Crews responded to the building located in the 800 block of S. Hobart Boulevard shortly after 8 p.m. Tuesday.
LAFD says the 40-year-old woman was located about 20 feet down from the roof.
Crews used a rope system from the roof to securely attach a harness to the woman and lower her down to the ground, according to officials.
LAFD says the woman had no signs of any injuries when firefighter paramedics inspected her at the scene.
It was not known how the woman ended up in the trash chute.
No further details were immediately available.
