An infill is a house built on a lot that already had one. These are the new detached homes, half duplexes and row houses going up on established inner-city streets rather than at the edge of the city — several of them are for sale right now across the 15 communities where this is a real market.
A house built from 2015 onward on a lot inside the established city that already had a house on it. The old one comes down and one or two new ones go up in its place. That is the whole idea: the city grows inward, on streets that already have services, schools, trees and bus routes, instead of outward onto new land.
This page filters on the year the home was built together with the ground-oriented property types — detached, semi-detached and half duplex, row and townhouse, and full duplex. New apartment buildings are excluded deliberately. A year filter on its own does not mean infill: in several inner-city communities almost all of the new construction is apartment towers, and in Calgary's East Village 34 of 37 recent listings are apartments. Those are new condominium markets, and they are covered by our condo pages. Calling them infill would use the word to mean something it does not.
It follows the arithmetic of land. When a lot close to downtown is worth more than the house standing on it, rebuilding becomes the rational thing to do, and a lot that can take two attached homes rather than one detached house spreads its land cost across two sales. That is why infill concentrates in a ring of established communities a few kilometres out — close enough that land is valuable, old enough that the housing stock is at the end of its life, and zoned to allow more than one home where the district permits it.
It also means rebuilding runs block by block rather than evenly. Two streets in the same community can look a decade apart, which is why the community pages below are more useful than any citywide figure.
Both are new houses and almost nothing else about them is the same. An infill sits on an existing lot on an existing street — usually narrower, often with a lane, surrounded by mature trees and houses from another era, with schools, shops and transit already built. A new suburban house sits on a new lot in a community where those things are still coming. Infill trades lot size and garage space for a location that is already finished, and it costs more per square foot for exactly that reason.
The practical differences matter more than the philosophical ones. Infill lots are tight, so construction access, grading and drainage between neighbours are live issues. Streets are narrow and parking is often on-street. And you are buying into an existing neighbourhood rather than one that will be defined by whoever moves in next.

Sold figures cover September 2025 to August 2026 and are aggregates for that window — 510 sales of houses built 2015 or later across 15 communities. “Median older” is the median for houses in the same community built before 2015, over the same window, on the same four property types, so the only variable between the two columns is the year the house was built. Listed-now counts are read live.
New does not mean unexamined, and a new house is not a lower-risk purchase than an older one — it is a differently-risked one.
Get an independent inspection. A house finished last year can still have grading, drainage, envelope or mechanical problems, and they are far cheaper to argue about before possession than after. Ask who the builder is and walk two or three of their earlier projects; quality across a building wave this size varies more than the finishes suggest. Confirm the warranty. Alberta requires new homes to carry coverage, and it runs from the date the home was first occupied rather than from your possession date, so a spec house that sat can have materially less left than you assume — our guide to Alberta new home warranty sets out what each stage protects. Check what is actually included: landscaping, fencing and the garage are the items most often still outstanding.
What can be built on a given lot is set by its land use district, and that is also what decides whether the empty lot beside you becomes one house or four. Our R-CG guide covers the district most inner-city rowhouse and duplex infill is built under. Confirm the district for a specific address with the City rather than relying on a listing.
Each of these is its own page with live MLS® listings and its own measured picture. A community appears here only where new ground-oriented houses are at least half of its recent new stock — which is what separates an infill market from a condo market that happens to be new.
We can set a saved search across every community above, and talk through which builders and which streets are worth your time — no obligation.
