The Town of Erin is a rural town in southwestern Washington County known for its rolling Kettle Moraine hills, farmland and scenic country roads. Homes are primarily single-family on acreage, including hobby farms and horse properties, and the Erin Hills championship golf course is located here.
Acreage and agricultural properties bring their own questions — outbuildings, land use, wells and septic — which we’ll address early in the plan.
