It sounds sort of resolved, but unfortunately simply issuing house numbers is a pragmatic act for safety reasons not associated with legally subdividing the land. The county officials do not understand their position function.
"The county officials do not understand their position function."
It's all about zoning. This states constitution does not give power to zone to the county commission. The county commission wants that power and were using the issuance of house numbers as a means of defacto zoning. If they didn't want you to build in an area, then they would simply refuse the house number. An ammendment to the constitution to give zoning power to this county's commission was soundly defeated a couple of years ago.
