Investigators are working to determine what sparked a fire this afternoon inside a detached outbuilding on property just outside the Tacoma city limits.
They were also looking into what appeared to be a marijuana grow operation that was found inside the small building, Central Pierce Fire & Rescue Assistant Chief Randy Stephens said. A Pierce County sheriff’s deputy found paperwork authorizing the small grow operation and was looking into its legitimacy.
A neighbor spotted smoke coming from the building and called Central Pierce firefighters about 12:45 p.m.
Crews were dispatched to the 9900 block of Patterson Street South and attacked the flames inside the building.
The fire was contained to the outbuilding. No one was inside at the time and no injuries were reported.
Stephens said the fire was possibly sparked by an electrical issue.
