Summary
Olmsted County regulates fences in unincorporated areas through its Chapter 1400 Zoning Ordinance, administered by the Olmsted County Planning Department for the cooperatively-planned townships of Eyota, Marion, Oronoco, and Quincy. Privacy fences in residential districts are generally limited to 6 feet, with corner-lot sight-distance rules restricting front-yard fence height to preserve traffic visibility. Fences may sit on the property line if both sides can be maintained, but not within road or utility easements. Olmsted County is comprised of 18 townships and eight cities that may administer their own zoning. For permits and questions, contact the Olmsted County Planning Department at 507-328-7100.
Section 10.32 FENCES, WALLS AND HEDGES: Fences, walls and hedges may be located in any required yard or buildable lot area, subject to the provisions of Section 10.18; but shall not exceed six (6) feet in height above the elevation of the surface of the ground at any point, except that in instances where public safety or security necessitate, the Zoning Administrator may authorize fences and walls to have a maximum height of not to exceed ten (10) feet above the elevation of the surface of the ground at any point.
Full Breakdown
Olmsted County's Chapter 1400 Zoning Ordinance is the controlling document for fence regulation in unincorporated areas the county directly administers, and for the four townships under cooperative planning with the county (Eyota, Marion, Oronoco, Quincy). The ordinance treats fences as accessory structures: residential fences are typically capped at 6 feet in side and rear yards, with shorter limits in front yards and within sight-distance triangles at corner lots and driveway approaches to maintain traffic visibility. Fences may be placed on the lot line provided the owner can maintain both sides; placement within drainage, utility, or road easements is prohibited.
Building setbacks along county, state, and federal roads are 95 feet from the road centerline; township roads use 78 feet from centerline - these setbacks govern accessory structures and screening fences along rights-of-way. There is no statewide Minnesota fence-height cap; counties operate under Minn. Stat. Ch. 394 (county zoning authority). The remaining 14 townships in Olmsted County administer their own zoning under township authority, and the eight cities (Rochester, Stewartville, Byron, Pine Island, Chatfield, Dover, Eyota, Oronoco) each apply their own zoning code within municipal limits, which generally supersedes county rules. Always confirm the regulating authority for a specific parcel with the Olmsted County Planning Department before building.
Violations & Fines
Building a fence that violates Chapter 1400 (excessive height, encroachment into easement or sight triangle, placement within road setback) can result in a stop-work order and zoning enforcement action by the Olmsted County Planning Department. Owners may need to apply for a variance through the Zoning Board of Adjustment, lower the fence, or remove it to come into compliance. Disputes between adjoining neighbors over a boundary fence are civil matters not enforced by the county.
