L.A. fire crews responded to the scene on Holland Avenue on Monday.
The house caved under the weight of the machinery, which appeared to be a telescopic forklift. The roof of the residence was seen with significant damage.
A neighbor said no one was home at the time, and no one was hurt.
It's not clear why the forklift tipped over.
Correction: A previous version of this story described the machinery as a crane. This has since been corrected.
