TO THE COOK COUNTY BOARD OF REVIEW — 2026 RESIDENTIAL UNIFORMITY APPEAL BRIEF

Subject Property: 5107 W ADAMS ST, CHICAGO, IL 60644
Permanent Index Number (PIN): 16-16-206-009-0000
Township: West Chicago Township (Code 77) | Assessor Neighborhood Code: 77080 | Property Class: 2-03

1. BASIS OF APPEAL: LACK OF UNIFORMITY (ILLINOIS CONSTITUTION ART. IX, SEC. 4)
The Subject Property is a Class 2-03 residential parcel (built 1953, Masonry construction) containing 1,210 square feet of building area on a 5,353 square foot lot in West Chicago Township, Assessor Neighborhood 77080.
Its improvement (building) is currently assessed at $11,135, or $9.20 per square foot of building area ($19,700 Total Assessed Value).

2. COMPARABLE UNIFORMITY EVIDENCE IN ASSESSOR NEIGHBORHOOD 77080
A review of comparable Class 2-03 residential properties in the identical Assessor Neighborhood (77080) demonstrates that the Subject Property is assessed substantially above similar neighboring homes:
• PIN 16-16-206-003-0000 (5133 W ADAMS ST): Class 2-03, 1,406 sq ft (Frame, Slab bsmt) — Building AV $9,364 ($6.66 / sq ft)
• PIN 16-16-206-010-0000 (5101 W ADAMS ST): Class 2-03, 1,484 sq ft (Frame, Slab bsmt) — Building AV $10,564 ($7.12 / sq ft)
• PIN 16-16-206-014-0000 (5118 W QUINCY ST 2E): Class 2-03, 1,065 sq ft (Frame, Slab bsmt) — Building AV $7,803 ($7.33 / sq ft)
• PIN 16-16-206-013-0000 (5122 W QUINCY ST): Class 2-03, 1,029 sq ft (Frame, Slab bsmt) — Building AV $7,803 ($7.58 / sq ft)
• PIN 16-16-206-007-0000 (5115 W ADAMS ST): Class 2-03, 1,599 sq ft (Masonry, Full bsmt) — Building AV $12,335 ($7.71 / sq ft)

3. REQUESTED RELIEF
The median building assessment of the comparable Class 2-03 properties above is $7.33 per square foot. Applying $7.33 per square foot to the Subject Property's 1,210 square feet yields a uniform Building Assessed Value of $8,869. Added to the uncontested Land Assessed Value of $8,565, the Petitioner respectfully requests that the Total Assessed Value be reduced from $19,700 to $17,434 (an assessment reduction of $2,266, or 11.5%).
