Wisconsin Does Not Require a Survey for Fence Construction
There is no Wisconsin state statute that requires you to obtain a land survey before building a fence. You can legally hire a fencing contractor and start building without ever having your property corners located by a licensed surveyor. But that decision comes with real legal and financial risk.
Wisconsin's fence laws under Chapter 90 of the Wisconsin Statutes and nuisance laws under Chapter 844 create consequences for fences built in the wrong location. A fence that encroaches onto a neighbor's property is a trespass. A fence built to intentionally annoy or obstruct a neighbor may be treated as a nuisance. Getting the line right before you build is significantly cheaper than dealing with these problems afterward.
Wisconsin's Partition Fence Law (Chapter 90)
Chapter 90 governs division fences in Wisconsin. The key provision is in Section 90.03, which applies to agricultural land. If both you and your neighbor use your land for farming or grazing, you are each legally required to maintain half of the shared boundary fence. The division is typically made by each owner maintaining the half on their right as they face the boundary from their property.
Section 90.10 provides a dispute resolution process. If neighbors cannot agree on the fence's condition, cost sharing, or location, either party can petition the town board to appoint fence viewers. The fence viewers inspect the fence, rule on who owes what, and their determination is legally binding. If the boundary itself is in dispute, the fence viewers may recommend a survey to resolve it.
When a Survey Is Practically Required
Even when the law does not technically require a survey, there are several situations where getting one before building a fence is the practical choice:
- You have not had the property corners located since you bought the land
- Original survey stakes are missing or have been moved
- Your lot has an irregular shape, curves, or angles
- Your neighbor has mentioned uncertainty about where the line is
- You are near the setback distance in your municipality's zoning code
- The fence will be permanent and expensive to move later
- Your deed description uses older metes and bounds language that is difficult to interpret without a surveyor
What a Corner-Staking Service Costs
Some Wisconsin surveyors offer a focused service where they locate and mark the existing corners of your property without producing a full boundary survey plat. This costs less than a full survey, typically $300 to $700 for a standard residential lot, because the surveyor does not always have to record a new plat with the Register of Deeds. Ask surveyors specifically whether they offer corner staking as a standalone service.
A full boundary survey with a recorded plat runs $450 to $1,500 for most Wisconsin residential lots and produces a map that you can rely on for future reference as well, including permits, sales, and disputes.
Check Local Zoning Before You Build
Wisconsin municipalities often set fence height limits and setback requirements. In many Wisconsin cities and towns, a fence must be set back a certain distance from the property line for the portion facing a street. Some communities also require a fence permit. Call your local zoning or building department before construction to confirm what is required. Placing a fence exactly on the property line may still violate a local setback rule.
Spite Fences and Nuisance Claims
Wisconsin Statutes Section 844.10 allows courts to order removal of a structure, including a fence, that is maintained for the sole purpose of annoying a neighbor and serves no useful purpose. If a fence clearly has no function other than blocking light, views, or access out of spite, a court may treat it as an actionable private nuisance. Building a fence on or very near the legal property line is legal and defensible. Building one designed purely to harm a neighbor is not.
