A fire at an abandoned house caused about $50,000 in damage early Tuesday.

Fire crews were called to 3900 S. 945 East about 1:20 a.m. They arrived to find a fire burning on the second floor, said Unified Fire Authority Capt. Wade Russell.

No injuries were reported. The cause of the fire was still being investigated, but Russell noted the sheriff's office had been having problems recently with transients.
