A Springfield state office building damaged by a small fire appears ready to be back in business after a one-day closure.

Secretary of State's Office spokesman Dave Druker says the Howlett Building was closed to business Tuesday after a fire occurred about 1:15 a.m. that day in a mechanical room.

The building is part of the Illinois State Capitol complex.

Druker says firefighters quickly put out the blaze, but the air conditioning in the building wasn't working and crews needed to work on mechanical issues.

The building houses between 750 and 1,000 employees of the secretary of state's office and is frequently visited by members of the public. Among the services, motorists can purchase license plates and vehicle stickers there.

Druker says the building was expected to reopen Wednesday.
