Buying Land in Manitowoc County, Wisconsin

Zoning: county-administered in most towns, town-administered in two

The Manitowoc County Planning and Zoning Department (4319 Expo Drive, Manitowoc, WI 54221; 920-683-4185) administers the county's General Zoning Ordinance, codified as Chapter 8 of the county code and comprehensively revised effective November 7, 2011. That ordinance covers 16 of the county's 18 towns -- Cato, Centerville, Cooperstown, Eaton, Gibson, Kossuth, Liberty, Manitowoc, Manitowoc Rapids, Maple Grove, Meeme, Mishicot, Rockland, Schleswig, Two Creeks, and Two Rivers -- with districts spanning agricultural, residential, commercial, and industrial classifications plus conditional-use and variance procedures handled through the county's Planning and Zoning office.

The Towns of Franklin and Newton are the exceptions: each administers its own separate zoning ordinance rather than being covered by the county's. Franklin adopted a town-specific "Unified Development Ordinance" (most recently amended May 19, 2025), which -- because Franklin sits inside an already-zoned county and is exercising village-power zoning authority under Wis. Stat. 60.62(3) -- still requires Manitowoc County Board review and approval of amendments, even though the ordinance itself is Franklin's own, not the county's Chapter 8. Newton separately administers its own "Zoning and Land Division Ordinance" (amended in 2025). If a parcel sits in either town, the town's own office -- not the county Planning and Zoning Department -- is the right first call for zoning questions.

Shoreland zoning: the layer that follows the water, not the town line

Manitowoc County's Chapter 9 Shoreland Zoning Ordinance (last updated as of 2022-02-15) implements the statewide NR 115 minimum standards within 1,000 feet of the ordinary high-water mark of Lake Michigan or an inland lake, pond, or flowage, and within 300 feet of a river or stream -- including filling/grading restrictions and a vegetative buffer zone requiring a zoning permit for most vegetation-management activity within that band. Because Wisconsin law doesn't let a town withdraw from county shoreland zoning the way it can opt out of general zoning, Chapter 9 applies the same way in Franklin and Newton as it does in the 16 county-zoned towns. Given the county's 25-plus miles of direct Lake Michigan frontage plus its inland lakes, ponds, and streams, this is worth checking on any parcel that's near water at all, not just ones that look waterfront on a map.

Karst geology, private wells, and the county's livestock-siting ordinance

Manitowoc County sits within the same Silurian-dolomite karst belt that runs through Kewaunee, Door, Brown, and Calumet counties in northeast Wisconsin -- a region where soils over the bedrock are often thin and the rock itself is fractured enough that surface contaminants, particularly livestock manure, can reach the groundwater aquifer far faster than in areas with thicker soil cover. A joint five-county study across this region (Brown, Calumet, Door, Kewaunee, and Manitowoc) found that roughly 14% of 7,521 private-well samples exceeded a federal health advisory level, underscoring that this is a documented, ongoing regional issue rather than a rare edge case.

Manitowoc's own regulatory response to that vulnerability is its Chapter 28 livestock facility siting ordinance, administered by the county's Soil and Water Conservation Department, which has required farms expanding past 750 animal units to obtain a county license since 2007 -- a rule locally credited with cutting manure-related spill complaints roughly in half. One specific term of that license, a five-year manure-spreading-agreement requirement between the farm and land where manure would be spread, was ended by county executive order in May 2026 after debate over whether it was too burdensome for landowners. See our dedicated page on this for what it means for anyone buying land near an existing or proposed livestock operation, or relying on a private well, in the county.

Septic, subdivision, and where to check parcel records

Onsite wastewater (POWTS) permitting is handled through the Sanitary division of the Planning and Zoning Department (same 4319 Expo Drive address, 920-683-4185), which issues sanitary permits and administers the county's POWTS maintenance-tracking program under the statewide SPS 383 code. Land division outside the incorporated cities and villages runs under Chapter 12 of the county code (Subdivision Regulations, last updated 2022-02-15), which requires a certified survey map for most divisions and routes larger subdivisions through the Planning and Park Commission consistent with Wis. Stat. ch. 236.

The Manitowoc County Register of Deeds (1010 South 8th Street, Manitowoc; 920-683-4010) and Treasurer (same address; 920-683-4021) handle recorded documents and the tax roll, while GIS parcel mapping is published through the county's own online portal at manitowocmaps.info. Extension Manitowoc County offers agricultural and land-use programming relevant to the county's working farm base, and the county Highway Department (3500 State Highway 310, Manitowoc; 920-683-4353) is the point of contact for questions about county road access and driveway permits onto county highways.
