About the community
A settled 1970s Lake Zurich neighborhood with a park and a school inside it.
Old Mill Grove is an established single-family neighborhood on the east side of Lake Zurich, developed by U.S. Home Corporation and built out from roughly 1969 into the mid-1970s. It is a mature, tree-lined community of split-levels, tri-levels, raised ranches, and two-story colonials, with no gate and no homeowners association. Two things make it stand out: a village-owned park of the same name sits inside the neighborhood, and Sarah Adams Elementary is located on Old Mill Grove itself, all within the well-regarded Lake Zurich District 95.

What it’s actually like to live here
Old Mill Grove trades curb-appeal flash for practical value. The streets are mature and shaded, the lots are generous by suburban standards, and the housing is honest 1970s stock that gives first-time and move-up buyers a foothold in one of Lake County's most sought-after school districts without paying new-construction prices. A village park sits inside the neighborhood, elementary-age kids may walk to a school on the same road, and the village lakefront, library, and recreation programs are all a short drive away.
The tradeoffs are the ones you would expect from a half-century-old subdivision. Homes are aging, so roofs, mechanicals, windows, and kitchens vary a lot from house to house, and buyers should budget for updates on original-owner properties and read inspections carefully. Floor plans reflect their era, with the compartmentalized layouts of splits and tri-levels rather than open-concept great rooms, though many owners have modernized their interiors over the years.
The other honest caveat is the Lake County tax load and the commute geometry. Property taxes here run high by national standards, which buyers weigh against the home price and the schools. Because there is no train in town, rail commuters drive to Barrington to catch the UP Northwest line, while drivers lean on Routes 12 and 22, which carry real rush-hour traffic. For households that value schools, space, and an inside-the-neighborhood park over a walk-to-train lifestyle, the balance tends to land in Old Mill Grove's favor.
The questions buyers actually ask
Old Mill Grove FAQ
The questions I get most from buyers shopping Old Mill Grove. If yours isn't here, text 224-385-8779, same-day reply.
- What are property taxes like?
- Roughly $8,000 – $15,000 per year, depending on home size and value. Lake County assessor records are the source of truth. Happy to pull a specific bill on any home you're considering.
- What's the typical closing timeline?
- 30 to 60 days from accepted offer to keys. Cash deals can close in two weeks. Conventional financing is usually closer to 60.
- Is there an HOA in Old Mill Grove?
- No. There is no mandatory homeowners association and no monthly dues on record, so buyers do not pay HOA fees and there is no covenant-based architectural review tied to the neighborhood.
- What school district serves Old Mill Grove?
- Lake Zurich Community Unit School District 95. Sarah Adams Elementary sits right in the neighborhood on Old Mill Grove, and Lake Zurich High School serves the district. Confirm your specific elementary and middle school assignment on the District 95 boundary map, since boundaries can change.
- When were the homes built and what styles are they?
- The neighborhood was developed by U.S. Home Corporation and built out from roughly 1969 into the mid-1970s. Expect split-levels, tri-levels, raised ranches, and two-story colonials, generally 3 to 5 bedrooms, with condition varying between original-owner homes and updated remodels.
- What does a home here cost and how is the market?
- Old Mill Grove is generally attainable for the Lake Zurich area rather than a luxury pocket, and well-updated homes tend to draw strong interest. For current asking prices, recent sales, and how fast homes are moving, check the live Market snapshot on this page, which pulls directly from the MLS.
- How do people commute to Chicago from here?
- There is no Metra stop in Lake Zurich, so most rail commuters drive to the Barrington station on the Union Pacific Northwest line into Ogilvie Transportation Center downtown. Drivers use Routes 12 and 22 for the northwest suburbs and toward I-90.
- Are property taxes high?
- Lake County carries relatively high effective property tax rates, generally in the low-2 percent range of market value before homeowner exemptions. Always verify the current tax bill for a specific property with the Lake County Treasurer, since it depends on assessed value and exemptions.

Your local agent
Joe knows Old Mill Grove
Most agents will list anything. I focus on the places I actually know, and the things that move value here don't show up in the MLS write-up: which streets and buildings hold demand, what the HOA or assessments really cover, how the comps read once you account for condition and location, and where buyers consistently want to be.
When you're ready to tour or list, you want someone who has read the last 50 closed comps in this specific market, not a national average, and can tell you what they actually mean for your price. That's how I work. Text or call any time, and I'll give you a real take, not a brochure.
