Summary
Olmsted County requires a zoning certificate before anyone builds, alters, converts, enlarges or occupies a building or premises in the unincorporated county. The Zoning Administrator issues it only after confirming the work conforms to the zoning ordinance, and nonconforming alterations must be specifically flagged on the certificate.
It shall be unlawful to use, occupy or permit the use or occupancy of any building or premises or part thereof, hereafter, created, erected, changed, converted, altered, or enlarged in its use or structure until a zoning certificate shall have been issued by the Zoning Administrator stating that the use of the building or land conforms to the requirements of this ordinance. Where a non conforming use or structure is extended or substantially altered, the zoning certificate shall specifically state the manner in which the non conforming structure or use differs from the provisions of this ordinance.
Full Breakdown
06 of the Olmsted County Zoning Ordinance makes it unlawful to use, occupy, or permit the use or occupancy of any building or premises, or part of one, that has been created, erected, changed, converted, altered or enlarged in use or structure, until the Zoning Administrator has issued a zoning certificate stating the use conforms to the ordinance. 04, the zoning ordinance's jurisdiction 'shall apply to all the area of Olmsted County outside the incorporated limits of municipalities,' so cities like Rochester, Stewartville, Byron, Eyota, Oronoco and Pine Island issue their own permits and this section does not reach them.
04 places the compliance duty directly on property owners, architects, contractors, subcontractors and builders, requiring them to confirm before starting any work that it does not conflict with the ordinance. 06 requires the zoning certificate to state specifically how the structure or use differs from the ordinance's standards, so the Zoning Administrator can track the extent of the nonconformity going forward. 00 and may designate Rochester-Olmsted Planning Department staff to act on these permits. 02, the Zoning Administrator's duties include issuing zoning certificates and other required permits, inspecting buildings and land for compliance, and maintaining permanent records of certificates, amendments, conditional uses and variances.
Certain activities, including construction of a dam or an on-site septic system and repair of a flood-, fire- or tornado-damaged structure, require a permit from the Zoning Administrator verifying compliance with the floodplain regulations before work begins, separate from the general zoning certificate.
Violations & Fines
Section 3.10 makes any person, firm, corporation or entity that violates the zoning ordinance, including building or occupying without a required zoning certificate, guilty of a misdemeanor. Each day the violation continues is a separate offense. Paying a fine does not excuse the offender from still complying with the ordinance, and the County Board or Zoning Administrator can pursue additional actions or proceedings, including seeking injunctions or corrective orders, under Section 3.08.
