If you’ve been house-hunting on Madison’s East Side lately, you’ve probably seen some listings that look like a typo. A three-bedroom ranch with a huge yard for a price that actually feels reachable? Mature trees, quiet streets, but the taxes are surprisingly low?
Welcome to the urban islands of Blooming Grove.
Whether you're looking at April Hills, Rambling Acres, or the Gallagher Plat, you aren't just buying a house; you’re buying a ticket into a historic municipal vanishing act. On October 31, 2027, the Town of Blooming Grove officially dissolves and becomes part of the City of Madison.
As of January 2026, we have officially entered the final phase of this transition. Here is the ground-level reality of what’s changing while you’re out there touring homes this weekend.
Building Permits
The most immediate change happened just a few days ago. As of January 1, 2026, the Town of Blooming Grove stopped issuing its own building permits.
If you buy a fixer-upper in Blooming Grove today and want to finish the basement or add a deck, you won't be heading to the Town Hall on Stoughton Road. You’ll be dealing directly with the City of Madison Building Inspection Division.
The Insider Take: This is actually a good thing for buyers. It means any work you do this year will already be up to Madison’s code standards, so there won’t be any surprises when the final merger happens in 2027.
Exploiting the Tax Gap
Let’s talk about math, because this is one of the primary reasons why people buy here. For the tax year starting now in 2026, the difference in mill rates—the amount you pay per $1,000 of value—is significant.
Based on current estimates, a Blooming Grove resident in the McFarland school district might pay a mill rate around 13.12, while a City of Madison resident in Madison schools is looking at closer to 24.19.
The Breakdown: On a $450,000 home, that’s a difference of nearly $5,000 a year.
If you were to buy in Blooming Grove today, you are essentially getting a $400-a-month discount on your mortgage payment for the next two years. For a first-time buyer, that is huge—it helps you qualify for a better home or keeps your debt-to-income ratio in a much safer zone.
But a word of caution: That discount expires on November 1, 2027. When your 2028 tax bill arrives, that savings will vanish as your property is assessed at City rates.
The Water Utility Trap
This is the one thing most agents miss. Many Blooming Grove homes are still on private wells and septic systems.
When the final attachment happens in 2027, the City of Madison doesn't mess around. If there is a city water or sewer main in the street in front of your house, you will likely be required to connect.
The Cost: Between special assessments and hiring a plumber to run the lines to your house, this can easily be a $15,000 to $25,000 expense.
The Pro Move: Look at the street during your tour. Do you see fire hydrants? If yes, the city main is there. If the house has a well, you need to factor that future connection cost into your offer price.
If You Are Buying
Don't be afraid of the Blooming Grove name. Use the current service confusion to your advantage. Most buyers are looking for turnkey Madison, which means these island homes often sit on the market a few days longer. If you can handle the future tax jump and you’ve verified the water status, you can snag a lot more house for your money here than you can in nearby neighborhoods like Atwood or Eastmorland.
If You Already Own Here
You’ve enjoyed the lower taxes for years, but the party is almost over. If you’re thinking about selling, 2027 is your golden window. Once the transition is complete, your home officially becomes City of Madison, which opens you up to a much larger pool of buyers who were previously scared off by the Town status. Marketing your home as newly incorporated Madison could lead to a nice equity bump.
The Final Timeline
Now (Jan 2026): City of Madison handles all building permits and inspections. Dec 2026: Your last full Town tax bill arrives. Oct 31, 2027: The Town of Blooming Grove officially dissolves at midnight. Nov 1, 2027: You are officially a City of Madison resident. Services like police and trash switch over. Dec 2027: Your first full City tax bill arrives, payable in 2028.
At the end of the day, the neighborhoods of Blooming Grove are in a strange but exciting limbo. For the next two years, you get to live in a town that is effectively sunsetting into one of the most desirable cities in the Midwest. Whether you are moving in to take advantage of the temporary tax break or you are a long-term resident preparing for the city services to arrive, the key is to stay ahead of the paperwork and the utility requirements. These urban islands have a lot of character and, once the transition is complete, they will likely be some of the most stable and sought-after pockets of the East Side. If you want to dive deeper into the specific attachment maps or need a recommendation for a local contractor who knows the city's new permit system, let’s grab coffee and talk through your options.
