The question in this post’s title now has an answer with data behind it. The 2025 north suburban reassessment has run its full course, appeals included. So the commercial real estate appraisal Chicago owners bring to the table matters more than it did a cycle ago. Here is the short version. Values went up, appeal reductions got smaller, and the Assessor’s office is actively defending its numbers. The owners who did best brought evidence. The ones who brought complaints paid retail.
- The 2025 north suburban results, from the Assessor’s own releases.
- Why commercial appeal reductions shrank from 20% to 14%, and what that signals.
- What to do now, since the 2025 values are landing on 2026 bills.
What the 2025 North Suburban Numbers Show
Start with the scale. The Assessor’s April 2025 release on Evanston Township reported total assessed value growing 28%. That reflects three years of market change since the 2022 cycle. Then came the appeals, and the Assessor’s wrap-up on the 2025 cycle tells the rest. Take the 13 north and northwest suburban townships together. Homeowners’ share of the tax base moved from 66% before reassessment to 68% after appeals. In 2022, that shift ran from 63% to 67%, roughly twice as large.
The commercial side explains the difference. Board of Review appeals reduced commercial values 14% in the 2025 cycle, down from 20% in 2022. So the burden still shifted toward homeowners, but less, because commercial reductions got harder to win.
The Appeal Climate Tightened
Two details from the Assessor’s release show why. First, the office defended 14 large commercial properties through the appeal process, mostly data centers. Four received no reduction at all, and four more received reductions under 25%. Second, a December 2024 report found north suburban industrial properties typically assessed at two-thirds of market value after appeals. That is exactly the kind of finding that invites tougher defense of commercial values. Put plainly, the easy reduction era is fading. The data center defense also fits the wider 2026 picture, where high-growth niches attract both capital and assessor attention. A class the market prices confidently is a class the county values confidently, and defends the same way. Owners of ordinary buildings inherit that posture whether they like it or not. We tracked the same pattern countywide in our BOR data breakdown. In short: record appeal volume, rising scrutiny, and outcomes that follow the evidence.
The Commercial Real Estate Appraisal Chicago Owners Actually Need
In that climate, the appraisal stops being paperwork and becomes the case. A mass-model assessment can still mismatch a specific building. For example: real vacancy the model ignored, capital needs it never saw, income the market will not support. Still, nobody at the Board takes that argument on faith anymore. Instead, the winning file documents it: rent rolls, comparable sales, and a traceable income analysis. We detailed that discipline in NOI and cap rates under scrutiny. For portfolio owners, a preliminary review screens which parcels carry a real gap. Then the full workup goes only where it pays. The complete playbook lives in our commercial tax appeal guide.
Bills Arrive Now, and the Next Cycle Is Dated
The timing is not abstract. Properties certified in the 2025 reassessment affect second-installment bills issued in 2026. So north suburban owners are meeting these numbers in their mailboxes this year. Meanwhile, the calendar keeps moving. Appeal windows open township by township every year, even between reassessments. Chicago gets revalued in 2027, and the north suburbs come around again in 2028. For example, the evidence file built for a 2026 appeal meets the 2028 notice already standing. The work compounds in the owner’s favor for once.
Translate the tightening into dollars on one building. Say a north suburban property hoped for the old 20% reduction on a $2 million assessed value, a $400,000 trim. At the 2025 cycle’s 14% average, the same appeal yields $280,000 instead. That $120,000 difference stays in the assessed base. Then the equalizer and the local rate multiply it on every bill until something changes. The lesson is not that appeals stopped working. It is that average outcomes got thinner. So the above-average file, the one with documented income and defensible comps, is where the remaining money lives.
Hold the Value Up Before Someone Tests It
The 2025 cycle delivered a clear message to commercial owners north of the city. Assessments rose with three years of market change, and reductions tightened. Also, the office that sets the values now defends them with data. So match the method. Get the building’s real numbers documented, test them against what the assessment implies, and file where the gap is real. A value that holds up is no longer a nice-to-have. It is the price of being taken seriously in the room.

Frequently Asked Questions
What happened in the 2025 north suburban reassessment?
The 13 north and northwest suburban townships were revalued for the first time since 2022. Evanston Township’s total assessed value grew 28%. After Board of Review appeals, homeowners’ share of the tax base went from 66% to 68%. That is about half the shift seen in the 2022 cycle.
Why did commercial appeal reductions shrink?
Per the Assessor’s release, Board of Review appeals cut commercial values 14% in 2025 versus 20% in 2022. Also, the office actively defended large commercial values through the process. Whatever the mix of causes, the practical effect is the same. Winning a reduction takes stronger evidence than it used to.
When do the 2025 values show up on tax bills?
Properties certified in the 2025 reassessment affect second-installment bills issued in 2026. So the financial impact of the cycle lands this year, which is why owners comparing their bill to their building’s real performance are doing it now.
Can north suburban owners still appeal before 2028?
Yes. Appeal windows open township by township every year, even between reassessments. They run first at the Assessor and then at the Board of Review. An appeal corrects one year’s value, so owners with a persistent gap often file annually until the next cycle resets the number.
When is the next reassessment for the north suburbs?
2028, under the county’s three-year rotation. Chicago is revalued in 2027 and the south suburbs in 2026. Evidence gathered for a current appeal keeps working at the next notice. So the file is worth building once and maintaining.
Commercial Values Built for a Tougher Room
PahRoo Appraisal & Consultancy has valued Chicago-area commercial property for over two decades. An appraiser holding both MAI and SRA designations leads the firm. Maybe your 2026 bill needs testing against a commercial appraisal of what the building actually earns. Maybe a dispute calls for litigation-ready work with testimony behind it. Either way, the value arrives documented, because the 2025 cycle showed what happens to numbers that are not.
