Do I Need a Survey to Build a Fence in Wisconsin?

Key takeaway

Wisconsin does not require a survey to build a fence, but fence law under Chapter 90 and boundary disputes make one worth getting first.

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.

Frequently Asked Questions

Does Wisconsin require a survey before building a fence?

No state law in Wisconsin requires a property survey before building a fence. However, Wisconsin's Chapter 90 fence statutes and Chapter 844 nuisance law create legal exposure if you build a fence in the wrong location. Getting a survey protects you from building on a neighbor's land or being forced to move the fence later.

What is Wisconsin's partition fence law?

Under Wisconsin Statutes Section 90.03, owners of adjoining land that is used for farming or grazing must each maintain half of the shared boundary fence. Each owner is responsible for the half on their right as they face the boundary from their side. If one owner fails to maintain their half, the other may do the work and recover the cost.

What happens if I build a fence on my neighbor's property in Wisconsin?

Building a fence on a neighbor's land without permission is a trespass. The neighbor can require you to remove it at your expense. If the encroachment is small and goes unchallenged for 20 years, adverse possession law could become relevant, but that is a last resort remedy. A survey before building is much cheaper than a fence removal and legal dispute after.

How do I find a surveyor to mark my property line before building a fence in Wisconsin?

Search our Wisconsin land surveyor directory to find licensed surveyors in your county. When contacting them, explain that you need property corners marked before fence installation. Many surveyors offer a corner-staking service that is less expensive than a full boundary survey.

Can I use my county's GIS parcel map to locate my fence line?

No. County GIS parcel maps are approximate displays, not legal surveys. The parcel boundaries shown are derived from deed descriptions and are not field-verified. Using a GIS map to place a fence can put you several feet off the actual legal boundary. Only a licensed surveyor can establish the legal location of your property line.
