FENCE RULES – CASS (COUNTY), NEBRASKA
OVERVIEW
Residential fences are permitted on private property within Cass County, subject to local regulations.
This page applies to properties in the unincorporated areas of Cass County; incorporated municipalities regulate fences under their own ordinances.
Cass County does not publish a single consolidated residential fence code. Fence-related rules appear across the Zoning Regulations of Cass County, Nebraska, including required-yard provisions, visibility definitions, floodplain overlay rules, design-guideline overlay standards, subdivision standards, easement rules, drainage standards, and the county’s adopted building-code framework.
Cass County lists the 2012 International Building Code and 2012 International Residential Code as adopted building codes. Those codes list fences not over 7 feet high as work exempt from building-permit requirements; because Cass County does not publish a separate local fence-permit rule, this page uses that adopted-code exemption as building-permit context.
This page focuses on typical single-family residential fencing, including rural residential and agricultural residential contexts where applicable. If the jurisdiction’s adopted materials do not state a specific limit or requirement, this page notes that the code does not specify one.
Compiled From the Cass County Planning & Zoning Department webpage, the Zoning Regulations of Cass County, Nebraska, the Cass County Subdivision Regulations, the Cass County Dept. of Zoning and Inspections Building Permit Application, the 2012 International Building Code, and the 2012 International Residential Code as of May 2026.
GOVERNANCE
Cass County residential fence rules are administered within the county’s zoning, building, floodplain, subdivision, and development-review framework.
• Governing Body: The Cass County Board of Commissioners is the county governing body for zoning and subdivision regulation.
• Planning Review: The Cass County Planning Commission reviews zoning and subdivision matters and makes recommendations where required by the zoning and subdivision regulations.
• Administration: The Cass County Dept. of Zoning and Inspections administers building permits, inspections, floodplain development permits, county road access permits, zoning changes, conditional use permits, platting, replatting, and related land-use changes.
• Board of Adjustment: The Cass County Board of Adjustment handles zoning appeals, interpretations, and variance matters under the zoning regulations.
• Adopted Building Codes: Cass County adopts the 2012 International Building Code and 2012 International Residential Code. Those adopted codes provide the building-permit exemption context for fences not over 7 feet high where no stricter local fence-permit rule is published.
• Fence-Code Structure: Cass County does not organize residential fence rules in one standalone fence ordinance. Fence rules appear in provisions governing required yards, visibility, floodplain development, overlay districts, subdivision design, easements, drainage, and private restrictions.
PERMIT AND APPROVAL REQUIREMENTS
• Building Code: Cass County adopts the 2012 International Building Code and 2012 International Residential Code. Both adopted codes list fences not over 7 feet high as work exempt from building-permit requirements. Cass County does not publish a stricter local fence-permit threshold in its zoning regulations, permit page, or building permit application.
• Permit Exemption Limits: The building-code permit exemption for fences not over 7 feet does not remove zoning, visibility, floodplain, easement, right-of-way, subdivision, or private-restriction requirements.
• Zoning Compliance: Building permit requirements are separate from zoning, setback, or plat requirements. Confirm any applicable zoning conditions, setbacks, and plat requirements with Cass County Dept. of Zoning and Inspections before construction.
• Floodplain Development Permit: A separate floodplain development permit is required before floodplain development in mapped flood hazard areas. Cass County’s floodplain obstruction definition includes a fence, so fences in mapped floodplain, flood fringe, or floodway areas are subject to floodplain review where the floodplain rules apply.
• Design Guidelines Overlay: In the Design Guidelines Overlay District, fences and walls used as landscape-plan, buffer, screening, or site-design elements must follow the overlay’s fence and wall standards where that overlay applies.
• Subdivision and Plat Context: Where a fence is part of subdivision development, platted easement areas, double-frontage arterial screening, or related development improvements, the Cass County Subdivision Regulations may affect placement, easements, drainage, and review context.
FENCE PLACEMENT RULES
• Required Yards: Cass County allows fences and walls in required yards, subject to applicable height restrictions.
• Property Lines: The ordinance does not state a setback requirement for standard residential fences from property lines; however, fences must be located entirely on the owner’s property and must not encroach into rights-of-way or easements.
• Rights-of-Way and Easements: Fence placement must not encroach into public rights-of-way, private rights-of-way, public easements, utility easements, drainage easements, or stormwater easements.
• Drainage: Fence work that changes land contours, obstructs drainage, interferes with drainage, or substantially changes drainage from the land to the detriment of neighboring land is subject to Cass County’s drainage standards.
• Subdivision Screen Easements: For subdivision double-frontage lots used in relation to an arterial street, Cass County requires a landscape screen easement of at least 10 feet along the line of lots abutting the arterial street. The subdivider must install trees, shrubbery, fences, or a combination to screen residential development from the arterial street and reduce traffic noise.
• Floodplain Placement: In mapped floodplain areas, a fence may be treated as an obstruction if it impedes, retards, or changes the direction of floodwater flow. Floodway and flood fringe placement must comply with Cass County’s floodplain standards.
• Utility Safety: Nebraska law requires notice through Nebraska 811 before excavation begins. For fence projects that involve digging, including fence post holes, notice generally must be given at least 2 full business days and not more than 10 business days before excavation begins, subject to limited exceptions.
FENCE HEIGHT AND VISIBILITY RULES
• Countywide Fence Height: The code does not specify a countywide zoning maximum height for standard residential fences.
• Adopted-Code Permit Exemption: Cass County’s adopted 2012 International Building Code and 2012 International Residential Code list fences not over 7 feet high as work exempt from building-permit requirements.
• Visual Obstruction: Cass County defines a visual obstruction as any fence, hedge, tree, shrub, wall, or structure exceeding 2 feet in height, measured from the crown of intersecting or intercepting streets, alleys, or driveways, when it limits the visibility of persons in motor vehicles on those streets, alleys, or driveways. Trees kept trimmed of branches below 8 feet are excluded from that definition.
• Clear View Zone: A clear view zone is the area of a corner lot closest to an intersection that must remain free of visual impairment so pedestrian and vehicle traffic can be fully seen.
• Sight Triangle: A sight triangle is an area at a street or road intersection where nothing may be erected, placed, painted, or allowed to grow in a manner that materially impedes traffic vision at the intersection.
• Agricultural and Transitional Agricultural Plantings: In the AG Agricultural and TA Transitional Agricultural districts, the zoning table separately lists tree and shrub setbacks. Deciduous trees and conifers must be set back 20 feet from County rights-of-way and rear or side property lines, and shrubs must be set back 8 feet from County rights-of-way and rear or side property lines.
MATERIAL AND CONSTRUCTION LIMITS
• Countywide Residential Materials: Outside specific overlay, landscape, buffer, screening, floodplain, or livestock contexts, the code does not specify countywide standard residential fence materials, opacity limits, finished-side orientation, or prohibited materials.
• Design Guidelines Overlay Materials: In the Design Guidelines Overlay District, fences or walls used as elements of a landscape plan must be constructed of wood, stone, brick, decorative concrete block, wrought iron, or products created to resemble those materials, as approved by the Planning Board.
• Finished Side in the Design Guidelines Overlay: In the Design Guidelines Overlay District, fencing must be finished on both sides. Fencing accessory to a residential use or development must be finished on all sides visible from off site.
• Screening and Buffering Materials: In the Design Guidelines Overlay District, plywood, particle board, sheet metal, concrete slabs, concrete barriers, or similar materials may not be used for fences or walls intended to provide screening or buffering.
• Chain-Link Fencing: In the Design Guidelines Overlay District, chain-link fencing may not be used for screening or buffering. Chain-link fencing may be allowed for security purposes as approved by the Planning Board, but slats are not allowed with chain-link fencing.
• Barbed Wire: In the Design Guidelines Overlay District, barbed wire and similar fence material may be used only in conjunction with the permitted keeping of horses or livestock.
• Opaque or Solid Fencing: In the Design Guidelines Overlay District, opaque or solid fencing that abuts a public road must be screened from the road. Where opaque or solid fencing continues for more than 40 feet of street frontage, at least 1 evergreen tree and 3 shrubs must be planted on the outer or public side of the fence for each 40 linear feet of fence.
• Landscape-Protection Fencing: In the Design Guidelines Overlay District, transparent fences, including very low-voltage electrified fencing, may be included around landscaped areas to protect landscaping from wildlife damage. Chain-link fencing is not allowed for that landscape-protection purpose.
• Pool Barriers: The code does not specify a separate local residential pool-barrier fence standard.
PRIVATE RESTRICTIONS
Private restrictions operate separately from Cass County zoning and subdivision rules.
• HOAs and Covenants: Homeowners association rules, subdivision covenants, deed restrictions, architectural-control rules, and private agreements may impose fence limits that are more restrictive than county standards.
• Private Easements: Utility easements, access easements, drainage easements, conservation easements, and private road agreements may limit where a fence can be placed, even when the zoning code does not state a property-line setback for standard residential fences.
• Subdivision Covenants: Cass County’s subdivision regulations require a final plat to include one copy of any private restrictions or covenants affecting the subdivision, if applicable. That filing context does not make every private restriction a county zoning rule unless an official county source states that the county administers that restriction.
• Rural and Agricultural Agreements: Boundary agreements, agricultural agreements, livestock-related arrangements, and private division-fence arrangements may affect rural or agricultural residential property independently of local zoning.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Adopted-Code Exemption: Fences not over 7 feet high are exempt from building-permit requirements under Cass County’s adopted 2012 International Building Code and 2012 International Residential Code, but that exemption does not remove other local zoning, floodplain, visibility, easement, right-of-way, subdivision, or private restrictions.
• Required Yards: Fences and walls located in required yards are reviewed against applicable height, visibility, and zoning conditions.
• Visibility Areas: Fences, hedges, trees, shrubs, walls, or structures over 2 feet in visibility-sensitive areas may be reviewed as visual obstructions if they limit motor-vehicle visibility at intersecting or intercepting streets, alleys, or driveways.
• Clear View and Sight Triangle Areas: Fences, walls, plants, or other objects in clear view zones or sight triangles may be reviewed where they materially impair pedestrian or traffic visibility.
• Rights-of-Way and Easements: Fences that encroach into rights-of-way, public easements, utility easements, drainage easements, or stormwater easements may be reviewed for placement compliance.
• Drainage Impacts: Fence work that obstructs, interferes with, or substantially changes drainage to the detriment of neighboring land may be reviewed under Cass County’s drainage standards.
• Floodplain Areas: Fences in mapped flood hazard areas may be reviewed under Cass County’s floodplain development and obstruction standards.
• Design Guidelines Overlay: Fences and walls used in applicable landscape, buffer, screening, or development-plan contexts within the Design Guidelines Overlay District may be reviewed for approved materials, finished-side treatment, chain-link limits, barbed-wire limits, opaque-fence screening, and maintenance.
• Subdivision Context: Fences used as part of required subdivision screening, double-frontage arterial buffers, easement areas, drainage facilities, or plat-related improvements may be reviewed through subdivision and development review.
