Bldg quality 2 poor

[Ccat]

I am looking at a Hawaii county listing on a house:

Bldg Quality: (2) Poor

Poor!  

What would “poor” consist of?  

Untreated wood, particleboard, poor quality nails or what? Is this below the (usually terrible) material quality and structural integrity of most stuff built in Puna?

Thanks,

Ccat
