Authorities are continuing to investigate a fire that closed down a downtown hotel over the weekend. No injuries were reported when a fire started in a maid’s closet at the Ramada Hotel, 205 W. Fourth St., at 9:27 a.m. Sunday.

Smoke triggered a sprinkler in the closet, and water flowed all the way to the lobby, said Battalion Chief Marty Freshwater with Waterloo Fire Rescue. He said there also was smoke on other floors, and the smell could be detected on the ground floor.

Ramada was evacuated and remained closed for Sunday to allow for repairs and cleanup, Freshwater said. The cause hasn’t been determined, but investigators have ruled out electrical reasons and traditional causes.

Flames damaged boxes of paperwork that were stored in the closet but didn’t spread outside the room. Freshwater said the door and sprinkler kept the fire in check but didn’t put it out. Firefighters extinguished the blaze.

At the time of the hotel fire, crews were busy fighting a garage fire, Freshwater said. A neighbor called in the garage fire at 621 Peek St. at about 8:53 a.m. Sunday.

The fire gutted the double-stall detached garage. No vehicles were inside, but heat damaged a Chevrolet Corvette parked next to it. The garage was a total loss, and the cause is under investigation. The garage was fitted with a wood burning stove, Freshwater said.
