How to Resolve Encroaching Structures and Retaining Wall Disputes in Wisconsin

Discovering that a neighbor's newly built structure crosses your property line can be incredibly frustrating. Whether it is a poorly measured privacy fence, an expanded concrete driveway, or a massive retaining wall altering the drainage of your yard, encroaching structures directly violate your property rights. If left unchallenged for too long in Wisconsin, your neighbor might legally secure the right to keep the structure there permanently through adverse possession or a prescriptive easement.

Resolving boundary disputes over physical structures requires a blend of diplomacy, accurate surveying, and, when necessary, firm legal action.

Legal Options for Encroaching Structures in Wisconsin

Wisconsin law provides property owners with several remedies when facing a physical encroachment. The best option depends on the size of the encroachment, the cost of removing it, and your relationship with your neighbor.

Negotiating Lot Line Adjustments

If a neighbor accidentally built a garage six inches onto your property, forcing them to tear it down may be economically unreasonable and cause intense neighborhood friction. Instead, you can negotiate a lot line adjustment. This involves legally redrawing the property boundaries and selling that small strip of land to your neighbor. The new boundary must be surveyed, approved by local zoning authorities, and recorded with the county register of deeds.

Granting a Revocable License

If a neighbor's retaining wall or garden shed is on your land and you do not want to sell the land, but you also do not want to force them to tear it down immediately, you can grant them a written, revocable license. This legal document gives them explicit permission to keep the structure there temporarily. Because they have your permission, their presence is no longer 'hostile', meaning they can never claim adverse possession. You retain the right to revoke this license at any time, such as when you decide to sell your home.

Drafting and Recording a Boundary Agreement

A boundary agreement is a formal contract between neighbors that acknowledges an encroachment exists but dictates how it will be handled. For example, the agreement might state that the neighbor's fence can remain until it falls into disrepair, at which point any replacement must be built on the correct property line. This agreement should be drafted by a lawyer and recorded with the county to ensure it binds future owners.

Suing for Removal vs. Monetary Damages

Under Wis. Stat. § 844.01, any person claiming an interest in real property may bring an action to address physical injury to, or interference with, that property. In Wisconsin courts, plaintiffs generally seek one of two remedies. The first is an injunction (or ejectment), where the judge orders the neighbor to physically remove the structure at their own expense. The second is monetary damages, where the judge allows the structure to stay but forces the neighbor to financially compensate you for the loss of land value. Wisconsin courts balance the equities; if a retaining wall encroachment is minor but costs $30,000 to demolish, the court may award damages rather than forcing removal, as seen in cases similar to Soma v. Zurawski, 321 Wis. 2d 91 (WI Court of Appeals 2009).

Step-by-Step Process in Wisconsin

If you suspect an encroachment, follow these steps to protect your investment.

Step 1: Hire a Licensed Surveyor

Before making demands, you must have undeniable proof. Hire a surveyor licensed by the Wisconsin Department of Safety and Professional Services, Madison to stake the property lines. Old fences and landscaping do not legally define property boundaries; only a certified survey matched against the recorded deed does.

Step 2: Attempt Mediation or Out-of-Court Settlement

Share the survey results with your neighbor in writing. Offer practical solutions, such as a timeline for them to move the shed or an offer to grant a revocable license. If communication breaks down, consider hiring a neutral third-party mediator to help find a solution before spending thousands on litigation.

Step 3: File a Lawsuit for Ejectment or Injunction

If the neighbor is uncooperative, you must file a lawsuit to stop the clock on adverse possession. You will initiate the action in the Civil Division of your local Circuit Court, such as the Racine County Circuit Court, Racine or the La Crosse County Circuit Court, La Crosse. Your attorney will submit a summons and complaint pursuant to Wis. Stat. § 801.02 through the Wisconsin circuit court eFiling system, selecting the appropriate civil classification to petition the court for an order of removal.

How Much Does it Cost in Wisconsin?

Fighting an encroaching structure requires financial investment. Typical costs include:

• Certified Survey: Depending on the lot size and complexity, expect to pay between $600 and $2,000 for a boundary survey.
• Court Filing Fees: Initiating a civil lawsuit in Wisconsin typically costs $164.50.
• Legal Fees: Property lawyers in Wisconsin usually charge between $250 and $450 per hour. Drafting a boundary agreement might cost $1,000 to $1,500, while a full trial to force removal can exceed $15,000.

How Long Does the Process Take?

If both neighbors are agreeable, a lot line adjustment or boundary agreement can be finalized and recorded within 4 to 8 weeks. However, if you are forced to file a lawsuit in a Wisconsin Circuit Court to secure an injunction, the process of discovery, pre-trial motions, and waiting for a court date can easily extend the timeline to 12 to 24 months.
