The fire began in the area of Mountain Avenue and McPherson Road.
Footage from AIR7HD showed the blaze spreading to a farm with two covered greenhouses growing marijuana plants. It's unclear if it was a legal or illegal grow.

Firefighters reported containing the forward spread of the flames. By 8:30 p.m., the blaze was 80 percent contained, fire officials said.
No injuries were reported.
