Home / Lake County / Beach Park
We looked at every Beach Park home in Lake County's own records and compared each one with the homes most like it nearby. Of those, 6.7 percent are assessed higher per square foot than every single one of those neighbors, and that's the situation where an Illinois appeal actually has a case.
That's pretty close to Lake County as a whole, where the figure is 6 percent. Put the other way round, about 93 out of every 100 Beach Park homes we could compare sit at or below somebody similar nearby, and for those an appeal on this argument honestly isn't going to work.
So for Cook County we publish how many appeals actually won, because the Assessor there publishes every case. Lake County doesn't publish its appeal outcomes in any form we can read, and we'd rather show you a number we've measured than one we've made up. The share above is the next best thing: it's the board's own test, run on every home we could fairly compare.
Beach Park is split across more than one township, and that really matters, because Lake County publishes assessments one township at a time and your 30 days to appeal start from your own township's date. So two neighbors in Beach Park can have different deadlines. Here's how Beach Park's homes split:
And your township is printed on your assessment notice, so go by that rather than the name of the town.
| Township | Values published | Last day to file |
|---|---|---|
| Benton | 7/23/2026 | 8/24/2026 (closed) |
| Waukegan | 8/6/2026 | 9/8/2026 (closed) |
| Newport | 9/3/2026 | 10/5/2026 (closed) |

Now, Illinois decides these on fairness between neighbors rather than on what your house would sell for. You show at least three homes genuinely like yours, nearby, that are assessed lower per square foot than yours is. By similar we mean the same size within about 15 percent, built within about 15 years, and the same quality grade, condition, stories, bathrooms, basement and garage, because a board will pick apart a comparison that skips those. The bar's also higher than people expect, because Illinois wants clear and convincing evidence on this argument.
And before you file, Lake County's Board of Review suggests talking to your township assessor first. It doesn't cost anything, and an assessor who agrees can fix it without a hearing. If you do file, the board wants its own forms, filed through its SmartFile system, within 30 days of your township's publication date. That date's printed on your assessment notice.
Honestly, for most people here the answer is no. The only real question is whether your home is one of the 6.7 percent sitting above every similar neighbor. Our free check runs exactly that comparison for your address, using Lake County's own records, and tells you straight which side you're on.

Every number here comes from Lake County's public parcel layer, which carries each home's building assessment, living area, year built, assessment neighborhood and its features. For each home we found the others in the same assessment neighborhood that match it on all of the features above, and counted it only if it had at least three. A home counts as above every similar neighbor when its building assessment per square foot is higher than all of theirs. We only publish a town with at least 150 homes we could compare.
One thing worth knowing when you compare towns: a home with only three lookalike neighbors has an easier time sitting above all of them than a home with twenty. So towns with more varied homes, like large-lot or custom-built areas, tend to show a higher share. That's still true for the people who live there, but it doesn't mean their assessor is less fair than anyone else's.
