New Berlin, WI

New Berlin started as a farm town. The city's history page says the first landowners, Sidney Evans and P.G. Harrington, arrived in 1836. The township was first called Mentor, and Evans renamed it New Berlin on January 13, 1840. Wikipedia's city entry adds that he named it after his hometown of New Berlin, New York.

For a century the place grew slowly. The city's own figures put the population at 1,293 in 1850 and 5,334 in 1950. Then the suburbs arrived. By 1960 the count had nearly tripled to 15,788, and the town incorporated as the City of New Berlin in 1959. Commerce in the farm era clustered in two spots: Prospect Hill near Racine and National Avenues, and New Berlin Center near National Avenue and Calhoun Road.

Prospect Hill is still marked. The city's Historic Park page describes it as an early crossroads, a hamlet of about 200 residents with mills, blacksmith and cooper shops and a tree nursery around the turn of the 20th century. The Landmarks Commission designated it a local historic district on November 19, 1991.

The oldest working site in the city is at Linnie Lac on College Avenue. Per the city's landmark page, Hugh Wedge and Isaac DeWitt built Waukesha County's first sawmill and dam there in 1836. Later owners ran grist and flour mills on Hales Millpond into the 1890s. In the 1920s the shore was subdivided and renamed Linnie Lac. After flooding threatened the dam in June 1997, nearby homeowners formed the Linnie Lac Management District, took ownership of the dam and repaired it by 2000.

A third crossroads, the Hamlet of Calhoun at Calhoun Road and the old Chicago and North Western rail line, was where farmers, grocers and the railroad did business. The city notes it was designated a Waukesha County landmark in 2004. The rail line still runs through the city: Wikipedia lists the Union Pacific line between Milwaukee and Waukesha among New Berlin's transportation routes.

The industrial base came with the suburbs. Wikipedia dates the New Berlin Industrial Park to 1964 and counts three business parks totaling 1,126 acres today. That base is a large part of why the city's tax roll looks the way it does, which I cover in the tax section.

New Berlin is a large, square suburb. Wikipedia describes it as a six-by-six-mile square in the southeast corner of Waukesha County, covering 36.88 square miles, of which only 0.44 square miles is water. Milwaukee County is on the east, Brookfield and Elm Grove to the north, the City of Waukesha to the west and Muskego to the south. Interstate 43, State Highway 59 (Greenfield Avenue), Moorland Road and National Avenue are the main roads.

Here is the plain statement for anyone arriving from a search about Wisconsin lake homes. New Berlin is not a lake market. The city has no large recreational lake, and its water area is small ponds and the Linnie Lac millpond.

The housing is mostly owner-occupied single-family homes. The 2020-2024 Census ACS counts 40,270 residents and 17,577 housing units. Of the 17,064 occupied homes, 13,047, about 76%, are owner-occupied. About 69% of all units are single-family detached houses, and another 1,168 are attached single-family homes. Buildings of 20 units or more account for 1,789 units, most of them along the Moorland Road and City Center corridors.

The median home here is a little newer than in the older inner suburbs. The ACS puts the median year built at 1978. About 20% of homes date from before 1960, and about 16% were built in 2000 or later. The 1960s through the 1990s each added roughly 2,500 to 3,000 units, which is the ranch, split-level and two-story stock most buyers will tour.

New Berlin has no recreational lake, its commercial life runs along arterial roads, and only about 1.4% of owner homes are valued at $1 million or more. The Rockwell campus will change the area around Moorland and College for anyone nearby. The school district split also means two houses a block apart can carry different tax rates.

New Berlin reads best from east to west. The east side, closest to Milwaukee County, filled in first after World War II with smaller lots and 1950s and 1960s homes. The middle of the city, along Moorland Road, holds the City Center, the library, apartments and the commercial strip. The west and south sides kept more farmland longer, and that is where most of the new single-family subdivisions of the last ten years were approved.

The city's development projects pages are the best public record of what is being built. I read through them for this guide. The pattern is clear: rezonings from agricultural to residential on the west and south sides, often as conservation subdivisions that set aside open space, and apartment and mixed-use projects concentrated on the Moorland Road corridor.

The school district line matters as much as the subdivision name. Most of the city is in the New Berlin School District, but parts of the east side are in West Allis-West Milwaukee, a strip on the north is in Elmbrook, and a sliver is in Muskego-Norway. Each carries a different tax rate, covered below. When I look at any New Berlin address, the district on the tax bill is the first thing I check.

The sub-items below are pockets the city itself names in its planning and landmark records. Rough locations come from those records; treat the boundaries as approximate and confirm against the plat.

New Berlin is not an estate town in the North Shore sense, but it does have land, and that is the reason some buyers choose it over Brookfield or Elm Grove. The west and southwest parts of the city still carry agricultural zoning, and the newest subdivisions there are built around large lots and preserved open space.

The clearest example is Kohler Ridge. The city's project page describes it as a 47-lot conservation subdivision on W. Lawnsdale Road with single-family lots of about three-quarters of an acre, served by private wells and septic systems. The Common Council approved its final plat on January 24, 2017. Turnberry Estates, a 9-lot conservation subdivision at 17700 W. Beloit Road, had its final plat approved in November 2017.

The newest proposal is the biggest. In February 2026, Hoodline reported that a Muskego custom builder filed plans for 24 luxury homes on about 72 acres of farmland on West Coffee Road near Calhoun Road. That is roughly three acres of land per home before roads and open space. The city's Five Fields concept page shows a neighborhood meeting on February 17, 2026, a Plan Commission site walk the next day, and a Plan Commission discussion on May 4, 2026 with no action taken. It still needs rezoning and plat approval, so treat it as a proposal.

Acreage also turns up in the resale market. In July 2024, NBC Chicago reported a 17-acre New Berlin property on S. Springdale Road with a private pond and indoor pool listed at $1.4 million. That listing is two years old and I don't know what it sold for. It shows the scale available on the west side.

The honest price picture for the top of New Berlin comes from the Census. The 2020-2024 ACS counts 180 owner-occupied homes valued at $1 million or more, about 1.4% of the total, and 558 at $750,000 or more, about 4.3%. Zillow's top-tier home value for the city, the typical value of the most expensive third of homes, was $604,512 in August 2026. If you are shopping above $2 million, New Berlin will offer very few choices.

New Berlin is a steady mid-priced market. Zillow's home value index put the city's typical home value at $455,414 in August 2026, up 5.3% from $432,528 in August 2025. The top-tier value was $604,512, up 5.0%. By ZIP code, Zillow's August 2026 typical value was $457,044 in 53151 and $450,039 in 53146, with top-tier values of $598,462 and $657,099.

For context, Zillow's August 2026 typical value was $528,294 in Brookfield, $423,254 in Waukesha and $530,269 in Muskego. New Berlin sits in the middle of its neighbors, below Brookfield to the north and Muskego to the south, above the City of Waukesha to the west.

The Census figures run lower because they lag and because they are owners' own estimates. The 2020-2024 ACS puts the median value of owner-occupied homes at $365,700, with 4,351 homes, the largest group, valued between $300,000 and $400,000. Median gross rent was $1,426 a month. The state's 2025 equalized value for all taxable property in the city was $8,404,437,700.

The ACS value bands show where the stock sits. Of 13,047 owner-occupied homes, 4,351 were valued at $300,000 to $400,000, 2,877 at $400,000 to $500,000 and 1,597 at $500,000 to $750,000. Only 964 were valued under $200,000. That is a narrower spread than in the older inner suburbs, and it matches the city's build history: most homes went up between the 1950s and the 1990s on lots large enough that additions and full rebuilds are common.

The two sources tell the same story from different angles. Zillow's index tracks all homes month by month; the ACS is a five-year survey of owners' estimates. Both put New Berlin in the $350,000 to $600,000 band for most homes, with a thin layer above that.

I'm not using MLS statistics on this page. Wisconsin sold data comes through a different MLS than the Illinois one I work in. For a specific house, recent sales in the same subdivision and the same school district are the numbers worth using.

Coming from Lake County, Illinois, the tax bill is the first thing people compare, and New Berlin compares well. Wisconsin bills are built from a mill rate, the dollars of tax per $1,000 of assessed value. New Berlin's 2025 rates, for taxes collected in 2026, are on the city's 2025 tax sheet, dated November 24, 2025.

The rate depends on the school district. After the state school levy credit, the 2025 rate is $12.38 per $1,000 of assessed value in the New Berlin School District, $11.78 in the Muskego-Norway portion, $12.60 in the Elmbrook portion, $12.96 in a New Berlin district area that also pays the Milwaukee technical college levy, and $15.35 in the West Allis-West Milwaukee portion. The city's tax levies page confirms the four districts. By the Wisconsin DOR's 2025 report, the New Berlin School District holds about 93% of the city's taxable value, West Allis-West Milwaukee about 5% and Elmbrook about 2%.

Assessed value is not market value. The city sheet puts the 2025 assessment ratio at 88.57%, so a home worth $600,000 on the market would be assessed at about $531,400. The DOR's report puts the city-wide effective rate at about $11.11 per $1,000 of full market value after the school credit.

Here is a worked example. A $600,000 New Berlin home in the New Berlin School District would carry about $6,580 in 2025 taxes, by my arithmetic: $531,400 assessed times $12.38 per $1,000. The same home would be about $6,700 in the Elmbrook area, $6,260 in the Muskego-Norway area and about $8,160 in the West Allis-West Milwaukee area. For comparison, Ownwell's data for Vernon Hills (April 2026) shows a median effective rate of 2.75%, which on the same $600,000 would be about $16,500.

Two credits come off the bill. The lottery and gaming credit applies only to a Wisconsin resident's primary residence; in 2025 it was $163.69 in the New Berlin district and $220.78 in the West Allis-West Milwaukee area, per the city sheet. The first dollar credit, $54.56 in the New Berlin district, applies to every improved parcel.

One change is on the ballot. On November 3, 2026, voters decide whether the city can raise its levy by $3,122,149 a year, 8.1% of the levy, to add 12 firefighter-paramedics, a division chief and three police officers, among other positions. The Freeman reported in August 2026 that the cost would be about $156 a year on a home assessed at $375,246.

When you sell, Wisconsin charges a real estate transfer fee of $3 per $1,000 of value, or $1,800 on a $600,000 sale.

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.

Four public school districts serve New Berlin, per the city's schools page: New Berlin, Elmbrook, Muskego-Norway and West Allis-West Milwaukee. The New Berlin School District covers most of the city. Which one serves a given house depends on the parcel, so check the district on the tax bill and confirm with the district office before you write an offer.

The New Berlin district's structure is a little unusual. It runs two combined middle-high schools, Eisenhower and New Berlin West, rather than one large high school. The DPI file lists Eisenhower Middle-High at 1,095 students and New Berlin West Middle-High at 1,036 students.

For Illinois buyers, the closest comparison is a unit district with two smaller high schools. Each middle-high school has its own attendance area, so confirm which one serves the address.

Industry is a big part of New Berlin's identity and its tax base. Wikipedia counts three business parks totaling 1,126 acres, starting with the New Berlin Industrial Park in 1964. The city's 2025 tax sheet shows a city levy of about $38.3 million, and a large share of the commercial and industrial value that supports it sits in these parks. For a homeowner, that is one reason the city portion of the bill is lower than in a purely residential suburb of the same size.

The biggest project in years is Rockwell Automation's new campus. The city's project page describes a first phase of about 770,000 square feet of manufacturing and 40,000 square feet of office, about 810,000 square feet in all, with a possible 200,000-square-foot expansion and a possible second building of about 425,000 square feet along Grange Avenue later. The Daily Reporter reported on July 29, 2026 that the site covers 185 acres east of Moorland Road and south of Grange Avenue, that the project could cost up to $246 million, and that the Common Council unanimously approved the land-use plan change and rezoning on July 28. The rezoning removed residential zoning from the site. The Plan Commission approved the site and architecture plans on August 19, 2026. A tax incremental financing district, TID #6, is part of the plan.

The plan drew public comment. BizTimes reported in June 2026 on concerns raised about property values, 24-hour operations, light, noise, building height and water and energy use.

For a buyer, the practical point is location. If you are looking near Moorland Road between Grange and College Avenues, or in the newer subdivisions to the west and south of that corner, ask what the final site plan shows for buffers, lighting and truck routes.

The city keeps a running list of active projects, and it is the most reliable place to check before you buy near open land. Beyond Rockwell, the projects that matter most for homeowners fall into three groups.

Single-family subdivisions on former farmland come first, with condominiums alongside them. Theofila Estates, a 14-lot subdivision at 5715 S. Sunny Slope Road, had its final plat approved by the Common Council on February 11, 2025, per the city. Autumn Trace, a 20-lot conservation subdivision at 4908 S. Calhoun Road, was approved in October 2023. The Five Fields concept on Coffee Road was still under discussion as of May 2026.

Condominiums are a smaller part of the mix. The Hickory Hills planned development off Lynn Drive and Acorn Drive was first approved for 26 four-unit condominium buildings, or 104 units. Per the city, eight of those buildings, 32 units, were built, and in 2017 the developer asked to finish the site with 20 two-unit buildings instead, for 72 units in all. Side-by-side condos like these are one of the few ownership options outside the apartment corridor.

Multifamily and mixed use come second. The Conservancy at 1640 S. Moorland Road was rezoned for seven multifamily buildings, two mixed-use buildings and a clubhouse, with Common Council approval on June 10, 2025 and the use approval anticipated in August 2025. That is in the north-central part of the city near the Brookfield line.

The comprehensive plan comes third. The city is updating its 2030 Comprehensive Plan, first adopted in 2009 and updated in 2016, with the Plan Commission acting as the steering committee. The future land use map in that plan is what tells you whether the field behind a house is planned for homes, business or open space. Rockwell's site, for example, needed an amendment from business park and urban residential to business park and industrial.

My advice for any New Berlin house that backs onto open land is the same: pull the future land use map and the zoning for the parcels around it before you write an offer. An open field today can be a subdivision or a warehouse in a few years.

Most of New Berlin is on city water and sewer, but not all of it. The city's utilities page says the New Berlin Water Utility buys water from Milwaukee Water Works, and that Milwaukee raised its wholesale rate 3% in September 2019 and about 6.7% in April 2023. The Public Service Commission approved a New Berlin rate increase effective April 1, 2024. The water page notes the city's Lake Michigan water diversion won an engineering award, and it runs an odd-even lawn sprinkling schedule.

The west side is different. Kohler Ridge, approved in 2017, was built with private wells and septic systems, per the city's project page. Older rural homes on the west and south sides may also be on wells and septic. Ask the seller, check the utility billing record, and assume nothing from the subdivision name.

If a house has a septic system, Waukesha County Environmental Health runs the maintenance program and offers a well and septic evaluation for a sale; the county asks for the application at least two weeks before your deadline. Every system is on a pumping or inspection schedule by type, typically every three years. Ask for the records.

Sewer customers are also in the Milwaukee Metropolitan Sewerage District system. The city points homeowners to MMSD's Pipe Check program, which helps pay to repair private sewer laterals.

New Berlin's park system is large for a suburb. The city's parks page counts 29 park and recreation sites: 397 acres of developed parks, 204 acres of undeveloped parkland, 128 acres of conservancy and the 187-acre New Berlin Hills Golf Course. Malone Park, Valley View Park with its disc golf course and sledding hill, and the south side of Calhoun Park stay open until 11 p.m.

The trail most residents use is the New Berlin Trail. Waukesha County describes it as a seven-mile paved trail on the Wisconsin Electric Power Company right-of-way from S. 124th Street at the Milwaukee County line to Lincoln Avenue in Waukesha. It connects to Greenfield Park in Milwaukee County at one end and, through Waukesha city streets, to the Glacial Drumlin State Trail at the other. Access points include Sunny Slope Road, Buena Park and Springdale Road.

The county's biggest park is next door. Minooka Park, at 579 acres the largest in the county system, sits in neighboring Waukesha with a swimming pond, wooded trails and groomed cross-country ski trails.

Errands are easy. Moorland Road, National Avenue and Greenfield Avenue carry most of the shopping, and Brookfield's larger retail is a short drive north. The city lists a Saturday farmers market from May through October. For neighbors, see the sibling guides for Brookfield, the City of Waukesha and Muskego.

New Berlin is a Milwaukee suburb, and the drive from Lake County, Illinois is about an hour and a half. These are free-flow estimates from OpenStreetMap routing (OSRM), computed in October 2026 from City Hall on S. Casper Drive. Real trips vary with traffic, weather and season.

To Vernon Hills, the route runs about 67 miles and roughly 1 hour 25 minutes. To the Loop in downtown Chicago it is about 93 miles and roughly 2 hours. O'Hare is about 90 miles away, which the router put at a little over 2 hours. On the Wisconsin side, downtown Milwaukee is about 15 miles and 25 minutes, Milwaukee Mitchell Airport about 15 miles and 26 minutes, downtown Waukesha about 9 miles and 18 minutes, and Madison about 72 miles and roughly 1 hour 30 minutes.

There is no commuter rail in New Berlin. For the train to Chicago, Amtrak's Hiawatha leaves from the Milwaukee Intermodal Station, about 14 miles and 23 minutes from City Hall, and from the Milwaukee Airport station, about 16 miles and 26 minutes. Metra's Union Pacific North line ends in Kenosha, about 45 miles and an hour away, which is rarely the better choice from here.

Interstate 43 crosses the city on a diagonal, and Highway 59, Moorland Road and National Avenue carry most local traffic. For a buyer who splits time between Milwaukee and northern Illinois, New Berlin's position on the southwest side of the metro makes the southbound trip a little shorter than from the northern suburbs.

The New Berlin Police Department provides police service across the city. I don't characterize the safety of any town or neighborhood. Anyone who wants the data can contact the New Berlin Police Department directly or look up the agency on the FBI's Crime Data Explorer.
