Town of Delafield, WI

The Town of Delafield is older than the city that shares its name. Wikipedia's town entry,_Wisconsin) says it was first named Nemahbin and that the territorial assembly changed the name to Delafield in 1844. The settlement at the outlet of Nagawicka Lake grew inside the town for more than a century, until it incorporated as the separate City of Delafield in 1959.

That split explains the map today. The city took Nagawicka Lake and the downtown. The town kept the countryside around it: the western end of Pewaukee Lake, the hills south of I-94 that include Lapham Peak, farmland that has turned into subdivisions since the 1970s, and the unincorporated crossroads of Buena Vista. The two share the 53018 ZIP code, the Delafield-Hartland sewer plant and Lake Country Fire and Rescue, but almost nothing else. For Nagawicka Lake and downtown, see the Delafield city guide.

The town's government has stayed small. Its 2026 referendum page lists one full-time administrator and two part-time assistants at town hall and a five-person highway department. Police protection comes by contract from the Waukesha County Sheriff, fire and rescue from Lake Country Fire and Rescue, and building inspection, planning, engineering and assessing from outside firms. For a buyer, that means many questions about a parcel go to the county or a contractor.

Lapham Peak carries the oldest story. Wikipedia's Lapham Peak entry says a local landowner built a tower on the hill in 1851 and charged visitors to climb it, and that in 1870 the Army Signal Corps set up a station there, where the scientist Increase Lapham made weather observations tied to the first national weather forecast.

The town sits on both sides of I-94 about 24 driving miles west of downtown Milwaukee. Wikipedia puts it at 20.7 square miles, 2.1 of them water, almost twice the size of the city. It borders the City of Delafield on the west and the City of Pewaukee on the east, with Hartland to the north.

The water is Pewaukee Lake. The Wisconsin DNR lake page lists it at 2,437 acres with a maximum depth of 45 feet, moderately clear water and three public boat landings. When I checked the shoreline against the Census Bureau's boundary files in October 2026, the western end of the lake, along both its north and south shores, came back in the Town of Delafield. The eastern part is in the City and Village of Pewaukee. The town also holds a few small named ponds and lakes, among them Etter Lake and Salow Lake on OpenStreetMap, but no other large lake. Nagawicka Lake is entirely in the city and the Village of Nashotah.

The housing is mostly owner-occupied single-family homes. The 2020-2024 Census ACS counts 3,298 housing units. About 87% are single-family detached homes. Of the 3,089 occupied homes, 2,851, about 92%, are owner-occupied. The ACS puts the median value of an owner-occupied home at $613,300. The decade with the most building was the 1990s, with 964 homes, about 29% of the stock. Another 199 units, about 6%, are classified as seasonal or recreational.

The roads to know are I-94, State Highway 83, County Road C to Lapham Peak, County Road KE toward Hartland and the Silvernail frontage road along the interstate. Town hall is at W302 N1254 Maple Avenue. From Lake County, Illinois, the closest comparison I can give people is an unincorporated township area with a large lake on one edge and a state park on the other, and a separate city next door for shopping.

Pewaukee Lake is busy on summer weekends. Lake lots can be narrow, and the Delafield Shoreland Overlay can hold a rebuild well back from the water. Many homes are on septic. And at about 1 hour 45 minutes from Vernon Hills, it is a longer drive than Geneva Lake.

From the North Shore, the closest comparison on price is a lakefront home in Lake Forest at well under half the tax rate per dollar of value, with a longer drive.

The Town of Delafield sorts into four kinds of property: Pewaukee Lake frontage, the subdivisions north of I-94 toward Hartland, the wooded hills south of I-94 around Lapham Peak, and the remaining farm and estate parcels. The useful way to search is by area first and then by school district and sewer service, because both change from one side of the lake to the other.

The Pewaukee Lake shore is the luxury market and the densest part of the town. Lots in the town's Residential Lake district can be as small as 20,000 square feet with 100 feet of frontage, so lake homes can sit close together, and the $3.3 million 2025 sale was a 1956 house on a half-acre. Most of the lakeshore is served by the Lake Pewaukee Sanitary District for sewer.

North of I-94, subdivisions fill much of the land between the lake, Highway 83 and the Hartland line, and this is where the Thomas Farm subdivision was approved in 2024. South of I-94, the land rises into the Kettle Moraine. Lots are larger, roads curve through woods, and Lapham Peak's state forest land borders many parcels.

The estate and acreage parcels are scattered, mostly south and west. The town's zoning still has agricultural districts with 35- and 40-acre minimums, which is why large wooded parcels survive a few minutes from the interstate.

Pewaukee Lake is the largest lake in Waukesha County's Lake Country. A Lake Country brokerage's March 2026 lake comparison calls it the region's busiest lake and puts it at about 2,500 acres, with skiing, wakeboarding, sailing and fishing. The Village of Pewaukee sits on its eastern end with restaurants and a beach park. The town holds the western end.

The clearest recent public sale in the town is from April 2025. BizTimes reported that a Pewaukee Lake home in the Town of Delafield sold for $3.3 million. It was a one-story ranch of 3,437 square feet, built in 1956, on a half-acre lot, with three bedrooms, and it had won a 2024 remodeling award. That is about $960 per square foot of house, which tells you the frontage carried most of the price.

Across the lake, the City of Pewaukee side has set higher marks. BizTimes reported in March 2022 that an 8,187-square-foot home on 1.4 acres on Rocky Point Road in the City of Pewaukee sold for $4.76 million, against a 2021 assessment just under $3.5 million. Those sales are not in the town, but they set the ceiling buyers compare against on the same water.

The town's own numbers fill in the rest. Its 2026 referendum page puts the median assessed home at $683,950, the average at $802,469 and the highest assessed value in the town at $5,079,400. The 2020-2024 Census ACS counts 486 owner-occupied homes valued at $1 million or more, about 17%, and 89 valued at $2 million or more, about 3%. The margins on those counts are wide.

Here is the honest price picture. Pewaukee Lake frontage in the town is a $2 million-plus market, and a renovated house on good frontage can clear $3 million even on a half-acre. Off-lake homes in the subdivisions trade much closer to the town's median. Acreage south of I-94 is its own market, priced by land, privacy and whether the parcel can be divided. It is not an eight-figure market; for that, the reported sales are on Pine Lake in Chenequa.

The Lake County, Illinois buyers I talk to who look north at Wisconsin lake property usually start with Geneva Lake. Pewaukee Lake comes up when they want a big, active lake for wake sports about 25 minutes from Milwaukee.

This is the section most Illinois buyers skip and most regret skipping. In the Town of Delafield, two sets of rules govern a lake lot: the town's zoning code, and Waukesha County's shoreland ordinance. The town's welcome page says that if you are within 1,000 feet of the lake you are likely in the shoreland district, and that questions about building there go to the county's Planner of the Day.

The county rules start with 75 feet. The Waukesha County Shoreland Protection Ordinance, effective December 2024, applies to unincorporated towns within 1,000 feet of a lake. It requires every structure to sit at least 75 feet from the ordinary high-water mark. The first 35 feet inland from the water is a vegetation buffer where clearing is banned except for routine maintenance and one access and viewing corridor no wider than 35% of the frontage or 10 feet, whichever is greater, and never more than 200 feet.

Then the town gets its own overlay. Section 37 of the county ordinance creates the Delafield Shoreland Overlay District for shoreland in the Town of Delafield. On Pewaukee Lake it requires a shore setback of more than 75 feet and up to 150 feet. Where both neighboring homes sit on adjacent lots within 200 feet and both are set back more than 75 feet, a new house must match the average of their setbacks, with anything past 150 feet counted as 150. The overlay also keeps accessory buildings at least 10 feet from other buildings. It was created in 2014 and amended in 2016 and 2019.

In plain terms: on the town's Pewaukee Lake shore, you cannot assume a teardown can come forward to 75 feet. If your neighbors sit at 120 feet, you may be held near 120 feet too. Before you pay for a lot you plan to rebuild on, have the county measure the neighbors' setbacks.

The town's zoning sets the rest. In the town's Chapter 17 zoning code, the Residential Lake district covers lots on any lake. It requires 20,000 square feet of lot area, 100 feet of width and 100 feet of frontage at the shore, and caps the house at 30 feet tall. It allows one boathouse per lot of 200 to 600 square feet, no more than 20 feet wide along the shore, 35 feet deep and 12 feet above the high-water mark, built with frost footings and garage-style doors to the lake, and no metal boathouses. Detached accessory buildings are limited to two, with 1,200 square feet combined.

Piers follow state law. The Wisconsin DNR Pier Planner (April 2026) says a new pier needs no DNR permit if it is no more than 6 feet wide, has a loading platform of 200 square feet or less, and reaches only to the 3-foot depth or the depth needed to moor a boat. It allows two slips for the first 50 feet of shoreline and one more for each additional full 50 feet. A 100-foot town lake lot gets three.

Pewaukee Lake is run jointly. The town's Chapter 21 adopts the same summer and winter rules as the City and Village of Pewaukee, enforced by a joint Water Safety Patrol under the Village of Pewaukee police chief, with citations returnable to the Village of Pewaukee municipal court. A Lake Patrol Advisory Committee with one elected official each from the town, the City of Pewaukee, the Village of Pewaukee and the Lake Pewaukee Sanitary District handles no-wake zones, flooding and the patrol budget, and posts a wake sports map for the lake.

The speed rules in Chapter 21 are simple. The lake-wide limit is 50 mph. From noon to sunset on Saturdays, Sundays, Memorial Day, the Fourth of July and Labor Day it drops to 40 mph. From sunset to one hour after sunrise it is 10 mph. Boats must stay at slow-no-wake within 200 feet of any shore and near swimmers, canoes, sailboats, public accesses and mooring areas. Running a boat in tight circles or figure eights under 300 feet across while making a wake is banned. Houseboats and boats with camping facilities are banned unless the patrol permits them, and mooring for more than 24 hours is limited to riparian owners.

Winter has its own chapter. On the ice, snowmobiles are held to 50 mph in daylight and 25 mph at night, cars and trucks to 20 mph, and anything to 10 mph within 200 feet of an ice shanty or parked vehicle. Parking in the shore zone is banned from 1:30 a.m. to dawn.

Public access is easy. The DNR lists three public boat landings on Pewaukee Lake, and the town's lake patrol page names a West Pewaukee Lake boat launch. A home in the town without frontage still gets you onto the lake as a day user. What frontage buys is your own pier, and on a busy summer weekend that is worth a lot.

Off the lake, the Town of Delafield's zoning table explains why large lots survive here. Per the town's Chapter 17, the R-1 residential district requires 1.5 acres and 200 feet of width, R-1A requires 1 acre and 150 feet, R-2 requires 30,000 square feet and R-3 20,000 square feet. The agricultural districts go much larger: A-3 requires 2 acres, A-2 requires 3 acres, A-E requires 35 acres and A-1 requires 40 acres, with A-1 land divisible only as a planned unit development. Every house must have a private garage of at least 480 square feet, and attached garages are capped at 1,440 square feet.

For an estate buyer, the zoning district is the first question on any parcel over a few acres. A 20-acre parcel in A-1 cannot simply be split into building lots, and a 3-acre parcel in A-2 may already be at its minimum. The town's zoning map is on its website, and the county's Planner of the Day handles anything inside the shoreland district.

Rentals are limited. The town's vacation rental page says rentals of six days or fewer are prohibited. Rentals of seven days or more need a town vacation rental license and a state tourist rooming house license, with occupancy, parking, septic and guest register rules. The town's public list showed three licensed rentals in October 2026. If you are counting on weekend rental income from a Pewaukee Lake house, the town will not provide it.

Zillow does not publish a separate index for the Town of Delafield, so the closest current measure is the ZIP code the town shares with the city. Zillow's home value index put the typical home in 53018 at $695,244 in August 2026, up 5.8% from a year earlier, and the top tier at $1,099,461, up 6.0%. Zillow's Delafield city index was $766,469. Nearby, Zillow's typical value was $570,804 in Pewaukee and $672,143 in Hartland.

The town's own assessment data is the most useful local number I found. Its 2026 referendum page lists 3,563 taxable parcels, a total assessed value of $2,664,453,900, a median assessed home of $683,950 and an average of $802,469. The state puts the town's assessments at 99% of full value, so those assessed figures sit very close to the state's market estimate.

The Census numbers run a little lower. The 2020-2024 ACS puts the median owner-occupied value at $613,300, with a margin of about $32,000. The ACS is a five-year survey of owner estimates, so it lags. It shows the bulk of homes between $500,000 and $1 million: 1,354 of 2,851 owner homes, about 47%.

The housing is younger than the city's. The ACS counts 357 homes built before 1940, many of them lake cottages, and 756 built since 2000, about 23%. Rentals are rare: 238 occupied homes are rented, about 8%. The Thomas Farm subdivision, covered below, is the largest new supply in years.

I'm not using MLS statistics on this page. Wisconsin sold data comes through a different MLS than the Illinois one I work in, and a town-wide median would mix lake lots, subdivisions and acreage. For a specific house, the recent sales on the same shore or in the same subdivision are the numbers worth using.

Coming from Lake County, Illinois, the tax bill is the first thing people compare, and the Town of Delafield compares well. The DOR's 2025 Town, Village and City Taxes report, covering taxes levied in 2025 and collected in 2026, shows $24,022,118 in property tax on $2,682,197,600 of full value in the town. That is a gross rate of about $8.96 per $1,000 and an effective rate of about $7.73 after the state school levy credit. Assessments are at 99% of full value, so the rate on a town bill, which is applied to assessed value, works out to about $7.81 per $1,000 assessed by my arithmetic.

The school district moves the real number, and the town is split almost in half. By the DOR's figures, about 50% of the town's taxable value is in the Kettle Moraine School District, about 48% is in the Hartland-Lakeside K-8 district plus Arrowhead Union High School, about 2% is in Lake Country plus Arrowhead, and a handful of parcels are in the Waukesha district. The Department of Public Instruction's 2025-26 mill rates are 6.78 for Kettle Moraine, 3.37 for Hartland-Lakeside plus 1.84 for Arrowhead (5.21 combined), and 5.03 for Lake Country plus Arrowhead. The gap between Kettle Moraine and the Hartland-Lakeside pair is about $1.57 per $1,000.

That split runs through Pewaukee Lake. When I sampled the town's shoreline against the Census Bureau's school district boundaries, the north shore and the west end came back in Hartland-Lakeside and Arrowhead, and the south shore came back in Kettle Moraine. The tax bill names the district for each parcel, so check it.

Here is a worked example. A $3,300,000 Pewaukee Lake home at the town's 2025 effective rate of $7.73 per $1,000 would carry about $25,500 a year. The school district could move that by roughly $5,200. For comparison, Ownwell's data for Lake Forest, Illinois shows a median effective rate of 1.87%, which on the same $3,300,000 would be about $61,700.

The town levy may rise. The town's referendum page says voters were asked on August 11, 2026, to let the town exceed its levy limit by $450,000 a year for 2027 through 2030 to fund Lake Country Fire and Rescue and roads. The town estimated that at about $0.18 per $1,000 of assessed value, or about $121 a year on the median assessed home. Check the result with the town clerk; I could not confirm it.

Two Wisconsin credits come off the bill afterward. The lottery and gaming credit applies only to a Wisconsin resident's primary residence, figured for 2025-26 on up to $27,000 of value per the DOR's November 2025 notice times the school tax rate, roughly $135 to $185 here by my arithmetic. The first dollar credit applies to every improved parcel. Sewer district charges appear as their own line on the bill. Waukesha County collects the town's taxes in two installments, due January 31 and July 31, per the town's tax page.

When you sell, Wisconsin charges a real estate transfer fee of $3 per $1,000 of value. On a $3,300,000 sale that is $9,900.

This is general information, not tax advice. Your actual bill depends on the parcel, the assessment, the school district and the credits you qualify for.

The Town of Delafield is split between two public school models, almost evenly by value. The southern and western parts of the town, including the south shore of Pewaukee Lake and the Lapham Peak area, are in the Kettle Moraine School District, a K-12 district. The northern part, including the north shore and west end of the lake, is in the Hartland-Lakeside Joint No. 3 district for kindergarten through eighth grade, which feeds Arrowhead Union High School. A small area is in Lake Country, which also feeds Arrowhead. Wikipedia's town entry,_Wisconsin) describes the same split. Confirm each address with the district before you write an offer.

Kettle Moraine offers several high school options. Ask the district how enrollment in each works.

The Town of Delafield has no municipal water. Its home page says the town has no municipal well, so every home uses a private well, and the town urges owners to test their water. Sewer depends on where you are. The town's welcome page lists three situations.

Around Pewaukee Lake, most homes are in the Lake Pewaukee Sanitary District, which the town says serves generally the whole lake and its watershed and shows as its own line on the tax bill. The district announced a quarterly sewer user fee of $197 starting with the April 2025 billing, and it also runs aquatic plant harvesting on the lake. A second group of homes is in the Delhart sewer district, billed quarterly through the Village of Hartland, with wastewater treated at the Delafield-Hartland plant. Everyone else is on a private septic system and hires their own hauler.

For a buyer, that means a well test on every purchase and a septic inspection on many. Waukesha County Environmental Health offers a well and septic evaluation for a sale and asks for the application at least two weeks before your deadline. Every septic system in the county is in a maintenance program that requires pumping or inspection on a schedule. On an older lake cottage, ask whether it is connected to the sanitary district or still on a holding tank or septic, and on acreage, ask whether the system was sized for the bedroom count you plan.

Services come by contract. The town's law enforcement page says police protection is contracted from the Waukesha County Sheriff's Office. Fire and rescue come from Lake Country Fire and Rescue, of which the town pays 24.21% of the budget under the new cost-sharing formula on its referendum page. Garbage is contracted to GFL, and the town's assessor, building inspector, planner and engineer are outside firms.

Lapham Peak is inside the town. The town's parks page places the Lapham Peak Unit of the Kettle Moraine State Forest within its borders, off County Road C between I-94 and Highway 18. The DNR's Lapham Peak page describes a 45-foot observation tower on the highest point in Waukesha County, 1,233 feet above sea level, and lighted cross-country ski trails. Wikipedia adds more than 25 miles of trails, a segment of the Ice Age Trail, a backpacking campsite and the SummerStage outdoor theater.

The town runs four park areas of its own. The largest is the Sports Commons, with two baseball fields, a soccer and lacrosse field, sand volleyball, a playground, a pavilion with grills and a skate park. Del-Town Park has a softball field, Elmhurst Park a playground and pavilion, and a park area along County Road KE has a walking path. The town notes a trail along Cushing Park Road that links the Glacial Drumlin State Trail with the Lake Country Recreational Trail, which runs through the town between Oconomowoc and Waukesha.

For everyday errands, the town has no downtown of its own. Groceries, restaurants and shops are in the City of Delafield, Hartland and Pewaukee, each a few minutes away. That is the trade for the lot sizes and the state forest next door.

The largest project is Thomas Farm. BizTimes reported in January 2024 that the town board approved, 3 to 2, Neumann Developments' plan for 212 housing units on about 150 acres north of I-94 between Glen Cove Road and Elmhurst Road, near Pewaukee Lake. The plan called for 155 single-family homes on lots of 10,000 to 20,000 square feet and 56 ranch-style duplex condominium units, with a clubhouse, pool and trails, and nearly half the site kept as open space. Neumann's representatives said at the time that starting prices would likely be in the low $500,000s for the smaller homes and condos, the $600,000s for medium homes and around $750,000 for the largest. The developer estimated $130 million in added tax base.

Construction is visible elsewhere too. In October 2026 the town's home page posted a notice of blasting at Welshire Farm as part of ongoing development, noting that the state licenses blasting. The town's community projects page lists I-94 resurfacing from Highway 83 to Highway 16 (2024), Highway 83 improvements from Golf Road to Vettelson Road (2025), the Silvernail frontage road rebuild (2026), County Highways KE and E (2028), the I-94 County Road C bridge, a cell tower and a Pewaukee Yacht Club and sailing school project (2025).

For a buyer near any of these, read the plan documents and ask about construction timing.

The Town of Delafield is a Milwaukee-area town, and from Lake County, Illinois it is beyond the 90-minute line. These are free-flow estimates from OpenStreetMap routing (OSRM), computed in October 2026 from the center of the town near I-94. Real trips vary with traffic and season, and the lake and Lapham Peak ends of the town are each a few minutes from that point.

Vernon Hills is about 82 miles away, roughly 1 hour 45 minutes, and Lake Forest about 78 miles, roughly 1 hour 40 minutes. Downtown Chicago's Loop is about 108 miles, roughly 2 hours 19 minutes, and O'Hare about 104 miles, roughly 2 hours 28 minutes. Downtown Milwaukee is about 24 miles and 36 minutes away, and Milwaukee Mitchell Airport about 29 miles and 46 minutes. Madison is about 56 miles and 72 minutes west, and Lake Geneva about 44 miles and 66 minutes south.

The route from Lake County is north on I-94 through Kenosha and Racine Counties to the Milwaukee area, then west on I-94 to the Highway 83 or County Road C exit. Amtrak's Hiawatha to Chicago Union Station leaves from the Milwaukee Intermodal Station, about 23 miles and 34 minutes from the town, and from the Milwaukee Airport station. Metra does not reach this far north.

For an Illinois buyer, this is the main trade-off. On the same routing, Lake Geneva is about 42 miles and 59 minutes from Vernon Hills. Pewaukee Lake is closer to an hour and three quarters.

The Town of Delafield has no police department of its own. Per the town's law enforcement page, police service comes by contract from the Waukesha County Sheriff's Office, and on Pewaukee Lake the joint Water Safety Patrol handles the water and ice. I don't characterize the safety of any town or neighborhood. If you want the data, contact the Sheriff's Office or look it up yourself in the FBI's Crime Data Explorer.
