Summary
Boundary-fence disputes in Waukesha County are governed by Wisconsin's partition-fence law, not the county. On adjoining farm or grazing land, both owners must build and maintain the line fence in equal shares. For residential lots, cost-sharing is usually a private matter unless a town fence viewer is involved.
The respective occupants of adjoining lands used and occupied for farming or grazing purposes... shall keep and maintain partition fences between their own and the adjoining premises in equal shares.
Full Breakdown
Wisconsin Statutes chapter 90 sets the framework for line (partition) fences. Under Wis. Stat. 90.03, occupants of adjoining lands used for farming or grazing must keep and maintain the partition fence between their premises in equal shares. Town fence viewers can be asked to determine each owner's obligation and apportion cost. A "legal fence" for these purposes must be at least 50 inches high with the bottom no more than 4 inches off the ground (Wis. Stat. 90.02). Waukesha County itself sets no residential shared-fence rule; strictly residential disputes typically turn on the deed, survey, and private agreement.
Violations & Fines
If an owner fails to maintain a required partition fence, town fence viewers may order repairs and the complying neighbor can recover double the cost under Wis. Stat. ch. 90.
