A fire destroyed a garage and damaged one half of a duplex Saturday night in Stokes Court in east Petaluma.

The residents of 203 Stokes Court were not home when the fire broke out, said Capt. Kevin Weaver Petaluma Fire Department.

No one was injured, but a pet died in the fire. Smoke damaged the other unit in the duplex, at 201 Stokes Court, and the residents there evacuated safely.

Officials estimated the fire damage at $150,000. The cause of the fire is still under investigation.
