What is the AACI designation, and why do lenders ask for it?

AACI stands for Accredited Appraiser Canadian Institute. It is the designation the Appraisal Institute of Canada grants to appraisers qualified to value all types of real property, from a farm to an office tower. If a lender, lawyer or court has told you the appraisal "has to be done by an AACI", this is what they mean, and this guide explains what the letters cover, how they differ from the CRA designation, what they cost you as a client, and how to check them in two minutes.

What does AACI stand for?

Accredited Appraiser Canadian Institute. The Appraisal Institute of Canada (AIC), the national professional body for real property appraisers, grants two designations. The AACI is the senior one. In the Institute's own words, AACI members are "qualified to offer valuation and consulting services and expertise for all types of real property." The letters after the name, P.App, stand for Professional Appraiser, the title the Institute attaches to both of its designations.

AACI vs CRA: what is the difference?

The Institute's other designation is the CRA, Canadian Residential Appraiser. A CRA is qualified to appraise "dwellings containing not more than four self-contained family housing units" and individual residential sites. That covers houses, condominiums, duplexes, triplexes and fourplexes. It does not cover a plaza, a warehouse, an office building, a farm, development land or an apartment building of five or more units. Those are AACI work.

Why do lenders and lawyers ask for an AACI?

Three reasons. First, scope: a commercial property is outside the CRA designation, so within the Institute only an AACI can take the assignment competently, and CUSPAP requires an appraiser to have the competence before accepting work. Second, standards: every AACI report must comply with CUSPAP, the Canadian Uniform Standards of Professional Appraisal Practice, which fixes what a report must contain, how value is reasoned and what the appraiser must disclose. A lender's credit committee or a judge can read an AACI report knowing what framework produced it. Third, accountability: the designation can be lost. The Institute runs a professional practice and complaint process, which gives the people relying on the report somewhere to go if it is wrong, and designated members carry professional liability insurance through the Institute's mandatory program.

What is CUSPAP?

The Canadian Uniform Standards of Professional Appraisal Practice, published by the Appraisal Institute of Canada. The Institute states that compliance is compulsory for every professional services assignment its members take on. The current edition, CUSPAP 2026, took effect on April 1, 2026 and applies to any assignment completed on or after that date. It is organised into nine parts, including ethics, reporting, real property appraisal, review and consulting, each with rules that set minimum requirements and comments that explain them. When an Aion report says "CUSPAP-compliant", this is the document it refers to.

What does an AACI appraisal involve?

The same things a lender's underwriter will look for. A defined purpose and intended users. An effective date of value. A site visit with photographs, unless the assignment specifically waives it. Zoning and highest-and-best-use analysis. Market evidence: comparable sales, market rents, vacancy and capitalisation rates. The valuation approaches that fit the property, usually the income approach for a leased building, cross-checked by direct comparison, with the cost approach added for new or special-purpose buildings. A reconciliation into one final value. And the assumptions and limiting conditions the value depends on. At Aion, a second AACI reviews every draft before it is signed; the full sequence is on our how it works page.

How much does an AACI appraisal cost?

There is no set fee for the designation itself; the fee depends on the property type, size, income complexity and the purpose of the report, and is quoted in writing before any work starts. What the designation changes is what you can do with the report. A commercial report without an AACI signature is, for financing, court or a tax appeal, usually a report you will have to pay for twice.

How long does an AACI appraisal take?

At Aion, a commercial report is usually delivered 5–10 business days after the site visit. Complex properties, portfolios and retrospective valuations can take longer. Rush service may be available for financing deadlines.

How do you verify that an appraiser holds the AACI?

Search the Appraisal Institute of Canada's Find an Appraiser directory by name or city. A designated member appears with the designation beside the name. If a report says "AACI" and the directory does not, ask before relying on it. Aion's reports are signed by Ashita Chandra, AACI, P.App, Director of Valuations, or another AACI-designated appraiser on the team.

The standard every member must follow on every assignment, CUSPAP, is explained in our guide to CUSPAP.

When don't you need an AACI?

For a house, a condominium or a building of up to four units bought or refinanced through a lender, a CRA is the right designation and usually the more economical one. For an informal idea of what a commercial property might list for, a broker's opinion of value is free, though no lender will accept it. The AACI is for the moments when a number has to hold up: financing, a purchase or sale between unrelated parties, a tax appeal, an estate, an expropriation or a dispute.
