Property Assessments

Requests for Information have been mailed to property owners located in the 2025 re-inspection zone. The 2025 re-inspection cycle will begin on March 1. Click here to see what areas are being re-inspected in 2025.

You can expect that a County Assessor will visit your property to perform an inspection at some time in a 5 year cycle. The purpose of these inspections is to ensure all assessment records are accurate and current so a correct Assessment can be developed.

Property assessment is the process of assigning a dollar value to a property for taxation purposes. This value, known as the assessed value, determines the amount of property tax owed by the owner. This is a key part of a system that fairly distributes the tax burden among property owners in a municipality.

In the preparation of assessing a property, it must first be determined whether a property is regulated or non-regulated.

Alberta Municipal Affairs prescribes rates and procedures based on the type of property, activity and/or production capability. (i.e. pipelines, electric power, transmission lines, telecommunication equipment)

There are four types of regulated property:

  • Farmland
  • Linear property
  • Machinery and equipment 
  • Railway

 

These properties are valued based on their estimated market value, and include residential, commercial, and industrial properties (i.e. hamlet residences, acreages, farm residences, warehouses, gas stations, restaurants, etc.)  

If the property is non-regulated, the assessor must determine a market value of the property.

The Municipal Government Act Section 1(1) describes market value as follows:

(n) “market value” means the amount that a property, as defined in section 284(1)(r), might be expected to realize if it is sold on the open market by a willing seller to a willing buyer;

This definition would make the following assumptions:

  • sufficient exposure time in the market
  • neither buyer or seller are under any undue pressure
  • both buyer or seller are well informed
  • payment for the property is typical for the market

There are three approaches to value when valuing real property. 

  • Sales Comparison Approach - Evaluations are based on the actual sale prices of other properties that have sold. This approach is most appropriate when the sales of similar properties are plentiful and reflect the typical market conditions. Of the three approaches it is the most easily understood by the public and courts.

  • Cost Approach - Based on the premise that a property's value is set by the “cost” of replacing an equally desirable substitute within a reasonable time frame. This approach works best for newer improvements where depreciation is less of a factor and special purpose properties which do not tend to sell on a regular basis. It's important to note that cost and value are NOT necessarily the same: cost is the amount required to produce the item, whereas value is related to how desirable the item is to a potential owner.
  • Income Approach - Based on the premise that a property's value is related to its ability to produce an income. This approach works best for properties that are typically rental type properties (i.e. apartment buildings, warehouses, etc.).

In Alberta, Non-regulated properties are valued according to the Market Value standard set out in the Municipal Government Act and Regulations. The Assessor utilizes all three approaches in evaluating these properties for assessment.

The valuation date is a fixed point in time at which assessment values are based. The valuation date ensures that all properties in a municipality are valued as of the same date. The valuation date set by the Municipal Government Act is July 1 prior to the tax year.

The second legislated date in the valuation process is the condition date. The condition date is the date on which the condition of the property is recorded for property assessment purposes. The condition date set by Municipal Government Act for property other than linear property is December 31 prior to the tax year.

For example: 2025 taxes are based on the 2024 assessment year. Therefore the physical condition date is December 31, 2024 and the valuation date is July 1, 2024 for the 2025 taxation.

Mass appraisal

Properties in Alberta are assessed using a method called mass appraisal. Mass appraisal is the process of valuing a group of propertied as of a given date, using common data, mathematical models, and statistical tests.

Data collection

Property data must be collected before an assessment can be prepared. Accurate and complete property records lead to more accurate assessed values. Detailed information is collected by on-site inspections, development/building permits issued from the County of Grande Prairie Planning Department, land titles and real estate listings.

Frequently Asked Questions

Not all property is assessable for property tax purposes. The Municipal Government Act outlines what property is assessable for taxation. The act defines property as:

  • A parcel of land
  • An improvement
  • A parcel of land and the improvements to it

This does not include furniture, automotives or other personal possessions.

Properties that are not assessed or tax include:

  • Publicly owned infrastructure
  • Minerals
  • Property in Indian reserves
  • Property in Metis settlements

Some properties are assessable, but not taxable. Properties that are assessed but then exempted (in whole or in part) from taxation include:

  • Environmental, municipal, and school reserves
  • Government properties such as hospitals, libraries and schools
  • Colleges and universities
  • Churches and cemeteries
  • Property owned by some non-profit organizations

The simple answer is "yes". Portable or movable structures such as frame and fabric buildings, sheds, relocatable offices, relocatable metal oilfield buildings, mobile homes, cabins, and sea cans (to name a few) are assessable.

These portable structures are defined in the Municipal Government Act in Part 9, Section 284 1(u) “structure” means a building or other thing erected or placed in, on, over or under land, whether or not it is so affixed to the land as to become transferred without special mention by a transfer or sale of the land.

The exception to this is if the structure is less than 10'x10' or 100 ft2. In this case, the assessment would not include the structure.

The Municipal Government Act Part 9, Division I, Section 297 defines non-residential as follows:

(4) (b)    “non residential”, in respect of property, means linear property, components of manufacturing or processing facilities that are used for the cogeneration of power or other property on which industry, commerce or another use takes place or is permitted to take place under a land use bylaw passed by a council, but does not include farm land or land that is used or intended to be used for permanent living accommodation;

The Municipal Government Act Part 9, Division I, Section 297 defines residential as follows:

4(c) “residential”, in respect of property, means property that is not classed by the assessor as farmland, machinery and equipment or non residential.

With a couple of exceptions, the Matters Relating to Assessment and Taxation Regulation, Alta Reg 220/2004 describes Machinery and Equipment as:

“ - materials, devices, fittings, installations, appliances, apparatus and tanks other than tanks used exclusively for storage, including supporting foundations and footings and any other thing prescribed by the Minister that forms an integral part of an operational unit intended for or used in

(i)    manufacturing,

(ii)    processing,

(iii)   the production or transmission by pipeline of natural resources or products or by products of that production, but not including pipeline that fits within the definition of linear property in section 284(1)(k)(iii) of the Municipal Government Act,

(iv) the excavation or transportation of coal or oil sands as defined in the Oil Sands Conservation Act,

(v)    a telecommunications system, or

(vi)    an electric power system other than a micro generation generating unit as defined in the Micro Generation Regulation (AR 27/2008),

whether or not the materials, devices, fittings, installations, appliances, apparatus, tanks, foundations, footings or other things are affixed to land in such a manner that they would be transferred without special mention by a transfer or sale of the land;

Assessments of vacant land is based on market value and the use of the property. For example farmland or vacant non-residential.

If the parcel of land meets the definitions of farmland as defined in Municipal Government Act and Regulations, it is a Regulated Assessment. The assessment is based on its productivity level based on the rates developed by Alberta Municipal Affairs.

The assessment of the land will reflect the use of the land based as of the condition date. There are many different situations where the use of a property will be different than the zoning. The Municipal Government Act only allows four assessment claes to assign to properties.

  • Class 1- Residential
    -Vacant residential
    -Improved residential

  • Class 2- Non-Residential
    -Vacant non-residential
    -Improved residential

  • Class 3 -Farmland

  • Class 4 -Machinery and Equipment

The valuation standard for a parcel of land is either market value or if the parcel of land meets the definitions of farming operations, it is assessed using the regulated farmland rates based on productivity.

A parcel of land that is zoned for agriculture, but is not being used farming operations or meet the definition of farmland it will be assessed at market value.

The Assessment/Tax Notices are generally mailed out in May. The assessment value on your notice will be reflective of the physical condition and level of completion as of December 31 of the previous year of the tax/assessment notice.

For example, if a home was partially complete as of condition date, the assessment would include a value for the land (plus services), site improvements, and the value of the building based on the stage of completion.

A Property assessment is determined based on the physical condition of the property as of December 31, prior to the year in which the tax is imposed. If the fire damage was present on or before the December 31 date, the assessment/tax notice will reflect the impact on the value due to the fire.

If the fire damage occurred in the same year in which you receive your assessment/tax notice, your assessment will not consider fire damage or repairs until the following tax year.

A sale price might not equal market value for any of the following reasons:

  • The sale might not have occurred in the assessment .

  • The purchaser might not have been aware that similar
    properties were selling for more or less than the price for
    which the property was purchased.

  • The buyer or seller may have been unduly motivated (for
    example, transferred to another city, needed to sell property
    as part of a divorce settlement, etc.).

  • The sale may have involved a trade, partial interest, special
    financing, personal property, or assumed leases.

Each year, municipal councils determine the amount of money they need to raise through property taxes to operate their municipality. These operating costs will be used to determine the tax rates or mill rates.

A simple example to estimate the tax rate calculation is expressed in the following formula: Operating Costs / Assessment base = Tax rate.

The tax rate is applied to each individual property assessment using the following formula: Property assessment x Tax rate = Taxes payable.

This formula means that the assessed value of the property in dollars is multiplied by the tax rate set by the municipality. The result is the amount of taxes to be paid for each assessed property. A municipality may adjust its tax rate on a yearly basis depending on its revenue requirement. The tax rate a municipality chooses to set depends on the assessment base in the municipality and the amount of money it needs to generate using the property tax.

If the council requires more revenue to run the municipality and the assessment base in the municipality has remained the same, the council will have to increase its tax rate to generate the additional revenue.
