HENRIETTA, N.Y. — The cause of a three-alarm fire at a former hotel in the town of Henrietta Sunday morning remains undetermined.

Firefighters say a passing deputy spotted smoke coming from the Country Inn and Suites building on West Henrietta Road near the intersection of Lehigh Station Road around 4 a.m. and called it in.

More than 100 firefighters were called to the scene from 13 fire departments. According to the fire district, 30 percent of the building was on fire when they arrived. It took them five hours and more than 1 million gallons of water to put out the flames.   

“It collapsed within five minutes of arriving on scene,” said Henrietta Assistant Fire Chief Mark Cholach.

Officials say the former hotel was undergoing construction, with plans to turn it into an assisted living facility. Firefighters say the fire alarm and sprinklers were shut off at the time due to the renovations.

"Those sprinklers, if they were there, I'm sure that fire would have been a couple thousand dollar loss, now we're talking a $10 million loss, said Henrietta Fire Chief Mark Stryzynski. “I think the value of sprinklers has to be understood. If you're building a house, spend the extra money and put a sprinkler in your house. From a life safety perspective, sprinklers save lives.” 

No one was inside at the time of the fire, however they say the hotel next door was fully booked at the time.

"The Fairfield, which is full occupancy, was unaffected. It's just to the south of the building on fire. It's full because of a hockey tournament in town, it was unaffected and we didn't have to move anybody," said Lt. Jared Guhl, Henrietta Fire Department.

Firefighters say the building partially collapsed. There are no reports of injuries.

When asked why the adjacent properties weren't evacuated — with seven houses and a 500 pound propane tank in vicinity — officials say the fire was contained enough to keep the flames away.
