Buying a Home in Wauwatosa, WI: Tosa Village, the River Parks and the New Building Near Mayfair

Seen from above, the curving streets of Washington Highlands are supposed to trace the outline of a Prussian helmet. Milwaukee's public radio station took the story up in 2019 as a rumor that just won't die. The district's own 1989 nomination to the National Register of Historic Places is less patient with it. A Tosa Connection history column cites the form and calls the helmet story "most likely bunk."

I'm Jeff Moran, NMLS #483943, licensed to originate in Wisconsin through C2 Financial Corporation, and I have been in the mortgage business since 1996. I work from Bluffton, South Carolina, and I put this page together from public records and local reporting for clients looking at a home in Wauwatosa. Wauwatosa is a Milwaukee County city of about 48,000 people on the Menomonee River, with a downtown on its first mill site, several National Register residential districts, and the Milwaukee Regional Medical Center on the old County Grounds. The four-county picture, from Milwaukee's Polish flats out to Lake Country, is on the Milwaukee area page. This page stays inside the Wauwatosa city limits, and the research behind it was done on November 5, 2026.

Washington Highlands and its curving streets

Washington Highlands began on a brewer's farm. The planning firm Hegemann & Peets laid it out starting in 1916, and the Wisconsin Historical Society's record calls it the first large subdivision in Milwaukee County. If you're looking at a home between N. 60th and N. 68th streets, from W. Lloyd Street up to Milwaukee Avenue, you'll find Colonial Revival, Tudor Revival and Spanish Revival homes along those curves. The whole neighborhood is on the National Register of Historic Places and is a Wauwatosa Landmark as well.

Tosa Village, on the old Hart's Mills site

Wauwatosa started out as Hart's Mills. Charles Hart settled on the Menomonee River in 1835, and the city's own history says his mills gave the settlement its first name. The historic downtown, Tosa Village, grew up on that mill site at Harwood Avenue and State Street. Hart Park and the river parkway are right beside it, the Harmonee Bridge carries you over the river into it, and parking along State Street and Harwood Avenue is free.

Around here the city goes by Tosa. The city says the full name honors a Potawatomi chief, Wauwautaesie, and the Wisconsin Historical Society says the word's meaning "is a mystery."

If you end up near the Village, the Tosa Farmers Market is right there on Saturday mornings from early June to late October. It sets up in the Hart Mills parking lot at 7720 Harwood Ave. Urban Milwaukee's season preview counted 2026 as its 17th year. Every September the Village also hosts TosaFest, a street festival that has been going since 1976.

In April 2026 the council approved city financing terms for a three-story building at 7746 Menomonee River Parkway, with 10 one-bedroom apartments and four townhomes behind it, the Milwaukee Journal Sentinel reported.

Tosa's oldest homes and its historic districts

The Wisconsin Historical Society's record names the Lowell Damon House, at 2107 N. Wauwatosa Ave., as the oldest building still standing in the city. Oliver Damon began it in the 1840s. It is a private home today, and the Wauwatosa Historical Society says a permanent preservation easement protects it.

That stretch of Wauwatosa Avenue is its own National Register district, with Tudor Revival homes and bungalows from 1844 to 1927. If you'd like to see more of them on foot, the city's Historic Preservation Commission publishes a self-guided tour called Walking Wauwatosa, covering Arts and Crafts, bungalow and mail-order homes. If the home you're considering is in Washington Highlands, in one of these districts or is a local landmark, I'd ask the city's planning office what that means for exterior work before you plan any.

Hart Park, Hoyt Park and the trails along the Menomonee

On summer Wednesdays, Hart Park's Rotary Performance Pavilion at 68th and State streets hosts Tosa Tonight, free concerts at 6 p.m. Milwaukee Record's lineup had the 2026 season running June 17 through August 12. The Wauwatosa Curling Club has been in the park since 1925, and its home, the Muellner Building, was renovated in 2024 and also houses the Senior Center.

Farther along the river, Hoyt Park at 1800 N. Swan Blvd. is home to The TOSA Pool. The old 1939 pool closed in 2003, and a nonprofit, Friends of Hoyt Park & Pool, formed to bring it back. OnMilwaukee's story on the pool says the new pool opened in 2011, and The Landing beer garden was added two years later to help pay for it.

The Wisconsin DNR's trail page says the Hank Aaron State Trail runs west from Lakeshore State Park in Milwaukee, through the Menomonee Valley, and ends at Underwood Parkway in Wauwatosa, where it meets the county's Oak Leaf Trail. The Oak Leaf follows the Menomonee and turns right through Hoyt Park. On the Fourth of July, FOX6 calls the city's parade one of the largest in the state. It has run for more than 90 years, mostly along North Avenue, though the route changes from year to year.

The County Grounds and the medical center

The County Grounds are Milwaukee County's own land inside Wauwatosa. They started as a county poor farm, with an asylum that opened in 1880. Today they hold the Milwaukee Regional Medical Center, Milwaukee County Research Park, the UWM Innovation Campus, and flood basins built by the Milwaukee Metropolitan Sewerage District (MMSD), the regional sewer district that also handles flood control.

Architect Alexander Eschweiler designed four buildings for a county farm school in 1911 and 1912, and HGA's project page says the Echelon Apartments, built in 2016, restored his administration building as their clubhouse. A local group, Friends of the Monarch Trail, won a no-build zone around those buildings for the monarch butterflies that stop over there.

The Milwaukee area page covers the medical campus and the CONNECT 1 bus line that runs to it from downtown. If you're looking at a home near the campus, you'll see Froedtert's nine-story patient tower is going up at the hospital's main entrance, at N. 92nd St. and W. Doyne Ave., and it is projected for winter 2027. The Daily Reporter covered the plans when Froedtert announced them in 2024.

In the Research Park, the former eight-story Sonesta hotel at 10499 Innovation Drive is now the Waterfair Apartments, 146 units that BizTimes calls affordable, and Irgens' Viridia, with 204 apartments, is the last piece of that firm's work there. In January 2026 the council also set up a tax incremental district to support more housing in the park. That arrangement lets the new property tax from development there help pay back the public cost of it.

Scheels, new apartments and the building around Mayfair

Mayfair has been a shopping center since 1958, and the land around it is changing. Scheels plans a 210,000-square-foot store on the former Boston Store site, set to open in spring 2027 with more than 500 jobs, and BizTimes reported that the land deal closed in December 2025. The council has also approved Barrett Lo Visionary Development's plan for about 918 apartments around the mall, built in three phases over 10 to 12 years. On N. Mayfair Road, a 92-apartment building won city financing in April 2026, with construction expected to run into July 2027.

North Avenue and the Zoo Interchange

North Avenue carries two of Tosa's business districts. East Tosa runs sixteen blocks between Wauwatosa Avenue and 60th Street, and MidTown Tosa is about 50 businesses, mostly between 80th Street and Swan Boulevard. The avenue was rebuilt from Mayfair Road to Met-to-Wee Lane in 2023.

Next, the city and the Wisconsin Department of Transportation plan to replace the North Avenue bridges over the Menomonee and redesign the avenue between Met-to-Wee Lane and Wauwatosa Avenue, with construction scheduled for 2028 and 2029. If you're looking at a home along that part of North Avenue, the city's North Avenue project page posts each update. On the freeway side, the state finished rebuilding the Zoo Interchange in late 2023, and FOX6 reported that the last piece widened I-41/US 45 to eight lanes from Swan Boulevard to Burleigh Street.

Wauwatosa schools and the 2024 referenda

Wauwatosa School District voters passed two referenda in November 2024, and the district's referendum page explains both. The first lets the district raise $16.1 million a year above its state revenue limit, the cap Wisconsin puts on what a district can collect for day-to-day operating costs, for the 2025-26 through 2028-29 school years. The second is $60 million of building work, mostly overdue repairs at Eisenhower, Madison, Roosevelt, Jefferson and Washington elementaries and Wauwatosa Montessori/Fisher, plus accessibility work that includes East and West high schools.

Both referenda are part of what you'll see on a Wauwatosa tax bill, and the city assessor's estimator includes their 2025 effect. An earlier $124.9 million building referendum passed in 2018, and that work is finished.

Confirming the home is inside the City of Wauwatosa

The City of Milwaukee borders Wauwatosa on the east and north, West Allis on the south, and Brookfield and Elm Grove on the west, across the Milwaukee-Waukesha county line. I'd confirm from the tax bill or the city assessor's records that a home is inside the City of Wauwatosa, rather than going by its ZIP code or mailing address. The Waukesha County line on the west side is also a property tax line, and the Milwaukee area page goes through what that means.

A Wauwatosa tax bill after the 2025 revaluation

Wauwatosa revalued every home in the city in 2025. The city assessor's revaluation page says the average home went from an assessment of $274,100 in 2024 to $418,800, an average increase of 44.7%. Each home's tax goes up or down depending on how its own change compares with that average. The assessor's estimator also includes the 2025 effect of the 2024 school referenda.

A 2024 assessment on a listing, or a tax bill from before the revaluation, measures the home on the old scale. The 2024 tax rates were set on those old values too, so they can't be applied to a new assessment. The city's property tax page shows the lines on a Wauwatosa bill: the City of Wauwatosa, the Wauwatosa School District, Milwaukee County, MMSD and Milwaukee Area Technical College, less the state credits. For your payment estimate, I'll use the most recent bill on the specific home, issued after the revaluation.

Wauwatosa's water comes from Lake Michigan by way of Milwaukee

The Wauwatosa Water Utility's page says it started in 1897 on well water. Since a 1963 agreement with Milwaukee Water Works, it has bought treated Lake Michigan water from Milwaukee, and in 2024 it pumped an average of 3.93 million gallons a day.

The lead service line program described on the Milwaukee area page belongs to the City of Milwaukee. A Wauwatosa home is served by the Wauwatosa Water Utility, so that is the office I'd ask whether the line from the main to the home is lead, and whether the city offers any help replacing it. I'd ask the same office about the sewer lateral, the private pipe that runs from the home to the city sewer.

Hart Park was rebuilt to hold the Menomonee

After the floods of 1997 and 1998, more than 60 homes and more than a dozen businesses in the Menomonee floodplain were bought and demolished. MMSD's Hart Park page says its $48 million project then lowered the ground to store floodwater and grew the park from 20 acres to 50, with a levee and a floodwall.

On the County Grounds, MMSD's page on the basins says they cover about 65 acres and hold about 315 million gallons. A half-mile tunnel diverts Underwood Creek into them and lets the water back out slowly to the Menomonee.

The storm of August 9 and 10, 2025 tested all of it. Wauwatosa police took more than 500 calls about flooded basements, blocked storm drains and standing water, and Hart Park closed for cleanup. WISN reported that engineers credited the MMSD projects with lessening the damage. For a home near the Menomonee River, Underwood Creek or Honey Creek, I'd look at the FEMA flood map and the city's draft floodplain layer for Underwood Creek. I'd also read the seller's answers about water in the basement on the Real Estate Condition Report.

Putting a Wauwatosa home into a mortgage payment

The payment a lender qualifies you on includes the property tax and the homeowners insurance. On a Wauwatosa home, that means the bill issued after the 2025 revaluation and an insurance quote for the specific address, plus flood coverage if the home needs it. The loan limits in the box below this page are Milwaukee County's for 2026. The conforming limit for a single-family home is $832,750, and the FHA limit is $541,287, the lowest limit HUD sets anywhere in the country.

FHA loans in Wisconsin and VA loans in Wisconsin cover how each program works here. Pre-approval in Wisconsin covers what your letter is based on, and the Wisconsin page covers the rest of the state's rules. If you already own a home in Wauwatosa and are thinking about your rate or your equity, refinancing in Wisconsin is a good place to start.

You can see your rate options for a Wauwatosa purchase whenever you're ready, and choose the option that works best for you. If you'd rather talk it through with me first, I'm happy to take your call.

Nothing here is a loan approval, a denial or a commitment to lend, and it is not tax advice. The assessed value of a specific home and the credits on its bill are set by the City of Wauwatosa and the county treasurer, so please confirm them with those offices.

Common questions

Is Washington Highlands shaped like a Prussian helmet?

The helmet is a long-running Wauwatosa story. A local history column citing the district's 1989 National Register nomination calls it "most likely bunk." Washington Highlands was planned by Hegemann & Peets from 1916 on a former brewer's farm, and the Wisconsin Historical Society calls it the first large subdivision in Milwaukee County.

Does a Wauwatosa ZIP code mean the home is in the City of Wauwatosa?

Not on its own. Wauwatosa borders the City of Milwaukee on the east and north, so I'd confirm from the tax bill or the Wauwatosa assessor's records that a home is inside the city limits before comparing its taxes or its water service.

Why did Wauwatosa assessments go up so much in 2025?

The City of Wauwatosa revalued every home in 2025, and the assessor reports an average increase of 44.7%. A home's tax goes up or down depending on how its own change compares with that average, so a bill or assessment from before 2025 is on a different scale.

Where does Wauwatosa get its water?

The Wauwatosa Water Utility has bought treated Lake Michigan water from Milwaukee Water Works since a 1963 agreement. Before that it ran on well water, starting in 1897. The utility is the office to ask about the service line to a specific home.

How do I check whether a Wauwatosa home is in a floodplain?

You can look up the address on the FEMA flood map, and for a home near Underwood Creek, the city's draft floodplain layer as well. MMSD's work at Hart Park and the County Grounds basins was built to hold Menomonee and Underwood Creek floodwater, and the seller's Real Estate Condition Report covers water in the basement.

What does "Tosa" mean in Wauwatosa?

Tosa is the city's own short name, used for TosaFest, Tosa Tonight, Tosa Village and The TOSA Pool. The city says the full name honors a Potawatomi chief, Wauwautaesie, while the Wisconsin Historical Society calls the word's meaning a mystery.
