Lyons Township Property Tax Appeal 2026: $59K Avg Savings, Highest in South Triad

Lyons Township has the highest average per-property savings potential of any township in Cook County's south and west suburban reassessment triad. TaxRival's analysis has flagged 28 commercial properties with an average estimated savings of $59,526 per year and a total savings opportunity of approximately $1.7 million.

Those numbers are driven by the township's larger commercial properties — properties where a gap between assessed value and market value translates to tens of thousands of dollars in annual over-taxation. For owners of these properties, the 2026 reassessment is the most consequential tax event in a three-year cycle.

Municipalities in Lyons Township

Lyons Township covers a broad stretch of western Cook County, encompassing communities with very different commercial profiles:

• La Grange — an established western suburb with a walkable downtown commercial district and additional commercial development along major corridors
• Brookfield — home to Brookfield Zoo and surrounding commercial development along Ogden Avenue and other arterials
• Western Springs — a primarily residential community with a small, concentrated commercial district
• Indian Head Park — a small community along the Stevenson Expressway (I-55) with limited commercial development
• Hodgkins — an industrial and logistics hub along I-55 with significant warehouse and distribution properties
• McCook — a heavily industrial community with quarry operations, waste management facilities, and other industrial uses

This diversity is key to understanding the township's appeal data. The high average savings figure is not driven by Main Street storefronts in La Grange — it is driven by larger industrial and commercial properties in Hodgkins, McCook, and along the I-55 corridor where individual assessed values can be substantial.

Why the Average Savings Are So High

At $59,526 per year, Lyons Township's average per-property savings is roughly five times the south triad average. Several factors explain this:

• Large industrial properties in Hodgkins and McCook: These communities contain major warehouse, distribution, and industrial facilities. A single large industrial property might carry an assessed value in the millions, and even a modest percentage reduction generates a large dollar savings.
• Higher-value commercial properties along I-55: The Stevenson Expressway corridor attracts commercial development with higher property values than older, more established commercial strips in other townships.
• Mixed retail and commercial in La Grange and Brookfield: While individually smaller, the commercial properties in these communities contribute to the overall pool, and some carry assessments that exceed what their income and comparable sales data support.

The concentration of larger properties also means that a smaller number of owners account for a disproportionate share of the total savings. If you own one of these larger properties, the urgency of a well-prepared appeal cannot be overstated.

Analysis Results

TaxRival's review of Lyons Township commercial properties produced the following results:

• 28 properties flagged for potential appeal
• $59,526 average estimated annual savings per property
• $1.7 million total estimated savings across all flagged properties

These estimates are based on a comparison of current assessed values to market indicators including comparable sales, income capitalization benchmarks, and per-square-foot assessment ratios for the relevant property types and locations. Properties were flagged when one or more indicators suggested the current assessment exceeds fair market value by a material margin.

The 2026 Reassessment

Lyons Township is part of the 2026 south and west suburbs reassessment. All commercial properties in the township will receive new proposed assessed values from the CCAO, replacing the values set during the 2023 reassessment.

The 2026 cycle comes with updated appeal rules that are especially important for the types of properties common in Lyons Township. The loaded capitalization rate methodology, which incorporates property taxes into the cap rate used to convert income to value, directly affects how the Assessor values income-producing industrial and commercial properties. For large industrial properties in Hodgkins and McCook where property taxes represent a significant operating expense, the loaded cap rate can materially change the math of what constitutes a fair assessment.

Documentation standards have also tightened. The CCAO now requires dated color photographs, formatted income and expense statements, and specific evidence presentations. For larger properties where the appeal involves complex valuation arguments, the quality and completeness of the submission is critical. Our guide to reducing commercial property taxes covers the requirements in detail.

Preparing a High-Value Appeal

For properties with five-figure savings potential, appeal preparation should be comprehensive:

• Professional-quality photographs: Dated, color photos of all areas of the property. For large industrial properties, include drone or aerial shots if available, along with interior photos showing ceiling heights, loading areas, office build-out (or lack thereof), and any deferred maintenance.
• Detailed income and expense statements: Three or more years of operating data with granular detail. For multi-tenant properties, include rent rolls with lease terms, escalation schedules, and vacancy history.
• Comparable sales: Recent transactions involving similar property types. For large industrial properties, the comparable search may need to extend beyond the immediate township to find relevant transactions of similar scale.
• Functional obsolescence documentation: For older industrial buildings, document any features that reduce the property's competitiveness — low clear heights, insufficient power, limited dock configurations, outdated sprinkler or HVAC systems.
• Cap rate analysis: Calculate the cap rate implied by your current assessment and compare it to market cap rates from actual sales of similar properties. This is one of the most effective arguments for income-producing properties.
