Who Lives in Diamond Cove
Diamond Cove holds 625 residents across 271 properties on the community's small 0.439 km² SE footprint. The resident base skews mature and owner-heavy — around 36% of residents are aged 65 or older, one of the highest senior shares in SE Calgary, reflecting a community whose original 1989–1991 buyers have largely aged in place. Household incomes have historically run comfortably above the citywide median, in line with the essentially all-detached estate character and the small-lot Bow River corridor location. Rental and condo shares are both very low, so almost every household is an owner-occupier in a detached home. Population has drifted down from around 730 residents in the 2016 census as the original buyers age through the community. For a comparable SE detached community at a similar price and mix, the McKenzie Towne profile covers a larger master-planned peer further south along the same Bow River corridor.

Living in Diamond Cove
Housing in Diamond Cove is essentially all single-family detached — the community was recognised in 1973 but built out in the 1989–1991 window as a small estate development, and the resulting fabric is a compact grid of detached homes with almost no rental or condo share. The Bow River runs along the entire east boundary, and the Bow River pathway on that side gives residents direct access to one of Calgary’s core outdoor loops for cycling, running, and off-leash dog walking. Bow Bottom Trail forms the west boundary and is the community’s main north–south connector out toward Anderson Road and Deerfoot Trail. Anderson Road along the north edge is the arterial that carries Diamond Cove traffic west toward Macleod Trail and the Anderson Red Line CTrain station further west; there is no LRT inside the community. The interior streets loop off Bow Bottom Trail in a quiet cul-de-sac layout, and most homes have been owner-occupied since the original 1989–1991 buildout with only slow turnover on the assessment roll. Haultain Memorial Elementary and Wilma Hansen Junior High serve as the local CBE schools drawing from Diamond Cove and the adjacent SE Bow River communities. For a same-batch peer immediately west across Bow Bottom Trail, the Bonavista Downs profile is the direct west neighbour and closest reference.
Things to do in Diamond Cove
The Bow River pathway runs along the east edge of the community and is the primary outdoor draw — a paved multi-use loop connecting Diamond Cove residents into the wider SE Bow River pathway network for cycling, running, and off-leash dog walking. Bow Bottom Trail on the west edge is the community’s main connector into the Lake Bonavista retail corridor a short drive north, where the Lake Bonavista profile covers the direct north-west parent-community reference with its lake, retail, and schools cluster. There is no CTrain station inside Diamond Cove; the closest LRT is the Red Line’s Anderson station west along Anderson Road, and Canyon Meadows further west along the same corridor. Any specific business inside or near the community is easiest to find through the Diamond Cove business directory, which pulls current City of Calgary business-licence records. For a similar detached-heavy SE Bow River community with comparable estate character and river-corridor access, the Riverbend profile is the closest north Bow-River reference.
The Diamond Cove real-estate read
Diamond Cove’s average assessed value sits at $906K against the citywide $732K — well above the citywide average, reflecting the community’s essentially all-detached estate character on the small 270-property footprint with direct Bow River corridor access. Values rose 18.5% year-over-year against the citywide 15.2% pace, running ahead of the wider Calgary market during the current cycle. Building activity for the community’s small footprint sits at 10 permits filed since 2024, weighted toward interior renovations and infill work as the original 1989–1991 estate homes turn over on the assessment roll. The community’s average build year sits around 1992, reflecting the concentrated late-1980s and early-1990s buildout. On safety, disorder runs at 51.2 events per 1,000 residents against the citywide baseline of 54 per 1,000 — well below the citywide baseline. Year-over-year, the community’s disorder rate held roughly steady compared with the year before. For another SE Bow River community at a similar detached-dominant character, the Canyon Meadows profile is a close reference on value and mix.
Common Questions About Diamond Cove
Why are there two average values on this page?
The page shows two related but distinct figures because they come from two different official City of Calgary datasets with different aggregation methods. The Average Property Assessment (in the snapshot at the top of the page and in the "vs Calgary Average" card) is drawn from the City's live current-year assessment feed, using a broad aggregation across all residential parcels. The Year-End Assessment Roll figures in the Property Values chart and table below come from a separate dataset that captures each year's official year-end roll, using a narrower per-year methodology. Both are official data — the small difference between them is normal and reflects the different aggregation windows. For an at-a-glance current value, use the Average Property Assessment; for authoritative year-over-year trends, use the Assessment Roll.
What's the average house price in Diamond Cove?
The average assessed value in Diamond Cove sits at $906K against the citywide $732K — well above the citywide average, reflecting the community's essentially all-detached estate character on a compact 270-property footprint with direct Bow River corridor access. Assessed value is a property-tax measure and differs from a market sale price.
How is the Diamond Cove real estate market?
Diamond Cove's average assessed value rose 18.5% year-over-year against the citywide 15.2% pace, running ahead of the wider Calgary market during the current cycle. Inventory is very thin — the community holds only 271 properties on a 0.439 km² SE footprint, so homes turn over infrequently.
Is Diamond Cove a good place to live?
Diamond Cove pairs a small SE estate character with direct Bow River pathway access on the east edge and Anderson Road connections west toward the Red Line at Anderson station. The fit for buyers depends on priorities: those wanting a detached-heavy, owner-occupied SE community with river-corridor access and quiet interior streets tend to land here.
Is Diamond Cove safe?
Disorder in Diamond Cove runs at 51.2 events per 1,000 residents against the citywide baseline of 54 per 1,000 — well below the citywide baseline. Year-over-year, the community's disorder rate held roughly steady compared with the year before. The disorder measure covers social-disorder calls handled by Calgary Police Service; overall crime is measured separately.
