How property assessment works in Alberta

Your assessment is the municipality’s estimate of what your home would have sold for, used to share out the property tax.

Market value on a set date

In Alberta a residential assessment estimates market value as of 1 July of the year before the notice, for the property as it was on 31 December. So a notice mailed in January 2027 reflects the market of July 2026 and the home as it stood at the end of 2026.

Mass appraisal

Assessors don’t visit every home each year. They use recent sales and each property’s recorded details (size, age, lot, garage, basement, location) in models that value thousands of homes at once. That is why the recorded details matter so much: a wrong floor area or a missing feature changes the result.

What the notice shows

The assessed value, the property’s class (residential), its details as the municipality has them, and the last date to file a complaint. Check those details first.

Where the numbers on this site come from

Each municipality publishes its assessment roll as open data. This site copies it, groups it by community, and finds similar homes near yours. Sources and licences.
