New billboards statewide moratorium establishment and existing billboards nonconforming uses declaration provision

SF 485 establishes a statewide moratorium on new billboards in Minnesota, prohibiting state agencies and local governments from issuing permits for any new signage after the law takes effect. Existing billboards are declared "nonconforming uses," meaning they can remain but cannot be replaced or expanded under standard zoning rules. The bill amends Minnesota Statutes to prevent municipalities from using "amortization" (gradual phase-outs) to eliminate existing billboards, while preserving the moratorium. This directly affects billboard owners, local permitting authorities, and communities concerned with roadside aesthetics and tourism.
