residents raced from their building at 204 Maple St. as the unfinished building north of them went up. More than 60 firefighters from Poudre Fire Authority and Loveland Fire-Rescue found the blaze.

"There's a huge amount of damage," said PFA spokesman Capt. Patrick Love.

The fire's cause remains under investigation. Love said it's too early to say exactly how much damage was caused, or how long it may be before residents can return to their condos. Love said no one was hurt in the fire.

PFA is asking the residents avoid the area of downtown Fort Collins bordered by Cherry St. on the north, LaPorte Ave. on the south, Mason St. on the east, and Howes St. on the west.

The City of Fort Collins tweeted that Downtown Transit Center is closed due to the fire and that all DTC routes will instead arrive and depart on College Ave. south of Maple Street.
