MILWAUKEE (CBS 58) -- No one was hurt when a vacant house caught on fire on Milwaukee's northside this evening.

It started around 4 p.m. at a two-story house near Clarke and Teutonia.

Investigators are unsure where in the house the fire started but had to use a larger amount of water than usual to put the fire out.

"It was about 3000 gallons of water times about 120 minutes so that's quite a bit of water. Our crews did a phenomenal job, they stayed very aggressive but they did their job very smartly and aggressively safe. I appreciate that, and we were lucky we did not have an exposure problem. There were vacant lots on both sides of this fire building so everything went very well," said Deputy Chief David Votsis with the Milwaukee Fire Department.

The house is owned by the City of Milwaukee and the fire caused an estimated $250,000 in damage.
