The controlling distinction

Method follows property group.

Calgary's annual assessment is mass appraisal for property taxation. The City uses income, sales-comparison and cost methods differently across property groups—and sometimes within one group. The correct starting point is the actual City classification, property record and 2026 Assessment Explanation Supplement, not a generic commercial formula.

01 / Comparison

What the City says it models.

The table preserves current City labels and points to the official property-type record. It does not calculate an assessment.

Property-type pages describe mass-appraisal structure. The property's current myTax record, Assessment Explanation Supplement and any owner-requested section 299 or 300 information remain the subject-specific municipal evidence.

02 / Model-to-file reconciliation

Test the classification
before the conclusion.

Industrial / Sales comparison; cost for defined properties

Industrial property

The City states that industrial properties are typically assessed through sales comparison. It uses cost for unique or purpose-built properties or where market data is limited, and may use underlying land value where vacant-land value exceeds improved-property value.

City-identified variables: Assessable area · Finished area · Land use · Location · Outbuildings · Site coverage · Tenancy · Year of construction

Owner evidence: Assessable and finished areas · Land-use designation and exact location · Site coverage, outbuildings and tenancy · Construction year, physical condition and functional utility

Boundary: The City's industrial categories and variables are mass-appraisal records. They do not establish a current sale adjustment, replacement-cost conclusion or the value of business equipment.

Office / Income; sales or cost for defined subgroups

Office property

The City typically applies an income approach using typical market rent, vacancy, expenses and capitalization rates. It identifies sales comparison for office condominiums and house conversions, and cost for partially completed office properties and data centres.

City-identified variables: Location · Physical condition · Functionality · Construction year · Net rentable area · Floor plate · Storeys · Space mix · Parking · Land area

Owner evidence: Correct City office category and space-type mix · Net rentable area, floor plates and storeys · Executed leases, vacancy and operating statements · Parking, amenities, exposure, condition and construction quality

Boundary: Typical assessment income is not automatically contract rent, effective rent after inducements, collected income or buyer-underwritten NOI. Office categories must remain distinct.

Retail / Income; sales or cost for defined subgroups

Retail property

The City typically assesses retail through an income approach using typical rent, vacancy, operating costs and capitalization rates for fee-simple modelling. It identifies sales comparison for retail condominiums, cost for some unique purpose-built properties, and underlying land value where it exceeds the improved-property indication.

City-identified variables: Subproperty type · Trade-area location · Typical rent · Vacancy · Operating costs · Capitalization rate · Space types · Land value

Owner evidence: Retail subproperty type and district · Space types, areas, exposure, access and parking · Rent roll, executed leases and recoveries · Vacancy, operating costs, condition and land contribution

Boundary: The City models the fee-simple estate using typical parameters. That record must not be presented as a tenant's contract economics, brokerage asking rent or investment-market conclusion.

Multi-residential — four or more units on one title / Income approach — gross income multiplier

Multi-residential property

The City applies a gross income multiplier derived from market analysis to typical market rent and vacancy. It obtains rental evidence annually through the Assessment Request for Information process and separates this group from titled condominium property.

City-identified variables: Property type · Multi-residential zone · Core or non-core · Mixed use · Unit count · Quality · Suite type · Occupancy

Owner evidence: Legal title and City structure category · Unit count, suite type, quality and occupancy · Actual rent roll and vacancy record · Mixed commercial space and core/non-core location

Boundary: The City's GIM model is an assessment methodology, not a universal apartment transaction multiple. Actual income, typical rent, financing and capital requirements remain separate records.

Land / Sales comparison

Vacant non-residential land

The City assesses vacant non-residential land by comparison with sold properties. Its published record identifies location, parcel size, land use and property-specific influences as value factors.

City-identified variables: Location · Parcel size · Land use · Environmental influence · Servicing · Topography

Owner evidence: Legal parcel and verified site area · Current land-use designation · Servicing, access and topography · Environmental, physical and off-site influences

Boundary: A vacant-land assessment does not establish planning entitlement, development feasibility, residual land value, timing or a current buyer's price.

Accommodation / Income approach — property-specific three-year stabilization

Hotels and motels

The City requests hotel and motel income and expense data annually and stabilizes three years of performance using a 50/30/20 weighting. It normalizes typical expenses and removes the stated business interest before capitalizing net income to real estate.

City-identified variables: Location group · Accommodation subtype · Revenue sources · Normalized expenses · Three-year weighting · Business-interest adjustment · Capitalization

Owner evidence: Three years of complete revenue and expense records · Correct motel, limited-service or full-service grouping · Accommodation, office, retail, parking and pad-site space · Business, FF&E, management and real-estate allocations

Boundary: A hotel transaction can include real estate, operations, brand, management, FF&E and other rights. The assessment allocation does not determine a contemplated transaction allocation.

Specialized property / Cost approach with sales-derived land

Recreational and institutional property

The City typically uses a cost approach for recreational and institutional property because these assets can be unique, purpose-built or have limited comparable market data. Published methodology adds land to improvement cost and subtracts depreciation; land rates are developed through sales comparison.

City-identified variables: Land value · Construction-cost record · Depreciation · Property use · Purpose-built improvements · Physical and functional condition

Owner evidence: Exact use, ownership interest and exemption context · Building inventory, age, area and construction · Condition, depreciation and functional obsolescence · Land area, comparable land record and property restrictions

Boundary: Municipal cost modelling is not a current replacement-cost estimate, insurable value, appraisal or evidence that every improvement contributes its cost to market value.

03 / Owner evidence sequence

Three records
before a response.

01

Confirm the subject record

Reconcile the roll number, legal interest, City property group, areas, space mix, construction, condition, land use and tenancy to current source documents. A category mismatch changes which model evidence is relevant.

02

Request the model explanation

Calgary states that eligible owners or authorized agents can request an Assessment Explanation Supplement for the subject and up to five comparable properties, plus defined additional information. Use the current myTax or formal AIR instructions.

03

Separate assessment from market strategy

Typical assessment income, municipal land value and depreciated cost are not asking price, buyer underwriting or an appraisal. A current sale or lease decision needs present property evidence and current market alternatives.
