If a property has a construction rating associated with it, it is a number coming from the county assessor's office. You should be able to find the definition on their website.
Here's a link to a thread where the one for King County, Washington is explained (Zillow is in King County). I suspect the definition varies from county to county.

How is the Zillow Construction Rating determined?
