Research notes
County counterpart to §519.21. Applies to unincorporated territory only; does NOT apply to municipal corporations. Same structural carve-outs: platted subdivisions & 15-contiguous-lots rule, 1–5 acre lot regulation, marijuana exclusion. federal_conflict_check flagged for same CMH Part 77 / AICUZ reasons.
