Calculating Property Value

Want to understand how the value of your property, building or lot is calculated? Find out everything you need to know about the factors that influence its value.

Property values that appear on the assessment roll correspond to the property’s exchange value on the free and open market. It is the most probable selling price paid by a potential buyer in a private sale.

Factors that influence the value of your property

To determine the market value of a property, the city appraiser takes into account real estate market conditions for the 18-month period prior to the coming into force of the assessment roll. For the 2023-2024-2025 rolls, this date is July 1, 2021.

The main factors that determine value are:

• Location

• Lot area

• Size of the building(s)

• Age of the property, adjusted to account for any renovations or major additions

• Quality of the construction

• Income generated by the property, if applicable
