Sweet Home Police arrested Matthew Allen Pitts, 29, for first-degree arson Monday morning.
Sweet Home firefighters responded to a report of a fire at 1530 Tamarack St., space 16, at 3:45 a.m.
Police heard the dispatch on the radio and responded to assist, said Police Chief Jeff Lynn. Smoke was coming out of the residence, and police found evidence that it was an arson.
Pitts was inside the residence, which belongs to a relative, Lynn said. Another adult was sleeping inside.
Pitts was transported to Linn County Jail.
The investigation is continuing, Lynn said, but he does not anticipate additional charges.
