Best Fit
Pros
- Official county website provides the current county source path for local government follow-up
- prior ordinance index indicated land-use and subdivision rule sources need county confirmation
Cons
- Current ordinance index path is brittle and needs manual confirmation
- Remote parcels may have service access water and road constraints

Alternative Housing Notes
Tiny Homes
Union County needs deeper county-office source review before tiny home assumptions are finalized. The current county site provides the first official contact and local government source path for land-use follow-up.
RV Living
RV living should be confirmed with county officials because the ordinance index does not establish blanket long term RV occupancy rights.
Off Grid
Off grid projects should verify land use ordinance subdivision ordinance water septic access roads state building requirements and fire response before relying on rural acreage.
Container Homes
Container homes should be reviewed with county and state building resources before relying on a parcel.
ADUs
ADU feasibility should be checked against county ordinances utilities municipality boundaries and subdivision restrictions.
