I’m on the consultant side so don’t know all the inner workings. I would guess not and that it’s a matter of manpower to process them all. I mostly see boundaries adjusted when parcels are split or right of way is acquired. Looking at the project I have up now, GIS boundaries of some right of way that was acquired within the last 10 years is within 3” of what our survey shows. Right of way that was established in the 50s varies in accuracy, could be dead on or it could be 5’ offset. Skimming through the property boundaries most are pretty close but might be a few feet off. Probably a third have at least one boundary that is 10+ feet from where our survey says it should be including several from a development that was split in the 90s.

GIS parcel boundaries are absolutely not precise enough for something like this.
