Of 37,567 homes in Orland Township, 37,115 got a higher assessment in 2026 than their final 2025 value: 98.8%. Only 268 stayed the same and 184 went down. Of the eleven south and west suburban townships whose 2026 notices we have measured, none had a larger share of homes go up, though Stickney (98.7%) and Lemont (98.6%) were close behind. Orland's Assessor appeal window runs from September 24 to November 6, 2026.
How big the increases were
The typical home rose 19.9%, from a median assessed value of $32,000 to $38,000. But the spread is wide, and almost half of all homes rose by more than 20%:
| Change, 2025 final to 2026 notice | Homes | Share |
|---|---|---|
| Went down | 184 | 0.5% |
| Unchanged | 268 | 0.7% |
| Up 10% or less | 4,140 | 11.0% |
| Up more than 10%, up to 20% | 14,574 | 38.8% |
| Up more than 20%, up to 30% | 11,296 | 30.1% |
| Up more than 30%, up to 50% | 6,543 | 17.4% |
| Up more than 50% | 562 | 1.5% |
That is 18,401 homes, 49.0%, up by more than 20%, and 7,105, 18.9%, up by more than 30%.

The few Orland Township homes with Palos Park addresses are too few to report on their own.
By type of home
The Assessor classifies every home by type and size. The increase ran through all of them, but not evenly:
| Home type (Assessor class) | Homes | Went up | Median change |
|---|---|---|---|
| Two-story or more, under 63 years, 3,801–4,999 sq ft (2-08) | 889 | 99.9% | +29.2% |
| Condominium (2-99) | 8,682 | 100% | +28.6% |
| Two-story or more, under 63 years, 2,001–3,800 sq ft (2-78) | 7,674 | 99.9% | +20.0% |
| One-story, over 1,800 sq ft (2-04) | 4,160 | 99.7% | +18.9% |
| Two-story or more, under 63 years, up to 2,000 sq ft (2-07) | 573 | 99.7% | +16.7% |
| One-story, 1,000–1,800 sq ft (2-03) | 3,010 | 99.1% | +16.0% |
| Split-level (2-34) | 6,253 | 99.6% | +15.8% |
| Townhome or row house, under 63 years (2-95) | 4,554 | 95.0% | +12.5% |
| One-story, under 1,000 sq ft (2-02) | 666 | 92.0% | +10.0% |
Every one of Orland's 8,682 condominium units got a higher assessment, and the typical condo rose 28.6%, second only to the largest newer two-story homes and well above the township's 19.9%. Townhomes rose the least, and they account for most of the homes that went down: 130 of the 184.
Neighborhood by neighborhood
The Assessor values homes by neighborhood. In each of Orland's 27 neighborhoods with at least 50 homes, at least 96.4% of homes went up. The typical increase ranged from +15.0% in the lowest neighborhood to +33.9% in the highest. This was a township-wide reassessment, not a few areas pulling the average.
What a township-wide increase means for your bill
When nearly every home goes up, the tax bill does not go up by the same percentage. The taxing districts' levies are divided over a larger total value, so the tax rate falls. What moves your bill is how your increase compares with everyone else's. A condo that rose 29% in a township that rose 20% will carry a larger share of the same levy; a home that rose 10% will carry a smaller one.
That is also why an appeal is about comparison. The strongest residential argument in Cook County is that your home is assessed higher than similar homes nearby. If your notice rose faster than the homes around you, that is the case to make.
