The owner of a two-story warehouse that caught fire Sunday night and revealed a marijuana grow inside says he was operating a collective co-op, Tacoma police said.
A passerby called 911 about 10:22 p.m. after noticing smoke coming from the warehouse in the 2500 block of Jefferson Street.
After fire crews extinguished the blaze, they found evidence of a marijuana grow so they called police.
About 600 pot plants, ranging from seedlings to mature plants, were found inside the warehouse, police spokeswoman Loretta Cool said.
Also found inside were chemicals, grow lights and other equipment and pot in baggies.
The alarm company called the warehouse owner to alert him to the situation and he called his attorney before responding to the scene, Cool said.
Police have not yet determined whether he is licensed to grow marijuana.
Investigators determined the fire was caused by an electrical overload.
