Commercial Property Assessment Evidence and Disclosure in Alberta

1. Freeze the governing dates and documents

Save the assessment notice, complaint form, filing confirmation, assessor correspondence, Notice of Hearing and current procedural directions. Record the assessment year, valuation date, condition date and every filing, disclosure and rebuttal deadline in one control sheet.

Do not rely on a generic online calendar when the notice or board direction gives the controlling date. Assign responsibility and proof of delivery for every required submission.

2. Map evidence to the filed grounds

Create a separate row for every complaint issue: the assessor's input or conclusion, the owner's position, the requested correction, supporting exhibits and anticipated respondent evidence. This prevents a large file from obscuring the actual decision the board is asked to make.

Do not use disclosure to introduce a matter omitted from the complaint form. If the filed grounds are unclear or incomplete, obtain qualified advice about available procedural options before the deadline expires.

3. Verify the physical and legal property facts

Reconcile site and building area, age, use, quality, condition, occupancy, access, parking, improvements and construction status to plans, permits, photographs, measurements and other reliable records. Identify which facts existed on the property-condition date.

Use title, legal description, zoning or land-use records and approved permits carefully. Legal ownership, permitted use, existing operation and redevelopment potential answer different questions.

4. Reconcile income evidence

For income-model issues, organize leases, amendments, rent roll, occupancy, arrears, recoveries, operating statements and capital items by period. Distinguish contract results from the typical market inputs used in a mass-appraisal model.

Show each calculation and source. Explain exclusions, normalization and whether a cost is recoverable, recurring, owner-specific or capital. Do not substitute a spreadsheet conclusion for the underlying records.

• Rent and area
• Vacancy and credit loss
• Recoveries
• Operating expenses
• Capitalization inputs
• Applicable market period

5. Select comparable evidence deliberately

Explain why each sale, assessment or property is comparable and identify differences in location, use, size, age, condition, tenancy, rights conveyed, transaction date and other material factors. Include the source record rather than a hyperlink alone when the board requires the actual information.

Separate valuation arguments from equity arguments. Comparable assessments may inform equity; market transactions may inform valuation. State the purpose for which each comparison is offered.

6. Source every exhibit

Give each exhibit a stable number, title, source, date obtained, relevant period and page count. Preserve original documents and produce a clean working copy without changing their substance.

For photographs, maps and tables, identify the property, viewpoint, date and author or source. For expert material, include the professional's identity, assignment, qualifications, report and any required attendance or authorization.

7. Protect confidentiality within a public process

Calgary advises that ARB hearings are public and filed evidence becomes part of the public record. Review leases, financial records, personal information and proprietary material before filing, and follow the board's current procedure for any confidentiality request or redaction.

Do not remove information needed to understand the evidence or apply unsupported redactions. Legal and privacy advice may be required where disclosure duties and confidentiality obligations conflict.

8. Meet format and delivery requirements

Use the board's accepted portal, email, mail or in-person process as applicable. Calgary directs parties to use readable, page-numbered documents without passwords or security restrictions and notes that hyperlinks alone are not evidence.

After submission, verify receipt, completeness and access. Retain the uploaded file set, confirmation, timestamp and checksum or version identifier so the hearing team knows exactly what the board and respondent received.

9. Use rebuttal to answer, not rebuild

Review the respondent's disclosure immediately. Index each response against the original grounds and identify genuine new evidence, disputed facts, calculation differences and matters that require clarification.

Rebuttal should respond within the permitted scope and deadline. Do not hold essential primary evidence back for rebuttal or use it as a second opportunity to advance a case that was not properly disclosed.

10. Preserve the complete decision record

Keep the complaint, all party disclosures, procedural correspondence, hearing notes, settlement or withdrawal documents, written decision and any corrected roll or fee refund. Alberta's decision databases can help identify prior reasoning, but each case is decided independently.

Carry verified property corrections and recurring assessment inputs into the next year's review. Keep appraisal, assessment-agent, legal and brokerage work products labelled by their actual purpose so later users do not rely on them outside scope.
