No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Branch County and how hard.
The score describes unincorporated county land only. Inside Branch County, incorporated municipalities set their own, usually stricter, rules — including: City of Coldwater — own zoning, City of Bronson, Village of Quincy, Village of Sherwood, Village of Union City, Zoned townships whose ordinances are more stringent than the state code take precedence. Land inside town limits follows town code.
