Port Washington, WI

Port Washington is a small city with a big role. It is the seat of Ozaukee County, and the county government is its largest employer, according to Wikipedia's city entry. The Census 2024 gazetteer puts the city at 5.95 square miles of land. The 2020 census counted 12,353 people, and the Department of Revenue's 2025 report estimates 12,952 for 2025.

The city sits on Lake Michigan's western shore, east of Interstate 43. Wikipedia describes the geography in three parts: clay bluffs of 80 to 130 feet on the north and south sides of the city, cut by ravines, and a low valley in the middle where Sauk Creek reaches the lake. The historic downtown and the harbor sit in that valley. Everything else in the city is up on the bluff or west of it.

The first thing I tell anyone looking here is that there are two Port Washingtons. The City of Port Washington is the incorporated city covered on this page. The Town of Port Washington is a separate rural municipality that wraps around the city on the north and west, with its own town board, its own lower tax rate and most of the area's Lake Michigan acreage. Both use the Port Washington 53074 mailing address. On October 5, 2026, I ran the top listings on a public Port Washington search page through the Census geocoder. The two highest-priced lakefront houses, on Norport Drive and Weilers Way, came back in the town, not the city.

There is a second boundary to watch inside the city. A house on Willow Pond Way in the city's southwest corner came back in the Grafton School District, with a Grafton 53024 mailing address, while most of the city is in the Port Washington-Saukville district. Coming from Lake County, Illinois, buyers tend to assume the name in the address settles the municipality and the schools. Here I'd check the tax bill for both before anything else.

The typical home is worth about $393,000, a lake-view condo or Prairie's Edge home runs from about $725,000 to $1.4 million, the 220-slip marina is downtown, and downtown Milwaukee is about 37 minutes away.

The trade-offs are concrete. The city has no $2 million tier; the true lakefront acreage is in the town, and the top of the Lake Michigan market is farther south. Bluff property needs engineering attention. The data center will bring years of construction traffic, a power-line case still under review and a change in the city's tax base whose effect on bills is a projection so far. And it is about 108 minutes from Vernon Hills.

I'd pull the tax bill and confirm the municipality, the school district and any special assessments for the exact parcel before falling for a property.

Port Washington's history is a harbor story, and it explains the shape of the city today. Wikipedia's city entry records that the site was laid out in 1835 and named for George Washington. It became the seat of the new Ozaukee County when the state legislature split Washington County in 1853. The City of Port Washington incorporated in 1882.

The lake shaped everything. Early on, ships unloaded at piers, and the shore had no natural harbor, so wrecks were common. The federal government dredged an artificial harbor at the mouth of Sauk Creek, completed in 1871, with a channel 14 feet deep and 1,500 feet long. Because the harbor is artificial, it has to be dredged every few decades to keep its channels from filling with sediment.

Two lighthouses mark that history. The 1860 light station on the bluff above downtown was decommissioned in 1903, restored with a replacement tower in 2002 and now runs as a museum of lighthouse keeping. The breakwater light, an Art Deco steel tower first lit in 1935 at the end of the north breakwater, is still an active aid to navigation and was added to the National Register in 2018.

Industry came next. Wikipedia describes a chair company that employed a large share of the county around 1900, and a lakefront power plant built in 1931 that received daily coal shipments through an expanded harbor. The plant switched to natural gas, and the harbor closed as a commercial port in 2004. The generating station now has two natural gas units, completed in 2005 and 2008, of 545 megawatts each. The downtown historic district, about 40 buildings from the 1850s to the 1950s, joined the National Register in 2000. Between 1940 and 1970 the population more than doubled, from 4,046 to 8,752, as the city annexed farmland from the surrounding towns for subdivisions.

I break the city into five areas. The boundaries are my own grouping from the geography and from where the October 2026 listings sat, so treat them as a way to read a listing, not as official neighborhoods.

The first is downtown and the harbor, in the Sauk Creek valley. This is the historic district along Franklin Street, the marina, the breakwater and the condominium buildings near the water on Lake Street and Pier Street. It is the most walkable part of the city and the part with the most condos.

The second is the north side and the north bluff, the older grid of streets climbing north from downtown along Wisconsin Street and Lake Street, with houses ranging from 19th-century homes to postwar ranches. Streets near the bluff edge, such as North Lakeview Avenue, look over the lake.

The third is the south lakefront, where the city's newest lake-view housing sits. Prairie's Edge, at Sunset Road and Lake Shore Drive according to its developer, is a 45-acre development that its landscape architects say began construction in 2018. Its developer describes lakefront cottages, townhomes, cottage-court homes and apartments, a clubhouse and a health club. The Census geocoder places its streets, Shieling Lane and Bastle Wynd, inside the city.

The fourth is the west side, the subdivisions from the 1960s onward between downtown and I-43, plus newer streets such as Sweetwater Boulevard in the Hidden Hills area, where new houses were listed in October 2026. The fifth is the southwest corner around Willow Pond Way, which is in the city but in the Grafton School District.

Port Washington has more variety than most small Wisconsin cities. The 2020-2024 American Community Survey counts 5,691 housing units (plus or minus 304). Of those, 3,058, about 54%, are single-family detached and 432 are attached single-family homes such as townhouses. The rest are in two-flats and small and mid-size buildings: 694 in buildings of 5 to 9 units, 345 in buildings of 10 to 19, and 389 in buildings of 20 to 49. Of the 5,572 occupied homes, 3,665, about 66%, are owner-occupied, a lower share than the surrounding towns.

The age mix spans the city's whole history. The ACS counts 939 homes built before 1940, about 16% of the stock, most of them near downtown and on the north side. The 1970s were the biggest decade, at 926 homes, followed by 783 from the 1960s. Building has continued: 614 homes from the 2000s, 569 from the 2010s and 129 from 2020 or later. The city's median home was built in 1975, against 1978 for Ozaukee County.

The ACS puts the median owner-occupied home value at $296,300 (plus or minus $19,124). Its value table shows a thin top: 295 owner homes valued at $500,000 to $749,999, 53 at $750,000 to $999,999 and 7 at $2 million or more, the last with a margin of error larger than the estimate. That matches what the listings show. Port Washington is a city where $1 million buys the top of the local market.

Each age band brings its own checklist. A pre-1940 house near downtown can have old wiring, plaster and a fieldstone or block foundation. A 1960s or 1970s ranch is usually due for windows, a roof and mechanicals. A condo near the harbor needs a review of the association's reserves and rules. A house near the bluff needs a look at the slope behind it, which the shoreland section covers.

Port Washington is not a $2 million market inside the city limits, and I would say that up front to anyone shopping the top of Lake Michigan's Wisconsin shore. On October 5, 2026, a public Port Washington search page showed 68 active or pending listings. None was priced at $2 million or more. The highest was $1,395,000.

The city's lake-view tier is concentrated in two places. At Prairie's Edge on the south lakefront, a two-bedroom, 2,072-square-foot ranch on Shieling Lane, with a 2027 build date, was listed at $1,395,000, about $673 a square foot. Its listing calls it the last lot in the development with direct, expansive views east to the lake, on a lot of about 5,200 square feet. Nine condominium units on Bastle Wynd in the same development were listed from $865,000 to $915,000, with four bedrooms and about 2,500 to 2,900 square feet, and a unit on Shieling Lane was listed at $935,000.

Downtown, by the harbor, condos run a little lower. On the same day, a two-bedroom of 2,296 square feet on East Washington Street was listed at $879,900, a two-bedroom of 1,415 square feet on North Lake Street at $769,900, and a two-bedroom of 2,411 square feet on East Pier Street at $725,000.

The true Lake Michigan lakefront, a house on its own bluff with acreage and a path to the beach, is mostly outside the city. The two highest lakefront listings with a Port Washington address on October 5, 2026, $1,250,000 for a 1991 house on 2.2 acres with about 170 feet of frontage and $1,200,000 (pending) for a 2022 house with 140 feet of frontage on 1.66 acres, were both in the Town of Port Washington. The Town of Port Washington guide covers that tier.

Zillow's top-tier index for ZIP 53074, which tracks the upper third of homes in the city and town together, was $547,860 in August 2026, up 6.1% in a year. For Lake Michigan property above $2 million within an hour of Milwaukee, buyers usually look farther south at Mequon, River Hills or Fox Point.

Port Washington is the lower-priced end of Ozaukee County. Zillow's typical home value for the city was $392,624 in August 2026, up 5.8% from $371,185 a year earlier and about 11.1% over two years. For comparison, Zillow's index for Ozaukee County as a whole was $507,273, Mequon was $659,897, Cedarburg $566,235 and Grafton $460,062. Only Saukville, at $410,038, and Port Washington sat close to $400,000 among the county's larger places.

Sales are steady for a city this size. Redfin's monthly data counts 157 sales in Port Washington in the 12 months through May 2026, up from 141 the year before. Monthly medians ranged from $290,000 to $500,000. In April 2026 the median was $406,000 on 19 sales; in May it was $425,000 on 19 sales, with a median of 39 days on market and homes selling at about 100.7% of list price.

Those numbers describe a market where well-priced houses sell in about five to seven weeks and often at or a little above the asking price. Sale-to-list ratios were above 100% in about half of the last 12 months. The exceptions are the top listings, which take longer, because the pool of buyers at $800,000 and up is small in a city where the median sale is near $400,000.

Zillow and Redfin measure different things. Zillow estimates the value of every home; Redfin reports what actually closed. In a month with seven sales, as in January 2026, one lake-view sale can push the median to $500,000. I'd read the trend from the 12-month count and the index, and price any specific house from the closest comparable sales. If you're running numbers on a purchase, my guide to how much house you can afford in 2026 is a good place to start.

Wisconsin property tax vocabulary is different from Illinois, so start with the translation. The local assessor sets an assessed value. The Department of Revenue sets a full, or equalized, value for the whole city each year. The ratio between them is the assessment level, and the tax rate, quoted in dollars per $1,000, applies to the assessed value.

Port Washington's assessments are close to market. The DOR's 2025 report puts the city's assessment level at 0.96, and Ozaukee County's 2025 rate sheet gives the ratio as 0.9646. So an assessed value is typically about 96% of market value.

The county sheet lists two rates for the city. In the Port Washington-Saukville School District, which covers almost all of the city, the 2025 net rate is $13.64 per $1,000 of assessed value, after the state school levy credit, with a lottery credit of $188.97 and a first dollar credit of $62.99. In the small Grafton School District area, the net rate is $12.86, with credits of $168.55 and $56.18. Of the $13.64, the city's own municipal levy is about $5.75 and the school levy about $7.26; the county and the technical college make up the rest. The DOR's citywide effective rate on full value is 1.315%.

A worked example. On a $392,600 house, Zillow's typical value, the assessed value would be about $378,700. In the Port Washington-Saukville area, the 2025 bill would be about $5,167, or about $4,915 after both credits for a primary residence, roughly 1.25% of price. The same house in the Grafton district area would be about $4,645 after credits. On one of the $935,000 Prairie's Edge condos, the bill would be about $12,305 before credits. Coming from Lake County, Illinois, the tax bill is usually the first number compared, and a rate near 1.3% of value is in the same range many Lake County suburbs pay.

The DOR's lottery credit report confirms that credit is for a primary residence only, so a second home pays the higher figure. The DOR lists three tax incremental districts in the city in 2025: its full value is $1,900,925,500 with them and $1,817,620,400 without. Wisconsin's real estate transfer fee is $0.30 per $100 of value, normally paid by the seller. Assessments trail sales, so budget off the rate times your price. This is general information, not tax advice; your bill depends on your parcel, your credits and the assessor.

On Lake Michigan, the question is not pier rules. It is the bluff. Wikipedia describes the city's coastline north and south of downtown as clay bluffs 80 to 130 feet high, cut by ravines, with gravel and sand beaches below. Clay bluffs erode, and the rate depends on lake levels, storms, drainage and what the owner and neighbors have built.

Ozaukee County's own rules show how seriously the county treats this. Chapter 19 of the county code, dated March 4, 2026, says the county's coast consists almost entirely of steep bluffs and ravines with a high recession rate. In the unincorporated towns, it requires new buildings and septic systems in the bluff area to be set back the greater of 75 feet from the bluff edge or a stable-slope line of 2.5 feet horizontal for every foot of bluff height, measured from the toe of the bluff by an engineer or surveyor. Small accessory structures can be no closer than 40 feet.

That county chapter applies to unincorporated shoreland. Inside the city, the City of Port Washington's own zoning code and the state's rules for cities govern, so the city's planning and building staff are the office to call about a bluff-top addition, a new deck or a stairway to the beach. I'd ask for any geotechnical report, any past bluff stabilization work and the permit history before buying a house near the edge. The county rule is still a useful benchmark for how much setback a careful buyer should want.

The data center deal also touches the bluff. The Ozaukee Press reported on August 13, 2025 that the city's $175 million TIF district for the project can be used for bluff stabilization among other items.

Because Lake Michigan homes on a bluff can't have a pier, the marina is how most owners here keep a boat. The Port Washington Marina has 220 slips for boats of 30 to 50 feet, with fuel, a pump-out station, a fish cleaning station, showers and laundry, and it is a Wisconsin certified clean marina. Wikipedia gives the season as April 1 through November 1.

Fishing is the harbor's other identity. Wikipedia notes that anglers fish the breakwaters for lake trout and Chinook salmon, and that a Great Lakes sport fishing derby runs in early July. Sailboat races start from the harbor through the summer.

Offshore, the Wisconsin Shipwreck Coast National Marine Sanctuary, designated in 2021, covers about 962 square miles of Lake Michigan off Ozaukee, Sheboygan, Manitowoc and Kewaunee counties and names Port Washington as one of its principal cities. At designation it included 36 known shipwrecks dating from the 1830s to 1930.

For a buyer comparing lake towns, the practical points are slip availability and cost, which change each season, and the drive from the house to the harbor. I'd confirm the current slip rates and any waiting list directly with the marina office before counting on a slip.

Inside the city, homes are on city water and sewer. Port Washington draws its water from Lake Michigan through a city treatment plant, and the data center project has put that system in the news. The Ozaukee Press reported on August 13, 2025 that the $175 million TIF district can pay for extending water and sewer to the campus and for a possible expansion of the water and wastewater plants, and that the campus could use up to 1.2 million gallons a day on the hottest days. When I look at a house here, I'd ask for the last year of utility bills and whether any special assessments are pending, which in Wisconsin can be added to the tax bill.

Fire and ambulance service come from the Port Washington Fire Department. The Town of Port Washington noted on February 4, 2026 that the city has moved from an all-volunteer department to a full-time professional one, citing rising 911 and ambulance calls. The same department serves the surrounding town under contract.

Port Washington is also the county seat, so the county courthouse, register of deeds and land records office are in town. That makes it easy to pull a deed, a survey or a plat in person.

Almost all of the city is in the Port Washington-Saukville School District, a unified K-12 district. That is simpler than the K-8 and union high school split many Wisconsin lake towns have. Dunwiddie Elementary, K4 through 4, enrolled 324." Lincoln Elementary, K4 through 4, enrolled 302." Thomas Jefferson Middle School, grades 5 through 8, enrolled 677." Port Washington High School enrolled 809." The district enrolled 2,415 in all.

Wikipedia says Lincoln serves the northern and eastern parts of the city and Dunwiddie the southern and western parts, and both feed Thomas Jefferson Middle and Port Washington High. The district also runs Saukville Elementary for the western parts of the town and Saukville.

The southwest corner of the city, around Willow Pond Way, is in the Grafton School District. Grafton High School enrolled 727.

Assignment follows the parcel and the district's attendance lines, not the mailing address. The district line also changes the tax rate by about 78 cents per $1,000, so confirm both with the district and the tax bill.

I-43 runs along the city's west and north sides, with Exit 100 at the north edge. Highway 32 runs north-south through the city, and Highway 33 comes in from the west and ends downtown.

I ran free-flow routes on the OSRM routing engine, which uses OpenStreetMap roads and no traffic, from downtown on October 5, 2026. Treat these as best-case estimates. Downtown Milwaukee is about 27 road miles and 37 minutes. Milwaukee's airport is about 33 miles and 47 minutes. Cedarburg is about 9 miles and 17 minutes, and Sheboygan about 28 miles and 35 minutes north.

The Illinois numbers are the honest part. Vernon Hills is about 87 miles and 108 minutes in free-flow traffic. Downtown Chicago is about 113 miles and 140 minutes, and O'Hare about 110 miles, with the router giving 151 minutes. That puts Port Washington past the 90-minute line from Lake County, Illinois. For a Lake County, Illinois buyer, it works as a Milwaukee-area home or a summer place with a harbor, not as a daily drive south.

Port Washington has no passenger train; the Union Pacific runs freight only. The closest train to Chicago is Amtrak's Hiawatha from the Milwaukee Intermodal Station, about 26 road miles and 36 minutes from downtown Port Washington in free-flow traffic.

I counted trains in Amtrak's published schedule feed for the week of October 6, 2026. It showed six Milwaukee-to-Chicago trains on weekdays, the first at 7:15 a.m., and five on Sundays. The schedule that week gave 99 minutes from Milwaukee to Chicago Union Station on most trains and 112 on the first one, longer than the Hiawatha's usual time, so check the current timetable.

For Milwaukee, Wikipedia describes a weekday commuter bus, Route 143, the "Ozaukee County Express," from a stop near I-43 Exit 96 in Saukville to Milwaukee, and a county shared-ride taxi that must be booked ahead. I'd confirm current schedules with the transit agencies before relying on either.

Put plainly, a Port Washington to Chicago Loop trip by car and train is well over two hours each way. It is a workable occasional trip and not a daily commute.

Wikipedia counts 29 city parks, with picnic shelters, ball fields, tennis courts, nature preserves and a public pool. The city's lakefront is the main draw: beaches below the bluffs, the breakwater and the marina walk.

The Ozaukee Interurban Trail, a paved rail trail of about 40 miles on the old Milwaukee-to-Sheboygan interurban line, runs north-south through the city. It links Port Washington with Grafton, Cedarburg and Mequon to the south and Belgium to the north, and connects to Milwaukee County's Oak Leaf Trail at Brown Deer. The trail's official opening celebration was held in Port Washington in 2002.

Just south of the city, Lion's Den Gorge Nature Preserve is a 73-acre county park with about 0.7 miles of Lake Michigan frontage, more than 1.5 miles of trails and views from bluffs nearly 100 feet high. Harrington Beach State Park, Ozaukee County's only state park, is about 13 minutes north in the Town of Belgium.

The two lighthouses are open to visitors in different ways: the 1860 light station as a museum run by the historical society, and the breakwater light as a walk out along the north breakwater. Wikipedia also describes Fish Day, billed as the world's largest one-day outdoor fish fry, held on the third Saturday in July since 1964 as a charity fundraiser, along with a summer arts festival and sport fishing contests.

The biggest change in Ozaukee County is on Port Washington's north side. In January 2025, the city and the Town of Port Washington agreed to let the city annex about 1,900 acres of town farmland between the city's north border and Dixie Road, west of I-43 and east of the Interurban Trail. On May 20, 2025, WPR reported, the council annexed about a third of that land and zoned it as a technology campus district, and city officials projected the project would nearly double the city's tax base.

Vantage Data Centers broke ground on the Lighthouse campus on December 17, 2025. The Ozaukee Press reported a $15 billion project on 675 acres of former farmland along Highland Drive: four data center buildings totaling about 2.5 million square feet, 1.3 gigawatts of power, about 4,000 construction workers and about 1,000 permanent jobs. On September 24, 2026, Construction Review Online reported the campus was about 20% to 25% complete, with 2,800 to 3,000 workers on site daily and phased handover expected at the end of 2027.

The money flows through a TIF district. WPR reported on August 8, 2025 that Vantage would front about $175 million for water, sewer, roads, a water tower and power infrastructure and be repaid from the district's new taxes over up to 20 years. The Ozaukee Press reported the city's estimate of a $170 reduction in 2027 on a $350,000 home; that is a projection, not a bill.

Power is the open question. On August 7, 2026, Wisconsin Watch reported that the state Public Service Commission made American Transmission Company restart its application for the lines and five substations to serve the campus, a project of more than $1.3 billion across four counties. The Ozaukee Press reported on September 16, 2026 that ATC refiled with a new preferred route, that review could take about a year, and that construction would take about 17 months after approval. For any house near a proposed route, I'd read the filed route maps before writing an offer.

Downtown is changing on a smaller scale. The Ozaukee Press reported that Pier Street Landing, a four-story building with 51 apartments and two ground-floor commercial spaces on a parking lot between Washington and Pier streets, broke ground on August 12, 2026, with $2.6 million in downtown TIF help and occupancy planned for fall 2027.

The Port Washington Police Department provides police service in the city, and the Port Washington Fire Department provides fire and ambulance service. I don't characterize the safety of any town or neighborhood. Anyone who wants the data can ask the police department or look up its reported figures on the FBI Crime Data Explorer.
