For the second time already this week, Rockford Fire battles a vacant house fire.
On Tuesday afternoon, an empty apartment building in the 500 block of 15th Street caught fire. It sustained heavy smoke damage. The building was next door to a vacant business, which did not sustain much damage.
No one was hurt.
Authorities are looking for the owners of both buildings, which have laid empty for awhile.
There are no damage estimates at this time.
