Full Breakdown

Violations & Fines
A home or accessory building built taller than its district allows is a Zoning Ordinance violation under Section 21050.05, a misdemeanor fined up to Minnesota's maximum misdemeanor level with each day over height counted separately. The Zoning Administrator can halt construction and order a structure brought into compliance under Section 21050.03, and an existing over-height structure predating the Chapter is handled instead under the non-conforming buildings rules in Section 21100.
