What it's like to own in Northville
Beyond the tax rate, three things shape what owning in Northville actually costs: the age of the homes, what the water utility reports at the tap, and what local air testing has turned up. Each figure below carries the date of the survey it came from.
Lead in drinking water

90th percentile for Northville · below Michigan's 12 ppb action level. Sampled at the fifth liter, which deliberately draws water that sat in the service line and reads higher by design — not comparable to systems that sample standard.

Lead is measured at the water system, not the house — it cannot tell you whether a specific property has a lead service line. Radon is a ZIP-level test distribution, not a prediction for any one home; the EPA recommends testing every home regardless. Screening information only.
Common questions
What is the property tax rate in Northville, Michigan?
Northville is taxed at 42.1693 mills for a homestead (principal residence) under the official 2025 Michigan Department of Treasury millage report. On a $350,000 home at the uncapped taxable value that is about $7,380 a year.
Does the tax rate change by address within Northville?
No. All of Northville sits in Northville Public School District, so the millage is 42.1693 at every address in the municipality. Your bill still changes after you buy, because it is recalculated on the uncapped taxable value rather than the seller's capped one.
How much are property taxes on a $350,000 home in Northville?
About $7,380 a year at the homestead rate. Michigan taxes the taxable value, not the sale price, and after a sale that value uncaps to roughly half what you paid — so $350,000 is taxed on about $175,000.
Why is the tax bill on a Northville listing lower than what I would pay?
Because the figure on the listing is the seller's. Michigan caps annual taxable-value growth while an owner keeps the property, and that cap is removed the year after it sells. The longer the seller owned it, the further their bill sits below yours.
How does Northville compare with the rest of Wayne County?
It is the 11 lowest of 43 municipalities in Wayne County and 173 of 236 across the eight-county region — 7.91 mills below the county median.
