Linn County, IA Fence Regulations: Height Limits (2026)

Linn County regulates fences through Chapter 107 - Unified Development Code - which contains the General Regulations (Article V) covering accessory features such as walls and fences. Specific maximum heights vary by zone district (A, AG, RR, R, C, I, etc.), by yard (front, side, rear, corner-lot street side), and by whether the fence is solid or open. Sight-distance triangles at intersections and driveways further limit fence height regardless of zone. Building permits are required when a fence is structural, exceeds the height threshold set by the adopted International Residential Code, or is part of a pool enclosure. Iowa Code Chapter 359A, the partition-fence law, applies to lawful fences between adjoining rural landowners (typically agricultural land used for livestock) and provides a process for fence viewers to apportion construction and maintenance costs. Iowa has no statewide 'spite fence' statute - disputes over a malicious fence between neighbors are civil matters. Cities inside Linn County (Cedar Rapids, Marion, Hiawatha, Robins, Fairfax, Mount Vernon, Lisbon, Center Point, Walker, Springville, Coggon, Ely, Bertram, Palo, Alburnett, Central City) each adopt their own fence height rules in their zoning codes - typically lower in front yards and taller (often six feet) in side and rear yards - that supersede county rules within corporate limits.
