Town of Linn, WI

The Town of Linn is older than the State of Wisconsin. According to the town's own history, it was established on January 23, 1844, four years before statehood, and named for Dr. Lewis Field Linn, a U.S. senator from Missouri who had died the year before. The first house in the town was a log cabin built in 1837 by John Powers, originally from Maine, at the east end of the lake. The lake itself got its name in 1836 from surveyor John Brink, after his hometown of Geneva, New York.

For most of its first half-century Linn was farm country. The 1880 federal census counted 823 residents. What changed it was the same thing that changed the whole lake: after the Great Chicago Fire of 1871, summer estates began going up on Geneva Lake, and much of the best of that building happened on Linn's south shore. Black Point, the 1888 summer house of Chicago brewer Conrad Seipp, is the best-preserved example and is now a state historic site (covered below).

Inland, the railroad drew the map. In 1901 the Chicago, Milwaukee and St. Paul Railway built its Chicago-to-Janesville line across the southern edge of the town, and a station stop called Zenda grew around it. The town history repeats the local story that the name came from the railroad president's daughter, who was reading *The Prisoner of Zenda*. The Linn town hall in Zenda was built in 1914 and is still where the town meets and votes.

The result is the two-part town you see today: an estate shoreline that reads as a century-old resort, and a working rural township behind it.

Linn is the largest piece of Geneva Lake. The town's history page says 14 of the lake's approximately 26 shoreline miles lie within the town, and the 2024 Census gazetteer puts Linn at 27.36 square miles of land and 6.61 square miles of water. The town's own site describes it as lying along both the north and south shores. Most of what buyers mean by "Linn" is the south shore between the City of Lake Geneva and the Village of Fontana, plus the farmland and the Zenda crossroads behind it.

Linn is a town, not a village or city, and that distinction matters in Wisconsin. A town is unincorporated. There is no downtown, and shopping, dining and most services are in the incorporated places around it: Lake Geneva to the east, Williams Bay across the lake, Fontana to the west and Walworth to the southwest. Mailing addresses follow the post office, not the town line, so a Linn house can carry a Lake Geneva, Zenda or other nearby post office address. Always check the parcel's municipality on the county's records.

The 2020-2024 Census ACS counts 2,710 residents and 2,161 housing units. Of those homes, 920, about 43%, are classified as seasonal, recreational or occasional use, and among the homes occupied year-round 84% are owner-occupied. Nearly every home in Linn, about 96%, is a detached single-family house.

The tax base is the striking number. In the DOR's 2025 Town, Village and City Taxes report, Linn's taxable full value is $3.81 billion. That is larger than the City of Lake Geneva's $2.71 billion and more than twice the Village of Williams Bay's $1.64 billion. Lakefront land is what drives it.

Linn has no downtown and every errand is a drive to Lake Geneva, Fontana or Williams Bay. Most of this shore trades privately.

Coming from Lake County, Illinois, the closest comparison is buying in an unincorporated township area, with one difference: Wisconsin towns are real local governments. Linn has a town board, a plan commission, a building inspector, a municipal court and its own police department, all run from the town hall at W3728 Franklin Walsh Street in Zenda, per the town's site.

Zoning is where the difference shows. Linn's land use plan works through Walworth County zoning districts. Its preferred pattern for new rural homes is conservation subdivisions at a density of about one lot per five acres, with lots of no more than two acres and the rest held as open space. Farm splits in the A-1 prime agricultural district need 35 acres. The plan concentrates new commercial use at the Highway 120 and Willow Road intersection and treats Zenda as the town center. If you are buying acreage in Linn to divide later, read the plan first.

Fire and EMS changed recently. The town's fire and EMS page says Linn now contracts with the City of Lake Geneva for 24/7 staffing at the Linn station at N1457 Hillside Road. The town's partnership FAQ explains why: the Linn department, founded in 1949 and paid-on-call, could no longer staff calls reliably, and the city had already been covering Linn's north shore. The FAQ puts the annual cost at $1.9 million and sets response targets of under 10 minutes in the non-rural part of town and 15 minutes in rural areas, 80% of the time or better.

For a buyer, the practical list is short: confirm the parcel is in Linn and not an adjacent village, find out which school and sanitary districts it sits in, and know that county shoreland rules apply on the water (covered below).

Linn has no villages inside it, only areas, and the price gap between them is enormous. The lakefront and lake-access areas are a different market from the farmland a mile south. I have only named places that public sources name, and the boundaries are informal.

The south shore is the core. South Lake Shore Drive and the lanes off it run past the historic estates, Black Point and a series of newer houses built on old estate sites. The Real Deal has reported addresses on Lackey Lane, Lakeside Lane, Lakeside Court and South Lake Shore Drive in this stretch. Mailing addresses here are often Lake Geneva.

Linn is where Geneva Lake's top of market lives. When a south-shore home sold for $20 million in June 2025, BizTimes reported that state property records showed only three other homes in the Lake Geneva area that had sold for more than $20 million: a 2024 sale at $21.9 million, a 2022 sale at $23.9 million and another 2022 sale at $34.4 million. All three, BizTimes said, were in the Town of Linn, and the June 2025 sale was too.

That sale was W3806 Lackey Lane. The Real Deal (June 24, 2025) described a roughly 10,800-square-foot house on a rolling 5-acre site with 500 feet of level frontage on the lake's south side, about $1,852 per square foot. It was never listed publicly and drew five ready buyers. The listing agent said the seller turned down an offer about $5 million higher from a buyer who planned to tear the house down. The Real Deal ranked it the third most expensive sale ever on the lake.

Two other south-shore sales give the range below it. In August 2024, Aloha Lodge, a Howard Van Doren Shaw design from 1900 on 12 acres at 768 South Lake Shore Drive with 368 feet of frontage, sold for $21.85 million. In August 2025, a 7,000-square-foot house in South Shore Club sold for $10.1 million after the buyers made an unsolicited offer.

The listings side tells the same story. In June 2026 The Real Deal reported Allegheny, a nearly 21-acre Shaw-designed estate from 1925 with 560 feet of shoreline on South Lake Shore Drive, listed at $24 million, the most expensive active listing in southern Wisconsin. Its acreage is under a conservation easement that prohibits subdivision.

And most of it trades before anyone outside a small circle of agents hears about it.

Linn's prices run from rural acreage to eight figures, so a single median is close to useless. Zillow's home value index for Linn was $766,093 in August 2026, up 9.4% from $700,575 a year earlier. That is the highest of the Geneva Lake communities in Zillow's file: Fontana was $680,700, Williams Bay $549,741 and the City of Lake Geneva $420,272. Redfin does not publish a Linn city series.

The Census ACS helps with the shape. The median value of owner-occupied homes is $537,100 (margin of error about $70,000). About 155 of 954 owner-occupied homes, roughly 16%, are valued at $1 million or more, and about 67, roughly 7%, at $2 million or more. Those counts leave out the 920 seasonal homes, which include much of the lakefront, so the true number of seven- and eight-figure properties is higher.

Three tiers, then. Private lakefront, where the reported south-shore sales I found sit at the very top: $20 million on Lackey Lane in 2025 and $21.85 million for Aloha Lodge in 2024. Lake access, where you buy into an association or a deeded right rather than your own frontage; the $10.1 million South Shore Club sale in August 2025 and an $8.8 million off-market purchase on Lakeside Lane in 2026, which The Real Deal says has no direct lake access, show how high that tier now reaches. And inland homes and acreage, which trade far closer to the town's medians.

The other thing to know is supply. A broker told The Real Deal in June 2025 that about 70% of lakefront deals are never formally listed, and that some buyers now pay to tear down houses that would not normally be teardown candidates. When the land is the asset, the house is often a line item.

Linn's housing stock is older than most people expect and newer than the estate photos suggest. The 2020-2024 ACS counts about 503 homes built before 1940, roughly 23% of all housing in the town. That is the estate era and the early lake cottages. The post-war decades added about 574 homes between 1940 and 1969, and the 1970s through 1990s about 519 more.

Then came a second wave. About 565 homes, roughly 26%, were built in 2000 or later, including about 360 in the 2000s alone. On the lake, much of that is replacement: a newer house on an old estate site or a subdivided parcel. Inland, it is mostly single-family homes on acreage.

Three kinds of houses come up on a Linn search. Historic estate houses, often with guest houses, carriage houses and boathouses, where the questions are maintenance, landmark status and easements. Newer lake houses on subdivided estate land, where the questions are pier rights and what the original subdivision allowed. And inland farmhouses and newer homes on acreage, where the questions are the well, the septic system and the zoning district.

The age profile has a practical consequence for inspections. A 1900s estate house or a 1940s cottage will need a different inspection team than a 2005 lake house: a structural engineer, a historic-roofing contractor, a well-and-septic inspector and, on the water, someone who knows piers and seawalls.

Linn's average tax rate is low by Geneva Lake standards, but the average hides a wide spread. In the DOR's 2025 Town, Village and City Taxes report, Linn's assessment level is 0.92, its gross full-value rate is $8.79 per $1,000 and its effective rate after the school levy credit is $7.88 per $1,000. For comparison, Fontana is $7.28, Williams Bay $8.74, the City of Lake Geneva $12.28 and the Walworth County average $10.56.

The spread comes from the schools. The Walworth County Treasurer's 2025 rate sheet lists eight school districts levying in Linn. Every Linn parcel pays the county ($2.52 per $1,000 of assessed value), the town ($1.90) and Gateway Technical College ($0.58), less a school levy credit of $0.99. Then it pays one school combination. By my arithmetic from that sheet, the net rate per $1,000 of assessed value is about $7.30 for Linn J6 with Big Foot high school, $8.82 for the Williams Bay district, $9.37 for Geneva J4 with Badger, $9.42 for Linn J4 with Badger, $11.80 for Lake Geneva J1 with Badger and $11.88 for Walworth J1 with Big Foot. Parcels in the Linn Sanitary District add a very small line.

Here is what that means on one house. Take a $5 million lakefront purchase assessed at the town's 0.92 level, or $4.6 million. In Linn J6 and Big Foot, the bill is about $33,600 a year. In Linn J4 and Badger, about $43,300. In Lake Geneva J1 and Badger, about $54,300. Same price, roughly $20,700 a year apart, before any owner-specific credits. The expectation I most often have to reset with Illinois buyers is that a town has one tax rate. In Linn it has six.

Linn also revalued recently. The town's fire and EMS FAQ uses the example of a home assessed at $1 million in 2024 and $1.7 million in 2025 after revaluation. The assessor is Associated Appraisal Consultants, and objections are filed with the town clerk by May 1, per the town's assessment page.

Two more Wisconsin rules. The lottery and gaming credit applies only to a Wisconsin resident's primary residence as of January 1 and excludes vacation homes, so a second home in Linn will not get it. Its 2025-26 maximum credit value is $27,000, per the DOR. And sellers pay the state real estate transfer fee of $3 per $1,000 of value: $15,000 on a $5 million sale. This is general information, not tax advice. Your bill depends on your parcel, your school district and your credits.

Linn has no K-12 district of its own. Most of the town is served by two one-school K-8 districts, and each one feeds a different union high school. Linn J4 runs Traver School and feeds Badger High School in the Lake Geneva-Genoa City Union High School district. Linn J6 runs Reek School and feeds Big Foot High School in Walworth. The county's list of public school districts (revised August 17, 2026) lists both, with Traver and Reek named as the schools.

Not every Linn parcel is in J4 or J6. The county's 2025 rate sheet shows the Williams Bay School District (K4-12), Lake Geneva J1, Geneva J4 (Woods School) and Walworth J1 all levying on some Linn property. Which district a house is in is set by the parcel, and it affects both the school and the tax bill (see the tax section). Check the school district on the tax bill and confirm with the district before you write an offer.

Because Linn is unincorporated, Walworth County shoreland zoning is the rulebook for building near the lake. The DNR explains that counties apply the statewide shoreland standards to unincorporated land within 1,000 feet of the ordinary high-water mark of a lake. On a Linn lakefront lot, that covers the house, any addition, the boathouse and most of the yard. Before you plan a teardown or an addition, ask the county for the parcel's zoning district, its setbacks and whether the existing house is nonconforming.

Below the high-water mark the State of Wisconsin owns the lakebed, and the DNR regulates piers, lifts and shoreline work. The town adds its own pier rules on top. If you are buying lakefront, get a current survey that shows the high-water mark and the pier, and copies of every pier, boathouse and shoreline permit. An unpermitted boathouse or an oversized pier can become the seller's problem at closing or yours at resale.

On the water, Linn joins Lake Geneva, Williams Bay, Fontana and the Town of Walworth in one Joint Uniform Lake Law Ordinance. In the copy on file with the DNR, the daytime speed limit is 35 mph from Friday noon through Sunday between May 15 and September 30 and on Memorial Day, the Fourth of July and Labor Day; 45 mph at other times; and 15 mph after sunset all year. Where no lane is marked, the traffic lane starts 200 feet from shore and 100 feet from any pier or mooring area, and inside that zone boats keep to slow-no-wake.

Easements are the last layer. Allegheny's acreage, for example, sits under a conservation easement that bars subdivision, according to The Real Deal, and Black Point's grounds and 620 feet of shoreline are under one too. Read the title commitment for easements before you assume a large parcel can be split.

Most of Linn runs on private wells and private septic systems, which is the biggest practical difference from buying in a lake village. The town's land use plan says sewer extensions should not happen without a boundary agreement with a neighboring municipality, and that the town would look into sewer service for parts of the north shore through the Geneva National Sanitary District and parts of the south shore through agreements with Fontana and Walworth. That tells you sewer is the exception.

The Linn Sanitary District publishes a report on well testing of public and private wells in the district from 2017 to 2021, guidance on maintaining private onsite wastewater treatment systems, and links to state grant programs for septic replacement. It also points to the summer E. coli test results for the town's public beaches.

For a buyer, that means two inspections that Illinois suburban buyers rarely order: a septic evaluation by a certified inspector, and a well water test for bacteria and nitrates at minimum. Ask how old the system is, whether it has ever been replaced and what it is sized for. A large house on an old system designed for a summer cottage is a common mismatch on older lake parcels.

Garbage and recycling are handled through the town. Electricity and natural gas come from the regional utilities; on a seasonal house, ask for twelve months of bills.

Every lakefront owner in Linn hosts a piece of the Geneva Lake Shore Path. VISIT Lake Geneva describes the path as a 21- to 26-mile loop, with the 20 feet along the shoreline set aside as public long ago. Owners maintain it across their own frontage, so it changes from brick to grass to stepping stones from one property to the next. Walkers are asked to stay on the path and off lawns, piers and boathouses. Bikes, skates and motorized vehicles are not allowed; leashed dogs are.

With 14 of the lake's shoreline miles, Linn carries more of the path than any other municipality. VISIT Lake Geneva notes that regular walkers consider the south side the more challenging half, with hills, narrow stretches and wooded sections close to the water. Black Point's own program list includes a guided shore-path walk.

What it means for an owner: a steady stream of walkers past the lawn on summer weekends, an obligation to keep your section passable, and a liability question to raise with your insurer.

Black Point is the one south-shore estate anyone can tour. Wikipedia) places it on the south shore in Linn and describes a Queen Anne mansion designed by Adolph Cudell and built in 1888 for Chicago brewer Conrad Seipp, with a four-story observation tower visible across the lake. It was listed on the National Register of Historic Places in 1994. The donation to the state began in 1993 and was completed in 2005, and the grounds, including 620 feet of shoreline, are protected by a conservation easement.

The Wisconsin Historical Society now runs it as one of its 12 historic sites. According to Walworth County Community News (April 14, 2026), the 2026 season opened May 2. The 20-room house sits on seven acres of gardens and natural areas, and visitors arrive by boat with Lake Geneva Cruise Line from Lake Geneva. Tickets for a cruise and house tour ran up to $55 in 2026, with daily tours from May 25 to August 30.

For buyers, Black Point is a good first afternoon on the lake. The boat ride passes most of the south-shore estates, and the interpreters explain how the estate shore was built and how its land has been divided, protected or kept intact since.

Linn runs its own lake access. The town's site lists two boat launches, off Linn Road and Hillside Road, each with a swimming beach and parking. The town's boat launch page did not show fees when I checked, so ask the town for the current season's launch and parking rates. Summer bacteria results for the town beaches are published through the lake management site linked from the sanitary district page.

Inland, the town describes Linn Nature Park as a 160-acre park for walking trails, bird watching and plant diversity. The town's land use plan keeps large areas in environmental corridors: lakes and shorelands, wetlands, woodlands, prairie, wildlife habitat and steep terrain, where development is steered away.

Everything else is a short drive. The beaches, restaurants and marinas of Lake Geneva, Fontana and Williams Bay are the town's commercial centers by the plan's own description.

Linn sits close to the state line, which makes it one of the shorter Wisconsin drives from Lake County, Illinois. I ran the routes on a public routing engine (OSRM, October 5, 2026, no traffic) from the town hall in Zenda. Treat these as estimates and add time on summer weekends: Vernon Hills about 41 miles and 60 minutes; downtown Lake Geneva about 8 miles and 16 minutes; downtown Milwaukee about 58 miles and 79 minutes; Milwaukee's Mitchell Airport about 54 miles and 75 minutes; the Chicago Loop about 76 miles and 1 hour 47 minutes. O'Hare is about 63 miles; the routing engine's time looked pessimistic, so check it on a live map.

By rail, the nearest Metra stations are in Illinois. Fox Lake, the end of the Milwaukee District North line, is about 23 miles and 31 minutes from Zenda by the same estimate, with 16 weekday trains toward Chicago in Metra's schedule feed for the week of October 5, 2026, most taking 88 to 93 minutes to Union Station. Harvard on the Union Pacific Northwest line is about 17 miles and 25 minutes away, with 14 weekday inbound trains and 92-minute early-morning runs to Ogilvie. Kenosha on the Union Pacific North line is about an hour east. Amtrak's Hiawatha between Chicago and Milwaukee stops at Sturtevant, about 66 minutes from Zenda, and at Milwaukee Airport.

The honest version: Linn works as a weekend base or a remote-work home for Chicago, and as a realistic daily commute to the northern Illinois suburbs. A daily trip to the Loop by train means a drive to Fox Lake or Harvard plus about 90 minutes on Metra each way.

Police service in Linn comes from the town's own Linn Police Department, based at the town hall in Zenda and reachable through the Town of Linn. Fire and EMS calls are covered 24/7 from the Linn station on Hillside Road under the town's contract with the City of Lake Geneva.

I don't characterize the safety of any town or neighborhood. Anyone who wants the data can contact the department or look it up on the FBI Crime Data Explorer.
