Calgary's detached market is in a rare state: just 2.1 months of inventory. In real estate analysis, inventory below 4 months typically indicates a seller's market, and below 3 months is extremely tight supply. At 2.1 months, it means: if you list a reasonably priced detached home today, it will likely sell within weeks.

March data confirms this assessment. The detached sales-to-new-listings ratio (SNLR) rebounded to 61%, well above the 40% balanced threshold. Prices showed modest month-over-month increases, with popular areas like Northwest, West, South, Southeast, and East districts having inventory below 2 months.

Why is detached supply so tight? The answer lies on the supply side, not demand. In 2022-2023, Calgary experienced a record-breaking construction boom, with detached starts surging to historic highs. But as interest rates rose and market demand cooled, developers sharply cut new projects. In 2024-2025, detached new construction starts fell by approximately 40%.

The lag effect of supply is now showing. When new construction starts fall, new home supply dries up about 18 months later. That's exactly what Calgary's detached market is experiencing. It's not that demand suddenly became stronger — it's that supply suddenly became scarcer. This logic of "supply contraction pushing prices higher" is similar to Vancouver's detached bottom signals — except Calgary's contraction has been more severe and extreme.

As Ann-Marie Lurie, chief economist at CREB®, wrote in the report: "If you only look at aggregate data, the market appears relatively balanced. But looking deeper, we see a range from tight detached conditions to a buyer's market for condos. This is supporting upward momentum in detached prices and downward pressure in the condo segment."

In extreme contrast to detached homes, the condo market is trapped in an oversupply situation. Inventory is near 5 months, approaching historic highs not seen since the 2008 financial crisis. The sales-to-new-listings ratio is only 40%, firmly in deep buyer's market territory. Prices have plunged 9.2% year-over-year, with all districts seeing declines — the South and North districts down more than 4%.

Why have condos reached this point? The answer again lies on the supply side. During the 2022-2023 construction boom, condos were the main driver. Numerous condo projects launched during that period and are now being delivered after 2-3 year construction cycles. At the same time, investor-owned condos face falling rents and are accelerating their exits. This "condo oversupply" is a national phenomenon — Montreal condo inventory surged 21%, and Toronto's condo market is also in deep adjustment. Calgary is simply the most extreme case of this national trend.

In Q1 2026, Calgary condo prices fell another 3% from Q4 2025. This is the fifth consecutive quarter of declines. The dual challenges of oversupply and weak demand leave the condo market with no signs of short-term improvement.

More concerning, the condo supply wave may not have peaked. According to City of Calgary data, approximately 26,000 residential units are currently under construction, a significant portion of which are condos. This means condo supply will remain high for the next 12-18 months.

The extreme divergence between Calgary's detached and condo markets stems from fundamentally different supply and demand structures.

On the supply side: Detached supply is contracting, condo supply is expanding. Detached new construction starts fell sharply in 2024-2025, causing new home supply to dry up in 2026. Condo projects launched in 2022-2023 are now at peak delivery. This supply wave is the "lag effect" of the 2022-2023 construction boom.

On the demand side: Detached buyers are predominantly owner-occupiers, while condo buyers are mostly investors. Owner-occupiers have higher tolerance for price fluctuations and view their home as a long-term asset. Investors are more sensitive to cash flow — when rents fall and vacancy rates rise, they choose to exit. March data shows Calgary condo rents down about 5% year-over-year, with vacancy rates rising to 5.5%, pushing investors to sell.

On price elasticity: Detached prices have a higher "floor." Detached prices include significant land costs that don't disappear even in a downturn. Condo prices are dominated by construction costs, making them more elastic when oversupply occurs.

CREB® data also shows divergence within the detached market itself. The Northwest, West, South, Southeast, and East districts have inventory below 2 months — very tight. The City Center and North districts are relatively balanced. The Northeast district continues to have oversupply. Even within the detached market, location choices matter significantly.

Calgary's surrounding towns — Airdrie, Cochrane, Okotoks — show varying degrees of "balance," but concerns also exist.

Airdrie: SNLR above 50%, inventory around 3 months, benchmark $512,800 (-5% YoY). The market is relatively balanced, but the new home market and increased supply choices in North Calgary continue to pressure prices. The year-over-year decline of 5% means stabilization signals remain unclear.

Cochrane: SNLR below 50%, rising inventory, benchmark $561,200 (-4% YoY). New listings are growing faster than sales, driving inventory accumulation. The market is shifting from tight to balanced. Despite seasonal price increases, year-over-year prices are still down 4%, requiring close attention to inventory trends.

Okotoks: Q1 sales slightly down, inventory still low, benchmark $618,100 (-1% YoY). This area shows the strongest price resilience, with modest increases from end-2025. However, slowing sales and rising inventory trends are worth watching — it has not fully escaped adjustment pressure.

For investors, the extreme divergence between Calgary's detached and condo markets means investment logic is completely different. If you're planning a 2026 home buying strategy, finding oversold opportunities with SNLR – tiered strategies may be more valuable than looking at national macro data.

Detached homes: Supply depletion is the core logic. The investment value of detached homes lies in supply scarcity. When new construction starts fall sharply, supply dries up about 18 months later, and prices find support. For detached investors, the core risk isn't price decline — it's declining liquidity. In a supply-depleted market, shrinking transaction volume may be more concerning than price drops.

Condos: The supply wave is the core risk. The investment risk of condos lies in oversupply. When large numbers of new condos are delivered at once, both rents and prices come under pressure. For condo investors, the core question is: can cash flow cover holding costs? In an environment of falling rents and rising vacancy rates, the answer to this question is increasingly uncertain.

Alberta's economic backdrop: Alberta's natural resources sector added 10,000 jobs, nearly half of which were in the province. The energy sector's resilience provides support for Calgary's economy. But this also means Calgary's housing fate is highly correlated with energy prices. If oil prices fall, everything could change. This contrasts sharply with Canada's unemployment at 6.7% — the jobs winter — Calgary's energy jobs are growing while the rest of the country faces employment pressure.

Based on current data, the trajectory of Calgary's 2026 housing market will depend on three key variables:

Variable #1: When detached supply can recover. The sharp decline in detached new construction starts is the root cause of current supply depletion. If new starts recover, supply pressure will ease. If new starts remain low, supply depletion will continue. Currently, developers remain cautious about launching new projects, meaning supply recovery may take longer.

Variable #2: When the condo supply wave passes. The condo supply wave is the "lag effect" of the 2022-2023 construction boom. This delivery peak is expected to last through the end of 2026. Condo market stabilization requires a significant slowdown in supply growth, which may not happen until 2027.

Variable #3: Energy price trends. Calgary's economy is highly correlated with energy prices. If oil prices remain above $70/barrel, Calgary's economy will continue to find support. If oil prices fall, the housing market will face greater pressure. Currently, oil prices are relatively stable, but geopolitical risks always exist.
