Go to your county's website and find the GIS (geographic information system) link. Many counties have your property lines mapped and you can see them overlaid on maps.You may be able to see your property and the state/county right of ways. There is a lot of information that is public record that you can find by doing some research.
Great idea. Check the county website
I had a 48x36 pole barn/garage built...a neighbor who (lives across street) didn't want it to be built because it would block the scenic view of nearby woods would surely have waited for me to build and then raise hell (another great idea IF you are right about lot lines). I used the County GIS 'parcel viewer' to verify the property lines. A county employee told the builder that the lines shown on the viewer are accurate to within 2 feet. Didn't hurt that the next door neighbor was the local property tax collector. She knew the property lines very well.
