In Wisconsin, property deeds define legal boundaries that directly impact backyard fence placement, ensuring structures stay on your land to avoid disputes. State laws under Chapter 90 emphasize partition fences between adjoining properties used for farming or grazing, while local zoning dictates setbacks, heights, and permits. Missteps can lead to neighbor conflicts, removal orders, or liability for encroachment.​
Boundary Basics
Deeds recorded with the county register outline exact lot lines, often via surveys; always verify yours before building to confirm fence location. Fences on or over the line may require neighbor agreements, especially partition fences meeting state specs (e.g., 50 inches high woven wire). If a fence predates a survey and sits on adjacent land, the builder owns it but must relocate within 30 days of notice.​
Fence Rules
State law mandates “legal fences” for agricultural use but leaves residential details to local ordinances—typically 4-6 feet max height in backyards, with setbacks of 0-3 feet from side/rear lines. Closer placement needs written neighbor consent, recorded with the register of deeds to bind future owners. Permits often required for lengths over 20 feet or heights above 4.5 feet; check your town or city hall.​
Resolving Disputes
Town fence viewers can divide shared fence responsibilities and set timelines if neighbors disagree. Encroachment violations allow affected owners to demand removal or sue for damages; agreements should be notarized and filed. Consult a surveyor or local zoning office early to align with your deed and avoid costly fixes.​
