Last year, Calgarians saw an increase in their property assessment values by some 15 per cent, but some homeowners saw far greater increases.

Among the communities that saw the biggest increases, one faced a 47 per cent increase in assessments for single family homes, while another saw a 79 per cent increase increase in condo assessments.

Using open data from the City of Calgary, LWC was able to look in more detail at where property assessments changed from 2023 to 2024.

The latest assessments are based on market data collected on July 1, 2024 and physical condition on Dec. 31, 2024, and used for the 2025 property tax year.

That data confirmed previous city assessment projections, with single residential homes seeing a 14 per cent increase in change, and residential condominiums seeing a 22 per cent increase.

When looking at specific types of property sub-use types, those percentages trended slightly upward. Single-detached homes and single-detached homes with backyard suites only saw a 15 per cent increase, while low-rise and high non-rental apartment condos saw a 25 per cent increase.

Biggest increases for single detached homes came in developing communities

The community of Hotchkiss, located in southeast Calgary, saw the biggest increase for single detached homes with a 47.2 per cent increase, largely driven by the increase in the number of assessed homes from 44 to 231 in the developing community.

The next largest increases at 23.5 per cent, 20 per cent, and 20 per cent for Alpine Park, Rangeview, and Haskayne, were also driven by large increases in the number of homes in those communities.

Elboya saw the biggest percentage change for a community with little change in the number of single-detached homes at 19 per cent, with a median increase of $200,000.

The biggest overall increase in median single-detached home prices was seen in the community of Bel-Aire, at $365,000 leading to an overall of 17.2 per cent.

It was also the community with the highest median assessed value per unit in Calgary, at $2,485,000.

The established community of Coventry Hills saw the lowest median assessment increase, at $41,000 and 8 per cent, while Homestead had the lowest percentage increase at 6.5 per cent ($46,250).

The most valuable community of single detached homes in the city was in Cranston, which was also the largest with 5,846 units and an assessed value of $4,903,557,000.

Condo assessments increase by larger percentages than houses

For non-rental condominiums, the developing community of Wolf Willow saw the biggest percentage assessment increase with 79 per cent, going from a median of $195,500 in 2024 to $350,750 in 2025. It also saw an increase in the number of completed condo units in the community going from 70 to 140.

For communities with more than a handful of condo units, Southwood saw the largest percentage increase at 45 per cent, going from a median $152,500 last year to $220,500.

The Beltline, which was home to the most assessed non-rental condos in the city with 10,162—or more than 13 per cent of the entire stock of the city—saw an median increase of over 16 per cent by $45,500.

That community was also the most valuable by property type, being assessed at $3,695,823,000.

Eagle Ridge had the highest median assessed condo values for all Calgary communities, with its 10 condos assessed with a median of value of $1,540,000.

Douglesdale/Douglasglen with its 343 units, saw the second highest median assessment value of $523,500.

Townhouses see largest percentage increases in Calgary

The number of assessed townhouses increased in Calgary over the past year, and along with the nearly four per cent increase in homes came a 21 per cent increase in assessed value.

The developing community of Pine Creek in the deep southwest of the city saw a triple digit increase in assessments owing to 87 new units. Median assessments rose from $236,000 in 2024 to $522,000 in 2025—or 121 per cent—going from a below average assessment last year to an above average in 2025.

Shaganappi also saw some blistering increases in assessments, rising by 91 per cent and a median increase of $278,000 for units.

Forest Lawn in the southeast also saw large increases despite only three new townhouses being assessed from 2024 to 2025. That community saw a median increase of 37 per cent, or $64,000.

Bowness, which had been in the news for both the Bearspaw water main break in 2024, along with strong opposition by residents to townhouses being built in the community, saw a 28 per cent increase in the median assessed value for those units, representing a $72,750 increase. The change in assessed units was 14 between 2024 and 2025.

Cliff Bungalow saw a median decrease in assessments by nearly five per cent, with townhouse owners seeing a median drop of $55,000 on their assessments, going from the median of $1,170,000 in 2024 to $1,115,000 in 2025.

Bayview had the highest median assessed townhouses in the city, at $1,505,000.

Sage hill was the the most valuable community of townhouses in the city, with an assessed value of $599,953,000, followed by McKenzie Towne with a value of $587,820,500.
