Incorrect measurement of property lot in County records

[Allen Bo]

I started the remodel process with a GC of the property I own and the first thing they did was to measure the property lot.

It turned out that the county record has 6-ft less width for the lot than the actual length that measures on ground. So, they asked me to do the survey. I did my little research on the county website and I used their satellite based parcel map which allows to measure each lot. It turns out that the satellite parcel map measures what's on the ground. So, I got a bit curious to find out why the county records are incorrect. So, I measured all 4 lots width on my street and it turns out that two houses away neighbor has 6-ft less physical width than what the county records show. Note that we don't share any walls, there are two properties in between us and we both are the corner lots on the street.

So I called up the county and they insist that the county records are correct and they can only be changed with a new survey. 

What are my options here? Could the county or neighbor claim a piece of my land after the survey? Or has anyone dealt with this kind of situation where county records were incorrect and you were able to correct it. I have lived here for 6 years and all neighbors have proper fencing so there's no dispute otherwise. The two neighbors in between measures exactly same as their county records. Also, the county surveyor office mentioned that they have these records since the builder built the original buildings in 1979.

I'm also attaching the county parcel record that shows our property measurements.

Quote from @Allen Bo:

I agree that GIS does not trump deed record. But the problem seems to be when the original housing community was built. Even if we have to do a survey, the 6ft will go to the 2 neighbors away from me and they all of the properties will need to change the lot lines since the 2 lots between us don't gain/loose anything. And we will need to make every one resurvey their properties too, which seems unlikely.

I feel that i probably should cancel my addition plans since with the 6ft gone from my lot, I don't even know if my existing structure has the required set backs. It probably would be wise to sell the property. We really needed to do the addition for growing family needs. But with the situation above it would take months if not more to finish the legalities. Thoughts?

No one is going to be changing their lot lines….
Just get a survey of Your lot….then you’ll know what’s what, and how to proceed, or not. Until then, it’s just guessing.
