Buying Land in Buffalo County, Wisconsin

Zoning: countywide, except two towns that opted out

Buffalo County's Zoning Department administers a general zoning ordinance covering unincorporated land throughout most of the county, applicable only where the underlying town has approved it -- the standard Wisconsin mechanism. In Buffalo County's case, the county's own zoning-ordinance documentation identifies the Towns of Montana and Waumandee specifically as not zoned under the county ordinance, meaning those two towns are either unzoned or covered by their own separate arrangement rather than the county's Title/zoning code. Critically, the county's documentation is explicit that this carve-out is limited to general zoning -- shoreland, floodplain, and sanitary (POWTS) rules administered by the county remain in effect in Montana and Waumandee regardless of the general-zoning opt-out.

For any other town in the county, Buffalo County zoning (revised most recently in 2018, building on an earlier 2016 ordinance) governs land use, with the usual agricultural, residential, and other districts. Confirm the applicable zoning district and its permitted uses directly with the Zoning Department for a specific parcel -- staff have field responsibilities, so calling ahead or scheduling an appointment is recommended rather than a walk-in visit.

The Mississippi River: a Corps-managed pool, and a federal wildlife refuge, not just scenery

Buffalo County's western border runs along the Mississippi River for roughly its whole length, but the river here is not a naturally free-flowing waterway -- it's part of the federally managed 9-foot navigation channel system, held in place by a series of locks and dams. Lock and Dam No. 4, built in 1935 and operated by the US Army Corps of Engineers' St. Paul District, sits directly at Alma, the county seat, and creates Pool 4 (roughly 878,000 acre-feet of capacity) stretching upstream to Lock and Dam No. 3 near Hager City. Water levels along this stretch of river frontage are maintained for barge navigation rather than set by natural seasonal flow, which affects how backwater sloughs, islands, and bottomland behave here compared to an unregulated river.

A substantial share of the river-adjacent land in the county also falls within the Upper Mississippi River National Wildlife and Fish Refuge, a 240,000-acre, 261-mile refuge running from Wabasha, Minnesota to Rock Island, Illinois, and the smaller Trempealeau National Wildlife Refuge (about 6,808 acres) extends into the county's extreme southern edge. Refuge land is federally owned and not available for private purchase, and private land near or bordering it can be subject to conservation-easement or land-protection-program interest from the US Fish and Wildlife Service. See our dedicated page on flood zones and river dynamics in this county for what to check on a specific parcel near the river.

Bluff terrain, agriculture, and the Driftless landscape

Buffalo County sits entirely within the Driftless Area, the region of the Upper Midwest that escaped the most recent glaciation and as a result has a much more rugged, deeply carved landscape than most of Wisconsin -- steep, wooded bluffs, narrow coulees, and river-bottom flats rather than the flatter till-plain terrain found elsewhere in the state. Agriculture dominates land use here, accounting for roughly 70% of the county's total acreage, primarily dairy operations alongside corn and soybean cultivation; the county supported 896 farms as of the 2022 Census of Agriculture. For anyone evaluating a larger parcel for farming or homesteading, the terrain itself -- not just zoning or soil class -- often dictates how much of a given parcel is realistically farmable or buildable.

Septic, GIS, and agricultural resources

Buffalo County's Land Management Department (Courthouse, 4th Floor, 407 S. 2nd St, Alma) handles sanitary (POWTS) permit applications alongside zoning and land-use permits, and accepts digital sanitary-permit submissions by email; a Wisconsin Certified Soil Tester is the required first step for siting a new system. The county's GIS/Land Information Office maintains parcel mapping, and the Register of Deeds (same courthouse address) holds recorded deeds and easements. As in the rest of Wisconsin, there is no county assessor's office -- confirm assessed value with the specific town or municipality rather than a county office.

For agricultural land, UW-Madison Division of Extension's Buffalo County office (Courthouse, Room 1210, Alma; 608-685-6256) provides agricultural guidance for the county's substantial dairy and row-crop sector.
