Shopping for acreage near Druecker? While you compare Ozaukee County land for sale, spend some time with the free parcel map and public records. In this Ozaukee County guide: finding vacant parcels, confirming road access and size, flood and zoning checks, and the records to pull.
Researching Ozaukee County land for sale
On the Ozaukee County parcel viewer, vacant land often shows a zero or low improvement value, which helps when scanning around Port Washington.
Pulling up a parcel
Go first to the Ozaukee County parcel viewer; it maps every assessed parcel around Lake Michigan and Decker. Without an address in hand, pan along Interstate 43 until the lines appear, then click inside the one you want. With a lot near Port Washington, the record panel typically gives the owner of record, assessed acreage, a parcel ID and often a sale date.
Is the tract reachable?
Confirm the parcel touches a public road or has a recorded easement, as lenders near Port Washington may balk at no access.
Flood, wetlands and soils
Check the tract near Mequon on FEMA's Flood Map Service Center for mapped flood zones; the National Wetlands Inventory mapper gives a first look at wetlands.
Mineral and timber rights
Rights below the surface near Dacada may belong to someone else, so read the deed and ask the title company.
Places you'll see on the map
Port Washington holds the county offices, where most land records are kept. You'll also find Cedarburg, Mequon, Bayside, and Belgium, where town lots give way to larger tracts. Around 93,460 people live in Ozaukee County (Census estimate, 2023) spread over about 233 square miles. Ozaukee County dates to 1853, so old deeds can run back a long way. Places such as Lake Michigan and Lion's Den Gorge Nature Preserve help you orient on the aerial.
Visiting the tract
Walk the land near Decker Corner and look for markers, fences and trails, noting road condition, neighbors and noise; none of that shows on a map.
Land on the county line
Ozaukee County meets Muskegon County, MI, Oceana County, MI, Milwaukee County, Sheboygan County, and Washington County, all with their own assessor records. A tract near the line by Druecker can show up in two county records, so check the adjacent map as well. Out toward Grafton, our state page links each neighboring county map for Wisconsin.
Rules that come with the land
If a tract near Lake Michigan carries a farm or timber classification, ask the county real property listing office what happens to taxes.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Lion's Den Gorge Nature Preserve, so load it before you lose signal. A saved image of the lot near Grafton and its lines helps when you meet an owner or agent.
Getting answers from the right desk
For assessment questions about property around Waubeka go to the county real property listing office, which maintains the tax roll. Zoning, permits and septic questions near Mequon need the planning or permitting office, depending on whether the land is inside town limits.
Limits of the parcel data
Tax maps are drawn for assessment, not measured on the ground, so a fence near Port Washington may sit some distance off the line on screen. Around Cedarburg, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Reading the legal description
Wisconsin is laid out under the Public Land Survey System, so deeds around Waubeka reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Grafton odd-sized. Copy the legal description from the record for the parcel near Mequon before you request a deed or survey.
The paper trail behind a parcel
When the details count, pull the recorded deed through the Register of Deeds; the parcel line is a drawing of it, which applies near Lake Michigan as much as anywhere. If the land is near Lake Michigan, use the instrument number shown in the record panel to skip a name search.
Questions about the Ozaukee County land for sale
Who does soil testing for septic for land near Mequon?
Short answer: the health department near Fredonia sets septic rules; alternatives can cost more.
Are sale prices on the parcel record near Lake Michigan?
For a tract near Bayside, an appraiser gives the most reliable value.
What should I check before building near Waubeka?

What's the tax parcel number used for near Decker Corner?
It's the number the county real property listing office uses to track a tract near Lion's Den Gorge Nature Preserve; you'll see it in the viewer and on tax statements.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
