Research notes

Statewide floor for grandfathering lawful pre-existing uses on zoning changes. Substantive floor (not a ceiling) — cities retain wide discretion on amortization, substitution, and expansion terms. Counterpart statutes: §519.19 (townships), §303.19 (counties). Applies to NON-CHARTER municipalities; charter cities are governed by their charter's grandfather provisions.
