What Is a Calgary Property Assessment?
A Calgary property assessment is the City of Calgary’s estimate of what your property was worth on July 1 of the previous year — the fixed valuation date the City uses to build every year’s tax roll. The 2025 assessment roll values 587,466 Calgary properties, and the average residential assessment is $625,107. Your assessment is the number the City multiplies by the annual property-tax rate to calculate your tax bill.

How Calgary calculates your assessment
Calgary uses a process called mass appraisal. City assessors do not visit each home individually; they build statistical models from every arm’s-length sale that happened in the preceding calendar year, then apply those models to every property in that community based on characteristics the City already has on file — lot size, floor area, year built, quality, and location. Every property is valued as of the same fixed date, July 1 of the year before the assessment is issued. The 2025 assessment roll uses a July 1, 2024 valuation date.
Because the valuation date is fixed, two neighbours whose homes sell for identical prices in the same year end up with matching assessments. The upside is fairness at the community level. The downside is that a fast-moving market can leave your assessment several months behind actual sale prices by the time you receive the notice in January.
Assessment, market price, and tax bill — three different numbers
People often use these three interchangeably, but each one answers a different question.
| Number | Who sets it | What it tells you |
|---|---|---|
| Assessed value | City of Calgary | Estimated market value on July 1 last year — used to calculate your property tax. |
| Market / sale price | Buyer and seller | What a home actually sells for on the open market on a specific date. |
| Property tax bill | Assessed value × municipal + provincial mill rate | What you owe the City each year. |
The 2025 tax roll by property class
The City assesses three broad classes of property, each with a separate tax rate. Residential covers houses, condos, and rental buildings. Non-residential covers commercial and industrial. Farm land is a small remnant class inside city limits.
| Property class | Properties on the 2025 roll | Average assessed value |
|---|---|---|
| Residential | 561,525 | $625,107 |
| Non-residential | 25,657 | $4,304,420 |
| Farm land | 284 | $117,542 |
Where to look up your own assessment
The City mails an Assessment Notice each January and posts a lookup at assessmentsearch.calgary.ca for property owners. On this site, the free Calgary Address Lookup tool shows the same current-year assessment for any residential address, alongside its year-built, community, and daily-essentials nearby.
