What Should a Cook County Board of Review Appeal Brief Include?

A Cook County Board of Review appeal brief should identify the property, explain the current assessment and requested relief, state the appeal grounds, and connect each important fact to supporting evidence. The brief is not a place to repeat every document. Its job is to help the reviewer understand the property, the argument, and the requested assessed value without reconstructing the case from scattered attachments.

Under Cook County Board of Review Rule 14, the brief should address the property’s nature and use, assessment history, requested relief, facts, valuation methods, legal basis, and conclusion. Commercial, industrial, income-producing, and larger residential matters can require more detail than a straightforward residential filing.

What should the opening of the appeal brief say?

The opening should give the reviewer the essential answer in a few sentences: which parcel or parcels are involved, how the property is used, the current assessment, the requested assessment, and the main reason for the change. If the claim concerns both overvaluation and lack of uniformity, say so clearly and distinguish the evidence supporting each ground.

Avoid beginning with a general complaint about rising taxes. A high bill may motivate the appeal, but the Board decides the assessed value. The brief should focus on the property facts and valuation evidence the Board can evaluate.

How should the property be described?

Describe the property’s actual use, physical improvements, land, location, and material condition as of the relevant valuation date. Include facts that affect the analysis, such as building size, age, class, units, occupancy, parking, renovations, deferred maintenance, or a recent demolition. For multiple PINs, explain how the parcels function together.

The description should match the parcel record, photographs, appraisal, income statements, and other exhibits. If official records contain an error, identify the incorrect field, state the accurate fact, and attach reliable proof rather than quietly using a different number elsewhere in the submission.

What assessment history belongs in the brief?

State the current assessed value and any relevant prior value, including a recent decision that explains why the assessment changed. The history should be concise and tied to the present request. It is useful when it shows a reassessment, a corrected characteristic, a changed property condition, or another event that matters to value.

Assessment history is context, not proof that the current value is wrong. The brief still needs evidence for the requested assessment in the year under review.

How do you state the requested relief?

Give a specific requested assessed value and, when useful, the corresponding market-value conclusion. Explain the calculation. For example, a residential uniformity analysis should show how the comparable assessments lead to the requested level. An income approach should show the income, expenses, capitalization rate, and resulting value rather than offering only the final number.

Do not confuse assessed value with the amount of the tax bill. Cook County assessments are one input in the final tax calculation. The appeal should request an assessment supported by the evidence, not a desired tax-bill reduction.

How should comparable properties be explained?

A comparison table is useful only when the brief explains why the properties are comparable. Identify meaningful similarities and differences in location, class, use, style, size, age, condition, units, land, and other value factors. If an adjustment or judgment is necessary, explain it plainly.

A long list of lower assessments can be less persuasive than a smaller, well-supported set. Exclude properties chosen only because they produce the desired answer. The comparison should be reproducible from the attached records.

How should commercial valuation evidence be summarized?

For an income-producing property, summarize the relevant income and expenses, occupancy, rents, and capitalization analysis. Identify the period covered by the financial statements and reconcile unusual items. If the appeal relies on a sale or appraisal, explain why it reflects the valuation date and disclose the information required by the Board’s rules.

The brief should direct the reviewer to the important exhibits rather than bury the conclusion in a full appraisal or spreadsheet. Cite the exhibit or page that supports each central figure.

What legal or procedural points belong in the brief?

Use legal authorities only when they materially support the appeal ground or requested treatment. The brief should also identify procedural facts that matter, such as ownership, representation, parcel relationships, a recent sale, a prior appraisal, or evidence required for a specialized claim. Do not assume the reviewer will infer compliance from the attachments.

Rule citations should be accurate and restrained. A clear factual and valuation explanation usually matters more than pages of generic legal language.

What common mistakes weaken an appeal brief?

Common problems include an unexplained requested assessment, inconsistent building areas or income figures, comparables with no similarity analysis, attachments that are not identified, and a focus on the tax bill instead of assessed value. Other problems include using the wrong assessment year, omitting a related PIN, or relying on facts that do not match the valuation date.

A final quality-control review should test whether every major factual statement has support, whether every exhibit has a purpose, and whether the conclusion follows from the evidence presented.

When should an owner seek help?

An owner may want legal or valuation help when the property is income-producing, has multiple PINs, has conflicting records, requires specialized evidence, or involves a substantial requested change. A review can also help identify which appeal theory is strongest and which documents are actually necessary.
