For a parcel in or near Sturgeon Bay, a look at the Sturgeon Bay GIS map gives you the outline, the owner of record and a parcel ID. Covered here for Sturgeon Bay: where that map lives, how to search it, and what to double-check with records.
Getting started with the Sturgeon Bay GIS map
In most places the county maintains the parcel layer, so for Sturgeon Bay the go-to is the Door County parcel viewer.
Getting to the right map
Go first to the Door County parcel viewer; it covers every assessed parcel from Ephraim to Sister Bay. If the land is near Ephraim, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Brussels, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
City limits and county records
Sturgeon Bay sits in Door County, Wisconsin, and the county assessor maps its lots. As the county seat, Sturgeon Bay hosts the courthouse, so deeds and plats are filed in town. If you're looking near Baileys Harbor, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the city limits toward Forestville often falls under county rules, not municipal ones.
Keeping a record
Save a screenshot of the lot near Forestville and its record panel, which helps later when you ask the assessor or a title company.
Offices that can help
If the acreage or value on a parcel near Brussels looks off go to the county real property listing office, the office behind the parcel record. Questions about what you can build around Brussels go to planning, building or health offices, depending on whether the land is inside town limits.
Places you'll see on the map
Sturgeon Bay holds the county offices, home to the main records offices. Smaller places on the map include Forestville, Egg Harbor, Ephraim, and Sister Bay, where town lots give way to larger tracts. Roughly 30,562 people call Door County home (Census Bureau estimate, 2023) across some 482 square miles. Door County was formed in 1851, so old deeds can run back a long way. Features like Sturgeon Bay Shipping Canal, Mackaysee Lake, and Newport State Park are easy to spot when you zoom out from Sister Bay.
Searching the map
Vacant ground near Egg Harbor may lack an address, which means panning to it and clicking. In and around Egg Harbor, searching by parcel number never misses, and you'll find it on tax statements.
When the map won't load
If the viewer stalls on a phone near Egg Harbor, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Land on the county line
Door County touches Benzie County, MI, Delta County, MI, Leelanau County, MI, Menominee County, MI, and Brown County, all with their own assessor records. A tract near the line by Sister Bay may show up in two county records, so look at the neighboring map as well. For land near Ephraim, the Platbookmapper state page links every bordering county map across Wisconsin.
Reading the legal description
Wisconsin follows the Public Land Survey System, so deeds around Sister Bay reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Ephraim can be irregular. Keep the legal description for land near Egg Harbor before you request a deed or survey.
Aerials, labels and overlays
An aerial view around Ephraim shows roofs, driveways and tree lines next to the parcel edges.
Owner, value and acreage
The record for a parcel near Brussels typically lists owner, mailing address, assessed value and acreage.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near Egg Harbor are kept by the Register of Deeds. Older tracts around Ephraim can sit on a long string of deeds, so a title company earns its fee on a real sale.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Forestville, but coverage can be spotty out of town. A saved image of the lot near Brussels and its lines helps when you meet an owner or agent.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so a fence near Ephraim often sits a few yards off the line on screen. For acreage around Ephraim, records update in batches, so a deed recorded last month can take weeks to appear.

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.
