Assessment Request for Information

Assessment regularly mails requests for information to the owners of non-residential and multi-residential properties to produce fair and equitable assessments in accordance with the Municipal Government Act (MGA) and associated regulations. Assessment reviews and updates information on an ongoing basis. Accurate and up-to-date data ensures that properties are being assessed fairly.

Why does Assessment request information from property owners?


The City of Calgary regularly requests detailed property and business information to prepare market value assessments. This information is collected at various times throughout the year. It is used to get up-to-date physical information about that property including size, as well as market information such as recent lease information. Requests are also sent for sales information or tax status.

The information you provide in the Assessment Request for Information (ARFI) is very important as it helps us prepare fair and equitable market value assessments to accurately capture market changes in your property assessment since last year. By providing your ARFI, you help us prepare reliable preliminary property assessments that we can discuss with you during the Pre-Roll Consultation Period (Pre-Roll) in the fall.

During Pre-Roll, non-residential and multi-residential property owners and their representatives can review their preliminary Property Assessment value before they are finalized and mailed in January. This interaction often brings more certainty as you plan for the coming year.

Non-residential property owners (or their authorized property managers) can provide their information online by logging into Assessment Search, which is a secure-access site that requires owners to register for a City myID account. Step-by-step instructions on how to set up your account, check your property details, and review sales, are available in the Assessment Search How-to guide for property owners.

Do I have to respond to an Assessment Request for Information?


Assessment Requests for Information are made in accordance with the MGA including section 295(1) which states that ‘A person must provide, on request by an assessor, any information necessary for the assessor to carry out the duties and responsibilities of an assessor under Parts 9 to 12 and the regulations.’ Section 295(4) of the legislation further states that, ‘No person may make a complaint in the year following the assessment year under section 460 or, in the case of designated industrial linear property, under section 492(1) about an assessment if the person has failed to provide the information any information requested under subsection (1) within 60 days from the date of the request.

Information sent previously or that was provided in connection with a tribunal hearing does not relieve the assessed person of the obligation to provide the information requested.

Please note that once collected, the information will only be further disclosed in accordance with section 33(c) of the Freedom of Information and Protection of Privacy Act (FOIP) and the Municipal Government Act (MGA).​​​​

We are committed to providing reliable information and service that you can count on.
