It is very easy
The information in the previous post is pretty accurate
However, you don't even really need Google maps
I mean you could do it that way
As stated in the post most counties have a parcel viewer. Thus for Ketron search "Pierce County Parcel Viewer"
Once you locate the Parcel Viewer you can use the interactive mapping
Also, once you find the parcel number the tax assessor usually has the most information on the property
